Safety Precautions
Safety Precautions
G Warning
Some jurisdictions prohibit the driver from
using a cellular telephone while driving.
Whether or not prohibited by law, for safety
reasons, the driver should not use the cellu-
lar telephone while the vehicle is in motion.
Stop the vehicle in a safe location before
placing or answering a call.
If you nonetheless choose to use the mobile
phone while driving, please use the hands-
free feature and be sure to pay attention to
the traffic situation at all times. Use the mo-
bile phone only when road, weather and traf-
fic conditions permit. Otherwise, you may
not be able to observe traffic conditions and
could endanger yourself and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
G Warning
You and others may damag e y o u r h e a l t h d u e
to excessive electromagnetic radiation. By
using an external antenna, the possible
health risks of electromagnetic fields, which
are under discussion among the scientific
community, should be largely prevented.
G Warning
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.

interface is available in conjunction with a
Bluetooth-enabled mobile phone.
With a suitable mobile phone, you can use
COMAND’s hands-free feature and receive
electronic business cards (vCards) via the

Further information on suitable mobile
phones and connecting Bluetooth-enabled
mobile phones to COMAND is available via

if

there is inadequate GSM network cov-
erage in certain regions

you are switching from one GSM trans-
mitting/receiving station (GSM cell) to
another and there is no voice channel
available in this cell

you are using a SIM card that is not
compatible with the available network.

when using a mobile phone with “Twin-

neously logged into the network with
the second SIM card.

® interface, you
can operate the phone using the following
devices:

COMAND controller and keypad on the
COMAND control unit

Prerequisites for the mobile phone
For making calls using COMAND via the
Bluetooth
® interface, you will need a Blue-
tooth-enabled mobile phone.
i Not all mobile phones available on the mar-
ket are comparably suitable. Further information
on suitable mobile phones and connecting Blue-
tooth-enabled mobile phones to COMAND is
available via the Internet at www.mbusa.com.
Activating Bluetooth®
Before you begin activation of your mobile
phone connection via the Bluetooth® inter-
face please ensure it is compatible with
Bluetooth
® handsfree profile 1.0
(
mobile phone operating guide)
Switch on the mobile phone and enter
the PIN, if applicable (
mobile phone
operating guide).
Activate Bluetooth® connection on the
mobile phone (
mobile phone operat-
ing guide).
i On certain mobile phones, not only do you
have to activate the Bluetooth® function but the
device must also be made “visible” for other de-
vices.
Each Bluetooth
® device has a Bluetooth® device
name. It is recommended to give the device a
personal name, by which you can clearly recog-
nize your mobile phone.
i If the Bluetooth function on the
COMAND is switched off, the message “Blue-
tooth not activated in system settings.” appears.
Activate Bluetooth® connection on
COMAND (
page 169).
Registering a mobile phone
(authorizing)
When you use your mobile phone in con-
junction with COMAND for the first time,
you must register (authorize) it.
It is possible to register several mobile
phones. The connection is always estab-
lished to the mobile phone that was acti-
vated last. When you authorize a new
mobile phone, it is activated automatically.
You can switch between the authorized
mobile phones (
page 88).Searching for a mobile phone
In the phone submenu select “Phone”
K “Phone List” K “Update”.
COMAND searches for suitable Blue-
tooth
® phones within range and enters
them in the phone list.
i The duration of the search procedure de-
pends on the number and type of Bluetooth®
phones. The search may take a few minutes.
When first entering the device list and be-
fore running an update, the black
dotRindicates the active phone (found
and authorized).
After running an update:
Phone icons 3 indicate if a phone is found
(black) or not (grey).

authorized previously, the phone symbol
and the check mark are grey 2.
i If the device list already contains ten autho-
rized devices, you must de-authorize one of the
authorized devices (

pears.
i The passcode is any number chosen by you
between one and sixteen digits in length. We rec-
ommend to use at least four digits because this
improves the quality of the encryption during
connection. The passcode can differ during each
authorization for each device. You must enter
the same number on COMAND and on the device
to be authorized. Please also refer to the instruc-
tions in the mobile phone operating guide.
To enter from COMAND: Select the
digits in the menu bar one after the oth-
er.

® connection is established
successfully, you will be prompted to enter
a code on the mobile phone (

phone as you did on COMAND.
The device is authorized. You can now
make calls via COMAND’s hands-free
device using the authorized
mobile phone.
External authorization
If COMAND cannot find your mobile phone,
this may be due to special security settings
on your mobile phone. In this case, you can
check whether, conversely, your mobile
phone can find COMAND.
