Rollover Valve: Description and Operation

Crash Fuel Disengagement

Function

Vehicles with airbag from model year 2000 have crash-fuel disengagement. This system reduces the danger of fuel leakage after a crash by switching off
the fuel pump with the fuel pump relay. Also, the system causes the fuel pump to turn on for 2 seconds when the door is opened, and with it the fuel
pressure comes up in the fuel system.

If fuel system must be opened:
Observe safety precautions.
