Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.

WARNING
Observe the settings recommended on the
following pages. The windows could other-
wise mis tup. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
THERMATIC/THERMOTRONIC automatic cli-
mate control controls the temperature and
the humidity of the vehicle interior and filters
out undesirable substances from the air.
THERMATIC/THERMOTRONIC automatic cli-
mate control is only operational when the
engine is running 17
.O ptimum operation is
only achieved if you drive with the side win-
dows and sliding sunroof/panorama sliding
sunroof closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 96). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out pollen.
Aclogged 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 it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30 minutes to dry
the air-conditioning system.
17 THERMOTRONIC automatic climate control: the residual heat function can only be activated/deactivated
when the ignition is switched off. 136

matic climate control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your THERMOTRONIC automati ccli-
mate control.
R Activate climate control using the Ãand
¿ buttons .The indicator lamps above
the à and¿ buttons light up. You
can also set the airflow and air distribution
of the automatic climate control to one of
three levels (FOCUS/MEDIUM/DIFFUSE).
You can set the desired level using button
G.T he MEDIUM level is recommended.
R Set the temperature to 22 †.
R Only use the demisting function briefly,
until the windscreen is clear again.
R Only use the air-recirculation mode briefly,
e.g. if there are unpleasant outside odours
or when in a tunnel. The windows could
otherwise mist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above
the á button 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 resid-
ual heat function can only be activated or
deactivated with the ignition switched off. Operating the climate control system
Switching climate control on/off
Important information i
When climate control is switched off, the
air supply and air circulation are also
switched off. Only select this setting briefly. Otherwise, the windows may mist
up.
i Switch on climate control primarily using
the à button (Y page 140).

with air dehumidification function
Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted.
G
WARNING
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident. Operating the climate control system

Condensation may drip from the underside of
the vehicle when THERMOTRONI
Cis in cool-
ing mode. This is normal and not a sign that
there is a malfunction.
i The cooling with air dehumidification
function uses refrigerant R134a. This cool-
ant does not contain chlorofluorocarbons,
and therefore does not damage the ozone
layer.

Problems with the cooling with air
dehumidification function When you press the
¿button, the indica-
tor lamp in the button flashes three times or
remains off. You can no longer switch on the
cooling with air dehumidification function.

mode
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.

tion if cooling with air dehumidification is also
activated. If desired, cooling with air dehu-
midification can be deactivated. X

same for all control panels. G
WARNING
Only switch over to air-recirculation mode
briefly at low outside temperatures. Other-
wise, the windows could mist up, thus impair-
ing visibility and endangering yourself and
others. This may prevent you from observing
the traffic conditions, thereby causing an
accident.

as the side windows are opened and closed.
Make sure that all object sand body parts are
clear of the side windows when they are being
opened or closed .You or the objects could be
drawn in or become trapped between the side
window and the door frame as the window
moves. If there is arisk of entrapment, oper-
ate the Wswitch to move the side window

Activating/deactivating the residual
heat function
The residual heat function is only available
with THERMOTRONIC automatic climate con-
trol.
It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off .The heating
time depends on the temperature that has
been set.
i The blower will run at a low speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30 minutes to dry
the air-conditioning system.
X Turn the key to position 0in the ignition
lock or remove it.

i Residual heat is deactivated automati-
cally:
R after about 30 minutes
R when the ignition is switched on
R if the battery voltage drops
R if the coolant temperature is too low Auxiliary heating
Important safety notes G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels.
The material could otherwise ignite and set
the vehicle alight. Choose your parking spot
accordingly.
Operating the auxiliary heating is thus pro-
hibited at filling stations or when your vehicle
is being refuelled. You must therefore switch
off the auxiliary heating at filling stations.
! 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.
i Switch on the auxiliary heating regularly,
e.g. for about ten minutes every month.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated directly using the
vehicle's fuel. For this reason, the tank con-
tent must be at least at reserve fuel level 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. Operating the climate control system
