For safety and security
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on  the  US  motor  vehicle  safety  standards  (FMVSS208).  The  airbag
sensor  assembly  (ECU)  controls  airbag  deployment  based  on  infor-
mation  obtained  from  the  sensors  et c.  shown  in  the  system  compo-
nents  diagram  above.  This  informat ion  includes  crash  severity  and
occupant  information.  As  the  airbags  deploy,  a  chemical  reaction  in
the inflators quickly fills the airbag s with non-toxic gas to help restrain
the motion of the occupants.
WARNING
■ SRS airbag precautions
Observe the following precautions regarding the SRS airbags. 
Failure to do so may cause death or serious injury.
●The  driver  and  all  passengers  in  the  vehicle  must  wear  their  seat  belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
● The  SRS  driver  airbag  deploys  with  considerable  force,  and  can  cause
death  or  serious  injury  especially  if  the  driver  is  very  close  to  the  airbag.
The National Highway Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm)
of  inflation,  placing  yourself  10  in.  (250  mm)  from  your driver  airbag  pro-
vides  you  with  a  clear  margin  of  safety.  This  distance  is  measured  from
the center of the steering wheel to your breastbone. If you sit less than 10
in.  (250  mm)  away  now,  you  can  change  your  driving  position  in  several
ways:
• Move your seat to the rear as far as you can while still reaching the ped- als comfortably.
• Slightly recline the back of the seat. 
Although vehicle designs vary, many drivers can achieve the 10 in. (250
mm)  distance,  even  with  the  driver  seat  all  the  way  forward,  simply  by
reclining  the  back  of  the  seat  somewhat.  If  reclining  the  back  of  your
seat makes it hard to see the road, raise yourself by using a firm, non-
slippery cushion, or raise the seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the air-
bag toward your chest instead of your head and neck.
The  seat  should  be  adjusted  as  recommended  by  NHTSA  above,  while
still  maintaining  control  of  the  foot  pedals,  steering  wheel,  and  your  view
of the instrument panel controls.

4-5. Using the driving support systems
■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●The buzzer sounds faster as the vehicle approaches an obstacle. 
When  the  vehicle  comes  within  the  following  distance  of  the
obstacle, the buzzer sounds continuously.
• Front and rear corner sensors: Approximately 0.8 ft. (25 cm)
• Rear center sensors: Approximately 1.1 ft. (35 cm)
● When  2  or  more  obstacles  are  detected  simultaneously,  the
buzzer  system  responds  to  the  nearest  obstacle.  If  one  or  both
come  within  the  above  distance s,  the  beep  will  repeat  a  long
tone, followed by fast beeps.
Approximately 2.0 ft. (60 cm)
Approximately 2.8 ft. (85 cm)
Approximately 5.9 ft. (180 cm)
The  diagram  shows  the  detection
range of the sensors. Note that the
sensors  cannot  detect  obstacles
that  are  extremely  close  to  the
vehicle.
The  range  of  the  sensors  may
change depending on the shape of
the object etc.

Votre  véhicule  est  doté  de  COUSSINS  GONFLABLES  ÉVOLUÉS
dont la conception s’appuie sur les normes de sécurité des véhicules
à moteur américains (FMVSS208).  Le module de capteur de coussin
gonflable  (ECU)  contrôle  le  dépl oiement  des  coussins  gonflables  en
fonction des informations obtenues  des capteurs et d’autres éléments
affichés  dans  le  diagramme  des  composants  du  système  ci-dessus.
Ces  informations  comprennent  des  données  relatives  à  la  gravité  de
l’accident et aux occupants. Au moment du déploiement des coussins
gonflables,  une  réaction  chimique  se  produit  dans  les  gonfleurs  de
coussin  gonflable  et  les  coussins  gonflables  se  remplissent  rapide-
ment  d’un  gaz  non  toxique  pour  aider  à  limiter  le  mouvement  des
occupants.
