4RUNNER (1998)
Part 4
IN CASE OF AN
EMERGENCY
If your vehicle will not start
If your engine stalls while
driving
If your vehicle overheats
If you have a flat tire
If your vehicle needs to be
towed
If you cannot shift automatic
transmission selector lever
If you lose your keys
Before making these checks, make
sure you have followed the correct
starting procedure given in ºHow to
start the engineº in Part 3 and that
you have sufficient fuel.
If the engine is not turning over or
is turning over too slowlyÐ
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the
battery is discharged. You may try
jump starting. See º(c) Jump start-
ingº for further instructions.
If the light is O.K., but the engine still
will not start, it needs adjustment or
repair. Call a Toyota dealer or quali-
fied repair shop.
NOTICE
Do not pull- or push- start the ve- hicle. It may damage the vehicleor cause a collision when the en-
gine starts. Also the three- way
catalytic converter may overheatand become a fire hazard.
If the engine turns over at its nor-
mal speed but will not startÐ
1. Check that all the push- on connec- tors are tight. (For example, con-
nections at the spark plugs, ignition
coil and/or distributor)
2. If the connectors are O.K., the en- gine may be flooded because of
repeated cranking. See º(b) Start-
ing a flooded engineº for further
instructions.
If your vehicle will not start
Ð
(a) Simple checks

4RUNNER (1998)
(b) Starting a flooded engine
If the engine will not start, your
engine may be flooded because of
repeated cranking.
If this happens, turn the key to
ºSTARTº with the accelerator pedal
held down. Keep the key and acceler-
ator pedal so for 15 seconds and re-
lease them. Then try starting the en-
gine with your foot off the accelerator
pedal.
If the engine does not start after 15
seconds of cranking, release the key,
wait a few minutes and try again.
If the engine still will not start, it
needs adjustment or repair. Call a
Toyota dealer or qualified repair shop
for assistance.
NOTICE
Do not crank for more than 30 seconds at a time. This may over-heat the starter and wiring sys-tems.
(c) Jump starting
To avoid serious personal injury
and damage to your vehicle which
might result from battery explosion,
acid burns, electrical burns, or dam-
aged electronic components, these
instructions must be followed pre-
cisely.
If you are unsure about how to follow
this procedure, we strongly recom-
mend that you seek the help of a
competent mechanic or towing service.
CAUTION
Batteries contain sulfuric acid
which is poisonous and corro-
sive. Wear protective safety
glasses when jump starting, and
avoid spilling acid on your skin, clothing, or vehicle.
If you should accidentally get
acid on yourself or in your
eyes, remove any contaminated
clothing and flush the affected
area with water immediately.
Then get immediate medical
attention. If possible, continue
to apply water with a sponge or
cloth while en route to the med-
ical office.
The gas normally produced by
a battery will explode if a flame
or spark is brought near. Use
only standardized jumper cables
and do not smoke or light a
match while jump starting.
NOTICE
The battery used for boosting
must be 12 V. Do not jump startunless you are sure that thebooster battery is correct.

JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make sure the ve-
hicles are not touching. Turn off all
unnecessary lights and accesso-
ries.
2. If required, remove all the vent plugs from the booster and dis-
charged batteries. Lay a cloth over
the open vents on the batteries.
(This helps reduce the explosion
hazard, personal injuries and
burns.)
3. If the engine in the vehicle with the booster battery is not running, start
it and let it run for a few minutes.
During jump starting run the engine
at about 2000 rpm with the accel-
erator pedal lightly depressed.

Connecting point for 5VZ- FE engine
Connecting point for 3RZ- FE engine
Do not connect it to or near any
part that moves when the engine is
cranked.

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.

If towing is necessary, we recom-
mend you to have it done by your
Toyota dealer or a commercial tow
truck service.
If towing service is not available in
an emergency, your vehicle may be
temporarily towed by a cable or
chain secured to the emergency
towing hook. Use extreme caution
when towing vehicles.
A driver must be in the vehicle to
steer it and operate the brakes.
Towing in this manner may be done
only on hard- surfaced roads for a
short distance and at low speeds.
Also, the wheels, axles, drive train,
steering and brakes must all be in
good condition.
CAUTION
Use extreme caution when towing
vehicles. Avoid sudden starts or
erratic driving maneuvers which
would place excessive stress on
the emergency towing hook and
towing cable or chain. The hook
and towing cable or chain may
break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifi-
cally intended for use in towingvehicles. Securely fasten the cableor chain to the towing hook pro-
vided.
Before towing, release the parking
brake and put the transmission in neu-
tral (manual) or ºNº (automatic) and
the transfer in ºH2º (four- wheel drive
models). The key must be in ºACCº
(engine off) or ºONº (engine running).

4RUNNER (1998)
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.
Before emergency towing, check
that the hook is not broken or
damaged and that the installation
bolts are not loose.
Fasten the towing cable or chain
securely to the hook.
Do not jerk the hook. Apply steady
and even force.
To avoid damaging the hook, do
not pull from the side or at a verti-
cal angle. Always pull straight ahead.CAUTION
If the emergency towing eyelet is
used to get out when your vehicle
becomes struck in mud, sand or
other condition from which the
vehicle cannot be driven out un-
der its own power, make sure to
observe the precautions men-
tioned below. Otherwise, exces-
sive stress will be put on the
eyelet and the towing cable or
chain may break, causing serious
injury or damage. If the towing vehicle can hardly
move, do not forcibly continue
the towing. Contact your Toyota
dealer or a commercial tow
truck service for assistance.
Tow the vehicle as straight
ahead as possible.
Keep away from the vehicle
during towing.
