NOTICE
Be careful not to overrev the engine when using 2º or Lº position.
If the automatic transmission fluid tem-
perature becomes too high, the MANUº mode indicator light flashes for several
seconds and goes off. The driving mode then automatically changes from manual mode to the normal driving mode.
To cancel the manual mode, push the
MANUº button once again. The MANUº
mode indicator light will go off and thetransmission system will work in the nor- mal driving mode.
The manual mode automatically cancels
out when the ignition switch is off.
(h) If you cannot shift the selector lever out of Pº position
If you cannot shift the selector lever from the Pº position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see If you cannot shift automatic transmission selector leverº in Part 4.
The shift pattern is conventional as
shown above.
Press the clutch pedal down fully while
shifting, and then release it slowly. Do not
rest your foot on the pedal while driving, because it will cause clutch trouble. And do not use the clutch to hold the vehicle
when stopped on an uphill gradeÐuse the
parking brake. Recommended shifting speeds
The transmission is fully synchronized
and upshifting or downshifting is easy.
For the best compromise between fuel
economy and vehicle performance, you
should upshift or downshift at the follow-
ing speeds:
gear km/h (mph)
1 to 2 or 2 to 1 24 (15)
2 to 3 or 3 to 2 40 (25)
3 to 4 or 4 to 3 64 (40)
4 to 5 or 5 to 4 72 (45)
Upshifting too soon or downshifting too late
will cause lugging, and possibly pinging.
Regularly revving the engine to maximum
speed in each gear will cause excessive
engine wear and high fuel consumption. Maximum allowable speeds
To get on a highway or to pass slower traf- fic, maximum acceleration may be neces-
sary. Make sure you observe the following
maximum allowable speeds in each gear:
gear km/h (mph) 1 54 (34)
2 94 (59)
3 139 (87)

Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break-in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of your vehicle:
Do not drive over 88 km/h (55 mph).
Do not run the engine over 4000 rpm. Maintain engine speed between 2000 and 4000 rpm.
Avoid full-throttle starts.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive slowly with the manual
transmission in a high gear.
Do not drive for a long time at any
single speed, either fast or slow. FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups, your
Toyota has a new smaller fuel tank open- ing.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the
three-way catalytic converter tolose its effectiveness and the emission control system tofunction improperly. Also, this can increase maintenance costs.
OCTANE NUMBER
Select premium unleaded gasoline
with a Research Octane Number of 96
(Octane Rating 91) or higher for opti-
mum engine performance. However, if
such premium type cannot be ob-
tained, you may temporarily use un-
leaded gasoline with an octane num-ber as low as 91 (Octane Rating 87).
Use of unleaded fuel with an octane num- ber or rating lower than stated above will
cause persistent heavy knocking. If se-
vere, this will lead to engine damage.

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.

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.
