4RUNNER (1998)
(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)
Your engine is fitted with twin
ground electrode spark plugs.
NOTICE
Use only twin ground electrode
spark plugs for your engine per-formance.
Brake system
TANDEM MASTER CYLINDER
BRAKE SYSTEM
The tandem master cylinder brake
system is a hydraulic system with two
separate sub- systems. If either sub-
system s hould fail, the other will still
work. However, the pedal will be hard-
er to press, and your stopping dis-
tance will be longer. Also, the brake
system warning light may come on.
CAUTION
Do not drive your vehicle with
only a single brake system. Have
your brakes fixed immediately.
BRAKE BOOSTER The brake booster uses engine vacu-
um to power- assist the brakes. If the
engine should quit while you are driv-
ing, you can bring the vehicle to a
stop with normal pedal pressure.
There is enough reserve vacuum for
one or two stopsÐbut no more!
CAUTION

Do not pump the brake pedal if
the engine stalls. Each push on
the pedal uses up your vacuum
reserve.

4RUNNER (1998)
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.

4RUNNER (1998)
The brake pad wear limit indicators
on your disc brakes give a warning
noise when the brake pads are
worn to where replacement is re-
quired.
If you hear a squealing or scraping
noise while driving, have the brake
pads checked and replaced by your
Toyota dealer as soon as possible.
Expensive rotor damage can result if
the pads are not replaced when nec-
essary. Luggage stowage pr
ecau-
tions
When stowing luggage or cargo in the
vehicle, observe the following:
Put luggage or cargo in the lug-
gage compartment when at all pos-
sible. Be sure all items are se-
cured in place.
Be careful to keep the vehicle bal-
anced. Locating the weight as far
forward as possible helps maintain
balance.
For better fuel economy, do not
carry unneeded weight.
CAUTION
To prevent luggage or packages
from sliding forward during
braking, do not stack anything
in the luggage compartment
higher than the seatbacks. Keep
luggage or packages low, as
close to the floor as possible.
Never allow anyone to ride in
the luggage compartment. It is
not designed for passengers.
They should ride in their seats
with their seat belts properly
fastened. Otherwise, they are
much more likely to suffer seri-
ous bodily injury, in the event
of sudden braking or a colli-
sion.

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)
Four- wheel drive modelsÐToyota
recommends not using four- wheel
drive on dry hard- surfaced roads,
because four- wheel driving will
cause unnecessary noise and wear,
and poor fuel economy.
Four- wheel drive modelsÐIn cold
temperatures, noise may occur
when driving in two- wheel drive
before the transfer is warmed up.
Therefore, first drive in four- wheel
drive until the transfer is warmed up.CAUTION
Before driving off, make sure
that the parking brake is fully
released and the parking brake
reminder light is off.
Do not leave your vehicle unat-
tended while the engine is run-
ning.
Do not rest your foot on the
brake pedal while driving. It can
cause dangerous overheating,
needless wear, and poor fuel
economy.
To drive down a long or steep
hill, reduce your speed and
downshift. Remember, if you
ride the brakes excessively,
they may overheat and not work
properly.Be careful when accelerating,
upshifting, downshifting or
braking on a slippery surface.
Sudden acceleration or engine
braking, could cause the vehicle
to spin or skid.
Do not drive in excess of the
speed limit. Even if the legal
speed limit permits it, do not
drive over 140 km/h (85 mph)
unless your vehicle has
high- speed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss
of control and possible injury.
Be sure to consult a tire dealer
to determine whether the tires
on your vehicle are high- speed
capability tires or not before
driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they
are wet, your vehicle will re-
quire a longer stopping dis-
tance, and it may pull to one
side when the brakes are ap-
plied. Also, the parking brake
will not hold the vehicle secure-
ly.

4RUNNER (1998)
When driving your vehicle off- road,
please observe the following precau-
tions to ensure your driving enjoyment
and to help prevent the closure of
areas to off- road vehicles.
a. Drive your vehicle only in areas
where off- road vehicles are permitted
to travel.
b. Respect private property. Get own-
er's permission before entering private
property.
c. Do not enter areas that are closed.
Honor gates, barriers and signs that
restrict travel.
d. Stay on established roads. When
conditions are wet, driving techniques
should be changed or travel delayed
to prevent damage to roads.
For owners in U.S. mainland, Hawaii
and Puerto Rico:
To obtain additional information per-
taining to driving your vehicle off-
road, consult the following organiza-
tions. State and Local Parks and Recre-
ation Departments
State Motor Vehicle Bureau
Recreational Vehicle Clubs
U.S. Forest Service and Bureau of
Land Management
CAUTION
Always observe the following pre-
cautions to minimize the risk of
serious personal injury or damage
to your vehicle: Drive carefully when off the
road. Do not take unnecessary
risks by driving in dangerous
places.
Do not grip the steering wheel
spokes when driving off- road. A
bad bump could jerk the wheel
and injure your hands. Keep
both hands and especially your
thumbs on the outside of the
rim.
Always check your brakes for
effectiveness immediately after
driving in sand, mud, water or
snow.
After driving through tall grass,
mud, rock, sand, rivers, etc.,
check that there is no grass,
bush, paper, rags, stone, sand,
etc. adhering or trapped on the
underbody. Clear off any such
matter from the underbody. If
the vehicle is used with these
materials trapped or adhering to
the underbody, a breakdown or
fire could occur.Off- road driving precaution

Total trailer weight
Tongue load
Tongue load
Total trailer weight
100 9 to 11 %
The trailer cargo load should be
distributed so that the tongue
load is 9 to 11% of the total
trailer weight, not exceeding the
maximum of the following. Nev-
er load the trailer with more
weight in the back than in the
front. About 60% of the trailer
load should be in the front half
of the trailer and the remaining
40% in the rear.
3RZ- FE engine158 kg (350 lb.)
5VZ- FE engine 226 kg (500 lb.)HITCHES
Use only a weight carrying hitch
designed for the total trailer weight.
Toyota does not recommend using
a weight distribution (load equaliz-
ing) hitch.
The hitch must be bolted securely
to the vehicle frame and installed
according to the hitch manufactur-
er 's instructions.
The hitch ball and king pin should
have a light coat of grease.
Toyota recommends removing the
hitch when not towing to preventin-
jury and/or damage due to the
hitch in event of a rear end colli-
sion. After removal of the hitch,
seal the installation area to prevent
entry of exhaust fumes and mud.
NOTICE
Do not use an axle- mounting
hitch as it may cause damage tothe axle housing, wheel bearings,wheels and or tires.
BRAKES AND SAFETY CHAINS
Toyota recommends trailers with
brakes that conform to any appli-
cable federal and state/provincial
regulations.

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).
