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
432 for additional information.
Engine coolant level
Make sure the coolant level is between the ºFULLº and
ºLOWº lines on the see±through reservoir when the
engine is cold. See page 383 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 415 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 391
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 378 for
additional information.
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 393 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 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.

To check the fluid level, simply look at the
see±through
reservoir. The level should be between
the ºMAXº and ºMINº lines on the tank.
It is normal for the brake fluid level to go down slightly as
the brake pads wear. So be sure to keep the reservoir
filled.
If the reservoir needs frequent refilling, it may indicate a
serious mechanical problem.
If the level is low, add FMVSS No.116 DOT 3 or SAE
J1703 brake fluid to the brake reservoir.
Remove and replace the reservoir cover by hand. Add
brake fluid up to the ºMAXº line.
Use only newly opened brake fluid. Once opened, brake
fluid absorbs moisture from the air, and excess moisture
can cause a dangerous loss of braking efficiency.
CAUTION
Take care when filling the reservoir because brake fluid
can harm your hands or eyes and damage painted
surfaces. If fluid gets in your hands or eyes, flush them
with clean water.
