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

Important safety notes G
WARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for- wards, e.g. when braking suddenly or in the
event of an accident.
R The vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
R Objects or loads in the trunk/cargo com-
partment cannot be restrained by the seat
backrest.
There is an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged.
! Release and fold the seat cushion
upwards before folding the rear bench seat forward. Otherwise, the backrests may be
damaged.
When the backrest is folded forwards, the
front seats cannot be moved to their rear-
most position. Otherwise, the front seats
and the rear bench seat could be damaged.
Observe the loading guidelines (Y page 342).
The left-hand and right-hand backrests in the
second row of seats can be folded forwards
separately to increase the cargo compart-
ment capacity.
On vehicles with a 3rd row of seats, you must
fold down the 3rd row of seats beforehand
(Y page 111) to obtain maximum cargo com-
partment enlargement.
Folding the rear bench seat forwards !
The backrest is heavy. Therefore, take
care when folding it down. Make sure that
the head restraints are pushed all the way
in so that the backrests and seat cushions
are not damaged. i
If the driver's or front-passenger seat is
set for a larger person, it may not be pos-
sible to fold the rear bench seat forwards.
In this case, move the front seats as far
forward as possible.
X Move the head restraints to the lowest
position (Y page 110).
X Pull release loop 0043of seat cushion 0044.

Important safety notes G
WARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character- istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired. There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
! Mercedes-Benz recommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benz vehicles.
This helps to prevent damage to the vehi-
cle. Position the load on the roof carrier in such
a way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is instal-
led you can:
R raise the sliding sunroof fully
R open the panorama roof with power tilt/
sliding panel fully
R open the tailgate fully
The maximum roof load is 220 lbs(100 kg).
Attaching the roof carrier X
Secure the roof carrier to roof rails 0043. In
doing so, observe the manufacturer's
installation instructions. Features
