Lexus ES300 1998 Owner's Manuals (in English)

MAINTENANCE183
Accelerator pedal
Check the pedal for smooth operation and uneven pedal effort or catching.
Brake pedal
Check the pedal for smooth operation and the proper clearance and freeplay.
Check the brake booster function.
Brakes
At a safe place, check that the brakes do not pull to one side when appl\
ied.
Parking 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 ºParkº mechanism
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 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 227 for additional
information.
Engine coolant level
Make sure the coolant level is between the ºFULLº and ºLOWº line\
s on the
see±through reservoir when the engine is cold. See page 201 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 219 for additional
information.
Brake fluid level
Make sure the brake fluid level is correct. See page 205 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 198 for additional information.

MAINTENANCE
184
Power steering fluid level
Check the level through the reservoir. The level should be in the ºHOTº or
ºCOLDº range depending on the fluid temperature. See page 206 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 3±1.)
DOES YOUR VEHICLE NEED
REPAIRING?
Be on the alert for changes in performance and sounds, and visual tip±o\
ffs that
indicate service is needed. Some important clues are:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A fluid leak under the vehicle (However, water dripping from the air
conditioning after use is normal.)

Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)

Flat±looking tires, excessive tire squeal when cornering, uneven tire wear

Vehicle pulls to one side when driving straight on a level road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches floors, vehicle pulls to one side when braking

Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to your Lexus dealer a\
s soon
as possible. It probably needs adjustment or repair.
CAUTION
Do not continue driving with the vehicle unchecked. It could
result in serious vehicle damage and possibly personal injury.

DO±IT±YOURSELF SERVICEPRECAUTIONS
If you perform maintenance yourself, be sure to follow the correct
procedure given in this Section.
You should be aware that improper or incomplete servicing may result in
operating problems.
Performing do±it±yourself maintenance during the warranty period may
affect your warranty coverage. Read the separate Lexus Warranty statement
for details and suggestions.
This Section gives instructions only for those items that are relatively eas\
y for
an owner to perform. As explained in Section 5, there are still a number \
of
items that must be performed by a qualified technician with special tools.
For information on tools and parts for do±it±yourself maintenance, se\
e ºParts
and toolsº.
Utmost care should be taken when working on your vehicle to prevent
accidental injury. Here are a few precautions that you should be especially
careful to observe:
CAUTION

When the engine is running, keep hands, clothing, and tools
away from the moving fan and engine drive belt.
(Removing rings, watches, and ties is advisable.)

Right after driving, the engine compartment ± the engine,
radiator, exhaust manifold and power steering fluid
reservoir, etc. ± will be hot. So be car eful not to touch them.
Oil and other fluids may also be hot.

Do not smoke, cause sparks or allow open flames near fuel
or the battery. Their fumes are flammable.

Be extremely cautious when working on the battery. It
contains poisonous and corrosive sulfuric acid.

Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or other
solid supports.

Use eye protection whenever you work on or under your
vehicle where you may be exposed to flying or falling
material, fluid spray, etc.

INTRODUCTION189
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, or the transmission could
be damaged.

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