NOTICE
Avoid overfilling, or the engine could be damaged.
Check the oil level on the dipstickonce again after adding the oil.
Engine oil selection
Use API grade SJ, ºEnergy- Conservingº
or ILSAC multigrade engine oil.
Recommended viscosity (SAE):
SAE 5W- 30 is the best choice for your
vehicle, for good fuel economy, and
good starting in cold weather.
If you use SAE 10W- 30 engine oil in
extremely low temperatures, the engine
may become difficult to start, so SAE
5W- 30 engine oil is recommended.
API service symbol
ILSAC certification mark Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SJ. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W- 30. ºEnergy-
Conservingº shown in the lower portion,
indicates that the oil has fuel- saving ca-
pabilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.

Look at the see- through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the ºFº and ºLº lines on the reservoir.
If the level is low, add ethylene- glycol
type coolant for a proper corrosion
protection of aluminum components.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the ºLº line, add
coolant. Bring the level up to the ºFº line.
Always use ethylene- glycol type coolant
for a proper corrosion protection of alumi-
num components. See information in the
next column.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Use of improper coolants may damage
your engine cooling system. Your coolant
must contain ethylene- glycol type coolant
for a proper corrosion protection of your
engine that contains aluminum
components. Use ºToyota Long Life
Coolantº or equivalent.
In addition to preventing freezing and
subsequent damage to the engine, this
type of coolant will also prevent corrosion.
Further supplemental inhibitors or additives
are neither needed nor recommended.
Read the coolant container for information
on freeze protection. Follow the manufac-
turer's directions for how much to mix
with plain water (preferably demineralized
water or distilled water). The total c
apacity
of the cooling system is given in Part 8. We recommend to use 50% solution for
your Toyota, to provide protection down to
about -35
C (- 31 F). When it is extreme-
ly cold, to provide protection down to
about -50 5C (- 58 5F), 60% solution is rec-
ommended. Do not use more than 70%
solution for better coolant performance.NOTICE
Do not use alcohol type antifreeze or
plain water alone.

Checking power steering fluid
If cold add
If cold O.K.
If hot add If hot O.K.
Check the fluid level on the dipstick. If
necessary, add automatic transmission
fluid DEXRON II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (40 5CÐ80 5C or 104 5FÐ175 5F). You
may also check the level when the fluid
is cold (about room temperature,0 5CÐ40 5C or 32 5FÐ104 5F) if the engine
has not been run for about five hours.
a. Clean all dirt from outside of the reser-
voir tank.
b. Remove the filler cap by turning it
counterclockwise and wipe the dipstick
clean. c. Reinstall the filler cap.
d. Remove the filler cap again and look at
the fluid level. If the fluid is cold, the
level should be in the ºCOLDº range on
the dipstick. Similarly, if it is hot, the fluid
level should be in the ºHOTº range. If the
level is at the low side of either range,
add automatic transmission fluid DEXRON
II or III to bring the level within
the range.
e. After replacing the filler cap, visually
check the steering box case, vane pump
and hose connections for leaks or dam- age.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.
Checking tire pressure
Keep your tire pressures at the proper
level.
The recommended cold tire pressures, tire
size and the cargo weight rating are given
in Part 8.
You should check the tire pressures every
two weeks, or at least once a month. And
do not forget the spare!
Incorrect tire pressure can reduce tire
life and make your vehicle less safe to
drive.
Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts from
overheated tires. Also, low tire pressure
can cause poor sealing of the tire bead.
If the tire pressure is excessively low,
there is the possibility of w heel deforma-
tion and/or tire separation.
High tire pressure produces a harsh ride,
handling problems, excessive wear at the
center of the tire tread, and a greater
possibility of tire damage from road haz-
ards.
If a tire frequently needs ref illing, have it
checked by your Toyota dealer.

ÐChecking battery exterior
Ground cable
Terminals
Hold- down
clamp
Check the battery for corroded or loose
terminal connections, cracks, or loose
hold- down clamp.
a. If the battery is corroded, wash it off
with a solution of warm water and baking
soda. Coat the outside of the terminals
with grease to prevent further corrosion.
b. If the terminal connections are loose,
tighten their clamp nutsÐbut do not over-
tighten.
c. Tighten the hold- down clamp only
enough to keep the battery firmly in place.
Overtightening may damage the battery
case.
NOTICE
Be sure the engine and all accesso- ries are off before performing main-tenance.
When checking the battery, remove
the ground cable from the negativeterminal (º- º mark) first and rein-stall it last.
Be careful not to cause a short cir- cuit with tools.
Take care no solution gets into thebattery when washing it.

Battery recharging precautions
During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (5A or less).
Charging at a quicker rate is dan-
gerous. The battery may explode,
causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure allaccessories are turned off.

If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See ºFuse locationsº in Chapter 7- 1 for
locations of the fuses.
Turn the ignition switch and inoperative
component off. Pull a suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
Part 8 of this manual for the functions
controlled by each circuit.

'99 Tacoma (U)

Type A fuses can be pulled out by the
pull- out tool. The location of the pull- out
tool is shown in the illustration.
If you are not sure whether the fuse has
blown, try replacing the suspected fuse
with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an
emergency you can pull out the ºCIGº,
ºRADIOº, ºDOMEº or ºA.Cº fuse, which
may be dispensable for normal driving,
and use it if its amperage rating is the
same.
If you cannot use one of the same amper-
age, use one that is lower, but as close
as possible to the rating. If the amperage
is lower than that specified, the fuse
might blow out again but this does not
indicate anything wrong. Be sure to get
the correct fuse as soon as possible and
return the substitute to its original clip.
It is a good idea to purchase a set of
spare fuses and keep them in your ve-
hicle for emergencies.
If the new fuse immediately blows out,
there is a problem with the electrical sys-
tem. Have your Toyota dealer correct it as
soon as possible.
CAUTION
Never use a fuse with a higher am-
perage rating, or any other object, in
place of a fuse. This may cause ex-
tensive damage and possibly a fire.
Adding washer fluid
If any washer does not work, the wash-
er tank may be empty. Add washer
fluid.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below freezing point, use
washer fluid containing antifreeze. 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.
