—Seat belt extender
If your seat belt cannot be fastened se-
curely because it is not long enough, a
personalized seat belt extender is avail-
able from your Toyota dealer free of
charge.
Please contact your local Toyota dealer so
that the dealer can order the proper re-
quired length for the extender. Bring the
heaviest coat you expect to wear for prop-
er measurement and selection of length.
Additional ordering information is available
at your Toyota dealer.
CAUTION
When using the seat belt extender,
observe the following precautions.
Failure to follow these instructions
could reduce the effectiveness of the
seat belt restraint system in case of
an accident, increasing the chance of
personal injury.
Remember that the extender pro-
vided for you may not be safe when
used on a different vehicle, for
another person, or at a different
seating position than the one origi-
nally intended.
Do not use the seat belt extender
if it is not absolutely necessary.
Do not use the seat belt extender
when installing a child restraint
system on the passenger seat. If
installing a child restraint system
with the seat belt extender con-
nected to the seat belt, the seat
belt will not securely hold the child
restraint system, which could cause
death or serious injury to the child
or other passenger in the event of
collision.
SB13071
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.

352005 MR2 from Aug. ’04Prod. (OM17527U)
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.

372005 MR2 from Aug. ’04Prod. (OM17527U)
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds or flashes.
The light comes on or flashes while
driving.
If any seat belt does not retract or
cannot be pulled out due to a malfunc-
tion or activation of the relevant seat
belt pretensioner.
The seat belt pretensioner assembly or
surrounding area has been damaged.
SB13045a
In the following cases, contact your Toyota
dealer as soon as possible:
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the seat belt pretensioners to operate.
The seat belt pretensioner assembly or
surrounding area is scratched, cracked,
or otherwise damaged.
SB13092a
The SRS (Supplemental Restraint Sys-
tem) airbags are designed to provide
further protection for the driver and
passenger in addition to the primary
safety protection provided by the seat
belts.
In response to a severe frontal impact,
the SRS airbags work together with the
seat belts to help reduce injury by inflat-
ing. The SRS airbags help reduce injuries
mainly to the driver ’s or passenger ’s head
or chest caused by hitting the vehicle in-
terior. When the passenger airbag manual
on−off switch is in the “ON” position, the
passenger airbag is activated if there is
no passenger in the seat.
Always wear your seat belt properly.
SRS driver airbag and
passenger airbag

382005 MR2 from Aug. ’04Prod. (OM17527U)
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 when the SRS air-
bags are inflated.CAUTION
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the driver and pas-
senger seat belt systems. The driv-
er and passenger can be killed or
seriously injured by the inflating
airbags if they do not wear the
available seat belts properly. During
sudden braking just before a colli-
sion, an unrestrained driver or pas-
senger can move forward into direct
contact with or close proximity to
the airbag which may then deploy
during the collision. To ensure max-
imum protection in an accident, the
driver and passenger in the vehicle
must wear their seat belts properly.
Wearing a seat belt properly during
an accident reduces the chances of
death or serious injury or being
thrown out of the vehicle. For in-
structions and precautions concern-
ing the seat belt system, see “Seat
belts—” on page 31.
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the deploy-
ing airbags. An infant or child who
is too small to use a seat belt
should be properly secured using a
child restraint system. For instruc-
tions concerning the installation of
a child restraint system, see “Child
restraint—” on page 46.

Indicator light
The passenger airbag system is
equipped with a manual onoff switch
and indicator light. Turning the passen-
ger airbag manual onoff switch clock-
wise to the “ON” position makes the
passenger airbag system operational.
Turning the passenger airbag manual
onoff switch counterclockwise to the
“OFF” position disables the passenger
airbag system. The indicator light on
the passenger airbag manual onoff
switch will come on when the passen-
ger airbag system has been disabled.
See “Passenger airbag manual on−off
switch” on page 45 in this Section for
detail.
CAUTION
Make sure that the indicator light is
off.
Do not turn off the passenger air-
bag manual onoff switch except
when a member of a passenger risk
group identified in TABLE 1 is oc-
cupying the passenger seating posi-
tion.
When the passenger airbag manual
onoff switch is turned off, the pas-
senger airbag will not inflate in a
collision and turning off the pas-
senger airbag can reduce the occu-
pant protection which your vehicle
safety systems can provide to you
in certain accidents and increase
the likelihood of serious personal
injuries.

402005 MR2 from Aug. ’04Prod. (OM17527U)
The SRS airbags are designed to deploy
in severe (usually frontal) collisions
where the magnitude and duration of
the forward deceleration of the vehicle
exceeds the designed threshold level.
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 the
vehicle has the impact straight into a fixed
barrier that does not move or deform.
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 the vehicle is involved in an
underride collision (e.g. a collision in
which the front of the vehicle “underrides”,
or goes under, the bed of a truck, etc.).
It is possible that in some collisions
where the forward deceleration of the ve-
hicle is very close to the designed thresh-
old level, the SRS airbags and the seat
belt pretensioners may not activate togeth-
er.
Always wear your seat belts properly.TABLE 1: A PASSENGER RISK GROUP
Infant. An infant (less than 1 year old) who must ride in the front seat because:
Child age 1 to 12. A child age 1 to 12 must ride in the front seat because:
Medical condition. A passenger has a medical condition which according to his or
her physician:
Causes the passenger airbag to pose a special risk for the passenger: and
Makes the potential harm from the passenger airbag in a crash greater than the
potential harm from turning off the airbag and allowing the passenger, even if
belted, to hit the dashboard, or windshield in a crash.
For more detailed information concerning about the passenger risk group, please
contact NHTSA at 1−800−424−9393.

children ages 1 to 12 sometimes must ride in the front because no space is
available in the rear seat(s) of vehicle; or
The child has a medical condition which, according to the child’s physician,
makes it necessary for the child to ride in the front seat so that the driver can
constantly monitor the child’s condition.
Vehicle has no rear seat;
Vehicle has a rear seat too small to accommodate a rear−facing infant seat; or
The infant has a medical condition which, according to the infant’s physician,
makes it necessary for the infant to ride in the front seat so that the driver can

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.

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.
