Vehicles with side collision
mitigation
When there is no response to the vibration of the
steering wheel at speeds of up to
130 mph/210 km/h and the lane marking is
crossed, the system intervenes with a brief active
steering intervention. The steering intervention
helps return the vehicle into the lane. The steer‐
ing intervention can be noticed on the steering
wheel and can be manually overridden at any
time.
Flashing of the light
A flashing of the light during vehicle unlocking
serves as system self-test.
