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.

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 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 on
again.

Tele Aid
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 and
informationThe 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 multifunction steering wheel. To
raise, press buttonæ and to lower,
press buttonç. The volume can also be
adjusted using the volume knob on your
audio system or COMAND* head unit.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.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.
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 ten seconds or do not come on). The
message
Tele Aid inoperative appears
in the multifunction display.
!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
1-888-923-8367 (in Canada).
iThe SOS button is located in the overhead
control panel (
page 31).
The Roadside Assistance button• and the
Information button¡ are located in the cen-
ter armrest compartment below the cover
(
page 278).
iThe 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 is unavailable, the
Tele Aid system may not function and if this oc-
curs, assistance must be summoned by other
means.

Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:
Check the frequency of hand-held re-
mote 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 an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.
If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.
Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.
iCertain types of garage door openers are in-
compatible with the integrated remote control. If
you should experience further difficulties with
programming the integrated remote control,
contact an authorized Mercedes-Benz Center, or
call Mercedes-Benz Customer Assistance
Center (in the USA only) at
1-800-FOR-MERCedes, or Customer Service (in
Canada) at 1-800-387-0100.

Battery
Your vehicle’s battery is located in the
engine compartment on the right-hand
side (
page 447).
The battery should always be sufficiently
charged in order to achieve its rated
service life. 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 the battery, always use
batteries approved by Mercedes-Benz.
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.Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
