CAUTION
The reservoir may be hot so be careful not to burn
yourself.
NOTICE
Avoid overfilling, or the power steering could bedamaged.
When adding the power steering fluid, avoid spillingit. The generator under the power steering reservoircould be damaged if fluid is spilled on it.
CHECKING TIRE INFLATION PRESSURE
SV61010a
The recommended cold tire inflation pressure, tire
size and the combined weight of occupants and
cargo (vehicle capacity weight) are described on the
tire and loading information label.

You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget the
spare. The inflation pressure for the spare tire should be
adjusted according to the conditions in the table on page
344, 346 or 347.
The following instructions for checking tire inflation
pressure should be observed:
 The inflation 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.
 Always use a tire pressure gauge. The appearance
of the tire can be misleading. Besides, tire inflation
pressures that are even just a few pounds off can
degrade ride and handling.
 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.
CAUTION
The inflation pressure for the compact spare tire
must be 420 kPa (4.3 kgf/cm2, 4.2 bar, 60 psi).
Inspection and adjustment procedure
SV63010

1Tire valve
2Tire 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.
5. After completing the tire inflation pressure
measurement and adjustment, apply soapy water to the
valve and check for leakage.

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.
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
load 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 the Certification
Label and sidewall of the tire, see pages 316 and 354.

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 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
CAUTION
Do not modify the suspension/chassis with lift kits,
spacers, springs, etc. It can cause dangerous handling
characteristics, resulting in loss of control.
