ECU TOYOTA SEQUOIA 2007 1.G Owner's Manual

732007 SEQUOIA from Aug. ’07 Prod. (OM34462U)
Toyota strongly urges that the driver and
passengers in the vehicle be properly re-
strained at all times with the seat belts
provided. Failure to do so could increase
the chance of injury and/or the severity of
injury in accidents.
The seat belts provided for your vehicle
are designed for people of adult size,
large enough to properly wear them.
Child. Use a child restraint system ap-
propriate for the child until the child be-
comes large enough to properly wear the
vehicle’s seat belts. See “Child restraint”
on page 108 in this Section for details.
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. According to accident
statistics, the child is safer when properly
restrained in the rear seat than in the
front seat.
If a child must sit in the front seat, the
seat belts should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may cause death or
serious injury to the child. Do not allow any children to stand up or
kneel on either rear or front seats. An
unrestrained child could suffer serious in-
jury or death during emergency braking or
a collision. Also, do not let the child sit
on your lap. Holding a child in your arms
does not provide sufficient restraint.
Pregnant woman.
Toyota recommends the
use of a seat belt. Ask your doctor for
specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips and not on the
waist.
Injured person. Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendation.CAUTION
Persons should ride in their seats
properly wearing their seat belts
whenever the vehicle is moving.
Otherwise, they are much more likely
to suffer serious bodily injury or
death in the event of sudden braking
or a collision.
When using the seat belts, observe
the following:
Use the belt for only one person at
a time. Do not use a single belt for
two or more people—even children.
Avoid reclining the seatback any
more than needed. The seat belts
provide maximum protection in a
frontal or rear collision when the
driver and the front passenger are
sitting up straight and well back in
the seats. If you are reclined, the
lap belt may slide past your hips
and apply restraint forces directly
to the abdomen or your neck may
contact the shoulder belt. In the
event of a frontal co llision, the
more the seat is reclined, the great-
er the risk of death or serious inju-
ry.

Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seat or side doors.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the system.
Keep the belts clean and dry. If
they need cleaning, use a mild soap
solution or lukewarm water. Never
use bleach, dye, or abrasive clean-
ers, or allow them to come into
contact with the belts—they may
severely weaken the belts. (See
“Cleaning the interior” on page 415
in Section 5.)
Replace the belt assembly (includ-
ing bolts) if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.
u13164Ta b
Buckle
Adjust the seat as needed and sit up
straight and well back in the seat. To
fasten your belt, pull it out of the re-
tractor and insert the tab into the
buckle.
You will hear a click when the tab locks
into the buckle.
The seat belt length automatically adjusts
to your size and the seat position.
The retractor will lock the belt during a
sudden stop or on impact. It also may
lock if you lean forward too quickly. A
slow, easy motion will allow the belt to
extend, and you can move around freely. When a passenger ’s shoulder belt is com-
pletely extended and is then retracted
even slightly, the belt is locked in that
position and cannot be extended. This fea-
ture is used to hold the child restraint
system securely. (For details, see “Child
restraint” on page 108 in this Section.) To
free the belt again, fully retract the belt
and then pull the belt out once more.
If the seat belt cannot be pulled out of the
retractor, firmly pull the belt and release
it. You will then be able to smoothly pull
the belt out of the retractor.CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the belt is not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, immediately contact your
Toyota dealer. Do not use the seat
until the seat belt is fixed, because
it cannot protect an adult occupant
or your child from death or serious
injury.

CAUTION
Always make sure the shoulder belt
is positioned across the center of
your shoulder. The belt should be
kept away from your neck, but not
falling off your shoulder. Failure to
do so could reduce the amount of
protection in an accident and cause
death or serious injuries in a colli-
sion.
u13064
To release the belt, press the buckle
release button and allow the belt to
retract.
If the belt does not retract smoothly, pull
it out and check for kinks or twists. Then
make sure it remains untwisted as it re-
tracts.

CENTER SEAT BELT OF THE THIRD
SEATS
The center seat belt of the third seats is
a 3 −point type restraint with 2 buckles.
Both seat belt buckles must be correctly
located and securely latched for proper
operation.
Make sure buckle 1 (with light gray buckle
release button) is securely latched for
ready use of the center seat belt.

Two buckles and tabs for the center
seat belt of the third seats
The two buckles for the center seat belt
of the third seats are distinguished with
colors of the buckle release button. Also
the two tabs have different shape for its
end so that the belt is not buckled in the
wrong place.Buckle 1 (with light gray buckle release
button)—Properly matches with concave
end tab
Buckle 2 (with red buckle release but-
ton)—Properly matches with round end
tab
CAUTION
Make sure the both buckles are cor-
rectly located and securely latched.
Failure to properly match the buckle
and tab may cause death or severe
injury in case of an accident or a
collision.
u13067
To release the concave end tab, insert the
key into the hole on buckle 1 (with light
gray buckle release button) and allow the
belt to retract.

STOWING THE CENTER SEAT BELT OF
THE THIRD SEATS
To stow the center seat belt of the third
seats, pull the seat belt out of its cov-
er. It will automatically roll back part-
way. Roll the seat belt backward and
insert it into the slot of its cover as
shown above. Make sure the tabs are
securely locked in the cover.
Seat belt must be stowed before you fold
the seatback. (See “—Tumbling third seats
for luggage space” on page 59 or
“—Removing third seats” on page 64 in
this Section.)
NOTICE
Stow the center seat belt of the third
seats when not in use.

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.
u13015
To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the “PRESS” signs on
the buckle release buttons of the ex-
tender and the seat belt are both facing
outward as shown.
You will hear a click when the tab locks
into the buckle.
When releasing the seat belt, press on
the buckle release button on the extender,
not on the seat belt. This helps prevent
damage to the vehicle interior and extend-
er itself.As far as the seat belt extender on the
front passenger side is concerned, do not
fail to disconnect the extender from the
seat belt after the above operation in or-
der to activate the front passenger airbag
correctly when getting into the vehicle
next time.
When not in use, remove the extender
and store in the vehicle for future use.
CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the lap and shoulder portions
of the belt and the seat belt extend-
er are not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, immediately contact your
Toyota dealer. Do not use the seat
until the seat belt is fixed, because
it cannot protect an adult occupant
or your child from death or serious
injury.

The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.1. Front airbag sensors
2. Front passenger occupant classification indicator light
3. Front passenger occupant classification system (ECU and sensors)
4. Seat belt pretensioner assemblies
5. Front passenger ’s seat belt buckle switch
6. Airbag sensor assembly
7. SRS warning light The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.
When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non
−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.CAUTION
Do not modify, remove, strike or open
the seat belt pretensioner assemblies,
airbag sensor or surrounding area or
wiring. Failure to follow these instruc-
tions may prevent the seat belt pre-
tensioners from activating correctly,
cause sudden operation of the system
or disable the system, which could
result in death or serious injury. Con-
sult your Toyota dealer about any re-
pair and modification.
NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
front seat belt pretensioners in some
cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Repairs on or near the front seat
belt retractor assemblies
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repairs made on or near the front
fenders, front end structure or con-
sole

Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the deploy-
ing airbags. An infant or child who
is too small to use a seat belt
should be properly secured using a
child restraint system. Toyota
strongly recommends that all in-
fants and children be placed in the
rear seat of the vehicle and proper-
ly restrained. The rear seat is the
safest for infants and children. For
instructions concerning the installa-
tion of a child restraint system, see
“Child restraint” on page 108 in this
Section.The SRS front airbags are designed to
deploy in severe (usually frontal) colli-
sions where the magnitude and duration
of the forward deceleration of the ve-
hicle exceeds the designed threshold
level.
The SRS front airbags will deploy if the
severity of the impact is above the de-
signed threshold level, comparable to an
approximate 25 km/h (15 mph) collision
when the vehicle has the impact straight
into a fixed barrier that does not move or
deform.
However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if the vehicle is involved in an
underride collision (e.g. a collision in
which the front of the vehicle “underrides”,
or goes under, the bed of a truck, etc.).
It is possible that in some collisions
where the forward deceleration of the ve-
hicle is very close to the designed thresh-
old level, the SRS front airbags and the
seat belt pretensioners may not activate
together.
Always wear your seat belts properly.
u13242
Collision from the sideCollision from the rear
Vehicle rollover
The SRS front airbags are not generally
designed to inflate if the vehicle is in-
volved in a side or rear collision, if it
rolls over, or if it is involved in a low
speed frontal collision. But, when ever a
collision of any type causes sufficient
forward deceleration of the vehicle, de-
ployment of the SRS front airbags may
occur.

u13243
Hitting a curb,
edge of pavement
or hard surfaceFalling into or
jumping over a
deep hole
Landing hard or vehicle falling
The SRS front airbags may also deploy
if a serious impact occurs to the under-
side of your vehicle. Some examples
are shown in the illustration.
u13244
The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion. 1. Front airbag sensors
2. Front passenger occupant classification indicator light
3. Airbag module for front passenger (airbag and inflator)
4. Front passenger occupant classification system (ECU and sensors)
5. Front passenger ’s seat belt buckle switch
6. Driver ’s seat belt buckle switch
7. Driver ’s seat position sensor 8. Airbag sensor assembly
9. Airbag module for driver
(airbag and inflator)
10. SRS warning light The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the infla-
tors very quickly fills the airbags with
non− toxic gas to help restrain the forward
motion of the occupants. The front airbags
then quickly deflate, so that there is no
obstruction of the driver ’s vision should it
be necessary to continue driving.
When the airbags inflate, they produce a
loud noise and release some smoke and
residue along with non −toxic gas. This
does not indicate a fire. This smoke may
remain inside the vehicle for some time,
and may cause some minor irritation to
the eyes, skin or breathing. Be sure to
wash off any residue as soon as possible
to prevent any potential skin irritation with
soap and water. If you can safely exit
from the vehicle, you should do so imme-
diately.

The SRS side airbag on the passenger
seat will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the side airbag on the passen-
ger seat may deploy if luggage is put in
the seat, or the seat belt is buckled up,
regardless of the presence of an occupant
in the seat. (As for the front passenger
occupant classification system, see “Front
passenger occupant classification system”
on page 103 in this Section.)
The SRS curtain shield airbag on the pas-
senger side are activated even with no
passenger in the front seat or rear outside
seat.
Roll sensing function:
In response to a vehicle rollover, the cur-
tain shield airbags on both sides work
with the seat belts to help reduce injury
by inflating. The curtain shield airbags
help reduce injuries mainly to the driver ’s,
front passenger ’s or second seat outside
passenger ’s head and help prevent them
from being thrown out of the vehicle. (This
function can be turned off if inflation is
not desired. See “Roll sensing of curtain
shield airbags off switch” on page 107 in
this Section.)
The SRS curtain shield airbags may acti-
vate even when the side airbags are not
activated.Always wear your seat belt properly.
CAUTION
The SRS side airbag and curtain
shield airbag system is designed
only as a supplement to the prima-
ry protection of the driver, front
passenger and second seat outside
passengers seat belt systems. To
ensure maximum protection in an
accident, the driver and all passen-
gers in the vehicle must wear their
seat belts properly. Wearing a seat
belt properly during an accident re-
duces the chances of death or seri-
ous injury or being thrown out of
the vehicle. For instructions and
precautions concerning the seat
belt system, see “Seat belts” on
page 73 in this Section.
Do not allow anyone to lean his/her
head or any part of his/her body
against the door or the area of the
seat, front p
illar, rear pillar or roof
side rail from which the SRS side
airbag and curtain shield airbag
deploy even if he/she is a child
seated in the child restraint system.
It is dangerous if the SRS side air-
bag and curtain shield airbag in-
flate, and the impact of the deploy-
ing airbag could cause death or se-
rious injury to the occupant.
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the deploy-
ing airbags. An infant or child who
is too small to use a seat belt
should be properly secured using a
child restraint system. Toyota
strongly recommends that all in-
fants and children be placed in the
rear seats of the vehicle and prop-
erly restrained. The rear seats are
the safest for infants and children.
For instructions concerning the
installation of a child restraint sys-
tem, see “Child restraint” on page
108 in this Section.
