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 ºACCº or
ºONº 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 ºService remind-
er indicators and warning buzzersº in
Chapter 1±5.)The SRS side airbags 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 compartment 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 seat belts.
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.The SRS side airbag system mainly con-
sists of the following components and
their locations are shown in the illustra-
tion.
1. SRS airbag warning light
2. Side airbag modules
(airbag and inflator)
3. Side airbag sensor assemblies
4. Airbag sensor assembly
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.
Then a chemical reaction in the inflators
momentarily fills the airbags with non±tox-
ic gas to help restrain the lateral 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 minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
minor skin irritation.
Deployment of the airbags happen 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 swellings.
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

The SRS side airbag system is de-
signed only as a supplement to the
primary protection of the driver
side and front passenger side seat
belt systems. The front seat occu-
pants can be killed or seriously in-
jured by an inflating airbag if they
do not wear the available seat
belts. During sudden braking just
before a collision, an unrestrained
driver or front passenger can move
sideward into direct contact with or
close proximity to the airbag which
may then deploy during the colli-
sion. To obtain maximum protection
in an accident, the driver and all
passengers in the vehicle must
wear their seat belts. Wearing a
seat belt during an accident re-
duces the chances of death or seri-
ous injuries or being thrown out of
the vehicle. For instructions and
precautions concerning the seat
belt system, see ºSeat beltsº 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
ºChild restraintº in this chapter.

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 instructors concerning the
installation of a child restraint sys-
tem, see ºChild restraintº in this
chapter.

The daytime running light control sensor
is on the top of the passenger 's side
instrument panel.
Do not place anything on the instrument
panel, and/or do not affix anything on the
windshield to block this sensor.High±Low beamsÐFor high beams, turn
the headlights on and push the lever away
from you (position 1). Pull the lever to-
ward you (position 2) for low beams.
The headlight high beam indicator light
(blue light) on the instrument panel will
tell you that the high beams are on.
Flashing the high beam headlights
(position 3)ÐPull the lever all the way
back. The high beam headlights turn off
when you release the lever.
You can flash the high beam headlights
with the knob turned to ºOFFº.TURN SIGNALS
To signal a turn, push the headlight/
turn signal lever up or down to position
1.
The key must be in the ºONº position.
The lever automatically returns after you
make a turn, but you may have to return
it by hand after you change lanes.
To signal a lane change, move the lever
up or down to the pressure point (position
2) and hold it.
If the turn signal indicator lights (green
lights) on the instrument panel flash faster
than normal, a front or rear turn signal
bulb is burned out.

(g) ºABSº Warning Light
This light warns that there is a problem
somewhere in your anti±lock brake sys-
tem.
If the light comes on while you are driv-
ing, have your vehicle checked by your
Toyota dealer as soon as possible.
The light will come on when the ignition
key is turned to the ºONº position. After
a few seconds, the light will go off.
When the ºABSº warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti±lock brake system is not assisting
brake performance so that the wheels can
lock±up during sudden braking or braking
on slippery road surfaces.
(h) Open Door Warning Light
This light remains on until all the doors
and back door are completely closed.
(i) Rear Light Failure Warning Light
If this light comes on when the headlight
switch is turned on (at the first or second
clickstop), it indicates that one or more of
the tail lights are burned out.If it comes on when the brake pedal is
depressed, one or more stop lights are
burned out.
Have defective bulbs replaced as soon as
possible.
(j) SRS Airbag Warning Light
This light will come on when the igni-
tion key is turned to the ºACCº or
ºONº position. After about 6 seconds,
the light will go off. This means the
systems of the airbag and front seat
belt pretensioner are operating properly.
The warning light system monitors the
front airbag sensors, airbag sensor as-
sembly, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.

The light does not come on when the
ignition key is turned to the ºACCº or
ºONº position or remains on.

The light comes on or flashes while
driving.(k) Low Windshield Washer Fluid Level
Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see ºAdding washer fluidº in Chapter 7±3.)
(l) ºTRAC OFFº Indicator/Warning Light
This light comes on when the ignition key
is turned to ºONº, and will go off after 3
seconds. This means that the system is
operating properly.
If one of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.

The light remains on more than 3 se-
conds after the ignition switch is turned
on.

The light comes on while driving even
if the ºTRAC OFFº switch is not
pushed.

The light flashes.

SRS AIRBAG
1. General
The electrically sensing type SRS (Supplemental Restraint System) airbag is designed to help lessen the
shock to the driver and front passenger as a supplement to the seat belt.
A 3-sensor type airbag system detects the deceleration during collision by the front airbag sensors and the
airbag sensor that is enclosed in the airbag sensor assembly.

System Diagram 
The activation processes of the
SRS airbag is as illustrated below.
