EXPLANATION OF MAINTENANCE ITEMS
MAINTENANCE
Scheduled Maintenance Log
The following descriptions are provided
to give you a better understanding of
the maintenance services that should
be performed on your vehicle. The
scheduled maintenance log indicates
at which time/mileage intervals each
service should be performed. Please
note that many maintenance services
should be performed only by a
qualified technician.
Axle Shaft Boots
Check the axle shaft boots and
clamps for cracks, deterioration
and damage. Replace any damaged
parts and, if necessary, repack
the grease. A qualified technician
should perform these operations.
Ball Joints and Dust Covers
Check the suspension and steering
linkage ball joints for looseness
and damage. Check all dust covers
for deterioration and damage. A
qualified technician should perform
these inspections.
Body Inspection
Visually check for corrosion, scratches
and other damage. Check outer
body panels, inner panels of the
hood and doors, and underneath the
vehicle. Apply touch-up paint to any
chips and scratches or have them
repaired by a qualified technician.
Brake Fluid
Replace using fluid type specified in
your Owner’s Manual. A qualified tech-
nician should perform this operation.
Brake Lines and Hoses
Visually inspect for proper installation.
Check for chafing, cracks, deterioration
and signs of leakage. Replace any
deteriorated or damaged parts.
A qualified technician should perform
these operations.
Brake Pads, Calipers and Rotors
Check brake pads and rotors for
excessive wear; check brake rotors for
runout. Check brake calipers for fluid
leakage. Some models are equipped
with directional rotors. When servicing
these rotors, reinstall at same location.
A qualified technician should perform
these operations.
For further information on
maintenance services that you
can perform yourself, see the
maintenance sections of your
Owner’s Manual.

EXPLANATION OF MAINTENANCE ITEMS
MAINTENANCE
Scheduled Maintenance Log
Spark Plugs
Replace at specified interval. Install
new plugs of the same type as origi-
nally equipped. A qualified technician
should perform this operation.
Steering Linkage and Boots
With the vehicle stopped, check for
excessive freeplay in the steering wheel.
Inspect the linkage for bending and
damage and the dust boots for deterio-
ration, cracks and damage. Replace any
damaged parts. A qualified technician
should perform these operations.
Timing Chain
The timing chain requires no
periodic inspection.
Tire Rotation
See your Owner’s Manual for tire
rotation requirements. Check tire
pressure and check tires for damage
and uneven wear. If the vehicle is
equipped with a spare tire, check the
condition and pressure of the spare.
Tire-Pressure Warning Sensors
A tire-pressure sensor is mounted on
each full-size wheel. These sensors
do not require periodic maintenance.
When a sensor’s long-life lithium battery
becomes discharged, the battery should
be replaced by a qualified technician
following procedures in Lexus service
and repair publications.
Transmission/Transfer Case
Inspect transmission/transfer case for
signs of leakage. If you discover any
leakage, have it repaired immediately
by a qualified technician.
Note: The trans mission/transfer case
and transmission fluid are a completely
sealed unit. Therefore, periodic checks
and replacement of the transmission
fluid are not required, and there is no
dipstick on the transmission. Any repairs
that require adding or replacing fluid
should be performed by a qualified
technician following procedures in
Lexus service and repair publications.
Wiper Blades
The wiper blades should not show
any signs of cracking, splitting, wear,
contamination or deformation. The
wiper blades should clear the wind-
shield without streaking or skipping.
