Lane assistance
The function of the Lane Keeping Aid (LKA) is to help the driver to reduce the risk of the car accidentally leaving its own lane on motorways and similar major routes.Lane Keeping Aid steers the car back into its lane and/or alerts the driver with vibrations in the steering wheel.Lane Keeping Aid is active within the speed range 65–200 km/h (40–125 mph) on roads with clearly visible side lines.On narrow roads the function may be unavailable, in which case it goes into standby mode. The function becomes available again when the road is wide enough.
A camera reads the side lines of the road/lane.
Lane assistance steers the car back into its lane.
Lane assistance warns with steering wheel vibrations.
Lane assistance acts as follows:
- When the car is approaching a lane line, the function will actively steer the car back into its lane by applying a slight torque to the steering wheel.
- If the car is about to cross a lane line, the driver is warned by means of vibrations in the steering wheel.
Note
When a direction indicator/flasher is switched on, there are no steering corrections or alerts from lane assistance.

Lane assistance does not intervene
Lane assistance does not engage on sharp inside curves.In some situations, lane assistance allows lane lines to be crossed without intervening with either steering assistance or a warning – e.g. when using the direction indicators or if the car is allowed to cut the corners in bends.

Difference between Pilot Assist and lane assistance
Pilot Assist is a comfort function that can help you to keep your car within its own lane and maintain a safe distance from vehicles in front of you. Lane assistance is a function which, in a similar way, can help you in some situations to reduce the risk of your car accidentally leaving its own lane.
Pilot Assist with steering assistance
Pilot Assist can help you to steer your car between the lane’s markings, as well as maintaining a preset speed and time interval to the vehicle ahead. The function can also help to maintain an advantageous position in the lane using the lane’s lane lines.
