2º 115 km/h (72 mph)Lº 63 km/h (39 mph)
2JZ-GTE engine 2º 130 km/h (81mph)Lº 70 km/h (44mph)
Do not continue hill climbing orhard towing for a long time in the2º or Lº position. This may
cause severe automatic transmis-
sion damage from overheating. To
prevent such damage, Dº posi-
tion should be used in hill climb-ing or hard towing.
(d) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the Rº
position.
NOTICE
Never shift into reverse while the vehicle is moving.
(e) Parking
1. Bring the vehicle to a complete stop.
2. Pull the parking brake lever up fully to securely apply the parking brake.
3. With the brake pedal pressed down,
shift the selector lever to the Pº position.
While the vehicle is moving, never
attempt to move the selector lever
into Pº position under any circum-
stances. Serious mechanical dam-
age and loss of vehicle control may result. CAUTION
!
(f) Good driving practice
If the transmission is repeatedly upshifted
and downshifted between third gear and
overdrive when climbing a gentle slope,
the overdrive switch should be turned off. Be sure to turn the switch on immediatelyafterward.
Always keep your foot on the brake
pedal w hile stopped with the engine
running. This prevents the vehicle
from creeping. CAUTION
!
NOTICE
Do not hold the vehicle on an upgrade with the accelerator pedal.
It can cause the transmission to overheat. Always use the brakepedal or parking brake.
(g) Driving in manual mode

The automatic air conditioning is an air
conditioning that automatically maintains the set temperature.
This air conditioning features automatic
air intake controls, fan speed and air flow controls which automatically select the
most suitable air intake control, fan speed
and air flow to control the temperature.
You may use manual controls if you desire your own way of setting.
(A) CLIMATE CONTROL Setting operation
1. Turn the temperature control knob at the desired temperature level.
The temperature control knob is used to
set the desired passenger compartment
temperature. The tem
perature of air deliv-
ered to the passenger compartment will
be controlled automatically according to
the setting. The figures on the panel indi-
cate degrees in centigrade or Fahrenheit. 2. Press in the AUTOº button.
As the AUTOº button is pressed in, the fan turns on and operates with the most
suitable air intake control, air flow (except
pressing the FLOOR/WINDSHIELD or
WINDSHIELD button) and fan speed se-lected
automatically according to the tem-
perature. In cold weather, however, the
fan will not operate until the engine cool-
ant warms up sufficiently.
3. If any of the AUTOº button functions is not necessary for your own way of set-
ting, manual control can be made on each
of the functions, leaving the rest of the
functions in operation. Operate the con-
trols as described in Manual control on air
intake, air flow and fan speedº after the
AUTOº button is pressed in.
4. Press in the air conditioning on-off but-
ton.
The air conditioning on-off button is used
to turn on and off the air conditioning.
With the button pressed in the on mode, the air conditioning turns on.
If the system is used for ventilation or
heating in dry weather, press the air con-
ditioning on-off button once again. This
turns off the air conditioning. For year-
round automatic temperature control in-
cluding cooling and dehumidifying opera-
tion, use the air conditioning. 5. Press in the OFFº button turn off thefan speed and temperature control.
Manual control on air intake, air flow
and fan speed
If manual air intake control is de- siredÐ
The air intake control button is used to se-
lect intake air, either outside air or recircu-
lated air. With the button in the OUTSIDE
AIR mode, the OUTSIDE AIR mode indi-
cator light w
ill come on and the system will
take fresh outside air into the unit.
If quick circulation of conditioned air is de- sired, press in the air intake control button
to select the RECIRCULATED AIR mode
for recirculated air. The RECIRCULATED
AIR mode indicator light will come on.
For normal use, it is best to keep the air in-
take control button for outside air. If recir-
culated air is used during heating, the win-
dows will fog up more easily.
If manual air flow selection is de- siredÐ
The air flow outlets from which air is deliv-
ered can be selected manually by press-
ing in the appropriate air flow control but-
ton. The function of each button is as follows:
FACE buttonÐThis button directs the air flow to face level.

CAUTION!
Avoid inhaling the engine exhaust.
It contains carbon monoxide,
which is a colorless and odorless
gas. It can cause unconsciousness
or even death.
Make sure the exhaust system has
no holes or loose connections. The
system should be checked from
time to time. If you hit something,
or notice a change in the sound of
the exhaust, have the system
checked immediately.
Do not run the engine in a garage or
enclosed area except for the time
needed to drive the vehicle in or
out. The exhaust gases cannot es-
cape, making this a particularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined area and adjust the heating or cooling
system to force outside air into the vehicle.
Keep the back door closed while
driving. An open or unsealed back
door may cause exhaust gases to
be drawn into the vehicle. If you
must drive with the back door
open to accommodate a large ob-
ject, close the windows, open all
the instrument panel vents and have the heating or cooling sys- tem deliver fresh air into the ve-
hicle by turning the fan to high
speed with the air intake control
button in the OUTSIDE AIR mode.
To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or
other obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the back door closed.
Have the cause immediately lo-cated and corrected. FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lu-
bricating and cooling the inside of the en-
gine,
and plays a major role in maintaining
the engine in proper working order. ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are
as follows. Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil is left on the cylinder wall when a piston
moves downwards in the cylinder.
High negative pressure generated
when the vehicle is decelerating sucks
some of this oil into the combustion
chamber. This oil as well as some part
of the oil film left on the cylinder wall is
burned by the high temperature com-
bustion gases during the combustionprocess.
Oil is also used to lubricate the stems
of the intake valves. Some of this oil is
sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem- perature exhaust gases also burn the
oil used to lubricate the exhaust valve stems.

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

120Make sure you have ethylene-glycol
antifreeze in the radiator.
Do not use alcohol type antifreeze.
NOTICE
Check the condition of the battery and cables. Cold temperatures reduce the capacity of
any battery, so it must be in top shape to provide enough power for winter starting.Chapter 7-3 tells you how to visually in-
spect the battery. Your Toyota dealer and
most service stations will be pleased tocheck the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Chapter 7-2 for recommended vis-
cosity.
Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealerÐ
he will be pleased to help. Keep the door locks from freezing. Squirt lock de-icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before in-serting it. Use a washer fluid containing an anti-
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer's directions for how
much to mix with water.NOTICE
Do not use engine antifreeze or any other substitute as washer fluid be-
cause it may damage your vehicle's
paint.
Do not use your parking brake when there is a possibility it could freeze. When parking, put the transmission into
Pº (automatic) or into first or reverse
(manual) and block the rear wheels. Do
not use the parking brake, or snow or wa-
ter accumulated in and around the parkingbrake mechanism may freeze, making it
hard to release. Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad winter driving, stop and check under the
fenders occasionally. Depending on where you are driving,
we recommend you carry some emer- gency equipment.
Some of
the things you might put in the ve-
hicle are tire chains, window scraper, bag of sand or salt, flares, small shovel, jump- er cables, etc.
Winter driving tips

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.

your vehicle last longer, too

126Do not connect the cable to or near any
part that moves when the engine is cranked.
NOTICE
When making the connections, do not lean over the battery or
accidentally let the jumper cables or clamps touch anything exceptthe correct battery terminals or the ground.
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm for several minutes with the accelerator ped-
al 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 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 vehicle
and turn on your emergency flashers. Put
the transmission in Pº (automatic) or neu-
tral ( manual) and apply the parking brake.
Turn off the air conditioning if it is beingused.
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 vehicle. However, note that water draining from the air condi-
tioning is normal if it has been used.
