This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS side airbags and curtain
shield airbags are operating properly. This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system and indicator light,
front passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, warning light, “RSCA OFF” indicator
light, interconnecting wiring and power
sources. (For details, see “Service remind-
er indicators and warning buzzers” in Sec-
tion 1
−6.)
If either of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds.
The light comes on while driving.
Vehicles with separate seat only—The
SRS warning light will come on and front
passenger occupant classification indicator
light will indicate “OFF” if there is a mal-
function in the front passenger occupant
classification system.

In the following cases, contact your Toyota
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 acci dent
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 roof side rail garnishes (pad-
ding) containing the curtain shield air-
bags inside (shaded in the illustration)
is scratched, cracked, or otherwise
damaged.
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 and based on these
conditions activates or deactivates front
passenger airbags. The system moni-
tors 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.
Put a heavy load on the front passen-
ger seat.
Attach a seatback table to the front
passenger seatback.
Put weight on the front passenger by
putting your hands or feet on the front
passenger seatback from the rear pas-
senger seat.
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 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 the system correctly detects an
adult sitting in the front passenger seat,
make sure the above do not occur.
Make sure that the “ON” indicator is illu-
minated when an adult is seated in the
front passenger seat. If the “OFF” indica-
tor 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 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.
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”.

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 put a heavy load in the
front passenger seatback pocket or
attach a seatback table to the front
passenger seat seatback.
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.
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.

2005 TUNDRA from Aug. ’04 Prod. (OM34427U)
When it is unavoidable to install the
forward −facing 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 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.
The roll sensing of curtain shield air-
bags off switch (“RSCA OFF” switch)
can turn off the curtain shield airbags
and seat belt pretensioners in a vehicle
rollover. This switch should only be
used if inflation is not desired (such as
extreme off −road driving).
When you push the “RSCA OFF” switch
for a few seconds with the ignition switch
on, the “RSCA OFF” indicator light comes
on and the roll sensing function is turned
off. When you push the switch again, the
indicator light goes off and the roll sens-
ing function is turned on. (For details
about the roll sensing function, see “SRS
side airbags and curtain shield airbags” in
this Section.) In a severe side impact, the curtain shield
airbags on impacted side will inflate even
if the roll sensing function is turned off.
(For details about the curtain shield air-
bags, see “SRS side airbags and curtain
shield airbags” in this Section.)
In a severe frontal impact, the seat belt
pretensioners will work even if the roll
sensing function is turned off. (For details
about the seat belt pretensioners, see
“—Seat belt pretensioners” in this Sec-
tion.)
If the ignition switch is turned to “ACC” or
“LOCK” with the roll sensing function off
and then the ignition switch is turned back
to “ON”, the roll sensing function will turn
back on automatically.

CAUTION
Before normal driving, make sure
the “RSCA OFF” indicator light is
off.
When the roll sensing function is
turned off (and the “RSCA OFF”
indicator light is on), the curtain
shield airbags and seat belt preten-
sioners will not work in a vehicle
rollover. Turning off the curtain
shield airbags and seat belt preten-
sioners reduces occupant protection
which your vehicle safety systems
can provide in accidents and in-
crease the likelihood of death or
serious injuries.
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” 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.
Standard and access cab models—
STANDARD CAB MODELS—
Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child.
ACCESS CAB MODELS—
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.
