■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.
■Front side windows with UV protective coating
The front side windows have UV protective coating. To prevent any damage to the UV
protective coating, observe the following:
●If the windows are dirty, gently wipe them with a cloth soaked in water or lukewarm
water as soon as possible.
●If the windows are very dirty, do not open and close them repeatedly.
WA R N I N G
■Wa t e r i n t h e v e h i c l e
●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid battery
(traction battery) air vents, and in the luggage compartment.
Doing so may cause the hybrid battery, electrical components, etc. to malfunction or
catch fire.

An electrical malfunction may cause the airbags to deploy or not function properly,
resulting in death or serious injury.

shield, obstructing the driver’s view and leading to an accident, resulting in death or
serious injury.
