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
vehicle will be higher than
the offi cial fi gures obtained
by CITROËN during the fi rst
3 000 miles (5 000 km) of the
vehicle's life.

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" sec-
tion).
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 set-
ting high enough to quickly
change the air in the passenger
compartment.
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
discharge of water under the ve-
hicle 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").

7. Air fl ow adjustment


)
Turn this control to the left
to decrease the air fl ow or
to the right to increase the
air fl ow.
The air fl ow indicator lamps, between
the two fans, come on progressively in
relation to the value requested. For maximum cooling or heating
of the passenger compartment,
it is possible to exceed the mini-
mum value 14 or the maximum
value 28.


)
Turn control 2
or 3
to the left
until "LO"
is displayed or
to the right until "HI"
is dis-
played.

See "Front demisting - defrosting".



4. Automatic visibility programme


Manual operation

If you wish, you can make a different
choice from that offered by the system
by changing a setting. The the "AUTO"

indicator lamps go off; the other func-
tions will still be controlled automati-
cally.


)
Pressing the "AUTO"
button returns
the system to completely automatic
operation.

5. Air conditioning On/Off


)
Press this button to switch
off the air conditioning.
Switching the system off could result in
discomfort (humidity, condensation).


)
Press this button again to return to
automatic operation of the air con-
ditioning. The indicator lamp on the
"A/C"
button comes on.


)
Press one or more but-
tons to direct the air fl ow
towards:
6. Air distribution adjustment


- the windscreen and side windows
(demisting or defrosting),

- the outer and centre air vents,

- the footwells.

You can combine the three orientations
to obtain the desired air distribution.
2. Driver's side adjustment
The driver and front pas-
senger can each adjust the
temperature to their require-
ments.


)
Turn control 2
or 3
to the left or to
the right respectively to decrease or
increase this value.
A setting around the value 21 provides
optimum comfort. However, depend-
ing on your requirements, a setting be-
tween 18 and 24 is normal.
You are advised to avoid a left/right set-
ting difference of more than 3.
3. Passenger's side adjustment
The value indicated on the display cor-
responds to a level of comfort and not
to a temperature in degrees Celsius or
Fahrenheit.






With Stop & Start, when dem-
isting has been activated, the
STOP mode is not available.
8. Air intake/Air recirculation


)
Press this button for recir-
culation of the interior air.
The indicator lamp in the
button comes on.
Air recirculation enables the passenger
compartment to be isolated from exte-
rior odours and smoke.


)
As soon as possible, press this but-
ton again to permit the intake of out-
side air and prevent the formation of
condensation. The indicator lamp in
the button goes off.

Switching the system off

Avoid prolonged operation in in-
terior air recirculation mode or
driving for long periods with the
system off (risk of condensation
and deterioration of air quality).
9. "REST" function: ventilation with
the engine off

On switching on the engine



- The control screens come on: the
function is available.

- Pressing the REST
button activates
the ventilation for a few minutes.
Activation of the function is con-
fi rmed by the display of two dashes
in the control screens and four air
fl ow level indicator lamps.

- The function can be deactivated and
reactivated if the control screens
are on.

- The screens go off at the end of this
period.
On stopping the engine



- While the control screens remain
on: the function is available.

- Pressing the REST
button activates
the ventilation for a few minutes.
Activation of the function is con-
fi rmed by the display of two dashes
in the control screens and four air
fl ow level indicator lamps.
Locking the vehicle has no effect on
this function.

- The control screens go off at the
end of this period.
Pressing again before the end of
the period interrupts off the ventila-
tion defi nitively: the control screens
go off and the function is no longer
available.

)
Turn the air fl ow control to
the left until all of the indi-
cator lamps go off.
This action switches off the air condi-
tioning and the ventilation.
Temperature related comfort is no longer
assured but a slight fl ow of air, due to
the movement of the vehicle, can still
be felt.


)
Modify the settings (temperature,
air fl ow or air distribution) or press
the "AUTO"
button to reactivate the
system with the values set before it
was switched off.
This switch does not operate the
air conditioning, only the air fan.
When the "REST" function is ac-
tivated, you cannot modify the
temperature, air fl ow and distri-
bution settings: these are con-
trolled automatically according
to the ambient temperature.
This function is not available in
the STOP mode of Stop & Start.
Even with the engine is off,
you can operate the ventila-
tion for a few minutes.
For example, while you are
away from the vehicle, the
passengers can still enjoy some air cir-
culation without having the engine run-
ning.
This function is available after switching
on the ignition, as well as after stopping
the engine.
The period that the function is available
depends on the state of charge of the
battery.
You can activate the "REST" func-
tion while the air conditioning control
screens are on.
