6384-1. Maintenance and care
■
Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain 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 overlappin g circles. Do not apply water. 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.
CAUTION■
Water in the vehicle ●
Do not splash or spill liquid in the vehicl e, such as on the floor and in the hybrid
battery (traction battery) air vents or in the luggage compartment.
Doing so may cause the hybr id battery, electrical components, etc. to malfunc-
tion or catch fire.●
Do not get any of the SRS components or wiring in the vehicle interior wet.
(  P. 1 3 4 )
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, resulting in death or severe injury.■
Cleaning the interior (especially instrument panel)

windshield, obstructing the driver's view and leading to an accident, resulting in
death or serious injury.
