Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. Otherwise, the windows could
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R activate the "Cooling with air dehumidifica-
tion" function
R activate the "Windscreen demisting" function
briefly, if required
The air-conditioning system or THERMOTRONIC automatic climate control regulates the temper-ature and the humidity of the vehicle interior andfilters undesirable substances from the air.
The air-conditioning system or THERMOTRONIC automatic climate control can only be operatedwhen the engine is running. Optimum operation
is only achieved with the side windows and pan- orama sliding sunroof closed.
The "Residual heat" function can only be
switched on or off if the ignition is switched off
(Y page 137).
Always keep the ventilation flaps behind the
side panelling clear (Y page 122). Otherwise the
vehicle will not be ventilated correctly.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 98). 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. With THERMOTRONIC automatic
climate control, gaseous pollutants and
odours will also be reduced. 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 Service Book-
let. As this depends on environmental condi-
tions, e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet.
i Vehicles with auxiliary heating:
Under
certain environmental conditions, the resid-
ual heat function may be activated automati-
cally an hour after the ignition key has been
removed in order to dry the automatic climate control. The blue LED on the rocker switch in
the centre console lights up when the active
function to dry the automatic climate control is on. The vehicle is then ventilated for
30 minutes.
Vehicles without auxiliary heating: Under
certain environmental conditions, the resid-
ual heat function may be activated automati-
cally an hour after the ignition key has been
removed in order to dry the automatic climate control. The vehicle is then ventilated for
30 minutes. 128
Overview of climate control systemsClimate control

i
If you open the side windows or the pano-
rama sliding sunroof manually after closing
with the convenience closing feature, they
will remain in this position when opened using
the convenience opening feature. Switching the residual heat on/off
General notes The residual heat function is only available with
THERMOTRONIC automatic climate control.
It is possible to make use of the residual heat of the engine to continue heating the vehicle for
approximately 30 minutes after the engine has
been switched off. The heating time depends on
the set interior temperature.
i The blower will run at a low speed regardless
of the airflow setting.
i If you switch on the "Residual heat" function
at high temperatures, only the ventilation will
be activated. The blower runs at medium
speed.
i You cannot use the ventilation to cool the
vehicle interior to a temperature lower than
the outside temperature.
Activating/deactivating X
Turn the key to position gin the ignition lock
or remove it (Y page 144).
X Press the Ìbutton.
The indicator lamp in the Ìbutton lights
up or goes out.
The indicator lamp in the button indicates that the respective function is activated.
i Residual heat is switched off automatically:
R after approximately 30 minutes
R when the ignition is switched on
R if the battery voltage drops
R when the auxiliary heating is switched on Auxiliary heating
Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
The auxiliary heating and the exhaust gas outlet are situated in front of the right-hand front
wheel.
! Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle a maximum of
two times, drive for a longer distance. Operating the climate control systems
137Climate control Z

Switch the auxiliary heating on regularly – once
a month – for about ten minutes.
The auxiliary heating timer function calculates
the switch-on time according to the outside
temperature so that the vehicle is preheated by the departure time. When the departure time is
reached, the auxiliary heating continues to heat for a further five minutes and then switches off.
The auxiliary heating heats the air in the vehicle interior to the set temperature. This occurs with-out using the heat of the running engine. The
auxiliary heating is operated directly using the
vehicle's fuel. For this reason, the fuel tank must
be at least Õfull to ensure that the auxiliary
heating functions.
The auxiliary heating/ventilation automatically
adjusts to changes in temperature and weather conditions. For this reason, the auxiliary heating
could switch from ventilation mode to heating
mode or from heating mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventilation
switches off when you turn the key to key posi-
tion 2(Ypage 144).
The auxiliary heating switches off automatically
after 50 minutes.
You cannot use the auxiliary ventilation to cool
the vehicle interior to a temperature lower than
the outside temperature.
Before switching on X
Turn the key to position 2in the ignition lock
(Y page 144).
X Set the desired temperature.
Auxiliary heating or ventilation can also be
switched on if the manually set climate control is
activated. Optimum comfort is attained by set-
ting the system to automatic mode. Set the tem-
perature to 22 †.
The auxiliary heating or auxiliary ventilation can be switched on/off using the button on the
centre console or the remote control.
The on-board computer can be used to specify
up to three departure times, one of which may
be preselected (Y page 230). Switching the auxiliary heating/venti-
lation on or off using the button on the
centre console General notes
The colours of the indicator lamps on button
:
signify the following:
R Blue: auxiliary ventilation activated
R Red: auxiliary heating activated
R Yellow: departure time preselected

Activating/deactivating the auxiliary
heating or auxiliary ventilation
X Press button :.
The red or blue indicator lamp in button :

Switching the auxiliary heating/venti-
lation on or off using the remote control General notes
Your vehicle comes with one remote control.
You may use two additional remote controls for
your vehicle. For more information, please con-
tact a qualified specialist workshop.
Store the remote control for the auxiliary heat-
ing so that the auxiliary heating cannot be
switched on unintentionally. In particular,
ensure that the remote control for the auxiliary
heating is kept out of the reach of children.
The remote control has a range of approximately
300 metre s. Thisrange is reduced by:
R sources of radio interference
R solid objects between the remote control and
the vehicle 138

If the remote control battery is low, the battery
symbol on the left of the display is shown as
empty. Replace the remote control battery and
observe the important safety notes when doing so (Y page 140).
