Hyundai Elantra: Braking System / Hill-Start Assist Control (HAC)

The Hill-Start Assist Control (HAC) helps prevent the vehicle from rolling backwards when starting a vehicle from a stop on a hill. The system operates the brakes automatically for approximately 2 seconds and releases the brake after 2 seconds or when the accelerator pedal is depressed.

WARNING

Always be ready to depress the accelerator pedal when starting off on a incline. The HAC activates only for approximately 2 seconds.

NOTICE

• The HAC does not operate when the shift lever is in P (Park) or N (Neutral)
• The HAC activates even though the ESC (Electronic Stability Control) is off but does not activate when the ESC has malfunctioned.
