4. Air intake / Air recirculation
The intake of exterior air prevents the
formation of mist on the windscreen
and side windows.

5. Air conditioning On / Off
The air conditioning is de-
signed to operate effectively
in all seasons, with the win-
dows closed.
It enables you to:


- lower the temperature, in summer,

- increase the effectiveness of the
demisting in winter, above 3 °C.


Switching on



Press the "A/C"
button, the button's
indicator lamp comes on.

Switching off



Press the "A/C"
button again, the
button's indicator lamp goes off.
Switching off may affect comfort levels
(humidity, condensation).
The recirculation of interior air isolates
the passenger compartment from exte-
rior odours and smoke.



Press the button to recir-
culate the interior air. The
indicator lamp comes on
to confi rm this.


Press the button again to permit the
intake of exterior air. The indicator
lamp goes off to confi rm this.

This function allows hot or cold
air to be delivered selectively
and more quickly.
Return to exterior air intake as soon as
possible to prevent deterioration of the
the air quality and the formation of mist.
The air conditioning does not
operate when the air fl ow adjust-
ment control 2
is in position " 0
".
To obtain cooled air more quick-
ly, you can use recirculation of
interior air for a few moments.
Then return to fresh air intake.

DUAL-ZONE DIGITAL AIR CONDITIONING

Automatic operation

We recommend the use of
one of the three AUTO modes
available: they provide opti-
mised regulation of the tem-
perature in the passenger
compartment according to the comfort
value that you have chosen.
These three modes automatically ad-
just the air fl ow, according to the de-
sired setting, while also maintaining the
desired comfort value.


Press the "AUTO"
button repeat-
edly:


- a fi rst indicator lamp comes on; the
"light" setting mode is selected,

- a second indicator lamp comes
on; the "medium" setting mode is
selected,

- a third indicator lamp comes on;
the "intense" mode setting is se-
lected.
The air conditioning system operates when the engine is running. When the engine is cold, the air
fl ow will reach its optimum level
progressively, taking account
of the weather and the desired
comfort level so as to avoid too
great a distribution of cold air.
On entering the vehicle, if the in-
terior temperature is much colder
or warmer than the comfort val-
ue, there is no need to change
the value displayed in order to
obtain the comfort required. The
system corrects the difference in
temperature automatically and
as quickly as possible.

1. Automatic comfort programme
This system is designed to operate ef-
fectively in all seasons, with the win-
dows closed.

COMFORT

For maximum cooling or heating
of the passenger compartment,
it is possible to exceed the mini-
mum value 14 or the maximum
value 28.



Turn control 2
or 3
to the left
until "LO"
is displayed or
to the right until "HI"
is dis-
played.

See "Front demisting - defrosting".



4. Automatic visibility programme

Manual operation

If you wish, you can make a different
choice from that offered by the system
by changing a setting. The the "AUTO"

indicator lamps go off; the other func-
tions will still be controlled automati-
cally.



Pressing the "AUTO"
button returns
the system to completely automatic
operation.
2. Driver's side adjustment
The driver and front pas-
senger can each adjust the
temperature to their require-
ments.



Turn control 2
or 3
to the left or to
the right respectively to decrease or
increase this value.
A setting around the value 21 provides
optimum comfort. However, depend-
ing on your requirements, a setting be-
tween 18 and 24 is normal.
You are advised to avoid a left / right
setting difference of more than 3.
3. Passenger's side adjustment
The value indicated on the display cor-
responds to a level of comfort and not
to a temperature in degrees Celsius or
Fahrenheit.






With Stop & Start, when dem-
isting has been activated, the
STOP mode is not available.

9. "REST" function: ventilation with
the engine off

On switching on the engine

are on.

- The screens go off at the end of this
period. Even with the engine is off,
you can operate the ventila-
tion for a few minutes.
For example, while you are
away from the vehicle, the
passengers can still enjoy some air cir-
culation without having the engine run-
ning.
This function is available after switching
on the ignition, as well as after stopping
the engine.
The period that the function is available

Air recirculation enables the passenger
compartment to be isolated from exte-
rior odours and smoke.



As soon as possible, press this but-
ton again to permit the intake of out-
side air and prevent the formation of
condensation. The indicator lamp in
the button goes off.


Avoid prolonged operation in in-
terior air recirculation mode (risk
of misting and deterioration of air
quality).

tion defi nitively: the control screens
go off and the function is no longer
available.


Turn the air fl ow control to
the left until all of the indi-
cator lamps go off.
This action switches off the air condi-
tioning and the ventilation.
Temperature related comfort is no long-
er assured but a slight fl ow of air, due
to the movement of the vehicle, can still
be felt.



Modify the settings (temperature,
air fl ow or air distribution) or press
the "AUTO"
button to reactivate the
system with the values set before it
was switched off.
This switch does not operate the
air conditioning, only the air fan.
When the "REST" function is ac-
tivated, you cannot modify the
temperature, air fl ow and distri-
bution settings: these are con-
trolled automatically according
to the ambient temperature.
This function is not available in
the STOP mode of Stop & Start.
