adblue® additive and SCR system
f
or
Blue
HDi Diesel engines
To assure respect for the environment and c
onformity with the new Euro 6 emissions
s
tandard, without adversely affecting the
p
er formance or fuel consumption of Diesel
e
ngines, CITROËN has taken the decision to
e
quip its vehicles with an effective system that
a
ssociates SCR (Selective Catalytic Reduction)
with
a particle filter (FAP) for the treatment of
e
xhaust gases.
Presentation of the ScR s ystem
Using an additive called AdBlue® containing u
rea, a catalytic converter turns up to
85% of
nitrous
oxides
(NOx)
into
nitrogen
a
nd
water,
which
are
harmless
to health and
t
he environment. The
a d
blu
e
® 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
a
d
blu
e
® 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.
on
ce the a
dbl
ue
® tank is empty, a
system
required
by regulations
p
revents
starting
of the engine.
If the SCR
is faulty, the level of
emissions
from
your vehicle will no
l
onger
meet
the
Euro 6 standard: you
v
ehicle
becomes
polluting.
In
the
event
of
a
confirmed fault
w
ith
the
SCR
system, you must go
t
o a CITR
oË
N 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
s
tarting.

keep a dblu e® out of the reach of
children,
in
its
original bottle.
Never transfer
a d
blu
e
® to another
container:
it
would
loose its purity. Never
dilute the additive with water.
Never pour the additive into the Diesel
fuel tank.
Never top-up from an AdBlue®
dispenser
reserved
for
heavy
goods
v
ehicles.
Filling
the
AdBlue
® tank is an operation i
ncluded in every routine service on your
vehicle by a CITR
oË
N dealer or a qualified
workshop.
Nevertheless,
given the capacity of the tank,
i
t
may
be
necessary to top-up the additive
b
etween
services,
more particularly if an alert
(
warning
lamps
and a message) signals the
r
equirement.
You
can
got
to
a
CITROËN dealer or a qualified
w
orkshop.
If
you
envisage
topping-up yourself, please
r
ead
the
following
warnings carefully.
Topping-up the AdBlue® additive
Precautions in use
Use only adblu e® additive that meets the I
SO 22241
standard.
The
supply
in
a
non-drip bottle simplifies
t
oping-up.
You
can obtain 1.89 litre (half a US
g
allon)
bottles
from a CITROËN dealer or a
q
ualified
w
orkshop.
The
a
dblu
e® additive is an urea-based
solution.
This liquid is non-flammable,
c
olourless
and odourless (kept in 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
w
ith
clean
water and then drink plenty of water.
In
certain
conditions (high ambient
t
emperature,
for example), the risk of release
o
f
ammonia
cannot be excluded: do not inhale
t
he
product.
Ammonia vapour has en irritant
e
ffect
on
mucous membranes (eyes, nose and
t
hroat).
