3. Hold the hood open by insertingthe support rod into the slot.
Before closing the hood, check to see that
you have not forgotten any tools, rags,
etc. and return the support rod to its clip-
this prevents rattles. Then lower the hood
and make sure it locks into place. If neces-
sary, press down gently on front edge to lock it.
After inserting the support rod into
the slot, make sure the rod supports
the hood security.
CAUTION!
1. To open the fuel filler door, pull the
lever up.
CAUTION!
Do not smoke, cause sparks or al-
low open flames when refuelling.
The fumes are flammable.
When opening the cap, do not re-
move the cap quickly. In hot weath-
er, fuel under pressure could cause
injury by spraying out of the filler
neck if the cap is suddenly re- moved.
Do not fill a fuel container on a plas-
tic truck bed liner, a rubber truck
bed mat, or any other insulating
material. A static electricity charge
could cause a spark and fire haz-
ard. The proper procedure is to
place an approved fuel container
on the ground away from the truckfor filling.

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 hi
gher center or grav-
ity than ordinary cars. An advantage ofthe 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 conditions.
CAUTION!
Always obeserve the following pre-
cautions to minimize the risk of seri-
ous personal injury or damage to
your vehicle: Avoid sharp turns or abrupt maneu-
vers, if at all possible. As with other
vehicles of this type, failure to oper-
ate this vehicle correctly may result
in loss of control or vehicle rol-
lover.
Avoid l oading 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 sensi-
tive to side winds than an ordinary
passenger car. Slowing down will
allow you to have much better con- trol.
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.

Your engine is fitted with twin ground electrode spark plugs.
Use only twin ground electrodespark plugs for your engine
performance.
NOTICE
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 stops - but 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 hard-much harder than
normal. And your braking dis- tance 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 pro-
viding directional stability and steering per -
formance of the vehicle under these cir -
cumstances.
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 approximate-
ly 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.

IN CASE OF AN EMERGENCY
If your vehicle will not start
If your engine stalls while driving
If your vehicle overheats
If you have a flat tire
If your vehicle needs to be towed
If you cannot shift automatic
transmission selector lever
If you lose your keys
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in How to start the engineº
in Part 3 and that you have sufficient fuel.
If the engine is not turning over or is
turning over too slowlyÐ
1. Check that the battery terminals are
tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the battery is
discharged. You may try jump starting.
See (c) Jump startingº for further in- structions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair shop.
NOTICE
Do not pull- or push-start the vehicle. It may damage the vehicle
or cause a collision when theengine starts. Also the three-way catalytic converter may overheatand become a fire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. Check that all the push-on connectors are tight. (For example, connections at the spark plugs, ignition coil and/or dis-
tributor)
2. If the connectors are O.K., the engine may be flooded because of repeated
cranking. See (b) Starting a flooded
engineº for further instructions.

140If the engine will not start, your engine
may be flooded because of repeated cranking.
If this happens, turn the key to STARTº with the accelerator pedal held down.
Keep
the key and accelerator pedal so for
15 seconds and release them. Then try
starting the engine with your foot off the accelerator pedal.
If the engine does not start after 15 sec-
onds of cranking, release the key, wait a few minutes and try again.
If the engine still will not start, it needs ad-
justment or repair. Call a Toyota dealer or
qualified repair shop for assistance.
NOTICE
Do not crank for more than 30 sec- onds at a time. This may overheat
the starter and wiring systems.
To avoid serious personal injury and
damage to your vehicle which might
result from battery explosion, acid
burns, electrical burns, or damaged
electronic components, these instruc-
tions must be followed precisely.
If you are unsure about how to follow this procedure, we strongly recommend that you seek the help of a competent me-
chanic or towing service.
Batteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses
when jump starting, and avoid
spilling acid on your skin, cloth-
ing, or vehicle.
If you should accidentally get acid
on yourself or in you eyes, remove
any contaminated clothing and
flush the affected area with water
immediately. Then get immediate
medical attention. If possible, con-
tinue to apply water with a sponge
or cloth while en route to the medi- cal office. CAUTION
!

The gas normally produced by a battery will explode if a flame or
spark is brought near. Use only
standardized jumper cables and
do not smoke or light a match
while jump starting.
NOTICE
The battery used for boosting must be 12 V. Do not jump start unless
you are sure that the booster batteryis correct.
JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make sure the ve-
hicles are not touching. T urn off all un-
necessary lights and accessories.
2. If required, remove all the vent plugs from the booster and discharged bat-
teries. Lay a cloth over the open vents
on the batteries. (This helps reduce
the explosion hazard, personal injuries
and burns.)

When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartmentÐthe engine, radia-
tor, exhaust manifold, power
steering fluid reservoir and spark
plug boots, etc.Ðwill be hot. So
be careful not to touch them. Oil,
fluids and spark plugs may also be
hot.
If the engine is hot, do not remove
the radiator cap or loosen the
drain plugs to prevent burning yourself.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flamable.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
Do not get under your vehicle with
just the body jack supporting it.
Always use automotive jack
stands or other solid supports. CAUTION
!
Use eye protection whenever you
work on or under you vehicle
where you may be exposed to fly-
ing or falling material, fluid spray, etc.
Used engine oil contains poten-
tially harmful contaminants which
may cause skin disorders such as
inflammation or skin cancer, so
care should be taken to avoid pro-
longed and repeated contact with
it. To remove used engine oil from
your skin, wash thoroughly with
soap and water.
Do not leave used oil within thereach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers
or onto the ground. Call your deal- er or a service station for informa-
tion concerning recycling or dis- posal.
Remember that battery and igni-
tion cable carry high currents or
voltages. Be careful of accidental-
ly causing a short circuit.
Add only demineralized or dis- tilled w ater to fill the radiator. And
if you spill some of the coolant, be sure to wash it off with water to
prevent it from damaging theparts or paint.
Do not allow dirt or anything elseto fall through the spark plug
holes.
Do not pry the outer electrode of aspark plug against the center elec-
trode.
Use only spark plugs of the speci- fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
Do not overfill automatic trans- mission fluid, or the transmission
could be damaged.
Do not drive with the air cleaner fil-ter removed, or excessive enginewear could result. Also backfiring
could cause a fire in the enginecompartment.
