VEHICLE IDENTIFICATION

The vehicle identification number (VIN) is the legal identifier for your vehicle. This number is on the left top of the instrument panel and can be seen through the windshield from outside.

This is the primary identification number for your Lexus. It is used in registering the ownership of your vehicle.

INTRODUCTION

The vehicle identification number (VIN) is also on the Certification Label.

The engine number is stamped on the engine block as shown.

535

INTRODUCTION

THEFT PREVENTION LABELS

(U.S.A. ONLY)

Your new vehicle carries theft prevention labels which are approximately 56 mm (2.20 in.) by 16 mm (0.63 in.).

The purpose of these labels is to reduce the incidence of vehicle thefts by facilitating the tracing and recovery of parts from stolen vehicles. The label is designed so that once it is applied to a surface, any attempt to remove it will result in destroying the integrity of the label. Transferring these labels intact from one part to another will be impossible.

536

NOTICE

You should not attempt to remove the theft prevention labels as it may violate certain state or federal laws.

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 af fect 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 542.

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, other fluids and spark plugs may also be hot.

 If the engine is hot, do not remove the radiator cap or

loosen the drain plugs to prevent burning yourself.

 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.

 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.

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. 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 630 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.

629

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 installed be treated to resist corrosion. 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. W ash 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 substances

 When the vehicle becomes remarkably dirty with dust and

mud

Hand–washing your Lexus

Work in the shade and wait until the vehicle body is not hot to the touch.

1. Rinse off loose dirt with a hose. Remove any mud or road salt from the underside of the vehicle or in the wheel wells.

2. Wash with a mild car–wash soap, mixed according to the manufacturer’s instructions. Use a soft cotton mitt and keep it wet by dipping it frequently into the wash water. Do not rub hard — let the soap and water remove the dirt.

630

BODY

Fuel filler door: Do not apply water (high–pressure car wash,

for example) at or near the fuel tank inlet with the fuel filler door opened. If the water enters the air vent, you may experience trouble with refueling or rough engine idling.

Plastic wheel ornaments: The plastic wheel ornaments are damaged easily by organic substances. If any organic 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.

NOTICE

Do not use organic substances (gasoline, kerosene, benzine or strong solvents), which may be toxic or cause damage.

Aluminum wheels: Use only a mild soap or neutral detergent. Urethane bumpers and side moldings: Wash carefully. Do

not scrub with abrasive cleaners. The bumper and side molding faces are soft.

Road tar: Remove with turpentine or cleaners that are marked safe for painted surfaces.

631

BODY

3. Rinse thoroughly — dried soap can cause streaking. In hot weather you may need to rinse each section right after you wash it.

4. To prevent water spots, dry the vehicle using a clean soft cotton towel. Do not rub or press hard — you might scratch the paint.

Automatic car wash

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

Waxing your Lexus

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

Apply wax once a month or if the vehicle surface does not repel water well.

1. Always wash and dry the vehicle before you begin waxing, even if you are using a combined cleaner and wax.

2. Use a good quality polish and wax. If the finish has become extremely weathered, use a car–cleaning polish, followed by a separate wax. Carefully follow the manufacturer’s instructions and precautions. Be sure to polish and wax the chrome trim as well as the paint.

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

632

BODY

CLEANING THE INTERIOR

CAUTION

Do not wash the vehicle floor with water, or allow water to get onto the floor when cleaning the vehicle interior or exterior. Water may get into audio components or other electrical components above or under the floor carpet (or mat) and cause a malfunction; and it may cause body corrosion.

Leather–trimmed Interior

Remove dirt using a soft cloth dampened with 5% solution of neutral detergent for wool. Then thoroughly wipe off all traces of detergent with a clean damp cloth.

After cleaning or whenever any part of the leather gets wet, dry with a soft clean cloth. Allow the leather to dry in a ventilated shaded area.

633

BODY

NOTICE



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



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



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



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



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



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



Improper cleaning of the leather upholstery could result in discoloration or staining.

634

BODY

Non–leather Trim (Part of door panels)

The non–leather trim may be easily cleaned with a mild soap or detergent and water.

NOTICE

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

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.

635

BODY

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.

636

NOTICE



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



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



Do not use the belts until they become dry.



The windows may be cleaned with any household window cleaner.



Do not apply detergent to or wet the automatic wiper control sensor when cleaning the inside of the windshield.



When cleaning the inside of the quarter and rear windows, be careful not to scratch or damage the wire antennas, heater wires or connectors.

BODY

637

BODY

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

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.

638

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

wipe off any dirt.

RAIN CLEARING MIRRORS

The rear view mirrors have been coated to produce a “rain clearing” effect. This coating causes the raindrops to spread, clearing the driver’s rear view when it rains.

It is sufficient to wash the mirrors with water for day to day care. The rain clearing effect is reduced in drizzle and light rain. In the following cases, the rain clearing effect will be reduced

temporarily, but will gradually recover.

 After wiping dirt off the mirrors  When the mirrors fog up

BODY

 After waxing your vehicle in an automatic car wash  After your vehicle has been parked for a long period in

underground parking lots, etc. where there is no direct

sunlight. If you would like to restore the rain clearing effect to its normal

level immediately in the above cases, wash the mirrors with neutral detergent, then rinse thoroughly.

639

BODY

NOTICE

To maintain the rain clearing ability, and prevent the mirrors from being scratched, observe the following precautions.



Do not use any glass cleaners that contain compounds.



If ice should jam the mirror, do not scrape the mirror. Use a spray de–icer to free the mirror.



Wash off any wax stuck to the mirrors with neutral detergent and rinse thoroughly as any wax on the surface of the mirrors can cause the rain clearing effect to be lost.



Do not use any water repellents as they can destroy the rain clearing effect. If any repellent gets stuck on the surface of the mirrors, wash it off with neutral detergent, then rinse thoroughly.
