Group of supplementary systems which help you   to   obtain   optimum   braking   in   complete  
s

afety   in   emergency   situations:
-
 
a
nti-lock   braking   system   (ABS),
-
 
e
lectronic   brake   force   distribution   (EBFD),
-
 
e
mergency   braking   assistance   (EBA).
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and manoeuvrability   of   your   vehicle   when   braking,   in p

articular   on   poor   or   slippery   sur faces.
Activation
The anti-lock braking system comes into operation   automatically   when   there   is   a   risk   of  
w

heel   lock.
Normal
  operation   of   the   ABS   may   make   itself  
f

elt   by   slight   vibration   of   the   brake   pedal.
Operating fault
If this warning lamp comes on, accompanied   by   an   audible   signal  
a

nd   a   message   in   the   screen,   it  
i

ndicates   a   malfunction   of   the   anti-
lock
  braking   system   which   could  
r

esult in loss of control of the vehicle
when
 b

raking.
If
  this   warning   lamp   comes   on,
 t

ogether   with   the   STOP and ABS
warning
  lamps,   accompanied   by   an
 a

udible   signal   and   a   message   in   the
 s

creen,   it   indicates   a   malfunction   of
 t

he   electronic   brake   force   distribution
 w

hich could result in loss of control of
the
  vehicle   when   braking.
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
resistance of the pedal and an increase in
braking
 e

fficiency.
You must stop as soon as it is safe to do so.
In either case, contact a CITR
oËn

dealer or a
qualified
 w

orkshop.
When
 
braking
 
in
 
an
 
emergency,
 
press
 
v

ery
 
firmly
 
without
 
releasing
 
the
 
p

ressure. When
  braking   in   an   emergency,   press  
f

irmly   without   releasing   the   pressure.
When
 
replacing
 
wheels
 
(tyres
 
and
 
r

ims),
 
ensure
 
that
 
they
 
conform
 
to
 
the
 
ma

nufacturer's
 r

ecommendations.

Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (DSC)
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

Deactivation
In extremely severe conditions (deep snow, mud,   ...),   if   you   are   unable   to   move   off,   it   may  
b

e   useful   to   temporarily   deactivate   these  
s

ystems   so   that   the   wheels   can   spin   freely   and

The driver must ensure that passengers use the seat belts correctly and that they are all
restrained
  securely   before   setting   off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
Do
  not   interchange   the   seat   belt   buckles   as  
t

hey   will   not   fulfil   their   role   fully.
The seat belts are fitted with an inertia reel
permitting
  automatic   adjustment   of   the   length  
o

f   the   strap   to   your   size.   The   seat   belt   is  
s

towed   automatically   when   not   in   use.
be

fore and after use, ensure that the seat belt
is
  reeled   in   correctly.
The
  lower   part   of   the   strap   must   be   positioned  
a

s   low   as   possible   on   the   pelvis.
The
  upper   part   must   be   positioned   in   the  
h

ollow   of   the   shoulder.
The
  inertia   reels   are   fitted   with   an   automatic
 l

ocking   device   which   comes   into   operation   in
 t

he   event   of   a   collision,   emergency   braking
 o

r   if   the   vehicle   rolls   over.   You   can   release
 t

he   device   by   pulling   the   strap   firmly   and   then
 r

eleasing   it   so   that   it   reels   in   slightly.In
  order   to   be   effective,   a   seat   belt   must:
-  b e   tightened   as   close   to   the   body   as  
p

ossible,
-
 
b
e   pulled   in   front   of   you   with   a   smooth  
m

ovement,   checking   that   it   does   not  
t

wist,
-
be

used to restrain only one person,
-

ot   bear   any   trace   of   cuts   or   fraying,
-
 
n
ot   be   converted   or   modified   to   avoid

In accordance with current safety
regulations,
  for   all   repairs   on   your   vehicle's  
s

eat   belts,   go   to   a   qualified   workshop   with  
t

he   skills   and   equipment   needed,   which   a  
C

ITROËN   dealer   is   able   to   provide.
Have
  your   seat   belts   checked   regularly   by  
a

  CITROËN   dealer   or   a   qualified   workshop,  
p

articularly   if   the   straps   show   signs   of  
d

amage.
Clean the seat belt straps with soapy
water
  or   a   textile   cleaning   product,   sold   by  
C

ITROËN   dealers.
After
  folding   or   moving   a   seat   or   rear   bench  
s

eat, ensure that the seat belt is positioned
and
  reeled   in   correctly.Recommendations for children
Use a suitable child seat if the passenger is less than 12 years old or shorter than one
and
  a   half   metres.
Never
  use   the   same   seat   belt   to   secure   more  
t

han   one   person.
Never
  allow   a   child   to   travel   on   your   lap.
For
  more   information,   refer   to   the   "Child

 se
ction.
In the event of an impact
Depending on the nature and seriousness
of the impact ,
  the   pretensioning   device   may  
b

e deployed before and independently of the
airbags.
  Deployment   of   the   pretensioners  
i

s   accompanied   by   a   slight   discharge   of  
h

armless   smoke   and   a   noise,   due   to   the  
a

ctivation   of   the   pyrotechnic   cartridge  
i

ncorporated   in   the   system.
In
  all   cases,   the   airbag   warning   lamp  
comes
  on.
Following
  an   impact,   have   the   seat   belts
