The Auto Start/Stop function makes sure that fuel is only used when your car is actually driving.
Whilst waiting at traffic lights or in stop-and-go-traffic, the Auto Start/Stop function takes to save fuel by switching off the engine as soon as the car is idling and when you brake to a complete standstill.
A signal in the Info Display indicates that the Auto Stop/Start function is active. As soon as you take your foot off the brake, the engine switches itself back on in a split second so you can continue driving without delay.
The Auto 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 you are turning the steering wheel. 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 Auto Start/Stop function can be switched off at any time with the push of a button.
