MAINTENANCE
383
Vehicle interior
Items listed below should be checked regularly, e.g.
while performing periodic services, cleaning the
vehicle, etc.
Lights
Make sure the headlight, stop lights, tail lights, turn
signal lights, and other lights are working. Check
headlight aim.
Service reminder indicators and warning buzzers
Check that all service reminder indicators and warning
buzzers function properly.
Steering wheel
Check that it has the specified freeplay. Be alert for
changes in steering condition, such as hard steering,
excessive freeplay or strange noise.
Seats
Check that all front seat controls such as seat adjusters,
seatback recliner, etc. operate smoothly. Check that the
head restraints move up and down smoothly and that the
locks hold securely in any latched position.
Seat belts
Check that the seat belt system such as buckles,
retractors and anchors operate properly and smoothly.
Make sure the belt webbing is not cut, frayed, worn or
damaged. Accelerator pedal
Check
the pedal for smooth operation and uneven pedal
effort or catching.
Brake pedal
Check the pedal for smooth operation and the proper
clearance and freeplay. Check the brake booster
function.
Brakes
At a safe place, check that the brakes do not pull to one
side when applied.
Parking brake
Check that the pedal has the proper travel and that, on
a safe incline, your vehicle is held securely with only the
parking brake applied.
Automatic transmission ªParkº mechanism
Check the lock release button of the selector lever for
proper and smooth operation. On a safe incline, check
that your vehicle is held securely with the selector lever
in ªPº position and all brakes released.

CHASSIS
436controlled 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 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.

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 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.
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.

ADDING WASHER FLUID
64E017a
If the washer tank becomes nearly empty, add
washer fluid.
You may use plain water as washer fluid. However, in
cold areas where temperatures range below the
freezing point, use washer fluid containing antifreeze.
This product is available at your Lexus dealer and most
auto parts stores. Follow the manufacturer's directions
for how much to mix with water.
NOTICE
Do not use engine antifreeze or any othersubstitute because it may damage your vehicle'spaint.
