Climate control


after five minutes if the air conditioner
is turned off


after 30 minutes if the outside temper-
ature 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.
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.
Activating
Press buttonF.
The indicator lamp on the button
comes on.
Deactivating

Press buttonF again.
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.!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.

iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at speed
setting1 regardless of the air distribu-
tion control setting.

176 Controls in detailAutomatic climate control*Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the economy mode AC
OFF
is se-
lected (
page 174).
Setting the temperature
Use temperature control3 for the left side
or5 for the right side to separately adjust
the air temperature on each side of the
passenger compartment. You should raise
or lower the temperature setting in small
increments, preferably starting at 72°F
(22°C).Increasing

Push top of temperature control rocker
switch3 and/or5.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
Decreasing

Push bottom of temperature control
rocker switch3 and/or5.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
Heating:
Only in manual air distribution mode is it
possible to lower the temperature in the
headroom by adding outside air using
thumbweel7 (
page 172) in the dash-
board.
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.
iIf the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.

Automatic climate control*
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.
Press buttonAC

Moist air can fog up the windows. You can
dehumidify the air with the air conditioner.

PressAC

again.
The indicator lamp on
theAC
OFF
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.
