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.
