(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.

YOUR CASSETTE PLAYER
When you insert a cassette, the ex-
posed tape should be to the right.
NOTICE
Do not oil any part of the player
and do not insert anything otherthan cassette tapes into the slot,or the tape player may be dam-
aged.
YOUR COMPACT DISC PLAYER
When you insert a disc, gently push
it in with the label side up. (The play-
er will automatically eject a disc if the
label side is down.) The compact disc
player will play from track 1 through
the end of the disc. Then it will play
from track 1 again.
NOTICE
Never try to disassemble or oilany part of the compact disc play-er. Do not insert anything except
a compact disc into the slot.
8 cm (3 in.) compact disc singles
Your compact disc player does not
need an adaptor to play compact disc
singles. Compact disc singles are
about 8 cm (3 in.) in diameter- smaller
than standard di scs.
After you eject a compact disc single,
do not insert a standard 12 cm (5 in.)
disc until ºDISCº disappears from the
display.
NOTICE
Do not use an adaptor for com- pact disc singles
'it could cause
tracking errors or interfere with the ejection of compact discs.

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

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.

4RUNNER (1998)
Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps pre-
vent corrosion.
Keep your vehicle tuned- up and
in top shape. A dirty air cleaner,
improper valve clearance, dirty
plugs, dirty oil and grease, brakes
not adjusted, etc. all lower engine
performance and contribute to poor
fuel economy. For longer life of all
parts and lower operating costs,
keep all maintenance work on
schedule, and if you often drive
under severe conditions, see that
your vehicle receives more frequent
maintenance (For scheduled main-
tenance information, please refer to
the separate ºOwner 's Manual Sup-
plement/Maintenance Scheduleº).
CAUTION
Never turn off the engine to coast
down hills. Your power steering
and brake booster will not func-
tion without the engine running.
Also, the emission control system
operates properly only when the
engine is running.
