brush to apply the foam. Rub in overlapping circles. Do not apply water. The excel-
lent results are obtained when keeping the carpet as dry as possible.
nSeat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION
nWater in the vehicle
lDo not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch fire.

tions, dye, bleach or other detergent. Doing so may discolor the vehicle interior or
cause streaks or damage to painted surfaces.
nPreventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of leather
surfaces.
lRemove any dust or dirt on leather surfaces immediately.
lDo not expose the vehicle to direct sunlight for extended periods of time. Park

Maintenance requirements
nRepair and replacement
It is recommended that genuine Lexus parts be used for repair to ensure perfor-
mance of each system. If non-Lexus parts are used in replacement or if a repair
shop other than a Lexus dealer performs repairs, confirm the warranty coverage.
To ensure safe and economical driving, day-to-day care and regular main-
tenance is essential. It is the owner’s responsibility to perform regular
checks. Lexus recommends the following maintenance.
nGeneral maintenance
Should be performed on a daily basis. This can be done by yourself
or by a Lexus dealer.
nScheduled maintenance
Should be performed at specified intervals according to the mainte-
nance schedule.
For details about maintenance items and schedules, refer to the
“Warranty and Services Guide/Owner’s Manual Supplement/
Scheduled Maintenance”.
nDo-it-yourself maintenance
You can perform some maintenance procedures yourself.
Please be aware that do-it-yourself maintenance may affect war-
ranty coverage.
The use of Lexus Repair Manuals is recommended.
For details about warranty coverage, see the separate “Owner’s Guide”,
“Warranty and Services Guide”, “Owner’s Manual Supplement” or
“Warranty Booklet”.
