If you are filling your tank to the top, do
not persist after the 3rd cut- off; this could
cause malfunctions.
A
  label   on   the   inside   of   the   fuel   filler   flap  
r

eminds   you   of   the   type   of   fuel   to   use,  
d

epending   on   your   engine   type.
Additions
  of   fuel   must   be   of   at   least   5   litres   to  
b

e   registered   by   the   fuel   gauge.
When
 
it
 
first   comes   on,   about 6 litres of fuel
remain
 
in
 
the   tank.
Until
 
sufficient   fuel   has   been   added,   this  
w

arning
 
lamp   appears   every   time   the   ignition  
i

s
 
switched   on,   accompanied   by   an   audible  
w

arning
 
and   a   message.   This   audible   warning  
a

nd
 
message   are   repeated   with   increasing  
f

requency
  as   the   fuel   level   drops   towards   "0 ".
Refuel
 
as
  soon   as   possible   to   avoid   running  
o

ut. Opening
  the   filler   flap   may   result   in   an   inrush   of  
a

With Stop & Start, never refuel with the
system
  in   STOP   mode;   you   must   switch

the   ignition   with   the   START/STOP  
b

utton.
Checks

305
The petrol or Diesel engine of your vehicle is fitted   with   a   catalytic   converter,   a   device   which  
h

elps   to   reduce   the   level   of   harmful   emissions  
i

n   the   exhaust   gases.
For petrol engines, you must use unleaded
fuel.
The
  filler   neck   is   narrower,   allowing   only  
u

nleaded   petrol   nozzles   to   be   introduced.
If you have put in the wrong fuel
for your vehicle, you must have the
fuel tank drained and filled with
the correct fuel before star ting the
engine.
Fuel cut- of f
Your vehicle is equipped with a safety device w hich cuts off the fuel supply in the event of a
collision.
Misfuel prevention (Diesel)*
Operation
When a petrol filler nozzle is introduced into the f uel   filler   neck   of   your   Diesel   vehicle,   it   comes  
i

nto   contact   with   the   flap.   The   system   remains  
c

losed   and   prevents   filling.
Do not persist but introduce a Diesel type
filler nozzle. Mechanical   device   which   prevents   filling   the   tank   of   a   Diesel   vehicle   with   petrol.   It   avoids   the   risk   of  
e

ngine   damage   that   can   result   from   filling   with   the   wrong   fuel.
It   remains   possible   to   use   a   fuel   can   to  
f

ill   the   tank.
In   order   to   ensure   a   good   flow   of   fuel,  
d

o   not   place   the   nozzle   of   the   fuel   can  
i

n   direct   contact   with   the   flap   of   the  
m

isfuel   prevention   device   and   pour  
s

l ow l y.
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   your  
v

ehicle   is   suitable   for   the   fuel   pumps   in  
t

he   country   in   which   you   want   to   travel.
