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.

WARNING
■SRS airbag precautions
●Do  not  sit  on  the  edge  of  the  seat  or
lean against the dashboard.
● Do  not  allow  a  child  to  stand  in  front  of
the  SRS  front  passenger  airbag  unit  or
sit on the knees of a front passenger.
● Do not allow the front seat occupants to
hold items on their knees.
● Do  not  lean  against  the  door,  the  roof
side  rail  or  the  front,  side  and  rear  pil-
lars.
● Do  not  allow  anyone  to  kneel  on  the
passenger  seat  toward  the  door  or  put
their head or hands outside the vehicle.
