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 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 roof side rail garnish (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
1Ð4 in the table on page 104 and based
on these conditions activates or deacti-
vates front passenger airbags. The sys-
tem monitors the weight and load on
the front passenger seat, and the seat
belt buckle switch to determine condi-
tions 1Ð4. 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.

2005 SEQUOIA from Aug. '04 Prod. (OM34424U)
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 ªOFFº
when the ignition switch is in the ªONº
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 ªOFFº 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 ªONº indicator is illu-
minated when an adult is seated in the
front passenger seat. If the ªOFFº 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
ªOFFº 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 ªONº
and ªOFFº when the ignition key is
turned to the ªONº position. After
about four seconds, it will go off. After
that, the front passenger occupant clas-
sification system operates and judges
whether to indicate ªONº or ªOFFº.
The SRS warning light will come on
and front passenger occupant classifi-
cation indicator light will indicate
ªOFFº if there is a malfunction in the
front passenger 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.

Make sure the front passenger oc-
cupant classification indicator light
indicates ªONº when using the seat
belt extender for the front passen-
ger seat. If the indicator light indi-
cates ªOFFº, 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 ªONº. If you use the seat belt
extender while the indicator light
indicates ªOFFº, 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
ªOFFº 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 ªONº.
If the ªOFFº 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 ªOFFº 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.

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 ªÐInstallation with seat
beltº on page 110 in this Section.)

Do not remove the seat.

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 ªONº (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 ªSRS driver airbag and front pas-
senger airbagº on page 86 and ªChild re-
straintº on page 107 in this Section.
The roll sensing of curtain shield air-
bags off switch (ªRSCA OFFº 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 ªRSCA OFFº switch
for a few seconds with the ignition switch
on, the ªRSCA OFFº 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 ªSRS
side airbags and curtain shield airbagsº on
page 93 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 ªSRS side airbags and curtain
shield airbagsº on page 93 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
ªÐSeat belt pretensionersº on page 83 in
this Section.)
If the ignition switch is turned to ªACCº or
ªLOCKº with the roll sensing function off
and then the ignition switch is turned back
to ªONº, the roll sensing function will turn
back on automatically.

CAUTION

Before normal driving, make sure
the ªRSCA OFFº indicator light is
off.

When the roll sensing function is
turned off (and the ªRSCA OFFº
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 SAE J1819.
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 ªSeat beltsº on
page 72 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.

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 rear±facing child re-
straint system on the front passen-
ger seat even if the front passenger
occupant classification indicator
light indicates ªOFFº. In the event
of an accident, the impact of the
rapid inflation of the front passen-
ger airbag could cause death or se-
rious injury to the child if the rear±
facing child restraint system is
installed on the front passenger
seat.

2005 SEQUOIA from Aug. '04 Prod. (OM34424U)

A forward±facing 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 front pas-
senger occupant classification indi-
cator light indicates ªOFFº, because
the front passenger airbag could in-
flate with considerable speed and
force. Otherwise, the child may be
killed or seriously injured.

On vehicles with side airbags and
curtain shield airbags, 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 dangerous if the side
airbag and curtain shield airbag in-
flate, 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 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 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.

(A) INFANT SEAT INSTALLATION
An infant seat must be used in rear±
facing position only.CAUTION

Never install a rear±facing child re-
straint system on the front passen-
ger seat even if the front passenger
occupant classification indicator
light indicates ªOFFº. In the event
of an accident, the impact of the
rapid inflation of the front passen-
ger airbag could cause death or se-
rious injury to the child if the rear±
facing child restraint system is
installed on the front passenger
seat.

Do not install a child restraint sys-
tem on the second (or third) seat if
it interferes with the lock mecha-
nism of the front (or second) seats.
Otherwise, the child or front (or
second) seat occupant(s), may be
killed or seriously injured in case
of sudden braking or a collision.

If the driver 's seat position does
not allow sufficient space for safe
installation, install the child re-
straint system on the second right
seat.
ÐInstallation with seat belt

05_SEQUOIA_U (L/O 0408)

2005 SEQUOIA from Aug. '04 Prod. (OM34424U)
Same angle Same position

When installing a child restraint
system in the third seat center
position, adjust both seat cushions
to the same position and align both
seatbacks at the same angle. Other-
wise, the child restraint system can-
not be securely restrained and this
may cause death or serious injuries
in a collision.1. Run the lap and shoulder belt through
or around the infant seat following the
instructions provided by its manufactur-
er and insert the tab into the buckle
taking care not to twist the belt. Keep
the lap portion of the belt tight.
CAUTION

After inserting the tab, make sure
the tab and buckle are locked and
that the lap and shoulder portions
of the belt are not twisted.

Do not insert coins, clips, etc. in
the buckle as this may prevent your
child from properly latching the tab
and buckle.

If the seat belt does not function
normally, it cannot protect your
child from death or serious injury.
Contact your Toyota dealer immedi-
ately. Do not install the child
restraint system on the seat until
the seat belt is fixed.
