Help when starting on a hill
4
Hill start assist (HSA ) prevents the car from roll-
ing backwards when starting on an uphill gradi-
ent. When reversing uphill, it prevents the car
from rolling forwards.
The function means that the pedal pressure in
the brake system remains for several seconds
while the driver's foot is moved from brake pedal
to accelerator pedal.
The temporary braking effect releases after sev-
eral seconds or when the driver starts to drive
away.
Hill start assist is available even when the func-
tion for automatic brake when stationary (Auto
hold) is deactivated.
