Inertia Fuel Shutoff Switch: Description and Operation

Crash Fuel Shut-Off

Function

Vehicles with airbags are equipped with a crash fuel shut-off system. It reduces the danger of a fire in a crash as the fuel pump is switched off via the fuel
pump relay.

At the same time, this function improves engine start-up behavior. When opening the door, the fuel pump is activated for 2 seconds to build pressure in
the fuel system.

Observe safety precautions when opening fuel system.
