When washing the vehicle, be careful not to touch the pipe until it has cooled suffi-
ciently, as touching a hot exhaust pipe can cause burns.

NOTICE
■To prevent paint deterioration and corrosion on the body and components (alu-

■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 overlapping circles. Do not apply water. 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.
Doing so may cause electrical components etc. to malfunction or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(→ P. 9 8 )
Electrical malfunction may cause the airbags to deploy or not function properly,
resulting in death or severe injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the
windshield, obstructing the driver's view and leading to an accident, resulting in
death or serious injury.
