General notes Reversing camera
:is in the boot lid handle.
Reversing camera :is an optical parking
and manoeuvring aid. It shows the area behind your vehicle with guide lines in the
COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text of messages shown in the
COMAND display depends on the language
setting. The following are examples of
reversing camera messages in the
COMAND display.
Important safety notes The reversing camera is only an aid. It is not a
substitute for your attention to the immediate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals
or objects in range while manoeuvring and
parking.
Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R if the tailgate is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In this
case, have the camera position and setting checked at a qualified specialist workshop.
The field of vision and other functions of the
reversing camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. licence plate holder, bicycle rack). Driving systems

General notes The Active Driving Assistance package con-
sists of DISTRONIC PLUS (Y page 185), Active
Blind Spot Assist (Y page 220) and Active
Lane Keeping Assist (Y page 223).
Active Blind Spot Assist General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the area to the sides of
your vehicle which are behind the driver. 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 an optical and audible colli-
sion warning. If a risk of side impact is detec- ted, corrective braking may help you avoid a
collision. To support the course-correcting
brake application, Active Blind Spot Assist
also uses the forward-facing radar sensor sys-
tem.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be operational.
Important safety notes
Active Blind Spot Assist is only an aid. It may fail to detect some vehicles and is no substi-
tute for attentive driving. 220
