dealer as soon as possible:
Any of the SRS side airbags and cur-
tain shield airbags have been inflated.
The portion of the doors (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the SRS side airbags and curtain
shield airbags to inflate.
The surface of the seats with the side
airbag (shaded in the illustration) is
scratched, cracked, or otherwise dam-
aged.
The portion of the front pillars, rear
pillars or headlining (padding) contain-

Your vehicle is equipped with a front
passenger occupant classification sys-
tem. The system detects conditions
1—4 (Shown in the table on page 106)
Based on these conditions, the systems
below are activated or deactivated:
Front passenger airbag
Side airbag on the right front passen-
ger seat
Front passenger ’s seat belt pretension-
er
The system monitors the weight and
load on the right front passenger seat,
and the seat belt buckle switch to de-
termine conditions 1—4.
In order to ensure that the system de-
tects the conditions correctly:
Do not place a heavy load on the right
front passenger seat or the seatback
table, etc.
Do not attach a commercial seatback
table or other heavy item to the back
of the right front passenger seat.

The passenger airbag onoff indicator
light indicates the actuation of the front
passenger airbag, side airbag on the
front passenger seat and front passen-
ger seat belt pretensioner.
The passenger airbag onoff indicator
light will indicate “ON” and “OFF”
when the ignition switch is turned to
the “ON” position. After about four sec-
onds, it will go off. After that, the front
passenger occupant classification sys-
tem operates and judges whether to in-
dicate “ON” or “OFF”.

The indicator light will indicate “OFF”
when the ignition 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 “OFF” indicator is illuminated, one
of the following is likely to have occurred:
Objects are placed under the front pas-
senger seat.
The front passenger seatback is in
contact with the back wall.
To ensure that the system correctly de-
tects the presence or absence of a person
of adult size sitting in the right front pas-
senger seat, make sure that none of the
above occur.
Make sure that the “ON” indicator is illu-
minated when a person of adult size is
seated in the right front passenger seat.
If the “OFF” indicator is illuminated, follow
the procedure below: 1. Turn the ignition off.
2. Make sure the airbag off switch is set to the “AUTO” position.
3. Make sure the right front passenger seat belt is worn correctly. 4. Ask the front passenger to adjust the
seatback to the upright position and to
sit up straight on the center of the seat
cushion, with his/her legs comfortably
extended forward.
5. Turn the ignition on, having the pas- senger remain in that position until the
passenger airbag on −off indicator light
indicates “ON”.
If the “OFF” indicator remains illuminated,
move the right front passenger seat fully
rearward.

The SRS warning light will come on
and the passenger airbag onoff indica-
tor light will indicate “OFF” if there is
a malfunction in the front passenger
occupant classification system. Contact
your Toyota dealer as soon as possible.

∗4: Never install a rear −facing child restraint system on the front passenger seat. A forward− facing child restraint system should only
be installed on the front passenger seat when it is unavoidable. (See “Child restraint” on page 114 in this Section as for inst alling the
child restraint 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.
Make sure the passenger airbag on
off indicator light indicates “ON”
when using the seat belt extender
for the front passenger seat. If the
indicator light indicates “OFF”, dis-
connect the extender tongue from
the seat belt buckle, then reconnect
the seat belt. Reconnect the seat
belt extender after making sure the
indicator light indicates “ON”. If
you use the seat belt extender
while the indicator light indicates
“OFF”, the front passenger airbag
and side airbag on the front pas-
senger side may not activate cor-
rectly, which could cause death or
serious injury in the event of colli-
sion.
Do not recline the front passenger
seatback so far that it touches a
backwall. This may cause the “OFF”
indicator to be illuminated, which
indicates that the passenger ’s air-
bags will not deploy in the event of
a severe accident. If the seatback
touches the backwall, return the
seatback to a position where it
does not touch the backwall.
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.
If an adult sits in the front passen-
ger seat, the passenger airbag on
off indicator light should indicate
“ON”. If the “OFF” indicator is illu-
minated, 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 “OFF”
indicator still remains illuminated,
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 in the buckle before some-
one sits in the front passenger
seat.
Do not place a heavy load on the
front passenger seat, etc.
Do not apply pressure to the front
passenger seat by resting hands or
legs on the seatback.
Do not put objects under the front
passenger seat.
Do not attach any heavy items to
the back of the front passenger
seat.
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 117 in this Section.)

1092007 TUNDRA from Jul. ’07 Prod. (OM34463U)
Do not modify or 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 passenger airbag on−off indicator light
may indicate “ON” (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 forward −facing child
restraint system is installed on the front
passenger seat. Refer to all the cautions
in “—SRS driver airbag and front
passenger airbag” on page 75, “—SRS
side airbags and curtain shield airbags” on
page 94 and “Child restraint” on page 114
in this Section. Your vehicle is equipped with a front
passenger occupant classification sys-
tem. The system detects conditions
1—4 (Shown in the table on page 111)
Based on these conditions, the systems
below are activated or deactivated:
Front passenger airbag
Side airbag on the right front passen-
ger seat
Front passenger ’s seat belt pretension-
er
The system monitors the weight and
load on the right front passenger seat,
and the seat belt buckle switch to de-
termine conditions 1—4.
In order to ensure the system detects
the conditions correctly:
Do not place a heavy load on the right
front passenger seat or the seatback
table, etc.
Do not attach a commercial seatback
table or other heavy item to the back
of the right front passenger seat.
Do not apply pressure to the right front
passenger seat by resting hands or
legs on the seatback.

The indicator light will indicate “OFF”
when the ignition 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 right front passenger
seat but the “OFF” indicator is illuminated,
one of the following is likely to have oc-
curred:
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 rear seat.
To ensure that the system correctly de-
tects the presence or absence of a person
of adult size sitting in the right front pas-
senger seat, make sure that none of the
above occur. Make sure that the “ON” indicator is illu-
minated when a person of adult size is
seated in the right front passenger seat.
If the “OFF” indicator is illuminated, ask
the passenger to sit up straight, well back
in the seat, and with the seat belt worn
correctly. If the “OFF” indicator remains
illuminated, either ask the passenger to
move to the rear seat, or if that is not
possible, move the right front passenger
seat fully rearward.
