FORD 2013 F-150 v.3 - Manual (Page 220)

WARNING: During all times, you are responsible for controlling
the vehicle, supervising the hill start assist system and
intervening, if required.
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.
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.
