Important notesIn chapter “Telephone”, you will find de-
tailed information regarding the telephone,
including emergency call, SMS function
and service numbers.
1 Observe all legal requirements
Please read the chapter “Telephone”
first before attempting to operate your
telephone.

Always drive with extreme caution
when you operate the telephone
hands-free.

For safety reasons, you should not use
the mobile telephone handset to make
a call while driving the vehicle.
If the signal strength is very weak (dis-
play in the top right corner of display):
Wait until reception improves before
making a call.
Warning
G
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle. Whether or not prohibited by law, for
safety reasons, the driver should not use the
cellular telephone while the vehicle is in mo-
tion. Stop the vehicle in a safe location be-
fore answering or placing a call.
If you nonetheless choose to use the cellular
phone while driving, please use the hands-
free device and be sure to pay attention to
the traffic situation at all times. Use the cel-
lular phone
1 only when road, weather and
traffic conditions permit.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e.
without being connected to an external an-
tenna) from inside the vehicle while the en-
gine is running. Doing so could lead to
malfunction of the vehicle’s electronic sys-
tems, possibly resulting in an accident and/
or personal injury.
!Radio transmitters, such as a portable
telephone or a citizens band unit
should only be used inside the vehicle
if they are connected to a separate ex-
terior antenna that has been approved
by Mercedes-Benz.

69 Telephone
Important notes

Close the windows and reduce all out-
side noise as much as possible when
you use hands-free operation.

A brief disconnection from the cellular
network is not a malfunction, as this
can occur when the network switches
areas. The phone will automatically try
to sign on to a network again.

If the message “Locked. Please enter
code” appears, enter the unlock code
to enable all telephone functions
(page 78).

If a menu other than the telephone
menu is displayed on the COMAND
screen, the display will change if an
outgoing call is sent out via the multi-
function steering wheel.In the following situations, it is not possible
or not yet possible to use the telephone:

The telephone is already unlocked but
is not or not yet registered in the net-
work.
The message “No Service” appears.
The telephone will try to register into
an existing network. If the network is
available, the telephone will be ready
for use.
The above message also appears 
if the network is no longer available
due to weak signals

if you try to make a call (message
appears for 8 seconds)

The message “Telephone is being acti-
vated. Please wait.” appears.
COMAND prepares the telephone for
use. Select other system functions, e.g.
radio, by pressing the corresponding
button or wait until the telephone is ac-
tive.

One of the two messages “No telepho-
ne” or “Telephone not plugged in” ap-
pears.
Please connect the telephone.

The message “Telephone defective”
appears.
Please contact an authorized
Mercedes-Benz Center.

sible to use the functions “Dial number
from phone book”, “Redial” and
“Speed-dial”:
The mobile telephone has been
plugged into its holder correctly, the
COMAND operating unit has been swit-
ched on and the phone book download
function has been actuated (see tele-
phone operation guide).
Once the download process has been
completed, the above functions be-
come available. It is not possible to make a call when one
of the following messages appears:

“System busy, redial?”
Dialing has failed because system is
busy.

“No service, redial?”

cannot be received.
