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.
The lamps in the door mirrors flash during steering intervention, regardless of whether the BLISBlind Spot Information function is activated. An acoustic signal can also be heard.
When the function intervenes, a message is shown in the driver display.
