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 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. 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 443 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.
442
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.
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 covered with water or snow, your garage may be so damp and 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. W ash your vehicle as soon as possible.
When driving in a coastal areaWhen driving on a road sprinkled with antifreezeWhen having coal tar, tree sap, bird droppings and carcass
of an insect
When driving in the areas where there is a lot of smoke,
soot, dust, iron dust and chemical substances
When the vehicle becomes remarkably dirty with dust and
mud
Hand-washing your Lexus
Work in the 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.
443
BODY
Fuel filler door: Do not apply water (high-pressure car wash,
for example) at or near the fuel tank inlet with the fuel filler door opened. If the water enters the air vent, you may experience trouble with refueling or rough engine idling.
Plastic wheel ornaments: The plastic wheel ornaments are damaged easily by organic substances. If any organic substances 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.
NOTICE
Do not use organic substances (gasoline, kerosene, benzine or strong solvents), which may be toxic or cause damage.
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.
444
BODY
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
Your vehicle may be washed in an automatic car wash, but remember that the paint can be scratched by some types 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.
Apply wax once a month or if the vehicle surface does not repel water well.
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.
3. Wax the vehicle again when water does not bead but remains on the surface in large patches.
Windshield washer nozzles: Make sure that the nozzles do not become blocked when waxing. If a nozzle becomes blocked, contact your Lexus dealer to have the vehicle serviced.
445
BODY
NOTICE
If a nozzle becomes blocked, do not try to clear it with a pin or other object. The nozzle will be damaged.
446
BODY
CLEANING THE INTERIOR
CAUTION
Be careful not to splash water or spill liquid on the
floor. This may prevent the side airbags from activating correctly, resulting in serious injury.
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 characteristics of leather products, 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 o f f th e 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.
447
BODY
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 develop 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.
Improper cleaning of the leather upholstery could result in discoloration or staining.
448
BODY
Synthetic Leather Areas (Dash)
The synthetic leather areas may be easily cleaned with a mild soap or detergent and water.
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.
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.
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.
449
BODY
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.
Do not apply detergent to or wet the automatic wiper control sensor when cleaning the inside of the windshield.
When cleaning the inside of the rear window, be careful not to scratch or damage the heater wires or connectors.

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 g e t s i n your hands or eyes, flush them with clean water immediately. If you still feel uncomfortable with your hands or eyes, go to the doctor.

CHECKING TIRE INFLATION
PRESSURE
63E035
The recommended cold tire inflation pressures, tire sizes and the combined weight of occupants and cargo (vehicle capacity weight) are described on page 384 and 441. They are also described on the tire and loading information label as shown.
You should check the tire inflation pressure every two weeks, or at least once a month. And do not forget the spare!
The following instructions for checking tire inflation 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 inflation pressure reading.
Always use a tire pressure gauge. The
appearance of a tire can be misleading. Besides, tire inflation pressures that are even just a few pounds off can degrade handling and ride.
Do not bleed or reduce tire inflation pressure
after driving. It is normal for the tire inflation
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.

Tire pressure gauge
1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire valve.
3. Read the pressure using a graduation of the gauge.
4. In case that the tire inflation pressure is not within the prescribed range, insert the compressed air from the valve. In case of applying too much air, press the center of the valve and release the air to adjust.
5.After completing the tire inflation pressure measurement and adjustment, apply soap water to the valve and check the leakage.
6. Install the tire valve cap.
If the gauge and the air pump are not available, have your vehicle checked by your Lexus dealer.
CAUTION
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.
Incorrect tire inflation pressure may waste fuel, reduce the comfort of driving, reduce tire life and make your vehicle less safe to drive.
If a tire frequently needs refilling, have it checked by your Lexus dealer.

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 car 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
Treadwear — 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.
396
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 grade for this tire 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.

TYPES OF TIRES
Determine what kind of tires your vehicle is originally equipped with.
1. Summer tires
Summer tires are high-speed capability tires best suited to highway driving under dry conditions.
Since summer tires do not have the same traction performance as snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For driving on snow-covered or icy roads, we recommend using snow tires. If installing snow tires, be sure to replace all four tires.
2. All season tires
All season tires are designed to provide better traction in snow and to be adequate for driving in most winter conditions, as well as for use all year round.
All season tires, however, do not have adequate traction performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in acceleration and handling performance compared with summer tires in highway driving.
The details about how to distinguish summer tires from all season tires are described on page 392.
CAUTION
Do not use tires other than the manufacturer’s
designated tires, and never mix tires or wheels of the sizes different from the originals as this could result in loss of control and could cause death or serious injury.
Do not mix summer and all season tires on
your vehicle as this can cause dangerous handling characteristics, resulting in loss of control.
400
CHASSIS
ROTATING TIRES
To equalize tire wear and help extend tire life, Lexus recommends that you rotate your tires according to the maintenance schedule. (For scheduled maintenance information, please refer to the “Owner’s Manual Supplement/Scheduled Maintenance”.) 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 inflation 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.
401
CHASSIS
CHECKING AND REPLACING TIRES
When to replace your tires
1
New tread
3
Worn tread
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 “ marks, etc., molded on the sidewall of 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.
2
Tread wear indicator
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.
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.
402
CHASSIS
Tire selection
When replacing a tire, use a tire of the same size and construction, and the same or greater maximum loads as the originally installed tires.
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.
Check that the maximum load of the replaced tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever greater. As for the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire, and as for the Gross Axle Weight Ratings (GAWR), see the Certification Label. For details about Certification Label and sidewall of the tire, see pages 352 and 392.
CAUTION
Observe the following instructions. Otherwise, an accident may occur resulting in death or serious injuries.
Do not mix radial, bias belted, or bias-ply tires
on your vehicle, as this may cause dangerous handling characteristics resulting in loss of control.
Do not use tires other than the manufacturer’s
recommended size, as this may cause dangerous handling characteristics resulting in loss of control.
403
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 roads, conventional or radial tires provide better traction than snow or studded tires.
Snow tire selection
If you need snow tires, select tires of the same size, construction and load capacity as the originally installed tires.
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.
CAUTION
Do not use snow tires other than the manufacturer’s recommended size, as this may cause dangerous handling characteristics resulting in loss of control. Otherwise, an accident may occur resulting in death or serious injuries.
Snow tire installation
Snow tires should be installed on all wheels.
Installing snow tires on the front 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 to the same pressure as
the original tires.
Never drive over 120 km/h (75 mph) with any type of
snow tires.
404
CHASSIS
Tire chain selection
1
Side chain
2
Cross chain
Use the tire chains of correct size.
For P215/60R16 94V tires, use the following type chains.
mm (in.) A: Diameter of side chain 3 (0.12) B: Width of side chain 10 (0.39) C: Length of side chain 30 (1.18) D: Diameter of cross chain 4 (0.16) E: Width of cross chain 14 (0.55) F: Length of cross chain 25 (0.98)
Regulations regarding the use of tire chains vary according to location or type of road. Always check the local regulations before installing chains.
405
CHASSIS
NOTICE
If the wrong combination of tire and chain is used, the chains could damage the vehicle body.
Chain installation
Install the chains on the front tires as tightly as possible. Do not use tire chains on the rear 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.
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.
When driving with chains installed, be sure to drive
carefully . Slow down before entering curves to avoid losing control of the vehicle. Otherwise an accident may occur.
406
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 a damaged wheel, 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.
CHASSIS
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.
CAUTION
Do not use wheels other than the manufacturer’s recommended size, as this may cause dangerous handling characteristics resulting in loss of control. Otherwise, an accident may occur resulting in death or serious injuries.
ALUMINUM WHEEL PRECAUTIONS
When installing aluminum wheels, check that the wheel nuts
are tight after driving your vehicle the first 1600 km (1000 miles).
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.

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 immediately and get immediate medical
attention. If possible, continue to apply water with a
sponge or cloth while traveling to the medical office.
ELECTRICAL COMPONENTS
421
ELECTRICAL COMPONENTS
If electrolyte gets on your skin, thoroughly wash the
contacted 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.

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.
NOTICE
Never recharge the battery while the engine is running. Also, be sure all accessories are turned off.
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.

427
ELECTRICAL COMPONENTS
2. Make sure the inoperative 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.
428
Good
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 “RAD NO.1”, “RAD NO.2” or “POWER POINT” 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.
Blown
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.

2. Park the vehicle on a level spot.
3. The driver gets into the driver’s seat and puts the vehicle in a state readying for a driving (with a full tank).
4. Bounce the vehicle several times.
Adjusting the vertical aiming
1. Turn the vertical movement adjusting bolt 1 in either direction using a Phillips-head screwdriver. At this time, keep the turning direction and number of turns in mind.
433
ELECTRICAL COMPONENTS
2. Turn the vertical movement adjusting bolt 2 the same number of turns and in the same direction as step 1 using a Phillips-head screwdriver.
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
To prevent burning yourself, do not replace the light
bulbs while they are hot.
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. Vehicles with discharge headlights — Do not touch the high voltage socket when the
headlight turns on. 20000 V is momentarily
generated and may cause severe injury by electric
shock. Do not disassemble, repair or take apart the headlight
bulbs, connector, power supply circuits and rotated
components. Or you may be injured by electric
shocks. Call your dealer when the headlights fail to
work or have to be replaced or disposed of.
434
NOTICE
Only use a bulb of the listed type.
ELECTRICAL COMPONENTS
The inside of the lens of exterior lights such as headlights may temporarily fog up when the lens becomes wet in the rain or in a car wash. This is not a problem because the fogging is caused by the temperature difference between the outside and inside of the lens, just like the windshield fogged up in the rain. However, if there is a large drop of water on the inside of the lens, or if there is water pooled inside the light, contact your Lexus dealer.

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.
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 Octane Rating 87 (Research Octane Number 91) or higher. For improved vehicle performance, the use of premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher is recommended.
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.
Use of unleaded fuel with an Octane Rating or Research Octane Number lower than stated above will cause persistent heavy knocking. If it is 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, occasionally, you may notice light knocking for a short time while accelerating or driving up hills. This is normal and there is no need for concern.
Gasolines containing detergent additives
365
ENGINE
Lexus recommends the use of gasoline that contain detergent additives to avoid build-up of engine deposits.
For further details, ask your Lexus dealer or a local gasoline retailer.
Quality gasoline
Automobile manufacturers in U.S., Europe and Japan have developed a specification for quality fuel named World-W ide Fuel Charter (WWFC) that is expected to be applied world wide. The WWFC consists of four categories that depend on required emission levels. In the U.S., category 4 has been adopted. The WWFC improves air quality by providing for better emissions in vehicle fleets, and customer satisfaction through better vehicle performance.
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.
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.
366
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.
Take care not to spill gasohol during refueling. Gasohol may cause paint damage.

CAUTION
Inspect the ground under the vehicle before restarting the engine. If you find that liquid has leaked onto the ground, it is the fuel system has been damaged and it is in need of repair. I n this case, do not restart the engine.
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 the oil 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.
368
ENGINE
More oil is consumed under driving conditions such as high speeds and frequent acceleration and deceleration.
A new engine consumes more oil, since its pistons, piston rings and cylinder walls have not become conditioned.
Oil consumption: Max. 1.0 L per 1000 km (1.1 qt./600 miles,
0.9 lmp. qt./600 miles)
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.
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 370.
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.
USED ENGINE OIL
369
ENGINE
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.
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 ground. After turning off the engine, wait a few minutes for the oil to drain back into the bottom of the engine.
2. Pull the dipstick out, hold a rag under the end and wipe it clean.
3. Reinsert the dipstick and push it in as far as it will go, or the reading will not be correct.

ENGINE
If the oil level is below or only slightly above the low 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. We recommend that you use a funnel when adding oil. The approximate quantity of oil needed to fill between the low level mark and the 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.
