VENTILATION
A.
Sunshine sensor.
B.
Soft air diffusion grille.
The soft air diffusion grille located
in the centre of the dashboard
provides optimum distribution of
the air for the front seats.
This system eliminates unpleas-
ant air currents while maintaining
an optimum temperature in the
passenger compartment.
To open the soft air diffusion
grille, turn the wheel upwards.
To close the soft air diffusion grille,
turn the wheel fully downwards.
In very hot weather, to obtain
more satisfactory central and
side ventilation, it is advisable to
close the diffused air grille.
C.
Cooled glove box.
D.
Rear passenger vents.

Air conditioning
We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following functions:
air fl ow, temperature in the passenger
compartment and air distribution, by
means of various sensors (ambient
temperature, sunshine). This elimi-
nates any need for you to change
your settings other than the tempera-
ture value displayed.
)
Take care not to cover the sun-
shine 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 can only be lower than
the ambient temperature if the air
conditioning is on.
HEATING, VENTILATION
AND AIR CONDITIONING
RECOMMENDATIONS In order to be effective, the air
conditioning must be used with the
windows closed. If the vehicle has
been parked in the sun for a long
period and the interior tempera-
ture is very high, fi rst ventilate the
passenger compartment with the
windows open for a few minutes,
then close the windows.
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 engine
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
temperatures), switching off the air
conditioning saves engine power
and improves the towing capacity.
Air inlet
Check that the exterior grille for the
air inlet, at the bottom of the wind-
screen, 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 must be changed in line
with the vehicle’s servicing schedule
(see the vehicle’s servicing booklet).

DIGITAL AIR CONDITIONING (MONO-ZONE)
This is the normal sys-
tem operating mode.
In accordance with the
level of comfort chosen,
pressing this control,
confi rmed illumination
of indicator lamp A
, permits automatic
and simultaneous control of all of the
following functions:
- Air fl ow.
- Temperature in the passenger
compartment.
- Air distribution.
- Air intake.
- Air conditioning.
1. Automatic operation
It is advisable to leave all of the
vents open.
Simply pressing one of the controls,
with the exception of control 2
, switches
the system to manual mode.
Indicator lamp A
goes off.
2. Temperature adjustment
Turn control 2
to change
the temperature:
-
Clockwise to increase
the temperature.
- Anticlockwise to re-
duce the temperature.
The setting required is displayed.
The value indicated in the screen
corresponds to a level of comfort
and not to a temperature in degrees
Celsius or Fahrenheit, depending on
the screen confi guration.
A setting around the value 21
usu-
ally provides optimum comfort.
However, depending on your re-
quirements, a setting between 18
and 24 is normal.
On entering the vehicle, the interior
temperature may be much colder (or
warmer) than is comfortable. There
is no need to change the tempera-
ture displayed to obtain rapidly the
level of comfort required.
The automatic regulation of the air
conditioning will use its maximum
performance settings to correct the
temperature difference as quickly as
possible. The air conditioning system operates
with the engine running.
Mono-zone:
this is the overall
regulation of the temperature, distri-
bution and fl ow of air in the passenger
compartment.

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
conditioning must be used with the
windows closed.
Deactivating the air conditioning may
result in discomfort (temperature,
humidity, odour, condensation).
The indicator lamps 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 display of the distri-
bution of air to the windscreen and

independently 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 differ-
ent 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 door
mirrors demisting when you consider
this necessary as low current con-
sumption reduces fuel consumption.

When starting with the engine
cold, air fl ow will reach its opti-
mum level gradually to prevent an
excessive distribution of cold air.
When entering the vehicle after it
