ADDITIONAL HEATING SYSTEMS
Supplementary heating
On the 2-3 seats version, this is located
under the seat on the driver ’s side with air
diffusion directed forwards.
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 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 an additional passenger compartment
heating system which supplements the
standard equipment.
It can operate independently of the engine.
Depending on the level of finish of the
equipment, its start-up can be programmed.
Additional heater or programmable heating
This is an additional and autonomous
system which heats the diesel engine hot
coolant loop to make starting easier.
It improves the de-icing and demisting
performance and that of the heated seats, if
fitted in 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 diode
is lit if the heating is activated.
When rapid de-icing and
demisting is required, switch off the control.

Activation/Deactivation
This control, located on the
control pad at the right-hand
end of the fascia, enables you to
activate/deactivate the operation
of the rear controls from the driver ’s seat.
The first press activates (diode lit).
A second press deactivates (diode 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.
Air flow
The force of the blown air, via
the vents, varies from 1 to the
strongest 4.
To obtain a comfortable level of
ambient air, remember to adjust this control.
Comfort value adjustment
- on the blue, triggers cool air,
- on the red, triggers heating of the ambient air.
The OFF control on the "Mono-zone" central
control panel switches the function off.

PROGRAMMABLE ADDITIONAL HEATING
If your vehicle is fitted with autonomous
programmable heating: it gradually brings
the engine up to a good temperature to
facilitate starting. An integrated clock permits programming of
its start time. The passenger compartment
will be heated more quickly. Heating cycle indicator light

Setting the time of the internal clock
Set the clock on the control panel before
programming the deferred switching on of
the heating.
Immediate switching on of the 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. This symbol or the previous stored time
and the number (e.g. 1) corresponding to
the recalled pre-selection are displayed for
ten seconds.

Note: if you wish to recall the other
pre-selected times, press the SET button
several times before the ten seconds have
elapsed.
Press this button.
The display and the associated
indicator light come on.
Within ten seconds, press these two setting
buttons until the correct time is displayed.
Press ">" to increase the hours or
"<" to decrease.
Press and hold the button for
more rapid scrolling of the digits.
Reading the time
Press this button.
This indicator light comes
on, the time is displayed for
approximately ten seconds. Press this button.
The display and the heating
cycle indicator light come on
and remain on throughout the
duration of operation.
Switching on the 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.

Note
: if you wish to start the heating at a
fixed time each day, simply reprogramme
the stored time each day.
Press this button, the display
becomes overbright. Within the ten seconds, press
these two setting buttons to
select the required start time.
Setting of the stored time is
confi rmed by clearing of the start
time, displaying of the pre-selection
number (e.g. 1) and overbrightness
of the display lighting.

Ventilation
Cancelling the programming
Press this button briefly to clear
the programmed start time. The display lighting and the
pre-selection number (e.g. 1) are
switched off.
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 is supplied by the
vehicle's fuel tank.
Ensure that the fuel gauge indicator light is
not at reserve.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire.
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 system is fitted with
a temperature limiter which cuts off the
combustion in the event of overheating due
to a lack of coolant.
Top up the coolant, then press the
programme selection control before
switching the heating on again. Have the additional heating system
checked at least once a year at the
beginning of winter. Maintenance and
repairs should only be carried out by a
CITROËN dealer.
Use recommended replacement parts only.
Recalling one of the pre-selected start times
Press this button as many times
as necessary until the number
corresponding to the required
pre-selected start time (e.g. 2)
appears.
After ten seconds, the time is cleared but
remains stored for as long as the number
(e.g. 2) and the display remain lit.
Switching off the heating
Press this button.
The heating cycle indicator light
and the display are switched off.
Two different types of equipment
The additional heating is autonomous 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, de-icing and demisting.
The additional passenger compartment
heating system supplements the
standard equipment. Its operation may be
independent of the engine.
Switching on of the heating may be
programmable.
