WARNING
■SRS airbag precautions
● If breathing becomes difficult after the SRS airbags have deplo yed, open a
door  or  window  to  allow  fresh  air  in,  or  leave  the  vehicle  if  i t  is  safe  to  do
so. Wash off any residue as soon as possible to prevent skin ir ritation. 
● If the areas where the SRS airbags are stored, such as the steering wheel
pad  and  front  and  rear  pillar  garnishes,  are  damaged  or  cracked ,  have
them replaced by your Toyota dealer.
● Do  not  place  anything,  such  as  a  cushion,  on  the  front  passenger’s  seat.
Doing so will disperse the passenger’s weight, which prevents t he sensor
from detecting the passenger’s weight properly. As a result, th e SRS front
airbags for the front passenger may not deploy in the event of  a collision.
■ Modification and disposal of  SRS airbag system components
Do not dispose of your vehicle or perform 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 airbag s.
● Repairs,  modifications,  removal  or  replacement  of  the  steering  wheel,
instrument panel, dashboard, seats or seat upholstery, front, s ide 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  radio s  and  CD
players.
● Modifications to your vehicle for a person with a physical disa bility.

*1: The  system  judges  a  person  of  adult  size  as  an  adult.  When  a  smaller
adult  sits  in  the  front  passenger  seat,  the  system  may  not  recognize  him/
her as an adult depending on his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt.
*4: For some children, child in seat, child in booster seat or chi ld in convertible
seat, the system may not recognize him/her as a child. Factors  which may
affect this can be the physique or posture.
*5: Never  install  a  rear-facing  child  restraint  system  on  the  front  passenger seat. A forward-facing child restraint system should only be in stalled on the
front passenger seat when it is unavoidable. ( P. 59)
*6: In case the indicator light is not illuminated, consult this m anual on how to
install the child restraint system properly. ( P. 61)
WARNING
■Front passenger occupant classification system precautions
Observe  the  following  precautions  regarding  the  front  passenger  occupant
classification system.
Failure to do so may cause death or serious injury.
● Wear the seat belt properly.
● Make sure the front passenger’s seat belt plate has not been le ft inserted
into the buckle before someone sits in the front passenger seat .
● Make sure the “AIR BAG OFF” indicator light is not illuminated when using
the seat belt extender for the front passenger seat. If the “AI R BAG OFF”
indicator light is illuminated, disconnect the extender tongue  from the seat
belt buckle, and reconnect the seat belt. Reconnect the seat be lt extender
after  making  sure  the  “AIR  BAG  ON”  indicator  light  is  illuminat ed.  If  you
use the seat belt extender while the “AIR BAG OFF” indicator li ght is illumi-
nated,  the  SRS  airbags  for  the  passenger  may  not  activate  corre ctly,
which could cause death or serious injury in the event of a col lision.
● Do not apply a heavy load to the front passenger seat or equipm ent. (e.g.
seatback pocket)
● Do  not  put  weight  on  the  front  passenger  seat  by  putting  your  hands  or
feet on the front passenger seat seatback from the rear passeng er seat.
● Do  not  let  a  rear  passenger  lift  the  front  passenger  seat  with  their  feet  or
press on the seatback with their legs.
● Do not put objects under the front passenger seat.

WARNING
■Front passenger occupant classification system precautions
● Do  not  recline  the  front  passenger  seatback  so  far  that  it  touc hes  a  rear
seat. This may cause the “AIR BAG OFF” indicator light to be il luminated,
which indicates that the passenger’s airbags will not deploy in the event of
a  severe  accident.  If  the  seatback  touches  the  rear  seat,  return  the  seat-
back  to  a  position  where  it  does  not  touch  the  rear  seat.  Keep  the  front
passenger  seatback  as  upright  as  possible  when  the  vehicle  is  m oving.
Reclining  the  seatback  excessively  may  lessen  the  effectiveness  of the
seat belt system.
● If  an  adult  sits  in  the  front  passenger  seat,  the  “AIR  BAG  ON”  indicator
light  is  illuminated.  If  the  “AIR  BAG  OFF”  indicator  is  illuminated,  ask  the
passenger  to  sit  up  straight,  well  back  in  the  seat,  feet  on  the  floor,  and
with  the  seat  belt  worn  correctly.  If  the  “AIR  BAG  OFF”  indicat or  still
remains illuminated, either ask the passenger to move to the re ar seat, or
if that is not possible, move the front passenger seat fully re arward.
● When it is unavoidable to install a forward-facing child restra int system on
the front passenger seat, install the child restraint system on  the front pas-
senger seat in the proper order. ( P. 61)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe im pact. Other-
wise, the SRS warning light may come on to indicate a malfuncti on of the
detection system. In this case, contact your Toyota dealer imme diately.
● Child  restraint  systems  installed  on  the  rear  seat  should  not  c ontact  the
front seatbacks.
● Do not use a seat accessory, such as a cushion and seat cover, that cov-
ers the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.

WARNING
■When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Never  install  a  rear-facing  child  restraint  system  on  the  front   passenger
seat even if the “AIRBAG OFF” indicator light is illuminated. I n the event of
an  accident,  the  force  of  the  rapid  inflation  of  the  front  pass enger  airbag
can  cause  death  or  serious  injury  to  the  child  if  the  rear-facing  child
restraint system is installed on the front passenger seat.
● A  forward-facing  child  restraint  system  may  be  installed  on  the   front  pas-
senger  seat  only  when  it  is  unavoidable.  A  child  restraint  system  that
requires a top tether strap should not be used in the front passenger seat
since there is no top tether strap anchor for the front passenger seat.
● A  forward-facing  child  restraint  system
may be installed on the front passenger
seat  only  when  it  is  unavoidable.  When
installing a forward-facing child restraint
system  on  the  front  passenger  seat,
move  the  seat  as  far  back  as  possible
even if the “AIRBAG OFF” indicator light
is illuminated. 
If  the  head  restraint  interferes  with  the
child  restraint  system  installation  and
the  head  restraint  can  be  removed,
remove the head restraint.
● Do  not  allow  the  child  to  lean  his/her
head or any part of his/her body against
the door or the area of the seat, front or
rear pillars, or roof side rails from which
the  SRS  side  airbags  or  SRS  curtain
shield airbags deploy even if the child is
seated in the child restraint system. It is
dangerous  if  the  SRS  side  airbags  and
curtain  shield  airbags  inflate,  and  the
impact  could  cause  death  or  serious
injury to the child.
