Inertia Switch

CAUTION: Do not reset inertia switch until complete fuel system has been inspected for leaks.

In event of collision, electrical contacts in inertia switch will open. This will automatically shut off fuel pump. Fuel pump will shut off even if engine does not stop running. Engine will top shortly due to lack of fuel. It will not be possible to restart engine until inertia switch is manually reset. To reset inertia switch, depress button on top of switch.

On Taurus and Sable station wagon models, switch is located behind access door in right rear cargo area.

On non-wagon models, switch is located behind trim panel in left side of trunk.
