The concept

The Auto Start/Stop function helps save fuel.

The system switches off the engine during a stop, e.g., in a traffic congestion or at traffic lights. The ignition remains switched on. The engine starts again automatically for driving off.

Certain vehicle components may experience additional wear as a result of this system.
