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 or the
coolant is leaking, stop the engine immedi-
ately. 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 en-
gine cool down more quickly 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 en- gine is running. Fill it about half full.
Do not attempt to remove the radia-
tor cap when the engine and radia-
tor are hot. Serious injury could re-
sult from scalding hot fluid and
steam blown out under pressure. 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 cool-ant loss indicates a leak in the system.
You should have it checked as soon as
possible at your Toyota dealer. 1. Reduce
your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from the
traffic. Avoid stopping on the center divid-
er of a highway. Park on a level spot with firm ground.
2. Stop the engine and turn on your emer-
gency flashers.
3. Firmly set the parking brake and put the transmission in Pº (automatic) or re- verse (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 possi-
bility of personal injury: Follow jacking instructions.
Use a jack only for lifting your ve-
hicle 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
by a jack. CAUTION
!
NOTICE
Do not continue driving with a deflated tire. Driving even a short
distance can damage a tire beyond repair.
If you have a flat tireÐ

Before towing, release the parking brake
and put the transmission in neutral
(manual) or
Nº (automatic). The key must
be in ACCº (engine off) or ONº (engine 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.
If you cannot shift the selector lever
out of Pº position to other positions
even though the brake pedal is de-pressed, use the shift lock override
button as follows:
1. Turn the ignition key to LOCKº
position. Make sure the parking brakeis on.
2. Pry up the cover with a flat-bladed screwdriver or equivalent.3. Insert the screwdriver or equivalent
into the hole to push down the shift
lock override button. You can shift out of Pº position only while pushing thebutton.
4. Shift into Nº position.
5. Insert the cover.
6. Start the engine. For your safety, keep the brake pedal depressed.
Be sure to have the system checked by
your Toyota dealer as soon as possible.

mance, sounds, and visual tip-offs
that in-
dicate service is needed. Some important
clues are as follows: Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving straight on a level road
Strange noises related to suspensionmovement

When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartmentÐthe engine, radia-
tor, exhaust manifold, power
steering fluid reservoir and spark
plug boots, etc.Ðwill be hot. So be
careful not to touch them. Oil,
fluids and spark plugs may also be
hot.
If the engine is hot, do not remove
the radiator cap or loosen the
drain plugs to prevent burning yourself.
Do not smoke, cause sparks or al-
low open flames around fuel or
the battery. Their fumes are flam- mable.
Be extremely cautious when
working on the battery. It contains
poisonous and corrosive sulfuricacid.
Do not get under your vehicle with
just the body jack supporting it.
Always use automotive jack
stands or other solid supports. CAUTION
!
Be sure that the ignition is off if you
work near the electric cooling fans
or radiator grille. With the ignition
on, the electric cooling fan will au-
tomatically start to run if the engine
coolant temperature is high and/or
the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to fly-
ing or falling material, fluid spray,etc.
Used engine oil contains potential-
ly harmful contaminants which
may cause skin disorders such as
inflammation or skin cancer, so
care should be taken to avoid pro-
longed and repeated contact with
it. To remove used engine oil from
your skin, wash thoroughly with
soap and water.
Do not leave used oil within the reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers
or onto the ground. Call your deal-
er or a service station for informa-
tion concerning recycling or dis- posal.
Remember that battery and igni-
tion cables carry high currents or
voltages. Be careful of accidental-
ly causing a short circuit.
Add only demineralized or dis-tilled water to fill the radiator. And
if you spill some of the coolant, besure to wash it off with water to
prevent it from damaging the
parts or paint.
Do not overfill automatic trans-mission fluid, or the transmission
could be damaged.
Do not drive with the air cleaner fil-ter removed, or excessive enginewear could result. Also backfiringcould cause a fire in the engine
compartment.
Be careful not to scratch the glasssurface with the wiper frame.
When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.
