Fuel used for petrol engines
The petrol engines are compatible with E10   bio-petrol   (containing   10   %   ethanol),  
c

onforming   to   European   standards   EN   228   and  
E

N
 1
5376.
E85
  type   fuels   (containing   up   to   85   %   ethanol)  
a

re   reserved   exclusively   for   vehicles   marketed  
f

or   the   use   of   this   type   of   fuel   (BioFlex  
v

ehicles).   The   quality   of   the   ethanol   must  
c

omply   with   European   standard   EN   15293.
Fuel used for diesel
engines
The Diesel engines are compatible with b
iofuels   which   conform   to   current   and   future  
E

uropean   standards   (Diesel   fuel   which  
c

omplies   with   standard   EN   590   mixed   with  
a

  biofuel   which   complies   with   standard  
E

N 14214)   available   at   the   pumps   (containing  
u

p   to   7   %   Fatty   Acid   Methyl   Ester).
B30
  biofuel   can   be   used   in   certain   Diesel  
e

ngines.   However,   this   use,   even   occasional,  
r

equires   strict   application   of   the   special  
s

ervicing   conditions.   Contact   a   CITROËN  
d

ealer   or   a   qualified   workshop.
The
  use   of   any   other   type   of   (bio)fuel  
(

vegetable   or   animal   oils,   pure   or   diluted,  
d

omestic   fuel...)   is   strictly   prohibited   (risk   of  
d

amage   to   the   engine   and   fuel   system).
For
 
the

we
 
strongly
 
r

ecommend
 
the
 
use
 
of

to
 
ensure
 
optimum

* According to country of sale.
Misfuel prevention (Diesel)*Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the wrong   fuel.
Located
  in   the   filler   neck,   the   misfuel   prevention   device   appears   when   the   filler   cap   is   removed.
Operation
When a petrol filler nozzle is introduced into the fuel   filler   neck   of   your   Diesel   vehicle,   it   comes  
i

nto   contact   with   the   flap.   The   system   remains  
c

losed   and   prevents   filling.

Travelling abroad
As Diesel fuel pump nozzles may b
e   different   in   other   countries,   the  
p

resence   of   the   misfuel   prevention  
d

evice   may   make   refuelling   impossible.
Before
  travelling   abroad,   we  
r

ecommend   that   you   check   with   the  
C

ITROËN   dealer   network,   whether  
y

our vehicle is suitable for the fuel
pumps
  in   the   country   in   which   you   want  
t

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 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
  AdBlue
® additive is held in a special t
ank
 
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
 
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
 
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  
s

tarting.

Range indicators
Once the AdBlue® tank is on reserve or after d
etection
 
of
 
a
 
fault   with   the   SCR   emissions  
c

ontrol
 
system,
 
when   the   ignition   is   switched  
o

n,
 
an
 
indicator
 
displays   an   estimate   of   the  
d

istance
 
that
 
can
 
be   covered,   the   range,   before  
e

ngine
 
starting
 
is
 
prevented.
In
 
the
 
event
 
of
 
simultaneous   system   fault   and  
l

ow
 
AdBlue
® level, the shortest range figure is t
he
 
one
 
displayed. The
  engine   start   prevention   system  
r

equired   by   regulations   is   activated  
a

utomatically   once   the   AdBlue
® tank i
s
 
empty.
In the event of the risk of non-starting related to a lack of AdBlue®
Range greater than 1 500 miles (2 400 km)
When   the   ignition   is   switched   on,   no  
i

nformation   on   range   is   displayed   automatically  
i

n   the   instrument   panel.
Remaining range between 350 and 1500 miles (600 and 2 400 km)
When switching on the ignition, the UREA warning   lamp   comes   on,   accompanied  
b

y   an   audible   signal   and   the   display   of   a  
m

essage   (e.g.:   "Top   up   emissions   additive:  
S

tarting   prevented   in   900   miles")   indicating  
t

he   remaining   range   expressed   in   miles   or  
k

ilometres.
When
  driving,   the   message   is   displayed   every  
2

00   miles   (300   km)   until   the   additive   tank   has  
be

en
 t
opped-up.
Go
  to   a   CITROËN   dealer   or   a   qualified

a

  CITROËN   dealer   or   a   qualified  
w

orkshop   for   the   top-up   required.   If  
y

ou   carry   out   the   top-up   yourself,   it   is

In the event of a fault with the the SCR emissions control system
If it is a temporary fault, the alert disappears   during   the   next   journey,  
a

fter   self-diagnosis   of   the   SCR   system.
A
  system   that   prevents   engine   starting   is   activated   automatically   from   650   miles   (1   100   km)   after   confirmation   of   a   fault   with   the   SCR   emissions  
c

ontrol   system.   Have   the   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop   as   soon   as   possible.
In the event of the detection of a fault
du
ring an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
The
 
UREA,   SERVICE   and   diagnostic   warning  
l

amps
  comes   on,   accompanied   by   an   audible  
s

ignal
  and   the   display   of   the   message  
"

 f
ault".
The
 
alert   is   triggered   when   driving   when   the  
f

ault
 
is   detected   for   the   first   time,   then   when  
s

witching   on   the   ignition   for   subsequent  
j

ourneys,   while   the   fault   persists. If   a   fault   with   the   SCR   system   is   confirmed   (after
 3

0   miles   (50   km)   covered   with   the   permanent
 d

isplay   of   the   message   signalling   a   fault),   the

 r

emaining   range   express   in   miles   or   kilometres.
While   driving,   the   message   is   displayed   every
 3

0   seconds   while   the   fault   with   the   SCR   system
 p
ersists.
The   alert   is   repeated   when   switching   on   the ig

nition.
You
  should   go   to   a   CITROËN   dealer   or   a
 q

ualified   workshop   as   soon   as   possible.
Other wise, you will not be able to restart your
engine. You
  have   exceeded   the   authorised  
d

riving   limit:   the   starting   prevention  
s

ystem   inhibits   engine   starting.
Every 
time  the  ignition  is  switched  on,  the  SERVICE a

Starting prevented
To
