Lane Keeping Aid

Updated 2021-10-04

Lane Keeping Aid (LKA1) is designed to actively steer the vehicle on freeways, highways and other major roads to help the driver reduce the risk of the vehicle unintentionally veering out of the lane.

Lake Keeping Aid steers the vehicle back into the lane and/or alerts the driver using vibrations in the steering wheel.

Lane Keeping Aid is active at speeds between 65–200 km/h (40–125 mph) on roads with clearly visible traffic lane marker lines.

On narrow roads, the function may be unavailable and go into standby mode. The function will become available again when the road becomes sufficiently wide.
