General notes The pollution filter
The pollution filter (a combined particulate
filter and active carbon filter) serves as a bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system 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 the A/C button to
prevent further damage and have it checked
by a specialised workshop.
● Repairs to the air conditioner require spe-
cialist knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and temperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
● Keep the air intake slots in front of the
windscreen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle interior and is extracted by slots in the
luggage compartment designed for this pur-
pose. Therefore, you should avoid obstruct-
ing these slots with any kind of object.
● The air conditioner operates most effective-
ly with the windows and the sliding/tilting
sunroof* closed. However, if the temperature
inside the vehicle 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 condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour.
● At low outside temperatures, the compres-
sor switches off automatically and cannot be
switched on even with the AUTO button.
● It is advisable to turn on the air condition-
ing at least once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a » 113Technical specifications

Operation
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 conditioning 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 reasons:
● The engine is stationary.
● The fan blower is switched off.
● The outside temperature is lower than ap-
proximately +3 °C (+37 °F).
● The air conditioning system compressor
has been temporarily switched off because of
an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air
conditioning checked by a specialised work-
shop.
Air recirculation Air recirculation mode on
›››
Fig. 129  (a
lamp lights up on the button) prevents strong
odours or contaminated air 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 re-
circulation mode improves heating perform-
ance by heating air from the interior instead
of cold air from the outside.
When the outside temperature is high, air re-
circulation mode improves cooling perform-
ance 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 dis-
tribution control is set to the windscreen set-
ting  . 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 recir-
culation is connected automatically to pre-
vent the entrance of exhaust gases in the ve-
hicle on travelling backwards. The control
lamp on the button  does not light up.
● If the temperature control is turned to the
coldest setting (blue point) and the A/C but- ton is on, the “Air recirculation” function is
automatically activated in order to cool the
vehicle faster using less energy, and its func-
tion control lamp will light up.
● If the function is not deactivated by press-
ing the button, it will deactivate after approx-
imately 20 minutes. 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.

Operation
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 adjust-
ment, except as necessary to suit individual
preferences 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 selected, LO or
HI
ar
e respectively displayed on the screen.
These are approximate temperatures which
may slightly vary depending on the outside
conditions.
Climatronic maintains an excellent, comforta-
ble temperature by automatically adjusting
the supplied air temperature, the blower
speed and the air distribution. The system al-
so considers the sunlight radiation, so there
is no need for manual readjustment. There-
fore, automatic mode alwa
ys 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 air
distribution or blower. The temperature con-
tinues to self-regulate.
To switch off Climatronic, press the –
9 button repeatedly until the display switches
off. Manual mode In manual mode the air temperature, flow,
and the desired air distribution can be adjus-
ted.
Switching on manual mode
– Press one of the buttons ››› Fig. 130 14 to
16 or press the blower control
8 and
9 .
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 depending on the outside
conditions.
If you select temperatures below +18 ℃
(+17.78 ℃), the indication: L O
will appear on
the screen. 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 se-
lected, the screen will show HI
. In this setting
the system runs at maximum heating output
and the temperature is not controlled.
Blower
The blower can be adjusted using buttons
››› Fig. 130 8 and
9 . If the blower is off
(level 1 is not shown on the screen) andbutton
9 is pressed after 1 second, the Cli-
matronic switches off.
Air distribution
The air distribution is adjusted using the but-
tons  ,
 and
 . It is also possible to
open and close some of the air outlets sepa-
rately.
Switching the air conditioning on and off
By pressing the A/C button, the air cooling
system can be switched off in order to save
fuel. The temperature continues to self-regu-
late. The set temperature can then only be
reached if it is higher than the outside tem-
perature.
In rain or high humidity, we recommend
switching the A/C on so that the evaporator
does not allow the windscreen to steam up.
Air recirculation mode –
Press the button  to switch air recircula-
tion mode on or off. This is ON if the sym-
bol  ›››
