Activating/deactivating cooling with 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 mist 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 cooling mode is active. This is normal
and not a sign that there is a malfunction.
Activating/deactivating X
To switch on: press the¿button.
The indicator lamp above the ¿button lights up.
i In vehicles with auxiliary heating, one of the indicator lamps on the auxiliary heating button lights
up when the "Cooling with air dehumidification" function is activated.
X To switch off: press the¿button.
The indicator lamp above the ¿button goes out. The cooling with air dehumidification function
has a delayed switch-off feature.

X Consult a qualified specialist workshop. Setting climate control to automatic
mode
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.

opened using the convenience opening fea-
ture. Switching the residual heat on/off
General notes 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.
The "residual heat" function only functions opti- mally with the side windows closed.

X To switch off: press theÌbutton.
The indicator lamp above the Ìbutton
goes out.
Residual heat is deactivated 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 dis-
charge location can be found 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. 132
Operating the climate control systemClimate control

i
Switch the auxiliary heating on regularly
once a month for about ten minutes.
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 tank content
must be at least at reserve fuel level 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 automatically after 50 minutes. This time limit can be altered.
To do this, visit a qualified specialist workshop.
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 139).
X Set the desired temperature.
Auxiliary heating or auxiliary ventilation can also
be switched on if the manually set climate con-
trol is activated. Optimum comfort is attained by setting the system to automatic mode. Set the
temperature 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 226). Switching the auxiliary heating/venti-
lation on or off using the button on the
centre console The colours of the indicator lamps in button
:
mean the following:
R blue: auxiliary ventilation is switched on
R red: auxiliary heating is activated
R yellow: departure time is preselected
(Y page 226)
X To switch on the auxiliary heating or aux-
iliary ventilation:
press button:.
The red or blue indicator lamp in button :
lights up.
X To switch off the auxiliary heating or aux-
iliary ventilation: press button:.
The red or blue indicator lamp in button :
goes out.
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 Operating the climate control system
133Climate control Z

R
the remote control being in an unfavourable
position in relation to the vehicle
R transmitting from an enclosed space
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 135).
