!The lighter socket can be used to
accommodate 12V DC electrical
accessories (up to a maximum 85 W)
designed for use with the standard
“cigarette lighter” plug type. Keep in
mind, however, that connecting acces-
sories to the lighter socket (for exam-
ple extensive connecting and
disconnecting, or using plugs that do
not fit properly) can damage the lighter
socket. With the socket damaged, the
lighter may no longer be able to be
placed in the heating (pushed-in) posi-
tion, or the lighter may pop out too ear-
ly with the lighter not hot enough.
To help avoid damaging the cigarette
lighter socket, we recommend con-
necting 12V DC electrical accessories
designed for use with a standard “ciga-
rette lighter” plug type to the 12V pow-
er outlets (
page 259) in your vehicle
whenever possible.
iThe power outlet can be used to ac-
commodate 12-V DC electrical acces-
sories (e.g. air pump, auxiliary lamps)
up to a maximum 180 W.

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.
iAn additional power outlet is located on
the left side in the trunk.iTo install or remove the floormat more
easily, move the driver’s seat or front
passenger seat as far to the rear as
possible (
page 40).
Warning!
G
Whenever you are using floormats, make
sure there is enough clearance and that the
floormats are securely fastened.
Floormats should always be securely fas-
tened using eyelets2 and retainer pins1.
Before driving off, check that the floormats
are securely in place and adjust them if nec-
essary. A loose floormat could slip and
hinder proper functioning of the pedals.
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.

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.
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.
1Observe all legal requirements.
!The initial activation of the Tele Aid
system may only be performed by
completing the subscriber agreement
and placing an acquaintance call using

either of these steps will result in a
system that is not activated.
If you have any questions regarding
activation, please call the Response
Center at 1-800-756-9018 (in the USA)

ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the COMAND System or on the multi-
function steering wheel. To raise, turn the
rotary volume control on COMAND System

System self-check
Initially, after switching on ignition, mal-
functions are detected and indicated (the
indicator lamps in the SOS button, the
Roadside Assistance button• and the
Information button¡ stay on longer
than 10 seconds or do not come on). The
message
Malfunction. Drive to work-
shop
appears in the multifunction display.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 264) for
instructions on initiating an emergency call
manually.
Once the emergency call is in progress, the
indicator lamp on the SOS button will
begin to flash. The message
Connecting Call
appears in the multifunc-
tion display. When the connection is estab-
lished, the message
Call connected
appears in the multifunction display. All in-
formation relevant to the emergency, such
as the location of the vehicle (determined
by the GPS satellite location system), vehi-
cle model, identification number and color
are generated.
iWhen a Tele Aid call has been initiated,
the COMAND System audio is muted
and the selected mode (radio, tape or
CD) pauses. The optional cellular
phone (if installed) and inserted in cra-
dle switches off. If you must use this
phone, we recommend that you use it
only with the vehicle at a standstill in a
safe location. Remove the phone from
the cradle and place the call. The navi-
gation* system (if engaged) will contin-
ue to run. The multifunction display in
the instrument cluster is available for
use, and spoken commands are only
available by pressing the RPT button on
the COMAND System. A pop-up win-
dow will appear in the COMAND Sys-
tem display to indicate that a Tele Aid
call is in progress. After the Tele Aid
call has ended, the optional cellular
phone switches on again. A PIN entry
might be necessary.

the Roadside Assistance button, and/or on
the Information button remain illuminated
continuously in red and/or the message Malfunction. Drive to workshop

system has been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.
