Air recirculation mode

Air recirculation mode on (a lamp lights up in red) prevents strong odours
from the outside air from entering in the vehicle, for example when passing
through a tunnel or in a traffic jam ⇒.
When the outside temperature is low, air recirculation mode improves
heating performance by heating air from the interior instead of cold air from
the outside.
WARNING
•For your safety, the windows should never be fogged up or covered with
snow or ice. This is essential to ensure good visibility. Please familiarise
yourself with the correct operation of the heating and ventilation system,
including the demist/defrost functions for the windows.

Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Coolant system
When the air conditioning is switched on, the temperature and the air
humidity go down. This way, if the outside humidity is extreme, the air condi-
tioning prevents the misting of the windows and therefore, comfort is
improved.
If the air conditioning does not work, this may be due to the following
reasons:•The engine is stationary.•The fan blower is switched off.•The outside temperature is below +3°C.•The cooling system compressor has been temporarily switched off
because of an increased engine coolant temperature.•The air conditioning fuse is faulty.•Another fault in the vehicle. Have the air conditioning checked by a qual-
ified workshop.
Air recirculation
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside.When air recirculation mode is switched on (button ⇒page 119, fig. 90
with warning lamp) strong odours in the outside air do not enter the vehicle
interior, for example when passing through a tunnel or in a traffic jam.
When the outside temperature is low, air recirculation mode improves
heating performance by heating air from the interior instead of cold air from
the outside.
When the outside temperature is high, air recirculation mode improves
cooling performance by cooling air from the interior instead of warm air from
outside.
For safety reasons, it is not recommended to switch air recirculation on when
the air distribution control is being adjusted to the windscreen setting
.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).
Note
•When engaging reverse gear, the air recirculation is connected automati-
cally to prevent the entrance of exhaust fumes in the vehicle on travelling
backwards. The control light on the button does not light up.•If the temperature control is turned to the coldest setting (blue point) and
the switch is activated, the “Air recirculation” function is automatically
activated in order to cool the vehicle rapidly using less energy; its function
indicator will light.

•If the function is not deactivated by pressing the button, this will deacti-
vate after approx. 20 min.Economic use of the air conditioningWhen the air conditioning is switched on, the compressor consumes engine
power and has influence on fuel consumption. Consider the following points
in order to have the system operating in the minimum possible time.
•If the vehicle interior has overheated due to an excessive solar radiation,
it is best to open the windows or doors to allow the hot air to escape.•While in motion, the air conditioning should not be switched on if the
windows or the sunroof are open.*

(72°F) is set in automatic mode. Therefore, we recommend you not to change
this adjustment, except as necessary to suit individual preferences or partic-
ular circumstances. The passenger compartment temperature can be set
between +18°C (64°F) and +29°C (86°F). If a lower or higher temperature is

imate temperatures which may slightly
vary depending on the outside condi-
tions.
Climatronic maintains a constant temperature. To do it, it automatically regu-
lates the supplied air temperature, the blower speed and the air distribution.
The system also considers the sunlight radiation, so there is no need for
manual readjustment. Therefore, automatic mode almost always provides
the best comfort for the vehicle occupants throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, blower or . The temperature continues to
self-regulate.
Manual mode
In manual mode the air temperature, flow, and the desired air
distribution can be adjusted.Switching on manual mode
– Press one of the buttons ⇒page 121, fig. 91 to or press
the blower control and down. The indicator is switched off
.Te m p e r a t u r e
The passenger compartment temperature can be set between +18°C (64°F)
and +29°C (86°F). These are approximate temperatures which may slightly
vary depending on the outside conditions.
If a temperature below 18°C (64°F) is selected, the display switches to LO In
this setting the system runs at maximum cooling output and the temperature
is not regulated. If a temperature above 29°C (86°F) is selected, the display switches to
HI In
this setting the system runs at maximum heating output and the temperature
is not controlled.

heating performance by heating air from the interior instead of cold air from
the outside.
When the outside temperature is high, air recirculation mode improves
cooling performance by cooling air from the interior instead of warm air from

For safety reasons, it is not recommended to switch air recirculation on when
the air distribution control is being adjusted to the windscreen setting
.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).
Note
When engaging reverse gear, the air reci rculation is connected automatically
to prevent the entrance of exhaust fumes in the vehicle on travelling back-
wards. In this case the symbol for air recirculation is not displayed.General notesThe impurity filter
The impurity filter (a combined particle filter and active carbon filter) serves
as a barrier against impurities in the ambient air, including dust and pollen.
For the air conditioning system to work with maximum efficiency, the pollen
filter must be replaced at the specified intervals in the Maintenance Program. If the filter loses efficiency prematurely due to use in areas reaching very high
pollution levels, the pollen filter must be changed more frequently than
stated in the Service Schedule.
Caution
•If you suspect that the air conditioning is damaged, switch it off with
button to prevent further damage and have it checked by a qualified
workshop.•Repairs to the air conditioning system require specialist knowledge and
special tools. Therefore, we recommend you to take the vehicle to a qualified
workshop.Note
•If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a puddle
underneath the vehicle. This is completely normal and there is no need to
suspect a leak.•Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over.•The air from the vents flows through the vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects.•The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the vehicle has been over-
heated by sun, the air inside can be cooled quicklier by opening the windows
for a short time.•Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.•At low outside temperatures the compressor switches off automatically.
The button cannot be switched on either.
