Maintenance and care
■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-
