NOTICE
Be careful not to overrev the en-gine. Watch the tachometer to
keep engine rpm from going into the red zone. The approximatemaximum allowable speed for
each position is given below foryour reference:
2JZ-GE engine
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
In the manual mode, the transmission
system stops automatic gear shifting. Use
this m ode when starting your vehicle on a
snowy or slippery road, when driving upsteep inclines, and down with enginebraking.
To set the manual mode, push the
MANUº button. In the manual mode, the
MANUº mode indicator light comes on
and the transmission shifts up or down as follows.
Dº positionÐThe transmission is locked
in third gear.
When your vehicle speed drops down, the
transmission will shift to second gear for
smooth accelerating.
2º positionÐThe transmission is locked
in second gear.
Lº positionÐThe transmission is locked
in first gear.

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.

your vehicle last longer, too
Trailer towing

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.
