Hyundai Accent: Hill-start assist control (HAC)
Hill start Assist Control is a convenience function. The main intent is to prevent the vehicle from rolling backwards while taking off uphill from a stop. HAC holds the braking pressure built up by the driver during stopping for 2 seconds after releasing the brake pedal.
During the pressure-hold period, the driver has enough time to press the accelerator pedal to drive off.
The braking pressure is reduced as soon as the system detects the driver's intention to drive off.
WARNING
The HAC is usually activated only for 2 seconds: If the built-up brake hold pressure is insufficient to hold the vehicle, the driver must quickly activate the brake pedal to prevent the vehicle from rolling backward. Unexpectedly rolling backward could cause an accident, and serious injury.
NOTICE
- The HAC does not operate when the transaxle shift lever is in the P (Park) or N (Neutral) position.
- The HAC activates even though the ESP is off but it does not activate when the ESP has malfunctioned.
