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.
Depending on settings, lane assistance acts in accordance with the following:
- Assist activated: 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.
- Warning activated: If the car is about to cross a lane line, the driver is warned by means of vibrations in the steering wheel.
When a direction indicator/flasher is switched on, there are no steering corrections or alerts from lane assistance.
- The function is supplementary driver support intended to facilitate driving and make it safer – it cannot handle all situations in all traffic, weather and road conditions.
- The driver is advised to read all sections in the Owner's Manual that relate to this function to learn about factors such as its limitations and what the driver should be aware of before using the system.
- Driver support functions are not a substitute for the driver's attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
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 cutting bends.
