CAUTION
Both highpositioned lap belts and
loosefitting belts could cause seri-
ous injuries due to sliding under
the lap belt during a collision or
other unintended result. Keep the
lap belt positioned as low on hips
as possible.
For your safety, do not place the
shoulder belt under your arm.
SB13070
To release the belt, press the bucklere-
lease button and allow the belt to re-
tract.
If the belt does not retract smoothly, pull
it out and check for kinks or twists. Then
make sure it remains untwisted as it re-
tracts.
—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 to
order the proper required length for the
extender. Bring the heaviest coat you ex-
pect to wear for proper measurement and
selection of length. Additional ordering in-
formation is available at your Toyota deal-
er.
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
vehicle accident, increasing the
chance of personal injury.
Never use the seat belt extender if
you can fasten the seat belt without
it.

Remember that the extender pro-
vided for you may not be safe when
used on a different vehicle, or for
another person or at a different
seating position than the one origi-
nally intended for.
SB13071
To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the “PRESS” signs on
the bucklerelease 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 bucklerelease 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.
CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the seat belt extender is 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. It cannot
protect an adult occupant or your
child from injury.

—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
if there is 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 15.)
SB13091
The seat belt pretensioner system mainly
consists of the following components and
their locations are shown in the illustra-
tion.
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.

When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of smokelike 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 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
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 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 onoff switch
is in the “ON” position, the passenger air-
bag is activated if there is 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 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 onoff
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.

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, the SRS airbags and seat belt
pretensioners will not operate all together.
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 lowspeed 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 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. In a severe frontal impact, the sensors
detect deceleration and the system trig-
gers the airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the air
bags with nontoxic gas to help
restrain the forward motion of the occu-
pants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with nontoxic 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.

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 section.
