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.

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.

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.
