BRAKE HOLD [G2737981]

WARNING:

The brake hold functions act on all four wheels. Under the specified conditions, the brake hold functions apply the Electric Parking Brake (EPB) automatically on the rear wheels only. On steep or slippery slopes, especially when facing downhill, applying the EPB may cause the vehicle to skid. Re-apply the brake pedal to secure the vehicle. Failure to do so may result in serious injury or death.

CAUTION:

To avoid damage to the vehicle it is recommended to disable all brake hold functions when using an automated car wash that propels the vehicle. Failure to do so could cause damage to the vehicle.

CAUTION:

Take care when using brake hold, there may be some vehicle movement while the function is active. There may be increased vehicle movement during a cold engine start when the idle speed is high. On slippery or loose surfaces such as gravel, there may be some wheel spin or skidding while brake hold is active.

The brake hold functions maintain the vehicle in a standstill position without the brake pedal having to be pressed continuously.

When a brake hold function is active, the instrument panel illuminates the brake hold lamp.

The brake hold functions operate in Reverse (R), Neutral (N), Drive (D) and Sport (S). Brake hold maintains hydraulic brake pressure in the braking system until the accelerator pedal is applied.

The engine may auto stop while the brake hold function is active. When driving away, there is a slight delay after the accelerator is pressed, while the engine restarts.

The brake hold functions release hydraulic brake pressure and apply the EPB and then deactivate if:

  1. The brake hold function has been active for more than 5 minutes.
  2. The driver’s seat belt is unbuckled while a brake hold function is active.
  3. The driver’s door is opened while a brake hold function is active.

The brake hold functions are unavailable if:

  1. The driver’s seat belt is unbuckled or the driver’s door is opened.
  2. If Park (P) is selected.
  3. The EPB is applied. See ELECTRIC PARKING BRAKE (EPB).
  4. Hill Descent Control (HDC) is active.
  5. All Terrain Progress Control (ATPC) is active and the vehicle is being driven downhill.
  6. Adaptive cruise control queue assist is active.
  7. The vehicle's engine is switched off manually.

The brake hold functions do not operate if there is a fault with:

  1. Dynamic Stability Control (DSC).
  2. The braking system.
  3. The EPB system.
Auto hold

The auto hold function applies the brakes automatically to prevent the vehicle rolling back downhill. The auto hold function also holds the vehicle on uphill or downhill gradients whenever it is brought to a stop using the brake pedal.

NOTE:

The auto hold function is unavailable if the vehicle is engaged in N or P.

To disable or re-enable auto hold, touch the vehicle controls icon on the touchscreen driver side bar. See DRIVER SIDE BAR ICONS.

  1. Select DRIVE.
  2. Touch the Autohold soft key.
NOTE:

To disable the auto hold function while it is holding the vehicle on the brakes, press the brake pedal and touch the Autohold soft key.

On demand hold

To activate on demand hold, the vehicle must be at a standstill and the driver must give the brake pedal a quick firm press. On demand can be activated in any gear except P.

On demand hold operates in R, N, D and S and maintains hydraulic brake pressure in the braking system until the accelerator pedal is applied.

NOTE:

On demand hold is still available when auto hold has been disabled via the touchscreen.
