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.

After
  an   impact,   have   the   system  
c

hecked   by   a   CITROËN   dealer   or   a

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

Grip control
Special patented traction control system which improves   traction   on   snow,   mud   and   sand.
This
  system,   the   operation   of   which   has   been  
o

ptimised   for   each   situation,   allows   you   to  
m

anoeuvre   in   most   conditions   of   poor   grip  
(

a

  compromise   between   safety,   adhesion   and

raction.   These   tyres   work   equally   well   in   winter  
a

nd   summer.
A five-position selector allows you to choose
the
  setting   best   suited   to   the   driving   conditions

countered.
An

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

Airbags
General information
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   seat   belts   fitted  
w

ith   force   limiters   (all   except   the   centre   rear  
p

assenger
 b
elt).
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.
