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

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.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.

Power outlet
The power outlet is located on the left side
in the trunk.
1Power outlet
Switch on the ignition (
page 40).

Flip up cover and insert electrical plug
(cigar lighter type).
Telephone
The telephone is located in the center stor-
age compartment (
page 201).
!The lighter socket can accommodate
12V DC electrical accessories (up to a
maximum of 85 W) designed for use
with the standard “cigarette lighter”
plug type. Keep in mind, however, that
connecting accessories to the lighter
socket (for example extensive connect-
ing and disconnecting, or using plugs
that do not fit properly) can damage the
lighter socket. With the socket dam-
aged, the lighter may no longer be able
to be placed in the heating (pushed-in)
position, or the lighter may pop out too
early 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 12 V pow-
er outlets in your vehicle whenever
possible.
iThe power outlet can be used to ac-
commodate 12V DC electrical acces-
sories (e.g. air pump, auxiliary lamps)
up to a maximum of 180 W or as a bat-
tery charging point (
page 358).
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 personal
injury.

204 Controls in detailUseful featuresRadio 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.You can take and place telephone calls us-
ing the í and ì buttons on the
steering wheel. To carry out other tele-
phone functions, use the control system
(
page 139).
See separate instruction manual for in-
structions on how to operate the tele-
phone.

System self-check
Initially, after switching on the ignition,
malfunctions 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
Tele Aid – Drive to workshop

appears for approximately 10 seconds in
the multifunction display.Emergency calls
An emergency call is initiated
automatically following an accident in
which the emergency tensioning devices
(ETDs) or airbags have deployed.
An emergency call can also be initiated
manually by opening the cover next to the
inside rear view mirror labeled SOS, then
briefly pressing the button located under
the cover.
For more information, see “Initiating an
emergency call manually” (
page 211).
iWhen a Tele Aid call has been initiated,
the audio system is muted and the se-
lected mode (radio or CD) pauses. The
cellular phone (if installed) switches
off. If you must use this phone, we rec-
ommend 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 multifunction display
in the instrument cluster is available for
use. After the Tele Aid call has ended,
the optional cellular phone switches on
again. A PIN entry might be necessary.
Warning!

If the indicator lamps in the SOS button, in
the Roadside Assistance button, and/or in
the Information button do not come on dur-
ing the system self-check, or if any of these
indicators remain illuminated continuously
in red and/or the message
Tele Aid -
Drive to workshop
is displayed in the
multifunction display after the system
self-check, a malfunction in the system has
been detected.
If a malfunction is indicated as outlined
above, the system may not operate as ex-
pected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.

Step 9:
Press the “training” button on the ga-
rage door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the follow-
ing step.
Step 10:

Return to the vehicle and firmly press,
hold for 2 seconds and release the pro-
grammed signal transmitter button
(2, 3 or4).
Step 11:

Press, hold for 2 seconds and release
same signal transmitter button a sec-
ond time to complete the training pro-
cess.Step 12:

Confirm the garage door operation by
pressing the programmed signal trans-
mitter button (2, 3 or4).
Step 13:

To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the
integrated signal transmitter to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
If you live in Canada or if you are having
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4
with the following:
Step 4:

Press and hold the signal transmitter
button (2, 3 or4). Do not release
this button until it has been successful-
ly trained.
iSome garage door openers (or other
rolling code equipped devices) may
require you to press, hold for 2 seconds
and release the same signal transmit-
ter button a third time to complete the
training process.

Operation of integrated remote control
Switch on the ignition (
page 40).

Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote con-
trolled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.Erasing the integrated remote control
memory

Switch on the ignition (
page 40).

Simultaneously press and hold down
the outer signal transmitter buttons2
and 4, for approximately 20 seconds,
until the indicator lamp1 flashes rap-
idly. Do not hold for longer than
30 seconds.
The codes of all three channels are
erased.Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:


Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 288-399 MHz.


Put a new battery in the hand-held re-
mote control5. This will increase the
likelihood of the hand-held remote con-
trol sending a faster and more accurate
signal to the integrated remote control.


While performing step 3, hold the
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.
iIf you sell your vehicle, erase the codes
of all three channels.
