Hill start assist (HSA) system
The hill start assist system makes it easier to pull away when the vehicle
is on a slope without the need to use the parking brake. When hill start
assist is active, the vehicle will remain stationary on the slope for up 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 when reversing uphill into a
parking space.
WARNING:
The hill start assist 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
Hill start assist is activated automatically when the vehicle is stopped on
a slope greater than five degrees. Hill start assist operates with the
vehicle facing downhill if reverse gear is selected.
WARNING:
You must remain in the vehicle once you have
activated hill start assist.
Activating 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, hill start assist 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 up to 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.
WARNING:
If the engine is revved excessively, or if a
malfunction is detected when hill start assist is active, hill start
assist will be deactivated.
