Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 26).Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following 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
dehumidification function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof
closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 154).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 99).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly. i
The integrated filter filters out most
particles 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 Booklet.
i It is possible that the residual heat
function may be activated automatically an
hour after the SmartKey is removed. The
vehicle is then ventilated for 30 minutes to
dry the automatic climate control. 144

To reduce the airflow (Y page 152)
O To reduce the temperature (Y page 151)Information about using 3-zone
automatic climate control
Automatic climate control The 3-zone automatic climate control is only
available on vehicles for Canada.
The following contains instructions and
recommendations to enable you to get the
most out of your automatic climate control.
R Activate climate control using the Ãand
¿ buttons. The indicator lamps above
the à and¿ buttons light up.
R In automatic mode, you can also use the
ñ button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM level is recommended.
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
temperature settings on the driver's side
for the front-passenger side and the rear
compartment as well. The indicator lamp
above the ábutton 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 deactivated 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
approximately three seconds at the bottom
of the screen in the COMAND display. See also the separate COMAND operating
instructions. You will see the current
settings of the various climate control
functions.
ECO start/stop function During automatic engine switch-off, the ECO

windows can fog up more quickly. Therefore,
deactivate the cooling with air-
dehumidification function only briefly.
The "Cooling with air dehumidification"
function is only available when the engine is
running. The air inside the vehicle is cooled
