*Change automatic transmission fluid only as necessary.
Generally, it is necessary to change automatic transmission
fluid only if your vehicle is driven under one of the Special
Operating Conditions listed in your “Owner’s Manual
Supplement/Scheduled Maintenance”. When changing the
automatic transmission fluid, use only “Toyota Genuine ATF
Type T−IV” (ATF JWS3309 or NWS6500) to aid in assuring
optimum transaxle performance.NOTICE
Using automatic transmission fluid other than “Toyota
Genuine ATF Type TIV” may cause deterioration in
shift quality, locking up of your transmission
accompanied by vibration, and ultimately damage the
automatic transmission of your vehicle.
Please contact your Lexus dealer for further details.

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 − 80C or 140F − 175F). You may also check the level
when the fluid is cold (about room temperature, 10 C − 30C
or 50F − 85F) 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.
