TOYOTA xB 2006 (in English) Service Manual

31
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 46.) 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
Scion 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.
To o h i g h
Keep as low on
hips as possible
Ta k e u p
slack
Adjust the position of the lap and
shoulder belts.
Position the lap belt as low as possible
on your hips—not on your waist, then ad-
just it to a snug fit by pulling the shoulder
portion upward through the latch plate.
CAUTION
Both highpositioned lap belts and
loosefitting belts could cause seri-
ous injuries due to sliding under
the lap belt during a collision or
other unintended event. Keep the
lap belt positioned as low on hips
as possible.
Do not place the shoulder belt un-
der your arm.

32
Seat belts with an adjustable shoulder
anchor—
Adjust the shoulder anchor position to
your size.
To raise: Slide the anchor up.
To lower: Push in the lock release button
and slide the anchor down.
After adjustment make sure the anchor is
locked in position.
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
serious injuries in a collision.
13A008
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.
CAUTION
Do not separate the buckle with the
light gray buckle release button.
Otherwise, the seat belt may not work
properly. See the information in the
following columns.

REAR CENTER SEAT BELT
The rear center seat belt is a 3−point type
restraint with two buckles. Both seat belt
buckles must be correctly located and se-
curely latched for proper operation.
Make sure buckle 1 is securely latched
for ready use of the center seat belt.
13A045c
Two buckles and tabs for rear center
seat belt.
The two buckles for the rear center seat
belt are distinguished with colors of the
buckle release button. Also the two tabs
have different shapes to prevent the belt
from being buckle in the wrong place.
Tab 1—Matches the light gray buckle release button
Tab 2—Matches the red buckle release button
CAUTION
Make sure that both buckles are cor-
rectly located and securely latched.
Failure to properly match the buckle
and tab may cause severe injury in
case of an accident or a co llision.

34
CAUTION
Do not use the rear center seat belt
with either buckle released. Fastening
only the shoulder belt or lap belt may
cause severe personal injury in case
of sudden braking or a collision.
—Seat belt extender
If your seat belts cannot be fastened se-
curely because they are not long enough,
a personalized seat belt extender is avail-
able from your Scion dealer free of
charge.
Please contact your local Scion dealer to
order the proper required length for the
extender. Bring the heaviest coat you ex-
pect to wear for proper measurement and
selection of length. Additional ordering in-
formation is available at your Scion dealer.
CAUTION
When using the seat belt extender,
observe the following precautions.
Failure to follow these instructions
could reduce the effectiveness of the
seat belt restraint system in case of
an accident, increasing the chance of
personal injury.
Remember that the extender pro-
vided for you may not be safe when
used on a different vehicle, for
another person, or at a different
seating position than the one origi-
nally intended.
13A082

35
If the seat belt extender has been
connected to the driver ’s seat belt
buckle without wearing the seat belt
when using the extender in the
driver ’s seat, the SRS driver ’s air-
bag system will judge that the driv-
er wears the seat belt even if not
wearing it. In this case, the driver ’s
airbag may not activate correctly,
causing death or serious injury in
the event of a collision. Be sure to
wear the seat belt with the seat belt
extender. Otherwise, there will also
not be any effective protection in a
sudden stop or a collision provided
by the seat belt.Be sure to wear the seat belt with-
out the seat belt extender if you
can fasten the seat belt without the
extender.
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.
13A009
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.
When not in use, remove the extender
and store in the vehicle for future use.

36
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
Scion dealer. Do not use the seat
until the seat belt is fixed, because
it cannot protect an adult occupant
or your child from injury.
—Seat belt pretensioners
Both front seats are equipped with seat
belt pretensioners and are designed to
be activated in response to a severe
frontal impact.
When the sensor detects a severe frontal
impact, the front seat belts are quickly
drawn back by the retractors so that the
belts snugly restrain the occupants.
The seat belt pretensioners are activated
even with no passenger in the front seat.
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.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. SRS warning light
3. Seat belt pretensioner assemblies
4. Airbag sensor assembly
The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.

37
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 Scion dealer about any re-
pair and modification.
NOTICE
Do not perform any of the following
changes without consulting your
Scion dealer. Such changes can
interfere with proper operation of the
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
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 seat belt pretensioners are
operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, driver ’s seat position sensor, driver ’s
seat belt buckle switch, passenger ’s seat
belt buckle switch, seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 77.)

38
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Scion dealer as soon as possible.
When the ignition key is turned to the
“ON” position, the light does not come
on or remains on for more than about
6 seconds or flashes.
The light comes on or starts flashing
while driving.
If any seat belt does not retract or
cannot be pulled out due to a malfunc-
tion or activation of the relevant seat
belt pretensioner.
The seat belt pretensioner assembly or
surrounding area has been damaged.
In the following cases, contact your Scion
dealer as soon as possible:
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the seat belt pretensioners to operate.
Either seat belt pretensioner assembly
or surrounding area is scratched,
cracked, or otherwise damaged.
The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and front passenger in addition to the
primary safety protection provided by
the seat belts.
In response to a severe frontal impact,
the SRS front airbags work with the seat
belts to help reduce injury by inflating.
The SRS front airbags help reduce injuries
mainly to the driver’s or front passenger’s
head or chest caused by hitting the ve-
hicle interior.
SRS driver airbag and front
passenger airbag

39
The SRS front passenger airbag is acti-
vated even with no passenger in the front
seat.
Always wear your seat belt properly.CAUTION
The SRS front airbag system is de-
signed only as a supplement to the
primary protection of the driver and
front passenger seat belt systems.
The driver and front passenger can
be killed or seriously injured by the
inflating airbags if they do not wear
the available seat belts properly.
During sudden braking just before
a collision, an unrestrained driver
or front passenger can move for-
ward into direct contact with or
close proximity to the airbag which
may then deploy during the colli-
sion. To ensure maximum protection
in an accident, the driver and all
passengers in the vehicle must
wear their seat belts properly. Wear-
ing a seat belt properly during an
accident reduces the chances of
death or serious injury or being
thrown out of the vehicle. For
instructions and precautions con-
cerning the seat belt system, see
“Seat belts” on page 29.
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. Scion strong-
ly recommends that all infants and
children be placed in the rear seat
of the vehicle and properly re-
strained. The rear seat is the safest
for infants and children. For in-
structions concerning the installa-
tion of a child restraint system, see
“Child restraint” on page 46.

40
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 exceed the designed threshold lev-
el.
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.
Collision from the side
Vehicle rollover
Collision from the rear
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.
Hitting a curb,
edge of pavement
or hard surface Falling 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.
