LCS - Lane change support

It is a lane change assist system that controls the rear shadow area on the driver and passenger side, which is not visible from the rearview mirrors. When the driver turns on the turn signal and intends to change lanes, the radar integrated into the LCS system checks for the presence of vehicles in the shade and, if so, warns with a light signal.

The device was developed by Volvo and works in a similar way to Lane Assist.
