Air conditioning
To ensure that your system operates
correctly, it is recommended to have
it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If after a lengthy stop in bright sun-
light the interior temperature is ex-
cessive, ventilate the passenger
compartment by opening the win-
dows for a few moments, then close
them again.
The air conditioning operates by using
power from the engine. This results in
a slight increase in fuel consumption.
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 servicing
schedule (see "Maintenance and
Warranty Guide").
Air circulation
Maximum comfort is obtained when
there is a good distribution of air in
the passenger compartment, both in
the front and in the rear.
For optimum operating effi ciency,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents have grilles
and thumbwheels to adjust the air fl ow
and direction (up-down, right-left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunshine sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

3 - Heater blower control
The air blower operates only when
the engine is running. For optimum
comfort in the passenger compart-
ment, the control should not remain
in position

This position is for exclud-
ing disagreeable odours
or emissions coming from
outside the cabin. With a
press on control 2 , the entry of air
from outside is closed off, the lamp
comes on.
This should be cancelled as soon
as possible to prevent condensation
from forming and to allow fresh air
into the cabin.
To deactivate air recirculation, press

DIGITAL AIR CONDITIONING 1 - Automatic operation
This system automatically regulates
temperature, air fl ow and air distribu-
tion in the passenger compartment
according to the temperature selected
(for each side, right and left).
It provides an optimum level of comfort
regardless of the ambient conditions,

by permanent use of the automatic
air conditioning mode (press the AUTO
button ) and with all the vents open .
Having no airfl ow prevents the air
conditioning and the system in gen-
eral from working.

To prevent the formation of con-
densation inside the vehicle in
cold and damp conditions, the use
of AUTO mode is recommended. 2 - Adjustment of
temperature on left
hand side
To set and display the de-
sired temperature, rotate
control 2 or 3 :
The display "HI" (high) corre-
sponds to a demand for maxi-
mum heating (above 27).
The display "LO" (low) cor-
responds to a demand for
maximum air conditioning
(below 15).
3 - Adjustment of
temperature on right
hand side
- To the left to lower the temperature
-
To the right to raise the temperature
The difference between the tem-
peratures on the right and on the left
cannot be greater than 3 degrees.
A setting around 21 will provide a
temperature that is comfortable.
Depending on your requirements,
an adjustment between 18 and 24 is
normal.
A press on this control, con-
fi rmed by the display of
"A/C"
and "AUTO" , automatically
manages all the 5 following
functions according to the tempera-
ture chosen:
- Flow of air.
- Cabin temperature.
- Distribution of air.
- Air conditioning.
- Recycling of air.
To enable the system to operate, all
the air vents should be kept open. This is the normal operating
mode.

 When you enter the vehicle, the
temperature inside the vehicle
may be much colder (or warmer)
than is comfortable. There is no
point in modifying the displayed
temperature to try to attain the
desired level of comfort. The
system operates automatically
to correct this temperature differ-
ence as rapidly as possible.

 When starting the engine from
cold, in order to avoid distributing
too much cold air, the blower will
attain its optimum level gradually.

functions
Each of the functions 4 , 6 and 7 can
be adjusted manually.

The temporary lighting of dipped
headlamps after the vehicle’s igni-
tion has been switched off makes
the driver’s exit easier when the light
is poor.
