Auto Start Stop is a function that lets you save fuel by turning off the engine at idle. If activated and you stop at a traffic light with your foot on the brake pedal, for example, the Auto Start Stop function can automatically turn off the engine. This fuel-saving feature restarts the engine as soon as you release the brake pedal, once the light turns green.

Key advantages are that there is no need for you to change your driving habits, and the function can be activated/deactivated by the push of a button. You can simply drive the way you are used to. In addition, all audio and communication systems, as well as heating and cooling, remain on, despite the engine being turned off. This ensures that your level of comfort is maintained.

The Auto Start Stop function can be activated and deactivated using a separate button. The function may remain inactive under particular circumstances, e.g., very high outside temperatures, on extreme uphill gradients, or if battery charge is low. The starter has been modified to meet the increased requirements demanded by this function, and the battery is continuously monitored for the level of charge and condition. The battery and starter are consumable components and are subject to an increased rate of wear in the event of frequent engine stopping.
