Driving Assistance PLUS package
General notes
The Active Driving Assistance PLUS package
consists of DISTRONIC PLUS (Y page 185),
Active Blind Spot Assist (Y page 221) and
Active Lane Keeping Assist (Y page 224).
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.
