  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

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,

airbags.
  Deployment   of   the   pretensioners  
i

s   accompanied   by   a   slight   discharge   of

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

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.
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

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

  in   the   longitudinal   centreline
 o

f the vehicle on a horizontal plane and directed
from
  the   front   to   the   rear   of   the   vehicle.
