Timing Chain; Tire Rotation; Wiper Blades - Lexus RX 450h Warranty And Services Manual

EXPLANATION OF MAINTENANCE ITEMS
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.
72 Scheduled Maintenance Log
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.
