V90 Activating and deactivating the start/stop function

Activating the start/stop function

For cars with automatic gearbox:

Depress and hold the brake pedal depressed.

The start/stop function is activated and the engine is switched off.

In Comfort or Eco drive mode, 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.

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.

For cars with automatic gearbox:

Release the brake pedal or gently depress the accelerator pedal.

The start/stop function is deactivated and the engine starts.

When the start/stop function is deactivated and:

the function for automatic braking 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 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.

The centre display shows whether the function is available or deactivated.

Illuminated indication: the start/stop function is available.

The driver display's tachometer indicates when the start/stop function is available, active or unavailable.
