Seat belt pretensioners
SB13089
The driver and passenger’s seat belt
pretensioners are designed to be acti-
vated in response to a severe frontal
impact.
When the airbag sensor detects the shock
of a severe frontal impact, the seat belts
are quickly drawn back in by the retrac-
tors so that the belts snugly restrain the
occupants.
The seat belt pretensioners are activated
even with no passenger in the seat.
Collisions occurring at certain speeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.
SB13102
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 70 in Section 1−5.)
SB13091
The seat belt pretensioner system mainly
consists of the following components and
their locations are shown in the illustra-
tion.
1. Front airbag sensors
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.

01MY MR2(U) L/O 0008
352001 MR2 (OM17482U)
When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of smoke−like gas
may be released. This gas is harmless
and does not indicate that a fire is occur-
ring.
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. Doing any of these may cause
sudden operation of the seat belt pre-
tensioners or disable the system,
which could result in death or serious
injury.
Failure to follow these instructions
can result in death or serious inju-
ries.
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 two−way 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
SB13102
This seat belt pretensioner system has a
service reminder indicator to inform the
driver of operating problems. If any of the
following conditions occurs, this indicates
a malfunction of the airbags or
pretensioners. 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 ON" posi-
tion, or the light remains on.
The light comes on or flashes while
driving.
If either seat belt does not retract or
cannot be pulled out due to a malfunc-
tion or activation of the relevant seat
belt pretensioner.

In the following cases, contact your Toyota
dealer as soon as possible:
The front part 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.
Either seat belt pretensioner assembly
or surrounding area is scratched,
cracked, or otherwise damaged.
SB13092
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 to reduce inju-
ries mainly to the driver ’s or passenger ’s
head or chest caused by directly hitting
the steering wheel or dashboard. When
the passenger airbag manual on−off switch
is in the ON" position, the passenger air-
bag is activated even with no passenger
in the 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 when the SRS air-
bags are inflated.
CAUTION
A driver or passenger too close to
the steering wheel or dashboard dur-
ing 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.

Indicator light
The passenger airbag system is
equipped with a manual on−off switch
and indicator light. Turning the passen-
ger airbag manual on−off switch clock-
wise to the ON" position makes the
passenger airbag system operational.
Turning the passenger airbag manual
on−off switch counterclockwise to the
OFF" position disables the passenger
airbag system. The indicator light on
the passenger airbag manual on−off
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 on−off 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
on−off 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.

The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
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
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 airbags
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 for the SRS airbags and seat
belt pretensioners will not operate all to-
gether.
For the safety of all occupants, always
wear your seat belts properly.
SC13014
Collision from the rear
Collision from the side Vehicle rollover
The SRS 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 airbags may deploy if a seri-
ous impact occurs to the underside of
your vehicle. Some examples are shown
in the illustration.
SB13094
The SRS airbag system consists mainly of
the following components, and their loca-
tions are shown in the illustration. 1. Front airbag sensors
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. 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 desi
gned 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.

01MY MR2(U) L/O 0008
412001 MR2 (OM17482U)
A crash severe enough to inflate the air-
bags may break the windshield as the
vehicle buckles. In vehicles with a pas-
senger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating airbag.CAUTION
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the driver side and
passenger side seat belt systems.
The occupants can be killed or seri-
ously injured by the inflating air-
bags if they do not wear the avail-
able 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 30 in this section.
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 in this sec-
tion.

CAUTION
Never put a rear−facing child re-
straint system on the passenger
seat with the passenger airbag
manual on−off switch in the ON"
position. In the event of an acci-
dent, the force of the rapid inflation
of the passenger airbag can cause
death or serious injury to the child.
A forward−facing child restraint sys-
tem which belongs to a passenger
risk group should never be put on
the passenger seat with the passen-
ger airbag manual on−off switch in
the ON" position, because the
force of the deploying passenger
airbag could cause death or serious
injury to the child in forward seat-
ing position.
For instructions concerning the
installation of a child restraint sys-
tem, see Child restraint" on page
46 in this section.
SB13053
Do not sit on the edge of the seat
or lean over the dashboard when
the vehicle is in use. The airbags
inflate with considerable speed and
force; you may be killed or serious-
ly injured. Sit up straight and well
back in the seat, and always use
your seat belt properly.

SB13054
Do not allow a child to stand up,
or to kneel on the passenger seat.
The airbag inflates with consider-
able speed and force; the child may
be killed or seriously injured.
Do not hold a child on your lap or
in your arms. Use a child restraint
system in the seat. For instructions
concerning the installation of a
child restraint system, see Child
restraint" on page 46 in this sec-
tion.
SB13055
Do not put objects or your pets on
or in front of the dashboard or
steering wheel pad that houses the
airbag system. They might restrict
inflation or cause death or serious
injury as they are projected rear-
ward by the force of deploying air-
bags. Likewise, the driver and pas-
senger should not hold things in
their arms or on their knees.
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, passenger air-
bag cover, passenger airbag or air-
bag sensor assembly. Doing any of
these may cause sudden SRS air-
bag inflation or disable the system,
which could result in death or seri-
ous injury.
Failure to follow these instructions
can result in death or serious injury.
