The SRS front airbag system mainly con-
sists of the following components, and
their locations are shown in the illustra-
tion.1. Front airbag sensors
2. SRS warning light
3. Airbag module for front passenger (airbag and inflator)
4. Airbag sensor assembly
5. Airbag module for driver (airbag and inflator)
6. Driver ’s seat position sensor
7. Driver ’s seat belt buckle switch
The airbag sensor assembly consists of a
safing sensor and airbag sensor. 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 air
bags 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
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, 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 are 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.

(a) Brake System Warning Light andBuzzer
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 in the “ON” posi-
tion even after the parking brake is re-
leased.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
When the hydraulic brake booster
fails...
If the hydraulic booster causes an problem
resulting in poor braking performance, the
warning light comes on and buzzer sounds
continuously. Have your vehicle checked at your
Toyota dealer in the following cases:
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 any of the following conditions oc-
cur, 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.
The warning buzzer comes on to-
gether with the warning light.
In either case, this can indicate that
the brakes may not work properly and
your stopping distance will become
longer. Depress 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 anti lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Any of the following conditions may oc-
cur, but do not indicate a malfunction:
The light may stay on for about 60
seconds after the ignition key is turned
to “ON” position. It is normal if it goes
out after a while.
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 af-
ter a few seconds.
You may hear a small sound in the
engine compartment after the engine is
started or the brake pedal is depressed
repeatedly. This is a pump pulsating
sound of the brake system, and it is
not a malfunction.

(h) SRS Warning Light
This light will come on when the igni-
tion key is turned to the ”ON” position.
After about 6 seconds, the light will go
off. This means the system of the air-
bag and front seat belt pretensioners
are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver ’s seat belt buckle switch, front seat
belt pretensioner assemblies, inflators,
warning light, interconnecting wiring and
power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the components monitored by the warning
light system. Contact your Toyota dealer
as soon as possible to service the ve-
hicle.
The light does not come on when the
ignition key is turned to the ”ON” posi-
tion or remains on.
The light comes on or flashes while
driving.If the light stays on, it indicates that the
driver and passenger airbags have a prob-
lem. If the light flashes, the side and cur-
tain shield airbags and/or the seat belt
pretensioners have a problem.
(i) ”ABS” Warning Light
The light comes on when the ignition
key is turned to the “ON” position. If
the anti lock brake system and the
brake assist system work properly, the
light turns off after a few seconds.
Thereafter, if either of the systems mal-
functions, 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, the brake assist
system, the vehicle skid control system
and/or active traction control system do/
does not operate, but the brake system
still operates conventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components 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 “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the anti lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

(n) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver ’s door with
the ignition key in the ”ACC” or ”LOCK”
position.
CHECKING SERVICE REMINDER INDICA-
TORS (except the low fuel level warning
light)1. Apply the parking brake.
2. Open one of the side doors or back door.
The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Place the four wheel drive control lever in ”N” position and the selector lever
in ”P” position.
5. Turn the ignition key to ”ON”, but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light should
come on. The ”ABS”, ”VSC/TRAC”,
”VSC OFF”, ”TRAC”, and slip indicator
light go off after a few seconds. The
SRS warning light goes off after about
6 seconds. There may be the case that the ”ABS”,
”VSC/TRAC” and ”VSC OFF” stay on
for about 60 seconds after the ignition
key is turned to “ON” position. It is
normal if they go out after a while.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Toyota
dealer as soon as possible.

When active traction control is applied,
the active traction control system indi-
cator light blinks.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the ac-
tive traction control system is in the self
check mode, and does not indicate mal-
function. When the active traction control
system is operating, you may feel vibra-
tion or hear noise of your vehicle, caused
by operation of the brakes. This indicates
the system is functioning properly.
When getting the vehicle out of mud or
new snow, etc. the active traction control
system will help operate to prevent the
wheels from spinning.
Active traction control system failure
warning
This light warns when there is a problem
somewhere in the active traction control
system.
If the “VSC/TRAC” warning light comes
on, have your vehicle checked by your
Toyota dealer as soon as possible.The brake actuator temperature increases
during the active traction control system
or vehicle skid control system operating.
If the brake actuator temperature becomes
too high while the active traction control
system or vehicle skid control system is
operating, a buzzer will start to sound
intermittently to indicate that the active
traction control system can no longer op-
erate. In this case, immediately stop your
vehicle at a safe place. If the system
continues to operate, the buzzer sound
changes from intermittent to continuous.
(The continuous buzzer sounds for about
3 seconds.) At the time, the “VSC/TRAC”
warning light will come on and the traction
control system temporarily stops operating
in order to protect the brake actuator. (Al-
though the active traction control system
does not operate, there is no problem to
continue your driving.) The system will be
automatically restored after a short time
and “VSC/TRAC” warning light goes off if
the accelerator pedal is released.
When the “ABS” warning light come on,
the active traction control system is not
operating.
The “VSC/TRAC” warning light will come
on when the ignition key is turned “ON”,
and will go off after a few seconds.

Vehicle skid control system failure
warning
These lights warn when there is a prob-
lem somewhere in the vehicle skid control
system or active traction control system.
If the “VSC/TRAC” warning light and “VSC
OFF” indicator light come on, have your
vehicle checked by your Toyota dealer as
soon as possible. However, there is no
problem if the “VSC/TRAC” warning light
comes on when the brake actuator tem-
perature becomes high. (For details, see
“Active traction control system” on page
140.)When the “ABS” warning light comes on,
the vehicle skid control system is not op-
erating.
The “VSC/TRAC” warning light and “VSC
OFF” indicator light will come on when the
ignition key is turned “ON”, and will go off
after a few seconds.
The “VSC/TRAC” warning light and “VSC
OFF” indicator light may stay on for 60
seconds after the ignition key is turned to
“ON” position. It is normal if they go off
after a few seconds.
Depressing the brake pedal repeatedly
may turn on the lights. It is normal if they
go off after a few seconds.
When the “VSC/TRAC” warning light and
“VSC OFF” indicator light come on, the
vehicle skid control system is not operat-
ing, but there is no problem if you contin-
ue to drive.
In the following cases, contact your Toyota
dealer:
The “VSC/TRAC” warning light, “VSC
OFF” indicator light and slip indicator
light do not come on after the ignition
key is turned “ON”.
The “VSC/TRAC” warning light and
“VSC OFF” indicator light remain on af-
ter the ignition key is turned “ON”.
The “VSC OFF” indicator light comes
on while driving without pushing the
center differential lock switch.
CAUTION
Active traction control system, ve-
hicle skid control system and anti
lock brake system are electronic
systems designed to help the driver
maintain control under adverse con-
ditions. They are not a substitute
for safe driving practices. Factors
including speed, road conditions
and driver steering input can all af-
fect whether active traction control
system, vehicle skid control system
and anti lock brake system will be
effective in preventing a loss of
control. Always keep safety driving
in mind. If the slip indicator light
flashes, sounding an alarm, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle skid control sys-
tem may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” on
page 275.)

The brake system warning light may stay
on for about 60 seconds after the ignition
key is turned to “ON” position. It is nor-
mal if the light turns off after a while.
Depressing the brake pedal repeatedly
may turn on the brake system warning
light and buzzer. It is normal if the light
turns off and the buzzer stops sounding
after a few seconds.
You may hear a small sound in the engine
compartment after the engine is started or
the brake pedal is depressed repeatedly.
This is a pump pulsating sound of the
brake system, and it is not a malfunction.
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your brake fluid
pressure reserve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.
ANTI LOCK BRAKE SYSTEM
(with “ABS” warning light)
The anti lock brake system is designed
to automatically help prevent lock up of
the wheels during a sudden braking or
braking on slippery road surfaces. This
assists in providing stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal: When the anti lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking perfor-
mance.
The anti lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph). Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti lock brake sys-
tem.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle begins to move. This means
that the anti lock brake system is in the
self check mode, and does not indicate a
malfunction.
When the anti lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the anti lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the body
and steering wheel. You may also hear
the motor sound in the engine compart-
ment even after the vehicle is stopped.
At the end of the anti lock brake sys-
tem activation, the brake pedal may
move a little forward.

201
CAUTION
Do not overestimate the anti lock
brake system: Although the anti lock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the anti lock brake system does not
provide vehicle control.
Anti lock 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
anti lock 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 anti lock
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.
“ABS” warning light
The light comes on when the ignition
key is turned to the “ON” position. If
the anti lock brake system and the
brake assist system work properly, the
light turns off after a few seconds.
Thereafter, if either of the systems mal-
functions, the light comes on.

202
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti lock brake system, the brake assist
system, the vehicle skid control system
and/or active traction control system do/
does not operate, but the brake system
still operates conventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components 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 “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the anti lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Either of the following conditions may
occur, but do not indicate a malfunc-
tion.
The light may stay on for about 60
seconds after the ignition key is turned
to “ON” position. It is normal if it turns
off after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
turns off after a few seconds. DRUM IN DISC TYPE PARKING BRAKE
SYSTEM
Your vehicle has a drum in disc type
parking brake system. This type of brake
system n
eeds bedding down of the brake
shoes periodically or whenever the parking
brake shoes and/or drums are replaced.
Have your Toyota dealer perform the bed-
ding down.
BRAKE ASSIST SYSTEM
When you slam the brakes on, the
brake assist system judges as an emer-
gency stop and provides more powerful
braking for a driver who cannot hold
down the brake pedal firmly.
When you slam the brakes on, more pow-
erful braking will be applied. At this time,
you may hear a sound in the engine
compartment and feel the vibrations of the
brake pedal. This does not indicate a mal-
function.
The brake assist system becomes opera-
tive after the vehicle has accelerated to
a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).

NOTICE
Do not use axle mounted hitches as
they can cause damage to the axle
housing, wheel bearings, wheels or
tires. Also, never install a hitch which
may interfere with the normal function
of an Energy Absorbing Bumper, if so
equipped.
1 Trailer ball load rating
2 Ball diameter
3 Shank length
4 Shank diameter
TRAILER BALL
Follow these easy steps to properly deter-
mine the correct trailer ball for your ap-
plication:1. Determine the correct trailer ball size for the trailer coupler. Most couplers
are stamped with the required trailer
ball size. The sizes you will most likely
find stamped on the coupler are: Trailer Class Typical Trailer Ball Size
III 2 5/16 in.
II 2 in.
I 1 7/8 in.
2. Select the appropriate trailer ball to match or exceed the gross trailer
weight rating of the trailer. The trailer
ball load rating should be printed on
the top of the ball.
3. When mounted in the ball mount, the threaded ball shank must protrude be-
yond the bottom of the lock washer
and nut at least 2 threads. The trailer
ball shank must be matched to the ball
mount hole diameter size.
