2006 MERCEDES-BENZ E WAGON warning

205 Controls in detail
Dual-zone automatic climate control (USA only)
The climate control is operational whenev-
er the engine is running. You can operate
the climate control system in either the au-
tomatic or manual mode. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent outside temperature.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 A/C mode is deactivated
(
page 212).
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burns or frostbite to unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance be-
tween unprotected parts of the body and the
air vents. If necessary, use the air distribu-
tion control (
page 204) to direct the air to
air vents in the vehicle interior that are not
in the immediate area of unprotected skin.
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.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval.
A clogged filter will reduce the air vol-
ume to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off, see
“Summer opening feature”
(page 234). The climate control will
then adjust the interior temperature to
the set value much faster.
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.

210 Controls in detailDual-zone automatic climate control (USA only)Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before a driving
through a tunnel). This setting cuts off the
intake of outside air and recirculates the
air in the passenger compartment.Activating

Briefly press button,
(page 204).
The indicator lamp on the button
comes on.
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 212) is activated, or

.
iThe air recirculation mode is activated
automatically at high outside tempera-
tures.
The indicator lamp on button, is
not lit when the air recirculation mode
is automatically switched on.
A quantity of outside air is added after
approximately 30 minutes.
If you have turned off the air condition-
ing (
page 212) or the outside
temperature is below 41°F (5°C), the
air recirculation mode will not switch
on automatically.
Warning!
G
Never operate the windows and tilt/sliding
sunroof* if there is the possibility of anyone
being harmed by the opening or closing pro-
cedure.
In case the procedure causes potential dan-
ger:
The closing of the side windows can be im-
mediately halted by pressing or pulling the
respective window switch. The closing of the
tilt/sliding sunroof can be immediately halt-
ed by moving the switch for the tilt/sliding
sunroof in any direction.
The closing of the side windows and the
tilt/sliding sunroof can be reversed by again
pressing and holding the, button.

212 Controls in detailDual-zone automatic climate control (USA only)Air conditioning
The cooling function, only operational
when the engine is running, cools the vehi-
cle interior down to the selected tempera-
ture. The cooling function also
dehumidifies the air in the vehicle interior,
thus preventing the windows from fogging
up.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.

again.
The indicator lamp on the button

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!
G
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
impair visibility and endanger you and
others.
!If the air conditioning cannot be turned
on again, this indicates that the air con-
ditioning is losing refrigerant. The com-
pressor has turned itself off.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.

218 Controls in detail4-zone automatic climate control*
The climate control is a 4-zone intelligent
climate control system. Your vehicle interi-
or is divided into 4 zones.With the help of a sun sensor, the climate
control determines the relation of the sun
to the vehicle and automatically adjusts
the inside temperature for every individual
zone.
You can set the temperature for each of
the 4 zones separately.
The climate control is operational whenev-
er the engine is running. It cools the vehi-
cle’s interior according to the angle and
intensity of the sun’s rays, the outside tem-
perature and the selected temperature.
You can operate the climate control sys-
tem in either the automatic or manual
mode.
Warning!

When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very

This may cause burn or frostbite to unpro-

vents. Always keep sufficient distance be-
tween unprotected parts of the body and the
air vents. If necessary, use the air distribu-
tion controls (

to air vents in the vehicle interior that are
not in the immediate area of unprotected
skin.
