General notes In automatic mode, the set temperature is
maintained automatically at a constant level. The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi- cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly. Setting climate control to automatic X

The support provided by the system can be
impaired if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
R the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R there are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are strong shadows cast on the road
The system is switched to passive and no lon-
ger assists you by performing steering inter-
ventions if:
R you actively change lane
R you switch on the turn signal
R take your hands off the steering wheel or do
not steer for a prolonged period of time
i Steering Assist and Stop&Go Pilot are
activated again automatically after a lane
change is completed.
Steering Assist and Stop&Go Pilot do not pro- vide any support:
R on very sharp corners
R when a loss of tire pressure or a defective
tire has been detected and displayed
Pay attention also to the important safety
notes for DISTRONIC PLUS (Y page 178).
The steering interventions are carried out
with a limited steering moment. The system requires the driver to keep his hands on the
steering wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel sym-
bol appears in the multifunction display. If you have still not started to steer and have not
taken hold of the steering wheel after five
seconds at the latest, a warning tone also
sounds to remind you to take control of the
vehicle. Steering Assist and Stop&Go Pilot are
switched to passive. DISTRONIC PLUS

ROAD SURFACE SCAN i
This function is not available in all coun-
tries. The ROAD SURFACE SCAN function monitors
the road in front of the vehicle using multi-
function camera 0043at the top of the wind-
shield. This function is automatically active if you select comfort suspension tuning. The
system is operational at speeds of up to
81 mph (130 km/h).
This function allows bumps in the road sur-
face to be detected before the vehicle drives
over them. The spring struts are then actu-
ated, with the result that chassis movements
are significantly reduced when driving over
bumps.
The system is deactivated when you select
the raised vehicle level, sports mode or the
dynamic cornering function.
The system may be impaired or may not func-
tion if:
R the road surface is insufficiently lit
R there is poor visibility, e.g. snow, rain, fog or
spray
R there is glare, e.g. from the sun or from
oncoming traffic
R the windshield is dirty, fogged up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
R the road surface has no texture or is reflec-
tive, e.g. in the case of newly laid asphalt,
concrete slabs or puddles
R the distance to the vehicle in front is too
short
R sections of the route have a very small
radius of curvature
R you accelerate hard or brake sharply AIRMATIC
General notes AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-
round level control ensures the best possible suspension and constant ground clearance,
even with a laden vehicle. When you drive

General notes Rear view camera
0043is under a flap in the
trunk lid.
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. Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
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 camera is 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 lens fogs up, e.g. when driving
into a heated garage in winter, causing a
rapid change in temperature
R if the camera lens is dirty or obstructed.
Observe the notes on cleaning
(Y page 330)
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
rear view camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. license plate holder, bicycle rack).
The guide lines in the COMAND display show
the distances to your vehicle. The distances
only apply to road level.
i The rear view camera is protected from
raindrops and dust by means of a flap.
When the rear view camera is activated,
this flap opens.
The flap closes again when:
R you have finished the maneuvering proc-
ess
R you switch off the engine
R you open the trunk
Observe the notes on cleaning
(Y page 330).
For technical reasons, the flap may remain
open briefly after the rear view camera has been deactivated. Driving systems

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 six 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 six 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 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 Driving systems
