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.

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

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

4RUNNER (1998)
Use eye protection whenever
you work on or under your ve-
hicle where you may be ex-
posed to flying or falling mate-
rial, fluid spray, etc.
Used engine oil contains poten-
tially harmful contaminants
which may cause skin disorders
such as inflammation or skin
cancer, so care should be taken
to avoid prolonged and repeated
contact with it. To remove 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 filter in household
trash, in sewers or onto the
ground. Call your dealer or a
service station for information
concerning recycling or dispos-
al.NOTICE
Remember that battery and igni-
tion cables carry high currentsor voltages. Be careful of acci-dentally causing a short circuit.
Add only demineralized or dis-tilled water to fill the radiator.And if you spill some of the
coolant, be sure to wash it offwith water to prevent it from
damaging the parts or paint.
Do not allow dirt or anythingelse to fall through the spark
plug holes.
Do not pry the outer electrode
of a spark plug against the cen-ter electrode.
Use only spark plugs of the
specified type. Using othertypes will cause engine damage,loss of performance or radio
noise.
Do not overfill automatic trans-mission fluid, or the transmis-sion could be damaged.
Do not drive with the air clean-
er filter removed, or excessiveengine wear could result. Alsobackfiring could cause a fire in
the engine compartment.
Be careful not to scratch theglass surface with the wiper
frame.
When closing the engine hood,check to see that you have notforgotten any tools, rags, etc.
