KEYLESS-GO
General notes
Bear in mind that the engine can be started by
any of the vehicle occupants if there is a
SmartKey in the vehicle.
Locking/unlocking centrally
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the SmartKey with you. You can combine the
functions of KEYLESS-GO with those of a con-
ventional SmartKey. Unlock the vehicle by
using KEYLESS-GO, for instance, and lock it
using the &button on the SmartKey.
The driver's door and the door at which the
handle is used, must both be closed. The
SmartKey must be outside the vehicle. When locking or unlocking with KEYLESS-GO, the
distance between the SmartKey and the cor-
responding door handle must not be greater
than 3 ft (1 m). A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart- Key is in the vehicle. This occurs, for example:
R when starting the engine
R whilst driving
R when the external door handles aretouched
R during convenience closing

surface of the door handle.
X To lock the vehicle: touch sensor sur-

Activating/deactivating cooling with
air dehumidification
General notes
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, only
deactivate the "Cooling with air-dehumidifi-
cation" function briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperatureselected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc- tion.

Rear view camera
General notes
The rear view camera :is an optical parking
and maneuvering aid. It uses guide lines to
show the area behind your vehicle in the
Audio/COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
iThe text shown in the Audio/COMAND
display depends on the language setting.
The following are examples of rear view
camera messages in the Audio/COMAND
display.
Observe the notes on cleaning ( Ypage 279).
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 there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed.
Observe the notes on cleaning(Y page 279)
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).
Activating/deactivating the rear view
camera
X To activate: make sure that the key is in
position 2in the ignition lock.
X Make sure that the
Activation by R
gearfunction is selected in Audio 20/

X Engage reverse gear.
The area behind the vehicle is shown with
guide lines in the Audio 20/COMAND dis-
play.
The image from the rear view camera is
available throughout the maneuvering
process.
To deactivate: the rear view camera deacti-
vates if you shift the transmission to Por after
driving forwards a short distance.
Displays in the Audio 20/COMAND dis-play
The rear view camera may show a distorted
view of obstacles, show them incorrectly or
not at all. The rear view camera does not show

ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h) to
125 mph (200 km/h) range. If ATTEN-
TION ASSIST detects typical indicators of fati-
gue or increasing lapses in concentration on
the part of the driver, it suggests taking a
break.
Important safety notes
ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.
