injury in the event of a collision.
Do not attempt to service,
repair, or modify the Air
Bag Supplemental Restraint
System or its fuses. See your
Ford or Lincoln-Mercury dealer.

TRANSMISSION OPERATION

Brake-shift interlock
This vehicle is equipped with a
brake-shift interlock feature that
prevents the gearshift from being
moved from P (Park) unless the
brake pedal is depressed.
If you cannot move the gearshift
out of P (Park) with the brake
pedal depressed:
1. Apply the parking brake, turn
ignition key to LOCK, then remove
the key.
2. Insert the key and turn it to
OFF. Apply the brake pedal and
shift to N (Neutral).
3. Start the vehicle.
If it is necessary to use the above
procedure to move the gearshift, it
is possible that a fuse has blown
and the vehicle’s brakelamps may
not be operating properly. Refer to
Fuses and relays
in the
Roadside
emergencies
chapter.
Do not drive your vehicle
until you verify that the
brakelamps are working.
If your vehicle gets stuck in mud
or snow it may be rocked out by
shifting from forward and reverse
gears in a steady pattern. Press
lightly on the accelerator in each
gear.
Driving
104
seconds and return the key to the
OFF position.
5. Make a further check for leaks
in the fuel system.
The fuel pump shut-off switch is
located in the passenger’s foot
well, behind the kick panel.
