Spark ignition system of
your Toyota
The spark ignition system in your Toyota meets all re-
quirements of the Canadian Interference−Causing Equip-
ment Standard.
Installation of a mobile
two−way radio system
As the installation of a mobile two−way radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system/sequential multiport fuel
injection system, cruise control system, anti−lock brake
system, traction control system, vehicle skid control sys-
tem, SRS airbag system and seat belt pretensioner sys-
tem, be sure to check with your Toyota dealer for pre-
cautionary measures or special instructions regarding
installation.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in
your Toyota contain explosive chemicals. If the vehicle
is scrapped with the airbags and pretensioners left as
they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat
belt pretensioner removed and disposed of by the quali-
fied service shop or by your Toyota dealer before you
dispose of your vehicle.

Seats
While the vehicle is being driven, all ve-
hicle occupants should have the seatback
upright, sit well back in the seat and prop-
erly wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the
occupants are properly seated. Do
not allow sitting on top of a
folded−down seatback, or in the
luggage compartment. Persons not
properly seated and/or properly re-
strained by seat belts can be se-
verely injured in the event of emer-
gency braking or a collision.
During driving, do not allow pas-
sengers to stand up or move
around between seats. Severe inju-
ries can occur in the event of emer-
gency braking or a collision.
CAUTION
The SRS side airbags are installed in
the driver and front passenger seats.
Observe the following precautions.
Do not lean against the front door
when the vehicle is in use. The side
airbag inflates with considerable
speed and force; you may be killed
or seriously injured.
Do not use accessories for the
seats which cover the parts where
the side airbags inflate. Such acces-
sories may prevent the side airbags
from activating correctly, causing
death or serious injury.
Do not modify or replace the seats
or upholstery of the front seats
with the side airbags. Such changes
may disable the system or cause
the side airbags to inflate acciden-
tally, resulting in death or serious
injury. Consult your Toyota dealer if
you insist modifications of this
kind.
Adjust the driver’s seat so that the foot
pedals, steering wheel and instrument
panel controls are within easy reach of
the driver.
CAUTION
Adjustments should not be made
while the vehicle is moving, as the
seat may unexpectedly move and
cause the driver to lose control of
the vehicle.
When adjusting the seat, be careful
not to hit the seat against a pas-
senger or luggage.
After adjusting the seat position,
try sliding it forward and backward
to make sure it is locked in posi-
tion.
After adjusting the seatback, exert
body pressure to make sure it is
locked in position.

NOTICE
Do not put unevenly weighed ob-
jects on the seat and do not stick
sharp objects (needles, nails, etc.)
into the seat.
When cleaning the seats, do not
use organic substances (paint thin-
ner, benzine, alcohol, gasoline,
etc.). They may damage the heater
and seat surface.
To prevent the battery from being
discharged, turn the switch on
when the engine is running.
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.
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. See “Child restraint”
for details.
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. 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 the child 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. It 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.

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 seat belt extender 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. It cannot
protect an adult occupant or your
child from injury.
—Front seat belt pretensioners
The driver and front passenger ’s seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the front seat
belts are quickly drawn back in by the
retractors so that the belts snugly restrain
the front seat occupants.
The front seat belt pretensioners are acti-
vated even with no passenger in the front
seat.
Collisions occurring at certain speeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.

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 front seat
belt pretensioners are operating proper-
ly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, front seat belt
pretensioner assemblies, inflators, warning
light, interconnecting wiring and power
sources. (For details, see “Service remain-
der indicators and warning buzzers” in
Section 1−5.)The front seat belt pretensioner system
mainly consists of the following compo-
nents and their locations are shown in the
illustration.
1. Front airbag sensors
2. SRS warning light
3. Front seat belt pretensioner assemblies
4. Airbag sensor assembly
The front seat belt pretensioners are con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor.When the front seat belt pretensioners are
activated, an operating noise may be
heard and a small amount of smoke−like
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the front seat belt pretensioners
have been activated, the seat belt retrac-
tors 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. Doing any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult in death or serious personal inju-
ry.
Failure to follow these instructions
can result in death or serious inju-
ries.

The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and front passenger in addition to the
primary safety protection provided by
the seat belts.
In response to a severe frontal impact,
the SRS front airbags work together with
the seat belts to help reduce injury by
inflating. The SRS front airbags help to
reduce injuries mainly to the driver ’s or
front passenger ’s head or chest caused by
directly hitting the steering wheel or dash-
board. The front passenger airbag is acti-
vated even with no passenger in the front
seat.
Be sure to wear your seat belt properly.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
A driver or front passenger too close
to the steering wheel or dashboard
during airbag deployment can be
killed or seriously injured. Toyota
strongly recommends that:
The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
The front passenger sit as far back
as possible from the dashboard.
All vehicle occupants be properly
restrained using the available seat
belts.
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 front
airbags are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, front seat belt
pretensioner assemblies, inflators, warning
light, interconnecting wiring and power
sources. (For details, see “Service remind-
er indicators and warning buzzers” in Sec-
tion 1−5.)

The SRS front airbag system is de-
signed to activate in response to a se-
vere frontal impact within the shaded
area between the arrows in the illustra-
tion.
The SRS front airbags will deploy if the
severity of the impact is above the de-
signed threshold level, comparable to an
approximate 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 front air-
bags 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 the SRS airbags and seat belt
pretensioners will not operate all together.
For the safety of all occupants, always
wear your seat belts properly.
Collision from
the rear
Collision from the side
Vehicle rollover
The SRS front 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 front airbags may 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. Airbag module for driver (airbag and
inflator)
3. Airbag module for front passenger (air-
bag and inflator)
4. Airbag sensor assembly
5. SRS warning light
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 designed 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.
