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 front passenger oc-
cupant classification indicator light
indicates “ON” when using the seat
belt extender for the front passen-
ger seat. If the indicator light indi-
cates “OFF”, disconnect the extend-
er tongue from the seat belt buckle,
then reconnect the seat belt. Recon-
nect the seat belt extender after
making sure the indicator light indi-
cates “ON”. If you use the seat belt
extender while the indicator light
indicates “OFF”, the front passen-
ger airbag and side airbag on the
front passenger side may not acti-
vate correctly, which could cause
death or serious injury in the event
of collision.
Do not recline the front passenger
seatback so far that it touches a
rear seat. This may cause the
“OFF” indicator to be illuminated,
which indicates that the passen-
ger’s airbags will not deploy in the
event of a severe accident. If the
seatback touches the rear seat, re-
turn the seatback to a position
where it does not touches the rear
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.
If an adult sits in the front passen-
ger seat, the occupant classification
indicator light should indicate “ON”.
If the “OFF” indicator is illumina-
ted, 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” indica-
tor still remains illuminated, 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 pressure to the front
passenger seat by resting hands or
legs on the seatback.
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 rear seat should not contact the
front seatbacks.
Do not use a seat accessory, such
as a cushion or seat cover, that
covers the seat cushion surface.
Do not modify or replace the uphol-
stery of the front seat.

2006 TUNDRA from Oct. ’06 Prod. (OM 34458U)
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” in this Section.)
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 front passenger occupant classifica-
tion 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 cau-
tions in “SRS driver airbag and front pas-
senger airbag”, “SRS side airbags and
curtain shield airbags” and “Child restraint”
in this Section. Your vehicle is equipped with a front
passenger occupant classification sys-
tem. The system detects conditions
1—4 (shown in the following table.).
Based on these conditions, the systems
below are activated or deactivated:
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 to ensure the system detects
the conditions correctly:
Do not place a heavy load on the front
passenger seat or its armrest, etc.
Do not attach a commercial seatback
table or other heavy item to the back
of the front passenger seat.
Do not apply pressure to the front pas-
senger seat by resting hands or legs
on the seatback.

2006 TUNDRA from Oct. ’06 Prod. (OM 34458U)
The front passenger occupant classifi-
cation indicator light indicates the ac-
tuation of the front passenger airbag,
side airbag on the front passenger seat
and front passenger ’s seat belt preten-
sioner.
The front passenger occupant classifi-
cation indicator light will indicate “ON”
and “OFF” when the ignition key is
turned to the “ON” position. After
about four seconds, it will go off. After
that, the front passenger occupant clas-
sification system operates and judges
whether to indicate “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:
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 front passenger
seat, make sure the above do 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 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 cor-
rectly. If the “OFF” indicator remains illu-
minated, either ask the passenger to move
to the rear seat, or if that is not possible,
move the front passenger seat fully rear-
ward.
