Part 4
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 procedure 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 starting. See º(c) Jump start-
ingº 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 quali-
fied repair shop.
NOTICE
Do not pull- or push- start the ve- hicle. It may damage the vehicleor cause a collision when the en-
gine starts. Also the three- way
catalytic converter may overheatand become a fire hazard.
If the engine turns over at its nor-
mal speed but will not startÐ
1. Check that all the push- on connec- tors are tight. (For example, con-
nections at the spark plugs, ignition
coil and/or distributor)
2. If the connectors are O.K., the en- gine may be flooded because of
repeated cranking. See º(b) Start-
ing a flooded engineº for further
instructions.
If your vehicle will not start

(a) Simple checks

4RUNNER (1998)
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See Chap-
ter 7- 2 for additional information.
When checking the tires, make sure
no nuts are missing, and check the
nuts for looseness. Tighten them if
necessary.
Tire rotation
Rotate the tires every 12000 km (7500
miles). See Chapter 7- 2 for additional
information.
Fluid leaks
Check underneath for leaking fuel, oil,
water or other fluid after the vehicle
has been parked for a while. If you
smell fuel fumes or notice any leak,
have the cause found and corrected
immediately.
Doors and engine hood
Check that all doors including back
door operate smoothly and all latches
lock securely. Make sure the engine
hood secondary latch secures the
hood from opening when the primary
latch is released. INSIDE THE VEHICLE
Items listed below should be
checked regularly, e.g. while per-
forming periodic services, cleaning
the vehicle, etc.
Lights
Make sure the headlights, stop lights,
tail lights, turn signal lights, and other
lights are all working. Check headlight
aim.
Service reminder indicators and
warning buzzers
Check that all service reminder indica-
tors and warning buzzers function
properly.
Steering wheel
Check that it has the specified free-
play. Be alert for changes in steering
condition, such as hard steering or
strange noise.
Seats
Check that all seat controls such as
seat adjusters, seatback recliner, etc.
operate smoothly and that all latches
lock securely in any position. Check
that the head restraint move up and
down smoothly and that the locks hold
securely in any latched position. For
folding- down rear seatbacks, swing- up
rear seat cushions and detachable
temporary third seat, check that the
latches lock securely.Seat belts
Check that the seat belt system such
as buckles, retractors and anchors op-
erate properly and smoothly. Make
sure the belt webbing is not cut,
frayed, worn or damaged.
Accelerator pedal
Check the pedal for smooth operation
and uneven pedal effort or catching.
Clutch pedal
Check the pedal for smooth operation.
Brake pedal
Check the pedal for smooth operation
and that the pedal has the proper
clearance. Check the brake booster
function.
Brakes
At a safe place, check that the brakes
do not pull to one side when applied.
Parking brake
Check that the lever has the proper
travel and that, on a safe incline, your
vehicle is held securely with only the
parking brake applied.

4RUNNER (1998)
Automatic transmission ºParkº mech- anism
Check the lock release button of the
selector lever for proper and smooth
operation. On a safe incline, check
that your vehicle is held securely with
the selector lever in ºPº 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 addi-
tional information.
Engine coolant level
Make sure the coolant level is be-
tween the ºFULLº and ºLOWº 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
battery cells is between upper and
lower level lines on the case. Add
only distilled water when replenishing.
See Chapter 7- 3 for additional in-
formation. Brake fluid level
Make sure the brake fluid level is cor-
rect. 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 additional information.
Power steering fluid level
Check the level through the reservoir.
The level should be in the ºHOTº or
ºCOLDº 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 immediately. (See engine ex-
haust cautions in Part 2.)
Be on the alert for changes in perfor-
mance, sounds, and visual tip- offs
that indicate service is needed. Some
important clues are as follows:
Engine missing, stumbling, or ping-
ing
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however,
water dripping from the air condi-
tioning after use is normal.)
Change in exhaust sound (This
may indicate a dangerous carbon
monoxide leak. Drive with the win-
dows open and have the exhaust
system checked immediately.)
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 suspen-
sion movement
Loss of brake effectiveness;
spongy feeling brake or clutch ped-
al; pedal almost touches floor; ve-
hicle pulls to one side when brak-
ing
Engine coolant temperature continu-
ally higher than normal
Does your vehicle need
repairing?

4RUNNER (1998)
If you perform maintenance by
yourself, be sure to follow the cor-
rect procedure given in this part.
You should be aware that improper or
incomplete servicing may result in op-
erating problems.
Performing do- it- yourself maintenance
during the warranty period may affect
your warranty coverage. Read the
separate Toyota Warranty statement
for details and suggestions.
This part gives instructions only for
those items that are relatively easy
for an owner to perform. As explained
in Part 6, there are still a number of
items that must be done by a qualified
technician with special tools.
For information on tools and parts for
do- it- yourself maintenance, see ºParts
and toolsº.
Utmost care should be taken when
working on your vehicle to prevent
accidental injury. Here are a few pre-
cautions that you should be especially
careful to observe:
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 ad-
visable.)
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 re-
move the radiator cap or loosen
the drain plugs to prevent burn-
ing yourself.
Do not smoke, cause sparks or
allow open flames around fuel
or the battery. Their fumes are
flammable.
Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
Do not get under your vehicle
with just the body jack support-
ing it. Always use automotive
jack stands or other solid sup-
ports.
Do- it- yourself service
precautions

ENGINE OIL SELECTION Use API grade SH, ºEnergy- Conserv-
ing IIº or SJ, Energy- conservingº
multigrade engine oil or ILSAC multi-
grade 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.

4RUNNER (1998)
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
