Help when starting on a hill
Hill start assist (HSA1) prevents the car from rolling backwards when starting on an uphill gradient. 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 several seconds or when the driver starts to drive away.
The Hill Start Assist is activated when stopping on a sleep slope. The function is available even when the automatic braking when stationary (Auto hold) function is deactivated.
