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.

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.

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
running.
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

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.

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.

 When you enter the vehicle, the
temperature inside the vehicle may
be much colder (or warmer) than a
comfortable temperature. There is
no point in modifying the displayed
temperature to try to attain the de-
sired level of comfort. The system
operates automatically to compen-
sate this temperature discrepancy
as rapidly as possible.

 When starting the engine from
cold, in order to avoid distributing
too much cold air, the blower will
attain its optimum level gradually.

Each of the functions 4 , 6 and 7 can
be adjusted manually.

blocked off and the associated
symbol is displayed.
This function can also be accessed
by pressing the appropriate button
on the steering wheel.
While retaining the other settings,
this position excludes disagreeable
odours or emissions coming from
outside. It should be cancelled as
soon as possible to prevent misting
and to allow fresh air into the cabin.

It may be refrigerated, depending on
your vehicle’s equipment, by a ven-
tilation duct that can be closed off
manually.
With the air conditioning, this duct
distributes the same cooled air as
the vents in the passenger compart-
ment.
The refrigeration of your glovebox
only operates when the engine is run-
ning and the air conditioning is on.
The lamp comes on auto-
matically when the lid is
opened. For safety reasons, the
glovebox should remain
closed when the vehicle is

TYRE UNDER-INFLATION DETECTION
Sensors fi tted in each valve check
the tyre pressure during driving and
trigger a warning in the event of
malfunction (speed above 12 mph
(20 km/h)).
Flat tyre The tyre under-infl ation detection
system is an aid to driving which
does not replace the vigilance or
responsibility of the driver. Puncture
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The
STOP warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punc-
tured or very defl ated tyre), and
have the tyre pressure checked as
soon as possible.
Sensor(s) not detected or faulty
The service warning
lamp comes on in the
instrument panel, ac-
companied by an audible
signal and a message on
the multifunction screen
locating the wheel or wheels which
are not detected or indicating a fault
in the system.
Have the faulty sensor(s) checked
by a CITROËN dealer. All repairs and changing of tyres
on a wheel fi tted with this system
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
by your vehicle (example: fi tting
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not eliminate
the need to have the tyre pres-
sure checked regularly (refer to the
"Technical data - § Identifi cation
markings" section) to ensure that
the optimum dynamic performance
of the vehicle is maintained and
prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (heavy load, high
speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detection
system may experience temporary
interference due to radio-electric
emissions on a frequency close to
that used by the system.
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired) or
when one or more wheels without a
sensor are fi tted.
The spare wheel is not fi tted with a
sensor.
