Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 24). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise 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/
THERMOTRONIC automatic climate control
regulates the temperature and the humidity
of the vehicle interior and filters undesirable
substances from the air.
The air-conditioning system/
THERMOTRONIC automatic climate control
can only be operated when the engine is run-
ning. Optimum operation is only achieved
with the side windows and panorama sliding
sunroof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 147).
Always keep the ventilation flaps behind the
side panelling clear (Y page 128). Otherwise
the vehicle will not be ventilated correctly. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 95). This
will speed up the cooling process and the
desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. With THERMOTRONIC auto- matic 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 Booklet. As this depends on envi-
ronmental conditions, e.g. heavy air pollu-
tion, the interval may be shorter than statedin the Service Booklet.
i Vehicles with auxiliary heating:
under
certain environmental conditions, the
residual heat function may be activated
automatically an hour after the key has
been removed in order to dry the automatic climate control. When the automatic cli-
mate control drying function is active, the
blue LED lamp is lit in the rocker switch in
the centre console. The vehicle is then ven-
tilated for 30 minutes.
Vehicles without auxiliary heating:
under certain environmental conditions,
the residual heat function may be activated automatically an hour after the key has
been removed in order to dry the automatic
climate control. The vehicle is then ventila-
ted for 30 minutes. 136

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 out-
let are situated in front of the right-hand front
wheel.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
Switch the auxiliary heating on regularly once
a month for about ten minutes.
The auxiliary heating timer function calcu-
lates the switch-on time according to the out-
side temperature so that the vehicle is pre-
heated by the departure time. When the
departure time is reached, the auxiliary heat- ing continues to heat for a further five
minutes and then switches off.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature. This
occurs without using the heat of the running
engine. The auxiliary heating is operated
directly using the vehicle's fuel. For this rea-
son, the fuel tank must be at least Õfull to
ensure that the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux- iliary heating could switch from ventilation
mode to heating mode or from heating mode to ventilation mode. 148
Operating the climate control systemClimate control

The auxiliary heating switches off when the
engine is switched off. The auxiliary ventila-
tion switches off when you turn the key to key
position 2(Y page 157).
The auxiliary heating switches off automati-
cally 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 157).
X Set the desired temperature.
Auxiliary heating or 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/ventilation can be acti- vated or deactivated using the remote control or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 252).

lation on or off using the button on the
centre console General notes The colours of the indicator lamps on but-

R Blue: auxiliary ventilation activated
R Red: auxiliary heating activated
R Yellow: departure time preselected

Switching the auxiliary heating/venti-

Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For more information, please
contact a qualified specialist workshop.
Store the remote control for the auxiliary
heating so that the auxiliary heating cannot
be switched on unintentionally. In particular,
ensure that the remote control for the auxili-
ary heating is kept out of the reach of chil-
dren.
The remote control has a range of approx-
imately 300 metres. This range is reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
If the remote control battery is low, the bat-
tery symbol on the left of the display is shown as empty. Replace the remote control battery Operating the climate control system
