Ease of use and comfort
Additional pre-heater or programmable additional
heating
This is an additional, programmable and
independent system that heats the hot water
loop of the Diesel engine to facilitate starting.
It improves the performance of the defrosting
and demisting and, if fitted to the vehicle, that of
the heated seats.
The passenger compartment’s temperature rises
more quickly.
This system must be programmed to be started
before entering the vehicle.
Automatic additional heating
This is an additional system that starts
automatically when the ignition is switched on. Its
activation depends on the outside temperature
and the temperature inside the vehicle.
It switches off automatically as soon as the
heating is manually switched on.
Supplementary heating
On 2-3 seat versions, it is located under the
driver's seat with air diffusion directed towards
the front.
Complete switch-off
► Press button 3 to switch off the system. The
LED and the display go out.
Temperature
The scale is between:
– a rise in interior air temperature HI (High),
which heats up to a maximum graduation of 32,
– a cooling of interior air temperature LO (Low),
which decreases to a graduation of 16.
Air distribution
► Press one of the buttons 4 to direct the air
flow towards:
the windscreen and front side window
vents (demisting - defrosting windows),
the central and side vents (chest and
face),
the diffusers of the front and rear zones
(footwells).
Combining buttons makes it possible to refine
the air distribution.
Air flow
► Press one of the buttons 5 to increase or
decrease the air flow.
Air intake/Air recirculation
The intake of exterior air prevents the formation
of mist on the windscreen and side windows.
Recirculating the interior air isolates the
passenger compartment from exterior odours
and fumes.
This function allows hot or cold air to be delivered selectively and more quickly.
Return to exterior air intake as soon as possible
to avoid deterioration of the air quality and the
formation of mist.
► Press button 6 to activate interior air
recirculation. The indicator lamp comes on.
Pressing this button again restores exterior air
intake. The indicator lamp goes off.
Pressing button 1 also restores exterior
air intake. Returning to this position
allows the air in the passenger compartment
to be renewed and demisting. Pressing button
1 again restores the FULL AUTO function.
Additional rear ventilation
This system is complementary
to the standard passenger
compartment ventilation
equipment.




Air output
► Press control 1 to activate/deactivate the
release of air to the exterior (confirmed by the
LED coming on/going out).
Air intake
► Press control 2 to activate/deactivate
the exterior air intake into the passenger
compartment (confirmed by the LED coming on/
going out).
Additional heating systems
Additional heating
This is heating for the passenger compartment
which is additional to the standard equipment.
Its operation may be independent of the engine.

Supplementary heating
On 2-3 seat versions, it is located under the
driver's seat with air diffusion directed towards
the front.
On 5-9 seat versions, it is
located at the rear. Depending
on the version of 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.
► Press this control to activate/
deactivate the heating. The LED lights up
if heating is activated.
When quickly defrosting and demisting, turn off
the control.
Rear heating and/or air
conditioning






If the vehicle is equipped with an additional
air conditioning unit, located at the rear of the
vehicle: the distribution rail located in the roof
and the individualised air vents ensure a perfect
diffusion of cold air.
The hot air diffused from the front air conditioning
unit to the floor is distributed at the height of the
rear passengers' feet in rows 2 and 3.
A hot air vent, located on the left-hand rear
wheel arch, may complement the system for the
rear passengers’ feet in row 3.
Activation/Deactivation
► From the driver's seat, press this
button located on the MODE control panel
to activate the operation of the rear controls. The
indicator lamp comes on.
Pressing again on this button deactivates the
operation of the rear controls. The indicator lamp
goes off.

AdBlue® (BlueHDi
engines)


To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel Particle Filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue
® is contained in a special tank
holding about 19 litres.
It has an external filler neck, located in the fuel
filler flap under the filler neck of the fuel tank,
closed by a blue cap.
Its capacity allows a driving range of
approximately 3,700 miles (6,000 km) ( which
may vary considerably depending on the
driving style and the type of vehicle).
An alert system is triggered when the remaining
range reaches 1,500 miles (2,400 km), i.e. once
the reserve level has been reached.
Once the AdBlue® tank is empty, a
system required by legislation prevents
starting of the engine.
If the SCR system is defective, the level of
emissions from your vehicle will no longer
meet the Euro 6 standard: your vehicle
becomes polluting.
In the event of a confirmed fault with the SCR
system, you must go to a CITROËN dealer
or a qualified workshop as soon as possible:
after travelling a distance of 250 miles (400
km), a system will be triggered automatically
to prevent engine starting.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue® tank, allowing you to continue driving
in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
For the correct operation of the SCR
system:
– Use only AdBlue
® fluid that meets the ISO
22241 standard.
– Never transfer AdBlue
® to another container
as it would lose its purity.
– Never dilute AdBlue
® with water.
It is possible to obtain AdBlue
® from a CITROËN
dealer or a qualified workshop.
You can also visit a service station equipped with AdBlue® pumps specially
designed for passenger vehicles.
Recommendations on storage
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
