HILL-START ASSIST CONTROL (HAC)*

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

The HAC automatically activates whether the ESC is OFF or ON but does NOT activate when the ESC has malfunctioned.

Quick Tips:

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

Reminders:

  • HAC does not operate when the gear shift is in the Park or the Neutral position 
  • HAC does not replace the need to apply brakes while the vehicle is stopped on an incline 
  • In the event of HAC system malfunction, see an Authorized Kia Dealer for service
