214 Brakes Hill start assist keeps your vehicle stationary long enough to move your foot from the brake pedal to the accelerator pedal when your vehicle is on a slope. 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). Using 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, the hill start assist feature 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 two or 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.
