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:
R switch off climate control only briefly
R switch on air-recirculation mode only briefly
R switch on the cooling with air dehumidifica-
tion function
R switch on the defrost windshield function
briefly, if required
The dual-zone automatic climate control regu-
lates the temperature and the humidity in the
vehicle interior and filters undesirable substan-
ces out of the air.
Dual-zone automatic climate control is only
operational when the vehicle is ready to drive.
Optimum operation is only achieved with the
side windows closed.
Always keep the ventilation flaps behind the
side paneling in the cargo compartment clear.
Otherwise the vehicle will not be ventilated cor- rectly. i
Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 76). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i The 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.
i It is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-tilated for 30 minutes. Control panel for dual-zone automatic climate control

Climate control system The following contains instructions and recom-
mendations to enable you to get the most out of
your dual-zone automatic climate control.
R Activate climate control using the 0058and
005A buttons. The indicator lamps in the
0058 and005A buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" function
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 otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
R Use the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side as well. The indicator
lamp in the 00D6button goes out.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display; see separate operating
instructions. You will see the current settings
of the various climate control functions.
You can choose between various drive programs
with the program selector button (Y page 114).
If you have selected drive program E+:
R the cooling output is reduced when cooling
R heat output is reduced when heating
R the time for which the rear window defroster
will run is reduced
If you have selected drive program Eor S, the
current climate settings are maintained. Operating the climate control sys-
