Lexus will not deny a warranty claim
solely because you do not have
records to show that you maintained
your vehicle. However, any failure or
noncompliance caused by lack of
maintenance is not covered by this
warranty.
When maintenance and repairs are
paid for by you, these services may
be performed by you or by any auto-
motive service provider you choose.
Lexus will not deny a warranty claim
solely because you used a service
provider other than a Lexus dealer-
ship for maintenance and repairs.

EXPLANATION OF MAINTENANCE ITEMS
MAINTENANCE
Scheduled Maintenance Log69
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 quali-
fied technician should perform these
operations.
Timing Belt (SC)
Replace every 90,000 miles or
108 months. A qualified technician
should perform this operation.
Timing Chain (ES, GS, IS, LS)
The ES, GS, IS and LS are equipped
with a timing chain that requires no
periodic inspection.
Tire Rotation
Tires should be rotated according
to the instructions in your Owner’s
Manual . When rotating tires, check
pressure and check for damage and
uneven wear. If the spare is not rotat-
ed, 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 bat-
tery becomes discharged, the battery
should be replaced by a qualified
technician following procedures in
Lexus service and repair publications.
Transfer Case/Transmission
Inspect each transfer case/transmis-
sion component for signs of leakage.
If you discover any leakage, have it
repaired immediately by a qualified
technician.
Note:
The transfer case/transmission
and transmission fluid are a complete-
ly sealed unit. Therefore, periodic
checks and replacement of the trans-
mission fluid are not required, and
there is no dipstick on the transmis-
sion. Any repairs that require adding
or replacing fluid should be per-
formed by a qualified technician fol-
lowing procedures in Lexus service
and repair publications.
