CHECKING POWER STEERING FLUID
63E002±1
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 (60 C ± 80C or 140F ± 175F).
You may also check the level when the fluid is cold (about room temperatur\
e,
10 C ± 30C or 50F ± 85F) if the engine has not been run for about five
hours.

Clean all dirt off the reservoir and look at the fluid level. If the fluid is cold,
the level should be in the ºCOLDº range. Similarly, if it is hot, the fluid level
should be in the ºHOTº range. If the level is at the low side of the appropria\
te
range, add automatic transmission fluid DEXRON
II or III to bring the level
within the range.
To remove the filler cap, turn it counterclockwise and lift up. To reinstall it,
turn it clockwise. After replacing the filler 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.

NOTICE
Avoid overfilling, or the power steering could be damaged.
CHECKING TIRE PRESSURE
63E004±1
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 mon\
th.
And don't forget the spare! The air pressure for the spare tire should be 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 ca\
ps
have been lost, have new ones put on as soon as possible.
