Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehi-
cle, to monitor the area to the sides of the
vehicle which the driver is unable to see. A
warning display in the exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lane, you
will also receive an optical and audible warn-
ing. If a risk of lateral collision is detected,
corrective braking may help you avoid a col-
lision. Active Blind Spot Assist evaluates the
free space in the direction of travel and to the
side before making a course-correcting brake
application. For this, Active Blind Spot Assist
uses radar sensors which are pointed in the
direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
Important safety notes
Active Blind Spot Assist is only an aid and is
not a substitute for attentive driving.
