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 fluid
The transmission 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.
Inspect the transmission/front
differential assembly case for signs
of leakage. (The front electric motor/
generators do not require periodic
maintenance.) Any service that
requires inspecting or replacing
transmission/front differential fluid
should be performed by a qualified
technician following procedures in
Lexus service and repair publications.
Please refer to the important safety
precautions found on the inside front
cover of this booklet.
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.
