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 27).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 air humidity in the vehicle interior. The air
filter cleans the air, thus improving the
interior climate.
The "Cooling with air dehumidification"
function is only available when the engine is
running. Optimum climate control 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 163).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature
(Y page 100). This will speed up the cooling process and the desired 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 blower may be
activated automatically 60 minutes after
the key has been removed depending on
various factors, e.g. the outside
temperature. The vehicle is then ventilated
for 30 minutes to dry the automatic climate
control. 152
Overview of climate control systemsClimate control

Notes on using climate control
Automatic climate control Below, you can find a number of notes and
recommendations to help you use climate
control optimally.
R Activate climate control using the 0058
rocker switch. The indicator lamp in the
0058 rocker switch lights 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 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. The residual heat function is switched
off when the ignition is switched on.
If you are controlling the rear climate control
using the front control panel, note the
following:
R If you set rear-compartment climate
control using the front control panel, the
00A4 symbol appears in the rear-
compartment control panel display.
R If the rear-compartment climate control is
set using the front control panel, it cannot
be set at the same time using the rear
control panel. If controlling the rear climate
control from the front control panel is
locked, wait five seconds. You will then be
able to control the rear climate control
using the rear control panel.
R After selecting the rear compartment
settings, the front climate control can be
controlled automatically again via
COMAND after five seconds. Alternatively, you can select "Cancel rear
compartment" in the COMAND air-
conditioning function bar.
ECO start/stop function During automatic engine switch-off, the
climate control only operates at a reduced
capacity. If you require the full climate control
output, you can switch off the ECO start/stop
function by pressing the ECO button
(Y
page 177). Operating the climate control

air dehumidification
General notes If you deactivate the "Cooling with air-
dehumidification" function, the air inside the
vehicle will not be cooled. The air inside the
vehicle will also not be dehumidified. The
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
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
malfunction.
