Hill-start Assist Control (HAC)
A vehicle has the tendency to roll backward when it starts moving after you have stopped it on a steep hill. The HAC system prevents your vehicle from rolling backward by engaging the brakes automatically for about 2 seconds.
The HAC system releases the brakes after about 2 seconds, or when you engage the accelerator pedal.
The HAC system activates for about 2 seconds, so when you start your vehicle, always engage the accelerator pedal.
Maintaining brake pressure on an incline
HAC does not replace the need to engage the brake pedal when you are stopped on an incline. While stopped, make sure you maintain sufficient brake pressure to prevent your vehicle from rolling backward and causing an accident. Do not release the brake pedal until you are ready to accelerate.
