FORD 2011 F-150 v.1 - Manual (Page 289)

Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.
WARNING: Vehicles with a higher center of gravity such as
utility vehicles and trucks handle differently than vehicles with a
lower center of gravity. Utility vehicles and trucks are not designed for
cornering at speeds as high as passenger cars any more than low-slung
sports cars are designed to perform satisfactorily under off-road
conditions. Avoid sharp turns, excessive speed or abrupt maneuvers in
these vehicles. Failure to drive cautiously could result in an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death.
WARNING: Loaded vehicles, with a higher center of gravity,
may handle differently than unloaded vehicles. Do not overload
your vehicle and use extra precautions, such as driving at slower
speeds, avoiding abrupt steering changes and allowing for increased
stopping distance, when driving a heavily loaded vehicle. Over-loading
or loading the vehicle improperly can deteriorate handling capability
and contribute to loss of vehicle control and vehicle rollover.
BRAKE-SHIFT INTERLOCK - COLUMN-SHIFT TRANSMISSION
This vehicle is equipped with a park/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, perform the following procedure:
Note: The following procedure is easier to perform when the steering
column is adjusted to the full up position. Refer to Tilt steering wheel in
the Driver Controls chapter.
1. Apply the parking brake, turn the ignition to the off position, then
remove the key.
