Instructions and recommendations for
optimum air conditioning:
R activate the air conditioning using
the à and¿ buttons. The indica-
tor lamps above the Ãand¿ but-
tons come on. You can also set the air-
flow and air distribution of the automatic
air conditioning to one of three levels
(FOCUS/MEDIUM/DIFFUSE). You can
set the desired level using button G. The
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 out-
side odours or when in a tunnel. Other-
wise, the windows could mist up due to
a lack of fresh air.
R use the "ZONE" function to adopt the
temperature settings on the driver's side for the front-passenger side and the rear
compartment as well. The indicator lamp
above the ábutton goes out.
R use the "residual heat" function if you
want to heat or ventilate the vehicle inte-
rior when the ignition is switched off. The
"residual heat" function can only be acti-
vated or deactivated with the ignition
switched off. Switching the air conditioning on/off
i When the air conditioning is switched off,
the air supply and air circulation are also
switched off. Only select this setting briefly,
otherwise the windows may mist up.

Risk of accident
If you switch off the "Cooling with air dehu-
midification" function, the air inside the vehi-
cle will not be cooled (in warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions and thereby
cause an accident.
Condensation may drip from the underside of
the vehicle when Thermatic is in cooling
mode.
X To activate: press the¿button.
The indicator lamp above the ¿button
comes on.
X To switch off: press the¿button.
The indicator lamp above the ¿button
goes out. The cooling with air dehumidifi-
cation function has a delayed switch-off
feature. Controlling the air conditioning auto-
matically
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.
The automatic air conditioning will achieve
optimal operation if "cooling with air dehu-
midification" is also activated. If necessary,
cooling with air dehumidification can be deac-
tivated.

Risk of injury
Very hot or very cold air can flow from the air
vents. This could cause burns or frostbite to
bare skin in the immediate vicinity of the air
vents. Keep bare skin away from these air
vents. If necessary, direct the airflow to a dif-
ferent area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i For virtually draught-free ventilation,
adjust the sliders of the air vents to the
centre position.

Notes on the auxiliary heating/ventila-
tion system G
Risk of poisoning
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
Risk of fire
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling stations or when your vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
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 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 automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation Air conditioning
