The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
There may be the case that the SRS air-
bags will not activate with such an impact
in which the occupant wearing the seat
belt correctly would not get serious injury.
The SRS airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 25 km/h (15 mph) collision in the
U.S.A. and 30 km/h (18 mph) collision in
Canada when impacting straight into a
fixed barrier that does not move or de-
form. If the severity of the impact is below the
above threshold level, the SRS airbags
may not deploy.
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 it is involved in an underride
collision (e.g. a collision in which the nose
of the vehicle ”underrides”, or goes under,
the bed of a truck, etc.).
It is possible with collision severity at the
marginal level of airbag sensor detection
and activation that only one of your ve-
hicle’s two airbags will deploy.
For the safety of all occupants, be sure
to always wear seat belts.
Collision from the rear
Collision from the side Vehicle rollover
The SRS airbags are not designed to
inflate if the vehicle is subjected to a
side or rear impact, if it rolls over, or
if it is involved in a low −speed frontal
collision.

Hitting a curb, edge

deep hole
The SRS airbags may deploy if a seri-
ous impact occurs to the underside of
your vehicle. Some examples are shown
in the illustration.The SRS airbag system mainly consists of
the following components and their loca-
tions are shown in the illustration.
1. Front airbag sensors
2. Airbag module for driver (airbag and inflator)
3. Airbag module for passenger (airbag and inflator)
4. Airbag sensor assembly
5. SRS airbag warning light
The airbag sensor assembly consists of a
safing sensor and airbag sensor. In a severe frontal impact, sensors detect
deceleration and the system triggers the
airbag inflators. Then a chemical reaction
in the inflators momentarily fills the air-
bags with non
−toxic gas to help restrain
the forward motion of the occupants.
When the airbags inflate, they produce a fair-
ly loud noise and release some smoke and
residue along with non −toxic gas. This does
not indicate a fire. This gas is normally harm-
less, however, for those who have delicate
skin, it may cause minor skin irritation. Be
sure to wash off any residue as soon as
possible to prevent minor skin irritation.
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 swellings.
Parts of the airbag module (steering wheel
hub, dashboard) may be hot for several
minutes, but the airbags themselves will
not be hot. The airbags are designed to
inflate only once.
A crash severe enough to inflate the air-
bags may break the windshield as the
vehicle buckles. In vehicles with a pas-
senger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating airbag.

CAUTION
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the driver side and
front passenger side seat belt sys-
tems. The front seat occupants can
be killed or seriously injured by an
inflating airbag if they do not wear
the available seat belts. During sud-
den braking just before a collision,
an unrestrained driver or front pas-
senger can move forward into direct
contact with or close proximity to
the airbag which may then deploy
during the collision. To obtain maxi-
mum protection in an accident, the
driver and all passengers in the ve-
hicle must wear their seat belts.
Wearing a seat belt during an acci-
dent reduces the chances of death
or serious injuries or being thrown
out of the vehicle. For instructions
and precautions concerning the seat
belt system, see ”Seat belts” in this
chapter.
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by a deploying
airbag. 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 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” in this chapter.
Never put a rear −facing child re-
straint system on the front seat be-
cause the force of the rapid infla-
tion of the passenger airbag can
cause death or serious injury to the
child.

Move seat fully back
A for war d −facing child restraint sys-
tem should be allowed to put on
the front seat only when it is un-
avoidable. Always move the seat as
far back as possible, because the
force of a deploying airbag could
cause death or serious injury to the
child. On vehicles with side airbags,
do not allow the child to lean
against the front door or around
the front door even if the child is
seated in the child restraint system.
It is dangerous if the side airbag
inflates, and the impact could cause
death or serious injury to the child.
For instructions concerning the
installation of a child restraint sys-
tem, see ”Child restraint” in this
chapter.
Do not sit on the edge of the seat
or lean over the dashboard when
the vehicle is in use. The airbags
inflate with considerable speed and
force; you may be killed or serious-
ly injured. Sit up straight and well
back in the seat, and always use
your seat belt.

Do not allow a child to stand up,
or to kneel on the front passenger
seat. The airbag inflates with con-
siderable speed and force; the child
may be killed or seriously injured.
Do not hold a child on your lap or
in your arms. Use a child restraint
system in the rear seat. For instruc-
tions concerning the installation of
a child restraint system, see ”Child
restraint” in this chapter.
Do not put objects or your pets on
or in front of the dashboard or
steering wheel pad that houses the
airbag system. They might restrict
inflation or cause death or serious
injury as they are projected rear-
ward by the force of deploying air-
bags. Likewise, the driver and front
passenger should not hold things 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 column cover,
front passenger airbag cover, front
passenger airbag, airbag sensor as-
sembly. Doing any of these may
cause sudden SRS airbag inflation
or disable the system, which could
result in death or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries.

SRS side airbags
The SRS (Supplemental Restraint Sys-
tem) side airbags are designed to pro-
vide further protection for occupants in
the following seats when added to the
primary protection provided by the seat
belts.
Vehicles with separate front seats—The
SRS side airbags are designed to pro-
tect the driver and front passenger.
Vehicles with bench front seats—The
SRS side airbags are designed to pro-
tect the driver and right −front passen-
ger. They are not designed to protect
occupant in the center position. In response to a severe side impact, the
SRS side airbags work together with the
seat belt to help prevent or reduce injury
by inflating, in order to decrease the im-
pact mainly on the driver’s or front pas-
senger ’s chest. The SRS side airbag on
the passenger seat is activated even with
no passenger in the front seat.
Be sure to wear your seat belt.
CAUTION
SRS side airbags inflate with consid-
erable force. To avoid potential death
or serious injury during inflation of a
side airbag, Toyota strongly recom-
mends that the driver and front pas-
senger;
Wear their seat belt
Remain properly seated with their
back against the seat at all times.
This indicator comes on when the igni-
tion key is turned to the ”ACC” or
”ON” position. It goes off after about
6 seconds. This means the SRS side
airbags are operating properly.
The warning light system monitors the air-
bag sensor assembly, inflators, warning
light, interconnecting wiring and power
sources. (For details, see ”Service remind-
er indicators and warning buzzers” in
Chapter 1
−5.)

The SRS side airbag system may not
inflate if the vehicle is subjected to a
collision from the side at an angle, or
a collision to the side of the vehicle
body other than the passenger compart-
ment shown in the illustration, which
impact is not severe enough for the
passenger compartment. There may be the case that the SRS side
airbags will not activate with such an im-
pact in which the occupant wearing the
seat belt correctly would not get serious
injury.
The SRS side airbags are designed to
inflate when the passenger compartment
gets a severe impact from the side.
For the safety of all occupants, be sure
to always wear your seat belt.
Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags are not designed
to inflate if the vehicle is subjected to
a front or rear impact, if it rolls over,
or if it is involved in a low −speed side
collision.
