OCCUPANT RESTRAINT SYSTEMS71
MS13081b
The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration.
1. Airbag manual on−off switch
2. SRS warning light
3. Airbag sensor assembly
4. Curtain shield airbag modules
(airbag and inflator)
5. Side and curtain shield airbag sensors
(5−door models)
6. Side airbag modules
(airbag and inflator)
7. Side and curtain shield airbag sensors
(3−door models)
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consists of a safing sensor and
airbag sensor.
In a severe side impact, the side and
curtain shield airbag sensor triggers the
side airbag and curtain shield airbag inflat-
ors. At this time a chemical reaction in
the inflators quickly fills the airbags with
non−toxic 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 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 designed to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats as well as parts of the front,
center and rear pillars, roof side rail and
roof headlining may be hot for several
minutes, but the airbags themselves will
not be hot. The airbags are designed to
inflate only once.

This indicator comes on when the en-
gine switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the SRS side airbags and
curtain shield airbags are operating
properly.
This warning light system monitors the
airbag sensor assembly, side airbag
sensors, side and curtain shield airbag
sensors, airbag manual on−off switch, seat
belt pretensioner assemblies, inflators,
warning light, interconnecting wiring and
power sources. (For details, see “Service
reminder indicators and warning buzzers”
on page 127 in Section 1−6.)
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact any
authorized Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional, as soon as possible.

130GAUGES, METERS AND SERVICE REMINDER INDICATORS
(c) Front Passenger ’s Seat Belt
Reminder Light and Buzzer
The light and buzzer act as a reminder to
have the front passenger buckle up the
seat belt.
Once the engine switch is turned to “ON”
or “START”, the reminder light flashes if
a passenger sits in the front passenger
seat and does not fasten the seat belt.
Unless the front passenger fastens the
belt, the light continues flashing.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for 30 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 90 more seconds. Even if the vehicle
speed drops below 20 km/h (12 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. If the buzzer
still sounds, make sure the driver ’s seat
belt is fastened.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built−in sensors in the seat cushion may
detect the pressure, causing the reminder
light to flash and buzzer to sound.
(d) Charging System Warning Light
This warning light comes on when the
engine switch is turned to the “ON” posi-
tion, and goes off when the engine is
started.
When there are problems in the charging
system while theengine is running, the
warning light comes on.
NOTICE
When the charging system warning
light comes on while the engine is
running, malfunctions such as the en-
gine drive belt being broken may have
occurred. If the warning light comes
on, immediately stop the vehicle in a
safe place and contact any authorized
Toyota dealer or repairer, or another
duly qualified and equipped profes-
sional.
(e) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If the engine oil pressure warning light
comes on, pull off the road to a safe
place and stop the engine immediately.
Call any authorized Toyota dealer or re-
pairer, or another duly qualified and
equipped professional, for assistance. The
“STOP” warning light also comes on at
thesametime.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the engine
oil level is extremely low. It is not de-
signed to indicate low engine oil level, and
the engine oil level must be checked us-
ing the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.

If the light comes on while driving, the
systemdoes not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.

rized Toyota dealer or repairer, or another
duly qualified and equipped professional:
DThe warning light does not come on
after the engine switch is turned to the
“ON” position.

INFORMATION BEFORE DRIVING YOUR TOYOTA201
DYou may hear the anti−lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
DAt the end of the anti−lock brake sys-
tem activation, the brake pedal may
movealittleforward.
CAUTION
Do not overestimate the anti−lock
brake system: Although the anti−lock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti−
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the anti−lock brake system does not
provide vehicle control.
Anti−lock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
anti−lock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
DDriving on rough, gravel or snow−
covered roads.
DDriving with tire chains installed.
DDriving over the steps such as the
joints on the road.
DDriving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti−lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.
