Once the AdBlue® tank is empty,
a s
ystem required by regulations
prevents starting of the engine.
If the SCR

system is faulty, 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
a running distance of 650 miles
(1

100 km), a system will be triggered
automatically to prevent engine
starting.
In either case, a range indicator gives
you the distance you can travel before
the vehicle is immobilised.
AdBlue® and SCR system
for BlueHDi Diesel engines
To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
per formance or fuel consumption of Diesel
engines, CITROËN has taken the decision to
equip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust gases.
SCR system
Using a fluid 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 held in a special tank with
a capacity of about 17 litres: this provides
a driving range of about 12 500 miles
(20

000

km). An alert is triggered automatically
to warn you when the reserve level is
reached: you can then drive about 1 500 miles
(2

400

km) before the tank is empty.
During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system.
If the estimated mileage of your vehicle
between two services is greater than
12

500

miles (20 000 km), it will be necessary
to top-up the AdBlue
®.

Practical information

255
Never store bottles of AdBlue® in your
vehicle.
Recommendations on storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. It is recommended
that 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 .
If the additive has frozen, it can be used once it
has completely thawed out. Before starting the top-up procedure, ensure
that the vehicle is parked on a flat and level
sur face.
Procedure
F Switch off the ignition and remove the
key, or if your vehicle has one, press the
START/STOP button to switch off the
engine.
F

AdBlue
® tank. S

Practical information

256
Never dispose of AdBlue® additive
bottles in the household waste. Place
them in a special container provided
this purpose or take them to your
dealer.
Important: if your vehicle's AdBlue
®
tank is completely empty - which
is confirmed by the alert displays
and the impossibility of starting the
engine

- you must add at least 3.8 litres
(so

two

1.89

litre bottles). If any additive is split or splashed, wash
immediately with cold water or wipe
with a damp cloth.
If the additive has crystallised, clean it
off using a sponge and hot water.
Important:
in the event of a top-
up after a breakdown because of
a lack of additive , you must wait
around 5 minutes before switching
on the ignition, without opening the
driver's door, locking the vehicle,
introducing the key into the ignition
switch, or introducing the key of the
"Keyless Entr y and Star ting" system
into the passenger compartment .
Switch on the ignition, then, after
10 seconds, start the engine.
