CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the lap and shoulder portion of
the belt and the seat belt extender
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 injury.
The driver and front outside passenger
seat belt pretensioners are designed to
be activated in response to a severe
frontal impact.
When the sensor detects a severe frontal
impact, the front outside seat belts are
quickly drawn back by the retractors so
that the belts snugly restrain the occu-
pants.
The front outside seat belt pretensioners
are activated even with no passenger in
the front outside seat.
The front outside seat belt pretensioners
and SRS airbags may not operate together
in all collisions.Collisions occurring at certain s
peeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.

The front outside seat belt pretensioner
system consists mainly of the following
components and their locations are shown
in the illustration.1. Front airbag sensors
2. SRS warning light
3. Seat belt pretensioner assemblies
4. Airbag sensor assembly
The front outside seat belt pretensioners
are controlled by the airbag sensor as-
sembly. The airbag sensor assembly con-
sists of a safing sensor and airbag sen-
sor. When the front outside seat belt preten-
sioners are activated, 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 front outside seat belt preten-
sioners have been activated, the seat belt
retractors remain locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Failure to follow
these instructions may prevent the
front outside seat belt pretensioners
from activating correctly, cause sud-
den operation of the system or dis-
able the system, which could result in
death or serious injury. Consult your
Toyota dealer about any repair and
modification.

Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
front outside seat belt pretensioners
in some cases.

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.The SRS front airbag system mainly con-
sists of the following components, and
their locations are shown in the illustra-
tion. 1. Front airbag sensors
2. Airbag module for driver (airbag and inflator)
3. Airbag module for front passenger (airbag and inflator)
4. Driver ’s seat belt buckle switch
5. Driver ’s seat position sensor
6. Airbag sensor assembly
7. 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 air
bags with
nontoxic 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 nontoxic 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.

Do not put anything or any part of
your body on or in front of the
dashboard or steering wheel pad
that houses the front airbag sys-
tem. They might restrict inflation or
cause death or serious injury as
they are projected rearward by the
force of the deploying airbags. Like-
wise, the driver and front passenger
should not hold objects in their
arms or on their knees.
Do not modify or remove any wir-
ing. Do not modify, remove, strike
or open any components such as
the steering wheel pad, steering
wheel, column cover, dashboard
near the front passenger airbag,
front passenger airbag cover, front
passenger airbag or airbag sensor
assembly. Doing so may prevent the
front airbag system from activating
correctly, cause sudden activation
of the system or disable the sys-
tem, which could result in death or
serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair 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
SRS front airbag system in some
cases.

The SRS side airbag system mainly con-
sists of the following components, and
their locations are shown in the illustra-
tion.1. SRS warning light
2. Airbag sensor assembly
3. Side airbag modules (airbag and inflator)
4. Side airbag sensors
The SRS side airbag system is controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor. In a severe side impact, the side airbag
sensor triggers the side airbag inflators.
At this time a chemical reaction in the
inflators quickly fills the air
bags with non
toxic gas to help restrain the lateral mo-
tion of the occupants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with nontoxic 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.
Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats may be hot for several min-
utes, but the airbags themselves will not
be hot. The airbags are designed to inflate
only once.
CAUTION
SRS side airbags inflate with consid-
erable force. To reduce the possibility
of death or serious injury when they
inflate, the driver and front passenger
must:
Wear their seat belts properly
Remain properly seated with their
backs upright and against the seats
at all times.
