Particle filter (Diesel)
- fixed illumination of the particle f
ilter warning lamp, accompanied
b
y an audible signal and a
m
essage that there is a risk of
b
lockage of the particle filter.
The presence of this label, in particular with
the
Stop
&
Start
system,
indicates
the
use
of
a s
pecific 12 V lead-acid battery with special
technology
and
specification.

CITROËN
dealer
or

s
essential
when
replacing
or
disconnecting
t
he
battery. As
soon
as the traffic conditions permit,
r
egenerate the filter by driving at a speed of at
l
east
40
mph (60 km/h) until the warning lamp
g
oes
off.
If
the
warning lamp stays on, refer to the
"
Additive
level" section.
Unless
other wise
indicated,
check
these
components
in
accordance
with
the
manufacturer's
service
schedule
and according to your engine.
Other wise,
have
them
checked
by
a
CITROËN
dealer
or
a
qualified
workshop.
Air filter and passenger compartment filter
Refer to the manufacturer's s
ervice schedule for details of the
replacement
intervals for these
c
omponents.
Oil filter
Replace the oil filter each time the e ngine oil is changed.
Refer
to the manufacturer's
s
ervice schedule for details of
the
replacement interval for this

12 V battery
The battery does not require any maintenance.
H owever, check that the terminals are clean a
nd correctly tightened, particularly in summer
a
nd winter.
When carrying out work on the battery, refer to the "12 V battery" section for details of the
precautions
to be taken before disconnecting
t
he battery and following its reconnection.Depending
on the environment (e.g. dusty a
tmosphere) and the use of the vehicle
(e.g.
city driving), replace them twice as often
if necessary .
A
clogged passenger compartment filter may
h
ave an adverse effect on the per formance
o
f the air conditioning system and generate
u
ndesirable
o
dours.The start of saturation of the particle filter is
indicated
by:
on a n
ew vehicle, the first operations of
regeneration
of the particle filter may be
a
ccompanied by the smell of "burning",
w
hich is per fectly normal.
Following
prolonged operation of the
v
ehicle at very low speed or at idle,
you
may, in exceptional circumstances,
n
otice the emission of water vapour at
t
he exhaust on acceleration. This does
n
ot affect the behaviour of the vehicle
or
the environment.

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)
w
ith 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.
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
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 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: you
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
running
distance of 650 miles
(
1 100
km),
a
system will be triggered
a
utomatically
to
prevent engine starting.

Filling
the
AdBlue

ncluded in every routine service on your
vehicle
by
a
CITROËN dealer or a qualified

Nevertheless,
given the capacity of the tank,

more particularly if an alert

If
you
envisage
topping-up yourself, please
r
ead
the
following
warnings carefully. The
a d
blu

solution.
This liquid is non-flammable,
c
olourless
and odourless (kept in a cool area).
In

event
of contact with the skin, wash
t

If
swallowed, immediately wash out the mouth

In
certain
conditions (high ambient
