End positionDepending on the size of the parking
space, the vehicle may be positioned at an
angle in the parking space. Advanced Park-

limit of the parking space where possible.
Adjust the end position by maneuver-
ing as needed.
Observe the Park Assist* display
(page 467).Canceling the Advanced Parking
Guidance
Press the Park Assist* button

The Advanced Parking Guidance is im-
mediately canceled and Park Assist* is

Rear View Camera*
The Rear View Camera is an electronic and
visual parking aid. It shows you the area
behind the vehicle on the COMAND dis-
play.
In addition, the Rear View Camera contains
guide lines to help you with driving in re-
verse.
The area behind the vehicle is displayed as
a reverse-mirror image similar to the view

Please note that objects which do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck, may appear to be further
away than they actually are. In this case, you
should not use the guide lines to judge dis-
tance. The use of the guide lines to judge
distance increases the risk of impacting the
objects.
Warning!

The Rear View Camera is a supplement sys-
tem. It is not intended to, nor does it re-
place, the need for extreme care. The
responsibility during parking and other driv-
ing maneuvers always remains with the driv-
er.
The Rear View Camera may show obstacles
with a distorted perspective, incorrectly or

Blind Spot Assist*
Depending on production date, your vehi-
cle may not be equipped with this feature.
Blind Spot Assist uses radar sensors to
monitor the area on both sides of your ve-
hicle. It will assist you when you change
lanes driving at speeds of above 20 mph
(30 km/h). A warning will appear on the
outside rear view mirror as soon as anoth-
er vehicle is detected in the area being
monitored. If you then activate the corre-
sponding turn signals to change lanes, you
will see and hear a collision warning. Blind
Spot Assist operates using two sensors in
the front bumper and four sensors in the
rear bumper.In order for Blind Spot Assist to function,
the radar sensors must be switched on and
operational.
When travelling in Canada in a vehicle not
registered in Canada, you must switch off
the radar sensor system* (
page 302).
Canadian law does not permit the use of
the radar sensor system* (
page 302) for
vehicles from outside of Canada. When you
switch off the radar sensor system*, the
following functions are deactivated:
BAS Plus* (
page 68)

Warning!
G
Blind Spot Assist is only a driving aid and
may not detect all vehicles. It is the driver’s
responsibility at all times to be attentive to
road, weather and traffic conditions and to
provide the steering, braking and other
driving inputs necessary to retain control of
the vehicle. Failure to do so could result in
recognizing dangers too late, possibly re-
sulting in an accident and serious injury to
yourself and others.
Warning!
G
Blind Spot Assist cannot detect road and
traffic conditions.
Blind Spot Assist may not be able to detect
narrow vehicles such as motorcycles or bi-
cycles, or it may not detect them until it is
too late.
The monitoring function may be impaired if
your sensors are dirty, subject to heavy
spray, or if visibility is poor due to e.g. snow,
rain, or fog. This can result in vehicles not
being detected or being detected too late.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle. Failure to do so could
result in recognizing dangers too late, possi-
bly resulting in an accident and serious inju-
ry to yourself and others.
