Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps prevent
corrosion.

Keep your vehicle tuned-up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For lon-
ger 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 ve-
hicle receives more frequent mainte-
nance (For scheduled maintenance in-
formation, please refer to the separate
Owner 's Manual Supplement/Main-
tenance Scheduleº).
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function
without the engine running. Also,
the emission control system
operates properly only when the
engine is running.!

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

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 pullÐ or push-start the vehicle. It may damage the vehicle
or cause a collision when the enginestarts. Also the three-way catalyticconverter 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, connectors 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.

152If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the key to STARTº
with the accelerator 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 a
few 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 seconds at a time. This may
overheat the starter and wiringsystems.
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 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 you 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 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.)
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 (+)
terminal 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) cable to the negative (-) termi-
nal 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 point is
shown in the following illustration:
ProCarManuals.com

154
Do not connect it to or near any part that
moves when the engine is cranked.
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.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 sulfuric
acid.
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 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 and make sure the electric
cooling fan is operating. If it is not, turn
the ignition off.
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. 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 coolant is leaking, stop the en-
gine immediately. Call a Toyota dealer
for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine 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 under
pressure. CAUTION
!
6. 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

1561. 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 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 Pº.
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.

Do not start or run the engine
while your vehicle is supported
by the jack. CAUTION
!


Stop the vehilce at a level place
and chock the wheel diagnonally
opposite to the one being
changed. Otherwise, the vehicle
will move and possibly cause un-
expected accident.

Make sure to set the jack properly
in the jack point. Raising the ve-
hicle with jack improperly posi-
tioned will damage the vehicle or
may allow the vehicle to fall off the
jack and cause injury to the per-
son.

Never get under the vehicle when
the vehicle is supported by the
jack alone.

Use the jack only for lifting your
vehicle during wheel changing.

Do not raise the vehicle with some-
one in the vehicle.

When raising the vehicle, do not
put an object on or under the jack.
NOTICE
Do not continue driving with a deflated tire. Driving even a short
distance can damage a tire beyondrepair.
1. Get the required tools and spare tire.
1. Tool bag
2. Jack
3. Jack handle
4. Spare tire
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 towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed by a cable or chain se-
cured to either emergency towing eye-
let under the vehicle. 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 dis-
tance 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 eyelet and
towing cable or chain. The eyelets
and towing cable or chain may
break and cause serious injury or
damage.
NOTICE
Use only a cable or chain specifically intended for use in
towing vehicles. Securely fasten the
cable or chain to the towing eyelets provided.
Before towing, release the parking brake
and put the transmission in Nº. The key
must be in ACCº (engine off) or ONº (en-
gine running).
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.

ber.
See the suggestion given in Keysº in
Chapter 1-2.
If your keys are locked in the vehicle and
you cannot get a duplicate, many Toyota
dealers
can still open the door for you, us-
ing their special tools. If you must break a
window to get in, we suggest breaking the
smallest side window because it is the
least expensive to replace. Be extremely
cautious to avoid cuts from the glass. If you lose your transmitter, you can
purchase a new one at your Toyota
dealer.
You can use the wireless remote control
system with the new transmitter. Contact
your Toyota dealer for detailed informa-
tion.
