The function can assist by steering the car back to its own lane.
If the car is about to leave its own lane while another vehicle is in the blind spot, or another vehicle is approaching rapidly in an adjacent lane at the same time, the function can help the driver to steer the car back into its own lane.
The function can even assist if the driver intentionally changes lanes using direction indicators without noticing that another vehicle is approaching.
The function is active within the speed range 60-140 km/h(37-87 mph) on roads with clearly visible lane markings/lines.
After automatic engagement, the driver display indicates that this has occurred via a text message:
- Collision avoidance assistance Automatic intervention
- The "Steering assistance at risk of rear-end collision" subfunction is supplementary driver support intended to improve driving safety – it cannot handle all situations in all traffic, weather and road conditions.
- Steering assistance is only activated if there is a high risk of collision – you must therefore never wait for the function to intervene.
- The function is 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.
