MAINTENANCE
291
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.
Automatic transmission ºParkº mechanism
On a safe incline, check that your vehicle is held securely with
the selector lever in ºPº position and all brakes released.
Engine compartment
Items listed below should be checked from time to time,
e.g. each time when refueling.
Washer fluid
Make
sure there is sufficient fluid in the tank. See page 344 for
additional information.
Engine coolant level
Make sure the coolant level is between the Upper and Lower
lines on the see±through reservoir when the engine is cold.
See page 313 for additional information.
Battery
Your Lexus has a maintenance free battery. You do not have
to add distilled water. For longer life of the battery, however,
see page 338 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 321 for
additional information. Engine oil level
Check the level on the dipstick with the engine turned off and
the vehicle parked on a level spot. See page 310 for additional
information.
Power steering fluid level
Check the level on the dipstick. The level should be in the
ºHOTº or ºCOLDº range depending on the fluid temperature.
See page 322 for additional information.
Exhaust system
If you notice any change in the sound of the exhaust or smell
exhaust fumes, have the cause located and corrected
immediately. (See ªEngine exhaust cautionsº on page 221 in
Section 3±1.)

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 backfiringcould cause a fire in the engine compartment.

Do not overfill automatic transmission fluid, or thetransmission could be damaged.

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

CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:

Follow jacking instructions.

Do not put any part of your body under the vehicle
supported by a jack. Personal injury may occur.

Do not start or run the engine while your vehicle is
supported by the jack.

Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in ºPº
(automatic) or reverse (manual). Block the wheel
diagonally opposite to the one being changed if
necessary.

Make sure to set the jack properly in the jack point.
Raising the vehicle with jack improperly positioned
will damage the vehicle or may allow the vehicle to fall
off the jack and cause personal injury.

Never get under the vehicle when the vehicle is
supported by the jack alone; use vehicle support
stands.

Do not raise the vehicle with someone in the vehicle.

When raising the vehicle, do not put an object on or
under the jack.

*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 ºOwner's Manual
Supplement/Scheduled Maintenanceº. When changing the
automatic transmission fluid, use only Toyota Genuine ATF
Type T±IV ( ATF JWS3309 or NWS6500) to aid in assuring
optimum transmission performance.NOTICE
Using automatic transmission fluid other than Toyota Genuine ATF T ype T±IV may cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ultimately damage the automatictransmission of your vehicle.

CHECKING POWER STEERINGFLUID
SV63002
Check the fluid level on the dipstick. 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.

1If cold O.K. 2If hot O.K. 3Add fluid
1. Clean all dirt off the reservoir.
2. Remove the reservoir cap by turning it counterclockwise
and wipe the dipstick clean.
3. Reinstall the reservoir cap.
4. Remove the reservoir cap again and look at the fluid level.
If the fluid is cold, the level should be in the ºCOLDº range on
the dipstick. Similarly, if it is hot, the fluid level should be in the
ºHOTº range. If the level is at the low side of either range, add
automatic transmission fluid DEXRON
II or III to bring the
level within the range.
5. After replacing the reservoir cap, visually check the
steering box case, vane pump and hose connections for leaks
or damage.
