Start/stop system

Start/Stop* - the engine auto-starts

Updated 7/23/2018

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.
