Dynamic stability control (DSC)
and anti-slip regulation (ASR)The DSC system offers exceptional safety   in   normal   driving,   but   this   should  
n

ot   encourage   the   driver   to   take   extra  
r

isks   or   drive   at   high   speed.
The
  correct   operation   of   the   system  
d

epends on observation of the

t

he   braking   components,   the   electronic  
c

omponents   and   the   assembly   and  
r

epair procedures used by CITR
oËn

dealers.
After
  an   impact,   have   the   system  
c

hecked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
Activation
These systems are activated automatically each   time   the   vehicle   is   started.
As
  soon   as   they   detect   a   problem   of   grip   or  
t

rajectory,   these   systems   act   on   the   operation   if  
t

he   engine   and   brakes.
Deactivation
In exceptional conditions (starting a vehicle which   is   bogged   down,   stuck   in   snow,   on   soft  
g

round...),   it   may   be   advisable   to   deactivate  
t

he   DSC   system,   so   that   the   wheels   can   move  
f

reely   and   regain   grip.
This
 
is
 
indicated
 
by
 
flashing
 
of
 
this
 
w

arning
 
lamp
 
in
 
the
 
instrument

Seat belts
Front seat belts
The front seat belts are fitted with a
pretensioning  and   force   limiting   system.
This
  system   improves   safety   in   the   front  
s

eats   in   the   event   of   a   front   or   side   impact.  
D

epending   on   the   severity   of   the   impact,   the  
p

retensioning   system   instantly   tightens   the   seat  
b

elts   against   the   body   of   the   occupants.
The
  pretensioning   seat   belts   are   active   when  
t

he   ignition   is   on.
The
  force   limiter   reduces   the   pressure   of   the  
s

eat belt on the chest of the occupant, so
improving
  their   protection.Fastening

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  
l

ength   of   the   strap   to   your   size.   The   seat   belt  
i

s   stowed   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  
p

ositioned   as   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  
t

hen   releasing   it   so   that   it   reels   in   slightly.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

In the event of an impact
Depending on the nature and
seriousness of the impact , the
pretensioning
  device   may   be   deployed  
b

efore   and   independently   of   the   airbags.  
D

eployment   of   the   pretensioners   is  
a

ccompanied   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  
s

ystem   checked,   and   if   necessary   replaced,  
b

y   a   CITROËN   dealer   or   a   qualified  
w

orkshop.

Airbags
System designed to contribute towards improving   the   safety   of   the   occupants   (with  
t

he   exception   of   the   rear   centre   passenger)  
i

n   the   event   of   violent   collisions.   The   airbags  
s

upplement   the   action   of   the   force-limiting  
s

eat   belts   (with   the   exception   of   the   centre   rear  
p

assenger).
If a collision occurs, the electronic detectors
record
  and   analyse   the   front   and   side   impacts  
s

ustained   in   the   impact   detection   zones:
-
 
i
n   the   case   of   a   serious   impact,   the   airbags  
a

re deployed instantly and contribute
towards better protection of the occupants
of
  the   vehicle   (with   the   exception   of   the  
r

ear   centre   passenger);   immediately   after  
t

he   impact,   the   airbags   deflate   rapidly   so  
t

hat   they   do   not   hinder   visibility   or   the   exit  
o

f the occupants,
-
 
i
n   the   case   of   a   minor   or   rear   impact   or   in  
c

ertain   roll-over   conditions,   the   airbags  
m

ay   not   be   deployed;   the   seat   belt  
a

lone   contributes   towards   ensuring   your  
p

rotection   in   these   situations.
The airbags do not operate when the
ignition is switched off.
This
  equipment   will   only   deploy   once.  
I

f   a   second   impact   occurs   (during   the  
s

ame   or   a   subsequent   accident),   the  
a

irbag   will   not   be   deployed   again. Deployment
  of   one   or   more   of   the  
a

irbags   is   accompanied   by   a   slight  
e

mission   of   smoke   and   a   noise,   due  
t

o the activation of the pyrotechnic
cartridge
  incorporated   in   the   system.
This
  smoke   is   not   harmful,   but   sensitive  
i

ndividuals   may   experience   slight  
ir

ritation.
The noise of detonation related to the
deployment
  of   one   or   more   airbags   may  
r

esult   in   a   slight   loss   of   hearing   for   a  
s

hort   time.
