(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)
Because of the added load of the
trailer, your vehicle's engine may
overheat on hot days (at tempera-
tures over 30 C [85 F]) when go-
ing up a long or steep grade with
a trailer. If the engine coolant tem-
perature gauge indicates overheat-
ing, immediately turn off the air-
conditioning (if in use), pull off the
road and stop in a safe spot. Refer
to ºIf your vehicle overheatsº in
Part 4 of this manual.
Always place wheel blocks under
both the vehicle and trailer wheels
when parking. Apply the parking
brake firmly. Put the transmission
in Pº (automatic) or in first or re-
verse (manual). Avoid parking on a
slope with a trailer, but if it cannot
be avoided, do so only after per-
forming the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks under both the vehicle and trailer
wheels.
3. When the wheel blocks are in place, release your brakes slowly
until the blocks absorb the load.
4. Apply the parking brake firmly. 5. Shift into first or reverse (manual)
or ºPº (automatic) and turn off the
engine. When restarting out after parking on
a slope:
1. With the transmission in ºPº posi- tion (automatic) or the clutch pedal
depressed (manual), start the en-
gine. (With an automatic transmis-
sion, be sure to keep the brake
pedal depressed.)
2. Shift into gear.
3. Release the parking brake (also foot brake on automatic transmis-
sion vehicles) and slowly pull or
back away from the wheel blo cks.
Stop and apply your brakes.
4. Have someone retrieve the blo cks.
CAUTION
Do not exceed 72 km/h (45
mph) or the posted towing
speed limit, whichever is lower.
Because instab ility (swaying) of
a towing vehicle- trailer com-
bination usually increases as
the speed increases, exceeding
72 km/h (45 mph) may cause
loss of control.

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.

4RUNNER (1998)
CAUTION
When making the connections, to
avoid serious injury, do not lean
over the battery or accidentally
let the jumper cables or clamps
touch anything except the correct
battery terminals or the ground.
5. Start your engine in the normal
way. After starting, run it at about
2000 rpm for several minutes with
the accelerator pedal lightly de-
pressed.
6. Carefully disconnect the cables in the exact reverse order: the nega-
tive cable and then the positive
cable.
7. Carefully dispose of the battery cover clothsÐthey may now con-
tain sulfuric acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharg-
ing is not apparent (for example,
lights left on), you should have it
checked. If your engine stalls while driving...
1. Reduce your speed gradually, keep- ing a straight line. Move cautiously
off the road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see ºIf
your vehicle will not startº.
CAUTION
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual.
If your vehicle overheats
If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if
you hear a loud knocking or ping-
ing noise, the engine has probably
overheated. You should follow this
procedure... 1. Pull safely off the road, stop the vehicle and turn on your emergen-
cy flashers. Put the transmission in
ºPº (automatic) or neutral (manual)
and apply the parking brake. Turn
off the air conditioning if it is being
used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the
engine. Wait until the steam sub-
sides before opening the hood. If
there is no coolant boiling over or
steam, leave the engine running.
CAUTION
To help avoid personal injury,
keep the hood closed until there
is no steam. Escaping steam or
coolant is a sign of very high
pressure.
If your engine stalls while
driving

4RUNNER (1998)
3. Visually check to see if the engine drive belt (fan belt) is broken or
loose. Look for obvious coolant
leaks from the radiator, hoses, and
under the vehicle. However, note
that water draining from the air
conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive
belts.
4. If the engine drive belt is brokenor the coolant is leaking, stop the
engine immediately. Call a Toyota
dealer for assistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you
may help the engine cool down
more quickly by running it at about
1500 rpm for a few minutes with
the accelerator pedal lightly de-
pressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir
while the engine is running. Fill it
about half full.
CAUTION
Do not attempt to remove the ra-
diator cap when the engine and
radiator are hot. Serious injury
could result from scalding hot
fluid and steam blown out under
pressure.
7. After the engine coolant tempera-ture has cooled to normal, again
check the coolant level in the res-
ervoir. If necessary, bring it up to
half full again. Serious coolant loss
indicates a leak in the system. You
should have it checked as soon as
possible at your Toyota dealer. If you have a flat tireÐ
1. Reduce your speed gradually, keep- ing a straight line. Move cautiously
off the road to a safe place well
away from the traffic. Avoid stop-
ping on the center divider of a
highway. Park on a level spot with
firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in ºPº (auto-
matic) or reverse (manual).
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.
CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury: Follow jacking instructions.
Do not start or run the engine
while your vehicle is supported
by the jack.

To y o t a
Cleaning the interior
Toyota, through its d iligent research,
design and use of the most advanced
technology available, has done its part
to help prevent corrosion and has pro-
vided you with the finest quality ve-
hicle construction. Now, it is up to
you. Proper care of your Toyota can
help ensure long- term corrosion pre-
vention.
The most common causes of corro-
sion to your vehicle are:
The accumulation of road salt, dirt
and moisture in hard- to- reach
areas under the vehicle.
Chipping of paint, or undercoating
caused by minor accidents or by
stones and gravel.
Care is especially important if you
live in particular areas or operate
your vehicle under certain environ-
mental conditions: Road salt or dust control chemicals
will accelerate corrosion, as will
the presence of salt in the air near
the sea- coast or in areas of indus-
trial pollution.
High humidity accelerates corrosion
especially when temperatures range
just above the freezing point.
Wetness or dampness to certain
parts of your vehicle for an ex-
tended period of time, may cause
corrosion even though other parts
of the vehicle may be dry.
High temperatures will cause corro-
sion to those components of the
vehicle which are prevented from
quick- drying due to lack of proper
ventilation.
The above signifies the necessity to
keep your vehicle, particularly the un-
derside, as clean as possible and to
repair any damage to paint or protec-
tive coatings as soon as possible.
To help prevent corrosion on your
Toyota, follow these guidelines:
Wash your vehicle frequently. It is,
of course, necessary to keep your ve-
hicle clean by regular washing, but to
prevent corrosion, the following points
should be observed:
If you drive on salted roads in the
winter or if you live near the
ocean, you should hose off the un-
dercarriage at least once a month
to minimize corrosion.
Protecting your Toyota
from corrosion

4RUNNER (1998)
High pressure water or steam is
effective for cleaning the vehicle's
underside and wheel housings. Pay
particular attention to these areas
as it is difficult to see all the mud
and dirt. It will do more harm than
good to simply wet the mud and
debris without removing them. The
lower edge of doors, rocker panels
and frame members have drain
holes which should not be allowed
to clog with dirt as trapped water
in these areas can cause corro-
sion.
Wash the underside of the vehicle
thoroughly when winter is over.
See ºWashing and waxing your Toyo-
taº for more tips.
Check the condition of your ve-
hicle's paint and trim. If you find any
chips or scratches in the paint, touch
them up immediately to prevent corro-
sion from starting. If the chips or
scratches have gone through the bare
metal, have a qualified body shop
make the repair. Check the interior of your vehicle.
Water and dirt can accumulate under
the floor mats and could cause corro-
sion. Occasionally check under the
mats to make sure the area is dry. Be
particularly careful when transporting
chemicals, cleansers, fert
ilizers, salt,
etc; these should be transported in
proper containers. If a spill or leak
should occur, immediately clean and
dry the area.
Use mud shields on your wheels. If
you drive on salted or gravel roads,
mud shields help protect your vehicle.
Full- size shields, which come as near
to the ground as possible, are the
best. We recommend that the fittings
and the area where the shields are
installed be treated to resist corrosion.
Your Toyota dealer will be happy to
assist in supplying and insta lling the
shields if they are recommended for
your area.
Keep your vehicle in a well venti-
lated garage or a roofed place. Do
not park your vehicle in a damp,
poorly ventilated garage. If you wash
your vehicle in the garage, or if you
drive it in covered with water or snow,
your garage may be so damp it will
cause corrosion. Even if your garage
is heated, a wet vehicle can corrode
if the ventilation is poor. Washing your Toyota
Keep your vehicle clean by regular
washing.
The following cases may cause weak-
ness to the paint or corrosion to the
body and parts. Wash your vehicle as
soon as possible.
When driving in a coastal area
When driving on a road sprinkled
with antifreeze
When having stuck of coal tar, tree
sap, bird droppings and carcass of
an insect
when driving in the areas where
there are a lot of smoke, soot,

Cleaning the interior
CAUTION
Do not wash the vehicle floor
with water, or allow water to get
onto the floor when cleaning the
vehicle interior or exterior. Water
may get into audio components
or other electrical components
above or under the floor carpet
(or mat) and cause a malfunction;
and it may cause body corrosion.
Vinyl interior
The vinyl upholstery may be easily
cleaned with a mild soap or deter-
gent and water.
First vacuum over the upholstery to
remove loose dirt. Then, using a
sponge or soft cloth, apply the soap
solution to the vinyl. After allowing it
to soak in for a few minutes to loosen
the dirt, remove the dirt and wipe off
the soap with a clean damp cloth. If
all the dirt does not come off, repeat
the procedure. Commercial foaming-
type vinyl cleaners are also available
which work well. Follow the manufac-
turer's instructions.
NOTICE
Do not use solvent, thinner, gaso- line or window cleaner on the in-terior.
Carpets
Use a good foam- type shampoo to
clean the carpets.
Begin by vacuuming thoroughly to re-
move as much dirt as possible. Sever-
al types of foam cleaners are avail-
able; some are in aerosol cans and
others are powders or liquids which
you mix with water to produce a foam.
To shampoo the carpets, use a
sponge or brush to apply the foam.
Rub in overlapping circles.
Do not apply waterÐthe best results
are obtained by keeping the carpet as
dry as possible. Read the shampoo
instructions and follow them closely.
Seat belts
The seat belts may be cleaned with
mild soap and water or with luke-
warm water.
Use a cloth or sponge. As you are
cleaning, check the belts for exces-
sive wear, fraying, or cuts.
NOTICE
Do not use dye or bleach on the
beltsÐit may weaken them.
Windows
The windows may be cleaned with
any household window cleaner.
NOTICE
When cleaning the inside of thewindows, be careful not toscratch or damage the heaterwires on the rear window.
Air conditioning control panel, car
audio, instrument panel, console
panel, and switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or
lukewarm water then lightly wipe off
any dirt.
