Hill Hold Control (HHC)

Chapter 4 · Manual page 213

It is impossible for HHC keep the vehicle in a standstill state under all circumstances (e.g. slippery ground, snow and ice, etc.) when going uphill. The driver must always pay attention to the vehicle conditions.

With the HHC in action, the driver is strictly prohibited from leaving the vehicle, otherwise serious accidents may occur.

During a hill start under a stop-and-go road condition, please press the brake pedal strongly for several seconds before each start. HHC assists the driver by holding the vehicle during hill starts. If the driver releases the brake pedal, the HHC will hold the vehicle stationary for a short time. HHC will be activated when the following conditions are met at the same time:

  1. Close the driver side door and fasten the seat belt.
  2. The vehicle is steadily brought to a stop on a slope.
  3. SCS is fault free.
  4. EPB is released and fault free.
  5. The vehicle is READY mode.
  6. The vehicle is in D or R gear.
  7. Sufficient force has been applied to the brake pedal before start-off.

When the vehicle is reversing upward on the slope, the HHC also works.
