To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the ºPRESSº 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.
CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the lap and shoulder portions
of the belt 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.
ÐFront seat belt pretensioners
The driver and front passenger 's seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the front seat
belt is quickly drawn back in by the re-
tractor so that the belt snugly restrains
the front seat occupants.
The seat belt pretensioners are activated
even with no passenger in the front seat.

New L/C100(U)51
This indicator comes on when the igni-
tion key is turned to the ºACCº or
ºONº position. It goes off after about
6 seconds. This means the front seat
belt pretensioners are operating proper-
ly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, seat belt pretensioner assemblies,
warning light, interconnecting wiring and
power sources. (For details, see ºService
reminder indicators and warning buzzersº
in Chapter 1- 5.)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. SRS warning light
3. Seat belt pretensioner assemblies
4. Airbag sensor assembly
The seat belt pretensioner is controlled by
the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor. When a seat belt pretensioner is 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 pretensioner has been
activated, the seat belt retractor remains
locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult in serious injury.
Failure to follow these instructions
can result in serious injuries.

New L/C100(U)53
The SRS (Supplemental Restraint Sys-
tem) airbags are designed to provide
further protection for the driver and
front passenger when added to the pri-
mary protection provided by the seat
belts.
In response to a severe frontal impact,
the SRS airbags work together with the
seat belts to help prevent or reduce injury
by inflating, in order to decrease the likeli-
hood of the driver 's or front passenger 's
head or chest directly hitting the steering
wheel or dashboard. The passenger airbag
is activated even with no passenger in the
front seat.
Be sure to wear your seat belt.
CAUTION
A driver or front passenger too close
to the steering wheel or dashboard
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 front passenger sit as far back
as possible from the dashboard.
All vehicle occupants be properly
restrained using the available seat
belts.
This indicator comes on when the igni-
tion key is turned to the ºACCº or
ºONº position. It goes off after about
6 seconds. This means the SRS airbags
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, inflators, warning light, interconnect-
ing wiring and power sources. (For details,
see ºService remainder indicators and
warning buzzersº in Chapter 1- 5.)
SRS driver and front
passenger airbags

New L/C100(U)
54
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.
There may be the case that the SRS air-
bags will not activate with such an impact
in which the occupant wearing the seat
belt correctly would not get serious injury.
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 ºunderridesº, or goes under,
the bed of a truck, etc.).
It is possible with collision severity at the
marginal level of airbag sensor detection
and activation that only one of your ve-
hicle's two airbags will deploy.
For the safety of all occupants, be sure
to always wear seat belts.
Collision from the rear
Collision from the side Vehicle rollover
The SRS airbags are not designed to
inflate if the vehicle is subjected to a
side or rear impact, if it rolls over, or
if it is involved in a low- speed frontal
collision.

New L/C100(U)55
Hitting a curb,
edge of pavement
or hard materialFalling into or
jumping over a
deep hole
Landing hard or vehicle falling
The SRS airbags may deploy if a seri-
ous impact occurs to the underside of
your vehicle. Some examples are shown
in the illustration.
The SRS airbag system mainly consists 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, sensors detect
deceleration and the system triggers the
airbag inflators. Then a chemical reaction
in the inflators momentarily fills the air-
bags 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 minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
minor 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 swellings.
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.

New L/C100(U)

Do not allow a child to stand up,
or to kneel on the front passenger
seat. The airbag inflates with con-
siderable 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 rear seat. For instruc-
tions concerning the installation of
a child restraint system, see ºChild
restraintº in this chapter.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 front
passenger 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, front passen-
ger airbag cover, front passenger
airbag or airbag sensor assembly.
Doing any of these may cause sud-
den SRS airbag inflation 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.

Depressing the brake pedal repeatedly
may turn on the warning light and buzzer.
It is normal if the light goes out and the
buzzer stops sounding after a few sec-
onds.
CAUTION
Continued driving with an inoperative
brake booster is dangerous.
(b) Driver's Seat Belt Reminder Light
and Buzzer
Once the ignition key is turned to ºONº or
ºSTARTº, the reminder light flashes and
the buzzer sounds if the driver 's seat belt
is not fastened. Unless the driver fastens
the belt, the light keeps on flashing and
the buzzer sounds 4 to 8 seconds.
(c) Front Passenger 's Seat Belt Re- minder Light
Once the ignition key is turned to ºONº or
ºSTARTº, 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 stays flashing. If luggage 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
come on.
(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
ºFuel gaugeº in Chapter 1- 5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ºFuel tank capº in Chapter
1- 2 for instructions.)
c. There is a problem somewhere in your
engine electrical system, automatic trans-
mission electrical system or electronic
throttle control system.
If it comes on while you are driving in
case c, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.

New L/C100(U)97
(g) SRS Warning Light
This light will come on when the igni-
tion key is turned to the ºACCº or
ºONº position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. 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 ºACCº or
ºONº position or remains on.
The light comes on or flashes while
driving. (h) ºABSº Warning Light
This light warns that there is a problem
somewhere in your anti- lock brake sys-
tem.
If it comes on while you are driving, have
your vehicle checked by your Toyota deal-
er as soon as possible. However, it is
normal if the light goes out.
The light will come on when the ignition
key is turned to the ºONº position. After
a few seconds, the light will go off. There
may be the case that the ºABSº warning
light stays on for about 60 seconds after
the engine is started. It is normal if it
goes out after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes off after a few seconds.
When the ºABSº warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti- lock brake system is not assisting
brake performance so that the wheels can
lock- up during sudden braking or braking
on slippery road surfaces.
However, the anti- lock brake system does
not operate when the rear differential is
locked. It is normal operation for the
ºABSº warning light to be on at this time.
CAUTION
While the ºABSº warning light is on,
if either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Toyota dealer.
The brake system warning light
stays on even with the parking
brake being released.
The brake system warning light and
buzzer come on.
In either case, the brakes may not
work properly. If they do not work
well, depress the brake pedal firmly.
(i) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed.
(j) Unengaged ºParkº Warning Light
This light warns that the transmission
ºParkº mechanism is not engaged. If the
four- wheel drive control is in the ºNº posi-
tion while the selector lever is in the ºPº
position, the transmission will disengage
and the wheels will not lock.

Fuel pump shut- off system
In response to a severe impact which
may cause a large amount of vehicle
deformation, the fuel pump shut- off
system stops supplying fuel to the en-
gine to minimize the risk of fuel leak- age.
The fuel pump shut- off system activates
when the impact detection sensor located
in the footwell of the driver's seat detects
an impact larger than specified.
If the fuel pump shut- off system has acti-
vated, you can turn on the fuel pump
shut- off system with the reset switch on
the impact detection sensor. To turn on
the fuel pump and reset the shut- off
switch, push the reset switch for longer
than one second with the vehicle parked
on a level surface.
CAUTION

Inspect the ground under the ve-
hicle before resetting the fuel pump
shut- off system. If you find liquid
leakage on the ground, it is prob-
able that the fuel system has been
damaged and is in need of repair.
In this case, do not reset the fuel
pump shut- off system.
Do not strike or kick the impact
detection sensor. The fuel pump
shut- off system may activate, shut-
ting off the motor and placing the
vehicle in a position to be involved
in an unexpected accident.
The fuel pump shut- off system is de-
signed to activate in a co llision which may
cause a large amount of vehicle deforma-
tion. It does not operate in a small im-
pact.
