181 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 “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 229 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 cool.
See page 205 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 224 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 210 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 203 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 211 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−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.
CAUTION
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.
SCHEDULED MAINTENANCE
Driving conditions under which you mainly operate your
vehicle determine which maintenance schedule you
follow.
In order to ensure smooth, trouble−free, safe and economical
driving, Lexus provides two maintenance schedules to be
selected according to your driving conditions: schedules A and
B. The instructions on which schedule to follow are given on
the next page.
The service interval for scheduled maintenance is
determined by the odometer reading or the time interval,
whichever comes first, shown in the schedule.
The maintenance service beyond the last period should
be performed at the same intervals.
The service interval of each item can be obtained from the
maintenance schedule.
