The indicator lamp on the button
comes on.
Warning!
G
When the outside temperature is
below 41°F (5°C), only switch to air
recirculation mode for short periods to
prevent window fogging.
Window fogging may impair visibility and
endanger you and others.
iIf you keep button, pressed, the
side windows and tilt/sliding sunroof*
will close.Warning
G
Never operate the side windows and the
tilt/sliding sunroof* if there is the possibility
of anyone being harmed by the closing
procedure.
In the event that the procedure causes po-
tential danger, the closing of the side win-
dows can be immediately halted by
releasing the, button or by pressing or
pulling the respective window switch. The
closing of the tilt/sliding sunroof* can be
immediately halted by releasing the,
button or by moving the tilt/sliding sunroof*
switch in the overhead control panel in any
direction.
iThe air recirculation mode is activated
automatically:

at high outside temperatures


if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases, for example in a
tunnel (charcoal filter must be
activated for the air recirculation
mode to be activated automatically)
The indicator lamp on the, button
is not lit when the air recirculation
mode is automatically switched on.
After approx. 30 minutes, outside air is
added to the air inside the vehicle.
If you have turned off the air
conditioning (
page 204) or the out-
side temperature is below 41°F (5°C),
the air recirculation mode will not
switch on automatically.

The air recirculation mode is deactivated
automatically:


after five minutes if the outside
temperature is below
approximately 41°F (5 °C)


after five minutes if the air conditioning
is turned off


after 30 minutes if the outside
temperature is above
approximately 41°F (5 °C)At outside temperatures above 79°F
(26 °C) the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.
Charcoal filter
An activated charcoal filter markedly
reduces bad odors and removes pollutants
from air entering the passenger compart-
ment. The charcoal filter can be activated
or deactivated.
The system switches automatically to the
air recirculation mode, if the

carbon monoxide (CO)
or


nitrogen oxide (NO
X)
concentration of the outside air increases
beyond a predetermined level.
iIf you keep button, pressed, the
side windows and tilt/sliding sunroof*
will return to their previous position.

The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.Deactivating

tioning (cooling) function of the automatic
climate control system. The air in the

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.Warning!

If you turn off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog
up more quickly. Window fogging may

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 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 ten seconds or do not come on).
!The initial activation of the Tele Aid
system may only be performed by
completing the subscriber 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 above the
interior rear view mirror.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest
cover.
iThe Tele Aid system utilizes the cellular
network for communication and the
GPS (G
lobal P
ositioning S
ystem) satel-
lites for vehicle location. If either of
these signals is unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.
