To open the glovebox door, pull the
lever. To lock the glovebox door, insert
the master key and turn it clockwise.
With the instrument panel lights on, the
glovebox light w ill come on when the door
is open.
To reduce the chance of injury in
case of an accident or a sudden
stop, always keep the glovebox
door closed while driving. CAUTION
!
When you open the back door, the lug-
gage cover tilts up for easy access to the luggage area.
For additional luggage space, unhook the retractable cords and lift the cover out of the retainers.AUTOMATIC MODE
The traction control system automati-
cally controls spinning of the rear
wheels which may occur when accel-
erating on
slippery road surfaces, thus
assisting driver control and driving
power to the rear wheels. When you turn the ignition switch on, the trac-
tion control system always turns on
automatically, and the slip indicator
light and SNOWº indicator light will come on. The indicator lights will go
off after about 3 seconds.
Glovebox Luggage cover Traction control system

105
Leave the system on during ordinary
driving so that it can operate when
needed. When traction control is ap-
plied, the slip indicator light blinks. If
your vehicle still skids even though
traction control is applied, more pow-
erful
traction control is applied and the
SNOWº indicator light comes on.
You may hear a slight clicking noise in the
engine compartment when the engine is
started. This means that the traction con-
trol system is in the self-check mode, and
does not indicate malfunction. When the
traction control system is operating, you
may feel vibration of your vehicle, causedby operation of the brakes. This indicates
the system is functioning properly.
When getting the vehicle out of mud or
new snow, etc. the traction control system
will operate to prevent the wheels from
spinning. Even though the accelerator
pedal is fully depressed, the engine speed
will be restrained to a certain level.
MANUAL SNOW OPERATION
You can select the snow mode by
pushing the SNOWº switch. The
SNOWº indicator light will come on.
To select the automatic mode, push
the OFFº switch. The SNOWº indi-cator light will go off. If your vehicle
still skids, the system automatically operates.
MANUAL TRACTION CONTROL OFF
OPERATION
You can turn off the traction control
system by pushing the OFFº switch.
The TRAC OFFº indicator/warning
light will come on. Pushing the OFFº
switch a second time turns on the trac-
tion control system and the TRAC
OFFº indicator/warning light will go off. If the SNOWº indicator light is on,
pushing the OFFº switch once se-lects the automatic mode and pushing
it a second time turns off the traction
control system.

108If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady sp
eed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no cause
for concern.
GASOLINES CONTAINING DETER-
GENT ADDITIVES
Toyota recommends use of gasolines
that contain detergent additives to
avoid build-up of engine deposits.
For further details, ask your Toyota dealer
or a local gasoline retailer..
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Methyl
Tertiary-Butyl Ether) are available in
the market. If you use a gasoline mixed
with MTBE, make certain that it does
not contain more than 15% of MTBE.
If the use of gasolines containing MTBE causes poor driveability and/or poor fuel
economy, you should discontinue the use
of fuels containing MTBE. GASOLINES CONTAINING ALCOHOL I
f you use gasohol in your Toyota, be
sure that it is unleaded, has an octane
rating no lower than 87 and does not
contain more than 10% ethanol.
Gasohol is a mixture of gasoline and etha-
nol.
Toyota does not recommend the use of
gasolines containing methanol. If you use
gasoline containing methanol, use only
gasoline meeting the requirements above
and also containing less than 5% metha-
nol with cosolvents and corrosion inhibi-
tors for methanol.
NOTICE
Do not use gasohol other than
stated above. It will cause fuel
system damage or vehicle perfor-
mance problems.
If driveability problems are en-countered (poor hot starting, va-porizing, engine knock, etc.),discontinue the use.
Take care not to spill gasohol dur-
ing refueling. Gasohol may causepaint damage.
FUEL TANK CAPACITY 70 L (18.5 gal., 15.4 Imp. gal.) If you plan to drive your Toyota in
another country... First,
comply with the vehicle registration
laws. Second, confirm the availability of the
correct fuel (unleaded and minimum oc- tane number). Operation in foreign countries

The amount of engine oil consumed
depends on
the viscosity of the oil, the
quality of the oil and the conditions
the vehicle is driven under.
More oil is consumed by high-speed driv-
ing and frequent acceleration and decel- eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, note that the oil may be- come diluted and make it difficult to
judge the true level accurately.
As an example, if a vehicle is used for re-
peated short trips, and consumes a nor- mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This is
because the oil is gradually becoming di-
luted with fuel or moisture, making it ap-
pear that the oil level has not changed.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it appear that oil is excessively consumed
after driving at high speeds. IMPORTANCE OF ENGINE OIL LEVEL CHECK
One of the most important points in proper vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will
not be impaired. Therefore, it is essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level be checked every time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to serious
engine trouble due to insufficientoil.
For detailed information on oil level check,
see Checking the engine oil levelº in Chapter 7-2. TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fail, the other w
ill still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
Also, the brake system warning light may come on.
Do not drive your vehicle with only
a single brake system. Have your
brakes fixed immediately.
CAUTION!
BRAKE BOOSTER
The brake booster uses engine vacuum to
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reservevacuum for one or two stopsÐbut no more!
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re- serve.
CAUTION!
Brake system

11 2
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder t han nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM
The anti-lock brake system is designed to prevent lock-up of the wheels during sud-
den braking or braking on slippery road surfaces. This assists the driver in con-
trolling the vehicle under these circum-stances.
The anti-lock brake system becomes op- erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.
When the anti-lock brake system function is in action, you may feel the brake pedal
pulsating and hear a noise. In this situa-
tion, to let the anti-lock brake system work for you, just hold the brake pedal
down more firmly. Do not pump the brake. The brake pedal pulsation caused by the
anti-lock brake system may indicate haz- ardous road surface conditions. Althoughthe anti-lock brake system assists in pro-
viding
vehicle control, it is still important to
drive with all due care, because the anti-
lock brake system cannot overcome the
laws of physics that act on your vehicle: Braking c apability is dependent on tire
friction with the road surface.
Even though the anti-lock brake sys-
tem is operating, a driver cannot main- tain full control on certain slippery road
surfaces, when cornering at highspeeds, or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot elimi-
nate the risk of hydroplaning and lossof tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with ve-
hicles not fitted with an anti-lock brake
system, your vehicle may require a longer
stopping distance in the following cases: Driving on rough, gravel or snow-cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differences in surface height.
ABSº warning light
This light comes on when the ignition key is turned to the ONº position. After about
3 seconds, the light will go off.
If either of the following conditions occurs, this indicates a malfunction somewhere inthe parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle. The light does not come on as de-
scribed above, or remains on.
The light comes on while driving.

How to save fuel and make
your vehicle last longer, too
1. Check the area around the vehicle be-
fore entering it.
2. Adjust seat position, seatback angle
and steering wheel angle.
3. Adjust inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces- sories. 3.
Manual transmission: Press the
clutch pedal to the floor and shift the trans-
mission into neutral. Hold the clutch pedal
to the floor until the engine is started. A
starter safety device will prevent the start-
er from operating if the clutch pedal is not fully depressed.
Automatic transmission: Put the selec-
tor lever in Pº. If you need to restart the
engine while the vehicle is moving, put the
selector lever in Nº. A starter safety de-vice will prevent the starter from operating
if the selector lever is in any drive position. 4. Automatic transmission only: De-
press the brake pedal and hold it to the
floor until driving off.

11 9

Always slow down in gusty cross- winds. This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid drivingonto high, sharp-edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.
When parking on a hill, turn the front
wheels until they touch the curb so that
the vehicle will not roll. Apply the park-
ing brake, and place the transmission in Pº (automatic) or in first or reverse
(manual). If necessary, block thewheels.
Washing your vehicle or driving
through deep water may get the
brakes wet. To see whether they are
wet, check that there is no traffic near
you, and then press the pedal lightly. If
you do not feel a normal braking force,
the brakes are probably wet. To dry
them, drive the vehicle cautiously
while lightly pressing the brake pedal
with the parking brake pulled. If they
still do not work safely, pull to the side
of the road and call a T oyota dealer for
assistance.
CAUTION
Before driving off, make sure the
parking brake is fully released and the parking brake reminder light is off.
Do not leave your vehicle unat- tended while the engine is run-ning.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat
and not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking
on a slippery surface. Sudden ac-
celeration or engine braking could cause the vehicle to spin or skid.!
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high-speed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss of
control and possible injury. Be sure to consult a tire dealer to de-
termine whether the tires on your
vehicle are high-speed capability tires or not before driving at suchspeeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking
brake will not hold the vehicle se-
curely.
Tips for driving in various conditions

121
Toyota does not recommend towing a
trailer with your Supra. It is not designed for trailer towing.Getting
more kilometers/mileage from a li-
ter/gallon of fuel is easyÐjust take it easy.
It will help make your vehicle last longer,
too. Here are some specific tips on how to
save money on both fuel and repairs: Keep your tires inflated at the cor- rect pressure. Underinflation causes
tire wear and wastes fuel. See Chapter
7-2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing greater fuel consumption.
Avoid lengthy warm-up idling.
Once the engine is running smoothly,
begin drivingÐbut gently. Remember,
however, that on cold winter days this
may take a little longer.
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid long engine idling. If you have
a long wait and you are not in traffic, it
is better to turn off the engine and start
again later.
Avoid engine lug or overrevving.
Use a gear position suitable for the
road on which you are travelling.
Avoid continuous speeding up and
slowing down. Stop-and-go driving
wastes fuel.
Avoid unnecessary stopping andbraking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or take
advantage of through streets to avoid
traffic lights. Keep a proper distance
from other vehicles to avoid sudden braking. This will also reduce wear on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econ-
omy.
Maintain a moderate speed on highways. The faster you drive, the
greater the fuel consumption. By re-
ducing your speed, you will cut down
on fuel consumption.
Keep the front wheels in proper alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on the
engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps prevent corrosion.

(a) Simple checks
123
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 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 dis-
charged. You may try jump starting. See
(c) Jump startingº 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 qualified repair shop.
NOTICE
Do not pull- or push-start the vehicle. It may damage the vehicle or
cause a collision when the engine starts. Also the three-way catalyticconverter may overheat and become
a fire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. 2JZ-GE engineÐCheck that all the
push-on connectors are tight. (For exam-
ple, connectors at the distributor and spark plugs)
2. If the connectors are O.K., the engine
may be flooded because of repeated cranking. See (b) Starting a flooded en-
gineº for further instructions.

124If 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 15 seconds at a time. This may o verheat
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 cables designed for
jump starting 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 battery is correct.
JUMP STARTING PROCEDURE
1. If the booster battery is installed in
another vehicle, make sure the vehicles
are not touching. Turn off all unnecessary
lights and accessories.
2. If required, remove all the vent plugs from the booster and discharged batter- ies. Lay a cloth over the open vents on the
batteries. (This helps reduce the explo-
sion 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 de- pressed.
