HILL-START ASSIST CONTROL (HAC)*

The HAC system is designed to help prevent the vehicle from rolling backward when accelerating from a stop while on a steep incline.

The HAC system automatically activates whether the ESC is OFF or ON.

Quick Tips:

When HAC is active (e.g., accelerating from a stop on an incline), you may notice that the brakes will momentarily remain engaged after you depress the accelerator. This is normal HAC operation
HAC provides a two-second delay before the vehicle may start rolling backward

Reminders:

The HAC system does not operate when the Gear Shift is in the Park or Neutral position
In the event of an HAC system malfunction, see an authorized Kia dealer for service
HAC does not replace the need to apply brakes while the vehicle is stopped on an incline
