BMW 3: Warning function
Light in the exterior mirror
Acute warning
If there is a risk of collision, the light in the exterior
mirror flashes and the steering wheel vibrates.
A Check Control message is displayed at
the same time.
If necessary, an active steering intervention then
takes place to prevent collisions and maintain the
vehicle within its own lane.
The steering intervention can be noticed on the
steering wheel and can be manually overridden
at any time.
