July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Inertia Switch

The switch is located in the jack storage area on wagon models or spare tire wheel on all other models.

When impact forces exceed the magnetic force that retains the ball, it triggers the contact that opens the electric circuit. When this circuit is opened, the fuel pumps stop.

If the inertia switch is tripped, the engine stops running and cannot be restarted until it is reset. To reset the switch, open the liftgate and fold the floor covering back for access to the spare tire well. Press button on top of the inertia switch.

NOTE: DO NOT reset the inertia switch until the complete fuel system has been inspected for leaks.
