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.

Brake linings and drums
Check for scoring, burning, leaking fluid, broken parts, and
excessive wear. A qualified technician should perform this
operation.
Brake pads and discs
Check the pads for excessive wear and discs for runout and
wear, and leaking fluid. A qualified technician should perform
