Hyundai Palisade (LX2): 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 an incline. The HAC activates only for approximately 2 seconds.
NOTICE
- The HAC does not operate when the vehicle is shifted to 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.
The Vehicle Stability Management (VSM) is a function of the Electronic Stability Control (ESC) system. It helps ensure the vehicle stays stable when accelerating or braking suddenly on wet, slippery and rough roads where traction over the four tires can suddenly become uneven.
The Downhill Brake Control (DBC) feature assists the driver to descend down a steep hill without having to depress the brake pedal. The system automatically applies the brakes to maintain the vehicle speed below a certain speed and allows the driver to concentrate on steering the vehicle down hill.
