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  attach  anything  to  or  lean  any-
thing  against  areas  such  as  the  dash-
board,  steering  wheel  pad  and  lower
portion of the instrument panel. 
These  items  can  become  projectiles
when  the  SRS  driver,  front  passenger
and driver’s knee airbags deploy.
● Do not attach anything to areas such as
a  door,  windshield  glass,  side  door
glass,  front  or  rear  pillar,  roof  side  rail
and assist grip.
● Vehicles  without  a  smart  key  system:
Do  not  attach  any  heavy,  sharp  or  hard
objects  such  as  keys  and  accessories
to  the  key.  The  objects  may  restrict  the
SRS  knee  airbag  inflation  or  be  thrust
into  the  driver’s  seat  area  by  the  force
of  the  deploying  airbag,  thus  causing  a
danger.

WARNING
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or per form any of the following modifications
without consulting your Toyota dealer. 
The  SRS  airbags  may  malfunction  or  deploy  (inflate)  accidentally,  causing
death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs,  modifications,  removal  or  replacement  of  the  steering  wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars or roof side rails
● Repairs  or  modifications  of  the  front  fender,  front  bumper,  or  side  of  the
occupant compartment
● Installation  of  a  grille  guard  (bull  bars,  kangaroo  bar,  etc.),  snow  plows,
winches or roof luggage carrier
● Modifications to the vehicle’s suspension system
● Installation  of  electronic  devices  such  as  mobile  two-way  radios  and  CD
players
● Modifications to your vehicle for a person with a physical disability

SIENNA_OM_OM08007U_(U)The  SRS  curtain  shield  airbags  do  not  generally  inflate  if  the  vehicle  is
involved  in  a  rear  collision,  if  it  pitches  end  over  end,  or  if  it  is  involved  in  a
low-speed side or low-speed frontal collision.
■ When to contact your Toyota dealer
In  the  following  cases,  the  vehicle  will  require  inspection  and/or  repair.  Con-
tact your Toyota dealer as soon as possible.
●Any of the SRS airbags have been inflated.
●
Collision from the rear
● Pitching end over end
● The  front  of  the  vehicle  is  damaged  or
deformed,  or  was  involved  in  an  acci-
dent  that  was  not  severe  enough  to
cause the SRS front airbags to inflate.
● A  portion  of  a  door  or  its  surrounding
area  is  damaged  or  deformed,  or  the
vehicle  was  involved  in  an  accident  that
was  not  severe  enough  to  cause  the
SRS  side  and  curtain  shield  airbags  to
inflate.
● The  pad  section  of  the  steering  wheel,
dashboard  near  the  front  passenger  air-
bag  or  lower  portion  of  the  instrument
panel  is  scratched,  cracked,  or  other-
wise damaged.

*4: The light comes on when the system is turned off. The light flashes fasterthan usual to indicate that the system is operating.
*5: In  order  to  confirm  operation,  the  BS M  outside  rear  view  mirror  indicators
illuminate in the following situations:
• When the engine switch is turned to the “ON” position (vehicles without a smart key system) or IGNITION ON mode (vehicles with a smart key sys-
tem) while the BSM main switch is set to on.
• When the BSM main switch is set to on while the engine switch is in the “ON”  position  (vehicles  without  a  smart  key  system)  or  IGNITION  ON
mode (vehicles with a smart key system).
If the system is functioning correctly, the BSM outside rear view mirror indi-
cators will turn off after a few seconds.
If  the  BSM  outside  rear  view  mirror  indicators  do  not  illuminate  or  do  not
turn off, there may be a malfunction in the system.
If this occurs, have the vehicle inspected by your Toyota dealer.
