A vehicle has the tendency to slip back on a steep hill when it starts to go after stopping. The Hill-start Assist Control (HAC) prevents the vehicle from slipping back by operating the brakes automatically for about 1~2 seconds. The brakes are released when the accelerator pedal is depressed or after about 1~2 seconds.
WARNING
The HAC is activated only for about 1~2 seconds, so when the vehicle is starting off always depress the accelerator pedal.
