Auto Start Stop Function The engine stops automatically when the vehicle is stopped, e.g. at traffic lights or in a traffic jam, if all preconditions for stopping the engine automatically are met. The engine can also stop automatically during the stopping process while travelling at walking pace. The Auto Start Stop function thus helps to save fuel.
The ignition stays on even when the engine switches off automatically. All safety functions are still available.
On the Panamera GTS, the engine can only be stopped after the vehicle has come to a standstill.
