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 sunlight
the interior temperature is excessive,
air the passenger compartment by
opening the windows for a few mo-
ments, then close them again.
The air conditioning operates by using
power from the engine. This results in
a slight increase in fuel consumption.

Air circulation

front seats provide enhanced heat-
ing for the rear seat positions; take
care not to obstruct them.
Air vents
The air vents to the face 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
a number of sensors (sunlight sen-
sor, outside temperature sensor...)
that relieve you of the need to make
frequent adjustments outside the
displayed temperature.
Be careful not to obstruct the sun-
light sensor, located on the dash-
board behind the instrument panel.

ent types of air distribution.
The air distribution chosen
is shown by the lighting of
the corresponding warning
lamps on the display 2.
3. Mode of adjustment of temperature for
the passenger
Press on button 3 to have inde-
pendent passenger control of
cabin air temperature. The warn-
ing lamp goes out.
While the passenger is adjusting
temperature,the warning lamp lights
up. 4. Air recirculation
This control is for isolating disagree-
able odours or fumes coming from
outside.
Press on button 4 , to exclude
entry of outside air. The warning
lamp lights up.
This should be cancelled as soon as possible to permit renewal of
cabin air and to prevent misting.

AUTOMATIC AIR CONDITIONING
A. DRIVER’S CONTROL PANEL
1. Automatic comfort regulation
A p r e s s o n t h i s b u t t o n , c o n fi r m e d
by the display of the A/C warn-
ing lamp and of AUTO on the
screen, provides automatic
control, at the temperature selected, of
all the following 5 functions:
- a i r fl o w ,
- cabin temperature, on left hand side and right hand side,
- air distribution,
- air conditioning,
- automatic air recirculation. For this facility to operate, it is rec-
ommended to keep all the air vents
open.
Using the
AUTO mode will prevent
misting inside the vehicle in cold or
humid weather.
When starting from cold, in order to
avoid a rush of cold air, the blower
attains its optimum level progres-
sively. 2. Adjustment of temperature
To display the desired temperature,
press button:
-
- to decrease the temperature,
- + to increase the temperature.
An adjustment around 21 will pro-
vide an agreeable temperature level.
However, depending on your prefer-
ence, anything between 18 and 24
is quite normal.
For optimum comfort, it is recom-
mended to avoid an adjustment dif-
ference greater than 3 between right
and left.
Actual temperatures experienced in
the passenger compartment are de-
pendent on external factors and for
this reason might not be identical to
those displayed.
On entering the vehicle, the inside
temperature may be much colder (or
hotter) than would be comfortable. It
serves no purpose to alter the tem-
perature displayed in an attempt to
attain your preference more rapidly.
The system automatically does all in
its power to make up the difference
in temperature as soon as possible.
Manual resumption of one or
more functions
It is possible to adjust each of the
functions 3, 4 , 6 and 10 manually.
The display of the "AUTO" function
will then go off.
Resumption by the driver of the
adjustment of cabin temperatures
(for the front and rear passengers)
A long press on the "AUTO" but-
ton will realign the temperature
for all passengers with the prefer-
ences of the driver.

According to version, the
automatic mode makes use of an
air quality sensor. This analyses the
air and isolates the passenger com-
partment from the exterior as soon
as it detects the presence of pollut-
ants. Then it automatically activates
recirculation of cabin air.
