A few definitions…
This value may vary following a
change in the style of driving or
the relief, resulting in a signifi -
cant change in the current fuel
consumption.
If dashes are displayed continu-
ously while driving in place of the
digits, contact a CITROËN dealer
or a qualifi ed workshop. This function is only displayed
from 20 mph (30 km/h).
Range
(miles or km)
This indicates the distance
which can still be travelled
with the fuel remaining in the tank in
relation to the average fuel consump-
tion over the last few miles (kilometres)
travelled.
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 displayed
when it exceeds 60 miles (100 km).
Current fuel consumption
(mpg or l/100 km or km/l)
This is the average fuel con-
sumption during the last few
seconds.
Average fuel consumption
(mpg or l/100 km or km/l)
This is the average fuel con-
sumption since the last trip
computer zero reset.
Average speed
(mph or km/h)
This is the average speed calcu-
lated since the last trip computer
zero reset (ignition on).
Distance travelled
(miles or km)
This indicates the distance
travelled since the last trip
computer zero reset.
Stop & Start time counter
(minutes/seconds or hours/
minutes)
If your vehicle is fi tted with Stop & Start,
a time counter calculates the time spent
in STOP mode during a journey.
It resets to zero every time the ignition
is switched on with the key.
The fuel consumption of your ve-
hicle will be higher than the offi cial
fi gures obtained by CITROËN dur-
ing the fi rst 3 000 miles (5 000 km)
of the vehicle's life.

VENTILATION
Air intake
The air circulating in the passenger com-
partment is fi ltered and originates either
from the outside via the grille located at
the base of the windscreen or from the
inside in air recirculation mode.
Air treatment
The incoming air follows various routes
depending on the controls selected by
the driver:
- direct arrival in the passenger com-
partment (air intake),
- passage through a heating circuit
(heating),
- passage through a cooling circuit
(air conditioning).
Control panel
The controls of this system are grouped
together on control panel A
on the centre
console.

RECOMMENDATIONS FOR VENTILATION AND AIR
CONDITIONING
In order for these systems to be fully effective, follow the operation and
maintenance guidelines below:
)
To obtain an even air distribution, take care not to obstruct the exterior air
intake grilles located at the base of the windscreen, the nozzles, the vents
and the air outlets, as well as the air extractor located in the boot.
)
Do not cover the sunshine sensor, located on the dashboard; this is
used for regulation of the digital air conditioning system.
)
Operate the air conditioning system for at least 5 to 10 minutes, once or
twice a month to keep it in perfect working order.
)
Ensure that the passenger compartment fi lter is in good condition and have
the fi lter elements replaced regularly (refer to the "Checks" section).
We recommend the use of a combined passenger compartment fi lter.
Thanks to its special active additive, it contributes to the purifi cation of
the air breathed by the occupants and the cleanliness of the passenger
compartment (reduction of allergic symptoms, bad odours and greasy
deposits).
)
To ensure correct operation of the air conditioning system, you are
also advised to have it checked regularly as recommended in the
Maintenance and Warranty Guide.
)
If the system does not produce cold air, switch it off and contact a
CITROËN dealer or a qualifi ed workshop.
When towing the maximum load on a steep gradient in high temperatures,
switching off the air conditioning increases the available engine power and
so improves the towing ability.
If after an extended stop in sun-
shine, the interior temperature is
very high, fi rst ventilate the pas-
senger compartment for a few
moments.
Put the air fl ow control at a setting
high enough to quickly change
the air in the passenger compart-
ment.
The air conditioning system
does not contain chlorine and
does not present any danger to
the ozone layer.
The condensation created by the
air conditioning results in a dis-
charge of water under the vehicle
which is perfectly normal.
Stop & Start
The heating and air conditioning systems only work when the engine is run-
ning. To maintain a comfortable temperature in the passenger compartment,
you can temporarily deactivate the Stop & Start system (see "Driving").

The air distribution can be
adapted by placing the dial in
an intermediate position.
)

sition 5
to obtain a comfortable air
fl ow. This dial is used to arrange the distri-
bution of air in the passenger compart-
ment by combining several air outlets.

4. Air intake/Air recirculation
The intake of exterior air prevents the
formation of mist on the windscreen
and side windows.
5. Air conditioning On/Off
The air conditioning is de-
signed to operate effectively in
all seasons, with the windows
closed.
It enables you to:
- lower the temperature, in summer,
- increase the effectiveness of the
demisting in winter, above 3 °C.

button, the button's
indicator lamp comes on.
Switching off
)
Press the "A/C"
button again, the
button's indicator lamp goes off.
Switching off may affect comfort levels
(humidity, condensation).
The recirculation of interior air isolates
the passenger compartment from exte-
rior odours and smoke.
)
Press the button to recir-
culate the interior air. The
indicator lamp comes on
to confi rm this.
)
Press the button again to permit the
intake of exterior air. The indicator
lamp goes off to confi rm this.
This function allows hot or cold
air to be delivered selectively
and more quickly.
Return to exterior air intake as soon
as possible to prevent deterioration of
the the air quality and the formation of
mist. The air conditioning does not
operate when the air fl ow adjust-
ment control 2
is in position " 0 ".

DUAL-ZONE DIGITAL AIR CONDITIONING
Automatic operation
We recommend the use of
one of the three AUTO modes
available: they provide opti-
mised regulation of the tem-
perature in the passenger
compartment according to the comfort
value that you have chosen.
These three modes automatically adjust
the air fl ow, according to the desired set-
ting, while also maintaining the desired
comfort value.
)
Press the "AU TO "
button repeatedly:
- a fi rst indicator lamp comes on; the
"light" setting mode is selected,
- a second indicator lamp comes
on; the "medium" setting mode is
selected,
- a third indicator lamp comes on;
the "intense" mode setting is se-
lected.
The air conditioning system operates when the engine is running. When the engine is cold, the air
fl ow will reach its optimum level
progressively, taking account
of the weather and the desired
comfort level so as to avoid too
great a distribution of cold air.
On entering the vehicle, if the in-
terior temperature is much colder
or warmer than the comfort value,
there is no need to change the
value displayed in order to obtain
the comfort required. The system
corrects the difference in temper-
ature automatically and as quickly
as possible.

effectively in all seasons, with the windows
