Air inlet
Ensure that the exterior air inlet grille and the chamber
located at the base of the windscreen are kept clean
and free of dead leaves, snow etc.
If you are cleaning the vehicle with a high pressure
washer, avoid targeting anywhere near the air inlet.
Air vents
The face-level vents (except the central vent) have
grilles for orienting the air direction (up-down, right-
left) and thumbwheels for adjusting the air low.
The rear seat positions have air vents with grilles for
orienting the air direction and thumbwheels for ope -
ning and closing the air low.
Air circulation
Optimal comfort is obtained by a good distribution of
air in the front and the rear of the passenger compart -
ment.
To obtain the best use from the air conditioning sys -
tem, take care not to obstruct the air outlets located
under the front seat, in the rear of the vehicle and in
the boot.
Pollen ilter - Odour ilter
Your installation has a special ilter for excluding dust.
This ilter should be changed at the prescribed inter -
vals (see the Maintenance Guide).
Additional heating
Vehicles with HDi engines may be itted with
automatic additional heating for an enhanced
comfort level.
When the engine is idling or the vehicle is sta -
tionary, it is normal to notice a high-pitched his -
sing sound and a slight emission of fumes.
Air conditioning
At any time of year, the air conditioning is useful for
removing air humidity and misting.
To keep the air conditioning compressor well sealed,
it is essential to operate the air conditioning at least
once in every month.
To be effective, the air conditioning should only be
used with the windows closed.
If you are towing a heavy trailer or if outside tempera -
tures are very high, the air conditioning may be tempo -
rarily interrupted in favour of engine cooling.
Water arising from condensation in the air conditioning
is allowed to drain out through an aperture provided for
this purpose ; a pool of water may thus form beneath
the vehicle when stationary.
You are recommended to have the air conditioning
system checked on a regular basis (see Maintenance
Guide).
The air conditioning uses energy from the engine to
operate. This results in extra fuel consumption
Sensor
The automatic regulation of the air conditioning inside
the passenger compartment makes use of the sunlight
sensor located over the dashboard.
Take care not to obstruct it.

The air conditioning can function only when the engine i s running. Press on the button located on the das-
hboard.
To obtain air conditioning, the air blower control 3 should not be in the zero position.
Conditioned air is obtained by a mixing of warm air with ref rigerated air. The “blown air temperature adjust-
ment” control 5 allows you to adjust the conditioned air provided control 4 is operational.
5 - Adjusting the air conditioning temperature
The MAX position simultaneously triggers the air conditioning and th e air recirculation in order to cool the
interior of your vehicle more rapidly.
As soon as the air recirculation is longer necessary it should be swi tched off by pressing button 6 or by
moving away from the MAX position, so as to permit air renewal in the passenger compart ment.
6 - Rear screen demisting
Can operate only when the engine is running.
A press on the control activates the electric demisting of the re ar screen and the rear view mirrors.
Goes out automatically in order to avoid excessive consumption of power.
One press stops the demisting.
Press again to restore operation.
Note: If the engine is stopped before demisting is completed, th e latter will resume as soon as the engine
is started again.

To demist or deice the windows rapidly (because of humidity, n umerous passengers, frost, etc.), select the
visibility programme.
The warning lamp for this programme will come on.

Note:
- When starting from cold, in order to avoid distributing too much cold air, the blower builds up to its normal
speed progressively as the engine warms up.
- An air low of zero will prevent the system from working and will stop the whole of the air conditioning
system.

Manual recalling of one or more functions
Each of the functions
5-7 and 8 can be adjusted ma -
nually.
Then the display of the “AUTO” function disappears.
3 - Adjustment of temperature on left
hand side
4 - Adjustment of temperature on right hand side
To display the temperature you desire, press on but -
ton 3 or 4.
The difference between the temperatures on the right
and on the left cannot be greater than 5.
A long press on the button makes the temperature for
the passenger equal to that programmed by the dri -
ver.
An adjustment around 21 will provide a temperature
that is comfortable.
Depending on your requirements, an adjustment
between 18 and 24 is normal.
Notes:
If you enter the vehicle after a lengthy stop and the
inside temperature is far too cold (or far too hot) than
is comfortable, do not alter the temperature setting to
try and restore the desired comfort level. The system
will automatically and rapidly deploy maximum power
to make up the difference in temperature.
For maximum comfort from one trip to the next, your
adjustments are retained provided the temperature
has altered little; otherwise the air conditioning will re -
sume in automatic mode. 5 - Air conditioning
Press the switch located on the dashboard.
Warning lamp lit up and snowlake on the dis -
play = in operation.
Use the AUTO mode to avoid misting of the windows
in damp or cold weather.
6 - Recirculation of interior air
By pressing the button, the intake of exterior air
is halted and the warning lamp lights.
Without affecting the other adjustments, this po -
sition prevents the entry of unpleasant odours or f umes
from outside. It is recommended that the control sh ould
not be left in the recycling position for longer th an is
necessary for demisting and the renewal of air in t he
passenger compartment.
For this, press the “AUTO” button, or press again on
the air recycling button.
