CHECKING THE BRAKE
BOOSTER
Sit in the driver’s seat and follow the instructions given
below. If your brakes do not operate as described, have
them checked at your Lexus dealer.
1. With the engine stopped, depress the brake pedal several
times: the travel distance should not change.
2. 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 sink slightly when the
engine stops. Afterward, 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
Power steering
fluid reservoir
Check the fluid level through the reservoir. If necessary,
add DEXRON®-II automatic transmission fluid.
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 − 80C or 140F − 175F). You may also check the level
when the fluid is cold (about room temperature, 10C − 30C
or 50F − 85F) if the engine has not been run for about five
hours.

If hot O.K.
If hot add
If cold O.K.
If cold add
Clean all dirt from outside of the reservoir tank 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 the level is at the low side of the appropriate range,
add DEXRON
®-II automatic transmission fluid 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 tank may be hot so be careful not to burn
yourself.
NOTICE:
Avoid overfilling, or the power steering could be
damaged.
