Auto Start-Stop makes sure that fuel is only used when your car is actually being driven. If you’re waiting at traffic lights or in stop-and-go traffic, Auto Start-Stop saves fuel by switching off the engine as soon as the car is idling and you have taken your foot off the clutch (manual transmission), or when you brake to a complete standstill (automatic transmission).
A signal in the Info Display indicates that Auto Stop-Start is active. As soon as you shift into gear (manual transmission) or take your foot off the brake (automatic transmission), the engine switches itself back on in a split second so you can continue driving without delay.
Auto Start-Stop 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 or 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. Auto Start-Stop can be switched off at any time with the push of a button.
