Air conditioning
We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following functions:
air fl ow, temperature in the passenger
compartment and air distribution, by
means of various sensors (ambient
temperature, sunshine). This elimi-
nates any need for you to change your
settings other than the temperature
value displayed.

 Take care not to cover the sun-
shine sensor A .
If you select the automatic mode (by
pressing the "AUTO" control) and leave
all of the vents open, optimum comfort
will be maintained and humidity and
condensation will be removed regard-
less of the exterior climatic conditions.
The temperature in the passenger
compartment can only be lower than
the ambient temperature if the air
conditioning is on.
HEATING, VENTILATION AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air condi-
tioning must be used with the windows
closed. If the vehicle has been parked
in the sun for a long period and the
interior temperature is very high, fi rst
ventilate the passenger compartment
with the windows open for a few min-
utes, then close the windows.
To keep the air conditioning system
in good working order it is essential
that it is operated at least once a
month.
The air conditioning uses engine power
during its operation. As a result, the fuel
consumption of the vehicle increases.
In certain cases of particularly ardu-
ous use (e.g. towing the maximum
load on a steep gradient in high
temperatures), switching off the air
conditioning saves engine power
and improves the towing capacity.
Air inlet
Check that the exterior grille for the
air inlet, at the bottom of the wind-
screen, is clean and free of dead
leaves, snow, etc.
When washing the vehicle using a
high pressure nozzle, avoid spraying
at the air inlet. Air circulation
Maximum comfort is obtained by
means of a good distribution of air in
the passenger compartment, both in
the front and in the rear.
To obtain a uniform distribution of
air, take care not to block the ex-
terior air intake grille located at the
base of the windscreen, the vents,
the air outlets under the front seats
and the air extractor located behind
the fl aps in the boot.
The front and rear vents are fi tted
with thumbwheels to adjust the air
fl ow and direction. We recommend
that you leave all of the vents open.
Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter must be changed in line
with the vehicle's servicing schedule
(see: "Maintenance and Warranty
Guide").

level of comfort cho-
sen, pressing this con-
trol, confi rmed by the
switching on of indicator lamp A , per-
mits automatic and simultaneous con-
trol of all of the following functions:

Turn control
2 to change
the temperature:
- Clockwise to in- crease the tempera-
ture.
- Anticlockwise to reduce the tem- perature.
The setting required is displayed.
The value indicated on the display
corresponds to a level of comfort
and not to a temperature in degrees
Celsius or Fahrenheit, depending on
the screen confi guration.
A setting around the value 21 usually
provides optimum comfort. However,
depending on your requirements, a
setting between 18 and 24 is normal.
On entering the vehicle, the interior
temperature may be much colder (or
warmer) than is comfortable. There
is no need to change the tempera-
ture displayed to obtain rapidly the
level of comfort required.
The automatic regulation of the air
conditioning will use its maximum
performance settings to correct the
temperature difference as quickly as
possible.
The air conditioning system ope-
rates with the engine running.

Mono-zone: this is the overall regu-
lation of the temperature, distribution
and fl ow of air in the passenger com-
