EXPLANATION OF MAINTENANCE ITEMS
Spark Plugs
Replace at specified interval. Install
new plugs of the same type as originally
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 deterioration, 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.
Variable Gear Ratio Steering
Assembly (if equipped)
Inspect the variable gear ratio steering
assembly for damage and loose
electrical connections. Tighten loose
connections and if you discover any
damage, have it repaired immediately
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 windshield without streaking
or skipping.
