1998 TOYOTA 4RUNNER check engine

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

Even if the power assist is
completely lost, the brakes will
still work. But you will have to
push the pedal hardÐmuch
harder than normal. And your
braking distance will be longer.
ANTI- LOCK BRAKE SYSTEM
(with ºABSº warning light)
The anti- lock brake system is de-
signed to automatically help prevent
lock- up of the wheels during sudden
braking or braking on slippery road
surfaces. This assists in providing
directional stab ility and steering per-
formance of the vehicle under these
circumstances.
The anti- lock brake system becomes
operative after the vehicle has accel-
erated to a speed in excess of
approximately 10 km/h (6 mph). It
stops operating when the vehicle de-
celerates to a speed below approxi-
mately 5 km/h (3 mph).
You may hear a sound in the engine
compartment for a few seconds when
the engine is started or just after the
vehicle is started. This means that the
anti- lock brake system is in the self
check mode, and does not indicate a
malfunction. Effective way to press the ºABSº
brake pedal: When the anti- lock brake
system function is in action, you may
feel the brake pedal pulsating and
hear a noise. In this situation, to let
the anti- lock brake system work for
you, just hold the brake pedal down
more firmly. Do not pump the brake.
This will result in reduced braking per-
formance.
The brake pedal pulsation caused by
the anti- lock brake system may indi-
cate hazardous road surface condi-
tions. Although the anti- lock brake
system assists in providing vehicle
control, it is still important to drive
with all due care, because the anti-
lock brake system cannot overcome
the laws of physics that act on your
vehicle:
Braking capab ility is dependent on
tire friction with the road surface.
Even though the anti- lock brake
system is operating, a driver can-
not maintain full control on certain
slippery road surfaces, when cor-
nering at high speeds, or in violent
maneuvers.
Avoid high speeds on wet roads.
The anti- lock brake system cannot
eliminate the risk of hydroplaning
and loss of tire friction. Always maintain a safe distance from
the vehicle in front of you. Compared
with vehicles not fitted with an anti-
lock brake system, your vehicle may
require a longer stopping distance in
the following cases:
Driving on rough, gravel or snow-
covered roads.
Driving with tire chains installed.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
CAUTION
Do not use tires other than the
manufacturer 's designated tires,
and do not mix tires or wheels of
different sizes. You may prevent
the antilock brake system from
operating at full effectiveness.
Vehicles with rear differential lock sys-
tem 'The anti- lock brake system does
not operate when the rear differential
is locked. It is normal operation for
the ºABSº warning light to be on at
this time.

Before starting the engine
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, seat cushion angle, head re-
straint height and steering wheel
angle.
3. Adjust inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and ac-
cessories.
3. Manual transmission: Press the
clutch pedal to the floor and shift
the transmission into neutral. Hold
the clutch pedal to the floor until
the engine is started. A starter
safety device will prevent the start-
er from operating if the clutch ped-
al is not fully depressed.
Automatic transmission: Put the
selector lever in ºPº. If you need to
restart the engine while the vehicle
is moving, put the selector lever in
ºNº. A starter safety device will pre-
vent the starter from operating if the
selector lever is in any drive position.
4. Automatic transmission only: De-
press the brake pedal and hold it
to the floor until driving off.
How to start the engineÐ
(a) Before cranking

4RUNNER (1998)
(b) Starting the engine
Before starting the engine, be sure to
follow the instructions in º(a) Before
crankingº.
Normal starting procedure
The multiport fuel injection system/se-
quential multiport fuel injection system
in your engine automatically controls
the proper air- fuel mixture for starting.
You can start a cold or hot engine as
follows:
1. With your foot off the accelerator
pedal, crank the engine by turning the
key to ºSTARTº. Release it when the
engine starts.
2. After the engine runs for about 10
seconds, you are ready to drive.
If the weather is below freezing, let
the engine warm up for a few minutes
before driving.
If the engine stalls...
Simply restart it, using the correct
procedure given in normal starting.
If the engine will not startÐ
See ºIf your vehicle will not startº in
Part 4.
NOTICE
Do not crank for more than 30 seconds at a time. This mayoverheat the starter and wiringsystems.
Do not race a cold engine.
If the engine becomes difficult
to start or stalls frequently,have the engine checked im-mediately.
Always slow down in gusty cross-
winds. This will allow you much
better control.
Drive slowly onto curbs and, if
possible, at a right angle. Avoid
driving onto high, sharp- edged ob-
jects and other road hazards. Fail-
ure to do so can lead to severe
tire damage resulting in tire bursts.
When parking on a hill, turn the
front wheels until they touch the
curb so that the vehicle will not
roll. Apply the parking brake, and
place the transmission in ºPº (auto-
matic) or in first or reverse (manu-
al). If necessary, block the wheels.
Washing your vehicle or driving
through deep water may get the
brakes wet. To see whether they
are wet, check that there is no
traffic near you, and then press the
pedal lightly. If you do not feel a
normal braking force, the brakes
are probably wet. To dry them,
drive the vehicle cautiously while
lightly pressing the brake pedal
with the parking brake pulled. If
they still do not work safely, pull to
the side of the road and call a
Toyota dealer for assistance.
Tips for driving in various
conditions

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.

4RUNNER (1998)
Use a washer fluid containing an
antifreeze solution.
This product is available at your Toyo-
ta dealer and most auto parts stores.
Follow the manufacturer 's directions
for how much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because itmay damage your vehicle's paint.
Do not use your parking brake
when there is a possibility it could
freeze.
When parking, put the transmission
into ºPº (automatic) or into first or
reverse (manual) and block the rear
wheels. Do not use the parking brake,
or snow or water accumulated in and
around the parking brake mechanism
may freeze, making it hard to release.
Keep ice and snow from accumulat-
ing under the fenders.
Ice and snow built up under your
fenders can make steering difficult.
During bad winter driving, stop and
check under the fenders occasionally. Depending on where you are driv-
ing, we recommend you carry some
emergency equipment.
Some of the things you might put in
the vehicle are tire chains, window
scraper, bag of sand or salt, flares,
small shovel, jumper cables, etc.
Trailer towing
Your vehicle is designed primarily as
a passenger- and- load- carrying ve-
hicle. Towing a trailer will have an
adverse effect on handling, perfor-
mance, braking, durability and driving
economy (fuel consumption, etc.).
Your safety and satisfaction depend
on the proper use of correct equip-
ment and cautious driving habits. For
your safety and the safety of others,
you must not overload your vehicle or
trailer. Ask your local Toyota dealer
for further details before towing.
WEIGHT LIMITS
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, gross
axle weight and trailer tongue load
are all within the limits.
The total trailer weight and tongue
load can be measured with platform
scales found at a highway weighing
station, building supply company,
trucking company, junk yard, etc.

4RUNNER (1998)
A safety chain must always be
used between the towing vehicle
and the trailer. Leave sufficient
slack in the chain for turns. The
chain should cross under the
trailer tongue to prevent the
tongue from dropping to the
ground in case it becomes dam-
aged or separated. For correct
safety chain procedures, follow
the hitch or trailer manufactur-
er 's recommendations.
CAUTION
If the total trailer weight ex-
ceeds 453 kg (1000 lb.), trailer
brakes are required .
Never tap into your vehicle's
hydraulic system as it would
lower its braking effectiveness .
Never tow a trailer without us-
ing a safety chain securely atta-
ched to both the trailer and the
vehicle. If damage occurs to the
coupling unit or hitch ball,
there is danger of the trailer
wandering over into another
lane.
TIRES
Ensure that your vehicle's tires are
properly inflated. See Chapter 7- 2
for instructions.
The trailer tires should be inflated
to the pressure recommended by
the trailer manufacturer in respect
to the total trailer weight.
TRAILER LIGHTS Trailer lights must comply with fed-
eral, state/provincial and local re-
gulations. See your local recre-
ational vehicle dealer or rental
agency for the correct type of wir-
ing and relays for your trailer.
Check for correct operation of the
turn signals and stop lights each
time you hitch up. Direct splicing
may damage your vehicle's electri-
cal system and cause a malfunc-
tion of your lights.
BREAK- IN SCHEDULE Toyota recommends that you do
not tow a trailer with a new vehicle
or a vehicle with any new power
train component (engine, transmis-
sion, differential, wheel bearing,
etc.) for the first 800 km (500
miles) of driving. MAINTENANCE
If you tow a trailer, your vehicle
will require more frequent
maintenance due to the additional
load. For this information, please
refer to the scheduled maintenance
information in the ºOwner 's Manual
Supplement/Maintenance Scheduleº.
Retighten all fixing bolts of the
towing ball and bracket after
approximately 1000 km (600 miles)
of trailer driving.
PRE- TOWING SAFETY CHECK
Check that your vehicle remains
level when a loaded or unloaded
trailer is hitched. Do not drive if
the vehicle has an abnormal nose-
up or nose- down condition, and
check for improper tongue load,
overload, worn suspension or other
possible causes.
Make sure the trailer cargo is se-
curely loaded so that it cannot
shift.
Check that your rear view mirrors
conform to any applicable federal,
state/provincial or local regulation.
If not, install the rear view mirrors
required for towing purpose.

4RUNNER (1998)
TRAILER TOWING TIPS
When towing a trailer, your vehicle
will handle differently than when
not towing. The three main causes
of vehicle- trailer accidents are driv-
er error, excessive speed and im-
proper trailer loading. Keep these in
mind when towing:
Before starting out, check operation
of the lights and all vehicle- trailer
connections. After driving a short
distance, stop and recheck the
lights and connections. Before ac-
tually towing a trailer, practice turn-
ing, stopping and backing with a
trailer in an area away from traffic
until you learn the feel.
Backing with a trailer is difficult
and requires practice. Grip the bot-
tom of the steering wheel and
move your hand to the left to move
the trailer to the left. Move your
hand to the right to move the trail-
er to the right. (This procedure is
generally opposite to that when
backing without a trailer). Also, just
turn the steering wheel a little at
a time, avoiding sharp or prolonged
turning. Have someone guide you
when backing to reduce the risk of
an accident.
Because stopping distance may be
increased, vehicle- to- vehicle dis-
tance should be increased when
towing a trailer. For each 16 km/h
(10 mph) of speed, allow at least
one vehicle and trailer length bet-
ween you and the vehicle ahead.
Avoid sudden braking as you may
skid, resulting in jackknifing and
loss of control. This is especially
true on wet or slippery surfaces.
Avoid jerky starts or sudden accel-
eration. If your vehicle has a
manual transmission, prevent ex-
cessive clutch slippage by keeping
engine rpm low and not racing the
engine. Always start out in first
gear.
Avoid jerky steering and sharp
turns. The trailer could hit your ve-
hicle in a tight turn. Slow down
before making a turn to avoid the
necessity of sudden braking.
Remember that when making a
turn, the trailer wheels will be clos-
er than the vehicle wheels to the
inside of the turn. Therefore, com-
pensate for this by making a larger
than normal turning radius with y-
our vehicle.
Crosswinds and rough roads will
adversely affect handling of your
vehicle and trailer, causing sway.
Pay attention to the rear from time
to time to prepare yourself for be-
ing passed by large trucks or
buses, which may cause your ve-
hicle and trailer to sway. If swaying
happens, firmly grip the steering
wheel and reduce speed immedi-
ately but gradually. Never increase
speed. Steer straight ahead. If you
make no extreme correction with
the steering or brakes, the vehicle
and trailer will stabilize.
Be careful when passing other ve-
hicles. Passing requires consider-
able distance. After passing a ve-
hicle, do not forget the length of
your trailer and be sure you have
plenty of room before changing
lanes.
In order to maintain engine braking
efficiency, do not use fifth gear
(manual transmission) or overdrive
(automatic transmission).
