■Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause damage to the
rear window defogger heater wires. Use a cloth dampened with lukewarm water to
gently wipe the window clean. Wipe the window in strokes running parallel to the
heater wires.
■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. The excel-
lent 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.
CAUTION

●Be careful not to splash or spill liquid on the floor.
●Do not splash water on the electric comp onents in the engine compartment. This
may cause the malfunction of the electric components.
●Do not get any of the SRS components or wiring in the vehicle interior wet. 
