CHECKING POWER STEERING
FLUID
Check the fluid level through the reservoir. 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 hot O.K.
If hot add
If cold O.K.
If cold 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 the level is at
the low side of the appropriate range, add automatic transmission
fluid DFXRON
®-II 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 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 lever 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.)
