WARNING
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or per form any of the following modifications

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

For safety and security
■If the SRS airbags deploy (inflate)
●Slight  abrasions,  burns,  bruising  etc.,  may  be  sustained  from  SRS  airbags,
due to the extremely high speed deployment (inflation) by hot gases.
● Bruising  and  slight  abrasions  may  result  from  contact  with  a  deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well  as  the  front  seats,  parts  of  the  front  and  rear  pillars,  and  roof  side  rail,
may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.
● For Safety Connect subscribers, if the SRS airbags deploy or in the event of
a  severe  rear-end  collision,  the  system  is  designed  to  send  an  emergency
call  to  the  response  center,  notifying  them  of  the  vehicle’s  location  (without
needing  to  push  the  “SOS”  button)  and  an  agent  will  attempt  to  speak  with
the occupants to ascertain the level of emergency and assistance required.
If the  occupants  are  unable to  communicate,  the agent  automatically treats
the  call  as  an  emergency  and  helps  to  dispatch  the  necessary  emergency
services. ( P. 457)
■ SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 12 -
18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or
deform).
However,  this  threshold  velocity  will  be  considerably  higher  in  the  following
situations: • If  the  vehicle  strikes  an  object,  such  as  a  parked  vehicle  or  sign  pole, which can move or deform on impact
• If  the  vehicle  is  involved  in  an  underride  collision,  such  as  a  collision  in which  the  front  of  the  vehicle  “underrides”,  or  goes  under,  the  bed  of  a
truck
● Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.
● The SRS front airbags for the front pass enger will not activate if there is no
passenger  sitting  in  the  front  passenger  seat.  However,  the  SRS  front  air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied. ( P. 50)
● The SRS seat cushion airbag on the front passenger’s seat will not operate
if the occupant is not wearing a seat belt.

SIENNA_OM_OM08013U_(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.

approximately 3 seconds.
■Recalling the driving position us ing the memory recall function
● Different  driving  positions  can  be  registered  for  each  electronic  key.  There-
fore,  the  driving  position  that  is  recalled  may  be  different  depending  on  the
key being carried.
● If a door other than the driver’s door is unlocked with the smart key system,
the  driving  position  cannot  be  recalled.  In  this  case,  press  the  driving  posi-
tion button which has been set.
■ Customization
The unlock door settings of the memory recall function can be customized. 
(Customizable features:  P. 628)
