2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
The indicator light will indicate “OFF”
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 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.

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.

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
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 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,
either ask the passenger to move to
the rear seat, or if that is not pos-
sible, 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 right front passen-
ger seat.
Do not place a heavy load on the
front passenger seat or the seat-
back table, etc.
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.
Do not attach a commercial seat-
back table or other heavy item to
the back of the right front passen-
ger seat.
Child restraint systems installed on
the rear seat should not contact the
front seatbacks.

11 4
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
When it is unavoidable to install the
forwardfacing child restraint sys-
tem on the front passenger seat,
install the child restraint system on
the right front passenger seat in
the proper order. (As for the instal-
lation order, see “—Installation with
seat belt” on page 128 in this Sec-
tion.)
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 87, “—SRS
side airbags and curtain shield airbags” on
page 95 and “Child restraint” on page 115.

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 offroad driving).
—Roll sensing of curtain
shield airbags off switch

2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
When you push the “RSCA OFF” switch
for a few seconds with the engine 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” on page 95 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” on page 95 in this Sec-
tion.)
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” on page 73 in
this Section.)
If the engine switch is turned to “ACC” or
“LOCK” with the roll sensing function off
and then the engine 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 should sit in the rear
seat and must be restrained using the
vehicle’s seat belt. See “Seat belts” on
page 66 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.

Regular cab models—
Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child.
Double cab and Crew Max 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.
Regular cab models—
Never put infant or child age 1 to
12 in a passenger risk group on the
right front passenger seat with the
passenger airbag off switch in the
“AUTO” position. In the event of an
accident, the force of the rapid
inflation of the front passenger air-
bag can cause death or serious in-
jury to the child.
If you must put infant or child age
1 to 12 in a passenger risk group
on the right front seat, make sure
that the passenger airbag off switch
is in the “OFF” position with the
key removed and that the indicator
light is on. (For details, see “—SRS
driver airbag and front passenger
airbag” on page 77 in this Section.)
Never install a rearfacing child re-
straint system on the front passen-
ger seat even if the passenger air-
bag onoff indicator light indicates
“OFF”. In the event of an accident,
the impact of the rapid inflation of
the front passenger airbag could
cause death or serious injury to the
child if the rearfacing child re-
straint 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 passenger
airbag onoff indicator light indi-
cates “OFF”, because the front pas-
senger airbag could inflate with
considerable speed and force.
Otherwise, the child may be killed
or seriously injured.
Do not allow the child to lean his/
her head or any part of his/her
body against the door or the area
of the seat, front or rear pillar or
roof side rail from which the side
airbags or curtain shield airbags
deploy even if the child is seated in
the child restraint system. It is dan-
gerous if the side airbag and cur-
tain shield airbag inflate, and the
impact could cause death or seri-
ous injury to the child.

2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
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 you have complied with
all installation instructions provided
by the child restraint manufacturer
and that the system is properly se-
cured. If it is not secured properly,
it may cause death or serious injury
to the child in the event of a sud-
den stop or accident.
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 in the rear seat if your vehicle
is equipped with rear seats. 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 139, 142 or 145 in this Section.
The child restraint lower anchorages
approved for your vehicle may also be
used. See “—Installation with child
restraint lower anchorages” on page 147,
149 or 151 in this Section.
