General Precautions

Lexus Integrated Mobile Phone System

1. Use with the engine on.

The Lexus Integrated Mobile Phone System can be used with the engine switch turned ACC or ON. In order to preserve the vehicle battery charge, use this equipment with the engine ON as much as possible. If battery voltage is too low, settings may not be stored normally.

NOTICE

• Only the approved phone models can be used with this system: Consult your Lexus dealer for approved phones.

• This phone utilizes the DSP Echo Canceller in order to minimize noise, such as a howling echo, during hands free cellular use. Please keep in mind that your voice may not be heard clearly depending on your manner of talking or the other party’s environment.

• When both parties are using hands free phones or placing a call in an environment with excessive noise, or if a fellow passenger is using electronic device such as mobile phone, etc., there may be times when the communication link is weak or noise may be heard. The combination of different phone types and lines may cause abnormal noises or drop calls. Please notice that this is not a malfunction of the phone.

CAUTION

• When the vehicle is stopped with the engine running, always apply the parking brake for safety purposes.

• It is recommended when operating the phone and the console display that your vehicle is parked in a safe location and where it is legal to do so.

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 do not dry quickly 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 353 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.

352

Page 37

BODY

Check the interior of your vehicle. Water and dirt can

accumulate under the floor mats and could cause corrosion. Occasionally check under the mats to make sure the area is dry. Be particularly careful when transporting chemicals, cleansers, fertilizers, salt, etc. These should be transported in proper containers. If a spill or leak should occur, immediately clean and dry the area.

Keep your vehicle in a well ventilated garage or a roofed place. Do not park your vehicle in a damp, poorly ventilated garage. If you wash your vehicle in the garage, or

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

WASHING AND WAXING

Washing your Lexus

Keep your vehicle clean by regular washing.

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

 When driving in a coastal area  When driving on a road sprinkled with antifreeze  When having stuck of coal tar, tree sap, bird droppings an d

carcass of an insect

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

soot, dust, iron dust and chemical substances

 When the vehicle becomes remarkably dirty with dust and

mud

Hand–washing your Lexus

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

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

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

65sa01

Spray water on the side windows or top seals from above, at a 45 angle to the ground.

NOTICE

Do not spray water at side windows and top seals in a way which may cause water to enter the vehicle.

Plastic wheel ornaments: The plastic wheel ornaments are

damaged easily by organic substances. If any organic substance splashes an ornament, be sure to wash it off with water and check if the ornament is damaged.

CAUTION

Do not attach the heavily damaged plastic wheel ornament. It may fly off the wheel and cause accidents while the vehicle is moving.

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

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

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

NOTICE

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

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

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

Automatic car wash

NOTICE

To prevent damage to the antenna, make sure it is retracted before driving your vehicle through an automatic car wash.

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

Waxing your Lexus

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

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

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

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

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

CLEANING THE INTERIOR

CAUTION

 Be careful not to splash water or spill liquid on the

floor. This may prevent the side airbags from activating correctly, resulting in serious injury.

 Do not wash the vehicle floor with water, or allow

water to get onto the floor when cleaning the vehicle interior or exterior. Water may get into audio components or other electrical components above or under the floor carpet (or mat) and cause a malfunction; and it may cause body corrosion.

Leather Interior

The selected leather is used in your Lexus. Due to characteristics of leather products, some parts of leather may be rough, uneven or scratched originally.

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

Remove dirt on the leather in the following ways:

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

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

BODY

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 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.

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 or connectors.

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.



The displays of air conditioning control panel and car audio are coated to avoid reflection. If the display becomes dirty, do not use chemicals and detergent. Wipe it off with a dry cloth.

CHECKING BRAKE FLUID

63sa06

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.

NOTICE

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

CAUTION

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

Low tire pressure (underinflation):

 Excessive wear  Uneven wear  Poor handling  Possibility of blowouts from overheated tire.  Poor sealing of the tire bead  Wheel deformation and/or tire separation

High tire pressure (overinflation):

 Poor handling  Excessive wear at the center of the tire tread  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.

 If you cannot adjust the tire pressure when the tires are

cold, add 10 to 20 kPa more to the front tires and rear tires

than the cold tire pressure, but never exceed the maximum cold tire pressure molded on the tire sidewall.

 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 handling and ride.

 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.

CAUTION

The pressure for the compact spare tire must be 420 kPa (4.3 kgf/cm

, 4.2 bar, 60 psi).

ROTATING TIRES

63sa07a

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

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

Abnormal wear is usually caused by incorrect tire 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.

CHECKING AND REPLACING TIRES

323

Page 91

CHASSIS

The tires on your Lexus have built–in tread wear indicators to help you know when the tires need replacement. When the tread depth wears to 1.6 mm (0.06 in.) or less, the indicators will appear. If you can see the indicators in two or more adjacent grooves, the tire should be replaced.

Your vehicle is equipped with 245/40ZR18 or 245/40ZR18 93Y 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. Riding comfort and road noise with the run–flat tires may be a little worse than that with the standard tires. 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 high aspect ratio tires, etc. 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.

NOTICE

Low profile tire like 245/40ZR18 or 245/40ZR18 93Y may have greater damage than usual tires to its tire wheel when receiving impact from the road surface. Therefore, pay attention to the following.



Be sure to use with proper tire pressure. If the tire pressure is low, the tire may have greater damage. For detailed information about tire pressure, see page 318 or 321.



Avoid driving onto high, sharp–edged objects and other road hazards. Failure to do so can lead to severe tire damage.

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.

324

Page 92

CHASSIS

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.

NOTICE



When you purchase new tires, consult your Lexus dealer. If you change from run–flat tires to standard tires, a spare tire should also be purchased.



When the tires must be repaired or replaced, have them repaired or replaced by Lexus dealer or authorized dealer. The tire pressure sensors will be affected by the installation or removal of tires.



When the tires must be replaced, replace the grommets for air pressure sensors as well.

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

Tread wear – 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.

2003 SC430 from May ’03 Prod. (OM24449U)

325

Page 93

CHASSIS

Traction AA, A, B, C – The traction grades, from highest to

lowest, are AA, A, B and C, and they represent the tire’ s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

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

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

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

Tire selection

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

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

CAUTION

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

 Do not mix radial, bias belted, or bias–ply tires on

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

 Do not mix run–flat tires or standard tires on your

vehicle.

 Do not use tires other than the manufacturer’s

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

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

326

Page 94

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 road, conventional or radial tires provide better traction than snow or studded tires.

Snow tire selection

If you need snow tires, select tires of the same size, construction and load capacity as the originally installed tires.

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

CAUTION

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

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

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

Snow tire installation

Snow tires should be installed on all wheels.

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

CAUTION

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

snow tires.

Tire chain selection

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

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.

2003 SC430 from May ’03 Prod. (OM24449U)

Page 95

CHASSIS

NOTICE



When the snow tires must be repaired or replaced, have them repaired or replaced by Lexus dealer or authorized tire dealer. The tire pressure sensor will be affected by the installation or removal of snow tires.



When the snow tires must be replaced, replace the grommets for air pressure sensors as well.



Do not attempt to use a tire chain on the compact spare tire, as it may result in damage to the vehicle as well as the tire.

INFORMATION

If the chains are installed, the air pressure warning system may not operate properly.

CAUTION

 Do not exceed 50 km/h (30 mph) or the chain

manufacturer’s recommended speed limit, whichever is lower.

 Drive carefully avoiding bumps, holes, and sharp

turns, which may cause the vehicle to bounce.

 Avoid sharp turns or locked–wheel braking, as use of

chains may adversely affect vehicle handling.

 When driving with chains installed, be sure to drive

carefully . Slow down before entering curves to avoid losing control of the vehicle. Otherwise an accident may occur.

REPLACING WHEELS

As you might have difficulty in identifying a flat or deflated tire, a tire pressure warning system is provided on this vehicle.

When replacing the wheels, be sure to install air pressure sensors on the wheels.

There are 2 ways to set up the air pressure sensors. a. Remove the sensor from the old wheel and install it to the

new wheel. b. Use a new wheel and sensor.

You have to register an ID code for a new sensor . Up to 2 sets of codes can be registered. As one ID for the originally installed sensor is registered at “MAIN” of the selector switch, use the “2nd” position to register an ID for the new sensor.

You do not need to re–register the ID code for any other replacements. For the use of the originally installed tires, put the selector switch at “MAIN” and for the use of tires purchased later, put the switch at “2nd”. For the sensor selector switch, see page 224.

328

Page 96

CHASSIS

CAUTION

 Have the tires, wheels or sensors replaced and ID

codes registered by Lexus dealer. If you need sensors, purchase from Lexus dealer.

 The use of non–genuine wheels will cause the air

pressure sensor to transmit the electronic code in different manner, resulting in the failure of the system.

When to replace your wheels

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

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

Wheel selection

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

Correct replacement wheels are available at your Lexus dealer.

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

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

CAUTION

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

 Do not use wheels other than the manufacturer’s

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