(a) Simple checks
133
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 lose your keys
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in How 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 (c) Jump startingº for further in- structions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair shop.
NOTICE
Do not pull- or push-start the vehicle. It may damage the vehicle
or cause a collision when the enginestarts. Also the three-way catalytic converter may overheat andbecome a fire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. Check that all the push-on connectors are tight. (For example, connections at the spark plugs, ignition coil and/or dis-
tributor)
2. If the connectors are O.K., the engine may be flooded because of repeated
cranking. See (b) Starting a flooded
engineº for further instructions.

134If the engine will not start, your engine
may be flooded because of repeated cranking.
Turn the key to STARTº with the acceler-
ator pedal held down. Keep the key and accelerator pedal so for 15 seconds and
release
them. Then try starting the engine
with your foot off the accelerator pedal.
If the engine does not start after 15 sec-
onds of cranking, release the key, wait afew minutes and try again.
If the engine still will not start, it needs ad-
justment or repair. Call a Toyota dealer or
qualified repair shop for assistance.
NOTICE
Do not crank for more than 30 sec- onds at a time. This may overheat
the starter and wiring systems.
To avoid serious personal injury and
damage to your vehicle which might
result from battery explosion, acid
burns, electrical burns, or damaged
electronic components, these instruc-
tions must be followed precisely.
If you are unsure about how to follow this procedure, we strongly recommend that you seek the help of a competent me-
chanic or towing service.
Batteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses
when jump starting, and avoid
spilling acid on your skin, cloth-
ing, or vehicle.
If you should accidentally get acid
on yourself or in your eyes, re- move any contaminated clothing
and flush the affected area with water for at least 15 minutes. Then
get immediate medical attention. If
possible, continue to apply water
with a sponge or cloth while en
route to the medical office. CAUTION
!

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 start unless
you are sure that the booster batteryis correct.
JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make sure the ve-
hicles are not touching. T urn off all un-
necessary lights and accessories.
2. If required, remove all the vent plugs from the booster and discharged bat-
teries. Lay a cloth over the open vents
on the batteries. (This helps reduce
the explosion hazard, personal injuries
and burns.)
(b) Starting a flooded engine (c) Jump starting

135
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 accelerator pedal
lightly depressed.
4. Make the cable connection in the ordera, b, c, d.
a. Connect the clamp of the positive (red)
jumper cable to the positive (+) termi-
nal on the discharged battery.
b. Connect the clamp at the other end of the positive (red) jumper cable to the
positive (+) terminal on the booster
battery.c. Connect the clamp of the negative(black) jumper cable to the negative
(-) terminal on the booster battery.
d. Connect the clamp at the other end of the negative (black) jumper cable to a
solid, stationary, unpainted, metallic
point of the ve hicle with the discharged
battery.
The recommended connecting points are
shown in the following illustration:

136
Do not connect the cable to or near any
part that moves when the engine is cranked.
When making the connections, do
not lean over the battery or
accidentally let the jumper cables or
clamps touch anything except the
correct battery terminals or theground. CAUTION
!
5. Start your engine in the normal way. After starting, run it at about 2000 rpm
for several minutes with the accelera- tor pedal lightly depressed.
6. Carefully disconnect the cables in the exact reverse order: the negative
cable and then the positive cable.
7. Carefully dispose of the battery cover clothsÐthey may now contain sulfuricacid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on), you should have it checked. If your engine stalls while driving
0
1. Reduce your speed gradually, keeping
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 If your ve-
hicle will not startº.
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. CAUTION
!
If your engine stalls while driving

137
If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a
loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure 0
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(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 subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine running.
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. CAUTION
! 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 ve-
hicle. However, note that water drain-ing from the air conditioning is normal if it has been used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts. CAUTION
!
4. If the engine drive belt is broken of the coolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as- sistance.
5. If The engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quick-
ly by running it at about 1500 rpm for
a few minutes with the accelerator
pedal lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
Do not attempt to remove the
radiator cap when the engine and
radiator are hot. Serious injury
could result from scalding hot fluid
and steam blown out underpressure. CAUTION
!
7. After the engine coolant temperature has cooled to normal, again check the
coolant level in the reservoir. 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 your vehicle overheats

1381. Reduce
your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from the
traf fic. Avoid stopping on the center di-
vider of a highway. Park on a level spotwith firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in Pº (automatic) or reverse (manual).
4. Have everyone get out of the vehicle on the side away from traffic.
5. Read the following instructions thor- oughly.
When jacking, be sure to observe
the following to reduce the
possibility of personal injury: Follow jacking instructions.
Use the jack only for lifting your
vehicle during wheel changing.
Never get beneath the vehicle
when supported by a jack.
Do not start or run the engine
while your vehicle is supported bya jack. CAUTION
!
NOTICE
Do not continue driving with a deflated tire. Driving even a short
distance can damage a tire beyondrepair.
1. Get the jack, jack handle and wheel nut wrench.
To prepare yourself for an emergency, you should familiarize yourself with the
use of the jack, each of the tools and their storage locations.
If you have a flat tireÐ

When removing the jack, turn the joint by
hand towards the CONTRACT direction
until the jack is free. When storing, turn
the joint by hand towards the EXPAND di-
rection until the jack is firmly secured to
prevent it from flying forward during a col-
lision or sudden braking.To remove the spare tire:
1. Insert the end of the jack handle into the lowering screw and turn it counter- clockwise.
2. After the tire is lowered completely to the ground, remove the holding brack-et.
When storing the spare tire, put it in placewith the outer side of the wheel facing up.
Then secure the tire, taking care that the tire goes straight up without catching on
any other part, to prevent it from flying for-ward during a collision or sudden braking.1. Get the jack and tool bag.
