Kia Optima: Brake system / Hill-start assist control (HAC)
A vehicle has the tendency to roll back on a steep hill when it starts to go after stopping. The Hill-start Assist Control (HAC) prevents the vehicle from rolling back by applying the brakes automatically for about 2 seconds. The brakes are released when the accelerator pedal is depressed or after about 2 seconds.
The HAC is activated only for about 2 seconds, so when the vehicle is starting off always depress the accelerator pedal.
WARNING - Maintaining Brake Pressure on Incline
HAC does not replace the need to apply brakes while stopped on an incline. While stopped, make sure you maintain brake pressure sufficient to prevent your vehicle from rolling backward and causing an accident. Don’t release the brake pedal until you are ready to accelerate forward.
