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.

63sa04
Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRON
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.

if it is hot, the fluid level should be in the ”HOT” range. If the
level is at the low side of the appropriate range, add automatic
transmission fluid DEXRON

To remove the reservoir cap, turn it counterclockwise and lift
up. To reinstall it, turn it clockwise. After replacing the reservoir
cap, visually check the steering box case, vane pump and hose
connections for leaks or damage.

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
63sa03a
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, if so equipped.
The pressure for the spare tire should be 420 kPa (4.2 kgf/cm
or bar, 60 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
309
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
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.
310
CHASSIS
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

Worn tread
Replace the tires when the tread wear indicators show.
The location of the tread wear indicators is shown by the
“TWI” or “
∆” 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.
Your vehicle is equipped with 245/40ZR18 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.
311
CHASSIS
NOTICE
Low profile tire like 245/40ZR18 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 306 or 309.
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.
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.

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. 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.
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.
313
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 mix run–flat tires or standard 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 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.
314
CHASSIS
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.
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 , a s i t 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.
315
CHASSIS
When driving with chains installed, be sure to drive
carefully. Slow down before entering the curves to
avoid losing control of the vehicle. Otherwise an
accident may occur.
REPLACING WHEELS
As you might have difficulty in locating a flat or deflated
tire, a tire pressure warning system should be provided on
the tires of 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.
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 damaged wheels, the tire may slip off the
wheel or 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.
316
CHASSIS
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
When installing aluminum wheels, check that the wheel
nuts are tight after driving your vehicle the first 1600 km
(1000 miles).
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.
317

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.

PROTECTING YOUR VEHICLE
FROM CORROSION
Proper care of your Lexus can help ensure long–term
corrosion prevention.
The most common causes of corrosion to your vehicle
are:
The accumulation of road salt, dirt and moisture in
hard–to–reach areas under the vehicle.
Chipping of paint or undercoating caused by minor
accidents or by stones and gravel.
The following conditions will cause or accelerate
corrosion of your vehicle, so it is important to keep your
vehicle, particularly the underside, as clean as possible
and to repair any damage to paint or protective coatings
as soon as possible.
The presence of road salt or dust control chemicals, salt in
the air near the sea coast, industrial air pollution.
High humidity, especially at temperatures just above
freezing point.
Certain parts of your vehicle are wet or damp for an
extended period of time, even though other parts of the
vehicle are dry.
Components of the vehicle which are prevented from
quick–drying due to lack of proper ventilation are exposed
to high ambient temperature.
To help prevent corrosion on your Lexus, follow these
guidelines:
Keep your vehicle clean by regular washing. In addition,
observe the following points.
If you drive on salted roads in the winter or if you live near
the ocean, you should hose off the undercarriage at least
once a month to minimize corrosion.
High pressure water or steam is effective for cleaning the
vehicle’s underside and wheel housings. Pay particular
attention to these areas as it is dif ficult to see all the mud and
dirt. It will do more harm than good to simply wet the mud
and debris without removing them. The lower edge of
doors, rocker panels and frame members have drain holes
which should not be allowed to clog with dirt as trapped
water in these areas can cause corrosion.
Wash the underside of the vehicle thoroughly when winter
is over.
See ”Washing and waxing” on page 339 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.
338
BODY
Check the interior of your vehicle. Water and dirt can
accumulate under the floor mats and could cause corrosion.
Occasionally check under the mats to make sure the area is
dry. Be particularly careful when transporting chemicals,
cleansers, fertilizers, salt, etc. These should be transported in
proper containers. If a spill or leak should occur, immediately
clean and dry the area.
Keep your vehicle in a well ventilated garage or a roofed
place. Do not park your vehicle in a damp, poorly
ventilated garage. If you wash your vehicle in the garage, or
if you drive it in covered with water or snow, your garage may
be so damp it will cause corrosion. Even if your garage is
heated, a wet vehicle can corrode if the ventilation is poor.
WASHING AND WAXING
Washing your Lexus
Keep your vehicle clean by regular washing.
The following cases may cause weakness to the paint or
corrosion to the body and parts. Wash your vehicle as soon
as possible.
When driving in a coastal area
When driving on a road sprinkled with antifreeze
When having 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
339
BODY
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.

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 surface 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.
CLEANING THE INTERIOR
CAUTION
Be careful not to splash water or spill liquid on the
floor. This may prevent the side airbags from
activating correctly, resulting in serious injury.
Do not wash the vehicle floor with water, or allow
water to get onto the floor when cleaning the vehicle
interior or exterior. Water may get into audio
components or other electrical components above or
under the floor carpet (or mat) and cause a
malfunction; and it may cause body corrosion.
Leather Interior
The selected leather is used in your Lexus. Due to a leather
product, some parts of leather may be rough, uneven or
scratched originally.
To keep good appearance, we recommend you to clean it
periodically twice a year.
Remove dirt on the leather in the following ways:
1. Wipe it off lightly using a soft cloth (e.g. gauze) dampened
with 5% solution of neutral detergent for wool.
2. Wring water from a clean cloth and thoroughly wipe off all
traces of detergent with it.

BODY
3. Wipe of f 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.

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.
BODY
If you have any questions about the cleaning of your
Lexus, your local Lexus dealer will be pleased to answer
them.
