(a) Brake System Warning Light
This light has the following functions:
Parking brake reminder
If this light is on, make sure the parking
brake is fully released. The light should
go off.
Low brake fluid level warning
If this light comes on and stays on while
you are driving, slow down and pull off
the road. Then stop the vehicle carefully.
Remember that stopping distance and ped-
al effort may be increased. There may be
a problem somewhere in the brake sys-
tem. Check the fluid level of the see-
through reservoir.
To make sure the parking brake has not
caused the warning light to come on,
check to see that the parking brake is
fully released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping.
If you judge that the brakes still work
adequately, drive cautiously to your
nearest dealer or shop for repairs.
If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
If the brake fluid level is correct...
Have the warning system checked by your
Toyota dealer.
(b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ºONº or
ºSTARTº, the reminder light and buzzer
come on if the driver's seat belt is not
fastened. Unless the driver fastens the
belt, the light stays on and the buzzer
sounds for about 4 to 8 seconds.
(c) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system. The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(d) Low Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.

Engine exhaust cautions
CAUTION

Avoid inhaling the engine exhaust.
It contains carbon monoxide, which
is a colorless and odorless gas. It
can cause unconsciousness or even
death.
Make sure the exhaust system has
no holes or loose connections. 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 particularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined area
and adjust the heating or cooling
system to force outside air into the
vehicle.
To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open. Have the cause immediately
located and corrected.
Toyota does not recommend occu-
pying the rear cargo area when it
is fitted with a slide-in camper,
camper shell or other type cover
while the engine is running. This
caution applies to both driving and
stopped or parked situations with
the engine running. Particular care
should be taken to prevent exhaust
gases from entering camper bodies,
trailers or other enclosures on or
around your vehicle. If exhaust
fumes are detected, open all win-
dows and thoroughly ventilate the
area.FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining 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 pis-
ton 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 combustion
gases during the combustion process.
Facts about engine oil
consumption

'98 Tacoma (U)143

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 de-
pends 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 become
diluted and make it difficult to judge
the true level accurately.
As an example, if a vehicle is used for
repeated 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
appear 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 it
appear that oil is excessively consumed
after driving at high speeds.
IMPORTANCE OF ENGINE OIL LEVEL CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine troubledue to insufficient oil.
For detailed information on oil level check,
see ºChecking the engine oil levelº in
Chapter 7- 2.
Your engine is fitted with twin ground
electrode spark plugs.
NOTICE
Use only twin ground electrode spark
plugs for your engine performance.

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.

Before emergency towing, check that
the hook is not broken or damaged and
that the installation bolts are not loose.
Fasten the towing cable or chain se-
curely to the hook.
Do not jerk the hook. Apply steady and
even force.
To avoid damaging the hook, do not
pull from the side or at a vertical
angle. Always pull straight ahead.
CAUTION
If the emergency towing hook is used
to get out when your vehicle becomes
stuck in the mud, sand or other
condition from which the vehicle can-
not be driven out under its own pow-
er, make sure to observe the precau-
tions mentioned below. Otherwise, ex-
cessive stress will be put on the
hook and the towing cable or chain
may break, causing serious injury or damage. If the towing vehicle can hardly
move, do not forcibly continue the
towing. Contact your Toyota dealer
or a commercial tow truck service
for assistance.
Tow the vehicle as straight ahead
as possible.
Keep away from the vehicle during
towing.
The following methods are effective to
use when your vehicle is stuck in the
mud, sand or other condition from
which the vehicle cannot be driven out
under its own power. Use extreme cau-
tion when towing the vehicle. In addi-
tion, keep away from the vehicles and
towing cable or chain when towing.
Remove the sand and soil in the front
and the back of the tires.
Place stones or wood under the tires.
