Activating and deactivating the start/stop function

The start/stop function is available when the car is started. When the function is activated, the engine is switched off temporarily. The engine then starts automatically when the function is deactivated or when the car requires this.

Activating the start/stop function

Depress and hold the brake pedal depressed.
The start/stop function is activated and the engine is switched off.

 Note

  • In some cases, the start/stop function is activated before the car is completely stationary.
  • When adaptive cruise control or Pilot Assist is activated, the start/stop function is activated for a few seconds after the car is completely stationary.

 Note

All of the car's normal systems, such as lighting and radio, work normally even when the start/stop function is activated.

However, some equipment may have temporarily reduced function, such as the climate control's fan speed or loudspeaker volume.

Deactivating the start/stop function

Release the brake pedal or gently depress the accelerator pedal.
The start/stop function is deactivated and the engine starts.

 Note

When the start/stop function is activated and:

  • the function for automatic brake when stationary (Auto hold) is activated, start of the engine is delayed until the accelerator pedal is depressed
  • adaptive cruise control or Pilot Assist is activated, the engine starts when the accelerator pedal is depressed or by pressing the P5-1507-Cruise control, speed limiter, activates speed limiter from standby mode symbol 5x3,5 button on the left-hand steering wheel keypad
  • the car is facing uphill, hill start assist (HSA1) engages to prevent the car from rolling backwards
  • the car is facing downhill, release the brake pedal slightly. A small increase in speed starts the engine.
