Start/Stop* - the engine auto-starts

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.

An auto-stopped engine may restart in certain cases without the driver having decided that the journey should continue.

In the following cases the engine also starts automatically if the driver has not depressed the clutch pedal (manual gearbox) or takes his/her foot off the brake pedal (automatic gearbox):
