(i) Automatic Transmission Fluid Temperature
Warning Light
This light warns that the automatic transmission fluid
temperature is too high.If this light comes on while you are driving, slow down and pull
off the road. Stop the vehicle at a safe place and put the
selector lever in Pº and leave the engine idling until the light
goes off. If the light goes off, you can start the vehicle again.

MAINTENANCE
491 Brakes
At a safe place, check that the brakes do not pull to one side
when applied.
Parking brake
Check that the lever has the proper travel and that, on a safe
incline, your vehicle is held securely with only the parking brake
applied.

Check the lock release button of the selector lever for proper
and smooth operation. On a safe incline, check that your
vehicle is held securely with the selector lever in Pº position
and all brakes released.
Vehicle exterior
Items listed below should be performed from time to time,
unless otherwise specified.
Fluid leaks
Check underneath for leaking fuel, oil, water or other fluid after
the vehicle has been parked for a while. If you smell fuel fumes
or notice any leak, have the cause found and corrected
immediately.
Doors and engine hood
Check that all side doors and back door, operate smoothly and
all latches lock securely. Make sure the engine hood
secondary latch secures the hood when the primary latch is
released.
Tire inflation pressure
Check the pressure with a gauge every two weeks,
or at least once a month and adjust as shown on the
tire pressure label. See page 532 for additional
information.
Tire surface
Check the tires carefully for cuts, damage or
excessive wear. See page 545 for additional
information.
Wheel nuts
When checking the tires, make sure to check the nuts
for looseness. Tighten them if necessary.
Tire rotation

NOTICE

Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally
causing a short circuit.

Before closing the engine hood, check to see that you
have not forgotten any tools, rags, etc.

Do not drive with the air cleaner removed, or
excessive engine wear could result. Also backfiring
could cause a fire in the engine compartment.

Do not overfill automatic transmission fluid and
power steering fluid, or the transmission and power
steering could be damaged.

Be careful not to scratch the glass surface with the
wiper frame.

*: 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 Maintenanceº. When changing the
automatic transmission fluid, use only Toyota Genuine ATF
WSº (ATF JWS3324 or NWS9638) to aid in assuring optimum
transmission performance.

Genuine ATF WSº 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 STEERING
FLUID
The power steering fluid reservoir is located under the
right side engine compartment cover. Before checking
the power steering fluid, remove the cover. (For details,
see Removing the engine compart coversº on page 500.)
Check the fluid level, simply look at the see-through
reservoir. If necessary, add automatic transmission fluid
DEXRON
II 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
(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.

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 COLDº range. Similarly,
if it is hot, the fluid level should be in the HOTº range. If the
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.
