A few definitions… Range
(km or miles)
This fi gure may vary following a
change in the style of driving or
the relief, resulting in a signifi cant
change in the current consump-
tion.
When the range falls below 20 miles
(30 km), dashes are displayed. After
fi lling with at least 5 litres of fuel,
the range is recalculated and is dis-
played when it exceeds 60 miles
(100 km).
If dashes are displayed continu-
ously while driving in place of the
digits, contact a CITROËN dealer.
This indicates the distance which
can still be travelled with the fuel re-
maining in the tank in relation to the
average consumption over the last
few miles (kilometres) travelled.
Current consumption
(l/100 km or km/l or mpg)
Average consumption
(l/100 km or km/l or
mpg)
This is the average fuel consump-
tion since the last trip computer zero
reset.
Average speed
(km/h or mph)
This is the average speed calcula-ted since the last trip computer zero reset (ignition on).
Distance travelled
(km or miles)
This indicates the distance travelled since the last trip computer zero re-set.
Distance remaining
to destination
(km or miles)
This is the distance remaining to be
travelled to the fi nal destination. It is
either calculated instantly by the navi-
gation system, if guidance is acti-
vated, or entered by the user.
If the distance is not entered, dashes
are displayed in place of the digits.
This function is only displayed from
20 mph (30 km/h).
This is the average fuel consump-
tion during the last few seconds.

RECOMMENDED SETTINGS FOR THE VENTILATION, HEATING AND AIR CONDITIONING 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.
Air distribution
- Windscreen demisting/defrosting vents.
- Front side windows demisting/ defrosting vents.
- Adjustable and closing side air vents.
- Adjustable and closing central air vents.

Air conditioning
To ensure that your system operates
correctly, it is recommended to have
it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the windows
closed.
If after a lengthy stop in bright sunlight
the interior temperature is excessive,
ventilate the passenger compartment
by opening the windows for a few
moments, then close them again.
The air conditioning operates by using
power from the engine. This results in
a slight increase in fuel consumption.
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 servicing
schedule (see "Maintenance and
Warranty Guide").
Air circulation
Maximum comfort is obtained when
there is a good distribution of air in
the passenger compartment, both in
the front and in the rear.
For optimum operating effi ciency,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents have grilles
and thumbwheels to adjust the air fl ow
and direction (up-down, right-left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunlight sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

1 - Adjustment of the air
distribution

Demisting - Defrosting.

Flow to the windscreen
and front side windows.

Distribution to the wind-
screen, side windows and
footwells.

Flow to front and rear pas-
senger footwells.
Distribution from the air blower can
be altered at will by placing the dis-
tribution control 1 in an intermediate
position. 2 - Air recirculation
3 - Heater blower control
The air blower operates only when the
engine is running. For optimum com-
fort in the passenger compartment,
the control should not remain in posi-
tion
0 (position 1 minimum ).
This position is for excluding
disagreeable odours or emis-
sions coming from outside
the cabin. With a press on
control 2 , the entry of air from outside
is closed off, the lamp comes on.
This should be cancelled as soon as
possible to prevent misting and to
allow fresh air into the cabin.
To deactivate air recirculation, press
again on control 2 , the warning lamp
goes out.

 Operate the air conditioning by
pressing the control 6 , the warning
lamp comes on.
The system should not be in air re-
circulation.
5 - Rear screen demisting
Can only be operated with the engine

One press on control 5 acti-
vates the electric demisting of
the rear screen and, accord-
ing to version, the exterior
rear view mirrors. The warning lamp
comes on.
It switches off automatically to avoid
excessive power consumption.
One press stops the demisting.
A further press starts it again.
If the engine is stopped before the
end of demisting, the operation will
resume the next time the engine
is started. 6 - Air conditioning
The air conditioning will only operate
when the engine is running.
Press on control 6 The warn-
ing lamp comes on.
For air conditioning, the air
blower control 3 must not be
on position "0" .
Air conditioning is obtained by mixing
the warm air with refrigerated air. The
temperature control 4 adjusts the air
conditioning provided the control 6 is
operational.
4 - Temperature control
The heating/ventilation and manual
air conditioning systems can only
function with the engine running.

AUTOMATIC AIR CONDITIONING 1 - Automatic operation
This system automatically regulates
temperature, air fl ow and air distribu-
tion in the passenger compartment
according to the temperature selected
(for each side, right and left).
It provides an optimum level of comfort
regardless of the climatic conditions,

by permanent use of the automatic
air conditioning mode (press the AUTO
button ) and with all the vents open.
Having no airfl ow prevents the air con-
ditioning and the system in general
from working.

To prevent misting of the interior
of the vehicle in cold and damp
conditions, the use of AUTO
mode is recommended. 2 - Adjustment of
temperature on left
hand side
To set and display the de-
sired temperature, rotate
control 2 or 3 :
The display HI (high) corre-
sponds to a demand for maxi-
mum heating (above 27).
The display LO (low) cor-
responds to a demand for
maximum air conditioning
(below 15).
3 - Adjustment of
temperature on right
hand side
- To the left to lower the tempera- ture
- To the right to raise the tempera- ture
The difference between the tempera-
tures on the right and on the left can-
not be greater than 3 degrees.
A setting around 21 will provide a tem-
perature that is comfortable. Depending
on your requirements, an adjustment
between 18 and 24 is normal.
A press on this control,
confi rmed by the display of

"A/C" and "AUTO" , auto-
matically manages all the
5 following functions according to
the temperature chosen:
- Flow of air.
- Cabin temperature.
- Distribution of air.
- Air conditioning.
- Recycling of air.
To enable the system to operate, all
the air vents should be kept open. This is the normal operating
mode.
