Air conditioning
We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following func-
tions: air fl ow, temperature in the
passenger compartment and air
distribution, by means of various
sensors (exterior temperature, sun-
shine). This eliminates any need for
you to change your settings other
than the value displayed.

 Please do not block the sunshine
sensor A .
If you select the automatic mode
(by pressing the "AUTO" control)
and leave all of the vents open, opti-
mum comfort will be maintained and
humidity and condensation will be
removed regardless of the exterior
climatic conditions.
The temperature in the passenger
compartment cannot be lower than
the exterior temperature if the air
conditioning is not on.
VENTILATION, HEATING AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air con-
ditioning must be used with the win-
dows closed. If the vehicle has been
parked in the sun for a long period
and the interior temperature is very
high, ventilate the passenger com-
partment with the windows open for
a few minutes, then close the win-
dows.
To keep the air conditioning system
in good working order it is essential
that it is operated at least once a
month.
The air conditioning uses the en-
gine power during its operation. As a
result, the fuel consumption of the
vehicle increases.
In certain cases of particularly ardu-
ous use (e.g. towing the maximum
load on a steep gradient in high tem-
peratures), switching off the air condi-
tioning permits the recovery of engine
power and therefore increases the
towing capacity.
Air inlet
Check that the exterior grille for the air
inlet, at the bottom of the windscreen,
is clean and free of dead leaves,
snow, etc.
When washing the vehicle using a high
pressure nozzle, avoid spraying at the
air inlet. Air circulation
Maximum comfort is obtained by
means of a good distribution of air in
the passenger compartment, both in
the front and in the rear.
To obtain a uniform distribution of
air, take care not to block the ex-
terior air intake grille located at the
base of the windscreen, the vents,
the air outlets under the front seats
and the air extractor located behind
the fl aps in the boot.
The front and rear vents are fi tted
with thumbwheels to adjust the air
fl ow and direction. We recommend
that you leave all of the vents open.
Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter has to be changed in ac-
cordance with the vehicle mainte-
nance schedule (see: "Maintenance
and Warranty Guide").

It is possible to adjust one or more
functions manually, while leaving the
other functions in automatic mode.

 Press one of the controls, with
the exception of that which regu-
lates the temperature 2 . Indicator
light A switches off.
Switching to manual mode may re-
sult in discomfort (temperature, hu-
midity, odour, condensation) and is
not advantageous to comfort.
To return to automatic mode, press
the "AUTO" control.
3. Air distribution adjustment
 Press the controls 3
to change the distri-
bution of the air fl ow. 4. Air conditioning
The air conditioning will only oper-
ate when the engine is running. The
air blower control (air fl ow adjust-
ment) must be active to obtain air
conditioning.
Switching off the ventilation

 Turn control 5 to the
left until the fl ow of
air stops.

 Press control 4 .
Indicator light B
comes on.
5. Air fl ow adjustment
 Turn control 5 to the
right to increase the
air fl ow or to the left
to reduce it.
6. Front demisting - de-icing
In certain cases, the

"AUTO" mode may not
be suffi cient to demist or
de-ice the windows (hu-
midity, several passen-
gers, ice).

 Press control 6 to clear the win-
dows quickly. The indicator light
comes on.
The
"OFF" symbol is displayed on
the multifunction display.
This action switches off the display
and the indicator lights.
It deactivates all of the system's
functions, with the exception of the
rear screen demisting.
The temperature-related comfort is
no longer controlled (temperature,
humidity, odour, condensation).
Avoid driving for too long with the air
conditioning off.
In order to be effective, the air con-
ditioning must be used with the win-
dows closed.
Deactivating the air conditioning may
result in discomfort (temperature,
humidity, odour, condensation).
The indicator lights corresponding to
the distribution chosen come on:
- Windscreen and front side win- dows.
- Front ventilation (central and side vents and air diffusion grille
if open) and rear ventilation.
- Front and rear footwells.
Simultaneous displaying of the dis-
tribution of air to the windscreen and
side windows and of front and rear
ventilation is not possible. The air fl ow level is indicated by the
progressive lighting of the blocks of
the bar graph on the control panel
display
9 .
To prevent condensation and dete-
rioration of the quality of the air in
the passenger compartment, ensure
that an adequate fl ow of air is main-
tained.
To reactivate the air conditioning:

 Press control 1 .

It controls the temperature, air fl ow
and intake and distributes the ven-
tilation to the windscreen and front
side windows.
Resuming manual control exits from
"Demisting" mode. It must be can-
celled to permit renewal of the air
in the passenger compartment and
demisting.
Once the inconvenience has been
eliminated, pressing control 1 re-
turns the system to "AUTO" mode.

 Press control 7 , with
the engine running,
to demist the rear
screen and the mir-
rors. The indicator
light comes on.
Demisting is switched off automati-
cally to prevent an excessive con-
sumption of current and in relation
to the exterior temperature.
It may be stopped by pressing con-
trol 7 again or when the engine is
switched off.
7. Rear demisting - de-icing
The heated rear screen operates in-
dependently of the air conditioning
system.
8. Intake of exterior air/
Recirculation of interior air
This function enables you to isolate
the passenger compartment from
exterior fumes and odours. - When starting with the engine
cold, the fl ow will reach its op-
timum level gradually to pre-
vent an excessive distribution
of cold air.
- When entering the vehicle af- ter it has been parked for a
fairly long period, if the inte-
rior temperature is very diffe-
rent from your comfort setting
there is no need to change
the temperature displayed
in order to quickly reach the
level of comfort required. The
system automatically uses its
maximum performance to cor-
rect the difference in tempera-
ture as quickly as possible.
- The water resulting from the air conditioning condensation
is discharged via an open-
ing provided for this purpose;
therefore, a puddle of water
may form underneath the ve-
hicle when stationary.
- In all seasons, if the weather is cool, the air conditioning
is useful as it removes the
humidity from the air and the
condensation. Avoid driving
for prolonged periods with the
air conditioning switched off.
However, demisting resumes when
the engine is switched on again.
Switch off the rear screen and exte-
rior mirrors demisting when you con-
sider this necessary as low current
consumption reduces fuel consump-
tion.

 Press control 8 se-
veral times to set the
air intake mode, the
indicator light comes
on.

It must be cancelled as soon as
possible to permit renewal of the
air in the passenger compartment
and demisting.
