AIR CONDITIONING
This system automatically adjusts the temperature, the
flow of air and the distribution of air inside the cabin,
depending on your desired comfort level.
Provided you retain automatic mode (by pressing button
« AUTO ») and all the air vents are open, you will main-
tain an optimum comfort level, also removing humidity
and misting, whatever the ambient climatic conditions.
The temperature inside the cabin cannot be lower than
the temperature outside if the air conditioning is not
operating.
To be effective, the air conditioning should only be used
with the windows closed. If after a lengthy stop in bright
sunlight the interior temperature is excessive, air the
passenger compartment by opening the windows for a
few moments, then close them again.
To keep the air conditioning compressor well sealed, it
is essential to operate the air conditioning at least once
in every month.
The air conditioning operates by using power from the
engine. This results in a slight increase in fuel consump-
tion.
Sensors
The automatic regulation of the air conditioning inside
the cabin uses a number of sensors (sunlight, ambient
temperature, inside temperature, etc.) relieving you of
the need to make your own adjustments within a normal
temperature range.
The humidity sensor is there to prevent misting inside
the vehicle.
Be careful not to obstruct the sensors A and C.

Air inlet
Check that the exterior grille for the air inlet, at the bot-
tom of the windscreen, is clean and free of dead leaves,
snow, etc..
If washing the vehicle with a high pressure jet, avoid
targeting the air inlet zone.
Air circulation
For your comfort we advise you to maintain a proper
distribution of air within the cabin, both at the front and
at the rear.
The air vents to the face have thumbwheels so that you
can adjust the flow of air, and grilles to orient the direc-
tion.
There are air vents on the floor underneath the front
seats and on the rear control panel, for enhanced heat-
ing of the rear seat positions.
Do not obstruct the air outlets located in the boot area.
Dust/pollen filter
There is a filter for excluding pollen and dust.
This filter has to be changed according to the vehicle
maintenance schedule. See « Maintenance Guide ».
Additional heating
Vehicles with an HDi engine may be provided with auto-
matic additional heating for enhanced comfort.
It is normal to notice slight odours or smoke emissions,
especially when the vehicle is idling or stationary.
