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-
t i o n s : a i r fl o w , t e m p e r a t u r e i n t h e
passenger compartment and air
distribution, by means of various
sensors (ambient temperature, sun-
shine). This eliminates any need for
you to change your settings other
than the temperature value dis-
played.
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, optimum comfort
will be maintained and humidity and
condensation will be removed regard-
less 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 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
h i g h , fi r s t v e n t i l a t e t h e p a s s e n g e r
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
t h e fl a p s i n t h e b o o t .

with thumbwheels to adjust the air
fl o w a n d d i r e c t i o n . W e r e c o m m e n d
that you leave all of the vents open.

FUEL TANK
Capacity of the tank: approxi-
mately 71 litres.
Low fuel level When the minimum level
in the tank is reached, this
warning lamp comes on
in the instrument panel,
accompanied by an audible warning
and a message on the multifunction
s c r e e n . W h e n i t fi r s t c o m e s o n , t h e r e
remains around 5 litres of fuel in the
tank.
You must refuel to avoid running out
of fuel.
Press at the top left corner, then
pull open from the left.

after the third cut-off ; this could
cause your vehicle to malfunc-
tion.
While you are refuelling, the engine
must be stopped and the ignition
switched off.
For a petrol engine with a catalytic
converter, unleaded fuel is compul-
sory.
Opening the fuel flap Additions of fuel must be of at least
5 litres to be taken into account by
the fuel gauge.
T h e fi l l e r n e c k i s n a r r o w e r t o e n -

zles can be put in.

vacuum, which is entirely normal,
is caused by the sealing of the fuel
