MANUAL AIR CONDITIONING, HEATING SYSTEM (2/3)
Air recirculation operation
(isolation of the passenger
compartment)
Normal operation of the heating and
ventilation system is obtained using air
from outside.
Recirculation of air allows the external
atmosphere to be isolated (driving in
polluted areas, etc.).
Press button B to switch to isolation
mode. This function also allows the de-
sired comfort level to be achieved as
quickly as possible.
This starts or stops air recirculation.
Operating tell-tale lights up when the
function is operational. In this position
the air is taken from inside the passen-
ger compartment and is recycled with-
out letting air in from outside.
Prolonged use of this position can
lead to condensation forming on the
side windows and windscreen and
problems due to the use of non-
renewed air in the passenger com-
partment.
We therefore advise you to return
to normal mode (external air) as
soon as the air recirculation function
is no longer required, by pressing
button B again.

MANUAL AIR CONDITIONING, HEATING SYSTEM (3/3)
Adjusting the amount of air
blown into the passenger
compartment
Turn control A from 0 to 4. The passenger compartment is venti-
lated by blown air.
The blower determines how much air
enters but vehicle speed also has some
influence on this.
The further the control is positioned to
the right, the greater the amount of air
blown into the passenger compartment.
Switching air conditioning on
or off
(depending on the vehicle)
The air conditioning is switched on (in-
dicator light lit) or off (indicator light off)
using button D.
The air conditioning system is used
for:
– lowering the temperature inside the
passenger compartment;
– eliminating condensation more quickly.
Note: the air conditioning does not op-
erate if the exterior temperature is low
or the ventilation speed is less than 1.DA

are not displayed.
– press button 9 to increase the tem-
perature;
– press button 10 to decrease the tem-
perature.
Note: The maximum and minimum
settings of 15°C and 27°C allow the
system to produce a minimum or maxi-
mum temperature, whatever the ambi-
ent conditions.
In automatic mode (AUTO lit on the
display), all heating and air condi-
tioning functions are controlled by
the system.
When you modify certain functions,
AUTO goes out. Only the modified
function stops being controlled by
the system.
To reach and keep the chosen comfort
level and to maintain good visibility, the
system controls:
– ventilation speed;
– air distribution;
– air recirculation management;
– air conditioning start/stop;
– the air temperature.Automatic mode
Press button 3. AUTO lights up on dis-
play 4.
In most cases, the automatic climate
control system ensures a comfortable
temperature in the passenger compart-
ment, while maintaining good visibility
and optimising fuel consumption.
This is the recommended mode of
use.

Adjusting automatic mode
The system normally operates in auto-
matic mode but you can alter the stand-
ard settings used by the system (air
distribution, etc.). These options are
explained on the following pages.
Automatic mode is the recom-
mended mode of use
In most cases, the automatic cli-
mate control system ensures a com-
fortable temperature in the passen-
ger compartment, while maintaining
good visibility and optimising fuel
consumption.
The types of adjustments that can
be made are described in the follow-
ing pages.
Return to automatic mode as soon
as possible.
The displayed temperature values
show a comfort level.
When starting the engine, increas-
ing or decreasing the value dis-
played will not allow the com-
fort level to be reached any more
quickly. The system will always op-
timise the temperature increase or
decrease (the ventilation system
does not start instantly at maximum
speed: it gradually increases). This
may take several minutes.
Generally speaking, unless there is
a particular reason not to, the dash-
board air vents should remain open.

In automatic mode, depending on
the outside air conditions, the ven-
tilation may not start immediately at
maximum power but will increase
progressively until the engine tem-
perature is warm enough to heat the
passenger compartment air. This
may take from a few seconds to
several minutes.
Switching air conditioning on
or off
In automatic mode, the system switches
the air conditioning system on or off,
depending on the climate conditions.
Exit automatic mode by pressing
button 2: AUTO goes out on display 4
and AC OFF lights up.
Note: the “Clear View” function auto-
matically activates the air conditioning.
Press button 3 to return to automatic
mode.
Varying the ventilation speed
In automatic mode, the system uses
the most suitable amount of air to reach
and maintain the desired comfort level.
Exit automatic mode by pressing but-
tons 5 and 7.
These buttons allow you to increase or
decrease ventilation speed.

Clear View function
Press button 1; the indicator lights in
buttons 1 and 11 come on.
AUTO goes out on display 4.
This function rapidly demists/de-ices
the windscreen, the front side windows
and the door mirrors.
It imposes automatic operation of the
air conditioning and heating of the rear
screen and/or heated door mirrors, and
inhibits air recirculation. Press button
11 if you do not wish to
switch on the heated rear screen and/
or heated door mirrors.
Note: if you wish to reduce the air flow
(which may produce a certain amount
of noise in the passenger compart-
ment), press button 5.
To exit this function , press:
– button 1 again;
– button 3 (AUTO lights up on the dis-
play).
Air recirculation
Pressing button 12 activates air recir-
culation (the symbol lights up on the
display).
During recirculation, air is taken from
the passenger compartment and is re-
cycled, with no air being taken from out-
side the vehicle.
Air recirculation allows the external at-
mosphere to be cut off (when driving in
polluted areas, etc.).
Prolonged use of the air recirculation
mode may cause the windows to mist
up or lead to odours, as the air is not
renewed.
We therefore advise you to return to
normal mode (external air) as soon as
the air recirculation function is no longer
required, by pressing button 12 again.

Operating faults
As a general rule, contact your ap-
proved dealer in the event of an oper-
ating fault.
– Reduction in de-icing, demisting or air conditioning performance.
This may be caused by the passen-
ger compartment filter cartridge be-
coming clogged.
– No cold air is being produced .
Check that the controls are set cor-
rectly and that the fuses are sound.
Otherwise, switch off the system.
Presence of water under the
vehicle
After prolonged use of the air condi-
tioning system, it is normal for water
to be present under the vehicle. This is
caused by condensation.
AIR CONDITIONING: information and operating instructions (1/2)
Do not open the refriger-
ant fluid circuit. The fluid
may damage eyes or skin.
Fuel consumption
You will normally notice an increase in
fuel consumption (especially in town)
when the air conditioning is operating.
For vehicles fitted with air conditioning
with no automatic mode, switch off the
system when it is not required.
Advice for reducing consumption
and helping to preserve the environ-
ment
Drive with the air vents open and the
windows closed.
If the vehicle has been parked in the
sun, open the doors for a few moments
to let the hot air escape before starting
the engine.
Maintenance
Refer to the Maintenance Document
for your vehicle for the inspection fre-
quency.
Advice on use
In some situations (air conditioning off,
air recirculation activated, ventilation
speed at zero or low etc.), you may
notice that condensation starts to form
on the windows and windscreen.
If there is condensation, use the “Clear
View” function to remove it, then use
the air conditioning in automatic mode
to stop it forming again.
Do not add anything to the
vehicle’s ventilation circuit
(for example, to remove
bad odours).
There is a risk of damage or of
fire.
Use the air conditioning system reg-
ularly, even in cold weather, running
it at least once a month for approxi-
mately 5 minutes.
Vehicles equipped with
modeECO
Once activated, ECO mode may
reduce air conditioning perform-
ance. Please refer to the informa-
tion on “Driving advice, Eco-driving”
in Section 2.

the following information on label A af-
fixed inside the engine compartment.
The presence and location of the infor-
mation on label A depends on the ve-
hicle.
AAA
Do not open the refriger-
ant circuit . The fluid may
damage eyes or skin.
