2. Adjusting the temperature.
3. Adjusting the air flow.
4. Adjusting the air distribution.
5. Air intake/Air recirculation.
Air conditioning
The air conditioning only works with the engine
running.
The fan must be set to at least 1.
Pressing the button switches the air
conditioning on; the LED is lit.
Pressing the button again switches the function
off; the LED goes out.
Temperature
F Turn the dial to select a position between blue
(cold) and red (hot) so as to
adjust the temperature to your
requirements.
Air flow
F Turn the control to your chosen position to obtain sufficient air
flow for your comfort.
If you place the air flow control at
position 0 (off), the thermal comfort is no
longer controlled. However, a slight flow of
air can still be felt due to the movement of
the vehicle.
Air distribution
The air supply distribution is directed by the
control turned towards: the footwells,
the windscreen, footwells and side
windows,
the windscreen and side windows.
Air intake/Air recirculation
The intake of exterior air prevents the formation
of mist on the windscreen and side windows.
Recirculation of the interior air isolates the
passenger compartment from exterior odours
and fumes.
Used with the air conditioning switched on
and the fan setting (from 1
to 4), recirculation
enables you to obtain the required ambient air
comfort level with both hot or cold settings.
Return to exterior air intake as soon as possible
to avoid deterioration of the air quality and the
formation of mist.

Additional heating
systems
Additional heating
This is passenger compartment heating,
additional to the standard equipment.
It can operate independently of the engine.
Additional heater or
programmable additional
heating
This is an additional, programmable and
separate system which heats the Diesel engine
hot coolant loop to make starting easier.
It improves the demisting and defrosting
per formance and that of the heated seats, if
fitted to the vehicle.
Automatic additional
heating
This is an additional system which starts
automatically when the ignition is switched
on. Its activation depends on the exterior
temperature and the temperature inside the
vehicle.
It switches off automatically once the heating
system is started manually. The passenger compartment heating is brought
up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle.
Supplementary heating
On the 2-3 seats model, this is located under
t he seat on the driver's side with air diffusion
directed forwards.
On the 5 -9
seats model, it is
located at the rear. Depending
on the model, the air diffusion
is either direct from the rear
or comes from the rail located
under each of the two rows of
seats.
F

P
ress this control to activate/
deactivate the heating. The
LED comes on if the heating is
activated.
When rapid demisting and defrosting is
required, switch off the control.
Rear heating and/or air
conditioning
If your vehicle is fitted with an additional air
conditioning unit, located in the rear of the
vehicle: the distribution rail located in the
roof and the individual diffusion vents provide
a
per fect diffusion of cold air.
Ease of use and comfort

47
The warm air diffused at floor level from the
front air conditioning unit is distributed at the
feet of the rear passengers of rows 2 and 3.
A warm air diffusion vent, located on the rear
left wheel arch, can supplement the unit for the
feet of the rear passengers in row 3.
Activation/Deactivation
F From the driver's seat, press this button on the MODE control
panel to activate the operation
of the rear controls. The
indicator lamp comes on.
Air flow
F Turn the control to your chosen position to obtain sufficient air
flow for your comfort.
Comfort temperature
adjustment
F Turn the control to select a position between blue
(cold) and red (hot) so as to
adjust the temperature to your
requirements.
The OFF control on the "Single zone"
central control panel switches off the
function.
However, a safety device will ventilate the
rear circuit automatically, even if the control
is in position 0, to prevent condensation
forming.
Pressing this button again deactivates the rear
controls. The indicator lamp goes out.
Programmable additional
heating
This also facilitates passenger
compartment heating, demisting and
defrosting.
Digital programming
control
The programmable heating control panel is
located to the side of the steering wheel below
the MODE control panel.
Time display
Heating cycle indicator
Time setting and reading indicator
If your vehicle is fitted with separate
programmable heating, it gradually brings the
engine up to a

By default, pre-selected times are already
stored in the system (1 = 06:00; 2 = 16:00;
3 = 22:00). Any modification cancels and
replaces the previous pre-selected time.
If the battery is disconnected, the default
pre-selected times are restored.

Ease of use and comfort

50
To avoid the risks of poisoning or
asphyxia, the additional heating must
not be used, even for short periods, in
a closed environment such as a garage or
workshop which are not equipped with an
exhaust gas extraction system.
The additional heating switches off when
the battery voltage is low, so as to allow
engine starting.
The additional heating is fed by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when refuelling to avoid any risk of fire or
explosion!
The temperature near the heating
system must not exceed 120°C. A higher
temperature (e.g. when baking the
paint) could damage the components of
electronic circuits.
The additional heating is fitted with
a
temperature limiter which cuts off
the combustion in the event of engine
overheating due to a
lack of coolant.
Check the level and top up if necessary.
For more information on Checking levels ,
refer to the corresponding section.
Then press the programme selection
button before switching the heating on
again.Recommendations for ventilation and air conditioning
In order for these systems to be fully effective,
follow the operation and maintenance
guidelines below:
F

T
o ensure that the air is distributed evenly,
keep the external air intake grilles at the
base of the windscreen, the nozzles, the
vents, the air outlets and the air extractor
in the boot free from obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used for
regulation of the automatic air conditioning
system.
F

O
perate the air conditioning system for
at least 5
to 10 minutes once or twice
a
month to keep it in per fect working order.
F

E
nsure that the passenger compartment
filter is in good condition and replace
the filter elements periodically. We
recommend the use of a
combined
passenger compartment filter. Thanks to
its special active additive, it helps both to
purify the air breathed by the occupants
and to keep the passenger compartment
clean (reduction of allergic symptoms, bad
odours and greasy deposits). F
T o 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.
F

I
f the system does not produce cold air,
switch it off and contact a
CITROËN
dealer or a
qualified 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.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d
o not drive for too long with the
ventilation switched off.
-

d
o not keep air recirculation set for an
extended period.
