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
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" button
will realign the temperature for all
passengers with the preferences of
the driver.

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
function).
The level of air fl ow is indicated on
the display by the progressive fi lling
of the ventilator blades.
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 availa-
ble when you switch on the ignition
and when you stop the engine.
This function allows you to retain
ventilation in the passenger com-
partment 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 timing.
- At the end of the timing, the dis- play 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 during the next 30 seconds ac-
tivates the function for a timing
of several minutes. The dura-
tion and availability of the func-
tion 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 af-
ter the doors have been locked,
until the end of the timing.
- A further press before the end of the timing defi nitively stops the
function. 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.
There are 7 possible adjustments.
5. Air recirculation
This button activates the recircula-
tion of air within the passenger com-
partment and also has an automatic
function.

Entry of air in automatic
mode (activated by default, in
automatic comfort regulation) According to version, the automatic
mode makes use of an air quality sen-
sor. This analyses the air and isolates
the passenger compartment from the
exterior as soon as it detects the pres-
ence of pollutants. Then it automatically
activates recirculation of cabin air.
