The Automatic Start/Stop function makes sure that fuel is only used when the car is actually driving. When the vehicle comes to a temporary standstill, for example at traffic lights or in stop-and-go traffic, the Automatic Start/Stop function saves fuel by switching off the engine as soon as the car is idling and the foot is off the clutch (manual transmission), or when the car brakes to a complete standstill (automatic transmission).
A signal in the Info Display indicates that the Automatic Start/Stop function is active. As soon as the clutch is pressed (manual transmission) or the foot taken from the brake (automatic transmission), the engine turns itself back on automatically.
The Automatic Start/Stop function never compromises driving comfort and safety, as it remains inactive if the engine has not reached its ideal running temperature, the interior has not yet been sufficiently heated/cooled, if the battery level is too low or if the steering wheel is being turned. A central control unit restarts the engine if required, even when the car is at a standstill. For example, if the car starts to roll forward or if the windscreen becomes foggy. The Automatic Start/Stop function can be switched off at any time with the push of a button.
