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 temperature.

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

Keep your vehicle clean by regular washing. In addition,

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

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

 High pressure water or steam is effective for cleaning the

vehicle’s underside and wheel housings. Pay particular
attention to these areas as it is difficult to see all the mud
and dirt. It will do more harm than good to simply wet the
mud and debris without removing 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” 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.

406

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 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 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 stuck of 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 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.

407

BODY

Aluminum wheels: Use only a mild soap or neutral

detergent.
Urethane bumpers and side moldings: W ash 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 gasoline 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 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 does not repel water well, apply
wax.

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.

408

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.

BODY

409

BODY

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 o ff 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

410

BODY

 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. Try 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.

Synthetic Leather Areas (Dash)

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.

411

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.

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.

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.

Precautions

CAUTION

BATTERY PRECAUTIONS
The battery produces flammable and explosive hydrogen gas.
 Do not cause a spark by contacting the battery terminals

with tools.
 Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive sulfuric acid.

 Avoid contact with eyes, skin or clothes.
 Never inhale or swallow electrolyte.
 Wear protective safety glasses when working near the

battery.
 Keep children away from the battery.
EMERGENCY MEASURES
 If electrolyte gets in your eyes, flush your eyes with clean

water for at least 15 minutes and get immediate medical

attention. If possible, continue to apply water with a sponge

or cloth while traveling to the medical office.

380

ELECTRICAL COMPONENTS

 If electrolyte gets on your skin, thoroughly wash the

contact 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 happen to 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 battery exterior

381

ELECTRICAL COMPONENTS

Check the battery for corroded or loose connections,
cracks, or loose hold–down clamps.

1. If the battery is corroded, wash it off with a solution of
warm water and baking soda. Coat the terminals with grease
to prevent further corrosion.

2. If the connections are loose, tighten the clamp bolts –but
do not overtighten.

3. Tighten the hold–down clamp only enough to keep the
battery firmly in place. Overtightening may damage the
battery case.

382

NOTICE

 Make sure the engine and all accessories are turned

off before performing maintenance.

 When checking the battery, remove the ground cable

first and reinstall it last.

 Be careful not to cause a short circuit with tools.
 Take care no solution gets into the battery when

washing it.

ELECTRICAL COMPONENTS

Checking battery fluid

There are 2 types of batteries: maintenance type and
non–maintenance type.

A non–maintenance battery has ”MAINTENANCE FREE
BATTERY” on its top. A maintenance type battery does not
have such indication.

Maintenance type battery

Check the fluid condition by the fluid level lines on the side
of the battery. Or if the battery has a hydrometer on its top,
you can also check the hydrometer.

Non–maintenance battery

Check the battery condition by the hydrometer on the top of
the battery.

(a) Checking by the fluid level lines (Maintenance type
battery only)

383

ELECTRICAL COMPONENTS

The fluid (electrolyte) level must be between the upper
and lower lines.

When checking the fluid level, look at all six cells, not just one
or two.

If the level is lower than the lower line, add distilled water.
(See ”Adding distilled water” on page 386.)

(b) Checking by the hydrometer

384

ELECTRICAL COMPONENTS

Check the battery condition by the hydrometer color.
Maintenance type battery

BLUE – Good condition.
WHITE – Charging necessary. Have the battery checked by

your Lexus dealer.
RED – Add distilled water. (See ”Adding distilled water” on

page 386.)

Non–maintenance type battery

BLUE – Good condition.
WHITE – Charging necessary. Have the battery checked by

your Lexus dealer.
RED – Have the battery checked by your Lexus dealer.

NOTICE

For non–maintenance battery:
Do not refill the battery with water.

385

ELECTRICAL COMPONENTS

Adding distilled water
(Maintenance type battery only)

1. Remove the vent plugs.

2. Add distilled water to cells needing fluid.
If the side of your battery is covered, check the water level by

looking down directly above the cell as illustrated above.

3. Retighten the vent plugs securely.

NOTICE

 Do not overfill the cells. Excess electrolyte could

squirt out of the battery during heavy charging,

causing corrosion or damage.
 Use a cover on the battery for longer life.

386

BATTERY RECHARGING

PRECAUTIONS

During recharging, the battery is producing hydrogen
gas.

Therefore, before recharging:

1. Maintenance type batteries – Remove the vent plugs.

2. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.

3. 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.

 Non–maintenance batteries: Only do a slow charge (5 A or

less). Charging at a quicker rate is dangerous. The battery
may explode causing personal injuries.

Maintenance type batteries: Be sure to remove the vent
plugs before recharging.

ELECTRICAL COMPONENTS

387

ELECTRICAL COMPONENTS

NOTICE

Never recharge the battery while the engine is running.
Also, make sure all accessories are turned off.

CHECKING AND REPLACING

THE BLADE TYPE FUSES

388

1. Turn the ignition switch off and open the fuse box lid.

Determine which fuse may be causing the problem. The lid
of the fuse box shows the name of the circuit for each fuse.

ELECTRICAL COMPONENTS

389

ELECTRICAL COMPONENTS

2. Make sure the inoperative component is turned off.
Pull the suspected fuse straight out with the pull–out tool
and check it. If it has blown, push a new fuse into the clips.

390

ELECTRICAL COMPONENTS

a. Look carefully at the fuse. If the thin wire is broken, the
fuse has blown. If you are not sure or if it is too dark to see,
try replacing the suspected fuse with one of the same value
that you know is good.

b. Only install a fuse with the amperage rating designated on
the fuse box lid.

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

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.

391

ELECTRICAL COMPONENTS

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.

392

CHECKING THE CARTRIDGE

TYPE FUSES

ELECTRICAL COMPONENTS

393

ELECTRICAL COMPONENTS

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.

NOTICE

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

394

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.

ELECTRICAL COMPONENTS

395

ELECTRICAL COMPONENTS

ADDING WASHER FLUID

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.

396

CHECKING THE HEADLIGHT

AIM

(For low beam only)

Before checking the headlight aim:

1. Be sure that the body around the headlight is not deformed.

2. Park the vehicle on a level spot.

3. The driver should stay in the driver’s seat so that the
vehicle has its normal load (with the tank full).

4. Bounce the vehicle several times.

ELECTRICAL COMPONENTS

397

ELECTRICAL COMPONENTS

To check the headlight aim, check the vertical and
horizontal gauges.

1. Look at the beam angle gauge (vertical movement). The
bubble of the gauge should not deviate from the center of the
gauge by more than two marks on either side of the gauge.

398

ELECTRICAL COMPONENTS

2. Look at the beam angle gauge (horizontal movement).
The blue mark should not deviate by more than one mark on
either side of the gauge.

If the error is over the value specified above, take the vehicle
to your Lexus dealer to adjust the headlight aim.

CAUTION

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.

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.

CHECKING BRAKE FLUID

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.

CHASSIS

359

CHASSIS

It is normal for the brake fluid level to go down slightly as the
brake pads wear. So be sure to keep the reservoir filled.

If the reservoir needs frequent refilling, it may indicate a
serious mechanical problem.

If the level is low, add FMVSS No.116 DOT 3 or SAE
J1703 brake fluid to the brake reservoir.

Remove and replace the reservoir cover by hand. Add brake
fluid up to the ”MAX” line.

Use only newly opened brake fluid. Once opened, brake fluid
absorbs moisture from the air, and excess moisture can cause
a dangerous loss of braking efficiency.

CAUTION

Take care when filling the reservoir because brake fluid can
harm your hands or eyes and damage painted surfaces. If
fluid gets in your hands or eyes, flush them with clean water.

NOTICE

 If you spill some of the fluid, be sure to wipe it off to

prevent it from damaging the parts or paintwork.

 For vehicles with traction control system only: Idle

the engine while pouring brake fluid into the reservoir.

CHECKING POWER STEERING

FLUID

CHASSIS

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



II or III.

361

CHASSIS

If the vehicle has been driven around 80 km/h (50 mph) for
20 minutes (a little more in frigid temperatures), the fluid is
hot (60C – 80C or 140F – 175F). You may also check
the level when the fluid is cold (about room temperature,
10C – 30C or 50F – 85F) if the engine has not been run
for about five hours.

1. Clean all dirt off the reservoir.

2. Remove the filler cap by turning it counterclockwise and
wipe the dipstick clean.

3. Reinstall the filler cap.

4. Remove the filler cap again and look at the fluid level. If
the fluid is cold, the level should be in the ”COLD” range on
the dipstick. Similarly, if it is hot, the fluid level should be in
the ”HOT” range. If the level is at the low side of either range,
add automatic transmission fluid DEXRON



II or III to bring

the level within the range.

362

5. After replacing the filler cap, visually check the steering
box case, vane pump and hose connections for leaks or
damage.

CAUTION

The reservoir may be hot so be careful not to burn yourself.

CHASSIS

NOTICE

 Avoid overfilling, or the power steering could be

damaged.

 When adding the power steering fluid, avoid spilling

it. The generator under the power steering reservoir
could be damaged if fluid is spilled on it.

CHECKING TIRE PRESSURE

363

CHASSIS

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 same with that for the standard tire.
(See page 356 or 358.) 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 pressur e should be checked only when the tir es ar e

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 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.

364

ROTATING TIRES

CHASSIS

To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires approximately
every 12000 km (7500 miles). 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

When to replace your tires

365

CHASSIS

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

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.

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.

366

∆” marks molded on the sidewall of each tire.

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.

CHASSIS

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. These quality grades are molded on the
sidewall.

Treadwear – The treadwear grade is a comparative rating

based on the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and a half (1 – 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual
conditions of their use, however , and may depart significantly
from the norm due to variations in driving habits, service
practices and differences in road characteristics and climate.

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

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

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

367

CHASSIS

required by law. W arning: The temperature grade of this tire 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.

368

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 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.

CHASSIS

369

CHASSIS

CAUTION

 Snow tires should be inflated as described below, but never

above the maximum cold tire pressure shown on the tire
sidewall.

or bar, 32 psi)

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.

370

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.

CHASSIS

371

CHASSIS

REPLACING WHEELS

When to replace your wheels

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

If you fail to replace damaged wheels, a tire may slip off a
wheel or they may 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.

ALUMINUM WHEEL

PRECAUTIONS

 After driving your vehicle the first 1600 km (1000 miles),

check that the wheel nuts are tight.

 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.

372

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.

ENGINE

FUEL

Fuel type

Your 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 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.

Gasolines containing detergent additives

Lexus recommends use of gasolines that contain detergent
additives to avoid build–up of engine deposits.

For further details, ask your Lexus dealer or a local gasoline
retailer.

Improved gasolines

The American Automobile Manufacturers Association
(AAMA) has developed a specification of improved
gasolines. The AAMA specification offers optimal fuel
information for better vehicle performance and better
protection of your engine.

Lexus recommends the use of gasolines that meet the AAMA
specification, if available, for improved drivability and
emission control system.

337

ENGINE

Gasolines containing MTBE

Gasolines that contain MTBE (Methyl Tertiary–Butyl
Ether) are available in the market. If you use a gasoline
mixed with MTBE, make certain that it does not contain
more than 15% of MTBE.

Gasolines containing MMT

Some gasolines contain an octane–enhancing additive
called MMT (methylcyclopentadienyl manganese
tricarbonyl).

Lexus does not recommend the use of gasolines that contain
MMT. If fuels containing MMT are 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.

Gasolines containing alcohol

Gasohol is a mixture of gasoline and ethanol. If you use
gasohol in your Lexus, be sure that it is unleaded, has an
octane rating no lower than 87 and does not contain more
than 10% ethanol. Lexus does not recommend the use of
gasolines containing methanol.

If you use gasoline containing methanol, use only gasoline
meeting the requirements above and also containing less than
5% methanol with cosolvents and corrosion inhibitors for
methanol.
