: Change automatic transmission fluid only as necessary.
Generally, it is necessary to change automatic transmission
fluid only if your vehicle is driven under one of the Special
Operating Conditions listed in your “Owner’s Manual
Supplement/Scheduled Maintenance”. When changing the
automatic transmission fluid, use only “Toyota Genuine ATF
Type T–IV” (ATF JWS3309 or NWS6500) to aid in assuring
optimum transaxle performance.

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 cap 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. If fluid gets on your hands
or in your eyes, flush the affected area with clean water
immediately. If you still feel uncomfortable with your
hands or eyes, go to the doctor.
419

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

(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.

CHECKING TIRE INFLATION
PRESSURE
63E035
The recommended cold tire inflation pressures,
tire sizes and the combined weight of occupants
and cargo (vehicle capacity weight) are described
on page 417, 418 and 476. They are also
described on the tire and loading information label
as shown.
You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget
the spare!
The following instructions for checking tire
inflation 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 inflation pressure reading.
423
CHASSIS
Always use a tire pressure gauge. The
appearance of a tire can be misleading. Besides,
tire inflation pressures that are even just a few
pounds off can degrade handling and ride.
Do not bleed or reduce tire inflation pressure
after driving. It is normal for the tire inflation
pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be located
so that the vehicle is balanced.
Inspection and adjustment procedure

Tire pressure gauge
1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire
valve.
3. Read the pressure using the graduations of the
gauge.
4. In case the tire inflation pressure is not within the
prescribed range, insert the compressed air from the
valve. In case of applying too much air, press the
center of the valve and release the air to adjust.
424
CHASSIS
5.After completing the tire inflation pressure
measurement and adjustment, apply soapy water to
the valve and check for leakage.
6. Install the tire valve cap.
If a gauge and air pump are not available, have your
vehicle checked by your Lexus dealer.
CAUTION
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.
Incorrect tire inflation pressure may waste fuel, reduce
the comfort of driving, reduce tire life and make your
vehicle less safe to drive.
If a tire frequently needs refilling, have it checked by
your Lexus dealer.
CAUTION
Keep your tires properly inflated. Otherwise, the
following conditions may occur and cause an
accident resulting in death or serious injuries.
Low tire pressure (underinflation) —
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts from an overheated
tire
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road

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 car 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
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.
430
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 grade for 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.

TYPES OF TIRES
Determine what kind of tires your vehicle is originally
equipped with.
1.Summer tires
Summer tires are high–speed capability tires best
suited to highway driving under dry conditions.
Since summer tires do not have the same traction
performance as snow tires, summer tires are
inadequate for driving on snow–covered or icy roads.
For driving on snow–covered or icy roads, we
recommend using snow tires. If installing snow tires,
be sure to replace all four tires.
2.All season tires
All season tires are designed to provide better traction
in snow and to be adequate for driving in most winter
conditions, as well as for use all year round.
All season tires, however, do not have adequate
traction performance compared with snow tires in
heavy or loose snow. Also, all season tires fall short
in acceleration and handling performance compared
with summer tires in highway driving.
The details about how to distinguish summer tires
from all season tires are described on page 426.
CAUTION
Do not use tires other than the manufacturer’s
designated tires, and never mix tires or
wheels of the sizes different from the originals
as this could result in loss of control and
could cause death or serious injury.
Do not mix summer and all season tires on
your vehicle as this can cause dangerous
handling characteristics, resulting in loss of
control.
435
CHASSIS
ROTATING TIRES
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/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 inflation 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.

etc., molded on the sidewall of each tire.
2
Tread wear indicator
∆” marks,
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.
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 air loss occurs while driving, do not continue driving.
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.
437
CHASSIS
This applies also to the spare tire and tires stored
for future use.
Tire selection
When replacing a tire, use a tire of the same size
and construction, and the same or greater
maximum loads as the originally installed tires.
Using any other size or type of tire may seriously
affect handling, ride, speedometer/odometer
calibration, ground clearance, and clearance between
the body and tires or snow chains.
Check that the maximum load of the replaced tire is
greater than 1/2 of the Gross Axle Weight Ratings
(GAWR) of either the front axle or the rear axle,
whichever is greater. As for the maximum load of
the tire, see the load limit at maximum cold tire
inflation pressure mentioned on the sidewall of the tire,
and as for the Gross Axle Weight Ratings (GAWR),
see the Certification Label. For details about
Certification Label and sidewall of the tire, see pages
383 and 426.
CAUTION
Observe the following instructions. Otherwise,
an accident may occur resulting in death or
serious injuries.
Do not mix radial, bias belted, or bias–ply tires
on your vehicle, as this may cause dangerous
handling characteristics resulting in loss of
control.
Do not use tires other than the manufacturer’s
recommended size, as this may cause
dangerous handling characteristics resulting
in loss of control.
438
CHASSIS
INSTALLING SNOW TIRES AND
CHAINS
When to use snow tires or chains
Snow tires or chains are recommended when driving on
snow or ice.
On wet or dry roads, conventional or radial tires provide better
traction than snow or studded tires.
Snow tire selection
If you need snow tires, select tires of the same size,
construction and load capacity as the originally installed
tires.
Do not use tires other than stated above. Since your vehicle
has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires
without first checking local regulations for possible restrictions.
CAUTION
Do not use snow tires other than the manufacturer’s
recommended size, as this may cause dangerous
handling characteristics resulting in loss of control.
Otherwise, an accident may occur resulting in death or
serious injuries.
Snow tire installation
Snow tires should be installed on all wheels.
Installing snow tires on the front 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
Snow tires should be inflated to the same pressure as
the original tires.
Never drive over 120 km/h (75 mph) with any type of
snow tires.

NOTICE
If the wrong combination of tire and chain is used, the
chains could damage the vehicle body.
CHASSIS
Chain installation
Install the chains on the front tires as tightly as possible.
Do not use tire chains on the rear 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.
CAUTION
Do not exceed 50 km/h (30 mph) or the chain
manufacturer’s recommended speed limit,
whichever is lower.
Drive carefully avoiding bumps, holes, and sharp
turns, which may cause the vehicle to bounce.
Avoid sharp turns or locked–wheel braking, as use of
chains may adversely affect vehicle handling.
When driving with chains installed, be sure to drive
carefully . S l o w down before entering curves to avoid
losing control of the vehicle. Otherwise an accident
may occur.
441
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 a damaged wheel, 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.
Wheel selection
When replacing wheels, care should be taken to ensure
that they a r e e q u i v alent 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
Do not use wheels other than the manufacturer’s
recommended size, as this may cause dangerous
handling characteristics resulting in loss of control.
Otherwise, an accident may occur resulting in death or
serious injuries.
