Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.i
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before its
scheduled interval. A clogged filter will reduce
the air volume to the interior.
If the vehicle interior is hot, ventilate the interior
before driving off, see “Summer opening fea-
ture” (page 239). The automatic climate con-
trol will then adjust the interior temperature to
the set value much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.
Warning!
G
When the automatic climate control system
is switched off, the outside air supply and
circulation are also switched off. Only
choose this settings for a short time. Other-

cle down to the selected interior tempera-
ture. The cooling function also
dehumidifies the air in the vehicle interior,
thereby preventing the windows from fog-
ging up.

only return to its previous position if it has not
been moved to another position using the re-
spective window switch or tilt/sliding sunroof*
switch after it was closed with button:.

Condensation may drip out from underneath
the vehicle. This is normal and not an indication
of a malfunction.Warning!

If you turn off the cooling function, the
interior air is not dried. The windows can fog
up more quickly. Window fogging may
impair visibility and endanger you and

The Tele Aid system utilizes the cellular
network for communication and the GPS (G
lobal
P
ositioning S
ystem) satellites for vehicle loca-
tion. 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.
i
When a Tele Aid call has been initiated, the
COMAND system audio is muted and the select-
ed mode (radio, CD etc.) pauses. The optional
cellular phone (if installed) inserted in cradle
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 naviga-
tion* system (if engaged) will continue to run.
The display in the instrument cluster is available
for use, and spoken commands are only avail-
able by pressing the RPT button on the COMAND
