4046-1. 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. U se 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 obt ained 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 cut s.
■ When cleaning the carpeted portions of the console box, etc.
If a strong adhesive tape is used, there is a possibility that the surface of the
carpet could be damaged.
WARNING
■ 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 i nterior wet.
( P. 42)
An electrical malfunction may cause the airbags to deploy or no t 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 m ay reflect
off the windshield, obstructing the driver’s view and leading t o an accident,
resulting in death or serious injury.

4827-2. Steps to take in an emergency
Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.
Turn the engine switch to ACC or OFF.
Restart the engine.
To minimize the risk of fuel leakage when the engine stalls or
when an airbag inflates upon collision, the fuel pump shut off
system stops supply of fuel to the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.
