(g) Low Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on±even for one block.It may ruin the engine.
(h) Low Engine Oil Level Warning Light
The light warns that the engine oil level is
too low. Add oil as soon as possible. (For
instructions, see ºChecking the engine oil
levelº in Chapter 7- 2.) While driving on steep inclines or rough
roads which causes the vehicle to sub-
stantially sway or on curves, this light
may come on due to the movement of
engine oil in the engine.
NOTICE
Continued engine operation with low
engine oil will damage the engine.
(i) ºABSº Warning Light
This light warns that there is a problem
somewhere in your anti- lock brake sys-
tem.
If the light comes on while you are driv-
ing, have your vehicle checked by your
Toyota dealer as soon as possible.
The light will come on when the ignition
key is turned to the ºONº position. After
a few seconds, the light will go off.
When the ºABSº warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti- lock brake system is not assisting
brake performance so that the wheels can
lock- up during sudden braking or braking
on slippery road surfaces. (j) Open Door Warning Light
This light remains on until both side doors
and back door are completely closed.
(k) Rear Light Failure Warning Light
If this light comes on when the headlight
switch is turned on (at the first or second
clickstop), it indicates that one or more of
the tail lights are burned out.
If it comes on when the brake pedal is
depressed, one or more stop lights are
burned out or the stop light circuit is in
need of repair.
Have defective bulbs replaced as soon as
possible.
(l) SRS Airbag Warning Light
This light will come on when the igni-
tion key is turned to the ºACCº or
ºONº position. After about 6 seconds,
the light will go off. This means the
airbag system is operating properly.
The warning light system monitors the air-
bag sensor assembly, inflators, warning
light, interconnecting wiring and power
sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.

SUPRA (U)65

The light does not come on when the
ignition key is turned to the ºACCº or
ºONº position or remains on.
The light comes on while driving.
(m) ºTRAC OFFº Indicator/Warning
Light
This light comes on when the ignition key
is turned to ºONº, and will go off after 3
seconds. This means that the system is
operating properly.
If one of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light remains on more than 3 se-
conds after the ignition switch is turnedon.
The light comes on while driving even
if the ºTRAC OFFº switch is not
pushed.
The light flashes.
(n) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver 's door with
the ignition key in the ºACCº or ºLOCKº
position. CHECKING SERVICE REMINDER INDICA-
TORS (except the low fuel level warning
light)
1. Apply the parking brake.
2. Open one of the side doors or the back door.
The open door warning light should
come on.
3. Close the side door. The open door warning light should go
off.
4. Turn the ignition key to ºACCº. The SRS airbag warning light should
come on. It goes off after about 6 se-
conds.
5. Turn the ignition key to ºONº, but do not start the engine.
All the service reminder indicators except
the open door warning light and SRS air-
bag warning light should come on. The
ºABSº warning light goes off after about 3
seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, either the bulb is burned out or the
circuit is in need of repair. Have it
checked by your Toyota dealer as soon as
possible.

Automatic transmission
When the cruise control is being used, even if you downshift the transmi
ssion by turning off the overdrive switch, engine braking will
not be applied because the cruise control is not cancelled. For ways to decrease the vehicle speed, see ºCruise controlº in this
chapter.

SUPRA (U)69
Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of ºPº position when the
brake pedal is depressed (with the ignition
switch in ºONº position and the lock re-
lease button depressed).
(a) Normal driving
1. Start the engine as instructed in ºHow to start the engineº in Part 3. The
transmission must be in ºPº or ºNº.
2. With your foot holding down the brake pedal, shift the selector lever to ºDº.
In ºDº position, the automatic transmission
system will select the most suitable gear
for running conditions such as normal
cruising, hill climbing, hard towing, etc.
Always turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low, the
transmission will not shift into the over-
drive gear even with the overdrive switch on.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake pedal. Depress the accelerator pedal
slowly for smooth starting.
(b) Using engine braking
To use engine braking, you can downshift
the transmission as follows: Turn off the overdrive switch. The ºO/D
OFFº indicator light will come on and
the transmission will downshift to the
third gear.
Shift into the º2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the following
speed, and more powerful engine brak-
ing will be obtained.
2JZ- GE engine 105 km/h (66 mph)
2JZ- GTE engine 130 km/h (81 mph)
Shift into the ºLº position. The trans-
mission will downshift to the first gear
when the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be ap-
plied.
2JZ- GE engine 58 km/h (36 mph)
2JZ- GTE engine 60 km/h (37 mph) When the cruise control is being used,
even if you downshift the transmission by
turning off the overdrive switch, engine
braking will not be applied because the
cruise control is not cancelled. For ways
to decrease the vehicle speed, see
ºCruise controlº in this chapter.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(c) Using the º2º and ºLº positions
The º2º and ºLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in º2º or ºLº, you
can start the vehicle in motion as with the
lever in ºDº.
With the selector lever in º2º, the vehicle
will start in the first gear and automatical-
ly shift to the second gear.
With the selector lever in ºLº, the trans-
mission is engaged in the first gear.

SUPRA (U)

NOTICE
Be careful not to overrev the en- gine. Watch the tachometer to keepengine rpm from going into the red zone. The approximate maximum al-
lowable speed for each position isgiven below for your reference:
2JZ- GE engine
º2º 105 km/h (66 mph)ºLº 58 km/h (36 mph)
2JZ- GTE engine º2º 130 km/h (81 mph)
ºLº 70 km/h (44 mph)
Do not continue hill climbing orhard towing for a long time in the º2º or ºLº position. This may cause
severe automatic transmission dam-age from overheating. To preventsuch damage, ºDº position should
be used in hill climbing or hardtowing.
(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
ºRº position.
NOTICE
Never shift into reverse while the ve-
hicle 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 ºPº posi-
tion.
CAUTION
While the vehicle is moving, never
attempt to move the selector lever
into ºPº position under any circum-
stances. Serious mechanical damage
and loss of vehicle control may re-
sult.
(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 immediately
afterward.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Do not hold the vehicle on an up-
grade with the accelerator pedal. Itcan cause the transmission to over- heat. Always use the brake pedal or
parking brake.

SUPRA (U)71
(g) Rocking your vehicle if stuck
CAUTION
If your vehicle becomes stuck in
snow, mud, sand, etc., then you may
attempt to rock the vehicle free by
moving it forward and backward. Do
not attempt this procedure if people
or objects are anywhere near the ve-
hicle. During the rocking operation
the vehicle may suddenly move for-
ward or backward as it becomes un-
stuck, causing injury or damage to
nearby people or objects.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-age to the transmission and otherparts.
Do not depress the accelerator ped-
al while shifting the selector lever or before the transmission is com-
pletely shifted to forward or reversegear.
Do not race the engine and avoidspinning the wheels.
If your vehicle remains stuck after
rocking the vehicle several times,consider other ways such as tow-ing.
(h) Driving in manual mode
In the manual mode, the transmission sys-
tem stops automatic gear shifting. Use
this mode when starting your vehicle on
a snowy or slippery road, when driving up
steep inclines, and down with engine brak-
ing.
To set the manual mode, push the
ºMANUº button. In the manual mode, the
ºMANUº mode indicator light comes on
and the transmission shifts up or down as
follows.
ºDº positionÐThe transmission is locked
in third gear.
When your vehicle speed drops down, the
transmission will shift to second gear for
smooth accelerating.
º2º positionÐThe transmission is locked in
second gear.
ºLº positionÐThe transmission is locked in
first gear.
NOTICE
Be careful not to overrev the engine
when using º2º or ºLº position.
If the automatic transmission fluid temper-
ature becomes too high, the ºMANUº
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
ºMANUº button once again. The ºMANUº
mode indicator light will go off and the
transmission system will work in the nor-
mal driving mode.
The manual mode automatically cancels
out when the ignition switch is off.
(i) If you cannot shift the selector le- ver out of ºPº position
If you cannot shift the selector lever from
the ºPº position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see ºIf
you cannot shift automatic transmission
selector leverº in Part 4.

SUPRA (U)
72
Manual transmission
The shift pattern is shown above. You
must lift up the ring around the gear
shift lever to shift into ºRº (reverse).
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 grade±use 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 approxi-
mately the following 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)
5 to 6 or 6 to 5 80 (50)
Upshifting too soon or downshifting too
late will cause lugging, and possibly ping-
ing. Regularly revving the engine to maxi-
mum speed in each gear will cause ex-
cessive engine wear and high fuel
consumption. Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speeds in each
gear:
gear km/h (mph)
1 60 (38)
2 97 (61)
3 136 (85)
4 175 (109)
NOTICE
Do not downshift if you are goingfaster than the maximum allowablespeed for the next lower gear.
Good driving practice
If it is difficult to shift into reverse, put
the transmission in neutral, release the
clutch pedal momentarily, and then try
again.

SUPRA (U)73
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
NOTICE
Make sure the vehicle is completelystopped before shifting into reverse.
Parking brake
To set: Pull up the lever.
To release: Pull up slightly, press the
thumb button, and lower.
Before leaving your vehicle, firmly apply
the parking brake. For better holding pow-
er, first depress the brake pedal and hold
it while setting the parking brake.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
Cruise control
The cruise control allows you to cruise
the vehicle at a desired speed over 40
km/h (25 mph) even with your foot off
the accelerator pedal.
Your cruising speed can be maintained up
or down grades within the limits of engine
performance, although a slight speed
change may occur when driving up or
down the grades. On steeper h ills, a
greater speed change will occur so it is
better to drive without the cruise control.

SUPRA (U)
74
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snow- covered) or
winding roads.
Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then downshift the
transmission to use engine braking
to slow down.
TURNING ON THE SYSTEM
To operate the cruise control, push the
ºCRUISE ON- OFFº switch. This turns the
system on. The indicator light in the
instrument panel shows that you can now
set the vehicle at a desired cruising
speed. Another push will turn the system
completely off.
CAUTION
To avoid accidental cruise control en-
gagement, keep the ºCRUISE ON-
OFFº switch off when not using the
cruise control.
SETTING AT A DESIRED SPEED
On vehicles with automatic transmission,
the transmission must be in ºDº before
you set the cruise control speed.
Bring your vehicle to the desired speed,
push the lever down in the ºSET/COASTº
direction and release it. This sets the ve-
hicle at that speed. If the speed is not
satisfactory, tap the lever up for a faster
speed, or tap it down for a slower speed.
Each tap changes the set speed by 1.6
km/h (1.0 mph). You can now take your
foot off the accelerator pedal.
If you need acceleration±for example,
when passing±depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CAUTION
For manual transmission:
While driving with the cruise control
on, do not shift to neutral without
depressing the clutch pedal, as this
may cause engine racing or overrev-
ving.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the control lever in the ºCANCELº
direction and releasing it.
b. Depressing the brake pedal.
c. Depressing the clutch pedal (manual
transmission).
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto- matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.
If the preset speed automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
