GENERAL MAINTENANCE AND REGULAR USE
MAINTENANCE
In addition to scheduled maintenance,
your Lexus requires ongoing general
maintenance such as fluid checks
and visual inspections. The recom-
mended guidelines for inspections
are listed below. Please refer to
the “Mainte nance” section of the
Owner’s Manual for a detailed
description of inspection procedures.
Every 30 Days
At least once every 30 days,
perform these inspections:
• Check engine oil level using
the dipstick
• Visually check engine
coolant level on the
see-through reservoir
• Visually check brake fluid level
on the see-through reservoir
• Visually check condition
of battery
• Check level of windshield
washer fluid
• Check tire pressure
• Check tires for damage
and wear
• Check installation of
driver’s floor mat
After a Car Wash
• Check installation of
driver’s floor mat
When Cleaning the Interior
• Remove dirt and dust with a
vacuum cleaner. Wipe dirty
surfaces with a soft cloth
dampened with warm water.
• When cleaning leather interior,
remove dirt and dust with a
vacuum cleaner. Using a
sponge, apply a small amount
of neutral wool detergent mixed
in water, rubbing in a circular
motion. Wipe off any excess
detergent and let leather dry
in an open-air location.
• When cleaning carpet, remove dirt
and dust with a vacuum cleaner.
Apply a foaming-type carpet
cleaner with a sponge or brush,
allowing cleaner to work for a few
minutes to loosen dirt. Continue by
rubbing carpet in a circular motion.
Wipe off any excess cleaner with
a clean cloth. If any dirt remains,
repeat process. Best results are
obtained by keeping the carpet as
dry as possible.

EXPLANATION OF MAINTENANCE ITEMS
MAINTENANCE
Scheduled Maintenance Log
Spark Plugs
Replace at specified interval. Install
new plugs of the same type as origi-
nally 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 deterio-
ration, 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.
Wiper Blades
The wiper blades should not show
any signs of cracking, splitting, wear,
contamination or deformation. The
wiper blades should clear the wind-
shield without streaking or skipping.
