Maximum cooling MAXCOOL (USA only)
If U is selected on both the left and
right side and there is a high demand for
cooling, the display “MAXCOOL” appears
in the COMAND display.
This provides the fastest possible cooling
of the vehicle interior (when windows and
tilt/sliding sunroof or tilt/sliding panel*
are closed).
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving in a
tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.
Activating: Press button,
(
page 469) up or down.
The indicator lamp on the button
comes on.
Deactivating: Press button,
(
page 469) up or down.
The indicator lamp on the button goes
out.
Warning!G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.
iIf the rear window defroster switches off too
soon and the indicator lamp goes out, this indi-
cates that too many electrical consumers are op-
erating simultaneously and the load on the
battery is reducing available voltage. The system
responds automatically by deactivating the rear
window defroster.
iMaximum cooling MAXCOOL is only avail-
able when the engine is running.
Warning!G
Fogged windows impair visibility, endanger-
ing you and others. If the windows begin to
fog on the inside, switching off the air
recirculation mode immediately should clear
interior window fogging. If interior window
fogging persists, make sure the air
conditioning (
page 254) is activated, or
press button;.
iThe air recirculation mode is activated auto-
matically at high outside temperatures.
The indicator lamp on button, is not lit when
the air recirculation mode is automatically acti-
vated.
A quantity of outside air is added when the cool-
ing demand is not at maximum.
If the air conditioning has been turned off
(
page 254) or the outside temperature is be-
low 41°F (5°C), the air recirculation mode will
not switch on automatically.

Residual engine heat and ventilation
With the engine switched off, it is possible
to continue to heat or ventilate the interior.
This feature makes use of the residual heat
produced by the engine.
iA window or tilt/sliding sunroof will only re-
turn to its previous position if it has not been
moved to another position using the respective
window switch or tilt/sliding sunroof switch af-
ter it was closed with button,.
A window or tilt/sliding sunroof that has been
moved will remain in its current position if
button, is used to reopen the remaining
windows or tilt/sliding sunroof.
iIf you switch on the residual heat function
when outside temperatures are high, only the
ventilation will be switched on.

ered by the Mercedes-Benz Limited Warranty.
iWhen the panorama roof with power
tilt/sliding panel is open, resonance noises may
result in addition to the usual wind noises. They
are caused by minimal pressure changes in the

Useful features
All information relevant to the emergency,
such as the location of the vehicle (deter-
mined by the GPS satellite location sys-
tem), vehicle model, identification number
and color are generated.
A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to deter-
mine more precisely the nature of the acci-
dent provided they can speak to an
occupant of the vehicle.The Tele Aid system is available if

it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection,
and cellular air time

the relevant monitoring service and
GPS coverage are available and pass
the information on to the Response
Center

there is sufficient voltage in the vehicle
batteries
iDuring the emergency call message “Emer-
gency Call Activated” is displayed, operation
from COMAND is not possible. The automatic cli-
mate control can be still adjusted using the
switches on the climate control panel.
iIf no vehicle occupant responds, an ambu-
lance will be sent to the vehicle immediately.
iLocation of the vehicle on a map is only pos-
sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.
Warning!G
If the indicator lamp in the SOS button is
flashing continuously and there was no
voice connection to the Response Center
established, then the Tele Aid system could
not initiate an emergency call (e.g. the rele-
vant mobile phone network is not available).
The message:

“Call failed” appears in the multifunction
display for approximately 10 seconds.

A pop-up window with the message:
“Call could not be connected! Please dial
911 directly using the mobile telephone
keypad.” appears in the COMAND dis-
play. Confirm the message pressing
n
(
page 88).
Should this occur, assistance must be sum-
moned by other means.
iDuring the emergency call the mobile phone
is switched off automatically and must be
switched back on to make a call.
iThe roof cargo container* may impair mo-
bile phone reception. In an emergency, remove
the mobile phone from the mobile phone cradle
(
page 507) to make a call.
iThe “911” emergency call system is a public
service. Using it without due cause is a criminal
offense.
