– Using the controls A
and C and with the switch B ⇒ fig. 99
you can adjust the temperature, the air distribution and the
blower speed.
– Press the button D
to switch air recirculation mode on or off.
When the function is activated, a warning light on the button is
turned on.
Temperature
Switch A
adjusts temperature. The required temperature inside the vehicle
cannot be lower than the ambient temperature. Maximum heat output, which is needed to defrost the windows quickly, is only available when the
engine has reached its operating temperature.
Blower
The air flow can be set at four speeds with switch
B
. The blower should al-
ways be set at the lowest speed when driving slowly.
Air distribution
Control C
for setting the flow of air in the required direction.
 – Air distribution towards the windscreen in order to demist. For safety
reasons, it is not recommended to switch air recirculation on.
 – Air distribution to the upper body
 – Air distribution to footwell
 – Air distribution to the windscreen and the footwell.
Air recirculation mode 
Air recirculation mode D
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 heat-
ing 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 famili-
arise yourself with the correct operation of the heating and ventilation
system, including the demist/defrost functions for the windows.
● In air recirculation mode, no cold air from the outside enters the vehi-
cle interior. The windows can quickly fog over if the heating is switched
off. Therefore, never leave the air recirculation mode switched on for a
long time (risk of accident).

Vehicle interior heating or cooling system
Fig. 103 Air condition-
ing controls on the dash
panel
Interior heating
– Disconnect the cooling system using button ⇒ fig. 103 AC
(the
button light turns off). –
Turn the temperature selector A
to set the desired temperature
inside the vehicle.
– Turn the blower switch to any of the settings 1-4.
– Set the air distribution control C
to the air flow configuration
desired:  (towards the windscreen),  (towards the chest),
 (towards the footwell) and  (towards the windscreen and
footwell areas).
Interior cooling
– Connect the cooling system with button AC
(the button light
should light up).
– Turn the temperature control switch until the desired interior
temperature is reached.
– Turn the blower switch to any of the settings 1-4.
– Set the air distribution control to the air flow configuration de-
sired: 
(towards the windscreen),  (towards the chest), (towards the footwell) and  (towards the windscreen and
footwell areas).
Heating
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 hu-
midity go down. This way, if the outside humidity is extreme, the air condi-
tioning prevents the misting of the windows and therefore, comfort is im-
proved.
If the air conditioning does not work, this may be due to the following rea-
sons: 

137
Air conditioning
● The engine is stationary.
● The fan blower is switched off.
● The outside temperature is below +3 ℃.
● 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. 103 
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. 104 7 is visible.
– Press keys 10
and 11 ⇒ fig. 104 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. 104 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. 104. 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. 
