WARNING
●Do not sit on the edge of the
seat or lean against the dash-
board.
●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 occu-
pants to hold items on their
knees.
●Do not lean against the door,
the roof side rail or the front,
side and rear pillars.
●Do not allow anyone to kneel on
the passenger seat toward the
door or put their head or hands
outside the vehicle.
●Do not attach anything to or
lean anything against areas
such as the dashboard, steering
wheel pad and lower portion of
the instrument panel.
These items can become pro-
jectiles when th e SRS driver,
front passenger and knee air-
bags deploy.

window, front or rear pillar, roof
side rail and assist grip.

421-1. For safe use
Owners Manual_USA_M42C01_en
WARNING
●Do not hang coat hangers or
other hard objects on the coat
hooks. All of these items could
become projectiles and may
cause death or serious injury,
should the SRS curtain shield
airbags deploy.
●If a vinyl cover is put on the area
where the SRS knee airbag will
deploy, be sure to remove it.
●Do not use seat accessories
which cover the parts where the
SRS side airbags inflate as they
may interfere with inflation of
the SRS airbags. Such acces-
sories may prevent the SRS
side airbags from activating cor-
rectly, disable the system or
cause the SRS side airbags to
inflate accidentally, resulting in
death or serious injury.
●Do not strike or apply significant
levels of force to the area of the
SRS airbag components or the
front doors.
Doing so can cause the SRS
airbags to malfunction.
●Do not touch any of the compo-
nent parts immediately after the
SRS airbags have deployed
(inflated) as they may be hot.
●If breathing becomes difficult
after the SRS airbags have
deployed, open a door or win-
dow to allow fresh air in, or
leave the vehicle if it is safe to
do so. Wash off any residue as
soon as possible to prevent skin
irritation.
●If the areas where the SRS air-
bags are stored, such as the
steering wheel pad and front
and rear pillar ga rnishes, are
damaged or cracked, have
them replaced by your Toyota
dealer.
●Do not place anything, such as
a cushion, on the front passen-
ger’s seat. Doing so will
disperse the passenger’s
weight, which prevents the sen-
sor from detecting the passen-
ger’s weight properly. As a
result, the SRS front airbags for
the front passenger may not
deploy in the event of a colli-
sion.
■Modification and disposal of
SRS airbag system compo-
nents
Do not dispose of your vehicle or
perform any of the following modi-
fications without consulting your
Toyota dealer. The SRS airbags
may malfunction or deploy
(inflate) accidentally, causing
death or serious injury.
●Installation, re moval, disassem-
bly and repair of the SRS air-
bags
●Repairs, modific ations, removal
or replacement of the steering
wheel, instrument panel, dash-
board, seats or seat upholstery,
front, side and rear pillars, roof
side rails, front door panels,
front door trims or front door
speakers
●Modifications to the front door
panel (such as making a hole in
it)
●Repairs or modifications of the
front fender, front bumper, or
side of the occupant compart-
ment
●Installation of a grille guard (bull
bars, kangaroo bar, etc.), snow
plows, winches or roof luggage
carrier
●Modifications to the vehicle’s

WARNING
■Front passenger occupant
classification system precau-
tions
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 left
inserted into the buckle before
someone sits in the front pas-
senger seat.

WARNING
●Make sure the “AIR BAG OFF”
indicator light is not illuminated
when using the seat belt
extender for the front passenger
seat. If the “AIR BAG OFF” indi-
cator light is illuminated, discon-
nect the extender tongue from
the seat belt buckle, and recon-
nect the seat belt. Reconnect
the seat belt extender after
making sure the “AIR BAG ON”
indicator light is illuminated. If
you use the seat belt extender
while the “AIR BAG OFF” indi-
cator light is illuminated, the
SRS airbags for the front pas-
senger will not activate, which
could cause death or serious
injury in the ev ent of a collision.
●Do not apply a heavy load to the
front passenger seat or equip-
ment (e.g. seatback pocket).
●Do not put weight on the front
passenger seat by putting your
hands or feet on the front pas-
senger seat seatback from the
rear passenger seat.
●Do not let a rea r passenger lift
the front passenger seat with
their feet or press on the seat-
back with their legs.
●Do not put objects under the
front passenger seat.
●Do not recline t he front passen-
ger seatback so far that it
touches a rear seat. This may
cause the “AIR BAG OFF” indi-
cator light to be illuminated,
which indicates that the SRS
airbags for the front passenger
will not activate in the event of a
severe accident. If the seatback
touches the rear seat, return the
seatback to a position where it
does not touch the rear seat.
Keep the front passenger seat-
back as upright as possible
when the vehicle is moving.
Reclining the seatback exces-
sively may lessen the effective-
ness of the seat belt system.
●If an adult sits i n the front pas-
senger seat, the “AIR BAG ON”
indicator light i s 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” indicator
still remains illumi nated, either
ask the passenger to move to
the rear seat, or if that is not
possible, move the front pas-
senger seat fully rearward.
●When it is unavoidable to install
a forward-facing child restraint
system on the front passenger
seat, install the child restraint
system on the front passenger
seat in the proper order.
(  P. 5 2 )
●Do not modify or remove the
front seats.

WARNING
●Do not kick the front passenger
seat or subject it to severe
impact. Otherwise, the SRS
warning light may come on to
indicate a malfunction of the
front passenger occupant clas-
sification system. In this case,
contact your Toyota dealer
immediately.
●Child restraint systems installed
on the rear seat should not con-
tact the front seatbacks.
●Do not use a seat accessory,
such as a cushion and seat
cover, that covers the seat
cushion surface.
●Do not modify or replace the
upholstery of the front seat.
●Adjust the front passenger seat
so that the head restraint does
not touch the ceiling. If the head
restraint is left in contact with
the ceiling, the system may not
detect the front passenger prop-
erly, leading to improper opera-
tion of the airbags.

■There is a malfunction in the system
*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 passenge r does not wear a seat belt.
*4: For some children, child in seat, child in booster seat or chi ld in convert-
ible seat, the system may not recognize him/her as a child. Fac tors
which may affect this can be the physique or posture.
*5: Never install a rear-facing ch ild restraint system on the front passenger
seat. A forward-facing child restraint system should only be in stalled on
the front passenger sea t when it is unavoidable. ( P.52)
*6: In case the indicator light is not illuminated, consult this m anual on how
to install the child restr aint system properly. (P. 5 0 )

Riding with children
Observe the following pre-
cautions when children are
in the vehicle.
Use a child restraint system
appropriate for the child,
until the child becomes
large enough to properly
wear the vehicle’s seat belt.
 It is recommended that chil-
dren sit in the rear seats to
avoid accidental contact
with the steering wheel,
wiper switch, etc.
Use the rear door child-pro-
tector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
( P.171, 214)
Do not let small children
operate equipment which
may catch or pinch body
parts, such as the power
window, hood, back door,
seats, etc.
WARNING
■When children are in the vehi-
cle
Never leave children unattended
in the vehicle, and never allow
children to have or use the key.
Children may be able to start the
vehicle or shift the vehicle into
neutral. There is also a danger
that children ma y injure them-
selves by playing with the side
windows or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.
