Engine coolant level
Make sure the coolant level is between the ªFULLº and

engine is cold. See page 407 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 443 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 416
for additional information.

Check the level on the dipstick with the engine turned off
and the vehicle parked on a level spot. See page 402 for
additional information.
Power steering fluid level
Check the level through the reservoir. The level should
be in the ªHOTº or ªCOLDº range depending on the fluid temperature. See page 418 for additional information.
Exhaust system

smell exhaust fumes, have the cause located and
corrected immediately.
(See engine exhaust cautions in
Section 3±1.)

MAINTENANCE

DOES YOUR VEHICLE NEEDREPAIRING?
Be on the alert for changes in performance and sounds,
and visual tip±offs 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 as soon as possible. It probably needs
adjustment or repair.
