What is Lane Keeping Assist?

A windscreen camera detects lane markings. Lane departure warning only warns; lane keeping assist also steers. Lane centring keeps the car in the middle of the lane. The system usually switches off below a certain speed and when the indicator is used, and it warns if the driver's hands are not detected on the wheel.

How it works

The system calculates the car's position and applies small steering corrections through the electric steering.

Why it matters for your car

Worn markings, rain or glare reduce performance. The camera must be calibrated after windscreen replacement.
