Driving Assistance Plus package
General notes
The Driving Assistance Plus package consists of
Distance Pilot DISTRONIC (
Y
page 184), Active
Blind Spot Assist (
Y
page 222) and Active Lane
Keeping Assist (
Y
page 224).
Active Blind Spot Assist
General notes
Active Blind Spot Assist monitors the areas on
either side of the vehicle that are not directly
visible to the driver with two lateral, rear-facing
radar sensors. A warning lamp lights up in the
exterior mirrors and draws your attention to
vehicles detected in the monitored area. If you
then switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible collision warning. If a risk of side impact
is detected, corrective braking may help you
avoid a collision. Active Blind Spot Assist eval-
uates the free space in the direction of travel
and to the side before making a course-correct-
ing brake application. For this, Active Blind Spot
Assist uses the forward-facing radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes
Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving.
G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R
overtaking too closely on the side, placing
them in the blind spot area
R
if the difference in the speed of approach
and overtaking is too great
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side
of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are
integrated into the front and rear bumpers and
behind a cover in the radiator trim. Make sure
that the bumpers and the cover in the radiator
trim are free of dirt, ice or slush. The sensors
must not be covered, e.g. by cycle racks or over-
hanging loads. Following an accident or in the
event of damage to the bumpers, have the func-
tion of the radar sensors checked at a qualified
specialist workshop. Active Blind Spot Assist
might otherwise no longer function properly.

G
WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance to the side for other traffic or obstacles.
