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 t he e mission c ontrol s ystem t o f unction 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, occasionally, you may notice light knocking for a short time whi l e accelerating or driving up hills. This is normal and there is no need 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 four 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.

444

Page 6

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.

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.

FUEL PUMP SHUT OFF SYSTEM

The fuel pump shut off system stops supplying fuel to the engine to minimize the risk of fuel leakage when the engine stalls or an airbag inflates upon collision. To restart the engine after the fuel pump shut off system activates, turn the ignition switch to “ACC” or “LOCK” once and start it.

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 that has been damaged and it is in need of repair. In 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.

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.

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.

447

Page 9

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” described below.

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.

CHECKING THE ENGINE OIL LEVEL

62L017c

With the engine at operating temperature and turned off, check the oil level on the dipstick.

1. To get a correct reading, the vehicle should be on 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.

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 difficult 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 509 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.

508

Page 22

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 as 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 covered with water or snow, your garage may be so damp as to 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 area  When driving on a road sprinkled with antifreeze  When exposed to coal tar, tree sap, bird droppings and

carcass of an insect

 When driving in areas where there is a lot of smoke, soot,

dust, iron dust or 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.

509

Page 23

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 to remove it before driving your Lexus 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 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.

510

Page 24

BODY

3. Wax the vehicle again when water does not bead but remains on the surface in large patches.

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–trimmed 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 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.

511

Page 25

BODY

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.

Non–leather trim (Dash and sun visors)

The non–leather trim 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 non–leather trim. 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.

512

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 or connectors.

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.

492

Page 36

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.

 Warning: Battery posts, terminals and related

accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

Checking battery exterior

64L085a



Terminals 2Hold–down clamp

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.

493

Page 37

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 condition

Checking by indicator

64L086a

Check the battery condition by the indicator 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

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.

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.

64L203

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.

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 “D–CIG”, “P RR–IG” or “OBD” 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 to the amperage as possible. 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.



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.

ELECTRICAL COMPONENTS

REPLACING LIGHT BULBS

The illustrations 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.

The tail and stop lights consist of a number of LEDs. If any LED burns out, we recommend you take your vehicle to your Lexus dealer to have the light inspected as soon as possible.

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.

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.

 Do not touch the high voltage socket when the

headlights turn on. 20000 V is momentarily generated and may cause severe injury by an 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.

501

Page 45

ELECTRICAL COMPONENTS

NOTICE

Only use a bulb of the listed type.

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 fogs 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.

CHECKING BRAKE FLUID

63L023a

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. If fluid gets on your hands or in your eyes, flush the affected area with clean water immediately. If you still feel uncomfortable with your hands or eyes, go to the doctor.

NOTICE

If you spill some of the fluid, be sure to wipe it off to prevent it from damaging the parts or paintwork.

Check the fluid level on the through the reservoir. If necessary, add automatic transmission fluid DEXRON 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.

Clean all dirt off the reservoir and look at the fluid level. If the fluid is cold, the level should be in the “COLD” range. Similarly,

if it is hot, the fluid level should be in the “HOT” range. If the level is at the low side of the appropriate range, add automatic transmission fluid DEXRON the range.

To remove the reservoir cap, turn it counterclockwise and lift up. To reinstall it, turn it clockwise. After replacing the reservoir cap, visually check the steering box case, vane pump and hose connections for leaks or damage.

CHECKING TIRE INFLATION

PRESSURE

63L027a

The recommended cold tire inflation pressure, tire size and the combined weight of occupants and cargo (vehicle capacity weight) are described on the tire and loading information label.

465

Page 59

CHASSIS

You should check the tire inflation pressures every two weeks, or at least once a month. And do not forget the spare! The pressure for the spare tire should be the same as that for the standard tire. (See pages 460 through 462.)

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 the tire can be misleading. Besides, tire inflation pressures that are even just a few pounds off can

degrade ride and handling.

 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.

Passengers and luggage weight should be located so

that the vehicle is balanced.

Inspection and adjustment procedure

1. Remove the tire valve cap.

2. Press the tip of the tire pressure gauge to the tire valve.

3. Read the pressure using the graduations of the gauge.

4. In case 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 soapy water to the valve and check for leakage.

466

Page 60

CHASSIS

6. Install the tire valve cap. If a gauge and 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 needs frequent refilling, have it checked by your Lexus dealer.

CAUTION

Keep your tires properly inflated. Otherwise, the following conditions may occur and cause an accident resulting in death or serious injuries.

Low tire pressure (underinflation):

 Excessive wear  Uneven wear  Poor handling  Possibility of blowouts from an overheated tire  Poor sealing of the tire bead  Wheel deformation and/or tire separation  A greater possibility of tire damage from road

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

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.

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.

TYPES OF TIRES

Determine what kind of tires your vehicle is originally equipped with.

1. 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 an d handling performance compared with summer tires in highway driving.

2. 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.

CAUTION

 Do not mix all season and summer tires on your

vehicle as this can cause dangerous handling characteristics, resulting in loss of control.

 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.

CHASSIS

ROTATING TIRES

63L020a

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.

Initial adjustment of the tire pressure warning system is necessary after you have rotated your tires. See “Tire pressure warning system” on page

367.

Worn tread

Replace the tires when the tread wear indicators show. The location of the tread wear indicators is shown by the “TWI” or “ 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.

∆” marks, etc., molded on

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 air loss occurs while driving, do not continue driving. 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 applies also to the spare tire and tires stored for future use.

478

Page 72

CHASSIS

Tire selection

When replacing a tire, use a tire of the same size and construction , and the same or greater maximum load 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 is 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 the Certification Label and sidewall of the tire, see pages 431 and 468.

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.

If you need to change from conventional tires to radial tires or vice versa, replace them as a set.

479

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

Observe the following instruction. Otherwise, an accident may occur resulting in death or serious injuries.

 Do not use snow tires other than the manufacturer’s

recommended size, as this may cause dangerous handling characteristics resulting in loss of control.

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

 Do not drive with the snow tires incorrectly inflated.  Never drive over 120 km/h (75 mph) with any type of

snow tires.

Tire chain selection

Regulations regarding the use of tire chains vary according to location or type of road. Always check 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.

480

Page 74

CHASSIS

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.

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.

If the chains are installed, the tire pressure warning system may not operate properly. See “Tire pressure warning system” on page 367.

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.

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.

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.

481

Page 75

CHASSIS

CAUTION

Observe the following instruction. Otherwise, an accident may occur resulting in death or serious injuries.

 Do not use wheels other than the manufacturer’s

recommended size, as this may cause dangerous handling characteristics resulting in loss of control.

Initial adjustment of the tire pressure warning system is necessary after you have replaced your wheels. See “T ire pressure warning system” on page 367.

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 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.

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 436.

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 leave anything that may burn easily, such as

paper or rags, in the engine compartment.

 Do not smoke, cause sparks or allow open flames

around fuel or the battery. Their fumes are flammable.

 Do not get under your vehicle with just the body jack

supporting it. Always use automotive jack stands or other solid supports.

 Be sure the ignition is off if you work near the electric

cooling fan or radiator grille. With the ignition on, the electric cooling fan may automatically start to run if the air conditioning is on and/or if the coolant temperature is high.

 Use eye protection whenever you work on or under

your vehicle where you may be exposed to flying or falling material, fluid spray, etc.

 Be extremely cautious when working on the battery.

It contains poisonous and corrosive sulfuric acid.

434

Page 82

INTRODUCTION

 Warning: Battery posts, terminals and related

accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

NOTICE



Remember that battery and ignition cables carry high currents or voltages. Be careful of accidentally causing a short circuit.



Add only “Toyota Super Long Life Coolant” or similar high quality ethylene glycol based non–silicate, non–amine, non–nitrite, and non–borate coolant with long–life hybrid organic acid technology to fill the radiator. “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water (for the U.S.A.) or 55% coolant and 45% deionized water (for Canada).

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 / Scheduled Maintenance” are those required to be serviced at regular intervals.

For details of your maintenance schedule, read the “Owner’s Manual Supplement / Scheduled Maintenance”.

It is recommended that only genuine Lexus parts be used for maintenance or for the repair of the emission control system.

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.

MAINTENANCE

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 – reliably and economically.

Your copy of the repair order is proof that all required maintenance has been performed for warranty coverage. If any problems should arise with your vehicle while under warranty, your Lexus dealer will promptly take care of it. Again, be sure to keep a copy of the repair order for any service performed on your Lexus.

What about do–it–yourself maintenance?

Many of the maintenance items are easy to do yourself, if you have a little mechanical ability and a few basic automotive tools. Simple instructions for how to perform them are presented in Section 6.

If you are a skilled do–it–yourself mechanic, the Lexus service manuals are recommended. Please be aware that do–it–yourself maintenance can affect your warranty coverage. See “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for the details.

427

Page 93

MAINTENANCE

CAUTION

Do not continue driving with the vehicle unchecked. It could result in serious vehicle damage and possibly personal injury.

EMISSIONS INSPECTION AND

MAINTENANCE (I/M) PROGRAMS

Some states have vehicle emission inspection programs which include OBD (On–Board Diagnostics) checks.

The OBD system monitors the operation of the emission control system. When the OBD system determines that a problem exist s somewhere in the emission control system, the malfunction indicator lamp comes on. In this case, your vehicle may not pass the I/M test and need to be repaired. Contact your Lexus dealer to service the vehicle.

Even if the malfunction indicator lamp does not come on, your vehicle may not pass the I/M test as readiness codes have not been set in the OBD system.

Readiness codes are automatically set during ordinary driving. However, when the battery is disconnected or run down, the codes are erased. Also, depending on your driving habits, the codes may not be completely set.

Also, if the malfunction indicator lamp had come on recently due to temporary malfunction such as a loose fuel tank cap, your vehicle may not pass the I/M test.

The malfunction indicator lamp will go off after taking several driving trips, but the error code in the OBD system will not be cleared unless about 40 trips or more are taken.

If your vehicle does not pass the I/M test and the malfunction indicator lamp does not come on, contact your Lexus dealer to prepare the vehicle for re–testing.

IN CASE OF AN EMERGENCY

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. Turn the ignition switch to “ACC” or “LOCK”, and 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 302 and that you have sufficient fuel. Since your vehicle is equipped with the engine immobilizer 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, there may be a malfunction in the immobilizer system. 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”.)

397

Page 97

IN CASE OF AN EMERGENCY

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. If the engine will not start, 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”.)

(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 ignition switch to “START” with the accelerator pedal fully depressed. 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 ignition switch, 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.

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”.)

398

Page 98

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.

IN CASE OF AN EMERGENCY



Discharged battery 6Booster battery

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.

399

Page 99

IN CASE OF AN EMERGENCY

When boosting, use the battery of matching or higher quality. Any other battery may be difficult to jump start with.

If jump starting is difficult, charge the battery for several minutes.

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.)

If the booster battery is an extended maintenance interval battery, it is not necessary to remove the vent plugs.

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. Locate positive (+) and negative (–) terminals of each battery . C o n n ect the jumper cables in the exact order (

3 4

) shown in the illustration.

Connect a positive (red) jumper cable clamp to the positive (+) terminal of the discharged battery.

Connect the clamp at the other end of the positive (red) cable to the positive (+) terminal of the booster battery.

Connect a negative (black) cable clamp to the negative (–) terminal of the booster battery.

Connect the clamp at the other end of the negative (black) cable to a solid, stationary, unpainted metallic point (such as shown in the illustration) away from the battery. Do not connect it to o r near any part that moves when the engine is cranked.

1 2

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 at your Lexus dealer.

If the first start attempt is not successful...

Check that t h e c l amp on the jumper cables are tight. Recharge the discharged battery with the jumper cables connected for several minutes and restart your engine in the normal way.

If another attempt is not successful, the battery may be depleted. Have it checked at your Lexus dealer.

Page 100

IN CASE OF AN EMERGENCY

IF YOU CANNOT INCREASE

ENGINE SPEED

If engine speed does not increase when the accelerator pedal is depressed, there may be a problem somewhere in the electronic throttle control system . Move the vehicle to a safe place by means of creeping and call a Lexus dealer for assistance:

1. Depress the brake pedal and shift to the “D” position.

2. Gradually release the brake pedal, and the vehicle starts to move by creeping. After arriving at a safe place, stop the vehicle and call a Lexus dealer for assistance.

CAUTION

 The above method of moving the vehicle is for

emergency. Use it only for moving minimum distances to a safe place.

 Be especially careful to prevent erroneous pedal

operation.

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.
