To lock the rear differential, push the switch.
Be sure to stop the wheels before locking
the differential.
Vehicles with manual transmissionÐFor
easy locking, depress the clutch pedal,
push the lock switch and slowly releasethe clutch pedal.
The indicator light will blink when the
switch is turned on. Wait a few seconds for
the system to complete operation. After
the differential is locked, the light will stop
blinking and remain on. The anti-lock brake system does not op-
erate when the rear differential is locked.
It is normal operation for the ABSº warn-
ing light to be on at this time.

Do not lock the differential until
the wheels have stopped spin-
ning. Otherwise, the vehicle may
move in an unexpected direction
when the differential lock is en-
gaged, resulting in an accident.
This may also lead to possible
damage to differential lock com-
ponent parts.
Do not drive over 8 km/h (5 mph)
when the differential is locked. CAUTION
!
To unlock the differential, push the
switch once again.
Unlock the differential as soon as the ve- hicle moves out.
For easy unlocking, slightly turn the steer-
ing wheel in either direction while the ve-hicle is in motion.
When the differential lock is disengaged, the indicator light will go out. The differential will also unlock if you shift
the front drive control lever out of L4º. Never
forget to turn off the switch after us-
ing this feature.
To check the indicator bulb, turn the igni-
tion key to the ONº position, but do not
start the engine.
Do not keep driving with the differ- ential lock switch on. CAUTION
!

83
On vehicles with automatic transmission,
even if you turn off the overdrive switch with the cruise control on, engine braking
will
not be applied because the cruise con-
trol is not cancelled. To decrease the ve-
hicle 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. RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever or by depressing the
brake pedal or clutch pedal, pushing the
lever up in the RES/ACCº direction will
restore the speed set prior to cancellation.
However, once the vehicle speed falls be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
CRUISE CONTROL FAILURE WARN- ING
If the CRUISEº indicator light in the in-
strument cluster flashes when using the
cruise control, press the CRUISE ON-
OFFº 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.
To crank the engine without depress- ing the clutch pedal, push the switch
with the ignition on.
The switch stays on as long as the ignition
is on. And it will automatically turn off
when the ignition is off.
This switch cancels the clutch start sys-
tem, which is designed to keep the starter
motor from operating if the clutch pedal is
not depressed all the way down.
The switch allows the vehicle to be driven
out of difficult situations by cranking the
engine with the clutch engaged.

Types of tires
This vehicle is one of the class of ve-
hicles which have higher ground
clearance and narrower tread in rela-
tion to the height of their center of
gravity to make them capable of per-forming in a wide variety of off-road applications. Specific design charac-
teristics
give it a higher center of gravi-
ty than ordinary cars. An advantage of
the higher ground clearance is a better
view of the road allowing you to antici-
pate problems. It is not designed for
cornering at the same speeds as con-
ventional two-wheel drive vehicles
any more than low-slung sports cars
are designed to perform satisfactorilyunder off-road conditions.
CAUTION!
Always observe the following pre-
cautions to minimize the risk of se-
rious personal injury or damage toyour vehicle: Avoid sharp turns or abrupt ma-
neuvers, if at all possible. As with
other vehicles of this type, failure
to operate this vehicle correctly
may result in loss of control or ve-
hicle rollover.
Avoid loading any items on the
roof that will make the center of
gravity even higher.
Always slow down in gusty cross-
winds. Because of its high center
of gravity, your vehicle is more
sensitive to side winds than an or-
dinary passenger car. Slowing
down will allow you to have much
better control.
Do not drive horizontally across steep slopes. Driving straight up
or straight down is preferred. Your
vehicle (or any similar off-road
vehicle) can tip over sideways
much more easily than forward or backward.

133
Your engine is fitted with twin ground electrode spark plugs.
NOTICE
Use only twin ground electrode spark plugs for your engine perfor-
mance.
TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fa il, the other will still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
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 engine vacuum to
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reservevacuum for one or two stopsÐbut no more!
CAUTION!
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re- serve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder than nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM (with ABSº warning light)
The anti-lock brake system is designed to prevent lock-up of the wheels during sud-
den braking or braking on slippery road surfaces. This assists the driver in con-
trolling the vehicle under these circum-stances.
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).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicleis started. 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 function is in action, you may feel the brake pedal
pulsating and hear a noise. In this situa-
tion, to let the anti-lock brake system work for you, just hold the brake pedal
down
more firmly. Do not pump the brake.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz- ardous road surface conditions. Althoughthe anti-lock brake system assists in pro-
viding vehicle control, it is still important to
drive with all due care, because the anti-
lock brake system cannot overcome the
laws of physics that act on your vehicle: Braking capab ility is dependent on tire
friction with the road surface.
Even though the anti-lock brake sys-
tem is operating, a driver cannot main- tain full control on certain slippery road
surfaces, when cornering at highspeeds, or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot elimi-
nate the risk of hydroplaning and lossof tire friction. Always maintain a safe distance from the
vehicle in
front of you. Compared with ve-
hicles not fitted with an anti-lock brake
system, your vehicle may require a longer
stopping distance in the following cases: Driving on rough, gravel or snow-cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differencesin surface height.
CAUTION!
Do not use tires other than the
manufacturer 's designated tires,
and do not mix tires or wheels of dif-
ferent sizes. You may prevent the an-
tilock brake system from operatingat full effectiveness.
Vehicles with rear differential lock sys-
temÐThe anti-lock brake system does
not operate when the rear differential islocked. It is normal operation for the
ABSº warning light to be on at this time.Type A
Type B

138
CAUTION!
Do not modify the suspension/chas-
sis with lift kits, spacers, springs,
etc. It can cause dangerous handling
characteristics resulting in loss ofcontrol. Determine what kind of tires your ve-
hicle is originally equipped with.
1. Summer tires.
Summer tires are high-speed capability
tires best suited to highway driving underdry conditions. Since
summer tires do not have the same
traction performance as snow tires, sum-
mer tires are inadequate for driving on
snow-covered or icy roads. For driving on
snow-covered or icy roads, we recom-
mend using snow tires. If installing snow tires, be sure to replace all four tires.
2. All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions, as
well as for use all year round.
All season tires, however, do not have ad-
equate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accelera-
tion and handling performance compared with summer tires in highway driving.CAUTION!
Do not mix summer and all season
tires on your vehicle as this can
cause dangerous handling char-
acteristics, resulting in loss of control.
Do not use tires other than the
manufacturer 's designated tires,
and do not mix tires or wheels of
the sizes different from the origi- nals.

1. Check the area around the vehicle be-
fore entering it.
2. Adjust seat position, seatback angle,
seat cushion angle, head restraint height and steering wheel angle.
3. Adjust inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces- sories. 3.
Manual transmission: Press the
clutch pedal to the floor and shift the trans-
mission into neutral. Hold the clutch pedal
to the floor until the engine is started. A
starter safety device will prevent the start-
er from operating if the clutch pedal is not fully depressed.
Automatic transmission: Put the selec-
tor lever in Pº. If you need to restart the
engine while the vehicle is moving, put the
selector lever in Nº. A starter safety de-vice will prevent the starter from operating
if the selector lever is in any drive position. 4. Automatic transmission only: De-
press the brake pedal and hold it to the
floor until driving off.

140Before starting the engine, be sure to fol-
low the instructions in (a) Before crank- ingº.
Normal starting procedure
The multiport fuel injection system/se-
quential multiport fuel injection system in
your engine automatically controls the
proper air-fuel mixture for starting. You can start a cold or hot engine as follows:
1. With your foot off the accelerator ped- al, crank the engine by turning the key to
STARTº. Release it when the enginestarts.
2. After
the engine runs for about 10 sec-
onds, you are ready to drive.
If the weather is below freezing, let the en-
gine warm up for a few minutes before driving.
If the engine stalls...
Simply restart it, using the correct proce- dure given in normal starting. If the engine will not startÐ
See If your vehicle will not startº in Part 4.
NOTICE
Do not crank for more than 15 sec-
onds at a time. This may overheat
the starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult to
start or stalls frequently, have theengine checked immediately.
Always slow down in gusty cross- winds. This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid drivingonto high, sharp-edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.
When parking on a hill, turn the front
wheels until they touch the curb so that
the vehicle will not roll. Apply the park-
ing brake, and place the transmission in Pº (automatic) or in first or reverse
(manual). If necessary, block thewheels.
Washing your vehicle or driving
through deep water may get the
brakes wet. To see whether they are
wet, check that there is no traffic near
you, and then press the pedal lightly. If
you do not feel a normal braking force,
the brakes are probably wet. To dry
them, drive the vehicle cautiously
while lightly pressing the brake pedal
with the parking brake pulled. If they
still do not work safely, pull to the side
of the road and call a T oyota dealer for
assistance.

Four-wheel drive modelsÐToyota
recommends not using four-wheel
drive on dry hard-surfaced roads, be-
cause four-wheel driving will causeunnecessary noise and wear, and poor
fuel economy.
Four-wheel drive modelsÐIn cold
temperatures, noise may occur when
driving in two-wheel drive before the
transfer is warmed up. Therefore, first
drive in four-wheel drive until the
transfer is warmed up.
CAUTION!
Before driving off, make sure that
the parking brake is fully released
and the parking brake reminder
light is off.
Do not leave your vehicle unat- tended while the engine is run-ning.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat
and not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking
on a slippery surface. Sudden ac-
celeration or engine braking, could cause the vehicle to spin or skid.
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high-speed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss of
control and possible injury. Be sure to consult a tire dealer to de-
termine whether the tires on your
vehicle are high-speed capability
tires or not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking
brake will not hold the vehicle se-
curely. When driving your vehicle off-road,
please observe the following precautions
to ensure your driving enjoyment and to
help prevent the closure of areas to off-
road vehicles.
a. Drive your vehicle only in areas where
off-road vehicles are permitted to travel.
b. Respect private property. Get owner's
permission before entering private prop-
erty.
c. Do not enter areas that are closed.
Honor gates, barriers and signs that re-
strict travel.
d. Stay on established roads. When con- ditions are wet, driving techniques should
be changed or travel delayed to prevent
damage to roads.
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off-road, consultthe following organizations.

Off-road driving precautions

142
CAUTION!
Always observe the following pre-
cautions to minimize the risk of seri-
ous personal injury or damage to
your vehicle: Drive carefully when off the road.
Do not take unnecessary risks by
driving in dangerous places.
Do not grip the steering wheel
spokes when driving off-road. A
bad bump could jerk the wheel and
injure your hands. Keep both
hands and especially your thumbs
on the outside of the rim.
Always check your brakes for ef- fectiveness immediately after driv-
ing in sand, mud, water or snow.
After driving through tall grass,
mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper,
rags, stone, sand etc. adhering or
trapped on the underbody. Clear
off any such matter from the under-
body. If the vehicle is used with these materials trapped or adher-
ing to the underbody, a breakdown
or fire could occur.
The driver and all passengers
should fasten their seat belts
whenever the vehicle is moving.
NOTICE
If driving through water, such as
when crossing shallow streams,
first check the depth of the waterand the bottom of the river bed forfirmness. Drive slowly and avoid
deep water.
Take all necessary safety mea-sures to ensure that water damage
to the engine or other components does not occur.
Water entering the engine air in-take will cause severe engine dam-
age.
Water can wash the grease fromwheel bearings, causing rusting
and premature failure, and mayalso enter the differential, trans-
mission and transfer case, reduc- ing the gear oil's lubricating quali-ties.
Sand and mud that has accumu-lated in brake drums and around
brake discs may affect braking ef-ficiency and may damage brakesystem components.
Always perform a maintenance in-
spection after each day of off-road driving that has taken you
through rough terrain, sand, mud, or water. For scheduled mainte-nance information, refer to the
separate Owner's Manual Sup-
plement/Maintenance Scheduleº.
