AdBlue® additive and SCR system
f
or
BlueHDi 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 system
Using an additive called AdBlue® containing urea, a
catalytic
converter
turns
up
to
85% of nitrous o
xides
(NOx)
into
nitrogen
and
water, which are
h
armless
to
health
and
the
environment. Once the AdBlue
® tank is empty, a s
ystem
required
by regulations prevents
s
tarting
of
the
engine.
If the SCR is faulty, the level of
emissions
from
your vehicle will no
l
onger
meet
the
Euro 6 standard: your
v
ehicle
becomes
polluting.
In
the
event
of
a
confirmed fault
w
ith
the
SCR
system, you must go
t
o
a
CITROËN
dealer or a qualified
w
orkshop
as
soon as possible: after a
r
unning
distance
of 650 miles
(1
100
km),
a
system will be triggered
a
utomatically
to
prevent engine starting.
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.
