Hill-start assist control (HAC)
HAC is a convenience feature. It is intended is to prevent the vehicle from rolling backwards while driving uphill on an inclined surface. HAC holds the braking pressure for 2 seconds after releasing the brake pedal.
During the pressure-hold period, the driver has enough time to depress the accelerator pedal to drive.
The HAC is activated only for 2 seconds. Use caution to prevent the vehicle from rolling backward and causing an accident with objects or people behind.
-
The HAC will not operate when the transmission shift lever is in the P (Park) or N (Neutral) position.
-
The HAC activates even when the ESC is off, but it does not activate when the ESC has malfunctioned.
