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.

T h i s fi l t e r h a s t o b e c h a n g e d i n a c -
cordance with the vehicle mainte-
nance schedule (see "Maintenance
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.
F o r o p t i m u m o p e r a t i n g e f fi c i e n c y ,
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 o w a n d d i r e c t i o n ( u p - d o w n , r i g h t -
left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunlight sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

Distribution from the air blower can
be altered at will by placing the dis-
tribution control 1 in an intermediate
position. 2 - Air recirculation
3 - H e a t e r b l o w e r c o n t r o l
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
0 (position 1 minimum ).
4 - Temperature control
The heating/ventilation and manual
air conditioning systems can only
function with the engine running. This position is for excluding
disagreeable odours or emis-
sions 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 misting and to al-
low fresh air into the cabin.
To deactivate air recirculation, press
again on control 2 , the warning lamp
goes out. 5 - Rear screen demisting
Can only be operated with the en-
gine running.
One press on control 5 acti-
vates the electric demisting
of the rear screen and, ac-
cording to version, the exte-
rior rear view mirrors. The warning
lamp comes on.
It switches off automatically to avoid
excessive power consumption.
One press stops the demisting.
A further press starts it again.
If the engine is stopped before the
end of demisting, the operation will
resume the next time the engine is
started.
6 - Air conditioning
The air conditioning will only operate
when the engine is running.
Press on control 6 The warn-
ing lamp comes on.
For air conditioning, the air
blower control 3 must not be
on position "0" .
Air conditioning is obtained by mix-
ing the warm air with refrigerated air.
The temperature control 4 adjusts
the air conditioning provided the
control 6 is operational.

AUTOMATIC AIR CONDITIONING 1 - Automatic operation
This system automatically regulates
t e m p e r a t u r e , a i r fl o w a n d a i r d i s t r i b u -
tion in the passenger compartment
according to the temperature select-
ed (for each side, right and left).
It provides an optimum level of com-
fort regardless of the climatic con-
ditions, by permanent use of the
automatic air conditioning mode
(press the AUTO button ) and with
a l l t h e v e n t s o p e n .

temperature on left
h a n d s i d e
To set and display the de-
sired temperature, rotate
control 2 or 3 :
The display HI (high) cor-
responds to a demand for
maximum heating (above 27).
The display LO (low) cor-
responds to a demand for
maximum air conditioning
(below 15).
3 - Adjustment of
t e m p e r a t u r e o n r i g h t
h a n d s i d e
- To the left to lower the tempera- ture
- To the right to raise the tempera- ture
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,
c o n fi r m e d b y t h e d i s p l a y o f
"A/C" and "AUTO" , auto-
matically manages all the
5 following functions according to
the temperature 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 a comfortable temperature.
There is no point in modifying
the displayed temperature to
try to attain the desired level of
comfort. The system operates
automatically to compensate this
temperature discrepancy as rap-
idly 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.
