Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces
Parking tips:
R On narrow roads, drive as close to the park-
ing space as possible.
R Parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
R Parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 226 )warning messages during the
parking procedure.
R At any time, you can intervene in the steer-
ing procedure to correct it. Active Parking
Assist will then be canceled.
R When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R Never use Active Parking Assist when snow
chains are installed.
R Make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. G
WARNING
If there are objects above the detection range, Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (Y page 225).
Active Parking Assist does not support you
with parking spaces parallel to the direction
of travel if:
R the parking space is on a curb
R the system reads the parking space as
being blocked, for example by foliage or
grass paving blocks
R the area is too small for the vehicle to
maneuver into
R the parking space is bordered by an obsta-
cle, e.g. a tree, a post or a trailer 0043

Towing a trailer For vehicles with a trailer tow hitch, the min-
imum length for parking spaces is slightly
increased. If you have attached a trailer to your vehicle,
you should not use Active Parking Assist.
Once the electrical connection is established
between your vehicle and the trailer, Active
Parking Assist is no longer available. PARK-
TRONIC is deactivated for the rear area. Rear view camera
General notes Rear view camera
0043is in the handle on the
tailgate.
Rear view camera 0043is an optical parking and
maneuvering 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 rear view camera messages in the COMAND
display.
Important safety notes The rear view camera is only an aid. It is not a
replacement for your attention to your imme- diate surroundings. You are always responsi-
ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there are no persons, animals or objects in the area
in which you are maneuvering. 232

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
event, have the camera position and setting checked at a qualified specialist workshop
The field of vision and other functions of the

General notes The 360° camera is a system consisting of
four cameras.
The system analyzes images from the follow-
ing cameras:
R Rear view camera
R Front camera
R Two cameras in the exterior rear view mir-
rors
The cameras capture the immediate sur-
roundings of the vehicle. The system sup-
ports you, e.g. when parking or if vision is
restricted at an exit.
The 360° camera images can be shown in full
screen mode or in seven different split-screen views on the COMAND display. A split-screenview also includes a top view of the vehicle.
This view is calculated from the data supplied
by the installed cameras (virtual camera).
The seven split-screen views are: R top view and picture from the rear view
camera (130° viewing angle)
R top view and picture from the front camera
(without displaying the maximum steering
wheel angle)
R top view and enlarged rear view
R top view and enlarged front view
R top view and trailer view (vehicles with
trailer tow hitch) R
top view and rear-view images from the
exterior mirror cameras (rear wheel view)
R top view and forward-view images from the
exterior mirror cameras (front wheel view)
i The top view and trailer view are available
for vehicles equipped with a trailer tow
hitch.
When the function is active and you shift the
transmission from position Dor Rto N, you
see the previous view in the COMAND dis-
play. The dynamic guidelines are hidden.
When you change between transmission
positions Dand R, you see the previously
selected front or rear view.
Important safety notes The 360° camera is only an aid. It is not a
replacement for your attention to your imme-
diate surroundings. You are always responsi- ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there are no persons, animals or objects in the area
in which you are maneuvering.
The 360° camera may show a distorted view of obstacles, show them incorrectly or not at
all. It cannot show objects in the following
areas:
R under the front bumper
R very close to the front bumper
R very close to the rear bumper
R under the rear bumper
R in close range above the handle on the
trunk lid
R very close to the exterior mirrors
You are always responsible for safety, and
must always pay attention to your surround-
ings when parking and maneuvering. This
applies to the areas behind, in front of and
beside the vehicle. You could otherwise
endanger yourself and others.
The 360° camera will not function or will
function in a limited manner:
R if the doors are open
R if the exterior mirrors are folded in Driving systems
