• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)

PRIUS +_OM_OM47821E_(EE)
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
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, 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 (traction battery), electrical compo-
nents, etc. to malfunction or catch fire.
Do not get any of the SRS components or wiring in the vehicle interior wet.
(P. 160)
An electrical malfunction may cause the airbags to deploy or not function
properly, 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.
