Emergency braking assistance
System which, in an emergency, enables you to   obtain   the   optimum   braking   pressure   more  
q

uickly,   thus   reducing   the   stopping   distance.
Activation
It is triggered by the speed at which the brake pedal   is   pressed.
The
  effect   of   this   is   a   reduction   in   the  
r

esistance   of   the   pedal   and   an   increase   in  
b

raking
 e
fficiency.
When
  braking   in   an   emergency,   press  
f

irmly   without   releasing   the   pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (
d
SC)
The anti-slip regulation (also known as traction control)   optimises   traction   to   prevent   skidding  
o

f   the   wheels,   by   acting   on   the   brakes   of   the  
d

riving   wheels   and   on   the   engine.
The electronic stability control acts on the
brake
  of   one   or   more   wheels   and   on   the   engine  
t

o   keep   the   vehicle   on   the   trajectory   required  
b

y   the   driver,   within   the   limits   of   the   laws   of  
p

hysics.Activation
These systems are activated automatically each   time   the   vehicle   is   started.
They
  come   into   operation   in   the   event   of   a   grip

  is   indicated   by   flashing   of   this

Safety

deactivation
In extremely severe conditions (deep snow, mud...),   when   it   is   not   possible   to   move   off,   it

ay   be   useful   to   temporarily   deactivate   the  
s

ystems,   so   that   the   wheels   can   spin   freely   and

Reactivation
These systems are reactivated automatically each   time   the   ignition   is   switched   back   on  
o

alfunction   of   these   systems.
Have
 
it   checked   by   a   CITROËN   dealer   or   a

Operation
When your vehicle is too close to or
approaches  the   vehicle   ahead   too   quickly   the  
s

ystem   automatically   applies   the   brakes   to  
a

void   a   collision.
The
  collision   can   be   avoided   automatically   if   the
 d

ifference   in   speed   between   your   vehicle   and   the
 v

ehicle   ahead   does   not   exceed   9   mph   (15   km/h).
Above
  this   threshold,   the   system   will   do   what
 i

s   possible   to   avoid   or   reduce   the   accident   by
 l

owering   the   speed   of   impact.
The
  automatic   braking   may   bring   the   vehicle   to  
a

  complete   stop   if   the   situation   requires   it.
In
  this   case,   the   vehicle   is   held   stationary  
t

emporarily   (for   about   1.5   seconds)   to   allow  
t

he   driver   to   take   back   control   by   pressing   the  
b

rake
 ped
al.
You
  are   then   alerted   by   the   display   of   a  
m

essage.
The
  brake   lamps   on   your   vehicle   come   on   to  
w

arn   other   road   users.
After
  an   impact,   the   system   is  
a

utomatically   put   out   of   service:   it   no  
lon

ger
 ope
rates.
You
  must   go   to   a   CITROËN   dealer   or   a  
q

ualified   workshop   to   have   the   system  
m

ade   operational   again.
During
  automatic   braking,   the   driver  
c

an   always   obtain   a   higher   rate   of  
d

eceleration   than   that   controlled   by   the  
s

ystem,   by   pressing   firmly   on   the   brake  
ped

al.
The
  triggering   of   the   system   may   cause  
t

he   engine   to   stall,   unless   the   driver  
d

epresses   the   clutch   pedal   quickly  
e

nough   during   automatic   braking.
deactivation
The system is deactivated in the vehicle configuration   menu,   accessible   with   the   ignition   on.
Its
  state   is   memorised   when   the   ignition   is
 s

witched off.
When the system is deactivated, a m essage   is   displayed   every   time   the  
i

gnition   is   switched   on,   to   warn   you.

Fuel tankFuel tank capacity: approximately 50 litres (petrol) or 46 litres (diesel);
(dep ending on version: approximately 30 litres (petrol or di esel)).
Low fuel level
Filling
A label affixed to the inside of the flap reminds you   of   the   type   of   fuel   to   be   used   depending   on  
y

our
 eng
ine.
Additions
  of   fuel   must   be   of   at   least   7   litres,   in  
o

rder   to   be   registered   by   the   fuel   gauge.The
  key   cannot   be   removed   from   the  
l

ock   until   the   cap   is   refitted.
Opening
  the   filler   cap   may   create   a  
n

oise   caused   by   an   inrush   of   air.   This  
v

acuum   is   entirely   normal,   resulting  
f

rom   the   sealing   of   the   fuel   system.
To
  fill   the   tank   safely:
F t he engine must be switched off,
F o pen the fuel filler flap,
F
 
i
nsert   the   key   in   the   cap,   then   turn   it   to  
t

he

left,F
 
r
emove   the   cap   and   hook   it   onto   the   clip  l
ocated   on   the   inside   of   the   flap,
F  f ill   the   tank,   but do not continue after the
3rd cut- off of the pump ;
  this   could   cause  
m

alfunctions.
When
  you   have   filled   the   tank:
F
 
p
ut   the   cap   back   in   place,
F
 
t
urn   the   key   to   the   right,   then   remove   it  
f

rom   the   cap,
F
 
c
lose   the   flap.
When the fuel tank minimum level is reached   this   warning   lamp   comes   on o

n   the   instrument   panel.   When   it   first
 c

omes   on   there   remains   approximately
5 litres
  of   fuel   in   the   tank.
With Stop & Start, never refuel with the
system  in   STOP   mode;   you   must   switch  
o

ff   the   ignition   with   the   key.
You
 
must   refuel   as   soon   as   possible   to   avoid  
r

unning   out   of   fuel.
If
 
you
 
run   out   of   fuel   (Diesel),   refer   also   to   the

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

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:   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

 
running
 
distance   of   650   miles  
(

1 100
 
km),
 
a
 
system   will   be   triggered  
a

utomatically
 
to
 
prevent   engine  
s

tarting.
