Lane Keeping Assist.

Lane Keeping Assist helps to prevent accidents caused by leaving your lane unintentionally. 

Depending on the desired operating mode, Lane Keeping Assist is active from a speed of around 60 km/h.

A multifunction camera recognises road markings and detects whether the vehicle is travelling in its own lane. If the vehicle leaves its lane unintentionally, Lane Keeping Assist gives the driver a haptic warning that it’s about to stray unsafely.
Lane Keeping Assist is standard equipment on the V-Class V 220 d and  V-Class V 250 d AVANTGARDE.
