WARNING
The system does not replace the parking brake. When you leave your vehicle, always apply the parking brake and shift the transmission into park (P) for automatic transmission or first gear for manual transmission.
You must remain in your vehicle when the system turns on. At all times, you are responsible for controlling your vehicle, supervising the system and intervening, if required. Failure to take care may result in the loss of control of your vehicle, serious personal injury or death.
The system turns off if there is a malfunction or if you excessively rev the engine.

The system makes it easier to pull away when your vehicle is on a slope without the need to use the parking brake.
When the system activates, your vehicle remains stationary on a slope for a few seconds after you release the brake pedal. This allows you time to move your foot from the brake to the accelerator pedal. The brakes release when the engine has developed sufficient torque to prevent your 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.
The system activates on any slope that causes your vehicle to roll.
Note:  There is no warning lamp to indicate the system is either on or off.
Using Hill Start Assist
  1. Press the brake pedal to bring your vehicle to a complete standstill. Keep the brake pedal pressed and shift into first gear when facing uphill or reverse (R) when facing downhill.
  1. The system activates if the sensors detect that your vehicle is on a slope.
  1. When you remove your foot from the brake pedal, your vehicle remains on the slope without rolling away for a few seconds. This hold time increases if you are in the process of driving off.
  1. Pull away in the normal manner.
