What is Lane Change Assist?

It extends blind spot monitoring to fast vehicles approaching from behind. It usually warns with a light in the mirror and a sound or vibration. Some systems can also complete the lane change with steering assistance. Systems may switch off when a trailer is attached unless the car knows its length.

How it works

Rear radar sensors measure the distance and speed of vehicles in adjacent lanes.

Why it matters for your car

Always check mirrors and look over the shoulder. Dirt, snow or a bike rack can block the sensors.
