CAUTION
Do not smoke, cause sparks or
allow open flames when refuel-
ing. The fumes are flammable.
When opening the cap, do not
remove the cap quickly. In hot
weather, fuel under pressure
could cause injury by spraying
out of the filler neck if the cap
is suddenly removed.
2. To remove the fuel tank cap, turn
the cap slowly counterclockwise,
then pause slightly before remov-
ing it. After removing the cap,
hang it on the cap hanger. It is not unusual to hear a slight
swoosh when the cap is opened.
When installing, turn the cap clock-
wise till you hear a click.
If the cap is not tightened securely,
the malfunction indicator lamp comes
on. Make sure the cap is tightened
securely. 0The indicator lamp goes off after
driving several times. If the indicator
lamp does not go off, contact your
Toyota dealer as soon as possible.

Keep the back door and back
window closed while driving. An
open or unsealed back door and
back window, may cause ex-
haust gases to be drawn into
the vehicle. If you must drive
with the trunk lid open to ac-
commodate a large object, close
the windows, open all the
instrument panel vents and
have the heating or cooling sys-
tem deliver fresh air into the
vehicle by turning the fan to
high speed with the air intake
control set at the outside air
position.
To allow proper operation of
your vehicle's ventilation sys-
tem, keep the inlet grilles in
front of the windshield clear of
snow, leaves, or other obstruc-
tions.
If you smell exhaust fumes in
the vehicle, drive with the win-
dows open and the back door
and back window closed. Have
the cause immediately located
and corrected.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
maintaining the engine in proper work-
ing order.
ENGINE OIL CONSUMPTION
It is normal that an engine should
consume some engine oil during
normal engine operation. The
causes of oil consumption in a nor-
mal 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 down-
wards in the cylinder. High nega-
tive 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 cylin-
der wall is burned by the high tem-
perature combustion gases during
the combustion process.
Oil is also used to lubricate the
stems of the intake valves. Some
of this oil is sucked into the com-
bustion chamber together with the
intake air and is burned along with
the fuel. High temperature 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 condi-
tions the vehicle is driven under.
More oil is consumed by high- speed
driving and frequent acceleration and
deceleration.
A new engine consumes more oil,
since its pistons, piston rings and cyl-
inder walls have not become condi-
tioned.
When judging the amount of oil
consumption, 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 normal 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.

Slow down and downshift be-
fore descending steep or long
downhill grades. Do not make
sudden downshifts.
Avoid holding the brake pedal
down too long or too frequent-
ly. This could cause the brakes
to overheat and result in re-
duced braking efficiency.Getting more kilometers/mileage from
a liter/gallon of fuel is easyÐjust take
it easy. It will help make your vehicle
last longer, too. Here are some specif-
ic tips on how to save money on both
fuel and repairs:
Keep your tires inflated at the
correct pressure. Underinflation
causes tire wear and wastes fuel.
See Chapter 7- 2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts
a heavier load on the engine, caus-
ing greater fuel consumption.
Avoid lengthy warm- up idling.
Once the engine is running smooth-
ly, begin drivingÐbut gently. Re-
member, however, that on cold win-
ter days this may take a little
longer.
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into
high gear as quickly as possible.
Avoid long engine idling. If you
have a long wait and you are not
in traffic, it is better to turn off the
engine and start again later.
Avoid engine lug or overrevving.
Use a gear position suitable for the
road on which you are travelling.
Avoid continuous speeding up
and slowing down. Stop- and- go
driving wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace.
Try to time the traffic signals so
you only need to stop as little as
possible or take advantage of
through streets to avoid traffic
lights. Keep a proper distance from
other vehicles to avoid sudden
braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic
jams whenever possible.
Do not rest your foot on the
clutch or brake pedal. This
causes needless wear, overheating
and poor fuel economy.
Maintain a moderate speed on
highways. The faster you drive,
the greater the fuel consumption.
By reducing your speed, you will
cut down on fuel consumption.
Keep the front wheels in proper
alignment. Avoid hitting the curb
and slow down on rough roads.
Improper alignment not only causes
faster tire wear but also puts an
extra load on the engine, which, in
turn, wastes fuel.

The top portion of the label shows the
oil quality by API (American Petroleum
Institute) designations such as SJ.
The center portion of the label shows
the SAE
viscosity grade such as SAE 5W- 30.
ºEnergy- Conservingº shown in the
lower portion, indicates that the oil
has fuel- saving capab ilities.
The ILSAC (International Lubricant
Standardization and Approval Commit-
tee) Certification Mark is displayed on
the front of the container. Look at the see- through coolant
reservoir when the engine is cold.
The coolant level is satisfactory if
it is between the ºF (Full)º and ºL
(Low)º lines on the reservoir. If the
level is low, add ethylene- glycol
type coolant.
The coolant level in the reservoir will
vary with engine temperature. Howev-
er, if the level is on or below the ºLº
line, add coolant. Bring the level up
to the ºFº line.
Use only ethylene- glycol type coolant.
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 engine is hot.
Coolant type selection
Your coolant must contain ethylene-
glycol antifreeze. In addition to pre-
venting freezing and subsequent dam-
age to the engine, this will also
prevent corrosion. Further supplemen-
tal inhibitors or additives are neither
needed nor recommended.
Read the antifreeze container for in-
formation on freeze protection. Follow
the manufacturer 's directions for how
much to mix with water. The total ca-
pacity of the cooling system is given
in Part 8. We recommend 50% solu-
tion be used for your Toyota, or a
sufficient quantity to provide protection
to about -35
C (- 31 F).
NOTICE
Do not use alcohol type antifreeze
or plain water alone.
Checking the engine coolan
level

4RUNNER (1998)
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
economy, and the possib ility of blow-
outs 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 possi-
bility of w heel deformation 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 dam-
age from road hazards.
If a tire frequently needs ref illing,
have it checked by your Toyota deal-
er. The following instructions for
checking tire pressure should be
observed:
The pressure should be checked
only when the tires are cold. If
your vehicle has been packed for
at least 3 hours and has not been
driven for more than 1.5 km or 1
mile since, you will get an accurate
cold tire pressure reading.
Always use a tire pressuregauge. The appearance of a tire
can be misleading. Besides, tire
pressures that are even just a few
pounds off can degrade handling
and ride.
Do not bleed or reduce tire pres-
sure after driving. It is normal for
the tire pressure to be higher after
driving.
Never exceed the vehicle capac-
ity weight. The passenger and lug-
gage weight should be located so
that the vehicle is balanced.
Be sure to reinstall the tire infla-
tion valve caps. Without the valve
caps, dirt or moisture could get
into the valve core and cause air
leakage. If the caps have been
lost, have new ones put on as
soon as possible. Checking and replacing tires
