duces bad odors and removes pollutants
from air entering the passenger compart-
ment.
Activating

lected or if the outside temperature has
fallen below 41
°F(5
°C).
The activated charcoal filter should be
switched off when windows fog up on the
inside, or if the passenger compartment
needs to be quickly heated or cooled
down.
Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-
er as soon as the rear window is clear. The
defroster is automatically deactivated af-
ter approximately 6 to 17 minutes of oper-
ation depending on the outside
temperature.

Air conditioner
The air conditioner is operational while the
engine is running and cools the interior air
to the temperature set by the operator.
Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the automatic
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.

again.
The indicator lamp on
theAC

button goes out.
The air conditioner uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
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.!If the rear window defroster switches
off too soon and the indicator lamp
starts blinking, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
!If the air conditioner cannot be turned
on again, this indicates that the air con-
ditioner is losing refrigerant. The com-
pressor has turned itself off.
Have the air conditioner checked at the
nearest authorized Mercedes-Benz
Center.

When closing the panorama sliding/pop-up
roof, ensure that no one is in danger of being
injured.
If the panorama sliding/pop-up roof is
closed with the convenience closing feature
and becomes blocked, it will not open auto-
matically.
Should this occur, press the release button
on the key and hold it down; the panorama
sliding/pop-up roof opens again.
Make sure to remove the key from the igni-
tion lock even when leaving the vehicle for
only a brief period of time.
In the event of an accident, the glass in ve-
hicles with a glass roof may shatter.
If the vehicle rolls over, there is a danger of
occupants without fastened seat belts being
thrown out of the opening.
In this case there is an increased risk of in-
jury even for passengers with fastened seat
belts, as entire body parts or portions of
them may protrude from the passenger
compartment.

It is necessary to resynchronize the pan-
orama sliding/pop-up roof after:
voltage supply interruption due to a

Solar panel*
Combined with the panorama slid-
ing/pop-up roof a solar panel is available.
The solar cells convert natural light into
electrical energy. When the engine is
switched off, the energy generated auto-
matically switches on the ventilation fan.
The constant air flow creates a cooler tem-
perature for cars parked in the sunlight.
The air flow depends on the intensity of the
solar radiation. The ventilation starts 2
minutes after switching off the engine.
