CHECKING POWER STEERINGFLUID
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 80 C or 140 F 175F). You may also check the level
when the fluid is cold (about room temperature, 10 C 30 C
or 50 F 85 F) if the engine has not been run for about five
hours.
 1 If cold O.K. 2If cold add 3If 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 “COLD” range. Similarly,
if it is hot, the fluid level should be in the “HOT” range. If th\
e
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.

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 air
pressure for the spare tire should be adjusted according to the
conditions in the table on page 312. 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 ride and handling.
 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.
