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.
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's servic-
ing schedule (see "Maintenance and
Warranty Guide").
Air circulation
Air vents on the fl oor underneath the
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 ow
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 rmed by the display of the

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:
- air fl ow,
- 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.

3. Adjustment of the air blower speed
The air blower operates only when
the engine is running (except when
the REST function is activated).
To adjust the fl ow of air, press on the
button:
to increase the air fl ow,
to decrease the air fl ow (this
button also has the REST

If you place the air blower on posi-
tion 0 , the system is deactivated.
The air blower display will be empty,
with the indication OFF.

Function for retaining
ventilation with the engine
switched off

The REST function is avail-
able when you switch on the ignition
and when you stop the engine.
This function allows you to retain ventilation
in the passenger compartment for a few
minutes, even with the engine stopped.
When you leave the vehicle, any
passengers present can still have
the benefi t of air circulation, even
though the engine is not running.
Engine stopped, ignition switched
on:
- The displays will light up, with the air blower shown empty as
long as the function is available.
- A press on the REST button acti- vates the function for a timing of
just a few minutes. Two blades of
the blower will fi ll to signify that
the function is active.
- It can be deactivated and reacti- vated during the timed period.
- At the end of the timed period, the display will go off. This button does not activate the air
conditioning, only the air blowers. In
the REST function, the air fl ow and
distribution are controlled automati-
cally and you cannot modify them.

On stopping the engine:
- The displays remain lit up, the blower is shown empty and the
function can be activated for
30 seconds.
- A press on the REST button dur- ing the next 30 seconds activates
the function for a timing of several
minutes. The duration and avail-
ability of the function are variable
according to the state of charge
of the battery (a protection to
guarantee engine starting). Two
blower blades fi ll up to signify that
the function is active. It remains
active, even after the doors have
been locked, until the end of the
timing.
- A further press before the end of the timed period stops the function
defi nitively. 4. Adjustment of the air
distribution

 Press on button 4 so that
the air fl ows scroll suc-
cessively on the display.
The air distribution you have chosen
is confi rmed by the lighting of the
corresponding warning lamps in the
display.
