To use the armrest, pull it down as
shown in the illustration.
NOTICE
To prevent damage to the armrest,
avoid putting heavy loads on it.
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. For details, see “Child
restraint” on page 86.
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
recommendations.
Armrest Seat belts—
—Seat belt precautions

60
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 86.) 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.
22p006a
Take up slack
Keep as low on hips
as possible
Too high
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
death or serious 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.

63
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.
22p008
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.
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.

There are seat belt pretensioners for
both front seats. They 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 retractor so that the
belts snugly restrain the occupants.The front passenger ’s seat belt pretension-
er will not activate if no passenger is
detected in the front passenger seat by
the front passenger occupant classification
system. However, the front passenger’s
seat belt pretensioner may activate if lug-
gage is put on 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 pass
enger occupant
classification system” on page 81.)
The seat belt pretensioner and SRS air-
bags may not operate together in all colli-
sions.
22p237
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. Front passenger occupant classification indicator light
4. Front passenger ’s seat belt buckle switch
5. Front passenger occupant classification system (ECU and sensors)
6. Seat belt pretensioner assemblies
7. Airbag sensor assembly

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.
The SRS front passenger airbag will not
activate if there is no passenger sitting in
the front passenger seat. However, the
front passenger airbag may deploy if lug-
gage 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 81.)
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 in-
structions and precautions concern-
ing the seat belt system, see “Seat
belts” on page 58.
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 86.

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. SRS warning light
3. Front passenger occupant classification indicator light
4. Airbag module for front passenger (air- bag and inflator)
5. Passenger ’s seat belt buckle switch
6. Front passenger occupant classification system (ECU and sensors)
7. Driver ’s seat belt buckle switch 8. Driver ’s seat position sensor
9. Airbag sensor assembly
10. Airbag module for driver (airbag and inflator) 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 inflat-
ors very quickly fills the airbags with non
−
toxic gas to help restrain the froward mo-
tion 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.

75
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 pillar, 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
86.
22p025a
The SRS side airbag and curtain shield
airbag system may not activate if the
vehicle is subjected to a collision from
the side at certain angles, or a collision
to the side of the vehicle body other
than the passenger compartment as
shown in the illustration.
The SRS side airbags and curtain shield
airbags are designed to inflate when the
passenger compartment area suffers a se-
vere impact from the side.
Always wear your seat belts properly.
22p026c
Collision from the rear
Collision from the front
Vehicle rollover
The SRS side airbags and curtain shield
airbags are not generally designed to
inflate if the vehicle is involved in a
front or rear collision, if it rolls over,
or if it is involved in a lowspeed side
collision.

76
22p239
The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration.1. SRS warning light
2. Front passenger occupant classification indicator light
3. Curtain shield airbag modules (airbag and inflator)
4. Front passenger occupant classification system (ECU and sensors)
5. Side airbag modules (airbag and inflator)
6. Curtain shield airbag sensors
7. Side and curtain shield airbag sensors 8. Passenger ’s seat belt buckle switch
9. Airbag sensor assembly
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consists of a safing sensor and
airbag sensor.
In a severe side impact, the side and
curtain shield airbag sensor and/or the
curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain
shield airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the airbags with non
−toxic gas to help
restrain the lateral motion of the occu-
pants.
When the airbags inflate, they produce a
fairly 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.

87
A forwardfacing child restraint
system 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, because the front pas-
senger airbag could inflate 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 inju-
ry to the child in the event of a
sudden 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 in-
structions which accompany child re-
straint 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 instructions.
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.

1. Run the lap and shoulder belt throughor 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 you
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 re-
straint system on the seat until the
seat belt is fixed.
22p038c
2. Fully extend the shoulder belt to put itin the lock mode. When the belt is
then retracted even slightly, it cannot
be extended.
To hold the infant seat securely, make
sure the belt is in the lock mode before
letting the belt retract.
