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.
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 ºOwner's Guideº, ºOwner's Manual
Supplementº or ºWarranty Bookletº 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 254 for additional information.
Tire surface
Check the tires carefully for cuts, damage or excessive wear.
See page 256 for additional information.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary.

MAINTENANCE
224Tire rotation
Rotate the tires according to the maintenance schedule. (For
scheduled maintenance information, please refer to the
ªOwner's Manual Supplementº or ªScheduled Maintenanceº.)
See page 255 for additional information.
Fluid leaks
Check under
neath 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 free play. Be alert for changes
in steering condition, such as hard steering, excessive free
play or strange noise.
Seats
Check that all front seat controls such as seat adjusters,
seatback recliner, etc. operate smoothly. Ch
eck 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
Check the pedal for smooth operation and uneven pedal ef fort
or catching.
Brake pedal
Check the pedal for smooth operation and the proper
clearance and free play. 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.

CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:

Follow jacking instructions.

Do not put any part of your body under the vehicle
supported by a jack. Personal injury may occur.

Do not start or run the engine while your vehicle is
supported by the jack.

Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in reverse.
Block the wheel diagonally opposite to the one being
changed if necessary.

Make sure to set the jack properly in the jack point.
Raising the vehicle with jack improperly positioned
will damage the vehicle or may allow the vehicle to fall
off the jack and cause personal injury.

Never get under the vehicle when the vehicle is
supported by the jack alone; use vehicle support
stands.

Do not raise the vehicle with someone in the vehicle.

When raising the vehicle, do not put an object on or
under the jack.

CAUTION
The reservoir may be hot so be careful not to burn
yourself.
NOTICE
Avoid overfilling, or the power steering could bedamaged.
When adding the power steering fluid, avoid spillingit. The generator under the power steering reservoircould be damaged if fluid is spilled on it.
CHECKING TIRE PRESSURE
SV61004
The recommended cold tire pressures, tire size and the
vehicle capacity weight are given on the label.
You should check the tire pressures every two weeks, or at
least once a month. And don't forget the spare! The pressure
for the spare tire should be the same with that for the standard
tire. (See page 250.) Incorrect tire pressure can reduce tire
life and make your vehicle less safe to drive.
Low tire pressure results in excessive wear, poor handling,
reduced fuel economy, and the possibility of blowouts from
overheated tires. Also, low tire pressure can cause poor
sealing of the tire bead. If the tire pressure is excessively low,
there is the possibility of wheel deformation and/or tire
separation. So keep your tire pressures at the proper level.
If a tire needs frequent refilling, have it checked by your Lexus
dealer.

CHASSIS
255
High tire pressure produces a harsh ride, handling problems,
excessive wear at the center of the tire tread, and a greater
possibility of tire damage from road hazards.
The following instructions for checking tire pressure should be
observed:

The pressure should be checked only when the tires are
cold. If your vehicle has been parked for at least 3 hours
and has not been driven for more than 1.5 km or 1 mile
since, you will get an accurate cold tire pressure reading.
 Always use a tire pressure gauge. The appearance of the
tire can be misleading. Besides, tire pressures that are
even just a few pounds off can degrade ride and handling.
 Do not bleed or reduce tire pressure after driving. It is
normal for the tire pressure to be higher after driving.
 Never exceed the vehicle capacity weight. The
passengers and luggage weight should be located so that
the vehicle is balanced.
 Be sure to reinstall the tire valve caps. Without the valve
caps, dirt or moisture could get into the valve core and
cause air leakage. If the caps have been lost, have new
ones put on as soon as possible.
ROTATING TIRES
SS63001
To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires according to the
maintenance schedule. (For scheduled maintenance
information, please refer to the ºOwner's Manual
Supplement/Scheduled Maintenanceº.) However, the
most appropriate timing for tire rotation may vary
according to your driving habits and road surface
conditions.
The wheel assemblies must be rotated as illustrated above.
Pattern A: For tire without turning direction indicators.
Pattern B: For tire with turning direction indicators.
When rotating tires, check for uneven wear and damage.
Abnormal wear is usually caused by incorrect tire pressure,
improper wheel alignment, out±of balance wheels, or severe
braking.
