FORD 2012 Fiesta v.2 - Manual (Page 251)

HILL START ASSIST (HSA) SYSTEM (IF EQUIPPED)
The hill start assist (HSA) system makes it easier to pull away when the
vehicle is on a slope without the need to use the parking brake. When
HSA is active, the vehicle will remain stationary on the slope for two to
three seconds after you release the brake pedal. During this time, you
have time to move your foot from the brake to the accelerator pedal and
pull away. 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 while in reverse traveling uphill
into a parking space).
WARNING: HSA does not replace the parking brake. When you
leave the vehicle, always apply the parking brake and select P
(Park) (automatic transmission) or neutral (manual transmission).
Using HSA
The HSA system is activated automatically when the vehicle is stopped
on a slope greater than four degrees. HSA operates with the vehicle
facing downhill if reverse gear is selected.
WARNING: You must remain in the vehicle once you have
activated HSA.
WARNING: During all times you are responsible for controlling
the vehicle, supervising the HSA system and intervening, if
required.
Activating HSA
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 HSA system
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 to three
seconds. This hold time will automatically be extended if you are in the
process of driving off.
