If your vehicle overheats
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in ºPº
(automatic) or neutral (manual) and ap-
ply 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.
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.
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 broken or thecoolant 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 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
engine is running. Fill it about half full.
CAUTION
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.
7. After the engine coolant temperaturehas cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Toyota dealer.

If you have a flat tireÐ
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
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 (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.
CAUTION
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.
Stop the vehicle on a level firm
ground, firmly set the parking brake
and put the transmission in Pº
(automatic) or reverse (manual).
Block the wheel diagonally opposite
to the one being changed if neces-
sary.
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 personal injury.
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.
Raise the vehicle only high enough
to remove and change the tire.NOTICE
Do not continue driving with a de-
flated tire. Driving even a short dis-tance can damage a tire beyond re- pair.

Compact spare tire
The compact spare tire is designed for
temporary emergency use only.
The compact spare tire is identified by the
distinctive wheel design and color and
special wording ºTEMPORARY USE ONLYº
molded into the side wall of the tire.
The standard tire should be repaired and
replaced as soon as possible.
To keep the compact spare tire noticeable,
do not hide the wheel by a wheel cover
or such. The compact spare tire saves space in
your luggage compartment, and its lighter
weight helps to improve fuel economy and
permits easier installation in case of a flat
tire.
The compact spare tire can be used many
times, if necessary. It has tread life of up
to 4800 km (3000 miles) depending on
road conditions and your driving habits.
When tread wear indicators appear on the
tire, replace the tire.
See also the tire section in Chapter 7- 2
for details on the tread wear indicators
and other service information.
CAUTION

The compact spare tire was de-
signed especially for your Toyota.
Do not use it on any other vehicle.
Do not exceed 80 km/h (50 mph)
when driving with the compact
spare tire.
Avoid sudden acceleration, sudden
deceleration and sharp turns with
the compact spare tire.
NOTICE
Your ground clearance is reduced
when the compact spare tire isinstalled so avoid driving over ob- stacles and drive slowly on rough,
unpaved roads and speed bumps.Also, do not attempt to go through anautomatic car wash as the vehicle
may get caught, resulting in damage.

ÐRequired tools and spare tire
1. Get the wheel nut wrench, jack, jack
handle and spare tire.
To prepare yourself for an emergency, you
should fam iliarize yourself with the use of
the jack, each of the tools and their stor-
age locations.To remove the jack, loosen the bolt and
remove it.
When storing the jack, secure it by follow-
ing removal step in reverse order to pre-
vent it from flying forward during a colli-
sion or sudden braking.To remove the spare tire:
1. Remove the spare tire cover.
2. Loosen the bolt and remove it.
When storing the spare tire, put it in place
with the outer side of the wheel facing up.
Then secure the tire by repeating the
above removal steps in reverse order to
prevent it from flying forward during a
collision or s udden braking.

SUPRA (U)133
ÐBlocking the wheel
2. Block the wheel diagonally opposite
the flat tire to keep the vehicle from
rolling when it is j acked up.
When blocking the wheel, place a wheel
block from the front for the front wheels
or from the rear for the rear wheels. ÐRemoving wheel ornament3. Remove the wheel ornament.
Pry off the wheel ornament, using the
beveled end of the wheel nut wrench as
shown.
CAUTION
Do not try to pull off the ornament by
hand. Take due care in handling the
ornament to avoid unexpected person-
al injury.
ÐLoosening wheel nuts
4. Loosen all the wheel nuts.
Always loosen the wheel nuts before rais-
ing the vehicle.
The nuts turn counterclockwise to loosen.
To get maximum leverage, fit the wrench
to the nut so that the handle is on the
right side, as shown above. Grab the
wrench near the end of the handle and
pull up on the handle. Be careful that the
wrench does not slip off the nut.
Do not remove the nuts yet±just unscrew
them about one- half turn.

ÐPositioning the jack
5. Position the jack at the correct jack
point as shown.
Make sure the jack is positioned on a
level and solid place. ÐRaising your vehicle6. After making sure that no one is in
the vehicle, raise it high enough so
that the spare tire can be installed.
Remember you will need more ground
clearance when putting on the spare tire
than when removing the flat tire.
To raise the vehicle, insert the jack handle
into the jack (it is a loose fit) and turn it
clockwise. As the jack touches the vehicle
and begins to lift, double- check that it is
properly positioned.
CAUTION
Never get under the vehicle when the
vehicle is supported by the jack
alone.

SUPRA (U)135
ÐChanging wheels
7. Remove the wheel nuts and change
tires.
Lift the flat tire straight off and put it
aside.
Roll the spare wheel into position and
align the holes in the wheel with the bolts.
Then lift up the wheel and get at least the
top bolt started through its hole. Wiggle
the tire and press it back over the other
bolts.Before putting on wheels, remove any cor-
rosion on the mounting surfaces with a
wire brush or such. Installation of wheels
without good metal- to- metal contact at the
mounting surface can cause wheel nuts to
loosen and eventually cause a wheel to
come off while driving. Therefore after the
first 1600 km (1000 miles), check to see
that the wheel nuts are tight. ÐReinstalling wheel nuts8. Reinstall all the wheel nuts finger
tight.
Reinstall the wheel nuts and tighten them
as much as you can by hand. Press back
on the tire back and see if you can tight-
en them more.

SUPRA (U)

ÐLowering your vehicle
9. Lower the vehicle completely and
tighten the wheel nuts.
Turn the jack handle counterclockwise to
lower the vehicle.
Use only the wheel nut wrench to tighten
the nuts. Do not use other tools or any
additional leverage other than your hands,
such as a hammer, pipe or your foot.
Make sure the wrench is securely en-
gaged over the nut.
Tighten each nut a little at a time in the
order shown. Repeat the process until all
the nuts are tight.
CAUTION
When lowering the vehicle, make sure
all portions of your body and all oth-
er persons around will not be injured
as the vehicle is lowered to the
ground.
ÐReinstalling wheel ornament
10. Reinstall the wheel ornament.
Put the wheel ornament into position and
then tap it firmly with the side or heel of
your hand to snap it into place.
CAUTION
Take due care in handling the orna-
ment to avoid unexpected personal
injury.
