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 cover by hand. Add brake fluid up to the
”MAX” line.
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.
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.

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 (60C
– 80C or 140F – 175F). You may also check the level when the
fluid is cold (about room temperature, 10C – 30C or 50F –
85F) if the engine has not been run for about five hours.

Under the unloaded condition, check the suspension fluid AHC
in the following way.
1. Start the engine and put the vehicle height in the ”LO” (Low)
mode and then ”N” (Normal) mode.
2. Turn off the ignition switch about 30 seconds after the ”N”
(Normal) mode indicator light comes on.
3. Make sure the fluid level is between ”MAX” and ”MIN”.
If the fluid level is lower than ”MIN”, have suspension fluid AHC
filled by your Lexus dealer.

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 220 kPa (2.2 kgf/cm
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, l o w 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.

CHECKING TIRE PRESSURE
397
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 r einstall 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.
63X005
ROTATING TIRES
To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires approximately every
398
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

Worn tread
Replace the 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. I f y o u
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.).
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 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.
T raction 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.
W arning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering
(turning) traction.
T emperature 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 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.
400
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.
CHASSIS
401
CHASSIS
CAUTION
Do not drive with the snow tires incorrectly inflated.
Never drive over 105 km/h (65 mph) with any type of snow
tires.
Tire chain selection
63L009

Side chain 2Cross chain
Use the tire chains of correct size.
For 275/70R16 tires, use the following type chains.
mm (in.)
A: Diameter of side chain 5.0 (0.20)
B: Width of side chain 18.0 (0.71)
C: Length of side chain 46.1 (1.81)
D: Diameter of cross chain 6.0 (0.24)
E: Width of cross chain 22.0 (0.87)
F: Length of cross chain 37.5 (1.48)
402
Regulations regarding the use of tire chains vary according to
location or type of road. Always check the local regulations
before installing 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.
CHASSIS
403
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.
CAUTION
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
Do not modify the suspension/chassis with lift kits, spacers,
springs, etc. It can cause dangerous handling characteristics,
resulting in loss of control.
404
REPORTING SAFETY DEFECTS
FOR U.S. OWNERS

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.
433
BODY
Check the interior of your vehicle. Water and dirt can accumulate
under the floor mats and could cause corrosion. Occasionally check
under the mats to make sure the area is dry. Be particularly careful
when transporting chemicals, cleansers, fertilizers, salt, etc. These
should be transported in proper containers. If a spill or leak should
occur, immediately clean and dry the area.
Use mud shields on your wheels. If you drive on salted or gravel
roads, mud shields help protect your vehicle. Full–size shields,
which come as near to the ground as possible, are the best. We
recommend that the fittings and the area where the shields are
installed be treated to resist corrosion. Your Lexus dealer will be
happy to assist in supplying and installing the shields if they are
recommended for your area.
Keep your vehicle in a well ventilated garage or a roofed place.
Do not park your vehicle in a damp, poorly ventilated garage.
If you wash your vehicle in the garage, or if you drive it 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 are 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.
434
BODY
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.
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.
435
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.
436
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 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
(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.

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.

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.
