The Hill-Start Assist Control (HAC) helps prevent the vehicle from rolling backwards when starting a vehicle from a stop on a hill. The system operates the brakes automatically for approximately 2 seconds and releases the brake after 2 seconds or when the accelerator pedal is depressed.
WARNING
Always be ready to depress the accelerator pedal when starting off on a incline. The HAC activates only for approximately 2 seconds.
