Your Lexus vehicle has been designed to have fewer
maintenance requirements with longer service intervals to
save both your time and money. However, each regular
maintenance as well as day−to−day care is more important
than ever before to ensure smooth, trouble−free, safe, and
economical driving.
It is the owner’s responsibility to make sure the specified
maintenance, including general maintenance services, is
performed. Note that both the new vehicle and emission
control system warranties specify that proper maintenance
and care must be performed. See the “Owner’s Guide”,
“Owner’s Manual Supplement” or “Warranty Booklet” for
complete warranty information.
General maintenance
General maintenance items are those day−to−day care
practices that are important to your vehicle for proper
operation. It is the owner’s responsibility to ensure that the
general maintenance items are performed regularly.
These checks or inspections can be done either by yourself or
your Lexus dealer.
Scheduled maintenance
The scheduled maintenance items listed in the “Owner’s
Manual Supplement/Scheduled Maintenance” are those
required to be serviced at regular intervals.
For details of your maintenance schedule, read the “Owner’s
Manual Supplement/Scheduled Maintenance”.
It is recommended that any replacement parts used for
maintenance or for the repair of the emission control
system be Lexus supplied.
The owner may elect to use non−Lexus supplied parts for
replacement purposes without invalidating the emission
control system warranty. However, use of replacement
parts which are not of equivalent quality may impair the
effectiveness of the emission control systems.
You may also elect to have maintenance, replacement, or
repair of the emission control devices and system
performed by any automotive repair establishment or
individual without invalidating this warranty. See
“Owner’s Guide”, “Owner’s Manual Supplement” or
“Warranty Booklet” for complete warranty information.
Where to go for service?
Lexus technicians are well−trained specialists and are kept up
to date with the latest service information through technical
bulletins, service tips, and in−dealership training programs.
They are well informed about the operation of all the systems
on your vehicle.
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.
You can be confident that your Lexus dealer’s service
department performs the best job to meet the maintenance
requirements of your vehicle.
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”, “Owner’s Manual
Supplement” or “Warranty Booklet” for the details.
Make these checks only where adequate ventilation can
be obtained if you run the engine.

Fluid leaks
Make sure the headlight, stop lights, tail lights, turn signal
lights, and other lights are working. Check headlight aim.
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
Service reminder indicators and warning buzzers
Check that all service reminder indicators and warning
buzzers function properly.
Doors and engine hood
Steering wheel
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
Check that it has the specified freeplay. Be alert for changes
in steering condition, such as hard steering, excessive
freeplay or strange noise.
Check that all front seat controls such as seat adjusters,
seatback recliner, etc. operate smoothly. 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.
Accelerator pedal
Engine compartment
Check the pedal for smooth operation and uneven pedal effort
or catching.
Items listed below should be checked from time to time,
e.g. each time when refueling.
Brake pedal
Washer fluid
Check the pedal for smooth operation and the proper
clearance and freeplay. Check the brake booster function.
Make sure there is sufficient fluid in the tank. See page 348 for
additional information.
Engine coolant level
At a safe place, check that the brakes do not pull to one side
when applied.
Make sure the coolant level is between the “F” and “L” lines on
the see−through reservoir when the engine is cold. See page
315 for additional information.
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.
Radiator, condenser and hoses
Check that the front of the radiator and condenser are clean
and not blocked with leaves, dirt, or insects. See page 317 for
additional information.
Check the battery condition by the indicator color. See page
341 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 322 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 312 for additional
Power 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 323 for additional information.
Exhaust system
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 caution” on page 223.)
Be on the alert for changes in performance and sounds, and
visual tip−offs that indicate service is needed. Some important
clues are:
D Engine missing, stumbling, or pinging
D Appreciable loss of power
D Strange engine noises
D A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
D Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
D Flat−looking tires, excessive tire squeal when cornering,
uneven tire wear
D Vehicle pulls to one side when driving straight on a level
D Strange noises related to suspension movement
D Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
D 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
Some states have vehicle emission inspection programs
which include OBD (On−Board Diagnostics) checks.
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.
The OBD system monitors the operation of the emission
control system. When the OBD system determines that a
problem exists somewhere in the emission control system, the
malfunction indicator lamp comes on. In this case, your vehicle
may not pass the I/M test and need to be repaired. Contact
your Lexus dealer to service the vehicle.
Even if the malfunction indicator lamp does not come on, your
vehicle may not pass the I/M test as readiness codes have not
been set in the OBD system.
Readiness codes are automatically set during ordinary driving.
However, when the battery is disconnected or run down, the
codes are erased. Also, depending on your driving habits, the
codes may not be completely set.
Also, if the malfunction indicator lamp had come on recently
due to temporary malfunction such as a loose fuel tank cap,
your vehicle may not pass the I/M test.
The malfunction indicator lamp will go off after taking several
driving trips, but the error code in the OBD system will not be
cleared unless about 40 trips or more are taken.
If your vehicle does not pass the I/M test even the malfunction
indicator lamp does not come on, contact your Lexus dealer to
prepare the vehicle for re−testing.
