Start/Stop* - the engine does not stop
Some engine and gearbox combinations are equipped with a Start/Stop function which engages in the event of e.g. stationary traffic or waiting at traffic lights.
Although the Start/Stop function is activated, the engine does not always stop automatically.
The engine does not auto-stop if:
