The traffic jam assist is an extension of the active lane assist link►
and uses its functions in conjunction with the functions of the adaptive cruise control link►
. The traffic jam assist can help to keep the vehicle in lane. The system steers the vehicle automatically when the adaptive cruise control is switched on (subject to certain inherent system limitations).
