Driving Assistance Plus package
General notes
The Driving Assistance PLUS package consists
of DISTRONIC PLUS (
Y
page 184), Active Blind
Spot Assist (
Y
page 221) and Active Lane Keep-
ing Assist (
Y
page 223).
Active Blind Spot Assist
General notes
Active Blind Spot Assist monitors the areas on
either side of the vehicle that are not visible to
the driver with two lateral, rear-facing radar sen-
sors. 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 lanes, you will
also receive a visual and audible collision warn-
ing. If a risk of side impact is detected, correc-
tive braking may help you avoid a collision.
Active Blind Spot Assist evaluates the free
space in the direction of travel and to the side
before making a course-correcting brake appli-
cation. 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 rear sen-
sors must not be covered, e.g. by bicycle racks
or overhanging loads. Following a severe impact
or in the event of damage to the bumpers, have
the function of the radar sensors checked at a
qualified specialist workshop. Active Blind Spot
Assist may otherwise no longer function prop-
erly.
