2082. With the brake fully depressed, start the engine: the pedal
should move down a little when the engine starts.
3. Depress the brake, stop the engine, and hold the pedal in
for about 30 seconds: the pedal should neither sink nor rise.
4. Restart the engine, run it for about a minute and turn it off.
Then firmly depress the brake several times: the pedal travel
should decrease with each application.
CHECKING POWER STEERING
FLUID
Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRON®-II.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 − 175
F). 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.
If cold O.K.
If cold add
If hot O.K.
If hot add
a. Clean all dirt off the reservoir.
b. Remove the filler cap by turning it counterclockwise and
wipe the dipstick clean.
c. Reinstall the filler cap.
d. Remove the filler cap again and look at the fluid level. If the
fluid is cold, the level should be in the “COLD” range on the
dipstick. Similarly, if it is hot, the fluid level should be in the
“HOT” range. If the level is at the low side of either range, add
automatic transmission fluid DEXRON
®-II to bring the level
within the range.
e. After replacing the filler cap, visually check the steering box
case, vane pump and hose connections for leaks or damage.

209 CAUTION:
The reservoir may be hot so be careful not to burn
yourself.
NOTICE:
Avoid overfilling, or the power steering could be
damaged.
When adding the power steering fluid, avoid spilling
it. The generator under the power steering reservoir
could be damaged if fluid is spilled on it.
CHECKING STEERING WHEEL
FREEPLAY
30 mm (1.2 in.)
Max.
With the vehicle stopped and the front wheels pointed
straight ahead, rock the steering wheel gently back and
forth. If the freeplay is more than specified, have it
inspected by your Lexus dealer.
Use only a very light finger pressure to rock the wheel slowly.
CHECKING AUTOMATIC
TRANSMISSION FLUID
1. Check the fluid level only when the transmission is at
normal operating temperature. With the vehicle level, first
set the parking brake and then start the engine. While the
engine is idling, depress the brake pedal and shift the
selector level into each position from “P” to “L” and return
to “P”.
If the vehicle has been driven over 16 km or 10 miles (24 km
or 15 miles in frigid temperatures) and the fluid temperature is
70
C − 80
C (160
F − 175
F), the transmission is at normal
operating temperature.
You may check the level when the transmission is cold. If the
vehicle has not been driven for over five hours and the fluid is
about room temperature 20
C − 30
C (70
F − 85
F), the
transmission is cold.
However, checking a cold transmission is to be used for your
reference only and the transmission must be checked again for
correct level at normal operating temperature.
If the vehicle has just been driven for a long time at high speed,
in city traffic in hot weather, or the vehicle has been pulling a
trailer, an accurate fluid level cannot be obtained. Check the
level after the fluid has cooled down (about 30 minutes).
