Maintenance and care
RX450h_RX450hL_U
■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 overlapp ing 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.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, su ch as on the floor, in the hybrid battery
(traction battery) air vents, and in the luggage compartment.
Doing so may cause the hybrid battery, elec trical components, etc. to malfunction or
catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet. (P. 38)
An electrical malfunction ma y cause the airbags to deploy or not function properly,
resulting in death or serious injury.
●Vehicles with wireless charger:
Do not let the wireless charger ( P. 549) get wet. Failure to do so may cause the
charger to become hot and cause burns or could cause electric shock resulting in
death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. Th e instrument panel may reflect off the wind-
shield, obstructing the driver’s view and le ading to an accident, resulting in death or
serious injury.

Do not wash the vehicle floor with water.
Vehicle systems such as the audio system ma y be damaged if water comes into contact
with electrical components such as the au dio system above or under the floor of the
