MAINTENANCE
147 Your copy of the repair order is proof that all required
maintenance has been performed for warranty coverage. And
if any problems should arise with your vehicle while under
warranty, your Lexus dealer will promptly take care of it. Again,
be sure to keep a copy of the repair order for any service
performed on your Lexus.
What about do−it−yourself maintenance?
Many of the maintenance items are easy to do yourself, if you
have a little mechanical ability and a few basic automotive
tools. Simple instructions for how to perform them are
presented in Section 6.
If you are a skilled do−it−yourself mechanic, the Lexus service
manuals are recommended. Please be aware that
do−it−yourself maintenance can affect your warranty
coverage. See your Owner’s Guide or Warranty Booklet for the
details.
GENERAL MAINTENANCE
Listed below are the general maintenance items that should be
performed at the intervals specified. It is recommended that
any problem you notice be brought to the attention of your
Lexus dealer or qualified service shop for their advice.
CAUTION:
Make these checks only where adequate ventilation can
be obtained if you run the engine.
Vehicle exterior
Items listed below should be performed from time to time,
unless otherwise specified.
Tire pressure
Check the pressure with a gauge every two weeks, or at least
once a month and adjust as shown on the tire pressure label.
See page 182 for additional information.
Tire surface
Check the tires carefully for cuts, damage or excessive wear.
See page 183 for additional information.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary.
Tire rotation
Rotate the tires every 12000 km (7500 miles). See page 183
for additional information.

MAINTENANCE
148Fluid leaks
Check underneath for leaking fuel, oil, water or other fluid after
the vehicle has been parked for a while. If you smell fuel fumes
or notice any leak, have the cause found and corrected
immediately.
Doors and engine hood
Check that all doors, including trunk lid, operate smoothly and
all latches lock securely. Make sure the engine hood
secondary latch secures the hood when the primary latch is
released.
Vehicle interior
Items listed below should be checked regularly, e.g. while
performing periodic services, cleaning the vehicle, etc.
Lights
Make sure the headlight, stop lights, tail lights, turn signal
lights, and other lights are working. Check headlight aim.
Service reminder indicators and warning buzzers
Check that all service reminder indicators and warning
buzzers function properly.
Steering wheel
Check that it has the specified freeplay. Be alert for changes
in steering condition, such as hard steering, excessive
freeplay or strange noise.
Seats
Check that all front seat controls such as seat adjusters,
seatback recliner, etc. operate smoothly and that all latches
lock securely in any position. Check that the head restraints
move up and down smoothly and that the locks hold securely
in any latched position.
Seat belts
Check that the seat belt system such as buckles, retractors
and anchors operate properly and smoothly. Make sure the
belt webbing is not cut, frayed, worn or damaged.

MAINTENANCE
149 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 applied.
Parking brake
Check that the lever 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
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 “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 199 for
additional information.
Engine coolant level
Make sure the coolant level is between the “FULL” and “LOW”
lines on the see−through reservoir. See page 175 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 194 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 180 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 173 for additional
information.

MAINTENANCE
150Power steering fluid level
Check the level through the reservoir. The level should be in
the “HOT” or “COLD” range depending on the fluid
temperature. See page 181 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
