Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.
Turn the engine switch to the ACC or LOCK position.
Restart 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.
To minimize the risk of fuel leakage when the engine stalls or an air-
bag inflates upon collision, the fuel pump shut off system stops sup-
plying fuel to the engine.
