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

CHECKING POWER STEERING
FLUID
Check the fluid level through the reservoir. If necessary,
add automatic transmission fluid DEXRONII or III.
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 Ð 80C or 140F Ð 175F). You may also check the
level when the fluid is cold (about room temperature, 10C Ð
30C or 50F Ð 85F) if the engine has not been run for about
five hours.

1If cold O.K.2If cold add3If hot O.K.
4If hot add
Clean all dirt off the reservoir and look at the fluid level. If the
fluid is cold, the level should be in the COLDº range. Similarly,
if it is hot, the fluid level should be in the HOTº range. If the
level is at the low side of the appropriate range, add automatic
transmission fluid DEXRON
II or III to bring the level within
the range.
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.
CAUTION
The reservoir may be hot so be careful not to burn
yourself.

Avoid overfilling, or the power steering could be
damaged.

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 384 and 441. 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.
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. The
passengers and luggage weight should be located
so that the vehicle is balanced.

Inspection and adjustment procedure

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 a graduation of the gauge.
4. In case that 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 soap water to
the valve and check the leakage.
6. Install the tire valve cap.If the gauge and the 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.

CHASSIS

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) Ð
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts from overheated tire
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road
hazards
High tire pressure (overinflation) Ð
Poor handling
Excessive wear
Uneven wear
A greater possibility of tire damage from road
hazards

1Summer tire or all season tire: An all season
tire has M+Sº on the sidewall. The tire not
marked with M+Sº is a summer tire. For details,
see Types of tiresº on page 400.
2Tire size: For details, see Tire sizeº on page
394.
3DOT and Tire Identification Number (TIN): For
details, see DOT and Tire Identification Number
(TIN)º on page 394.
4Uniform tire quality grading: For details, see
Uniform tire quality gradingº that follows.
5Location of the tread wear indicators: For
details, see Checking and replacing tiresº on
page 402.
6Tire ply composition and materials: Plies mean
a layer of rubber-coated parallel cords. Cords
mean the strands forming the plies in the tire.
7Radial tires or bias-ply tires: A radial tire has
RADIALº on the sidewall. The tire not marked
with RADIALº is a bias-ply tire.
8TUBELESSº or TUBE TYPEº: A tubeless tire
does not have a tube inside the tire. A tube type
tire has a tube inside the tire and the tube
maintains the air pressure.
9Load limit at maximum cold tire inflation
pressure: For details, see Checking and
replacing tiresº on page 402.
10Maximum cold tire inflation pressure: This
means the pressure to which a tire may be
inflated. For details about recommended cold tire
inflation pressure, see Specificationsº on page
384.
