CHECKING BRAKE FLUID
To check the fluid level, simply look at the see–through reservoir. The level should be between the ”MAX” and ”MIN” lines on the tank.
It is normal for the brake fluid level to go down slightly as the brake pads wear. So be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it may indicate a serious mechanical problem.
If the level is low, add FMVSS No.116 DOT 3 or SAE J1703 brake fluid to the brake reservoir.
Remove and replace the reservoir cap by hand. Add brake fluid up to the ”MAX” line.
Use only newly opened brake fluid. Once opened, brake fluid absorbs moisture from the air, and excess moisture can cause a dangerous loss of braking efficiency.
CAUTION
Take care when filling the reservoir because brake fluid can harm your hands or eyes and damage painted surfaces. If flu i d gets in your hands or eyes, flush them with clean water.
NOTICE
If you spill some of the fluid, be sure to wipe it off to prevent it from damaging the parts or paintwork.
For vehicles with traction control system only: Idle the engine while pouring brake fluid into the reservoir.

FLUID
Check the fluid level on the dipstick. If necessary, add automatic transmission fluid DEXRON
II or III.
If the vehicle has been driven around 80 km/h (50 mph) for 20 minutes (a little more in frigid temperatures), the fluid is hot (60C – 80C or 140F – 175F). You may also check the level when the fluid is cold (about room temperature, 10C – 30C or 50F – 85F) if the engine has not been run for about five hours.
1. Clean all dirt off the reservoir.
2. Remove the reservoir cap by turning it counterclockwise and wipe the dipstick clean.
3. Reinstall the reservoir cap.
4. Remove the reservoir cap again and look at the fluid level. If the fluid is cold, the level should be in the ”COLD” range on the dipstick. Similarly, if it is hot, the fluid level should be in the ”HOT” range. If the level is at the low side of either range, add automatic transmission fluid DEXRON level within the range.

CAUTION
The reservoir may be hot so be careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steering could be damaged.
When adding the power steering fluid, avoid spilling it. The generator under the power steering reservoir could be damaged if fluid is spilled on it.
CHECKING TIRE PRESSURE
The recommended cold tire pressures, tire size and the vehicle capacity weight are given on the label.
You should check the tire pressures every two weeks, or at least once a month. And don’t forget the spare! The pressure for the spare tire should be same with that for the standard tire. (See page 232 or 234.) Incorrect tire pressure can reduce tire life and make your vehicle less safe to drive.
Low tire pressure results in excessive wear, poor handling, reduced fuel economy, and the possibility of blowouts from overheated tires. Also, low tire pressure can cause poor sealing of the tire bead. If the tire pressure is excessively low, there is the possibility of wheel deformation and/or tire separation. So keep your tire pressures at the proper level. If a tire needs frequent refilling, have it checked by your Lexus dealer.
237
Page 9
CHASSIS
High tire pressure produces a harsh ride, handling problems, excessive wear at the center of the tire tread, and a greater possibility of tire damage from road hazards.
The following instructions for checking tire pressure should be observed:
The pressure should be checked only when the tires are
cold. If your vehicle has been parked for at least 3 hours
and has not been driven for more than 1.5 km or 1 mile since, you will get an accurate cold tire pressure reading.
Always use a tire pressure gauge. The appearance of the
tire can be misleading. Besides, tire pressures that are even just a few pounds off can degrade handling and ride.
Do not bleed or reduce tire pressure after driving. It is
normal for the tire pressure to be higher after driving.
Never exceed the vehicle capacity weight. The
passengers and luggage weight should be located so that the vehicle is balanced.
Be sure to reinstall the tire valve caps. Without the valve
caps, dirt or moisture could get into the valve core and cause air leakage. If the caps have been lost, have new ones put on as soon as possible.
ROTATING TIRES
To equalize tire wear and help extend tire life, Lexus recommends that you rotate your tires approximately every 12000 km (7500 miles). However, the most appropriate timing for tire rotation may vary according to your driving habits and road surface conditions.
The wheel assemblies must be rotated as illustrated above. When rotating tires, check for uneven wear and damage.
Abnormal wear is usually caused by incorrect tire pressure, improper wheel alignment, out–of balance wheels, or severe braking.
Before storing radial, snow or studded tires, mark the direction of rotation and be sure to install them in the same direction when using them again. Tires should be stored in a cool dry place.
238

CHASSIS
CHECKING AND REPLACING TIRES
When to replace your tires
Replace the tires when the tread wear indicators show. The location of the tread wear indicators is shown by the marks such as “TWI” or “ each tire.
The tires on your Lexus have built–in tread wear indicators to help you know when the tires need replacement. When the tread depth wears to 1.6 mm (0.06 in.) or less, the indicators will appear. If you can see the indicators in two or more adjacent grooves, the tire should be replaced.
The effectiveness of snow tires is lost if the tread wears down below 4 mm (0.16 in.).
If you have tire damage such as cuts, splits, cracks deep enough to expose the fabric, or bulges indicating internal damage, the tire should be replaced.
” molded on the sidewall of
If a tire often goes flat or cannot be properly repaired due to the size or location of a cut or other damage, it should be replaced. If you are not sure, consult with your Lexus dealer.
If an air loss occurs while driving, do not continue driving with a deflated tire. Driving even a short distance can damage a tire beyond repair.
Any tires which are over 6 years old must be checked by a qualified technician even if damage is not obvious.
Tires deteriorate with age even if they have never or seldom been used.
This also applies to the spare tire and tires stored for future use.
Uniform tire quality grading
This information has been prepared in accordance with regulations issued by the National Highway Traffic Safety Administration of the U.S. Department of Transportation. It provides the purchasers and/or prospective purchasers of Lexus vehicles with information on uniform tire quality grading.
Your Lexus dealer will help answer any questions you may have as you read this information.
DOT quality grades – All passenger vehicle tires must conform to Federal Safety Requirements in addition to these grades. Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A
239
Page 11
CHASSIS
Tread wear – The treadwear grade is a comparative rating
based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 – 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.
Traction AA, A, B, C – The traction grades, from highest to lowest, are AA, A, B and C, and they represent the tire’ s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking (straight ahead) traction tests and does not include cornering (turning) traction.
Temperature A, B, C – The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.
Warning: The temperature grades for this tire are established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.
Tire selection
When replacing a tire, use only the same size and construction as originally installed and with the same or greater load capacity.
Using any other size or type of tire may seriously affect handling, ride, speedometer/odometer calibration, ground clearance, and clearance between the body and tires or snow chains.
Do not mix radial, belted, or conventional tires on your vehicle.
Do not use tires or wheels other than the manufacturer’s recommended size.
It can cause dangerous handling characteristics, resulting in loss of control. If you need to change from conventional tires to radial tires or vice versa, replace them as a set.
240
Page 12
CHASSIS
INSTALLING SNOW TIRES AND
CHAINS
When to use snow tires or chains
Snow tires or chains are recommended when driving on snow or ice.
On wet or dry road, conventional or radial tires provide better traction than snow or studded tires.
Snow tire selection
If you need snow tires, select the same size, construction and load capacity as the original tires on your Lexus.
Do not use tires other than stated above. Since your vehicle has radial tires as original equipment, make sure your snow tires also have radial construction. Do not install studded tires without first checking local regulations for possible restrictions.
Snow tire installation
Snow tires should be installed on all wheels.
Installing snow tires on the rear wheels only can lead to an excessive difference in road grip capability between the front and rear tires which could cause loss of vehicle control.
CAUTION
Snow tires should be inflated as described below, but
never above the maximum cold tire pressure shown on the tire sidewall.
2
225/55R16 ... 220 kPa (2.2 kgf/cm
Never drive over 120 km/h (75 mph) with any type of
snow tires.
or bar, 32 psi)
Tire chain selection
Regulations regarding the use of tire chains vary according to location or type of road. Always check the local regulations before installing chains.
Use SAE Class ”S” type radial tire chains, with the exception of radial cable chains or V–bar type chains.
Chain installation
Install the chains on the rear tires as tightly as possible. Do not use tire chains on the front tires. Retighten chains after driving 0.5 – 1.0 km (1/4 – 1/2 mile).
When installing chains on your tires, carefully follow the instructions of the chain manufacturer.
241
Page 13
CHASSIS
CAUTION
Do not exceed 50 km/h (30 mph) or the chain
manufacturer’s recommended speed limit, whichever is lower.
Drive carefully avoiding bumps, holes, and sharp
turns, which may cause the vehicle to bounce.
Avoid sharp turns or locked–wheel braking, as use of
chains may adversely affect vehicle handling.
REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bending, cracks or heavy corrosion, the wheel should be replaced.
If you fail to replace damaged wheels, the tire may slip off the wheel or cause loss of handling control.
Replacement with used wheels is not recommended as they may have been subjected to rough treatment or high mileage and could fail without warning. Also, bent wheels which have been straightened may have hidden structural damage and therefore should not be used. Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width, and offset.
Correct replacement wheels are available at your Lexus dealer.
A wheel of a different size or type may adversely affect handling, wheel and bearing life, brake cooling, speedometer/odometer calibration, stopping ability, headlight aim, bumper height, vehicle ground clearance, and tire or snow chain clearance to the body and chassis.
242
Page 14
ALUMINUM WHEEL PRECAUTIONS
After driving your vehicle the first 1600 km (1000 miles),
check that the wheel nuts are tight.
If you have rotated, repaired, or changed your tires, check
that the wheel nuts are still tight after driving 1600 km (1000 miles).
When using tire chains, be careful not to damage the
aluminum wheels.
Use only the Lexus wheel nuts and wrench designed for
your aluminum wheels.
When balancing your wheels, use only Lexus balance
weights or equivalent and a plastic or rubber hammer.
As with any wheel, periodically check your aluminum
wheels for damage. If damaged, replace immediately.
SUSPENSION AND CHASSIS
CAUTION
Do not modify the suspension/chassis with lift kits, spacers, springs, etc. It can cause dangerous handling characteristics, resulting in loss of control.

CHECKING BATTERY CONDITION
Precautions
CAUTION
BATTERY PRECAUTIONS The battery produces flammable and explosive
hydrogen gas. Do not cause a spark by contacting the battery
terminals with tools. Do not smoke or light a match near the battery. The electrolyte contains poisonous and corrosive
sulfuric acid.
Avoid contact with eyes, skin or clothes.Never inhale or swallow electrolyte.Wear protective safety glasses when working near
the battery. Keep children away from the battery. EMERGENCY MEASURES If electrolyte gets in your eyes, flush your eyes with
clean water for at least 15 minutes and get immediate
medical attention. If possible, continue to apply
water with a sponge or cloth while traveling to the
medical office.
248
Page 22
ELECTRICAL COMPONENTS
If electrolyte gets on your skin, thoroughly wash the
contact area. If you feel a pain or burn, get medical attention immediately.
If electrolyte gets on your clothes, there is a
possibility of its soaking through to your skin, so immediately take off the exposed clothing and follow the procedure above, if necessary.
If you accidentally swallow electrolyte, drink a large
quantity of water or milk. Follow with milk of magnesia, beaten raw egg or vegetable oil. Then go immediately for emergency help.
Checking battery exterior
Check the battery for corroded or loose connections, cracks, or loose hold–down clamps.
1. If the battery is corroded, wash it off with a solution of warm water and baking soda. Coat the terminals with grease to prevent further corrosion.
2. If the connections are loose, tighten the clamp bolts –but do not overtighten.
3. Tighten the hold–down clamp only enough to keep the battery firmly in place. Overtightening may damage the battery case.
249
Page 23
ELECTRICAL COMPONENTS
NOTICE
Make sure the engine and all accessories are turned off before performing maintenance.
When checking the battery, remove the ground cable first and reinstall it last.
Be careful not to cause a short circuit with tools.
Take care no solution gets into the battery when washing it.
Checking battery fluid
Check the battery condition by the hydrometer color.
BLUE – Good condition. WHITE – Charging necessary. Have the battery checked by
your Lexus dealer. RED – Have the battery checked by your Lexus dealer.
NOTICE
Do not refill the battery with water.
250
Page 24
ELECTRICAL COMPONENTS
BATTERY RECHARGING
PRECAUTIONS
During recharging, the battery is producing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be sure to disconnect the ground cable.
2. Make sure the power switch on the recharger is off when connecting the charger cables to the battery and when disconnecting them.
CAUTION
Always charge the battery in an unconfined area. Do
not charge the battery in a garage or closed room where there is not sufficient ventilation.
Only do a slow charge (5 A or less). Charging at a
quicker rate is dangerous. The battery may explode causing personal injuries.
NOTICE
Never recharge the battery while the engine is running. Also, make sure all accessories are turned off.
CHECKING AND REPLACING THE
BLADE TYPE FUSES
1. Turn the ignition switch off and open the fuse box lid.
Determine which fuse may be causing the problem. The lid of the fuse box shows the name of the circuit for each fuse.
251
Page 25
ELECTRICAL COMPONENTS
2. Make sure t h e i noperative component is turned off. Pull the suspected fuse straight out with the pull–out tool and check it. If it has blown, push a new fuse into the clips.
252
a. Look carefully at the fuse. If the thin wire is broken, the fuse has blown. If you are not sure or if it is too dark to see, try replacing the suspected fuse with one of the same value that you know is good.
b. Only install a fuse with the amperage rating designated on the fuse box lid.
If you do not have a spare fuse, in an emergency you can pull out the ”CIG”, ”RADIO NO.1”, ”DOME” or ”HTR” fuse, which may be dispensable for normal driving, and use it if its amperage rating is the same.
If you cannot use one of the same amperage, use one lower than, but as close as possible to, the amperage. If the amperage is lower than that specified, the fuse might blow out again but this does not indicate anything wrong. Be sure to get the correct fuse as soon as possible and return the substitute to its original clips.
Page 26
ELECTRICAL COMPONENTS
It is a good idea to purchase a set of spare fuses and keep them in your vehicle for emergencies.
If the new fuse immediately blows out, there is a problem with the electrical system. Have your Lexus dealer correct it as soon as possible.
CAUTION
Never use a fuse with a higher amperage rating, or any other object, in place of a fuse. This may cause extensive damage and possibly a fire.
CHECKING THE CARTRIDGE TYPE
FUSES
If the headlights or other electrical components do not work and the blade type fuses are O.K., check the cartridge type fuses. If any of the cartridge type fuses are blown, they must be replaced.
253
Page 27
ELECTRICAL COMPONENTS
If there is an overload in the circuits from the battery, the fuses are designed to blow before the entire wiring harness is damaged.
NOTICE
Before replacing the fuses, have the cause of electrical overload determined and repaired by your Lexus dealer .
ADDING WASHER FLUID
If the washer tank becomes nearly empty, add washer fluid.
You may use plain water as washer fluid. However, in cold areas where temperatures range below the freezing point, use washer fluid containing antifreeze. This product is available at your Lexus dealer and most auto parts stores. Follow the manufacturer’s directions for how much to mix with water.
CAUTION
Always use a genuine Lexus fuse or equivalent for replacement. Never install an ordinary wire – even for a temporary fix. This may cause extensive damage and possibly a fire.
254
NOTICE
Do not use engine antifreeze or any other substitute because it may damage your vehicle’s paint.

CHECKING THE HEADLIGHT AIM
(For low beam only)
Before checking the headlight aim:
1. Be sure that the body around the headlight is not deformed.
2. Park the vehicle on a level spot.
3. The driver should stay in the driver’s seat so that the vehicle has its normal load (with the tank full).
4. Bounce the vehicle several times.
ELECTRICAL COMPONENTS
To check the headlight aim, check the vertical and horizontal gauges.
1. Look at the beam angle gauge (vertical movement). The bubble of the gauge should not deviate from the center of the gauge by more than two marks on either side of the gauge.
255
Page 29
ELECTRICAL COMPONENTS
2. Look at the beam angle gauge (horizontal movement). The blue mark should not deviate by more than one mark on either side of the gauge.
If the error is over the value specified above, take the vehicle to your Lexus dealer to adjust the headlight aim.
REPLACING LIGHT BULBS
The illustration on the following pages show the locations of light bulbs. If it is necessary to replace a bulb, take your vehicle to your Lexus dealer as soon as possible. Use bulbs with the bulb numbers and wattage ratings given in the table.
CAUTION
Halogen bulbs have pressurized gas inside and require special handling. They can burst or shatter if scratched or dropped. Hold a bulb only by its plastic or metal case. Do not touch the glass part of a bulb with bare hands.
NOTICE
Only use a bulb of the listed type.

PROTECTING YOUR VEHICLE
FROM CORROSION
Proper care of your Lexus can help ensure long–term corrosion prevention.
The most common causes of corrosion to your vehicle are:
The accumulation of road salt, dirt and moisture in
hard–to–reach areas under the vehicle.
Chipping of paint or undercoating caused by minor
accidents or by stones and gravel.
The following conditions will cause or accelerate corrosion of your vehicle, so it is important to keep your vehicle, particularly the underside, as clean as possible and to repair any damage to paint or protective coatings as soon as possible.
The presence of road salt or dust control chemicals, salt in
the air near the sea coast, industrial air pollution.
High humidity, especially at temperatures just above
freezing point.
Certain parts of your vehicle are wet or damp for an
extended period of time, even though other parts of the vehicle are dry.
Components of the vehicle which are prevented from
quick–drying due to lack of proper ventilation are exposed to high ambient temperature.
To help prevent corrosion on your Lexus, follow these guidelines:
Keep your vehicle clean by regular washing. In addition,
observe the following points. If you drive on salted roads in the winter or if you live near
the ocean, you should hose off the undercarriage at least once a month to minimize corrosion.
High pressure water or steam is effective for cleaning the
vehicle’s underside and wheel housings. Pay particular attention to these areas as it is dif ficult to see all the mud and dirt. It will do more harm than good to simply wet the mud and debris without removing them. The lower edge of doors, rocker panels and frame members have drain holes which should not be allowed to clog with dirt as trapped water in these areas can cause corrosion.
Wash the underside of the vehicle thoroughly when winter
is over. See ”Washing and waxing” on page 262 for more tips. Check the condition of your vehicle’s paint and trim. If you
find any chips or scratches in the paint, touch them up immediately to prevent corrosion from starting. If the chips or scratches have gone through the bare metal, have a qualified body shop make the repair.
261
Page 35
BODY
Check the interior of your vehicle. Water and dirt can
accumulate under the floor mats and could cause corrosion. Occasionally check under the mats to make sure the area is dry. Be particularly careful when transporting chemicals, cleansers, fertilizers, salt, etc. These should be transported in proper containers. If a spill or leak should occur, immediately clean and dry the area.
Use mud shields on your wheels. If you drive on salted or gravel roads, mud shields help protect your vehicle. Full size shields, which come near to the ground as possible, are the best. We recommend that the fittings and the area where the shields are ins t a l l e d b e t r e a t e d to r e s i s t c o r r o s i o n . Your Lexus dealer will be happy to assist in supplying and installing the shields if they are recommended for your area.
Keep your vehicle in a well ventilated garage or a roofed place. Do not park your vehicle in a damp, poorly ventilated garage. If you wash your vehicle in the garage, or
if you drive it in covered with water or snow, your garage may be so damp it will cause corrosion. Even if your garage is heated, a wet vehicle can corrode if the ventilation is poor.
WASHING AND WAXING
Washing your Lexus
Keep your vehicle clean by regular washing.
The following cases may cause weakness to the paint or corrosion to the body and parts. Wash your vehicle as soon as possible.
When driving in a coastal areaWhen driving on a road sprinkled with antifreezeWhen having stuck of coal tar, tree sap, bird droppings an d
carcass of an insect
When driving in the areas where there is a lot of smoke,
soot, dust, iron dust and chemical substance
When the vehicle becomes remarkably dirty with dust and
mud
Hand–washing your Lexus
Work in th e shade and wait until the vehicle body is not hot to the touch.
1. Rinse off loose dirt with a hose. Remove any mud or road salt from the underside of the vehicle or in the wheel wells.
2. Wash with a mild car–wash soap, mixed according to the manufacturer’s instructions. Use a soft cotton mitt and keep it wet by dipping it frequently into the wash water. Do not rub hard – let the soap and water remove the dirt.
262
Page 36
BODY
Plastic wheel ornaments: The plastic wheel ornaments are
damaged easily by organic substances. If any organic substance splashes an ornament, be sure to wash it off with water and check if the ornament is damaged.
CAUTION
Do not attach the heavily damaged plastic wheel ornament. It may fly off the wheel and cause accidents while the vehicle is moving.
Aluminum wheels: Use only a mild soap or neutral detergent. Urethane bumpers and side moldings: Wash carefully . Do
not scrub with abrasive cleaners. The bumper and side molding faces are soft.
Road tar: Remove with turpentine or cleaners that are marked safe for painted surfaces.
NOTICE
Do not use organic substances (gasoline, kerosene, benzine or strong solvents), which may be toxic or cause damage.
3. Rinse thoroughly – dried soap can cause streaking. In hot weather you may need to rinse each section right after you wash it.
4. To prevent water spots, dry the vehicle using a clean soft cotton towel. Do not rub or press hard – you might scratch the paint.
Automatic car wash
NOTICE
To prevent damage to the antenna, make sure it is retracted before driving your vehicle through an automatic car wash.
Your vehicle may be washed in an automatic car wash, but remember that the paint can be scratched by some type of brushes, unfiltered washing water, or the washing process itself. Scratching reduces paint durability and gloss, especially on darker colors. The manager of the car wash should be able to advise you whether the process is safe for the paint on your vehicle.
Waxing your Lexus
Polishing and waxing is recommended to maintain the original beauty of your Lexus’ finish.
Once a month or if the vehicle surface does not repel water well, apply wax.
1. Always wash and dry the vehicle before you begin waxing, even if you are using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become extremely weathered, use a car–cleaning polish, followed by a separate wax. Carefully follow the manufacturer’s instructions and precautions. Be sure to polish and wax the chrome trim as well as the paint.
263
Page 37
BODY
3. Wax the vehicle again when water does not bead but remains on the surface in large patches.
CLEANING THE INTERIOR
CAUTION
Do not wash the vehicle floor with water, or allow water to get onto the floor when cleaning the vehicle interior or exterior. Water may get into audio components or other electrical components above or under the floor carpet (or mat) and cause a malfunction; and it may cause body corrosion.
Leather Interior
The selected leather is used in your Lexus. Due to a leather product, some parts of leather may be rough, uneven or scratched originally.
To keep good appearance, we recommend you to clean it periodically twice a year.
Remove dirt on the leather in the following ways:
1. Wipe it off lightly using a soft cloth (e.g. gauze) dampened with 5% solution of neutral detergent for wool.
2. Wring water from a clean cloth and thoroughly wipe off all traces of detergent with it.
3. Wipe of f the surface of the leather with a dry soft cloth. Allow the leather to dry in a ventilated shaded area. Excess of wet may cause the hardening or shrinking of the leather.
NOTICE
Dirt or sand adhered to the leather may damage the treated surface and cause it to wear earlier. Remove dirt or sand using a vacuum cleaner.
If a stain should fail to come out with a neutral detergent, apply a cleaner that does not contain an organic solvent.
Never use organic substances such as benzine, alcohol or gasoline, or alkaline or acid solutions for cleaning the leather as these could cause discoloring.
Use of a nylon brush or synthetic fiber cloth, etc. may scratch the fine grained surface of the leather.
Mildew may de velop on soiled leather upholstery . Be especially careful to avoid oil spots. T ry to keep your upholstery always clean.
Long exposure to direct sunlight may cause the leather surface to harden and shrink. Keep your vehicle in a shaded area, especially in the summer.
The interior of your vehicle is apt to heat up on hot summer days, so avoid placing on the upholstery items made of vinyl or plastic or containing wax as these tend to stick to leather when warm.
264
Page 38
BODY
Improper cleaning of the leather upholstery could
result in discoloration or staining.
Synthetic Leather Areas (Dash)
The synthetic leather areas may be easily cleaned with a mild soap or detergent and water.
First vacuum over the upholstery to remove loose dirt. Then, using a sponge or soft cloth, apply the soap solution to the synthetic leather. After allowing it to soak in for a few minutes to loosen the dirt, remove the dirt and wipe off the soap with a clean damp cloth. If all the dirt does not come off, repeat the procedure. Commercial foaming–type cleaners are also available which work well. Follow the manufacturer’s instructions.
NOTICE
Do not use solvent, thinner, gasoline or window cleaner on the interior.
Carpets, Windows and Seat Belts
Begin by vacuuming thoroughly to remove as much dirt as possible. Several types of foam cleaners are available; some are in aerosol cans and others are powders or liquids which you mix with water to produce a foam. To shampoo the carpets, use a sponge or brush to apply the foam. Rub in overlapping circles. Do not apply water – the best results are obtained by keeping the carpet as dry as possible. Read the shampoo instructions and follow them closely.
The seat belts may be cleaned with mild soap and water or with lukewarm water.
Use a cloth or sponge. As you are cleaning, check the belts for excessive wear, fraying or cuts.
NOTICE
Use a good foam–type shampoo to clean the carpets.
Do not use dye or bleach on the belts – it may weaken them.
Do not use the belts until they become dry.
The windows may be cleaned with any household window cleaner.
When cleaning the inside of the rear window, be careful not to scratch or damage the heater wires.

FUEL
Fuel type
Y our vehicle must use only unleaded gasoline.
To help prevent gas station mixups, your Lexus has a smaller fuel tank opening. The special nozzle on pumps with unleaded fuel will fit it, but the larger standard nozzle on pumps with leaded gas will not.
At a minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A. and CGSB
3.5–M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the three–way catalytic converter to lose its effectiveness and the emission control system to function improperly. Also, this can increase maintenance costs.
Octane rating
Select premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher for optimum engine performance. However, if such premium type cannot be obtained, you may temporarily use unleaded gasoline with an Octane Rating as low as 87 (Research Octane Number 91).
Use of unleaded fuel with an octane number or rating lower than stated above will cause persistent heavy knocking. If severe, this will lead to engine damage.
If your engine knocks ...
If you detect heavy knocking even when using the recommended fuel, or if you hear steady knocking while holding a steady speed on level roads, consult your Lexus dealer.
However, now and then, you may notice light knocking for a short time while accelerating or driving up hills. This is no cause for concern.
Gasoline containing detergent additives
Lexus recommends the use of gasoline that contains detergent additives to avoid build–up of engine deposits.
However, all gasoline sold in the U.S. contains detergent additives to keep clean and/or clean intake systems.
Quality gasoline
Automotive manufacturers in the U.S., Europe and Japan have developed a specification for quality fuel named World–Wide Fuel Charter (WWFC) that is expected to be applied world wide. The WWFC consists of three categories that depend on required emission levels. In the U.S., category 3 has been adopted. The WWFC improves air quality by providing for better emissions in vehicle fleets, and customer satisfaction through better vehicle performance.
219
Page 46
ENGINE
Cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxygenates such as ethanol or MTBE is available in many areas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended reformulated gasoline. These types of gasoline provide excellent vehicle performance, reduce vehicle emissions, and improve air quality.
Oxygenates in gasoline
Lexus allows the use of oxygenate blended gasoline where the oxygenate content is up to 10% ethanol or 15% MTBE. If you use gasohol in your Lexus, be sure that it has an octane rating no lower than 87.
Lexus does not recommend the use of gasoline containing methanol.
Sulfur in gasoline
If your vehicle is certified to California Emission Regulation, the vehicle is designed to operate on California cleaner burning gasoline (CBG) that contains lower sulfur. If you cannot use California CBG, your emission control system may suffer damage and turn on the Malfunction Indicator Lamp.
If the malfunction is caused by the type of fuel used, repairs may not be covered by your warranty.
Gasoline containing MMT
Some gasoline contain an octane enhancing additive called MMT (Methylcyclopentadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasoline that contains MMT. If fuel containing MMT is used, your emission control system may be adversely affected. The Malfunction Indicator Lamp on the instrument cluster may come on. If this happens, contact your Lexus dealer for service.
Gasoline quality
In a very few cases, you may experience driveability problems caused by the particular gasoline that you are using. If you continue to have unacceptable driveability, try changing gasoline brands. If this does not rectify your problem, then consult your Lexus dealer.
NOTICE
Do not use gasohol other than stated above. It will cause fuel system damage or vehicle performance problems.
If drivability problems are encountered (poor hot starting, vaporizing, engine knock, etc.), discontinue its use.

FACTS ABOUT ENGINE OIL
CONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and cooling the inside of the engine, and plays a major role in maintaining the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some engine oil during normal engine operation. The causes of oil consumption in a normal engine are as follows.
Oil is used to lubricate pistons, piston rings and cylinders.
A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated when the vehicle is decelerating sucks some of this oil into the combustion chamber. This oil as well as some part of t h e o i l film left on the cylinder wall is burned by the high temperature combustion gases during the combustion process.
Oil is also used to lubricate the stems of the intake valves.
Some of this oil is sucked into the combustion chamber
together with the intake air and is burned along with the fuel.
High temperature exhaust gases also burn the oil used to
lubricate the exhaust valve stems.
The amount of engine oil consumed depends on the viscosity of the oil, the quality of the oil and the way the vehicle is driven.
More oil is consumed by high–speed driving and frequent acceleration and deceleration.
A new engine consumes more oil, since its pistons, piston rings and cylinder walls have not become conditioned.
When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.
For example, if a vehicle is used for repeated short trips and consumes a normal amount of oil, the dipstick may not show any drop in the oil level at all, even after 1000 km (600 miles) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed.
The diluting ingredients evaporate out when the vehicle is then driven at high speeds, as on an expressway , making it appear that oil is excessively consumed after driving at high speeds.
221
Page 48
ENGINE
Importance of engine oil level check
One of the most important points in proper vehicle maintenance is to keep the engine oil at the optimum level so that oil function will not be impaired. Therefore, it is essential that the oil level be checked regularly. Lexus recommends that the oil level be checked every time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to serious engine trouble due to insufficient oil.
For detailed information on oil level check, see ”Checking the engine oil level” on page 223.
USED ENGINE OIL
CAUTION
Used engine oil contains potentially harmful
contaminants which may cause skin disorders such as inflammation or skin cancer, so care should be taken to avoid prolonged and repeated contact with it. To remove used engine oil from your skin, wash thoroughly with soap and water.
Do not leave used oil within the reach of children.Dispose of used oil and used oil filters only in a safe
and acceptable manner. Do not dispose of used oil and used oil filters in household trash, in sewers or onto the ground. Call your Lexus dealer or a service station for information concerning recycling or disposal.
222
Page 49
CHECKING THE ENGINE OIL LEVEL
With the engine at operating temperature and turned off, check the oil level on the dipstick.
1. To get a true reading, the vehicle should be on a level spot. After turning off the engine, wait a few minutes for the oil to drain back into the bottom of the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick and push it in as far as it will go, or the reading will not be correct.
ENGINE
4. Pull the dipstick out and look at the oil level on the end. If it is between the full line (full level mark) and the low line (low level mark), it is O.K.
223
Page 50
ENGINE
If the oil level is below or only slightly above the low line (low level mark), add engine oil of the same type as already in the engine.
Remove the oil filler cap and add engine oil a little at a time, checking the dipstick. The approximate quantity of oil needed to fill between the low line (low level mark) and the full line (full level mark) on the dipstick is indicated below for reference.
When the level reaches within the correct range, return the filler cap and turn the cap clockwise until you hear a click.
Oil quantity. L (qt., lmp. qt.) SC400, SC300 – 1.5 (1.6, 1.3)
NOTICE
Avoid overfilling, or the engine could be damaged. Check the oil level on the dipstick once again after adding the oil.
224
Page 51
ENGINE
Engine oil selection
Use API SJ, ”Energy–Conserving” multigrade engine oil or ILSAC multigrade engine oil.
Recommended viscosity (SAE):
SAE 5W–30 is the best choice for your vehicle, for good fuel economy, and good starting in cold weather.
If you use SAE 10W–30 engine oil in extremely low temperatures, the en gine may become difficult to start, so SAE 5W–30 engine oil is recommended.
Oil identification marks
Either or both API registered marks are added to some oil containers to help you select the oil you should use.
The API Service Symbol is located anywhere on the outside
of the container.
The top portion of the label shows the oil quality by API
(American Petroleum Institute) designation such as SJ.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W–30. ”Energy–Conserving”, shown
in the lower portion, indicates that the oil has fuel–saving
capabilities. The ILSAC (International Lubricant Standardization and
Approval Committee) Certification Mark is displayed on the
front of the container.
225
Page 52
ENGINE
CHECKING THE ENGINE COOLANT
LEVEL
Look at the see–through coolant reservoir when the engine is cold. The coolant level is satisfactory if it is between the”FULL” and ”LOW” lines on the reservoir. If the level is low, add ethylene–glycol type coolant for a proper corrosion protection of aluminum components.
The coolant level in the reservoir will vary with engine temperature. However, if the level is on or below the ”LOW” line, add coolant. Bring the level up to the ”FULL” line.
Always use ethylene–glycol type coolant for a proper corrosion protection of aluminum components. See information in the next column.
If the coolant level drops within a short time after replenishing, there may be a leak in the system. Visually check the radiator, hoses, engine coolant filler cap, radiator cap and drain cock and water pump.
If you can find no leak, have your Lexus dealer test the cap pressure and check for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not remove the radiator cap when the engine is hot.

Use of improper coolants may damage your engine cooling system. Your coolant must contain ethylene–glycol type coolant for a proper corrosion protection of your engine that contains aluminum components. Use ”Toyota Long Life Coolant” or equivalent.
In addition to preventing freezing and subsequent damage to the engine, this type of coolant will also prevent corrosion. Further supplemental inhibitors or additives are neither needed nor recommended.
Read the coolant container for information on freeze protection. Follow the manufacturer’s directions for how much to mix with plain water (preferably demineralized water or distilled water). The total capacity of the cooling system is given on pages 216 (SC400) and 218 (SC300).
We recommend to use 50% solution for your Lexus, to provide protection down to about –35C (–31F). When it is extremely cold, to provi d e protection down to about –50C (–58F), 60% solution is recommended. Do not use more than 70% solution for better coolant performance.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
CHECKING THE ENGINE FAN
FLUID (SC400 ONLY)
Park the vehicle at a level spot and look at the see–through reservoir. If necessary, add automatic transmission fluid DEXRON
II or III.
227
Page 54
ENGINE
If the fluid is hot (70C – 90C or 158F –194F), the level should be in the ”HOT” range. Similarly, if it is cold (10C – 30C or 50F – 86F), the level should be in the ”COLD” range. If the level is at the low side of either range, add automatic transmission fluid DEXRON the range.
II or III to bring the level within
SPARK PLUGS

DO–IT–YOURSELF SERVICE
PRECAUTIONS
If you perform maintenance yourself, be sure to follow the correct procedure given in this Section.
You should be aware that improper or incomplete servicing may result in operating problems.
Performing do–it–yourself maintenance during the warranty period may affect your warranty coverage. Read the separate Lexus Warranty statement for details and suggestions.
This Section gives instructions only for those items that are relatively easy for an owner to perform. As explained in Section 5, there are still a number of items that must be performed by a qualified technician with special tools.
For information on tools and parts for do–it–yourself maintenance, see ”Parts and tools” on page 211.
Utmost care should be taken when working on your vehicle to prevent accidental injury . Here are a few precautions that you should be especially careful to observe:
CAUTION
When the engine is running, keep hands, clothing,
and tools away from the moving fan and engine drive belt. (Removing rings, watches, and ties is advisable.)
Right after driving, the engine compartment – the
engine, radiator, exhaust manifold and power steering fluid reservoir, etc. – will be hot. So be careful not to touch them. Oil and other fluids may also be hot.
Do not smoke, cause sparks or allow open flames
near fuel or the battery. Their fumes are flammable.
Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.
Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or other solid supports.
Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or falling material, fluid spray, etc.
NOTICE
Remember that battery and ignition cables carry high currents or voltages. Be careful of accidentally causing a short circuit.
Before closing the engine hood, check to see that you have not forgotten any tools, rags, etc.
Do not drive with the air cleaner removed, or excessive engine wear could result. Also backfiring could cause a fire in the engine compartment.
Do not overfill automatic transmission fluid, or the transmission could be damaged.

MAINTENANCE REQUIREMENTS
Your Lexus vehicle has been designed to have fewer maintenance requirements with longer service intervals to save both your time and money. However, each regular maintenance as well as day–to–day care is more important than ever before to ensure smooth, trouble–free, safe, and economical driving.
It is the owner’s responsibility to make sure the specified maintenance, including general maintenance services, is performed. Note that both the new vehicle and emission control system warranties specify that proper maintenance and care must be performed. See “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for complete warranty information.
General maintenance
General maintenance items are those day–to–day care practices that are important to your vehicle for proper operation. It is the owner’s responsibility to ensure that the general maintenance items are performed regularly.
These checks or inspections can be done either by yourself or your Lexus dealer.
Scheduled maintenance
The scheduled maintenance items listed in the “Owner’s Manual Supplement / Maintenance Schedule” are those required to be serviced at regular intervals.
For details of your maintenance schedule, read the “Owner’s Manual Supplement / Maintenance Schedule”.
It is recommended that only genuine Lexus parts be used for maintenance.
The owner may elect to use non–Lexus supplied parts for replacement purposes without invalidating the emission control system warranty. However, use of replacement parts which are not of equivalent quality may impair the effectiveness of the emission control systems.
You may also elect to have maintenance, replacement, or repair of the emission control devices and system performed by any automotive repair establishment or individual without invalidating this warranty. See “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for complete warranty information.
Where to go for service?
Lexus technicians are well–trained specialists and are kept up to date with the latest service information through technical bulletins, service tips, and in–dealership training programs. They are well informed about the operation of all the systems on your vehicle.
You can be confident that your Lexus dealer’s service department performs the best job to meet the maintenance requirements of your vehicle.

IF YOUR ENGINE STALLS WHILE
DRIVING
If your engine stalls while driving . . . .
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again. If the engine will not start, see ”If your vehicle will not start”.
CAUTION
If the engine is not running, the power assist for the brakes and steering will not work, so steering and braking will be much harder than usual.
IF YOUR VEHICLE WILL NOT
START
(a) Simple checks
Before making these checks, make sure you have followed the correct starting procedure instructions in ”How to start the engine” on page 139 and that you have sufficient fuel. Since your vehicle is equipped with the engine immobiliser system, also check whether the other keys will start the engine. If they work, your key may be broken. Have the key checked at your Lexus dealer. If none of your keys work, the system is possibly broken. Call your Lexus dealer. See ”Keys” on page 10.
If the engine is not turning over or is turning over too slowly –
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the battery is discharged. You may try jump starting. See ”(c) Jump starting” for further instruction.
If the light is O.K., but the engine still will not start, it needs adjustment or repair. Call a Lexus dealer, Roadside Assistance or Customer Service Assistance. (See ”Foreword”.)
NOTICE
Do not pull–or push–start the vehicle. It may damage the vehicle or cause a collision when the engine starts. Also the three–way catalytic converter may overheat and become a fire hazard.
If the engine turns over at its normal speed but will not start –
1. The engine may be flooded because of repeated cranking. See ”(b) Starting a flooded engine” for further instructions.
2. If the engine still will not start, it needs adjustment or repair. Call a Lexus dealer, Roadside Assistance or Customer Service Assistance. (See ”Foreword”.)
179
Page 74
IN CASE OF AN EMERGENCY
(b) Starting a flooded engine
If the engine will not start, your engine may be flooded because of repeated cranking.
If this happens, turn the key to ”START” with the accelerator pedal held down. Continue this operation for 30 seconds and then stop cranking. Then try starting the engine with your foot off the accelerator pedal.
If the engine does not start after 30 seconds of cranking, release the key, wait a few minutes and try again.
If the engine still will not start, it needs adjustment or repair. Call a Lexus dealer, Roadside Assistance or Customer Service Assistance. (See ”Foreword”.)
NOTICE
Do not crank for more than 30 seconds at a time. This may overheat the starter and wiring systems.
(c) Jump starting
To avoid serious personal injury and damage to your vehicle which might result from battery explosion, acid burns, electrical burns, or damaged electronic components, these instructions must be followed precisely.
If you are unsure about how to follow this procedure, we strongly recommend that you seek help from your Lexus dealer, Roadside Assistance or Customer Service Assistance. (See ”Foreword”.)
CAUTION
Batteries contain sulfuric acid which is poisonous
and corrosive. Wear protective safety glasses when jump starting, and avoid spilling acid on your skin, clothing, or vehicle.
If you should accidentally get acid on yourself or in
your eyes, remove any contaminated clothing and flush the affected area with water immediately . Then get immediate medical attention. If possible, continue to apply water with a sponge or cloth while en route to the medical office.
The gas normally produced by a battery will explode
if a flame or spark is brought near. Use only standardized jumper cables and do not smoke or light a match while jump starting.
NOTICE
The battery used for boosting must be 12 V. Do not jump start unless you are sure that the booster battery is correct.
180
Page 75
IN CASE OF AN EMERGENCY
JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make sure the vehicles are not touching. Turn off all unnecessary lights and accessories.
2. If required, remove all the vent plugs from the booster battery . Lay a cloth over the open vents on the booster battery. (This helps reduce the explosion hazard, personal injuries and burns.)
181
Page 76
IN CASE OF AN EMERGENCY
3. If the engine in the vehicle with the booster battery is not running, start it and let it run for about 5 minutes. During jump starting, run the engine at about 2000 rpm with the accelerator pedal lightly depressed.
4. Connect the jumper cables in the exact order shown in the illustration: positive terminal (”+” mark)–to–positive terminal (”+” mark), and negative terminal (”–” mark)–to–engine or body ground. Note that you first connect the positive cable to the discharged battery and then to the booster battery. Next, connect the negative cable to the booster battery and then to a solid, stationary , unpainted metallic point (such as shown in the illustration) away from the battery . Do not connect it to or near any part that moves when the engine is cranked.
CAUTION
When making the connections, to avoid serious injury, do not lean over the battery or accidentally let the jumper cables or clamps touch anything except the correct battery terminals or the ground.
5. Start your engine in the normal way. After starting, run it at about 2000 rpm for several minutes with the accelerator pedal lightly depressed.
6. Carefully disconnect the cables in the exact reverse order: the negative cable and then the positive cable.
7. Carefully dispose of the battery cover cloths which may now contain sulfuric acid.
8. If removed, replace all the battery vent plugs. If the cause of your battery discharging is not apparent (for
example, lights left on), you should have it checked.
IF YOUR VEHICLE OVERHEATS
If your engine coolant temperature gauge indicates overheating, if you experience a loss of power, or if you hear a loud knocking or pinging noise, the engine has probably overheated.
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your emergency flashers. Put the transmission in ”P” and apply the parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there is no sign of steam or coolant. Your engine could have been seriously damaged already. Call your Lexus dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until there is no steam. Escaping steam or coolant is sign of very high pressure.
182
Page 77
IN CASE OF AN EMERGENCY
B: If no steam is coming from your engine:
Leave the engine running and turn off the air conditioning. Check the following.
Is the cooling fan operating?Is the coolant in the acceptable range?Is the engine drive belt O.K.?
CAUTION
When the engine is running, keep hands and clothing
away from the moving fan and engine drive belt.
Do not attempt to remove the radiator cap when the
engine and radiator are hot. Serious injury could result from scalding hot fluid and steam blown out under pressure.
If the cooling fan is not operating or the coolant is not in the acceptable range, turn off the engine and call your Lexus dealer.
If both conditions are O.K., after the engine coolant temperature has cooled to normal, continue driving your vehicle.
If the engine coolant temperature does not cool down, or your vehicle overheats again, have it checked as soon as possible by your Lexus dealer.
IF YOU HAVE A FLAT TIRE
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the road to a safe place – well away from the traffic. A void stopping on the center divider of a highway. Park on a level spot with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set th e p a rking brake and put the transmission in ”P”.
4. Have everyone get out of the vehicle on the side away from traffic.
5. Read the following instructions thoroughly.
CAUTION
When jacking, be sure to observe the following to reduce the possibility of personal injury:
Follow jacking instructions.Do not put any part of your body under a vehicle
supported by a jack. Personal injury may occur.
Do not start or run the engine while your vehicle is
supported by the jack.
Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in ”P”. Block the wheel diagonally opposite to the one being changed if necessary.
183
Page 78
IN CASE OF AN EMERGENCY
Make sure to set the jack properly in the jack point.
Raising the vehicle with jack improperly positioned will damage the vehicle or may allow the vehicle to fall off the jack and cause personal injury.
Never get under the vehicle when the vehicle is
supported by the jack alone.
Use the jack only for lifting your vehicle during wheel
changing.
Do not raise the vehicle with someone in the vehicle.When raising the vehicle, do not put an object on or
under the jack.
Raise the vehicle only high enough to remove and
change the tire.
NOTICE
Do not continue driving with a deflated tire. Driving even a short distance can damage a tire beyond repair.
Changing procedure
1. Get the tool, jack and spare tire.
To prepare yourself for an emergency, you should familiarize yourself with the use of the jack and each tool, and their storage locations.
184
Page 79
IN CASE OF AN EMERGENCY
When removing the jack, turn the joint by hand in the CONTRACT direction until the jack is free. When storing, turn the joint by hand in the EXPAND direction until the jack is firmly secured to prevent it from flying forward during a collision or sudden braking.
Loosen the bolt and remove it. When storing the spare tire, place it with the outer side of the
wheel facing up. Then bolt the tire in place to prevent the tire from flying forward during a collision or sudden braking.
185
Page 80
IN CASE OF AN EMERGENCY
2. Block the wheel diagonally opposite the flat tire to keep the vehicle from rolling when it is jacked up.
When blocking the wheel, place a wheel block in front of the front wheels or behind the rear wheels.
186
3. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle. Turn the wheel nuts counterclockwise to loosen them. To get
maximum leverage, fit the wrench to the nut so that the handle is on the right side, as shown above. Grab the wrench near the end of the handle and pull up on the handle. Be careful that the wrench does not slip off the nut.
Do not remove the nuts yet – just unscrew them about one–half turn.
Page 81
IN CASE OF AN EMERGENCY
4. Position the jack at the jack points as shown.
Make sure the jack is positioned on a level and solid surface.
5. After making sure no one is in the vehicle, raise it high enough so that the spare tire can be installed.
Allow for the fact that you need more ground clearance when putting on the spare tire than when removing the flat tire.
To raise the vehicle, insert the jack handle into the jack (it is a loose fit) and turn it clockwise. As the jack touches the vehicle and begins to lift, double–check that it is properly positioned.
CAUTION
Never get under the vehicle when the vehicle is supported by the jack alone.
187
Page 82
IN CASE OF AN EMERGENCY
6. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.
188
Before putting on the wheel, remove any corrosion on the mounting surfaces with a wire brush or such. Installation of wheels without good metal–to–metal contact at the mounting surface can cause wheel nuts to loosen and eventually cause a wheel to come off while driving.
Page 83
IN CASE OF AN EMERGENCY
7. Reinstall all the wheel nuts finger tight.
Align the holes in the wheel with the bolts. Then lift up the wheel and get at least the top bolt started through its hole. Wiggle the tire and press it back over the other bolts.
Reinstall the wheel nuts and tighten them as much as you can by hand. Press the tire back and see if you can tighten them more.
8. Lower the vehicle completely and tighten the wheel nuts.
Turn the jack handle counterclockwise to lower the vehicle. Use only the wheel nut wrench to tighten the nuts. Do not use
other tools or any additional leverage other than your hands, such as a hammer, pipe or your foot. Make sure the wrench is securely engaged over the nut.
Tighten each nut a little at a time in the order shown. Repeat the process until all the nuts are tight.
CAUTION
When lowering the vehicle, make sure all portions of
your body and all other persons around will not be injured as the vehicle is lowered to the ground.
As soon as possible after changing wheels, have the
wheel nuts tightened by torque wrench at 103 N·m (10.5 kgf·m, 76 ft·lbf.).
189
Page 84
IN CASE OF AN EMERGENCY
9. After changing the wheel, check the air pressure of the replaced tire. Stow all the tools, jack and flat tire securely .
If the pressure of the replaced tire is low, drive slowly to the nearest service station and fill to the correct pressure.
Do not forget to reinstall the tire valve cap as dirt and moisture could get into the valve core and possible cause air leakage. If the cap is missing, put a new one on as soon as possible.
This is the same procedure for changing or rotating your tires.
CAUTION
Before driving, make sure all the tools, jack and flat tire are securely in place in their storage location to reduce the possibility of personal injury during a collision or sudden braking.
IF YOUR VEHICLE NEEDS TO BE
TOWED
If towing is necessary, we recommend you to hav e i t d one by your Lexus dealer or a commercial tow truck service. In consultation with them, have your vehicle towed using either (a) or (b).
(a) Towing with a wheel lift type truck (b) Using a flat bed truck (c) Never tow with a sling type truck
Only when you cannot receive a towing service from a Lexus dealer or commercial tow truck service, tow your vehicle carefully in accordance with the instructions given in ”(d) Emergency towing” on page 194.
Proper equipment will help ensure that your vehicle is not damaged while being towed. Commercial operators are generally aware of the state/provincial and local laws pertaining to towing.
Your vehicle can be damaged if it is towed incorrectly. Although most operators know the correct procedure, it is possible to make a mistake. To avoid damage to your vehicle, make sure the following precautions are observed. If necessary, show this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing, and abide by the state/provincial and local laws. The wheels and axle on the ground must be in good condition. If they are damaged, use a towing dolly.
190
Page 85
IN CASE OF AN EMERGENCY
(a) Towing with a wheel lift type truck
From front
Use a towing dolly under the rear wheels.
NOTICE
Never tow a vehicle with an automatic transmission from the front with rear wheels on the ground, as this may cause serious damage to the transmission.
From rear
Place the ignition key in the ”ACC” position.
NOTICE
Do not tow with the key removed or in the ”LOCK” position, as the steering lock mechanism is not strong enough to hold the front wheels straight.
When lifting wheels, take care to ensure adequate ground clearance for towing at the opposite end of the raised vehicle. Otherwise, the bumper and/or underbody of the towed vehicle will be damaged during towing.

IN CASE OF AN EMERGENCY
(d) Emergency towing
If towing is necessary, we recommend you to have it done by your Lexus dealer or a commercial tow truck service.
If towing service is not available in an emergency, your vehicle may be temporarily towed by a cable or chain secured to the emergency towing eyelet. Use extreme caution when towing the vehicle.
A driver must be in the vehicle to steer it and operate the brakes.
Towing in this manner may be done only on hard–surfaced roads for a short distance and at low speeds. Also, the wheels, axles, drive train, steering and brakes must all be in good condition.
CAUTION
Use extreme caution when towing the vehicle. Avoid sudden starts or erratic driving maneuvers which would place excessive stress on the emergency towing eyelet and towing cable or chain. The eyelet and towing cable or chain may break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifically intended for use in towing vehicles. Securely fasten the cable or chain to the towing eyelet provided.
Before towing, release the parking brake and put the transmission in ”N”. The ignition key must be in ”ACC” (engine off) or ”ON” (engine running).
CAUTION
If the engine is not running, the power assist for the brakes and steering will not work so steering and braking will be much harder than usual.

IF YOU LOSE YOUR KEYS OR
LOCK YOURSELF OUT
Many Lexus dealers can make a new key if you can give them the ke y number. Since your vehicle is equipped with the engine immobiliser system, the dealer will also need your master key.
See the suggestion given in ”Keys” on page 10. If your keys are locked in the vehicle and you cannot get a
duplicate, many Lexus dealers can still open the door for you, using their special tools. If you must break a window to get in, we suggest breaking the smallest side window because it is the least expensive to replace. Be extremely cautious to avoid cuts from the glass.
Even if you lose only one key, contact your Lexus dealer to make a new key . If you lose all your master keys, you cannot make new keys; the whole system must be replaced.

DRIVING TIPS
BREAK–IN PERIOD
Drive gently and avoid high speeds.
Y ou need not follow a break–in schedule with your new Lexus. But following a few simple tips for the first 1600 km (1000 miles) can add to the future economy and long life of your vehicle:
Do not drive over 88 km/h (55 mph).Avoid overrevving. Maintain engine speed between 2000
and 4000 rpm.
Avoid full–throttle starts.Try to avoid hard stops during the first 300 km (200 miles).Do not drive for a long time at any single speed, either fast
or slow.
Do not tow a trailer during the first 800 km (500 miles).
OPERATION IN FOREIGN
COUNTRIES
If you plan to drive your Lexus in another country ... First, comply with the vehicle registration laws. Second, confirm the availability of the correct fuel (unleaded
and minimum octane rating).
TIPS FOR DRIVING IN VARIOUS
CONDITIONS
Always slow down in gusty crosswinds. This will allow you
much better control. Drive slowly onto curbs and, if possible, at a right angle.
Avoid driving onto high, sharp–edged objects and other
road hazards. Failure to do so can lead to severe tire
damage resulting in tire bursts. When parking on a hill, turn the front wheels until they touch
the curb so that the vehicle will not roll. Apply the parking
brake, and place the transmission in ”P”. If necessary, block
the wheels. Washing your vehicle or driving through deep water may get
the brakes wet. To see whether they are wet, check that
there is no traffic near you and then press the pedal lightly.
If you do not feel a normal braking force, the brakes are
probably wet. To dry them, drive the vehicle cautiously while
lightly pressing the brake pedal with the parking brake
applied. If they still do not work safely, pull to the side of the
road and call a Lexus dealer for assistance.
CAUTION
Before driving, make sure the parking brake is fully
released and that the parking brake reminder light is off.
Do not leave your vehicle unattended while the
engine is running.
167
Page 94
DRIVING TIPS
Do not rest your foot on the brake pedal while driving.
It can cause dangerous overheating, needless wear, and poor fuel economy.
To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes excessively, they may overheat and not work properly. See page 151.
Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The abrupt change in engine speed, such as sudden acceleration or engine braking, could cause the vehicle to spin or skid.
Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140 km/h (85 mph) unless your vehicle has high–speed capability tires. Driving over 140 km/h (85 mph) may result in tire failure, loss of control and possible injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle are high–speed capability tires or not before driving at such speeds.
Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer stopping distance, and it may pull to one side when the brakes are applied. Also, the parking brake will not hold the vehicle securely.
WINTER DRIVING TIPS
Make sure you have a proper freeze protection of engine coolant.
Your coolant must contain ethylene–glycol type coolant for a proper corrosion protection of aluminum components. Use ”Toyota Long Life Coolant” or equivalent. See ”Checking the engine coolant level” on page 226 for instructions.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
When it is extremely cold, we recommend to use 60% solution for your Lexus, to provide protection down to about –50C (–58F). Do not use more than 70% solution for better coolant performance.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it must be in top shape to provide enough power for winter starting. Page 248 tells you how to visually inspect the battery. Y our Lexus dealer and most service stations will be pleased to check the battery charge level.
Make sure the engine oil viscosity is suitable for the cold weather.
See page 225 for recommended viscosity. Leaving a heavy summer oil in your vehicle during winter months may cause harder starting. If you are not sure about which oil to use, call your Lexus dealer – they will be pleased to help.
168
Page 95
DRIVING TIPS
Check the electronic ignition system for loose connections or obvious damage.
Keep the door locks from freezing.
Squirt lock de–icer or glycerine into the locks to keep them from freezing.
Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most auto parts stores. Follow the manufacturer’s directions for how much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because it may damage your vehicle’s paint.
Do not use your parking brake when there is a possibility it could freeze.
When parking, put the transmission into ”P” and block the front wheels. Do not use the parking brake, or snow or water accumulated in and around the parking brake mechanism may freeze the parking brake, making it hard to release.
Keep ice and snow from accumulating under the fenders.
Ice and snow built up under your fenders can make steering difficult. During bad winter driving, stop and check under the fenders occasionally.
Depending on where you are driving, we recommend you carry some emergency equipment.
Some of the things you might put in the vehicle are tire chains, window scraper, bag of sand or salt, flares, small shovel, jumper cables, etc.
TRAILER TOWING
Your vehicle is designed primarily as a passenger–carrying vehicle. Towing a trailer will have an adverse effect on handling, performance, braking, durability and driving economy (fuel consumption, etc.). Your safety and satisfaction depend on the proper use of correct equipment and cautious driving habits. For your safety and the safety of others, you must not overload your vehicle or trailer. Lexus warranties do not apply to damage or malfunction caused by towing a trailer for commercial purposes. Ask your local Lexus dealer for further details before towing.
Weight limits
Before towing, make sure the total trailer weight, gross vehicle weight, gross axle weight and trailer tongue load are all within the limits.
The total trailer weight and tongue load can be measured with platform scales found at a highway weighing station, building supply company, trucking company, junk yard, etc.
169
Page 96
DRIVING TIPS
CAUTION
The total trailer weight (trailer weight plus its cargo
load) must not exceed 726 kg (1600 lb.). Exceeding this weight is dangerous.
Trailer hitch assemblies have different weight
capacities established by the hitch manufacturer. Even though the vehicle may be physically capable o f towing a higher weight, the operator must determine the maximum weight rating of the particular hitch assembly and never exceed the maximum weight rating specified for the trailer hitch. Exceeding the maximum weight rating set by the trailer hitch manufacturer can cause an accident resulting in serious personal injuries.
The gross vehicle weight must not exceed the Gross
Vehicle Weight Rating (GVWR) indicated on the Certification Label. The gross vehicle weight is the sum weight of the unloaded vehicle, driver, passengers, luggage, hitch and trailer tongue load. It also includes the weight of any special equipment installed on your vehicle.
The load on either the front or rear axle resulting from
distribution of the gross vehicle weight on both axles must not exceed the Gross Axle Weight Rating (GAWR) listed on the Certification Label.
170
Page 97
The trailer cargo load should be distributed so that
the tongue load is 9 to 11 % of the total trailer weight, not exceeding the maximum of 73 kg (160 lb.).
Tongue load
Total trailer weight
Never load the trailer with more weight in the back
than in the front. About 60 % of the trailer load should be in the front half of the trailer and the remaining 40 % in the rear.
x 100 = 9 to 11%
DRIVING TIPS
Hitches
If you wish to install a trailer hitch, your Lexus dealer should
be consulted. Use only a hitch which is recommended by Lexus dealer
and conforms to the total trailer weight requirement. Follow the directions supplied by the hitch manufacturer.
Lubricate the hitch ball with a light coat of grease. Lexus recommends removing the trailer hitch whenever
you are not towing a trailer to reduce the possibility of
additional damage caused by the hitch if your vehicle is
struck from behind. After removing the hitch, seal any
mounting holes in the vehicle body to prevent entry of
pollutants such as exhaust fumes, dirt, water, etc. Remove the trailer hitch whenever you are not towing a
trailer so that the rear license plate can be seen clearly.
NOTICE
Install the trailer hitch using only the position recommended by your Lexus dealer. Do not install the trailer hitch on the bumper; this may cause body damage.
Do not use axle–mounted hitches as they can cause damage to the axle housing, wheel bearings, wheels or tires.
171
Page 98
DRIVING TIPS
Brakes and safety chains
Lexus recommends trailers with brakes that conform to
any applicable federal and state/provincial regulations.
A safety chain must always be used between the towing
vehicle and the trailer. Leave sufficient slack in the chain for turns. The chain should cross under the trailer tongue to prevent the tongue from dropping to the ground in case it becomes damaged or separated. For correct safety chain procedures, follow the hitch or trailer manufacturer’s recommendations.
CAUTION
If the total trailer weight exceeds 450 kg (1000 lb.),
trailer brakes are required.
Never tap into your vehicle’s hydraulic system as it
will lower its braking effectiveness.
Never tow a trailer without using a safety chain
securely attached to both the trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is possible danger of the trailer wandering over into another lane.
Tires
Ensure that your vehicle’s tires are properly inflated. Adjust
the tire pressure to the recommended cold tire pressure indicated below:
2
SC400, SC300 – Front 220 kPa (2.2 kgf/cm
Rear 220 kPa (2.2 kgf/cm
The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect to the total trailer weight.
or bar, 32 psi)
2
or bar, 32 psi)
Trailer lights
Trailer lights must comply with federal, state/provincial and
local regulations. See your local recreational vehicle dealer or rental agency for the correct type of wiring and relays for your trailer. Check for correct operation of the turn signals and stop lights each time you hitch up. Direct splicing may damage your vehicle’s electrical system and cause a malfunction of your lights.
Break–in schedule
Lexus recommends that you do not tow a tr a il er w it h a n ew
vehicle or a vehicle with any new power train component (engine, transmission, differential, wheel bearing, etc.) for the first 800 km (500 miles) of driving.
172
Page 99
DRIVING TIPS
Maintenance
If you tow a trailer, your vehicle will require more frequent
maintenance due to the additional load. For this information, please refer to the scheduled maintenance information in the “Owner’s Manual Supplement / Maintenance Schedule”.
Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Pre–towing safety check
Check that your vehicle remains level when a loaded or
unloaded trailer is hitched. Do not drive if the vehicle has an abnormal nose–up or nose–down condition, and check for improper tongue load, overload, worn suspension or other possible causes.
Make sure the trailer cargo is securely loaded so that it
cannot shift.
Check that your rear view mirrors conform to any federal,
state/provincial or local regulation. If they do not, install required rear view mirrors appropriate for towing purposes.
Trailer towing tips
When towing a trailer, your vehicle will handle differently than when not towing. The three main causes of vehicle–trailer accidents are driver error, excessive speed and improper trailer loading. Keep these in mind when towing:
Before starting out, check the operation of the lights and all
vehicle–trailer connections. After driving a short distance,
stop and recheck the lights and connections. Practice
turning, stopping and backing with a trailer in an area away
from traffic until you learn the feel. Backing with a trailer is difficult and requires practice. Grip
the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the right
to move the trailer to the right. (This procedure is generally
opposite to that when backing without a trailer.) Also, just
turn the steering wheel a little at a time, avoiding sharp or
prolonged turning. Have someone guide you when backing
to reduce the risk of an accident. Because stopping distance may be increased,
vehicle–to–vehicle distance should be increased when
towing a trailer. For each 16 km/h (10 mph) of speed, allow
at least one vehicle and trailer length between you and the
vehicle ahead. Avoid sudden braking as you may skid,
resulting in jackknifing and loss of control. This is especially
true on wet or slippery surfaces.
173
Page 100
DRIVING TIPS
Avoid jerky starts or sudden acceleration.Avoid jerky steering and sharp turns. The trailer could hit
your vehicle in a tight turn. Slow down before making a turn to avoid the need of sudden braking.
Remember that when making a turn, the trailer wheels will
be closer than the vehicle wheels to the inside of the turn. Therefore, compensate for this by making a larger than normal turning radius with your vehicle.
Crosswinds and rough roads will adversely affect handling
of your vehicle and trailer, causing sway. Pay attention to the rear from time to time to prepare yourself for being passed by large trucks or buses, which may cause your vehicle and trailer to sway . If swaying happens, firmly grip the steering wheel and reduce speed immediately but gradually. Never increase speed. If it is necessary to reduce speed, brake slowly. Steer straight ahead. If you make no extreme correction with the steering or brakes, your vehicle and trailer will stabilize.
Be careful when passing other vehicles. Passing requires
considerable distance. After passing a vehicle, do not forget the length of your trailer and be sure you have plenty of room before changing lanes.
In order to maintain efficient engine braking and electrical
charging perfor mance, do not use overdrive. Transmission must be in the ”4” position (SC400) or in the ”3” position (SC300).
Because of the added load of the trailer, your vehicle’s
engine may overheat on hot days (at temperatures over 30C [85F]) when going up a long or steep grade with a trailer. If the engine coolant temperature gauge indicates overheating, immediately turn off the air conditioning (if in use), pull your vehicle off the road and stop in a safe spot. See ”If your vehicle overheats” on page 182 of this manual.
Always place wheel blocks under both the vehicle and trailer
wheels when parking. Apply the parking brake firmly. Put the transmission in ”P”. Avoid parking on a slope with a trailer, but if it cannot be avoided, do so only after performing the following:
1. Apply the brakes and keep them applied.
2. Have someone place wheel blocks under both the vehicle and trailer wheels.
3. When the wheel blocks are in place, release your brakes slowly until the blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into ”P” and turn off the engine. When restarting out after parking on a slope:
1. With the transmission in ”P” position, start the engine. Be sure to keep the brake pedal depressed.
