Notes on using the air-conditioning
system
Air-conditioning system
Below, you can find a number of notes and
recommendations to help you use the air-
conditioning system optimally.
RSwitch on cooling with air dehumidification
using the ¿button. The indicator lamp
in the ¿button lights up.
RSet the temperature to 72 ‡ (22 †).
RRecommendation for air distribution in
winter: set theOand¯ settings.
Recommendation for air distribution in
summer: set thePsetting.
ROnly use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
ECO start/stop function
During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require full climate
control capacity, the ECO start/stop function can be deactivated by pressing the ECO but-
ton (
Ypage 145).

Automatic climate control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your automatic climate control.
RActivate climate control using the Ãand
¿ buttons or the Ábutton on the
control panel of the climate control. The
indicator lamps in the Ãand¿ but-
tons or the Ábutton light up.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" func-

again.
ROnly use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
RUse the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp in the ábutton goes out.
RUse the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual

Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.

the rear window defroster switches off auto-
matically after several minutes.
If the battery voltage is too low, the rear win-
dow defroster may switch off.

Switching air-recirculation mode
on/off
General notes
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.
Activating or deactivating
XTurn the SmartKey to position 2in the igni-
tion lock (
Ypage 139).
XTo activate: press thegbutton.
The indicator lamp in the gbutton lights

iAir-recirculation mode is automatically
activated at high levels of pollution (dual-
zone automatic climate control only) or at
high outside temperatures. When air-recir-
culation mode is activated automatically,
the indicator lamp in the gbutton is not
lit. Outside air is added after about
30 minutes.
XTo deactivate: press thegbutton.

Switching the residual heat on or off
General notes
The residual heat function is only available on
vehicles for Canada.
It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutesafter the
engine has been switched off. The heating
time depends on the set interior temperature.
