R Activate climate control using the 0058and
005A buttons. The indicator lamps above
the 0058 and005A buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
R Only 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.
R Use 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 above the 00D6button goes
out.
R Vehicles with COMAND: if you change the
settings of the climate control system, the
climate status display appears for approx-
imately three seconds at the bottom of the
screen in the COMAND display. See also
the separate COMAND operating instruc-
tions. You will see the current settings of
the various climate control functions.

Overview of climate control systemsClimate control

Optimum use of 3-zone automatic cli-
mate control
Climate control system The 3-zone automatic climate control is only
available on vehicles for Canada.
The following contains instructions and rec-
ommendations to enable you to get the most
out of your 3-zone automatic climate control.
R Activate climate control using the 0058and
005A buttons. The indicator lamps above
the 0058 and005A buttons light up.
R In automatic mode, you can also set the
climate mode (FOCUS/MEDIUM/
DIFFUSE). The MEDIUM level is recommen-
ded.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
R Only 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.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above the 00D6 button goes out.
R Use the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual
heat function can only be activated or deac-
tivated with the ignition switched off.
R Vehicles with COMAND: if you change the
settings of the climate control system, the
climate status display appears for approx-
imately three seconds at the bottom of the
screen in the COMAND display. See also

General notes In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
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.

tion mode
General notes You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
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.
