Good visibility
Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the
defroster as soon as the rear window is
clear. The defroster is automatically
deactivated after approximately
6 to 17 minutes of operation depending on
the outside temperature.Activating
Press buttonF on the automatic
climate control panel (
page 188).
The indicator lamp on the button
comes on.Deactivating
Press buttonF again.
The indicator lamp on the button goes
out.
Warning!G
Any accumulation of snow and ice should be
removed from the rear window before
driving. Visibility could otherwise be
impaired, endangering you and/or others.
!If the rear window defroster switches off too
soon and the indicator lamp starts flashing, this
means that too many electrical consumers are
operating simultaneously and there is insuffi-
cient voltage in the battery. The system re-
sponds automatically by deactivating the rear
window defroster.
As soon as the battery has sufficient voltage, the
rear window defroster automatically switches
back on automatically.

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
storage compartment (
page 207).
!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, how-
ever, that connecting accessories to the lighter
socket (for example extensive connecting and
disconnecting, or using plugs that do not fit prop-
erly) 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 early with the
lighter not hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC elec-
trical accessories designed for use with a stan-
dard “cigarette lighter” plug type to the
12 V power outlets in your vehicle whenever
possible.
iThe power outlet can be used to accommo-
date 12V DC electrical accessories (e.g. air
pump, auxiliary lamps) up to a maximum
of 180 W or as a battery charging point
(
page 368).
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.

Tele Aid
Shortly after the completion of your Tele
Aid acquaintance call, you will receive a
user ID and password. By visiting
www.mbusa.com and selecting “Tele Aid”
(USA only), you will have access to account
information, remote door unlock, and
more.The Tele Aid system
(Tele
matic Alarm Identification on
D
emand)
The Tele Aid system consists of three
types of response:

Automatic and manual emergency

Roadside Assistance

Information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and
cellular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the audio system or on the multifunc-
tion steering wheel. To raise, turn the rota-
ry volume control on the audio system
clockwise or press buttonæ on the
multifunction steering wheel. To lower,
turn the rotary volume control on the audio
system control counterclockwise or press
buttonç on the multifunction steering
wheel.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
!The initial activation of the Tele Aid system
may only be performed by completing the sub-
scriber agreement and placing an acquaintance
call using the ¡button. Failure to complete
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) or
1-800-387-0100 (in Canada).
iThe SOS button is located above the inside
rear view mirror (
page 217).
The Roadside Assistance button•
(
page 217) and the Information button¡
(
page 218) are located in the center storage
compartment.
!The Tele Aid system utilizes the cellular net-
work for communication and the GPS (
Global Po-
sitioning
System) satellites for vehicle location.
If either of these signals are unavailable, the Tele
Aid system may not function and if this occurs,
assistance must be summoned by other means.
iWhen a Tele Aid call has been initiated, the
audio system is muted and the selected mode
(radio or CD) pauses. The mobile phone (if in-
stalled) switches off. If you must use this phone,
we recommend that you use it only with the ve-
hicle 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 end-
ed, the optional mobile phone switches on again.
A PIN entry might be necessary.

Reprogramming a single signal
transmitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Switch on the ignition (page 40).
Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.
Indicator lamp1 will begin to flash af-
ter 20 seconds. Without releasing the
signal transmitter button, proceed with
programming starting with step 3.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
controlled 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 outer
signal transmitter buttons2 and 4,
for approximately 20 seconds, until
indicator lamp1 flashes rapidly. 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 280-390 MHz.

Put a new battery in hand-held remote
control5. This will increase the likeli-
hood of the hand-held remote control
sending a faster and more accurate sig-
nal to the integrated remote control.

While performing step 3, hold
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying
angles at the distance of 2 to 5 in
(5 to 12 cm) away or the same angle at
varying distances.
iUpon completion of programming the inte-
grated remote control, make sure you retain the
hand-held remote control that came with the ga-
rage door opener, gate operator or other device.
You may need it for use in other vehicles, for fu-
ture programming of an integrated remote con-
trol, or simply for continued use as a hand-held
remote control to operate the respective device
in other situations.
iIf you sell your vehicle, erase the codes of all
three channels.

256 Operation
Trunk
Batteries
Your vehicle is equipped with two
batteries:

Starter battery in the trunk

Consumer battery in the trunk
These batteries should always be suffi-
ciently charged in order to achieve its rat-
ed service life. A flat battery must be fully
recharged. Refer to Maintenance Booklet
for battery maintenance intervals.
If you use your vehicle mostly for
short-distance trips, you will need to have
the battery charge checked more
frequently.
When replacing batteries, always use bat-
teries approved by Mercedes-Benz. Have
this work only carried out by an authorized
Mercedes-Benz Center.
If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized Mercedes-Benz Center about
steps you need to observe.For more information on battery mainte-
nance, see “Batteries” (
page 367).
