srs TOYOTA YARIS 2005 1.G User Guide

292005 ECHO HATCHBACK from Jul. ’04Prod. (OM52624U)
Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seat belt restraint
system by the driver and front passenger
when the SRS airbags are inflated.CAUTION

The SRS airbag system is designed
only as a supplement to the prima-
ry 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 21 in this Section.

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 35 in this
Section.

The SRS airbags are designed to deploy
in severe (usually frontal) collisions
where the magnitude and duration of
the forward deceleration of the vehicle
exceeds the designed threshold level.
The SRS airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 30 km/h (18 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 co llision (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 airbags and the seat
belt pretensioners may not activate toge-
ther.
Always wear your seat belts properly.
SY13027
Collision from the side
Vehicle rollover
Collision from the rear
The SRS airbags are generally not de-
signed 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 airbags may oc-
cur.
SP13021
Hitting a curb,
edge of pavement
or hard surface Falling into or
jumping over a
deep hole
Landing hard or vehicle falling
The SRS airbags may also deploy if a
serious impact occurs to the underside
of your vehicle. Some examples are
shown in the illustration.

The SRS airbag system consists mainly of
the following components, and their loca-
tions are shown in the illustration.1. Front airbag sensors
2. SRS warning light
3. Airbag module for driver (airbag and inflator)
4. Airbag module for front passenger (air- bag and inflator)
5. Airbag sensor assembly
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 forward mo-
tion of the occupants. The airbags then
quickly deflate, so that there is no ob-
struction 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. 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, primarily to the head and chest, it
may also cause other, less severe injuries
to the face, chest, arms and hands. These
are usually in the nature of minor burns
or abrasions and swelling, but the force of
a deploying airbag can cause more seri-
ous injuries, especially if an occupant’s
hands, arms, chest or head is in close
proximity to the airbag module at the time
of deployment. This is why it is important
for the occupant to: avoid placing any
object or part of the body between the
occupant and the airbag module; sit
straight and well back into the seat; wear
the available seat belt properly; and sit as
far as possible from the airbag module,
while still maintaining control of the ve-
hicle.
Parts of the airbag module (steering wheel
hub, airbag cover and inflator) may be hot
for several minutes after deployment, so
do not touch! The airbags inflate only
once. The windshield may be damaged by
absorbing some of the force of the inflat-
ing airbag.

In the following cases, contact your Toyota
dealer as soon as possible:

The SRS airbags have been inflated.

The front part of the vehicle (shaded
in the illustration) was involved in an
accident that was not severe enough to
cause the SRS airbags to inflate.

The pad part of the steering wheel or
front passenger airbag cover (shaded
in the illustration) is scratched,
cracked, or otherwise damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.
Toyota strongly urges the use of ap-
propriate child restraint systems for
children.
The laws of all 50 states in the U.S.A.
and Canada now require the use of a
child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint
system, the child should sit in the rear
seat and must be restrained using the
vehicle’s seat belt. See “Seat belts” for
details.
CAUTION

For effective protection in automo-
bile accidents and sudden stops, a
child must be properly restrained,
using a seat belt or child restraint
system depending on the age and
size of the child. Holding a child in
your arms is not a substitute for a
child restraint system. In an acci-
dent, the child can be crushed
against the windshield, or between
you and the vehicle’s interior.
