NOTICE
Avoid overfilling, or the power steering could be
damaged.
CHECKING TIRE PRESSURE
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 220 kPa (2.2 kgf/cm
2 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.
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.

CHASSIS
213 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.
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 tham 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!
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.
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 ªSº 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.

CHASSIS
215
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 ahve
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.
