Odometer and two trip meters
This meter displays the odometer and
two trip meters. To change the odome-
ter display to the trip meter display,
push the ºODO TRIPº button. To reset
the trip meter A to zero, display the
meter A reading, then push the
ºRESETº button. The same applies for
the trip meter B.
The odometer records the total distance
the vehicle has been driven. The trip me-
ters can record two different distances in-
dependently.
You can use one trip meter to calculate
the fuel economy and the other to mea-
sure the distance on each trip. All trip
meter data is cancelled if the electrical
power source is disconnected.
The meter display changes each time you
push the ºODO TRIPº button, changing in
order from the odometer to trip meter A
to trip meter B, then back to the odome-
ter.

al effort may be increased. There may be
a problem somewhere in the brake sys-
tem. Check the fluid level of the see-
through reservoir.

SUPRA (U)63
To make sure the parking brake has not
caused the warning light to come on,
check to see that the parking brake is
fully released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping.
If you judge that the brakes still work
adequately, drive cautiously to your
nearest dealer or shop for repairs.
If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
If the brake fluid level is correct...
Have the warning system checked by your
Toyota dealer. (c) Seat Belt Reminder Light and Buzz-er
Once the ignition key is turned to ºONº or
ºSTARTº, the reminder light flashes and
buzzer comes on if the driver's seat belt
is not fastened. Unless the driver fastens
the belt, the light keeps flashing and the
buzzer stops after about 4 to 8 seconds.
(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
ºFuel gaugeº in Chapter 1- 5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ºFuel tank capº in Chapter
1- 2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electrical
system.
If it comes on while you are driving in
case c, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.

(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

(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

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.

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.
