PRINCIPLE OF OPERATION
The system makes it easier to pull away
when the vehicle is on a slope without the
need to use the parking brake.
When the system is active, the vehicle will
remain stationary on the slope for a short
time 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 when
reversing uphill into a parking space.
WARNING
The system does not replace the
parking brake. When you leave the
vehicle, always apply the parking
brake and select first or reverse gear.
USING HILL START ASSIST
The system is activated automatically
when you stop your vehicle on a slope
greater than 3%. The system operates
with the vehicle facing downhill if reverse
gear is selected and with the vehicle
facing uphill if any forward gear is
selected.
