Fuel pump shut off system
Follow the procedure below to restart the engine after the system is activated.Turn the engine switch to ACCESSORY mode or turn it 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 the 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.

nol.

could contain more than 15% ethanol, includ-
ing from any pump labeled E30, E50, E85

taining more than 15% ethanol).DO NOT use gasoline con-
