General notes The 360° camera is a system consisting of
four cameras.
The system analyzes images from the
following cameras:
R Rear view camera
R Front camera
R Two cameras in the exterior rear view
mirrors
The cameras capture the immediate
surroundings of the vehicle. The system
supports 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-screen
view 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 pictures from the rearward
facing mirror cameras (rear wheel view)
R top view and pictures from the forward
facing 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
display. 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
immediate surroundings. You are always
responsible 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
surroundings when parking and
maneuvering. This applies to the areas
behind, in front of and beside the vehicle. You Driving systems

is always emitted when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 7 mph (12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.

of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp :flashes. If
the turn signal remains on, vehicles detected
are indicated by the flashing of red warning
lamp :. There are no further warning tones.

In very rare cases, the system may make an
inappropriate brake application. A course-
correcting brake application may be
interrupted at any time if you steer slightly in
the opposite direction or accelerate.
The course-correcting brake application is
available in the speed range between
20 mph (30 km/h) and 120 mph (200 km/h).
Either no braking application, or a course-
correcting brake application adapted to the
driving situation occurs if:
R there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your
vehicle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds. R

4MATIC (permanent four-wheel drive) If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
! A function or performance test should
only be carried out on a two-axle
dynamometer. Before you operate the
vehicle on such a dynamometer, please
consult a qualified workshop. You could otherwise damage the drive train or the
brake system.
4MATIC ensures that all four wheels are
permanently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to
insufficient grip.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
Further information about "Driving off-road"
(Y page 197).
DSR (Downhill Speed Regulation) Important safety notes
DSR assists you when driving downhill. It
keeps the speed of travel at the speed set on
the on-board computer. The steeper the
downhill gradient, the greater the DSR
braking effect on the vehicle. When driving on
flat stretches of road or on an uphill gradient,
the DSR braking effect is minimal or
nonexistent.
DSR controls the set speed when it is active
and the automatic transmission is in the D,
R or Nposition. By accelerating or braking,
you can always drive at a higher or a lower
speed than that set on the on-board
computer.
Further information about "Driving off-road"
(Y page 197).
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor
override the laws of physics. DSR cannot take
account of road, weather and traffic
conditions. DSR is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
You are always responsible for keeping
control of the vehicle and for assessing
whether the downhill gradient can be
managed. DSR may not always be able to
keep to the set speed, depending on road 256
