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 f o r a t l east 15 minutes and get immediate

medical attention. If possible, continue to apply

water with a sponge or cloth while traveling to the

medical office.

 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.

Checking by hydrometer

64G003a

Check the battery condition by the hydrometer color.

BLUE – Good condition.

WHITE – Charging necessary . Have the battery checked by your Lexus dealer.

RED – Have the battery checked by your Lexus dealer.

NOTICE

Do not refill the battery with water.

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, be sure all accessories are turned off.

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. Install only a fuse with the amperage rating designated on the fuse box lid.

If you do not have a spare fuse, in an emergency you can pull out the ”CIG”, ”RAD NO.1” 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 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.

CHECKING THE CARTRIDGE TYPE

FUSES

64G019–1



Good 2Melted

If the headlights or other electrical components do not work and the blade type fuses are O.K., check the cartridge type fuses. If any of the cartridge type fuses are blown, they must be replaced.

If there is an overload in the circuits from the battery, the fuses are designed to blow before the entire wiring harness is damaged.

289

ELECTRICAL COMPONENTS

CAUTION

Always use a genuine Lexus fuse or equivalent for replacement. Never install an ordinary wire – even for a temporary fix. This may cause extensive damage and possibly a fire.

NOTICE

Before replacing the fuses, have the cause of electrical overload determined and repaired by your Lexus dealer .

ADDING WASHER FLUID

64G009

If the washer tank becomes nearly empty, add washer fluid.

You may use plain water as washer fluid. However, in cold areas where temperatures range below the freezing point, use washer fluid containing antifreeze. This product is available at your Lexus dealer and most auto parts stores. Follow the manufacturer’s directions for how much to mix with water.

NOTICE

Do not use engine antifreeze or any other substitute because it may damage your vehicle’s paint.

Mark 2Acceptable range

Horizontal movement gauge: The mark should not deviate

by more than one mark to either side of the gauge. If the edge of the lens does not match “0” mark, adjust the lens

using bolt B. If the error is over the value specified above, take the vehicle

to your Lexus dealer to adjust the headlight aim. After adjusting the headlight in the vertical direction, check that

the light has been shifted from the adjusted position in the horizontal direction.

ELECTRICAL COMPONENTS

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

 Do not disassemble, repair or take apart the low beam

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.

 Halogen bulbs have pressurized gas inside and

require special handling. They can burst or shatter if scratched or dropped. Hold a bulb only by its plastic or metal case. Do not touch the glass part of a bulb with bare hands.

NOTICE

Only use a bulb of the listed type.

The inside of the lens of exterior lights such as headlights may temporarily fog up when the lense 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.

PROTECTING YOUR VEHICLE

FROM CORROSION

Proper care of your Lexus can help ensure long–term corrosion prevention.

The most common causes of corrosion to your vehicle are:

 The accumulation of road salt, dirt and moisture in

hard–to–reach areas under the vehicle.

 Chipping of paint or undercoating caused by minor

accidents or by stones and gravel.

The following conditions will cause or accelerate corrosion of your vehicle, so it is important to keep your vehicle, particularly the underside, as clean as possible and to repair any damage to paint or protective coatings as soon as possible.

 The presence of road salt or dust control chemicals, salt in

the air near the sea coast, industrial air pollution.

 High humidity, especially at temperatures just above

freezing point.

 Certain parts of your vehicle are wet or damp for an

extended period of time, even though other parts of the vehicle are dry.

 Components of the vehicle which are prevented from

quick–drying due to lack of proper ventilation are exposed to high ambient temperature.

To help prevent corrosion on your Lexus, follow these guidelines:

Keep your vehicle clean by regular washing. In addition,

observe the following points.  If you drive on salted roads in the winter or if you live near

the ocean, you should hose off the undercarriage at least once a month to minimize corrosion.

 High pressure water or steam is effective for cleaning the

vehicle’s underside and wheel housings. Pay particular attention to these areas as it is dif ficult to see all the mud and dirt. It will do more harm than good to simply wet the mud and debris without removing them. The lower edge of doors, rocker panels and frame members have drain holes which should not be allowed to clog with dirt as trapped water in these areas can cause corrosion.

 Wash the underside of the vehicle thoroughly when winter

is over. See ”Washing and waxing” on page 300 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.

299

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 in covered with water or snow, your garage may be so damp it will cause corrosion. Even if your garage is heated, a wet vehicle can corrode if the ventilation is poor.

WASHING AND WAXING

Washing your Lexus

Keep your vehicle clean by regular washing.

The following cases may cause weakness to the paint or corrosion to the body and parts. Wash your vehicle as soon as possible.

 When driving in a coastal area  When driving on a road sprinkled with antifreeze  When 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 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.

300

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

Your vehicle may be washed in an automatic car wash, but remember that the paint can be scratched by some type of brushes, unfiltered washing water, or the washing process itself. Scratching reduces paint durability and gloss, especially on darker colors. The manager of the car wash should be able to advise you whether the process is safe for the paint on your vehicle.

Waxing your Lexus

Polishing and waxing is recommended to maintain the original beauty of your Lexus’ finish.

Once a month or if the vehicle surface does not repel water well, apply wax.

1. Always wash and dry the vehicle surface 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.

301

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 a leather product, some parts of leather may be rough, uneven or scratched originally.

To keep good appearance, we recommend you to clean it periodically twice a year.

Remove dirt on the leather in the following ways:

1. Wipe it off lightly using a soft cloth (e.g. gauze) dampened with 5% solution of neutral detergent for wool.

2. Wring water from a clean cloth and thoroughly wipe off all traces of detergent with it.

3. Wipe off the surface of the leather with a dry soft cloth. Allow the leather to dry in a ventilated shaded area. Excess of wet may cause the hardening or shrinking of the leather.

NOTICE



Dirt or sand adhered to the leather may damage the treated surface and cause it to wear earlier. Remove dirt or sand using a vacuum cleaner.



If a stain should fail to come out with a neutral detergent, apply a cleaner that does not contain an organic solvent.



Never use organic substances such as benzine, alcohol or gasoline, or alkaline or acid solutions for cleaning the leather as these could cause discoloring.



Use of a nylon brush or synthetic fiber cloth, etc. may scratch the fine grained surface of the leather.



Mildew may de velop on soiled leather upholstery . Be especially careful to avoid oil spots. T ry to keep your upholstery always clean.



Long exposure to direct sunlight may cause the leather surface to harden and shrink. Keep your vehicle in a shaded area, especially in the summer.



The interior of your vehicle is apt to heat up on hot summer days, so avoid placing on the upholstery items made of vinyl or plastic or containing wax as these tend to stick to leather when warm.

302

BODY

Improper cleaning of the leather upholstery could



result in discoloration or staining.

Synthetic Leather Areas (Dash and sun visors)

The synthetic leather areas may be easily cleaned with a mild soap or detergent and water.

First vacuum over the upholstery to remove loose dirt. Then, using a sponge or soft cloth, apply the soap solution to the synthetic leather. After allowing it to soak in for a few minutes to loosen the dirt, remove the dirt and wipe off the soap with a clean damp cloth. If all the dirt does not come off, repeat the procedure. Commercial foaming–type cleaners are also available which work well. Follow the manufacturer’s instructions.

NOTICE

Do not use solvent, thinner, gasoline or window cleaner on the interior.

Carpets, Windows and Seat Belts

Begin by vacuuming thoroughly to remove as much dirt as possible. Several types of foam cleaners are available; some are in aerosol cans and others are powders or liquids which you mix with water to produce a foam. To shampoo the carpets, use a sponge or brush to apply the foam. Rub in overlapping circles. Do not apply water – the best results are obtained by keeping the carpet as dry as possible. Read the shampoo instructions and follow them closely.

The seat belts may be cleaned with mild soap and water or with lukewarm water.

Use a cloth or sponge. As you are cleaning, check the belts for excessive wear, fraying or cuts.

NOTICE



Use a good foam–type shampoo to clean the carpets.



Do not use dye or bleach on the belts – it may weaken them.



Do not use the belts until they become dry.



The windows may be cleaned with any household window cleaner.



When cleaning the inside of the rear window, be careful not to scratch or damage the heater wires.

303

BODY

Air Conditioning Control Panel, Car Audio, Instrument Panel, Console Panel, and Switches

Use a soft damp cloth for cleaning. Soak a clean soft cloth in water or lukewarm water then lightly

wipe off any dirt.

NOTICE



Do not use organic substances (solvents, kerosene, alcohol, gasoline, etc.) or alkaline or acidic solutions. These chemicals can cause discoloring, staining or peeling of the surface.



If you use cleaners or polishing agents, make sure their ingredients do not include the substances mentioned above.



If you use a liquid car freshener, do not spill the liquid onto the vehicle’s interior surfaces. It may contain the ingredients mentioned above. Immediately clean any spill using the method mentioned above.

If you have any questions about the cleaning of your Lexus, your local Lexus dealer will be pleased to answer them.

FUEL

Fuel type

Y our vehicle must use only unleaded gasoline.

To help prevent gas station mixups, your Lexus has a smaller fuel tank opening. The special nozzle on pumps with unleaded fuel will fit it, but the larger standard nozzle on pumps with leaded gas will not.

At a minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A. and CGSB

3.5–M93 in Canada.

NOTICE

Do not use leaded gasoline. Use of leaded gasoline will cause the three–way catalytic converter to lose its effectiveness and the emission control system to function improperly. Also, this can increase maintenance costs.

Octane rating

Select premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher for optimum engine performance. However, if such premium type cannot be obtained, you may temporarily use unleaded gasoline with an Octane Rating as low as 87 (Research Octane Number 91).

Use of unleaded fuel with an octane number or rating lower than stated above will cause persistent heavy knocking. If severe, this will lead to engine damage.

If your engine knocks ...

If you detect heavy knocking even when using the recommended fuel, or if you hear steady knocking while holding a steady speed on level roads, consult your Lexus dealer.

However, now and then, you may notice light knocking for a short time while accelerating or driving up hills. This is no cause for concern.

Gasoline containing detergent additives

Lexus recommends the use of gasoline that contains detergent additives to avoid build–up of engine deposits.

However, all gasoline sold in the U.S. contains detergent additives to keep clean and/or clean intake systems.

Quality gasoline

Automotive manufacturers in the U.S., Europe and Japan have developed a specification for quality fuel named World–Wide Fuel Charter (WWFC) that is expected to be applied world wide. The WWFC consists of three categories that depend on required emission levels. In the U.S., category 3 has been adopted. The WWFC improves air quality by providing for better emissions in vehicle fleets, and customer satisfaction through better vehicle performance.

248

ENGINE

Cleaner burning gasoline

Cleaner burning gasoline, including reformulated gasoline that contains oxygenates such as ethanol or MTBE is available in many areas.

Lexus recommends the use of cleaner burning gasoline and appropriately blended reformulated gasoline. These types of gasoline provide excellent vehicle performance, reduce vehicle emissions, and improve air quality.

Oxygenates in gasoline

Lexus allows the use of oxygenate blended gasoline where the oxygenate content is up to 10% ethanol or 15% MTBE. If you use gasohol in your Lexus, be sure that it has an octane rating no lower than 87.

Lexus does not recommend the use of gasoline containing methanol.

Sulfur in gasoline

If your vehicle is certified to California Emission Regulation, the vehicle is designed to operate on California cleaner burning gasoline (CBG) that contains lower sulfur. If you cannot use California CBG, your emission control system may suffer damage and turn on the Malfunction Indicator Lamp.

If the malfunction is caused by the type of fuel used, repairs may not be covered by your warranty.

Gasoline containing MMT

Some gasoline contain an octane enhancing additive called MMT (Methylcyclopentadienyl Manganese Tricarbonyl).

Lexus does not recommend the use of gasoline that contains MMT. If fuel containing MMT is used, your emission control system may be adversely affected. The Malfunction Indicator Lamp on the instrument cluster may come on. If this happens, contact your Lexus dealer for service.

Gasoline quality

In a very few cases, you may experience driveability problems caused by the particular gasoline that you are using. If you continue to have unacceptable driveability, try changing gasoline brands. If this does not rectify your problem, then consult your Lexus dealer.

249

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.

Fuel tank capacity

75 L (19.8 gal., 16.5 lmp.gal.)

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 t h e o i l film left on the cylinder wall is burned by the high temperature combustion gases during the combustion process.

 Oil is also used to lubricate the stems of the intake valves.

Some of this oil is sucked into the combustion chamber together with the intake air and is burned along with the fuel. High temperature exhaust gases also burn the oil used to lubricate the exhaust valve stems.

The amount of engine oil consumed depends on the viscosity of the oil, the quality of the oil and the way the vehicle is driven.

More oil is consumed 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.

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.

251

ENGINE

Importance of engine oil level check

One of the most important points in proper vehicle maintenance is to keep the engine oil at the optimum level so that oil function will not be impaired. Therefore, it is essential that the oil level be checked regularly. Lexus recommends that the oil level be checked every time you refuel the vehicle.

NOTICE

Failure to check the oil level regularly could lead to serious engine trouble due to insufficient oil.

For detailed information on oil level check, see ”Checking the engine oil level” on page 253.

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.

252

CHECKING THE ENGINE OIL LEVEL

62G005c



GS430

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

1. To get a true reading, the vehicle should be on a level spot. After turning off the engine, wait a few minutes for the oil to drain back into the bottom of the engine.

2. Pull out the dipstick, and wipe it clean with a rag.

3. Reinsert the dipstick and push it in as far as it will go, or the reading will not be correct.

Reservoir cap 2Upper line 3Lower line

Look at the see–through coolant reservoir when the engine is cold. The coolant level is satisfactory if it is between the”FULL” and ”LOW” lines on the reservoir. If the level is low, add ethylene–glycol type coolant for a proper corrosion protection of aluminum components.

The coolant level in the reservoir will vary with engine temperature. However, if the level is on or below the ”LOW” line, add coolant. Bring the level up to the ”FULL” line.

Always use ethylene–glycol type coolant for a proper corrosion protection of aluminum components. See information in the next column.

255

ENGINE

If the coolant level drops within a short time after replenishing, there may be a leak in the system. Visually check the radiator, hoses, engine coolant filler cap, radiator cap and drain cock and water pump.

If you can find no leak, have your Lexus dealer test the cap pressure and check for leaks in the cooling system.

CAUTION

To prevent burning yourself, do not remove the radiator cap when the engine is hot.

Coolant type selection

Use of improper coolants may damage your engine cooling system. Your coolant must contain ethylene–glycol type coolant for a proper corrosion protection of your engine that contains aluminum components. Use ”Toyota Long Life Coolant” or equivalent.

In addition to preventing freezing and subsequent damage to the engine, this type of coolant will also prevent corrosion. Further supplemental inhibitors or additives are neither needed nor recommended.

Read the coolant container for information on freeze protection. Follow the manufacturer’s directions for how much to mix with plain water (preferably demineralized water or distilled water). The total capacity of the cooling system is given on page 245 or 247.

We recommend to use 50% solution for your Lexus, to provide protection down to about –35C (–31F). When it is extremely cold, to provide protection down to about –50C (–58F), 60% solution is recommended. Do not use more than 70% solution for better coolant performance.

CHECKING BRAKE FLUID

63G002a

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 or when the fluid level in the accumulator is high.

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.

Refilling brake fluid:

1. Turn the ignition switch off.

2. Depress the brake pedal more than 40 times.

3. Remove the reservoir cap by hand. Add brake fluid up to the ”MAX” line.

If you do not follow the procedure above, the reservoir may overflow.

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

CHECKING TIRE PRESSURE

63G005

The recommended cold tire pressures, tire size and the vehicle capacity weight are given on the label.

You should check the tire pressures every two weeks, or at least once a month. And don’t forget the spare! The pressure for the spare tire should be the same with that for the standard tire. (See page 262 or 265.) Incorrect tire pressure can reduce tire life and make your vehicle less safe to drive.

Low tire pressure results in excessive wear, poor handling, reduced fuel economy, and the possibility of blowouts from overheated tires. Also, low tire pressure can cause poor sealing of the tire bead. If the tire pressure is excessively low, there is the possibility of wheel deformation and/or tire separation. So keep your tire pressures at the proper level. If a tire needs frequent refilling, have it checked by your Lexus dealer.

High tire pressure produces a harsh ride, handling problems, excessive wear at the center of the tire tread, and a greater possibility of tire damage from road hazards.

The following instructions for checking tire pressure should be observed:

 The pressure should be checked only when the tires are

cold. If your vehicle has been parked for at least 3 hours

and has not been driven for more than 1.5 km or 1 mile since, you will get an accurate cold tire pressure reading.

 Always use a tire pressure gauge. The appearance of the

tire can be misleading. Besides, tire pressures that are even just a few pounds off can degrade ride and handling.

 Do not bleed or reduce tire pressure after driving. It is

normal for the tire pressure to be higher after driving.

 Never exceed the vehicle capacity weight. The

passengers and luggage weight should be located so that the vehicle is balanced.

 Be sure to reinstall the tire valve caps. Without the valve

caps, dirt or moisture could get into the valve core and cause air leakage. If the caps have been lost, have new ones put on as soon as possible.

271

CHASSIS

ROTATING TIRES

63L008-1

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” or “Maintenance Schedule”.) However, the most appropriate timing for tire rotation may vary according to your driving habits and road surface conditions.

The wheel assemblies must be rotated as illustrated above. When rotating tires, check for uneven wear and damage.

Abnormal wear is usually caused by incorrect tire pressure, improper wheel alignment, out–of balance wheels, or severe braking.

Before storing radial, snow or studded tires, mark the direction of rotation and be sure to install them in the same direction when using them again. Tires should be stored in a cool dry place.

CHASSIS

Vehicles equipped with 235/45ZR17 tires: Your Lexus has

been fitted with specially developed tires which provide exceptional dynamic performance under general road conditions. However your riding comfort may worsen a little and road noise may increase during driving. You may also notice that your tires will wear more rapidly and tire grip performance will be reduced on the snowy and/or icy roads when compared to standard tires. Be sure to have snow tires or tire chains on the snowy and/or icy roads and drive carefully with the speed appropriate for road conditions.

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.

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.

273

CHASSIS

Warning: The traction grade assigned to this tire is based on braking (straight ahead) traction tests and does not include cornering (turning) traction.

Temperature A, B, C – The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

Warning: The temperature grades for this tire are established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

Tire selection

When replacing a tire, use only the same size and construction as originally installed and with the same or greater load capacity.

Using any other size or type of tire may seriously affect handling, ride, speedometer/odometer calibration, ground clearance, and clearance between the body and tires or snow chains.

Do not mix radial, belted, or conventional tires on your vehicle.

Do not use tires or wheels other than the manufacturer’s recommended size.

It can cause dangerous handling characteristics, resulting in loss of control. If you need to change from conventional tires to radial tires or vice versa, replace them as a set.

274

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 the same size, construction and load capacity as the original tires on your Lexus.

Do not use tires other than stated above. Since your vehicle has radial tires as original equipment, make sure your snow tires also have radial construction. Do not install studded tires without first checking local regulations for possible restrictions.

Snow tire installation

Snow tires should be installed on all wheels.

Installing snow tires on the rear wheels only can lead to an excessive difference in road grip capability between the front and rear tires which could cause loss of vehicle control.

CAUTION

 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 the local regulations before installing chains.

Use SAE Class ”S” type radial tire chains, with the exception of radial cable chains or V–bar type chains.

275

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 the curves to avoid losing control of the vehicle. Otherwise an accident may occur.

REPLACING WHEELS

When to replace your wheels

If you have wheel damage such as bends, cracks or heavy corrosion, the wheel should be replaced.

If you fail to replace damaged wheels, the tire may slip off the wheel or cause loss of handling control.

Replacement with used wheels is not recommended as they may have been subjected to rough treatment or high mileage and could fail without warning. Also, bent wheels which have been straightened may have hidden structural damage and therefore should not be used. Never use an inner tube in a leaking wheel which is designed for a tubeless tire.

Wheel selection

When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width, and offset.

Correct replacement wheels are available at your Lexus dealer.

A wheel of a different size or type may adversely affect handling, wheel and bearing life, brake cooling, speedometer/odometer calibration, stopping ability, headlight aim, bumper height, vehicle ground clearance, and tire or snow chain clearance to the body and chassis.

276

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.

SUSPENSION AND CHASSIS

CAUTION

Do not modify the suspension/chassis with lift kits, spacers, springs, etc. It can cause dangerous handling characteristics, resulting in loss of control.

MAINTENANCE

MAINTENANCE REQUIREMENTS

Your Lexus vehicle has been designed for fewer maintenance requirements with longer service intervals to save both your time and money . However, each regular maintenance as well as day–to–day care is more important than ever before to ensure smooth, trouble–free, safe, and economical driving.

It is the owner’s responsibility to make sure the specified maintenance, including general maintenance services, is performed. Note that both the new vehicle and emission control system warranties specify that proper maintenance and care must be performed. See “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for complete warranty information.

General maintenance

General maintenance items are those day–to–day care practices that are important to your vehicle for proper operation. It is the owner’s responsibility to ensure that the general maintenance items are performed regularly.

These checks or inspections can be done either by yourself or your Lexus dealer.

Scheduled maintenance

The scheduled maintenance items listed in the “Owner’s Manual Supplement / Maintenance Schedule” are those required to be serviced at regular intervals.

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

It is recommended that only genuine Lexus parts be used for maintenance.

The owner may elect to use non–Lexus supplied parts for replacement purposes without invalidating the emission control system warranty. However, use of replacement parts which are not of equivalent quality may impair the effectiveness of the emission control systems.

You may also elect to have maintenance, replacement, or repair of the emission control devices and system performed by any automotive repair establishment or individual without invalidating this warranty. See “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for complete warranty information.

228

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.

Your copy of the repair order is proof that all required maintenance has been performed for warranty coverage. And 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 your engine stalls while driving . . . .

1. Reduce your speed gradually, keeping a straight line. Move cautiously off the road to a safe place.

2. Turn on your emergency flashers.

3. Try starting the engine again. If the engine will not start, see ”If your vehicle will not start”.

CAUTION

If the engine is not running, the power assist for the brakes and steering will not work, so steering and braking will be much harder than usual.

IF YOUR VEHICLE WILL NOT

START

(a) Simple checks

Before making these checks, make sure you have followed the correct starting procedure instructions in ”How to start the engine” on page 178 and that you have sufficient fuel. Since your vehicle is equipped with the engine immobiliser system, also check whether the other keys will start the engine. If they work, your key may be broken. Have the key checked at your Lexus dealer. If none of your keys work, the system is possibly broken. Call your Lexus dealer. See ”Keys” on page 8.

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”.)

208

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. 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 key to ”START” with the accelerator pedal held down. Continue this operation for 30 seconds and then stop cranking. Then try starting the engine with your foot off the accelerator pedal.

If the engine does not start after 30 seconds of cranking, release the key, wait a few minutes and try again.

If the engine still will not start, it needs adjustment or repair. Call a Lexus dealer, Roadside Assistance or Customer Service Assistance. (See ”Foreword”.)

NOTICE

Do not crank for more than 30 seconds at a time. This may overheat the starter and wiring systems.

209

IN CASE OF AN EMERGENCY

To avoid serious personal injury and damage to your vehicle which might result from battery explosion, acid burns, electrical burns, or damaged electronic components, these instructions must be followed precisely.

If you are unsure about how to follow this procedure, we strongly recommend that you seek help from your Lexus dealer, Roadside Assistance or Customer Service Assistance. (See ”Foreword”.).

CAUTION

 Batteries contain sulfuric acid which is poisonous

and corrosive. Wear protective safety glasses when jump starting, and avoid spilling acid on your skin, clothing, or vehicle.

 If you should accidentally get acid on yourself or in

your eyes, remove any contaminated clothing and flush the affected area with water immediately . Then get immediate medical attention. If possible, continue to apply water with a sponge or cloth while en route to the medical office.

 The gas normally produced by a battery will explode

if a flame or spark is brought near. Use only standardized jumper cables and do not smoke or light a match while jump starting.

NOTICE

The battery used for boosting must be 12 V. Do not jump start unless you are sure that the booster battery is correct.

1. If the booster battery is installed in another vehicle, make sure the vehicles are not touching. Turn off all unnecessary lights and accessories.

211

IN CASE OF AN EMERGENCY

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 n ow 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.

212

IN CASE OF AN EMERGENCY

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.

B: If no steam is coming from your engine:

Leave the engine running and turn off the air conditioning. Check the following.

 Is the cooling fan operating?  Is the coolant in the acceptable range?  Is the engine drive belt O.K.?

CAUTION

 When the en g ine is running, keep hands and clothing

away from the moving fan and engine drive belt.

 Do not attempt to remove the radiator cap when the

engine and radiator are hot. Serious injury could result from scalding hot fluid and steam blown out under pressure.

If the cooling fan is not operating or the coolant is not in the acceptable range, turn off the engine and call your Lexus dealer.

If both conditions are O.K., after the engine coolant temperature has cooled to normal, continue driving your vehicle.

If the engine coolant temperature does not cool down, or your vehicle overheats again, have it checked as soon as possible by your Lexus dealer.

IF YOU HAVE A FLAT TIRE

1. Reduce your speed gradually, keeping a straight line. Move cautiously off the road to a safe place – well away from the traffic. A void stopping on the center divider of a highway. Park on a level spot with firm ground.

2. Stop the engine and turn on your emergency flashers.

3. Firmly set the parking brake and put the transmission in ”P”.

4. Have everyone get out of the vehicle on the side away from traffic.

5. Read the following instructions thoroughly.

CAUTION

When jacking, be sure to observe the following to reduce the possibility of personal injury:

 Follow jacking instructions.  Do not put any part of your body under a vehicle

supported by a jack. Personal injury may occur.

 Do not start or run the engine while your vehicle is

supported by the jack.

 Stop the vehicle on a level firm ground, firmly set the

parking brake and put the transmission in ”P”. Block the wheel diagonally opposite to the one being changed if necessary.

 Make sure to set the jack properly in the jack point.

Raising the vehicle with jack improperly positioned will damage the vehicle or may allow the vehicle to fall off the jack and cause personal injury.

 Never get under the vehicle when the vehicle is

supported by the jack alone.

 Use the jack only for lifting your vehicle during wheel

changing.

 Do not raise the vehicle with someone in the vehicle.  When raising the vehicle, do not put an object on or

under the jack.

 Raise the vehicle only high enough to remove and

change the tire.

NOTICE

Do not continue driving with a deflated tire. Driving even a short distance can damage a tire and wheel beyond repair.

2. Block the wheel diagonally opposite the flat tire to keep the vehicle from rolling when it is jacked up.

When blocking the wheel, place a wheel block in front of the front wheels or behind the rear wheels.

IN CASE OF AN EMERGENCY

40G004

3. Loosen all the wheel nuts.

Always loosen the wheel nuts before raising the vehicle. Turn the wheel nuts counterclockwise to loosen them. To get

maximum leverage, fit the wrench to the nut so that the handle is on the right side, as shown above. Grab the wrench near the end of the handle and pull up on the handle. Be careful that the wrench does not slip off the nut.

Do not remove the nuts yet – just unscrew them about one–half turn.

40G005–1

4. Position the jack at the jack points as shown.

Make sure the jack is positioned on a level and solid surface.

217

IN CASE OF AN EMERGENCY

40G006

5. After making sure no one is in the vehicle, raise it high enough so that the spare tire can be installed.

Allow for the fact that you need more ground clearance when putting on the spare tire than when removing the flat tire.

To raise the vehicle, insert the jack handle into the jack (it is a loose fit) and turn it clockwise. As the jack touches the vehicle and begins to lift, double–check that it is properly positioned.

CAUTION

Never get under the vehicle when the vehicle is supported by the jack alone.

218

40G007

6. Remove the wheel nuts and remove the flat tire.

Lift the flat tire straight off and put it aside.

40G008

Before putting on the wheel, remove any corrosion on the mounting surfaces with a wire brush or such. Installation of wheels without good metal–to–metal contact at the mounting surface can cause wheel nuts to loosen and eventually cause a wheel to come off while driving.

IN CASE OF AN EMERGENCY

40G009a

7. Reinstall all the wheel nuts finger tight.

Align the holes in the wheel with the bolts. Then lift up the wheel and get at least the top bolt started through its hole. Wiggle the tire and press it back over the other bolts.

Reinstall the wheel nuts and tighten them as much as you can by hand. Press the tire back and see if you can tighten them more.

40G010

8. Lower the vehicle completely and tighten the wheel nuts.

Turn the jack handle counterclockwise to lower the vehicle. Use only the wheel nut wrench to tighten the nuts. Do not use

other tools or any additional leverage other than your hands, such as a hammer, pipe or your foot. Make sure the wrench is securely engaged over the nut.

Tighten each nut a little at a time in the order shown. Repeat the process until all the nuts are tight.

CAUTION

 When lowering the vehicle, make sure all portions of

your body and all other persons around will not be injured as the vehicle is lowered to the ground.

 As soon as possible after changing wheels, have the

wheel nuts tightened by torque wrench at 103 N·m (10.5 kgf·m, 76 ft·lbf.).

219

IN CASE OF AN EMERGENCY

9. After changing the wheel, check the air pressure of the replaced tire. Stow all the tools, jack and flat tire securely.

If the pressure of the replaced tire is low, drive slowly to the nearest service station and fill to the correct pressure.

Do not forget to reinstall the tire valve cap as dirt and moisture could get into the valve core and possible cause air leakage. If the cap is missing, put a new one on as soon as possible.

This is the same procedure for changing or rotating your tires.

CAUTION

 When reinstalling a standard tire, take due care in

handling the ornament to avoid unexpected personal injury.

 Before driving, make sure all the tools, jack and flat

tire are securely in place in their storage location to reduce the possibility of personal injury during a collision or sudden braking.

IF YOUR VEHICLE NEEDS TO BE

TOWED

If towing is necessary, we recommend you to hav e i t d one by your Lexus dealer or a commercial tow truck service. In consultation with them, have your vehicle towed using either (a) or (b).

(a) Towing with a wheel lift type truck (b) Using a flat bed truck (c) Never tow with a sling type truck Only when you cannot receive a towing service from a

Lexus dealer or commercial tow truck service, tow your vehicle carefully in accordance with the instructions given in ”(d) Emergency towing” on page 224.

Proper equipment will help ensure that your vehicle is not damaged while being towed. Commercial operators are generally aware of the state/provincial and local laws pertaining to towing.

Your vehicle can be damaged if it is towed incorrectly. Although most operators know the correct procedure, it is possible to make a mistake. To avoid damage to your vehicle, make sure the following precautions are observed. If necessary, show this page to the tow truck driver.

TOWING PRECAUTIONS:

Use a safety chain system for all towing, and abide by the state/provincial and local laws. The wheels and axle on the ground must be in good condition. If they are damaged, use a towing dolly.

220

IN CASE OF AN EMERGENCY

(a) Towing with a wheel lift type truck

 From front

40G012

Use a towing dolly under the rear wheels.

NOTICE

Never tow a vehicle with an automatic transmission from the front with rear wheels on the ground, as this may cause serious damage to the transmission.

 From rear

40G013a

Place the ignition key in the ”ACC” position.

NOTICE



Do not tow with the key removed or in the ”LOCK” position, as the steering lock mechanism is not strong enough to hold the front wheels straight.



When lifting wheels, take care to ensure adequate ground clearance for towing at the opposite end of the raised vehicle. Otherwise, the bumper and/or underbody of the towed vehicle will be damaged during towing.

221

IN CASE OF AN EMERGENCY

(b) Using a flat bed truck

40G014

 Tie down points

40G022

If your Lexus is transported by a flat bed, it should be tied down at locations A and B as shown above.

IN CASE OF AN EMERGENCY

 Tie down angle

40G015–1

If you use chains or wires to tie down your vehicle, the angles shaded black must be at 45.

40G016–1

NOTICE

Do not tow with a sling type truck, either from the front or rear. This may cause body damage.

223

IN CASE OF AN EMERGENCY

(d) Emergency towing

40G039c

If towing is necessary, we recommend you to have it done by your Lexus dealer or a commercial tow truck service.

If towing service is not available in an emergency, your vehicle may be temporarily towed by a cable or chain secured to the emergency towing eyelet. Use extreme caution when towing the vehicle.

A driver must be in the vehicle to steer it and operate the brakes.

Towing in this manner may be done only on hard–surfaced roads for a short distance and at low speeds. Also, the wheels, axles, drive train, steering and brakes must all be in good condition.

CAUTION

Use extreme caution when towing the vehicle. Avoid sudden starts or erratic driving maneuvers which would place excessive stress on the emergency towing eyelet and towing cable or chain. The eyelet and towing cable or chain may break and cause serious injury or damage.

NOTICE

Use only a cable or chain specifically intended for use in towing vehicles. Securely fasten the cable or chain to the towing eyelet provided.

Before towing, release the parking brake and put the transmission in ”N”. The ignition key must be in ”ACC” (engine off) or ”ON” (engine running).

CAUTION

If the engine is not running, the power assist for the brakes and steering will not work so steering and braking will be much harder than usual.

224

IF YOU CANNOT SHIFT

AUTOMATIC TRANSMISSION

SELECTOR LEVER

40G024b

If you cannot shift the selector lever, use the shift lock override button as follows:

Turn the ignition key to ”LOCK” or ”ACC”. Make sure the parking brake is applied. Pry up the cover with a flat–bladed screwdriver or equivalent.

IN CASE OF AN EMERGENCY

40G025b

Insert your finger, the screwdriver or equivalent into the hole to push down the shift lock override button. You can shift the selector lever while pushing the button.

For your safety, keep the brake pedal depressed.

Be sure to have the system checked by your Lexus dealer as soon as possible.

225

IN CASE OF AN EMERGENCY

IF YOU LOSE YOUR KEYS OR

LOCK YOURSELF OUT

You can purchase a new key at your Lexus dealer if you can give them the key number and master key.

Even if you lose only one key, contact your Lexus dealer to make a new key . If you lose all your master keys, you cannot make new keys; the whole engine immobiliser system must be replaced.

See the suggestion given in “Keys” on page 8. You can use the wireless remote control system with the new

key. Contact your Lexus dealer for detailed information. If your keys are locked in the vehicle and you cannot get a

duplicate, many Lexus dealers can still open the door for you, using their special tools. If you must break a window to get in, we suggest breaking the smallest side window because it is the least expensive to replace. Be extremely cautious to avoid cuts from the glass.
