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 exces-
sive, air the passenger compartment
by opening the windows 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.

Warranty Guide").
Air circulation
A i r v e n t s o n t h e fl o o r u n d e r n e a t h t h e
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
a n d t h u m b w h e e l s t o a d j u s t t h e a i r fl o w
and direction (up-down, right-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.

AUTOMATIC AIR CONDITIONING
A. DRIVER’S CONTROL PANEL
1. Automatic comfort regulation
A press on this button, con-
fi r m e d b y t h e d i s p l a y o f t h e
A/C warning lamp and of
AUTO on the screen, pro-
vides automatic control, at the tem-
perature 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
the formation of mist 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 uses its
maximum performance 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 cancels all personal settings,
including the passenger's tem-
perature, and
returns
the system
to automatic operation.
