Lane departure warning system
Activation
Deactivation
DetectionOperating fault
System which detects the involuntary crossing o
f   longitudinal   traffic   lane   markings   on   the  
g

round   (solid   or   broken   line).
Sensors,
  fitted   below   the   front   bumper,   trigger  
a

  warning   if   the   vehicle   drifts   over   a   lane  
m

arking   (speed   higher   than   50   mph   (80   km/h)).
This
  system   is   particularly   useful   on   motor ways  
a

nd   main   roads. In
  the   event   of   a   malfunction,   the  
s

ervice   warning   lamp   comes   on,  
a

ccompanied   by   an   audible   signal  
a

nd   a   message   in   the   screen.
Contact   a   CITROËN   dealer   or   a   qualified  
w

orkshop.
The   lane   departure   warning   system  
c

annot   in   any   circumstances   replace  
t

he   need   for   vigilance   on   the   part   of   the  
d

river.
It
  is   necessary   to   observe   driving  
r

egulations   and   take   a   break   every  
t

wo hours. The
  detection   may   be   impeded:
- i f   the   sensors   are   dirty   (mud,   snow...),
-
 
i
f   the   markings   on   the   ground   are  
w

orn,
-

i
f there is little contrast between the
markings
  on   the   ground   and   the  
r

oad   sur face.
You
  are   warned   by   the   vibration   of   the   driver's  
s

eat   cushion:
-
 
o
n   the   right-hand   side,   if   the   marking   on  
t

he   ground   has   been   crossed   on   the   right,
-
 
o
n   the   left-hand   side,   if   the   marking   on   the  
g

round   has   been   crossed   on   the   left.
No
  warning   is   transmitted   while   the   direction  
i

ndicator   is   active   and   for   approximately  
2

0 seconds after the direction indicator is
switched
  off.
A
  warning   may   be   transmitted   if   a   direction  
m

(

e.g.   graffiti)   is   crossed.

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

onforming   to   European   standards   EN   228  
and
  EN   15376.
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 biofuels   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).
The
 
petrol
 
or
 
Diesel
 
engine
 
of
 
your
 
vehicle
 
is
 f
itted with a catalytic converter, a device which
helps
 
to
 
reduce
 
the
 
level
 
of
 
harmful
 
emissions
 
i

n
 
the
 
exhaust
 
gases.
For petrol engines, the use of unleaded fuel
is compulsory.
The
 
filler
 
neck
 
is
 
narrower,
 
admitting
 
unleaded
 
p

etrol
 
nozzles
 
only.
Fuel supply cut-off
Your vehicle is equipped with a safety device w hich cuts off the fuel supply in the event of a
collision. If you have put in the wrong fuel for
your vehicle, you must have the tank
drained and refilled with the correct
fuel before you star t the engine.

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.
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.
Do not persist but introduce a Diesel type
filler nozzle.
*
  Depending   on   the   country   of   sale.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
in direct contact with the flap of the
misfuel
  prevention   device   and   pour  
s

l ow l y.
Travelling abroad
As Diesel fuel pump nozzles may be different in other countries, the
presence
  of   the   misfuel   prevention  
d

evice   may   make   refuelling   impossible.
Not all Diesel vehicles are fitted with
misfuel
  protection,   so   before   travelling  
a

broad,   we   recommend   that   you   check  
w

ith   the   CITROËN   dealer   network,  
w

hether your vehicle is suitable for the
fuel
  pumps   in   the   country   in   which   you  
i

ntend   to   travel.
