NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.
Your vehicle is equipped with a front
passenger occupant classification sys-
tem. This system detects the conditions
1—4 in the table on page 137 and based
on these conditions activates or deacti-
vates the following systems;
Front passenger airbag
Side airbag on the front passenger
seat
Front passenger ’s seat belt pretension-
er
The system monitors the weight and
load on the front passenger seat, and
the seat belt buckle switch to determine
conditions 1—4.
In order for the system to detect the
conditions correctly, do not do any of
the following:
Apply a heavy load to the front pas-
senger seat or equipment (e.g. seat-
back table, grocery bag hooks, armrest
or auxiliary box).
Attach a commercial seatback table,
etc. to the front passenger seat seat-
back.
Put weight on the front passenger seat
by putting your hands or feet on the
seatback from the rear passenger seat.
The “AIR BAG ON” and “AIR BAG OFF”
indicator lights indicate the actuation of
the front passenger airbag, side airbag
on the front passenger seat and front
passenger ’s seat belt pretensioner.
The “AIR BAG OFF” indicator light will be
illuminated when the engine switch is in
the “ON” position with the condition 2 in
the table shown below.

If the front passenger occupant classifica-
tion system determines that a person of
adult size sits in the front passenger seat
but the “AIR BAG OFF” indicator light is
illuminated, one of the following is likely
to have occurred:
A rear passenger lifts the front passen-
ger seat cushion with their legs.
Objects are placed under the front pas-
senger seat.
The front passenger seatback is in
contact with the second seat.
To ensure the system correctly detects an
adult sitting in the front passenger seat,
make sure the above do not occur.
Make sure that the “AIR BAG ON” indica-
tor light is illuminated when an adult is
seated in the front passenger seat. If the
“AIR BAG OFF” indicator light is illumina-
ted, ask the passenger to sit up straight,
well back in the seat, and with the seat
belt worn correctly. If the “AIR BAG OFF”
indicator light still remains illuminated, ei-
ther ask the passenger to move to the
rear seat, or if that is not possible, move
the front passenger seat fully rearward. The “AIR BAG ON” and “AIR BAG OFF”
indicator lights will be illuminated ini-
tially when the engine switch is turned
to the “ON” position. After about 4 sec-
onds, they will go off. After that, the
front passenger occupant classification
system operates and judges which indi-
cator light be illuminated.
The SRS warning light and “AIR BAG
OFF” indicator light will come on if
there is a malfunction in the front pas-
senger occupant classification system.

CAUTION
To avoid potential death or serious
injury when the front passenger occu-
pant classification system does not
detect the conditions correctly, ob-
serve the following.
Do not recline the front passenger
seat seatback so that it interferes
with a second seat as it may cause
the “AIR BAG OFF” indicator light
be illuminated. If the seatback inter-
feres with the second seat, return
the seatback to a position where it
does not interfere with the second
seat.
Keep the front passenger seatback
as upright as possible when the ve-
hicle is moving. Reclining the seat-
back excessively may lessen the ef-
fectiveness of the seat belt system.
Make sure the “AIR BAG ON”
indicator light is illuminated when
using the seat belt extender for the
front passenger seat. If the “AIR
BAG OFF” indicator light is
illuminated, disconnect the extender
tongue from the seat belt buckle,
then reconnect 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” indicator
light is illuminated, the front
passenger airbag and side airbag
on the front passenger side may
not activate correctly, which could
cause death or serious injury in the
event of co llision.If an adult sits in the front
passenger seat, the “AIR BAG ON”
indicator light should be illumi-
nated. If the “AIR BAG OFF”
indicator light 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 light still remains illumi-
nated, either ask the passenger to
move to the rear seat, or if that is
not possible, move the front
passenger seat fully rearward.
Wear the seat belt properly.
Make sure the front passenger ’s
seat belt tab has not been left in-
serted into the buckle before some-
one sits in the front passenger
seat.
Do not apply a heavy load to the
front passenger seat or equipment
(e.g. seatback table, grocery bag
hooks, armrest or auxiliary box).
Do not put weight on the front pas-
senger seat by putting your hands
or feet on the front passenger seat
seatback from the rear passenger
seat.

08 SIENNA_U (L/O 0801)
139
2008 SIENNA from Aug. ’08 Prod. (OM45455U)
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.
Child restraint systems installed on
the second seat should not contact
the front seatbacks.
When it is unavoidable to install the
forwardfacing child restraint sys-
tem on the front passenger seat,
install the child restraint system on
the front passenger seat in the
proper order. (As for the installation
order, see “—Installation with seat
belt” on page 142 in this Section.)
Do not remove the front seats.
Do not kick the front passenger
seat or subject it to severe impact.
Otherwise, the SRS warning light
may come on to indicate a malfunc-
tion of the detection system. In this
case, contact your Toyota dealer im-
mediately.
The “AIR BAG ON” indicator light may be
illuminated (the front passenger airbag and
side airbag on the front passenger seat
may deploy) even if observing the above
cautions, when a child sits in, or a for-
ward−facing child restraint system is
installed on the front passenger seat. Re-
fer to all the cautions in “SRS airbags” on
page 120 and “Child restraint” on page 139
in this Section. Toyota strongly urges the use of ap-
propriate child restraint systems for
children.
The laws of all 50 states in the U.S.A.
and Canada now require the use of a
child restraint system.
Your vehicle conforms to SAEJ1819.
If a child is too large for a child restraint
system, the child s
hould sit in the rear
seat and must be restrained using the
vehicle’s seat belt. See “Seat belts” on
page 108 in this Section for details.
CAUTION
For effective protection in automo-
bile accidents and sudden stops, a
child must be properly restrained,
using a seat belt or child restraint
system depending on the age and
size of the child. Holding a child in
your arms is not a substitute for a
child restraint system. In an acci-
dent, the child can be crushed
against the windshield, or between
you and the vehicle’s interior.

2008 SIENNA from Aug. ’08 Prod. (OM45455U)
Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child,
installed on the rear seat. Accord-
ing to accident statistics, the child
is safer when properly restrained in
the rear seat than in the front seat.
Never install a rearfacing child re-
straint system on the front passen-
ger seat even if the “AIR BAG OFF”
indicator light is illuminated. In the
event of an accident, the force of
the rapid inflation of the front pas-
senger airbag can cause death or
serious injury to the child if the
rearfacing child restraint system is
installed on the front passenger
seat.
A forwardfacing child restraint sys-
tem should be allowed to be
installed on the front passenger
seat only when it is unavoidable.
Always move the seat as far back
as possible even if the “AIR BAG
OFF” indicator light is illuminated,
because the front passenger airbag
could inflate with considerable
speed and force. Otherwise, the
child may be killed or seriously in-
jured.
Do not allow the child to lean his/
her head or any part of his/her
body against the side window or
the area of the seat, front or side
pillars or roof side rails from which
the side airbags or curtain shield
airbags deploy even if the child is
seated in the child restraint system.
It is dangerous if the side airbag
and/or curtain shield airbag inflate,
and the impact could cause death
or serious injury to the child.
Do not use the seat belt extender
when installing a child restraint
system on the front or rear passen-
ger seat. If installing a child re-
straint system with the seat belt
extender connected to the seat belt,
the seat belt will not securely hold
the child restraint system, which
could cause death or serious injury
to the child or other passengers in
the event of collision.
Make sure that you have complied
with all installation instructions pro-
vided by the child restraint
manufacturer and that the system is
properly secured. If it is not se-
cured properly, it may cause death
or serious injury to the child in the
event of a sudden stop or accident.

08 SIENNA_U (L/O 0801)

2008 SIENNA from Aug. ’08 Prod. (OM45455U)
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt. You must
carefully consult the manufacturer ’s
instructions which accompany the child
restraint system.
To provide proper restraint, use a child
restraint system following the manufactur-
er ’s instructions about the appropriate age
and size of the child for the child restraint
system.
Install the child restraint system correctly
following the instructions provided by its
manufacturer. General directions are also
provided under the following illustrations.
The child restraint system should be
installed on the rear seat. According to
accident statistics, the child is safer when
properly restrained in the rear seat than
in the front seat.
When not using the child restraint system,
keep it secured with the seat belt or place
it somewhere other than the passenger
compartment. This will prevent it from in-
juring passengers in the event of a sud-
den stop or accident.Child restraint systems are classified into
the following 3 types depending on the
child’s age and size.
(A) Infant seat
(B) Convertible seat
(C) Booster seat
Install the child restraint system following
the instructions provided by its manufac-
turer.
Your vehicle has anchor brackets for se-
curing the top strap of a child restraint
system.
For instructions about how to use the an-
chor bracket, see “—Using a top strap” on
page 153 in this Section.
The child restraint lower anchorages ap-
proved for your vehicle may also be used.
See “—Installation with child restraint low-
er anchorages” on page 157 in this Sec-
tion.

Never install a rearfacing child re-
straint system on the front passen-
ger seat even if the “AIR BAG OFF”
indicator light is illuminated. In the
event of an accident, the force of
the rapid inflation of the front pas-
senger airbag could cause death or
serious injury to the child if the
rearfacing child restraint system is
installed on the front passenger
seat.
