CAUTION
To avoid accidentally engaging the
cruise control, turn the system off
when it is not in use. Make sure the
CRUISE" indicator light is off.
CY16059
SETTING THE CRUISING SPEED
The transmission must be in D" or 4"
before you set the cruising speed.
Bring your vehicle to the desired speed,
push the lever down in the − SET" direc-
tion and release it. This sets the vehicle
at that speed. If the speed is not satisfac-
tory, tap the lever up for a faster speed,
or tap it down for a slower speed. Each
tap changes the set speed by 1.6 km/h
(1.0 mph). You can now take your foot off
the accelerator pedal.If you need accelerationfor example,
when passingdepress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE CRUISE CONTROL
The cruise control may be temporarily
cancelled by the driver or by the system
itself under certain circumstances. Tempo-
rary cancellation allows the set cruising
speed to remain in memory.
The cruise control can be temporarily can-
celled by doing the following:
Pulling the lever in the CANCEL" di-
rection and releasing it
Depressing the brake pedal
Under certain circumstances, the cruise
control is temporarily cancelled:
When vehicle speed falls below 40
km/h (25 mph)
When vehicle stability control is acti-
vated
When vehicle speed drops 16 km/h (10
mph) below the set speed, the cruise con-
trol is cancelled and the set speed is
erased from memory.

205
The CRUISE" indicator light remains on
to indicate that the system is still in op-
eration.
To turn the cruise control off, press the
ON−OFF" button. Make sure the
CRUISE" indicator light is off.
If the cruise control automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESUMING THE CRUISE CONTROL
If the cruise control is temporarily can-
celled, the cruising speed can be resumed
by pushing the lever up in the + RES"
direction.
Vehicle speed must be above 40 km/h (25
mph).
RESETTING TO A FASTER SPEED
Push the lever up in the + RES" direction
and hold it. Release the lever when the
desired speed is attained. While the lever
is held up, the vehicle will gradually gain
speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the − SET" direction.RESETTING TO A SLOWER SPEED
Push the lever down in the − SET" direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held down, the vehicle speed will
gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the − SET" direction.
Even if you downshift from D" to 4", with
the cruise control on, engine braking will
not be enabled because the cruise control
is not cancelled. To decrease the vehicle
speed, reset to a slower speed with the
cruise control lever or depress the brake
pedal. If you use the brake pedal, cruise
control is cancelled.
CRUISE CONTROL FAILURE WARNING
If the CRUISE" indicator light flashes
when using the cruise control, press the
ON−OFF" button to turn the system off
and then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.

SECTION 2

345
CY20008a
Your engine is fitted with iridium−tipped
spark plugs.
NOTICE
Use only iridium−tipped spark plugs.
Do not adjust gaps for engine perfor-
mance or smooth driveability.
This brake system has 2 independent hy-
draulic circuits. If either circuit should fail,
the other will still work. However, the ped-
al will be harder to press, and your stop-
ping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses brake fluid pres-
surized by the pump to power−assist the
brakes. If the brake booster fails during
driving, the brake system warning light
comes on and buzzer sounds continuous-
ly. In this case, the brakes may not work
properly. If they do not work well, depress
the brake pedal firmly. If the brake system
warning light comes on, immediately stop
your vehicle and contact your Toyota deal-
er.
It is not a malfunction that the brake sys-
tem warning light may stay on for 60 sec-
onds after the engine switch is turned to
the ON" position.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 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.

349
CY20004
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.Your Toyota is equipped with a limited−slip
center differential (transfer). If one wheel
begins to spin, the limited−slip center dif-
ferential (transfer) is designed to aid trac-
tion by automatically transmitting driving
force to the wheels on the other drive
axle. It transmits driving force to the front
wheels if a rear wheel spins, and to the
rear wheels if a front wheel spins.
CAUTION
Do not start or run the engine while
your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.
NOTICE
Use only a spare tire of the same
brand, size, construction and load ca-
pacity as the original tires on your
Toyota because damage to the limit-
ed−slip differential could possibly oc-
cur with another tire type.
CY20013
The vehicle identification number (VIN)
is the legal identifier for your vehicle.
This number is on the left top of the
instrument panel, and can be seen
through the windshield from outside.
This is the primary identification number
for your Toyota. It is used in registering
the ownership of your vehicle.
