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 at the same time as the steering input. An acoustic signal can also be heard.
When the function intervenes, a message is shown in the driver display.
Warning
Warnings and steering assistance due to an impending collision always come very late.
Note
This function uses the car's camera and radar units, which have certain general limitations.
