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 HEAtI n G A nd / O r AI r
c O nd I t IO n I n G
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 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.

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.

Keep AdBlue
® out of the reach of
children, in its original container.
Never transfer AdBlue
® to another container:
it would loose its purity.
Never dilute the fluid with water.
Never pour the fluid into the Diesel fuel tank.
recommendations on storage
Never store containers or bottles of
AdBlue® in your vehicle.
Freezing of the AdBlue
®
The SCR system includes an AdBlue®
tank heater that ensures operation of
the vehicle in normal conditions.
In exceptional situations, such as when the
vehicle is kept at temperatures below -15°C
(5°F) for a long period, there may be an
emission fault alert related to freezing of the
AdBlue
® additive.
Park the vehicle in an area at a more
moderate temperature for a few hours until
the AdBlue
® becomes a fluid again.
The emissions warning lamp does not go off
immediately, but does so after a few miles
of driving.
Never dispose of AdBlue® fluid bottles
in the household waste.
Place them in a special container provided
this purpose or take them to your dealer.
AdBlue® freezes at about -11°C
(12.2° F) and deteriorates above 25°C
(77°F).
It is recommended that containers and
bottles be stored in a cool area and
protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a year.
Additive that has been frozen can be used
once it has thawed out in ambient air.
