CHASSIS
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.
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 eyes and damage painted
surfaces. If fluid gets in your eyes, flush your eyes
with clean water.
NOTICE
If you spill some of the fluid, be sure to wash it off
with water to prevent it from damaging the parts or
paintwork.
223
CHASSIS
CHECKING POWER STEERING
FLUID
Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRONII or III.
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.
If cold O.K. If hot O.K. Add fluid
1. Clean all the 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 DEXRONII or III to bring
the level within the range.
5. After replacing the filler cap, visually check the steering
box case, vane pump and hose connections for leaks or
damage.
224
CHASSIS
CAUTION
!
The reservoir may be hot so be careful not to burn
yourself.
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
The recommended cold tire pressure, 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 220 kPa (2.2 kgf/cm
or bar, 32 psi). 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.
2
225
CHASSIS
High tire pressure produces a harsh ride, handling problems,
excessive wear at the center of the tire tread, and a greater
possibility of tire damage from road hazards.
The following instructions for checking tire pressure should
be observed:
The pressure should be checked only when the tires
are cold. If your vehicle has been parked for at least 3
hours and has not been driven for more than 1.5 km or 1
mile since, you will get an accurate cold tire pressure
reading.
Always use a tire pressure gauge. The appearance of
the tire can be misleading. Besides, tire pressures that are
even just a few pounds off can degrade 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.
ROTATING TIRES
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.
226
CHECKING AND REPLACING TIRES
When to replace your tires
Replace your tires when the tread wear indicators show.
The location of the tread wear indicators is shown by
the marks molded on the sidewall of each tire.
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.).
New tread
Worn tread
Tread wear indicator
CHASSIS
If you have tire damage such as cuts, splits, cracks deep
enough to expose the fabric, or bulges indicating
internal damage, the tire should be replaced.
If a tire often goes flat or cannot be properly repaired due to
the size or location of a cut or other damage, it should be
replaced. If you are not sure, consult with your Lexus dealer.
If an air loss occurs while driving, do not continue driving with
a deflated tire. Driving even a short distance can damage a
tire beyond repair.
Any tires which are over 6 years old must be checked by
a qualified technician even if damage is not obvious.
Tires deteriorate with age even if they have never or seldom
been used.
This also applies to the spare tire and tires stored for future
use.

Uniform tire quality grading
This information has been prepared in accordan ce with
regulations i s s ued b y the Nationa l H ighwa y Traffic S a fe ty
Administration of the U.S. D epartment of Transporta t i on.
It provides t he purchasers and/or prospective purchasers
of Lexus vehicles with information on uniform tire quality
grading.
You 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 quali ty grades are mol ded on the
sidewall.
Treadwear – The treadwear grade is a comparative rating
based on the w ear r ate of the t ire when t ested under c ontrolled
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 A, B, C – The traction grades from highest to
lowest, are 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 Standards 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 grade of this tire is 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.
228
CHASSIS
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.
INSTALLING SNOW TIRES AND
CHAINS
When to use snow tires or chains
Snow tires or chains are recommended when driving on
snow or ice.
On wet or dry roads, conventional or radial tires provide
better traction than snow or studded tires.
Snow tire selection
If you need snow tires, select the same size,
construction and load capacity as the original tires on
your Lexus.
Do not use tires other than stated above. Since your vehicle
has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded
tires without first checking local regulations for possible
restrictions.
Snow tire installation
Snow tires should be installed on all wheels.
Installing snow tires on the rear wheels only can lead to an
excessive difference in road grip capability between the front
and rear tires which could cause loss of vehicle control.
CAUTION
!
Do not drive with the snow tires incorrectly inflated.
Never drive over 105 k m/h (65 m ph) with any type of
snow ti res.
229
CHASSIS
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.
If wheel covers are used, they will be scratched by the chain
band, so remove the covers before putting on the chains.
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.
REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bends, cracks or
heavy corrosion, the wheel should be replaced.
If you fail to replace damaged wheels, 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.
230
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.
SUSPENSION AND CHASSIS
CAUTION
!
Do no t modify the suspen sion/chassi s with lift kits,
spacers, springs, etc. It can cause dangerous
handli ng characteri stics, resulti ng in loss of con trol .

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.
BODY
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.
253
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.
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 by hand
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.
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 gasoline or strong solvents, which may
be toxic or cause damage.
254
3. Rinse thoroughly – dried soap can cause streaking. In
hot weather you may need to rinse each section right after
you wash it.
4. T o 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.
1. Always wash and dry the vehicle before you begin
waxing, even if you are using a combined cleaner and wax.
2. Use a g ood q uality polish a nd w ax. 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 was the chrome trim as
well as the paint.
BODY
3. Wax the vehicle again when water does not bead but
remains on the surface in large patches.
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 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.
255
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. 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 was as
these tend to stick to leather when warm.
Improper cleaning of the leather upholstery could
result in discoloration or staining.
Synthetic Leather Areas
(Part of door panels)
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.
256
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.
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.

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 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.
If electrolyte gets in 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 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
Terminals
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.
Hold–down clamp
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.
