General notes G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pull-
ing away.
The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking feature (Y page 98).
It is only possible to shift the transmission
from position Pto the desired position if you
depress the brake pedal. Only then is the
parking lock released. If the brake pedal is not
depressed, the DIRECT SELECT lever can still be moved but the parking lock remains
engaged.
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Information on the automatic release of the
electric parking brake (Y page 222).
Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot from the brake pedal to the accelerator pedal and to depress it before the vehicle begins to
roll. 192

WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if: R you are pulling away on a level road or on a

except plug-in hybrid)
Introduction This section describes the ECO start/stop
function for all vehicles except PLUG-IN
HYBRID vehicles. Information on the ECO
start/stop function in PLUG-IN HYBRID vehi-
cles (Y page 288).
The ECO start/stop function switches the
engine off automatically if the vehicle is stop- ped under certain conditions.
The engine starts automatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
reduce the fuel consumption and emissions
of your vehicle.
Important safety notes G
WARNING
If the engine is switched off automatically and you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving. There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away. General notes

Object detection
The rear view camera can detect moving and
stationary objects. If, for example, a pedes-
trian or another vehicle is detected, these
objects are marked with bars. The system is
only able to detect and mark stationary
objects when your vehicle is moving. When
the vehicle is stationary, moving objects can
be detected and marked.
To ensure that you can use the function, it
must be switched on in COMAND (see the
separate operating instructions). 360° camera (surround view)
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 side cameras in the exterior mirrors
The cameras capture the immediate sur-
roundings of the vehicle. The 360° camera
assists you, for instance when parking or at
exits with reduced visibility.
The 360° camera images can be shown in full screen mode or in seven different split-screenviews 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 image from the front camera
(130° viewing angle 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 images from the rear-facing
side cameras (rear wheel view)
R top view and images from the forward-
facing side cameras (front wheel view)
When the function is active and you shift the
transmission from Dor Rto N, the guide lines
in the COMAND display 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 and may show
a distorted view of obstacles, show them
incorrectly or not at all. The 360°camera is
not a substitute for attentive driving.
You are always responsible for safe maneu-
vering and parking. When maneuvering or
parking, make sure that there are no persons, animals or objects in the area in which you are
maneuvering.
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
R if the trunk lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the cameras are exposed to very bright
light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if the camera lenses fog up, e.g. when driv-
ing into a heated garage in winter, causing
a rapid change in temperature 260
