f you place the air flow control in
position 0 , the system is deactivated.
A slight flow of air can still be felt,
resulting from the for ward movement of
the vehicle.
Avoid driving too long with the ventilation
off (risk of misting and deterioration of air
quality).

in the passenger compartment by combining
several air outlets. Windscreen and side windows.
Windscreen, side windows and
footwells.
Footwells.
Central and side air vents.
The air distribution can be
adapted by placing the dial in an
intermediate position.
Air intake/Air recirculation
The intake of exterior air prevents the formation
of condensation on the windscreen and side
windows.
Recirculation of the interior air isolates the
passenger compartment from exterior odours
and fumes.This function allows hot or cold air to be
delivered selectively and more quickly.
Return to exterior air intake as soon as
possible to avoid deterioration of the air
quality and the formation of condensation.

a i r.
Switching off
F Press the A/C button again,
the button's indicator lamp
goes off.
Switching the system off could result in
discomfort (humidity, condensation).
Automatic operation
Automatic comfort programme
We recommend using one of the three AUTO
modes available: they provide optimised
regulation of the temperature in the passenger
compartment according to the comfort value
that you have chosen.
These three modes automatically adjust the
air flow, according to the desired setting, while
also maintaining the desired comfort value.
This system is designed to operate effectively
in all seasons, with the windows closed. F

P
ress the AUTO button in
succession:
-

In cold weather and when the engine
is cold, the air flow will gradually reach
its optimum level, taking account of the
weather and the desired comfort level so
as to avoid distributing too much cold air.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort value, there is no need
to change the value displayed in order to
obtain the desired comfort. The system
corrects the difference in temperature
automatically and as quickly as possible.
Temperature adjustment on driver/
passenger side
The driver and front passenger can each set
the temperature to suit their requirements.
The value shown on the display is a level
of comfort, not a temperature in Celsius or
Fahrenheit.F

T
urn the dial to the left to lower
the value and to the right to
raise it. A setting around the value 21 provides
optimum comfort. However, depending on your
requirements, a setting between 18 and 24 is
normal.
It is also recommended to avoid a left /right
setting difference of more than 3.
Automatic visibility programme
For more information on Front
demist - defrost
, refer to the
corresponding section.
With Stop & Start, when demisting/
defrosting has been activated, STOP
mode is not available.

from that offered by the system by changing
a setting. The " AUTO" button indicator lamps
go off; the other functions will continue to be
managed automatically.
F

P
ressing the "AUTO" button
returns the system to full
automatic operation. For maximum cooling or heating of the
passenger compartment, it is possible

-

t
he windscreen and side
windows (demisting or
def r o st ing),
-

t
he outer and centre air vents,
-

t
he footwells.
You can combine the three directions to obtain
the desired air distribution.
Adjusting the air flow
F Turn this control to the left to decrease the air flow or to the
right to increase the air flow.
The air flow indicator lamps between the two
fans come on progressively according to the
value requested.
Air intake/Air recirculation
F Press this button to recirculate the interior air. The button's
indicator lamp comes on.
Air recirculation enables the passenger compartment
to be isolated from exterior odours and smoke.
F As soon as possible, press this button again to permit
the intake of outside air and
prevent the formation of
condensation. The button's
indicator lamp goes off.
Avoid prolonged operation in interior air
recirculation mode (risk of misting and
deterioration of air quality).
"REST" function: ventilation with the
engine off
Even with the engine is off, you can operate the
ventilation for a few minutes.
For example, if you leave the vehicle,
ventilation can be provided to the passengers
who stay inside without having to start the
engine.
This function is available after switching on the
ignition, as well as after stopping the engine.
The availability period of the function depends
on the state of charge of the battery.
You can activate the "REST" function as long
as the air conditioning control displays are on. When the ignition is switched on

Recommendations for ventilation and air conditioning
In order for these systems to be fully
effective, follow the operation and
maintenance guidelines below:
F
T
o ensure that the air is distributed
evenly, keep the external air intake
grilles at the base of the windscreen,
the nozzles, the vents, the air outlets
and the air extractor in the boot free
from obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used
for regulation of the automatic air
conditioning system.
F

O
perate the air conditioning system for
at least 5 to 10 minutes once or twice
a month to keep it in per fect working
o r d e r.
F

E
nsure that the passenger
compartment filter is in good condition
and replace the filter elements
periodically. We recommend the use of
a combined passenger compartment
filter. Thanks to its special active
additive, it helps both to purify the air
breathed by the occupants and to keep
the passenger compartment clean
(reduction of allergic symptoms, bad
odours and greasy deposits). F
T o ensure correct operation of the
air conditioning system, you are also
advised to have it checked regularly as
recommended in the Maintenance and
Warranty Guide.
F

I
f the system does not produce cold air,
switch it off and contact the dealer network
or a qualified workshop.
When towing the maximum load on a steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power and so improves the towing
ability.
To avoid the windows misting up and
deterioration in the quality of the air:
do not drive for too long with the ventilation
switched off.
Do not keep air recirculation set for an
extended period. If after an extended stop in sunshine, the
interior temperature is very high, first air
the passenger compartment for a few
moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
The condensation created by the air
conditioning results in a discharge of
water under the vehicle which is per fectly
normal.
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
To maintain a comfortable temperature
in the passenger compartment, you can
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.
