VENTILATION

A. Sunshine sensor.

B. Air diffusion grille.
The air diffusion grille located in the centre of the dashboard pro-
vides optimum distribution of the
air for the front seats.
This system eliminates unpleas- ant air currents while maintain-
ing an optimum temperature in
the passenger compartment.
To open the air diffusion grille, turn the dial upwards.
To close the air diffusion grille, turn the dial fully downwards.
In very hot weather, to obtain more satisfactory central and side
ventilation, it is advisable to close
the diffused air conditioning.

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

 Please do not block the sunshine
sensor A .
If you select the automatic mode
(by pressing the "AUTO" control)
and leave all of the vents open, opti-
mum comfort will be maintained and
humidity and condensation will be
removed regardless of the exterior
climatic conditions.
The temperature in the passenger
compartment cannot be lower than
the exterior temperature if the air
conditioning is not on.
VENTILATION, HEATING AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air con-
ditioning must be used with the win-
dows closed. If the vehicle has been
parked in the sun for a long period
and the interior temperature is very
high, ventilate the passenger com-
partment with the windows open for
a few minutes, then close the win-
dows.
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 the en-
gine 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 tem-
peratures), switching off the air condi-
tioning permits the recovery of engine
power and therefore increases the
towing capacity.
Air inlet
Check that the exterior grille for the air
inlet, at the bottom of the windscreen,
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 has to be changed in ac-
cordance with the vehicle mainte-
nance schedule (see: "Maintenance
and Warranty Guide").

8. Intake of exterior air/
Recirculation of interior air
This function enables you to isolate
the passenger compartment from
exterior fumes and odours. - When starting with the engine
cold, the fl ow will reach its op-
timum level gradually to pre-
vent an excessive distribution
of cold air.
- When entering the vehicle af- ter it has been parked for a
fairly long period, if the inte-
rior temperature is very diffe-
rent from your comfort setting
there is no need to change
the temperature displayed
in order to quickly reach the
level of comfort required. The
system automatically uses its
maximum performance to cor-
rect the difference in tempera-
ture as quickly as possible.
- The water resulting from the air conditioning condensation
is discharged via an open-
ing provided for this purpose;
therefore, a puddle of water
may form underneath the ve-
hicle when stationary.
- In all seasons, if the weather is cool, the air conditioning
is useful as it removes the
humidity from the air and the
condensation. Avoid driving
for prolonged periods with the
air conditioning switched off.
However, demisting resumes when
the engine is switched on again.
Switch off the rear screen and exte-
rior mirrors demisting when you con-
sider this necessary as low current
consumption reduces fuel consump-
tion.

compartment from exte-
rior fumes and odours.

Intake of air in automatic
anti-pollution mode
This is activated by de-
fault in automatic comfort
regulation mode.
The automatic mode has an air qual-
ity sensor. It analyses the air and
isolates the passenger compart-
ment from the outside if it detects
the presence of pollutants. In this
case, it automatically activates the
recirculation of the passenger com-
partment air.
This function does not detect un-
pleasant odours and therefore does
not prevent them from entering the
passenger compartment. It is not
active when the exterior tempera-
ture is below +5 °C to avoid the risk
of condensation forming inside the
vehicle.
