Refuel without delay.
The calculation of the remaining fuel depends on
the style of driving, the profile of the road, the time
elapsed and the distance travelled since the lamp first
came on.

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.

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.
Topping up with AdBlue®
Before topping up, please read the
following warnings carefully.
Precautions for use
AdBlue® is a urea-based solution. This fluid
is
non-flammable, colourless and odourless
(stored in a
cool place).
In the event of contact with the skin, wash the
affected area with soap and running water. In
the event of contact with the eyes, immediately
rinse the eyes with large amounts of water
or with an eye wash solution for at least
15

minutes. If a burning sensation or irritation
persists, get medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high exterior temperature,
for example), the risk of ammonia being
released cannot be excluded: do not inhale
the vapours. Ammonia has an irritant effect on
mucous membranes (eyes, nose and throat).
AdBlue® (BlueHDi
engines)
To respect the environment and ensure
compliance with the Euro 6
standard, without
adversely affecting the per formance or fuel
consumption of 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® containing urea, a
catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment.
The AdBlue
® is contained in a special tank with
a
capacity of approximately 14 litres.
It has an exterior filler located behind the fuel
filler flap below the fuel filler cap and closed
with a

blue filler cap .
An alarm system is triggered once the
remaining range is 1,500 (2,400 km), in other
words once the reser ve level is reached. Once the AdBlue
® tank is empty, a
regulatory device prevents the engine
from being restarted.
If the SCR system is faulty, the level of
emissions from your vehicle no longer
meet the Euro 6

regulations: 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: having travelled 250 miles
(400 km), a device will be triggered
automatically to prevent the engine from
starting.
