FORD 2004 F-150 v.5 - Manual (Page 157)

If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed, it is possible that a fuse
has blown or the vehicle’s brakelamps are not operating properly. Refer
to Fuses and relays in the Roadside Emergencies chapter.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to OFF/LOCK, then remove
the key.
2. Locate the round access plug on
the underside of the steering
column cover.
3. Remove the access plug using a flat head screwdriver, then push the
override button using a flat head screwdriver, apply the brake pedal and
shift the transmission into N (Neutral).
4. Reinstall the access plug cover, start the vehicle and release the
parking brake.
Do not drive your vehicle until you verify that the brakelamps
are working.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the OFF/LOCK position
and remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.
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 brake pedal is depressed.
