EXPLANATION OF MAINTENANCE ITEMS
MAINTENANCE
Scheduled Maintenance Log 71
Spark Plugs
Replace at specified interval. Install
new plugs of the same type as origi-
nally equipped. A qualified technician
should perform this operation. To
ensure optimum engine performance
on ES 350, replace only with Denso
FK20HR11 plugs or equivalent.
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 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 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.
