FORD 2011 F-150 v.3 - Manual (Page 298)

Brake-shift interlock – floor-shift transmission
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless the brake pedal is pressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal pressed, it is possible that a fuse has
blown or the vehicle’s brake lamps are not operating properly. Refer to
Fuses and relays in the Roadside Emergencies chapter.
If the fuse is not blown and the brake lamps are working properly, the
following procedure will allow you to move the gearshift lever from P
(Park):
1. Apply the parking brake, turn the
ignition key to the off position, and
remove the key.
2. Starting at the rear of the trim
panel, using a screwdriver (or
similar tool) carefully pry up the
trim panel from rear attachments
and disconnect it from the console
to expose the inside of the gearshift.
3. Locate the brake shift interlock
lever on the passenger side of the
shifter assembly.
4. Apply the brake pedal. Using a
screwdriver (or similar tool), press
and hold the brake shift interlock
lever while pulling the gearshift
lever out of the P (Park) position
and into the N (Neutral) position.
5. Install the trim panel.
6. Apply brake pedal, start the vehicle, and release the parking brake.
See your authorized dealer as soon as possible if this procedure
is used.
WARNING: Do not drive your vehicle until you verify that the
brakelamps are working.
