Warning function
Light in the exterior mirror
Prewarning
The dimmed light in the exterior mirror indicates
when there are vehicles in the blind spot or ap‐
proaching from behind.
Acute warning
When the turn signal is switched on while a vehi‐
cle is in the critical zone, the steering wheel vi‐
brates briefly and the light in the exterior mirror
flashes brightly.
The warning stops when the other vehicle has
left the critical area or the turn signal has been
deactivated.
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.
