Seat belt pretensioners
SB13089
The driver and passenger’s seat belt
pretensioners are designed to be acti-
vated in response to a severe frontal
impact.
When the airbag sensor detects the shock
of a severe frontal impact, the seat belts
are quickly drawn back in by the retrac-
tors so that the belts snugly restrain the
occupants.
The seat belt pretensioners are activated
even with no passenger in the seat.
Collisions occurring at certain speeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.
SB13102
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, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources. (For details, see
Service reminder indicators and warning
buzzers" on page 70 in Section 1−5.)

When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of smoke−like gas
may be released. This gas is harmless
and does not indicate that a fire is occur-
ring.
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. Doing any of these may cause
sudden operation of the seat belt pre-
tensioners 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.
NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
seat belt pretensioners in some
cases.
Installation of electronic devices
such as a mobile two−way radio,
cassette tape player or compact
disc player
 Repairs on or near the seat belt
retractor assemblies

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.
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 when
impacting straight into a fixed barrier that
does not move or deform.
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 that in some collisions at the
lower zone of airbag sensor detection and
activation for the SRS airbags and seat
belt pretensioners will not operate all to-
gether.
For the safety of all occupants, always
wear your seat belts properly.
SC13014
Collision from the rear
Collision from the side Vehicle rollover
The SRS airbags are not designed to
inflate if the vehicle is involved in a
side or rear collision, if it rolls over, or
if it is involved in a low−speed frontal
collision.

The SRS airbags may deploy if a seri-
ous impact occurs to the underside of
your vehicle. Some examples are shown
in the illustration.
SB13094
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 passenger (airbag and inflator)
4. Airbag sensor assembly
5. Airbag module for driver (airbag and inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor. In a severe frontal impact, the sensors
detect deceleration and the system trig-
gers the airbag inflators. Then a chemical
reaction in the inflators quickly fills the
airbags with non−toxic gas to help restrain
the forward motion of the occupants.
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 gas is nor-
mally harmless; however, for those who
have delicate skin, it may cause a minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
any potential 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 swelling.
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.

Do not allow a child to stand up,
or to kneel on the passenger seat.
The airbag inflates with consider-
able 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 seat. For instructions
concerning the installation of a
child restraint system, see Child
restraint" on page 46 in this sec-
tion.
SB13055
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 pas-
senger 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 pad, steering
wheel, column cover, passenger air-
bag cover, passenger airbag or air-
bag sensor assembly. Doing any of
these may cause sudden SRS air-
bag inflation or disable the system,
which could result in death or seri-
ous injury.
Failure to follow these instructions
can result in death or serious injury.

not fastened. Unless the driver fastens the
belt, the light keeps flashing and the
buzzer stops after about 4 to 8 seconds. (c) Passenger ’s Seat Belt Reminder
Light
This light reminds you to buckle up the
passenger ’s seat belt.
Once the ignition key is turned to ON" or
START", the reminder light flashes if a
passenger sits in the passenger seat and
does not fasten the seat belt. Unless the
passenger fastens the belt, the light stays
flashing.
If luggage load is placed on the passen-
ger seat, depending on its weight and how
it is placed on the seat, built−in sensors
in the seat cushion may detect the pres-
sure, causing the reminder light to come
on.
(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
