AdBlue® additive 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
p
er formance or fuel consumption of Diesel
engines,
CITROËN has taken the decision to
e
quip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust
gases.
Presentation of the SCR system
Using a fluid called AdBlue® containing urea, a c
atalytic
converter
turns
up
to 85% of nitrogen
o
xides
(NOx)
into
nitrogen
and water, which are
h
armless
to
health
and
the
environment. The AdBlue
® additive is held in a special
tank
located
under the boot at the rear of
t
he
vehicle.
It has a capacity of 17 litres: this
p
rovides
a
driving range of about 12 500 miles
(
20
000
km),
after which an alert is triggered
w
arning
you
when the reserve remaining is
e
nough
for
just 1 500 miles (2 400 km).
During
each
scheduled service of your vehicle
b
y
a
CITROËN dealer or a qualified workshop,
t
he AdBlue
® additive tank is refilled in order to a
llow
normal operation of the SCR system.
If
the
estimated mileage between two services
i
s
greater
than 12 500 miles (20 000 km), we
r
ecommend
that you go to a CITROËN dealer
o
r
a
qualified workshop to have the necessary
t
op-up
carried out. Once the AdBlue
® tank is empty, a s
ystem
required
by regulations
p
revents
starting
of the engine.
If the SCR
is faulty, the level of
emissions from your vehicle will no
longer
meet
the
Euro 6 standard: you
v
ehicle
becomes
polluting.
In the event of a confirmed fault
with
the
SCR
system, you must go
t
o 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
a
utomatically
to
prevent engine starting.

Freezing of the AdBlue® additive
The AdBlue
® additive freezes at
temperatures below around -11°C.
The SCR system includes a heater
for the AdBlue
® tank, allowing you to c
ontinue
driving in very cold conditions.
Topping-up the AdBlue®
Filling the AdBlue® tank is an operation i
ncluded in every routine service on your
vehicle by a CITROËN dealer or a qualified
workshop.
Nevertheless,
given the capacity of the tank, it
m
ay be necessary to top-up the fluid between
services,
more
particularly if an alert (warning
l
amps
and
a
message) signals the requirement.
You
can
go
to
a
CITROËN dealer or a qualified
w
orkshop.
If
you
envisage
topping-up yourself, please
r
ead
the
following
warnings carefully.Precautions in use
Use only AdBlue® fluid that meets the
ISO 22241
standard.
AdBlue® is a urea-based solution. This liquid is n
on-flammable, colourless and odourless (kept
i
n
a
cool area).
In
the
event of contact with the skin, wash
t
he
affected area with soap and water. In the
e
vent
of
contact with the eyes, wash (irrigate)
t
he
eyes with large amounts of water or with
a
n
eye
wash solution for at least 15 minutes.
I
f
a
burning sensation or irritation persists, get
m
edical
attention.
If swallowed, immediately wash out the mouth
with
clean water and then drink plenty of water.
In
certain conditions (high ambient
t
emperature, for example), the risk of release of
a
mmonia cannot be excluded: do not inhale the
f
luid.
Ammonia vapour has an irritant effect on
m
ucous
membranes (eyes, nose and throat).The supply in a non-drip bottle simplifies
topping-up.
You can obtain 1.89 litre (half a US
g
allon) bottles from a CITROËN dealer or a
q
ualified
w
orkshop.
Never dilute AdBlue
® with water.
N
ever pour AdBlue® into the Diesel fuel
tank.
Never top-up from an AdBlue
®
dispenser
reserved
for
heavy
goods
v
ehicles.
Keep AdBlue
® out of the reach of
children,
in
its
original bottle.
Never transfer AdBlue
® to another
container:
it
would
lose
its purity.

Recommendations on storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. It is recommended
t
hat bottles be stored in a cool area and
protected
from direct sunlight.
Under
these conditions, the fluid can be kept
f
or
at
least a year.
If the additive has frozen, it can be used once it
has
completely thawed out.
Procedure
Before topping-up, ensure that the vehicle is parked on a flat and level sur face.
In wintry conditions, ensure that the
temperature
of the vehicle is above -11°C.
O
ther wise, by freezing, the AdBlue
® cannot
be
poured
into
its
tank.
Park
your
vehicle in a
w
armer area for a few hours to allow the top-up
to
be
carried
out.
