Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Center for informa-
tion on the installation of an approved
external antenna. Refer to the radio trans-
mitter operation instructions regarding use
of an external antenna.
iThe steering wheel heating does not
turn off automatically.
Warning!
G
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 serious
personal injury.

Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle. A driver’s
attention to the road must always be
his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call.
If you choose to use the telephone
1 while
driving, please use the hands-free device
and only use the telephone when road,
weather and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
cellular telephone while driving a vehicle.
Only operate the COMAND (Cockpit Man-
agement and Data System) if road, weather
and traffic conditions permit.
1Observe all legal requirements.
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.Warning!

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 before an-
swering or placing a call.
!The initial activation of the Tele Aid sys-
tem may only be performed by com-
pleting the subscriber agreement and
placing an acquaintance call using
the¡button. Failure to complete
either of these steps will result in a sys-
tem that is not activated.
If you have any questions regarding ac-
tivation, please call the Response Cen-
ter at 1-800-756-9018 (in the USA) or

Emergency calls
An emergency call is initiated automatical-
ly following an accident in which the emer-
gency tensioning devices (ETDs) or
air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 274) for instruc-
tions on initiating an emergency call man-
ually.

appears in the multifunction display and
the audio system is muted. When the con-
nection is established, the message
Call connected
appears in the multifunc-
tion display. All information relevant to the
emergency, such as the location of the ve-
hicle (determined by the GPS satellite loca-
tion system), vehicle model, identification
number and color are generated.A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to deter-
mine more precisely the nature of the
emergency provided they can speak to an
occupant of the vehicle.The Tele Aid system is available if
it has been activated and is operation-
al. Activation requires a subscription

Programming or reprogramming the in-
tegrated remote control
Step 1:
Switch on the ignition (

Step 2:
If you have previously programmed an
integrated signal transmitter button
and wish to retain its programming,
proceed to step 3. Otherwise, press
and hold the two outer signal transmit-
ter buttons1 and3 and release
them only when the indicator lamp4
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory. If you later wish to program a
second and/or third hand-held trans-
mitter to the remaining two signal
transmitter buttons, do not repeat this
step and begin directly with step 3.Step 3:
Hold the end of the hand-held remote
control transmitter6 of the device
you wish to train approximately 2 to
5 in (5 to12 cm) away from the surface
of the integrated remote control locat-
ed on the interior rear view mirror,
keeping the indicator lamp4 in view.
Step 4:
Using both hands, simultaneously
press the hand-held transmitter
button5 and the desired integrated
signal transmitter button (1, 2
or3). Do not release the buttons until
completing step 5.
The indicator lamp4 on the integrat-
ed remote control will flash, first slowly
and then rapidly.
