Kia Rio: Brake system / Hill-start assist control (HAC)
The Hill-start Assist Control (HAC) is designed to prevent 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.
CAUTION
- The HAC does not operate when the transmission shift lever is in the
P (Park) or N (Neutral) position.
- The HAC activates even though the ESC is off but it does not activate
when the ESC has malfunctioned.
When driving
It’s a good idea to keep the ESC turned on for daily driving whenever possible.
To turn ESC off while driving, press the ESC OFF button while driving on
a flat road surface.
