FORD 2012 F-150 Raptor v.3 - Manual (Page 310)

WARNING: If the engine is revved excessively, or if a
malfunction is detected when the hill start assist feature is
active, the hill start assist feature will be deactivated.
Note: This feature will not operate if the parking brake is activated.
Hill start assist keeps your vehicle stationary long enough to move your
foot from the brake pedal to the accelerator pedal when your vehicle is
on a slope.
The brakes are released automatically once the engine has developed
sufficient drive to prevent the vehicle from rolling down the slope. This
is an advantage when pulling away on a slope, (for example from a car
park ramp, traffic lights or when reversing uphill into a parking space).
Using Hill Start Assist
1. Press the brake pedal to bring the vehicle to a complete standstill.
Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, the hill start assist
feature will be activated automatically.
3. When you remove your foot from the brake pedal, the vehicle will
remain on the slope without rolling away for approximately two or three
seconds. This hold time will automatically be extended if you are in the
process of driving off.
4. Drive off in the normal manner. The brakes will be released
automatically.
If Your Vehicle Gets Stuck in Mud or Snow
Note: Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note: Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
