Maintenance and care
■Caring for leather areas
Toyota 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 keep-
ing 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.
Doing so may cause electrical components, etc., to malfunction or catch
fire.
