TURNING ON THE SYSTEM
To operate the cruise control, push the
CRUISE ON-OFFº switch. This turns the system on. The indicator light in the instru-
ment panel shows that you can now set
the vehicle at a desired cruising speed. Another push will turn the system com-
pletely off.
To avoid accidental cruise control
engagement, keep the CRUISE
ON-OFFº switch off when not using
the cruise control. CAUTION
!
SETTING AT A DESIRED SPEED
On vehicles with automatic transmission,
the transmission must be in Dº beforeyou set the cruise control speed.
Bring your vehicle to the desired speed, push the lever down in the SET/COASTº
direction and release it. This sets the ve-
hicle at
that speed. If the speed is not sat-
isfactory, 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 acceleration Ð for example,
when passingÐdepress the accelerator
pedal
enough for the vehicle to exceed the
set speed. When you release it, the ve-
hicle will return to the speed set prior to the
acceleration.
For manual transmission:
While driving with the cruise control
on, do not shift to neutral without
depressing the clutch pedal, as this
may cause engine racing or overrev-ing. CAUTION
!
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the lever in the CANCELº di- rection and releasing it.
b. Depressing the brake pedal.
c. Depressing the clutch pedal (manual transmission).
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto- matically cancel out.
If the vehicle speed drops 16 km/h (10 mph) below the preset speed, the preset speed will also automatically cancel out.

85
If the preset speed automatically cancels
out other than for the above cases or, if the
indicator light flashes several times, the
cruise control may be malfunctioning. In such
cases, have your vehicle checked by
your Toyota dealer at the earliest opportu-
nity.
RESETTING AT A FASTER SPEED Push the lever up in the RES/ACCº direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held up, the vehicle will graduallygain speed.
However, a faster way to reset is to accel-
erate the vehicle and then push the lever down in the SET/COASTº direction.
RESETTING AT A SLOWER SPEED Push the lever down in the SET/COASTº
direction and hold it. Release the lever
when the desired speed is attained. While
the lever is held down, the vehicle speedwill gradually decrease.
However, a faster way to reset is to de- press the brake pedal and then push the
lever down in the SET/COASTº direction.
On vehicles with automatic transmission,
even if you turn off the overdrive switchwith 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.

CIGARETTE LIGHTER
To use the cigarette lighter, press it in.
When it becomes heated, it automati-
cally pops out ready for use.
If the engine is not running, the key must be in the ºACCº position.
Do not hold the cigarette lighter pressed in.
Use a Toyota genuine cigarette lighter or equivalent for replacement.ASHTRAY
To use the ashtray, open the cover. When finished with your cigarette, thor-
oughly extinguish it in the ashtray to pre-
vent other cigarette butts from catching
fire. After using the
ashtray, close the ash-
tray cover completely.
To remove the ashtray, open the ashtray cover and pull it out.To reduce the chance of injury in
case of an accident or sudden stop
while driving, always close the ash-
tray cover completely after using. CAUTION
!
To use the glovebox, do this.
To open: Pull the lever.
To lock: Insert the master key and turn it clockwise.
To reduce the chance of injury in
case of an accident or sudden stop,
always keep the glovebox door
closed while driving.CAUTION

Suspension and chassis
Types of tires
This vehicle is one of the class of ve-
hicles which have higher ground
clearances 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 satisfactorily under off-road condtions.
CAUTION!
Always observe the following pre-
cautions to minimize the risk of se-
rious personal injury or damage toyour vehicle: Avoid loading any items on the
roof that will make the center of
gravity even higher.
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.
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 passsenger car. Slowing
down will allow you to have much
better control.

108
Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your ve-
hicle (or any similar off-road ve-
hicle) can tip over sideways much
more easily than forward or back- ward.
When driving off-road or in rugged
terrain, do not drive at excessive
speeds, jump the vehicle, or strike
objects, etc. This may cause loss or
control or vehicle rollover. You are
also risking expensive damage to
your vehicle's suspension and chassis. Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break-in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of your vehicle:
Do not drive over 88 km/h (55 mph).
Run the engine at moderate speed be- tween 2000 and 4000 rpm.
Avoid full-throttle starts.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive slowly with the manual
transmission in a high gear.
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles) FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups, your
Toyota has a new smaller fuel tank open- ing.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
Do not use leaded gasoline. Use of
leaded gasoline will cause the
three-way catalytic converter tolose its effectiveness and the emis- sion control system to function im-properly. Also, this can increase maintenance costs.
NOTICE
OCTANE NUMBER
Select Research Octane Number 91
(Octane Rating 87) or higher.
Use of unleaded fuel with an octane num- ber rating lower than stated above will
cause persistent heavy knocking. If se-
vere, this will lead to engine damage.
Break-in period
Fuel

109
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady sp
eed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no needof concern.
GASOLINES CONTAINING DETER-
GENT ADDITIVES
Toyota recommends use of gasolines
that contain detergent additives to
avoid buld-up of engine deposits.
For further details, ask your Toyota dealer
or a local gasoline retailer.
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Methyl
Tertiary-Butyl Ether) are available in
the market. If you use a gasoline mixed
with MTBE, make certain that it does
not contain more than 15% of MTBE.
If the use of gasolines containing MTBE causes poor driveability and/or poor fuel
economy, you should discontinue the use
of fuels containing MTBE. If you use gasohol in your Toyota, be sure
that it is
unleaded, has an octane rating no
lower than 87 and does not contain more than 10% ethanol.
Gasohol is a mixture of gasoline and etha-
nol.
Toyota does not recommend the use of
gasolines containing methanol. If you use
gasoline containing methanol, use only
gasoline meeting the requirements above
and also containing less than 5% metha-
nol with cosolvents and corrosion inhibi-
tors for methanol.

Do not use gasohol other thanstated above. It will cause fuel
system damage or vehicle perfor-
mance problems.
If driveability problems occur(poor hot starting, vaporizing, en-
gine knock, etc), discontinue theuse.
Take care not to spill gasohol dur-
ing refueling. Gasohol may causepaint damage.

11 0If you plan to drive your Toyota in
another country... First,
comply with the vehicle registration
laws. Second, confirm the availability of the
correct fuel (unleaded and minimum oc- tane number).
The three-way catalytic converter is
an emission control device installed in
the exhaust system.
The purpose is to reduce pollutants in the exhaust gas.
CAUTION!
Keep people and combustible materials away from the exhaust
pipe while the engine is running. The exhaust gas is very hot.
Do not drive, idle or park your ve-
hicle over anything that might
burn easily such as grass, leaves,
paper or rags.
A large amount of unburned gases
flowing into the three-way catalytic
converter may cause it to overheatand create a fire hazard. To prevent this and other damage, observe thefollowing precautions:
Use only unleaded gasoline.
Do not drive with an extremely lowfuel level; running out of fuelcould cause the engine to misfire,
creating an excessive load on the
three-way catalytic converter.
Do not allow the engine to run atidle speed for more than 20 min-utes.
Avoid racing the engine.
Do not push-start or pull-start
your vehicle.
Do not turn off the ignition whilethe vehicle is moving.
NOTICE
Three-way catalytic converter
Operation in foreign countries

111

Keep
your engine in good running
order. Malfunctions in the engine
electrical system, electronic igni-tion system/distributor ignitionsystem or fuel systems could
cause an extremely high three-
way catalytic converter tempera-ture.
If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check-up as soon
as possible. Remember, your To-
yota dealer knows your vehicleand its three-way catalytic con-
verter system best.
To ensure that the three-way cata-lytic converter and the engine
emission control system operate
properly, your vehicle must re-ceive the periodic inspections re-
quired by the Toyota Maintenance
Schedule. For scheduled mainte- nance information, refer to the
separate Owner's Manual Sup- plement/Maintenance Scheduleº.
CAUTION!
Avoid inhaling the engine ex-
haust. It contains carbon monox-
ide, which is a colorless and odor-
less gas. It can cause uncon-
sciousness or even death.
Make sure the exhaust system
has no holes or loose connec-
tions. The system should be
checked from time to time. If you
hit something, or notice a change
in the sound of the exhaust, have
the system checked immediately.
Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot escape, making this a paticularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine
running. If it is unavoidable, how-
ever, do so only in an unconfined
area and adjust the heating or
cooling system to force outside air into the vehicle.Keep the back door closed while
driving. An open or unsealed back door may cause exhaust gases to be drawn into the ve-
hicle. If you must drive with theback door open to accommodate a large object, close the windows,
open all the instrument panel vents and have the heating or
cooling system deliver fresh air
into the vehicle by turning the fan
to high speed with the air intake
control lever set at the outside air position.
To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the
windshield clear of snow, leaves, or other obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the back door closed.
Have the cause immediately lo- cated and corrected.

11 2FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lu-
bricating and cooling the inside of the en-
gine,
and plays a major role in maintaining
the engine in proper working order. ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are
as follows. Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil is left on the cylinder wall when a piston
moves downwards in the cylinder.
High negative pressure generated
when the vehicle is decelerating sucks
some of this oil into the combustion
chamber. This oil as well as some part
of the oil film left on the cylinder wall is
burned by the high temperature com-
bustion gases during the combustionprocess.
Oil is also used to lubricate the stems
of the intake valves. Some of this oil is
sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-perature exhaust gases also burn the
oil used to lubricate the exhaust valve stems.
The amount of engine oil consumed
depends on the viscosity of the oil, the
quality of the oil and the conditions
the vehicle is driven under. More oil is consumed by high-speed driv-
ing and frequent acceleration and decel- eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, note that the oil may be-come diluted and make it difficult to
judge the true level accurately.
As an example, if a vehicle is used for re-
peated short trips, and consumes a nor- mal amount of oil, the dipstick may not
show any drop in the oil level at all, even after 1000 km (600 miles) or more. This is because the oil is gradually becoming
diluted
with fuel or moisture, making it ap-
pear that the oil level has not changed.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making itappear that oil is excessively consumed
after driving as high speeds.
IMPORTANCE OF ENGINE OIL LEVEL CHECK
One of the most important points in proper vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will not be impaired. Therefore, it is essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level bechecked every time you refuel the vehicle.
Failure to check the oil level regular-
ly could lead to serious engine
trouble due to insufficient oil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.

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 reserve vacuum for one or two stopsÐbut nomore!
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 normal. And your braking
distance will be longer.
ANTI-LOCK BRAKE SYSTEM (with ABSº warning light)
The anti-lock brake system is designed to
automatically help prevent lock-up of the
wheels during sudden braking or braking on slippery road surfaces. This assists in
providing directional stability and steeringperformance of the vehicle under these circumstances.
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 vehicle is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the ABSº 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 pumpthe brake. This will result in reduced
braking performance.
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.
