CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the lap and shoulder portions
of the belt and the seat belt extend-
er are 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, because
it cannot protect an adult occupant
or your child from injury.
—Seat belt pretensioners
SB13089a
The driver and passenger seat belt pre-
tensioners are designed to be activated
in response to a severe frontal impact.
When the sensor detects a severe frontal
impact, the seat belts are quickly drawn
back by the retractors so that the belts
snugly restrain the occupants.
The seat belt pretensioners are activated
even if there is no passenger in the seat.
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.
SB13091a
The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.
1. Front airbag sensor
2. Seat belt pretensioner assemblies
3. Airbag sensor assembly
4. SRS warning light
The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.

362005 MR2 from Aug. ’04Prod. (OM17527U)
When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
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. Failure to follow these instruc-
tions may prevent the seat belt pre-
tensioners from activating correctly,
cause sudden operation of the system
or disable the system, which could
result in death or serious injury. Con-
sult your Toyota dealer about any re-
pair and modification.
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 twoway radio,
cassette tape player or compact
disc player
Repairs on or near the seat belt
retractor assemblies
Modification of the suspension sys-
tem
Modification of the front end struc-
ture
Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
Repair made on or near the front
fenders, front end structure or con-
sole
SB13102a
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 77.)
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.

Collision from the rear
Collision from the side
Vehicle rollover
The SRS airbags are not generally 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, whenever a
collision of any type causes sufficient
forward deceleration of the vehicle, de-
ployment of the SRS airbags may oc-
cur.
SB13077
Hitting a curb, edge
of pavement or hard
surfaceFalling 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.
SB13094a
The SRS airbag system consists mainly of
the following components, and their loca-
tions are shown in the illustration.
1. Front airbag sensor
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.

422005 MR2 from Aug. ’04Prod. (OM17527U)
The airbag sensors constantly monitor the
forward deceleration of the vehicle. If an
impact results in a forward deceleration
beyond the designed threshold level, the
system triggers the airbag inflators. At this
time a chemical reaction in the inflators
very quickly fills the airbags with non−tox-
ic gas to help restrain the forward motion
of the occupants. The airbags then quickly
deflate, so that there is no obstruction 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 designed 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.CAUTION
The driver or passenger who is too
close to the steering wheel or dash-
board 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 passenger sit as far back as
possible from the dashboard.
All vehicle occupants be properly
restrained using the available seat
belts.
For instructions and precautions con-
cerning the seating position, see
“—Seat precautions” on page 28.

442005 MR2 from Aug. ’04Prod. (OM17527U)
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, dashboard
near the passenger airbag, passen-
ger airbag cover, passenger airbag
or airbag sensor assembly. Doing
so may prevent the airbag system
from activating correctly, cause sud-
den activation of the system or dis-
able the system, which could result
in death or serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair and modification.NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can in-
terfere with proper operation of the
SRS airbag system in some cases.
Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact

(a) Brake System Warning Light
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
When the parking brake is applied...
This light comes on for a few seconds
when the ignition key is turned to the
“ON” position even after the parking brake
is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Toyota dealer in the following case:
The light does not come on even if the
parking brake is applied when the igni-
tion key is in the “ON” position.
The light does not come on even if the
ignition key is turned on with the park-
ing brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Toyota dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver’s Seat Belt Reminder Light
and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes and
buzzer sounds if the driver ’s seat belt is
not fastened. Unless the driver fastens the
belt, the light continues flashing and the
buzzer stops after about 4 to 8 seconds.
(c) Passenger ’s Seat Belt Reminder
Light
The light acts as a reminder to have the
passenger buckle up the 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. However, if a passenger uses an
additional seat cushion, the light may not
flash even when the seat belt is not
buckled up.
If luggage or other load is placed on the
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.

1372005 MR2 from Aug. ’04Prod. (OM17527U)
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
Antilock 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
antilock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or snow
covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving 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 antilock
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.
SD02002a
“ABS” warning light
The light comes on when the ignition key
is turned to the “ON” position. If the anti−
lock brake system works properly, the
light turns off after a few seconds. There-
after, if the system malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake system does not operate,
but the brake system still operates con-
ventionally.
