automatic transmission fluid lexus LS400 1998 Audio System / LEXUS 1998 LS400 OWNER'S MANUAL (OM50498U)

MAINTENANCE
216Parking brake
Check that the pedal has the proper travel and that, on a safe incline,
your vehicle is held securely with only the parking brake applied.
Automatic transmission ”Park” mechanism
On a safe incline, check that your vehicle is held securely with the
selector lever in ”P” 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 261 for
additional information.
Engine coolant level
Make sure the coolant level is between the Upper and Lower lines
on the seethrough reservoir when the engine is cold. See page 233
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 253
for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 239 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 230 for additional
information.
Power steering fluid level
Check the level on the dipstick. The level should be in the ”HOT”
or ”COLD” range depending on the fluid temperature. See page 240
for additional information.
Exhaust system
Look for cracks, holes and loose supports. If you notice any change
in the sound of the exhaust or smell exhaust fumes, have the cause
located and corrected immediately. (See engine exhaust cautions in
Section 31.)

INTRODUCTION
222Remember 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, or the
transmission could be damaged.
Be careful not to scratch the glass surface with the wiper
frame.

CHECKING POWER STEERING
FLUID
63L0021
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 (60C
8 0C 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.

If hot O.K. 3
Add fluid
1. Clean all dirt off the reservoir.
2. Remove the filler cap by turning it counterclockwise and wipe the
dipstick clean.
3. Reinstall the filler cap.
4. Remove the filler cap again and look at the fluid level. If the fluid
is cold, the level should be in the ”COLD” range on the dipstick.
Similarly, if it is hot, the fluid level should be in the ”HOT” 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 filler cap, visually check the steering box case,
vane pump and hose connections for leaks or damage.
