bution selected:
§The air flow is directed towards
the outlet located on the top of
the dashboard (position which allows
the greatest distribution of ventilation).
„the air flow is directed towards
the dashboard air vents (posi-
tion which allows the passenger com -
partment to be heated or cooled as
quickly as possible).
ƒthe air flow is directed mainly
towards the passenger foot -
wells.
‚the air flow is directed towards
the side window and wind -
screen demisting vents (position which
prevents condensation forming).
Stopping the systemPress the bottom of button 4 several
times to stop the system. To start, press

Switching air conditioning on
or off
The air conditioning is switched on (in-
dicator light illuminated) or off (indicator
light extinguished) using button 1.
The air conditioning system is used
for:
– lowering the temperature inside the
passenger compartment;
– e l i m i n a t i n g c o n d e n s a t i o n m o r e
quickly.
The air conditioning does not operate
when the exterior temperature is low.
Adjusting the air temperatureUse control 2 to set the required tem -
perature. The more squares lit on the
display, the higher the temperature.
The fewer squares lit on the display, the
lower the temperature.
Distribution of air in the
passenger compartment
There are six air distribution options.

Adjusting the ventilation
speed
Normal use
Pressing on the top or bottom of
button 4 increases or decreases the
ventilation speed: the more blades of
the ventilation fan seen in zone b are
lit, the higher the ventilation speed.
Note: to maintain a comfortable level,
we advise you to use a position be -
tween 3 and 5, half-lit. Position 0 (ventilation fan in zone b
empty)
the system is deactivated: the ventila
-
tion speed for the passenger compart-
ment air is zero (vehicle stationary),
you can however still feel a slight flow
of air when the vehicle is moving.
clear View function
Press button 7: the integrated indicator
light comes on.
This function quickly demists and de -
ices the windscreen, the rear screen,
the front side windows, and the door
mirrors (depending on the vehicle). The
air conditioning and rear screen de -ic -
ing functions must be activated.
Press button 6 to stop the heated rear
screen operating, and the integrated in-
dicator goes out.
To change the ventilation speed: press
button 4.
To exit this function , press button 7
again.
Switching the air
recirculation on
Press air recirculation button 8: the in -
dicator light comes on.
In these conditions air is taken from the
passenger compartment and is recircu-
lated, with no air being taken from out-
side the vehicle.
Air recirculation is for:
– isolating the vehicle from the exter -
nal atmosphere (driving in polluted
areas, etc.);
– lowering the passenger compart -
ment temperature as quickly as pos-
sible.
Prolonged use of air recirculation
can lead to condensation form -
ing on the side windows and wind -
screen, and discomfort due to the
use of non-renewed air in the pas -
senger compartment.
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 8 again.

Automatic mode
The automatic climate control system
guarantees comfort in the passen -
ger compartment and good visibility
(except in the event of extreme condi -
tions), whilst optimising consumption.
The system controls the ventilation
speed, air distribution, air recircula -
tion, and starting and stopping the air
conditioning and air temperature. This
mode consists of a choice of three pro-
grammes:
A uTo : allows the selected comfort
level to be best attained, depending on
the exterior conditions. Press button 3.
SoFT: gently brings the temperature to
the desired comfort level. The comfort
level is then maintained gently and si -
lently. Press button 2.
FAST: emphasises the actions of the
system to reach the desired comfort
level more quickly. Use this programme
when you have passengers in the rear.
Press button 4.

Temperature adjustment
Press either button 1 or 5 to increase
or decrease the temperature. Pressing
button 3 for more than 2 seconds sets
the passenger temperature to the driv-
er’s temperature.
Special note: the highest and lowest
settings allow the system to produce
maximum hot or cold temperature levels
(“LO” and “HI” display on screen 12).
Stopping the system
Press the bottom of button 11 sev -
eral times to stop the system. To start
it, press the top of switch 11 or one of
switches 2, 3 or 4.7

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.
Switching air conditioning on
or off
In automatic mode, the system switches
the air conditioning system on or off,
depending on the climate conditions.
Press button 10 to switch off the air
conditioning.
Varying the ventilation speed
In automatic mode, the system uses
the most suitable amount of air to reach
and maintain the desired comfort level.
You can always adjust the ventilation
speed by pressing on the top or bottom
of button 11 to increase or decrease the
ventilation speed.
In this situation, the ventilation speed,
which is no longer automatically con -
trolled, appears on the display.
Where possible, it is recom -
mended that automatic mode is
used by selecting one of the auto-
matic programmes: AuT o, SoFT
or FAST.
In automatic mode (indicator light
for button 3 on), all heating and air
conditioning functions are controlled
by the system.
You can also change the system
selection, in this case, indicator
light for button 3 will go out and
the changed function, which is no
longer controlled by the system, is
shown on display 12.
To return to automatic mode, press
one of programmes: AuTo , S o FT
or FAST.

Air recirculation
This function is controlled automati -
cally, but it can also be activated manu-
ally.
Automatic operation
Your system is fitted with a sensor which
measures the air on a quality index. it
may therefore decide to activate air re-
circulation, in this case the integrated
indicator does not come on .Note:
–
during recirculation, air is taken from
the passenger compartment and
is recycled, with no air being taken
from outside the vehicle;
– air recirculation allows the external
atmosphere to be cut off (when driv-
ing in polluted areas, etc.).
Manual use
Pressing button 9 allows air recircula -
tion to be activated, in this case, the
integrated indicator comes on ;
Prolonged use of this position may lead
to odours, caused by non-renewal of
air, and the formation of condensation
on the windows.
We therefore advise you to return to au-
tomatic mode as soon as the air recir-
culation function is no longer required,
by pressing button 9 again.

The demisting/de-icing will still take
priority over the air recirculation.
In some situations (high humidity,
etc.) air recirculation is not activated
automatically, to ensure visibility
remains the priority (ventilation is
maintained using air from the out -
side).
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.

are not stuck by ice (to
avoid the risk of the motor
overheating).
– Check the condition of the wiper
blades.
Replace the wiper blades as soon
as they begin to lose efficiency
(approximately once a year).
Whilst changing the blade, take care
not to drop the arm onto the window
after it has been removed as this
may break the window.
