Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The cooling with air dehumidification function is
only available when the engine is running. Opti-
mum climate control is only achieved with the
side windows closed.
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 72). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book-
let.
iIt is possible that the blower may be activa-
ted automatically 60 minutes after the engine
has been switched off depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the climate control system.

function cannot be acti-
vated via the multimedia system any longer
(

Setting climate control to automatic
General notes
In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
The "Cooling with air dehumidification" function
is activated automatically in automatic mode.

switch lights up.
XTo switch to manual operation: press the
H rocker switch up or down.
or
XPress the upper or lower section of the _
rocker switch.
In automatic mode, if you adjust the airflow or
air distribution manually, the indicator lamp
above the Ãrocker switch goes out. The
function which has not been changed manually,
however, continues to be controlled automati-
cally. When the manually set function switches
back to automatic mode, the indicator lamp
above the Ãrocker switch lights up again.
Setting the temperature
Different temperatures can be set for the driv-
er's and front-passenger sides.
XSelect key position 2with the Start/Stop but-
ton (Ypage 103).
XTo increase or reduce: press thew
rocker switch up or down.

Defrosting the windshield
General notes
You can use this function to defrost the wind-
shield or to clear a fogged up windshield or front
side windows on the inside.
Switch off the "Windshield defrosting" function
as soon as the windshield is clear again.
Switching on/off
XSelect key position 2with the Start/Stop but-
ton (Ypage 103).
XTo switch on: press the¬rocker switch

switch lights up. The current climate control
settings are deactivated.
The climate control system switches to the
following functions:
Rhigh airflow
Rhigh temperature
Rair distribution to the windshield and front
side windows
Rair-recirculation mode off
iIf necessary, the "Cooling with air dehumid-
ification" function is activated. In this case,
the indicator lamp above the ¿rocker
switch remains switched off.
XTo switch off: press the¬rocker switch
up or down.
The indicator lamp above the ¬rocker
switch goes out. The previously selected set-
tings are restored. Air-recirculation mode
remains deactivated.

XActivate the windshield wipers.
XSwitch on automatic mode using the Ã

iIf you clean the windows regularly, they do
not fog up so quickly.
Rear window defroster
General notes
The rear window defroster has a high current
draw. You should therefore switch it off as soon
as the rear window is clear. Otherwise, the rear
window defroster switches off automatically
after several minutes.
If the battery voltage is too low, the rear window defroster may switch off.

Navigation mode
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating the navigation system.
General notes
Among other things, correct functioning of the
navigation system depends on GPS reception. In
certain situations, GPS reception may be
impaired, there may be interference or there
may be no reception at all, e.g. in tunnels or
parking garages.
The following descriptions apply to navigation
with COMAND. Further information can be
found in the Digital Operator's Manual.
