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
brus
h to apply the foam. Rub in overlappin g 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.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid bat-
tery (traction battery) air vents, and in the trunk. 
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. 105) 
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, resulting in death or serious injury.
