WARNING
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components, etc. to catch fire.
■Precautions regarding the exhaust pipes
Exhaust gasses cause the exhaust pipes to become quite hot.
When washing the vehicle, be careful not to touch the pipes until it has
cooled sufficiently, as touching a hot exhaust pipes can cause burns.
■Precaution regarding the rear bumper with Blind Spot Monitor
If the paint of the rear bumper is chipped or scratched, the system may mal-
function. If this occurs, avoid using the system and consult your Toyota
dealer.

3906-1. Maintenance and care
■Caring for leather areas
Toyota 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 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.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, such as on the floor, in the
hybrid battery (traction battery) air vent, and in the trunk.
Doing so may cause the hybrid battery, electrical components, etc. to mal-
function or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(P. 36)
An electrical malfunction may 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. 366) 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. The instrument panel may reflect
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.
