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

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

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.

excessive wear; check brake rotors for
runout. Check brake calipers for fluid
leakage. Some models are equipped

Replace at specified intervals. More
frequent replacement may be required
when driving in dusty conditions,
heavy traffic areas, urban areas, desert
areas or dirt roads. Refer to your
Owner’s Manual for service details.
Differential Oil
Inspect each differential component for
signs of leakage. If you discover any
leakage, have it repaired immediately
by a qualified technician. Refer to your
Owner’s Manual for fluid specifications.
Drive Belt
Inspect for cracks, excessive wear
and oiliness. Check the belt tension
and adjust if necessary. Replace the
belt if it is damaged.
Driver’s Floor Mat
•
Only use the driver’s floor mat
de signed specifically for the model
and model year of your vehicle,
such as Lexus Genuine floor mats.
• Always properly secure the
driver’s floor mat using the
retaining hooks.
• Never install another floor mat
on top of the existing driver’s
floor mat.
• Never install the driver’s floor
mat upside down.
Engine Air Filter
Check for excessive dirt, damage
and oiliness. Replace if necessary.
Engine Coolant
When inspecting, visually check
the engine coolant level on the
see-through reservoir. Add coolant
as necessary. When replacing,
drain the cooling system and refill
with coolant. Always use Genuine
Toyota Super Long-Life Coolant
or similar high-quality non-silicate,
non-amine, non-nitrate, non-borate
ethylene-glycol coolant with long-life
hybrid organic acid technology
(i.e., a combination of low phosphates
and organic acids). Check that the
radiator is not blocked with leaves,
dirt or insects and clean if necessary.
Also check the hose connection for
cor rosion and condition of installation.
A qualified technician should perform

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.
