When driving your vehicle off-road, please
observe the following precautions to en-
sure 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 proper-
ty.
c. Do not enter areas that are closed.
Honor gates, barriers and signs that re-
strict travel.
d. Stay on established roads. When condi-
tions 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, consult
the following organizations.
State and Local Parks and Recreation
Departments
State Motor Vehicle Bureau
Recreational Vehicle Clubs
U.S. Forest Service and Bureau of
Land Management
CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle: 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 effec-
tiveness immediately after driving 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 adhering
to the underbody, a breakdown or
fire could occur.
The driver and all passengers
should fasten their seat belts when-
ever 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 for
firmness. Drive slowly and avoiddeep water.
Take all necessary safety measures
to ensure that damage to the en-gine or other components does notoccur.
Water entering the engine air intakewill cause severe engine damage.
Water can wash the grease fromwheel bearings, causing rusting and
premature failure, and may also en-ter the differentials, transmission and transfer case, reducing the gear
oil's lubricating qualities.
Off-road driving pr ecautions
(four-wheel drive models only)

'98 Tacoma (U)155

Sand and mud that has accumulated
in brake drums and around brakediscs may affect braking efficiency and may damage brake system com-
ponents.
Always perform a maintenance in-spection after each day of off-road
driving that has taken you throughrough terrain, sand, mud, or water.For scheduled maintenance informa-
tion, refer to the separate ºOwner'sManual Supplement/MaintenanceScheduleº.
Winter driving tips
Make sure you have ethylene-glycol an-
tifreeze in the radiator.
NOTICE
Do not use alcohol type antifreeze.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Chapter 7- 3 tells you how to visually
inspect the battery. Your Toyota dealer
and most service stations will be pleased
to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Chapter 7- 2 for recommended viscos-
ity. Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealer±
he will be pleased to help.
Keep the door locks from freezing.
Squirt lock de-icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before
inserting it. Use a washer fluid containing an anti-
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer 's directions for how
much to mix with water.NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-age your vehicle's paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
ºPº (automatic) or into first or reverse
(manual) and block the front wheels. Do
not use the parking brake, or snow or
water accumulated in and around the
parking brake mechanism may freeze,
making it hard to release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.

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 ºHow 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 start-
ing. See º(c) Jump startingº for further
instructions.
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 causea collision when the engine starts. Also the three-way catalytic converter
may overheat and become a fire haz-ard.
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, connectors 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 º(b) Starting a flooded
engineº for further instructions.

If your vehicle overheats
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in ºPº
(automatic) or neutral (manual) and ap-
ply the parking brake. Turn off the air
conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Visually check to see if the engine drive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or thecoolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as-
sistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperaturehas cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Toyota dealer.

Automatic transmission ºPark'' mecha-
nism
Check the lock release button of the se-
lector lever (floor shift type) for proper
and smooth operation. On a safe incline,
check that your vehicle is held securely
with the selector lever in ºP'' position and
all brakes released.
IN THE ENGINE COMPARTMENT
Items listed below should be checked
from time to time, e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7- 3 for additional in-
formation.
Engine coolant level
Make sure the coolant level is between
the ºFULL'' and ºLOW'' lines on the see-
through reservoir when the engine is cold.
See Chapter 7- 2 for additional information.
Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower lev-
el lines on the case. Add only distilled
water when replenishing. See Chapter 7- 3
for additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See Chapter 7- 2 for additional information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See Chapter 7- 2 for addi-
tional information.
Power steering fluid level
Check the level on the dipstick. The level
should be in the ºHOT'' or ºCOLD'' range
depending on the fluid temperature. See
Chapter 7- 2 for additional information.
Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.)
Be on the alert for changes in perfor-
mance, sounds, and visual tip-offs that
indicate service is needed. Some impor-
tant clues are as follows:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving
straight on a level road
Strange noises related to suspension
movement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continually
higher than normal
Does your vehicle need
repairing?

CAUTION
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, radiator,
exhaust manifold, power steering
fluid reservoir and spark plug
boots, etc.Ðwill be hot. So be care-
ful 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 flammable.
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. Al-
ways use automotive jack stands or
other solid supports.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach 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 dealer or
a service station for information
concerning recycling or disposal.NOTICE
Remember that battery and ignition
cables carry high currents or volt-ages. Be careful of accidentallycausing a short circuit.
Add only demineralized or distilled water to fill the radiator. And if youspill some of the coolant, be sure
to wash it off with water to preventit from damaging the parts or paint.
Do not allow dirt or anything elseto fall through the spark plug holes.
Do not pry the outer electrode of a
spark plug against the center elec-trode.
Use only spark plugs of the speci-fied type. Using other types willcause engine damage, loss of per-
formance or radio noise.
Do not overfill automatic transmis-sion fluid, or the transmissioncould be damaged.
Do not drive with the air cleaner
filter removed, or excessive enginewear could result. Also backfiringcould cause a fire in the engine
compartment.
