Air conditioning
● 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 be-
cause of an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioning checked by a
qualified workshop.
Air recirculation
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside.
When air recirculation mode is switched on (button ⇒ fig. 95
with warn-
ing 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 heat-
ing performance by heating air from the interior instead of cold air from the
outside.
When the outside temperature is high, air recirculation mode improves cool-
ing performance by cooling air from the interior instead of warm air from
outside.
For safety reasons, the air recirculation should not be switched on when the
air distribution control is set to the windscreen setting .
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioner 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 automat-
ically to prevent the entrance of exhaust fumes in the vehicle on travelling
backwards. The warning lamp on the button
does not light up.
● If the temperature control is turned to the coldest setting (blue point)
and the switch AC
is activated, the “Air recirculation” function is automati-
cally 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 conditioning
When 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.

Air conditioning
Automatic mode
In automatic mode air temperature, air flow and distribution
are automatically regulated so that a specified temperature
is attained as quickly as possible, and then maintained. Switching on automatic mode
– Press the button AUTO
. The indication
⇒ fig. 96 7 is visible.
– Press keys 10
and 11 ⇒ fig. 96 to adjust the desired tempera-
ture inside the vehicle. We recommend 22 °C (72 °F).
A comfortable interior climate is quickly reached when a temperature of
+22 °C (72 °F) is set in automatic mode. Therefore, we recommend you not
to change this adjustment, except as necessary to suit individual preferen-
ces or particular circumstances. It is possible to select interior temperatures
from +18 °C (64 °F) to +29 °C (86 °F). If a lower or higher temperature is se-
lected, LO or HI are respectively displayed on the screen. These are approxi-
mate temperatures which may slightly vary depending on the outside condi-
tions.
Climatronic maintains a constant temperature. To do it, it automatically reg-
ulates the supplied air temperature, the blower speed and the air distribu-
tion. The system also considers the sunlight radiation, so there is no need
for manual readjustment. Therefore, automatic mode almost always pro-
vides 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 AC
. 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 ⇒ fig. 96 14
to 16 or press the blower
control 8 and 9 down. The indicator is switched off 3.
Temperature
It is possible to select interior temperatures from +18 °C (64 °F) to +29 °C
(86 °F). These are approximate temperatures which may slightly vary de-
pending on the outside conditions.
If a temperature below 18 °C (64 °F) is selected, the screen will show LO. In
this setting the system runs at maximum cooling output and the tempera-
ture is not regulated.
If a temperature above 29 °C (86 °F) is selected, the screen will show HI. In
this setting the system runs at maximum heating output and the tempera-
ture is not controlled.
Blower
The blower can be adjusted with buttons 8
and 9 ⇒ fig. 96. If the blower
is off (level 1 is not shown on the screen) and button 9 is kept pressed
down, the Climatronic switches off. Then OFF is displayed on the screen.
Air distribution
The air distribution is adjusted using the buttons
, and . It is also
possible to open and close some of the air outlets separately.
Switching the air conditioning on and off
Pressing the button AC
the air cooling system can be switched off in order
to save fuel. The temperature continues to self-regulate. The set tempera-
ture can then only be reached if it is higher than the outside temperature.

Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside.
– Press the button
to switch air recirculation mode on or off.
This is ON if the symbol ⇒ fig. 96 is displayed on the screen.
Air recirculation mode prevents strong odours in the ambient air from enter-
ing 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 heat-
ing performance by heating air from the interior instead of cold air from the
outside.
When the outside temperature is high, air recirculation mode improves cool-
ing performance by cooling air from the interior instead of warm air from
outside.
For safety reasons, the air recirculation should not be switched on when the
air distribution control is set to the windscreen setting .
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioner 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 automatical-
ly 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 notes
Pollution filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the specified intervals in the Maintenance Programme.
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 conditioner is damaged, switch it off with but-
ton AC
to prevent further damage and have it checked by a specialised
workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a specialised
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 pud-
dle 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.

135
Air conditioning
● The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the temperature inside the vehi-
cle is excessive because of the sun, the air inside can be cooled faster 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 AUTO
button cannot be switched on either.
● It is advisable to connect the air conditioning at least once a month, to
lubricate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.
● To ensure correct operation, the grilles on both sides of the screen must
not be obstructed
● When the engine is under extreme strain, switch off the compressor for a
moment.
