Lane Assist can tell when you stray from a lane unintentionally. This system works in conjunction with a camera to recognise lane markings on the road, including yellow lines during roadworks, traffic cones, and other roadside or lane borders. The enhanced “Adaptive” variant (only available as part of Travel Assist) means that the system intervenes in an attempt to keep the vehicle in the selected track within the traffic lane, and the car does not “weave”.
