The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.1. Front airbag sensors
2. SRS warning light
3. Front passenger occupant classification indicator light
4. Airbag module for front passenger (airbag and inflator)
5. Front passenger occupant classification system (ECU and sensors)
6. Front passenger ’s seat belt buckle switch
7. Driver ’s seat belt buckle switch 8. Driver ’s seat position sensor
9. Airbag sensor assembly
10. Airbag module for driver (airbag and inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the infla-
tors very quickly fills the air bags with
non−toxic gas to help restrain the forward
motion of the occupants. The front 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 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 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.

(a) Brake System Warning Light andBuzzer
This light comes on in the following cases
when the engine switch is in the ON"
position.
When the parking brake is applied...
This light comes on for a few seconds
when the engine switch is turned to the
ON" position even after the parking brake
is released.
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 a 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 en-
gine switch is in the ON" position.
The light does not come on even if the
engine switch is turned on with the
parking brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If any of the following conditions oc-
curs, 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 be-
come 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 un-
stable during braking.
Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The light may stay on for about 60
seconds after the engine switch is
turned to the ON" position. It is nor-
mal if it turns off after a while.
Depressing the brake pedal repeatedly
may turn on the 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.

156
You need to reset the light after the en-
gine oil replacement. Reset the light by
following the procedure below:1. Turn the engine switch to the ACC" or LOCK" position with the odometer
reading shown. (For details, see
Odometer and two trip meters" on
page 148 in this Section.)
2. Turn the engine switch to the ON" position while holding down the trip
meter reset button.
Hold down the button until the light goes
off. Before the light goes off, it illuminates
for 3 seconds, flashes for 2 seconds and
illuminates for 1 sec ond.
If the system fails to reset, the light will
remain flashing.
(i) ABS" Warning Light
The light comes on when the engine
switch 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 malfunctions, the
light comes on again. When the ABS" warning light is on (and
the brake system warning light is off), the
following systems do not operate, but the
brake system still operates conventionally.
Anti−lock brake system
Brake assist system
Traction control system
(two−wheel drive models)
Active traction control system
(four−wheel drive models)
AUTO LSD" system
(two−wheel drive models)
Vehicle stability control system
Downhill assist control system
(four−wheel drive models)
Hill−start assist control system
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 will 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
engine switch is turned to the ON"
position, or remains on.
The light comes on while you are dri-
ving.
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.

159
CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light and low windshield
washer fluid 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. Turn the engine switch to ON", but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light should
come on.
The following service reminder indica-
tors go off after a few seconds:
Engine oil replacement reminder light
ABS" warning light
Tire pressure warning light
RSCA OFF" indicator light
AUTO LSD" indicator light
VSC OFF" indicator/warning light
Slip indicator light
Height control indicator lights
Downhill assist control system indicator
light (four−wheel drive models)
Height control OFF" indicator light
The SRS warning light goes off after
about 6 seconds.
There may be the case that the ABS"
warning light (brake assist system
warning light), AUTO LSD" indicator
light, VSC OFF" indicator/warning light
or slip indicator light stay on for about
60 seconds after the engine switch is
turned to the ON" position. It is nor-
mal 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.

For details about your system’s tone and
balance controls, see the description of
your own system.
Type 1 and 2 audio systems utilize SRS
FOCUS
 and SRS TruBass  audio
enhancement technologies, under license
from SRS Labs, Inc., in all modes except
AM radio mode.

Tone
How good an audio program sounds to
you is largely determined by the mix of
the treble, midrange and bass levels. In
fact, different kinds of music and vocal
programs usually sound better with differ-
ent mixes of treble, midrange and bass. Balance
A good balance of the left and right stereo
channels and of the front and rear sound
levels is also important.
Keep in mind that if you are listening to
a stereo recording or broadcast, changing
the right/left balance will increase the vol-
ume of one group of sounds while de-
creasing the volume of another.
YOUR RADIO ANTENNA
Your vehicle has an antenna printed on
the inside of the rear quarter window.
NOTICE
Putting a film (especially a conductive
or metallic film) on the rear quarter
window will noticeably reduce the
sensitivity of the radio.

346
ANTI−LOCK BRAKE SYSTEM
(with ABS" warning light)
The anti−lock brake system is designed
to help prevent lock−up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional 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 performan-
ce.
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 ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the anti−lock brake sys-
tem activation, the brake pedal may
move a little forward.
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.

347
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 engine
switch 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 malfunctions, the
light comes on again.
When the ABS" warning light is on (and
the brake system warning light is off), the
following systems do not operate, but the
brake system still operates conventionally.
Anti−lock brake system
Brake assist system
Traction control system
(two−wheel drive models)
Active traction control system
(four−wheel drive models)
AUTO LSD" system
(two−wheel drive models)
Vehicle stability control system
Downhill assist control system
(four−wheel drive models)
Hill−start assist control system

348
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 will lock up during a
sudden braking or braking on slippery
road surfaces.
VSC OFF" warning light may flashes with
the ABS" warning light (brake assist sys-
tem warning light) when there is a mal-
function somewhere in the anti−lock brake
system (brake assist system).
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
engine switch is turned to the ON"
position, or remains on.
The light comes on while you are dri-
ving.
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 engine switch is
turned to the ON" position. It is nor-
mal 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).
For an explanation of this system’s warn-
ing light, see Service reminder indicators
and warning buzzers" on page 149 in Sec-
tion 1−6.

HITCHES
If you wish to install a trailer hitch, you
should consult with your Toyota dealer.
Use only a hitch recommended by the
hitch manufacturer and the one which
conforms to the total trailer weight re-
quirement.
According to the hitch receiver type,
the maximum gross trailer weight and
hitch that can be used differs. Refer to
the above illustrations to confirm the
hitch receiver type for your vehicle.
If you wish to install an aftermarket
hitch, the hitch must be bolted securely
to the vehicle frame and installed ac-
cording to the hitch manufactures’ in-
structions.
The hitch ball and king pin should have
a light coat of grease.
Toyota recommends the ball mount as-
sembly be removed when not towing to
prevent injury and to prevent damage
in the event of a rear end collision.
After removing the ball mount assem-
bly, install the grommet to the hitch to
prevent entry of dirt and mud.
CAUTION
Do not tow the vehicle using the
hooked portion of the weight carrying
hitch. The hooked portion may break
and cause serious injury or damage
to the vehicle.
NOTICE
Do not install weight distributing
hitch to weight carrying hitch re-
ceiver because it will be damaged
your vehicle.
 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.

Because stopping distance may be in-
creased, vehicle−to−vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of
speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as
you may skid, resulting in jackknifing
and loss of control. This is especially
true on wet or slippery surfaces.
Avoid jerky starts or sudden accelera-
tion.
Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.
Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this by
making a larger than normal turning
radius with your vehicle.
Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. Steer
straight ahead. If you make no extreme
correction with the steering or brakes,
the vehicle and trailer will stabilize.
Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room befo-
re changing lanes.
In order to maintain engine braking effi-
ciency, do not put the transmission in
D".
Because of the added load of the trail-
er, your vehicle’s engine may overheat
on hot days (at temperatures over
30
C [85 F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to If
your vehicle overheats" on page 394 in
Section 4.
Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in P". Avoid park-
ing on a slope with a trailer, but if it
cannot be avoided, do so only after
performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un- der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, release your brakes slowly until the
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into P" and turn off the engine.
