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 (

concentration of carbon monoxide (CO) and ni-
trogen oxide in the outside air increases, for ex-
ample in a tunnel.

A quantity of outside air is added after approxi-
mately 30 minutes.

and unpleasant odors in the outside air.
The pollutant-sensitive air-recirculation
mode automatically switches off the
supply of outside air when pollutants are
detected in the air.
i
A 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

41°F (5°C).

203 Controls in detail
4-zone automatic climate control
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.

Press button2 (
page 192) or
(
page 193).
The indicator lamp on the button goes
out.
Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.

Press button2 (
page 192) or
(
page 193) again.
The indicator lamp on the button
comes on.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.Residual heat and ventilation
(Canada only)
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.
i
Condensation may drip out from underneath
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 conditioning is
losing refrigerant. The compressor has turned it-
self off.
Have the air conditioning checked at the nearest
authorized Mercedes-Benz Center.
i
If you switch on the residual heat function
when temperatures are high, only the ventilation
will be switched on.
i
Regardless of the selected air volume, the
blower operates at low speed.

The door windows are equipped with the
express-close and automatic reversal func-
tion. If the window encounters an obstruc-
tion that blocks its path in a circumstance
where you pulled the switch past the resis-
tance point and released it to close the win-
dow, the automatic reversal function will
stop the window and open it slightly.
If the window encounters an obstruction
that blocks its path in a circumstance where
you are closing the window by pulling and
