■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.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, su ch as on the floor, in the hybrid battery
(traction battery) air vents, and in the luggage compartment.
Doing so may cause the hybrid battery, elec trical components, etc. to malfunction or
catch fire.
