■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to maintain
the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or brush to
apply the foam. Rub in overlapping circles. Do not use water. Wipe dirty surfaces and let
them dry. Excellent results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the belts
periodically for excessive wear, fraying or cuts.
■When cleaning the carpeted portions of the glove box, console box, etc.
If a strong adhesive tape is used, there is a possibility that the surface of the carpet could
be damaged.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(  P. 37)
An electrical malfunction may cause the airbags to deploy or not function properly,
resulting in death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. Th e instrument panel may reflect off the wind-
shield, obstructing the driver’s view and leading to an accident, resulting in death or
serious injury.
