* 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 BRAKE FLUID
To check the fluid level, simply look at the seethrough
reservoir. The level should be between the “MAX” and
“MIN” lines on the tank.
It is normal for the brake fluid level to go down slightly as the
brake pads wear. So be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it may indicate a serious
mechanical problem.
If the level is low, add FMVSS No.116 DOT 3 or SAE J1703
brake fluid to the brake reservoir.
Remove and replace the reservoir cap by hand. Add brake
fluid up to the “MAX” line.
Use only newly opened brake fluid. Once opened, brake fluid
absorbs moisture from the air, and excess moisture can cause
a dangerous loss of braking efficiency.
CAUTION
Take care when filling the reservoir because brake fluid
can harm your hands or eyes. If fluid gets on your hands
or in your eyes, flush the affected area with clean water
immediately. If you still feel uncomfortable with your
hands or eyes, go to the doctor.
NOTICE
If you spill some of the fluid, be sure to wipe it off to
prevent it from damaging the parts or paintwork.

CHECKING POWER STEERINGFLUID
The power steering fluid reservoir is located under the
engine compartment cover. Before checking the power
steering fluid, remove the cover. (For details, see
“Removing the e ngine compartment cover” on page 540.)
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 —
30 C or 50F — 85F) if the engine has not been run for about
five hours.
1If cold O.K.2If cold add3If 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 INFLATIONPRESSURE

CHASSIS
571
The recommended cold tire inflation pressures,
tire sizes and the combined weight of occupants
and cargo (vehicle capacity weight) are described
on pages 566 and 616. They are also described
on the tire and loading information label as
shown.
You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget
the spare!
The following instructions for checking tire
inflation 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 inflation pressure reading.
 Always use a tire pressure gauge. The
appearance of a tire can be misleading. Besides,
tire inflation pressures that are even just a few
pounds off can degrade handling and ride.
 Do not bleed or reduce tire inflation pressure
after driving. It is normal for the tire inflation
pressure to be higher after driving. 
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be located
so that the vehicle is balanced.
Inspection and adjustment procedure
1Tire valve
2Tire pressure gauge
1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire
valve.
3. Read the pressure using the graduations of the
gauge.
