CAUTION
■
When the vehicle is parked
● Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehi-
cle’s electrical components.
● Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.
● If a curved glass is coated with a metallized film such as a silver-colored
one, reflected sunlight may cause the glass to act as a lens, causing a fire.

SIENNA_OM_OM45472U_(U)
■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.
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. 170)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
■ Cleaning the interior (esp ecially 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.
