(a) Brake System Warning Light
This light has the following functions:
Parking brake reminder
If this light is on, make sure the park-
ing 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 ve-
hicle carefully. There may be a prob-
lem somewhere in the brake system.
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
starting and stopping.
If you judge that the brakes still
work adequately, drive cautiously to
your nearest dealer or shop for re-
pairs.
If the brakes are not working, have
the vehicle towed in for repairs.
(For towing information, see Part
4.)CAUTION
It is dangerous to continue driv-
ing 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 keeps
on flickering 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
operate, however, until the battery is
discharged. Turn off the air condition-
ing, blower, radio, etc., and drive di-
rectly to the nearest Toyota dealer or
repair shop.
NOTICE
Do not continue driving if the en- gine drive belt is broken or loose.
(d) Low Oil Pressure Warning Light
This light warns that the engine oil
pressure 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 immediate-
ly. 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 ac-
celerated slightly.
The light may come on when the oil
level is extremely low. It is not de-
signed to indicate low oil level, and
the oil level must be checked using
the level dipstick.
NOTICE
Do not drive the vehicle with thewarning light onÐeven for oneblock. It may ruin the engine.

4RUNNER (1998)
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.
Facts about engine oil
consumption

4RUNNER (1998)
The diluting ingredients evaporate out
when the vehicle is then driven at
high speeds, as on an expressway,
making it appear that oil is excessive-
ly consumed after driving at high
speeds.
IMPORTANCE OF ENGINE OIL LEV-
EL CHECK
One of the most important points in
proper vehicle maintenance is to keep
the engine 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 rec-
ommends that the oil level be checked
every time you refuel the vehicle.
NOTICE
Failure to check the oil level regu-
larly could lead to serious enginetrouble due to insufficient oil.
For detailed information on oil level
check, see ºChecking the engine oil
levelº in Chapter 7- 2. Twin ground electrode spa

4RUNNER (1998)
The driver and all passengers
should fasten their seat belts
whenever the vehicle is moving.
NOTICE
If driving through water, such
as when crossing shallowstreams, first check the depth of the water and the bottom of
the river bed for firmness. Driveslowly and avoid deep water.
Take all necessary safety mea-
sures to ensure that water dam-age to the engine or other com- ponents does not occur.
Water entering the engine airintake will cause severe engine
damage.
Water can wash the grease fromwheel bearings, causing rustingand premature failure, and mayalso enter the differentials,
transmission and transfer case,reducing the gear oil's lubrica-ting qualities.
Sand and mud that has accum-
lated in brake drums andaround brake discs may affectbraking efficiency and may dam-
age brake system components.
Always perform a maintenanceinspection after each day of
off- road driving that has takenyou through rough terrain,sand, mud, or water. For sche-
duled maintenance information,refer to the separate ºOwner's Manual Supplement/Maintenance
Scheduleº.
Winter driving tips
Make sure you have ethylene- glycol
antifreeze in the radiator.
NOTICE
Do not use alcohol type anti-freeze.
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 starting. 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
viscosity. 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 dealerÐhe 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.

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
