A few definitions…
Range
(miles or km) Current fuel consumption
( m p g o r l / 1 0 0 k m o r k m / l )
Average fuel
consumption
( m p g o r l / 1 0 0 k m o r k m / l ) Distance travelled
(miles or km) Average speed
( m p h o r k m / h )
This indicates the distance which
can still be travelled with the fuel re-
maining in the tank in relation to the
average fuel consumption over the
last few miles (kilometres) travelled. T h i s v a l u e m a y v a r y f o l l o w i n g a

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 re-
sult, the fuel consumption of the ve-
hicle 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.

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 screen is clear, press-
ing control 1 returns the system to
"AUTO" mode.
Press control 7 , with
the engine running,
to demist the rear
screen and the door
mirrors. The indica-
tor lamp comes on.
Demisting is switched off automati-
cally to prevent an excessive con-
sumption of current and in relation
to the ambient temperature.
It may be stopped by pressing con-
trol 7 again or when the engine is
switched off.
7. Rear demisting - defrosting
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
c o l d , t h e fl o w w i l l r e a c h i t s o p -
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.
Press control 8 sev-
eral times to set the
air intake mode, the
indicator lamp comes
on.
It must be cancelled as soon as
possible to permit renewal of the
air in the passenger compartment
and demisting.

mum level gradually to prevent an
excessive distribution of cold air.
When entering the vehicle after it
has been parked for a fairly long
period, if the interior temperature
is very different from your comfort
setting there is no need to change
the temperature displayed in or-
der to quickly reach the level of
comfort required. The system
automatically uses its maximum
performance to correct the differ-
ence in temperature as quickly as
possible.
The water resulting from the air
conditioning condensation is dis-
charged via an opening provided
for this purpose; therefore, a pud-
dle of water may form underneath
the vehicle when stationary.
In all seasons, if the weather is
cool, the air conditioning is use-
ful as it removes the humidity
from the air and the condensa-
tion. Avoid driving for prolonged
periods with the air conditioning
switched off.
9. Front demisting - defrosting
In certain cases, the
"AUTO" mode may not
b e s u f fi c i e n t t o d e m i s t o r
defrost the windows (hu-
midity, several passen-
gers, ice).
Press control 9 to clear the win-
dows quickly. The indicator lamp
comes on.
This system controls the temperature,
a i r fl o w a n d i n t a k e a n d d i s t r i b u t e s t h e
ventilation to the windscreen and front
side windows.
Resuming manual control exits from
the "Demisting" mode. It must be
cancelled as soon as possible to
permit renewal of the air in the pas-
senger compartment and demisting.
Pressing one of the controls 1a and
1b returns the system to the "AUTO"
mode.
8. Rear demisting - defrosting
Switch off the rear screen and exterior
mirrors demisting when you consider
this necessary as low current con-
sumption reduces fuel consumption.
The heated rear screen
operates independently
of the air conditioning
system.
Press control 8 , with the en-
gine running, to demist the rear
screen and the mirrors. The indi-
cator lamp comes on.
Demisting is switched off automati-
cally to avoid excessive consump-
tion of current and depending on the
exterior temperature.
It may be stopped by pressing con-
trol 8 again or when the engine is
switched off.
In this latter case, the demisting re-
sumes if the engine is switched on
again within one minute.
