The settings range between:
-

increasing the interior ambient air

temperature HI (High) which goes up to
to a maximum setting of 32,
-

cooling the interior ambient air

temperature LO (Low) which goes down
to a setting of 16.
Air distribution
A press illuminates the LED on the buttons
which distribute the air flow towards:
the windscreen and front side
window vents (demisting/
defrosting the windows),
the central and side vents (chest
and face),
the vents in the front and rear
areas (feet).
The combination of buttons permits
improvement of air distribution.
Air flow
Successive presses of this button
increase (+) or reduce (-) the
force of the air flow to the interior.
Intake of exterior air / r ecirculation of interior air
When the LED is on, the air
recirculates inside the passenger
compartment to prevent the entry of exterior
odours and smoke. This position should be
temporary.
When the ambient air comfort level has been
reached, pressing the button switches the
LED off and reopens the exterior air intake.
Pressing the A

O
button also restores
the intake of exterior air. Returning to this
position permits renewal of the air in the
passenger compartment and demisting.
Pressing the A

function.
rapid demisting / defrosting
Pressing this control permits
rapid clearing of the windows.
The LED is on.
The system manages the air conditioning,
the flow and intake of air, the defrosting
of the rear screen and provides optimum
distribution of the air to the windscreen and
front side windows.
If your vehicle is fitted with additional
heating, switch it off to ensure rapid and
effective demisting/defrosting.

If your vehicle is fitted with an additional
air conditioning unit, located in the rear of
the vehicle: the distribution duct located in
the roof and the individual diffusion vents
provide a perfect diffusion of cold air.
The warm air diffused at the floor, 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 wheelarch, may complete the assembly
for the feet of the rear passengers of row 3.
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
performance and that of the heated seats, if
fitted to the vehicle.
The passenger compartment heating is
brought up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle. On the 5-9 seats version, it is
located at the rear. Depending
on the model version, the air
diffusion is either direct from the
rear or comes from the rail located under
each of the two rows of seats.
Press this control to activate/
deactivate the heating. The LED
is on if the heating is activated.
When rapid demisting and
defrosting is required, switch off the control.
Automatic additional heating
This is an additional system which starts
automatically when the ignition is switched
on. Its activation depends on the ambient
temperature and the temperature inside the
vehicle.
It switches off automatically once the
heating system is started manually.

Activation/deactivation
This control, located on the
control panel at the right-hand
end of the dashboard, enables
you to activate/deactivate the
operation of the rear controls from the
driver's seat.
The first press activates (LED on).
A second press deactivates (LED off). To deactivate the blower, place the control in
position 0.
However, a safety device will ventilate the
rear circuit automatically, even if the control
is in position 0, to prevent the formation of
condensation.

68Immediate heating
Before switching on the heating, check that:
-
the temperature setting control is in the

"Hot air" position (red),
-

the air flow setting control is in

position

"2"
. The
"- -:- -" symbol or the
previous stored time and the
number (1, 2 or 3) corresponding
to the recalled pre-selection are
displayed for ten seconds.
n

ote: if you wish to recall the other pre-
selected times, press the "set" button
repeatedly before the ten seconds have
elapsed.
Press this button.
The screen and the heating cycle
indicator come on and remain
on throughout the duration of
operation.
deferred heating
Switching on can be programmed between
one minute and twenty-four hours in
advance.
You can store up to three different start
times, but programme one deferred start
only.
n

ote: if you wish to start the heating at a
fixed time each day, simply reprogramme
the stored time each day.
Press the "set" button, the
screen comes on. Within ten seconds, press the "<"
or ">"
setting button to select the
required start time.
Setting of the stored time is confirmed by
clearing of the start time, displaying of
the pre-selection number (1, 2 or 3) and
illumination of the screen.
By default, pre-selected times are
already memorised in the system
(1
= 6 hours; 2 = 16 hours; 3 = 22 hours).
Any modification cancels and replaces the
previous pre-selected time.
If the battery is disconnected, the default
pre-selected times are restored.
cancelling the programming
Press the "set" button briefly to
clear the programmed start time.
The screen illumination and the


pre-selection number (1, 2 or 3)
go off.
recalling one of the pre-selected
start times
Press the "set" button as many
times as necessary until the
number corresponding to the
required pre-selected start time
(1, 2 or 3) appears.
After ten seconds, the time disappears but
remains stored while the corresponding
number (1, 2 or 3) and the screen
remain

on.

Have the additional heating checked at
least once a year at the beginning of
winter. Maintenance and repairs should only
be carried out by a CITROËN dealer or a
qualified workshop.
Use only genuine replacement parts.
Switching off the heating
In the case of deferred operation, the
heating stops at the end of the programmed
period.
Good practice
To avoid any risk of poisoning or
asphyxiation, the additional heating must
not be used, even for short periods, in
an enclosed space such as a garage or
workshop which is not fitted 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 supplied by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion. The temperature near the heater must not
exceed 120
°C. A temperature higher than
this (for example in the case of painting in
an oven) could damage the components of
the 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 if necessary top-up following
the advice given in the "Checks - Levels"
section. Then press the programme
selection button before switching the heating
on again.
Setting the operating
period
The period of operation can be set to
between 10 and 60 minutes.
Press and hold the "set" button.
At the same time press the "<"
or ">" button.
The time and the time setting
indicator come on.
Press and hold the "set" button again.
At the same time press the "<" or ">" button
again.
The programmed operating period is
displayed and the heating or ventilation
cycle indicator flashes.
Adjust the period by pressing the "<" or ">"
button.
The setting is confirmed by the period
disappearing from the screen or by pressing
the "set" button again In the case of immediate
operation, press this button again
to switch off manually.
The heating cycle indicator and
the screen go off.

70two additional uses
The additional heating is separate and
programmable. Before you enter the vehicle,
it gradually increases the temperature of the
engine to make starting easier. This also
facilitates passenger compartment heating,
demisting and defrosting.
Also, the additional passenger compartment
heating system supplements the standard
system. Its operation may be independent of
the engine. Switching on of the heating may
be programmable.
