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
sensor. This analyses the air and
isolates the passenger compart-
ment from the exterior as soon as it
detects the presence of pollutants.
Then it automatically activates recir-
culation of cabin air.
