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  
r

ecord   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  
t

owards   better   protection   of   the   occupants  
o

f   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.
Impact detection zones
A. Front  impact   zone.
B. S ide   impact   zone.
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  
d

eployment   of   one   or   more   airbags   may  
r

esult   in   a   slight   loss   of   hearing   for   a  
s

hort   time.
