OPERATION OF INSTRUMENTS AND CONTROLSÐ
Chapter 1-5 Gauges, Meters and Service reminderindicators
Fuel gauge
Engine coolant temperature gauge
Tachometer
Odometer and two trip meters
Service reminder indicators and warning buzzers
The gauge works when the ignition
switch is on
and indicates the approxi-
mate quantity of fuel remaining in the tank.
It is a good idea to keep the tank over 1/4 full.
This fuel gauge has a non-return type
needle wh ich remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches Eº or the low fuel level warning light comes on, fill the fuel tank as soon as possible.
If the fuel tank is completely empty, the malfunction indicator lamp comes on. Fill
the fuel tank immediately. The indicator lamp goes off after driving several times. If the indicator lamp does
not go off, contact your Toyota dealer assoon as possible.

The gauge indicates the engine cool-
ant temperature when the ignition
switch is on. The engine operating
temperature will vary with changes inweather and engine load.
If the needle points to the red zone or high-
er, stop your vehicle and allow the engine
to cool.
Your vehicle may overheat during severe operating conditions, such as: Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air con-
ditioning on in stop-and-go traffic.
NOTICE
Do not remove the thermostat in the engine cooling system as this
may cause the engine to overheat. The thermostat is designed tocontrol the flow of coolant to keep
the temperature of the engine within the specified operatingrange.
Do not continue driving with an
overheated engine. See If yourvehicle overheatsº in Part 4.
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overr evving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get into the red zone. This may cause
severe engine damage.

This meter displays the odometer and
two trip meters. To change the odome-
ter display to the trip meter display,
push the ODO TRIPº button. To reset
the trip meter A to zero, display the me-
ter A reading, then push the RESETº
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 measure the distance on each trip. All trip meterdata is cancelled if the electrical power source is disconnected.The meter display changes each time youpush the ODO TRIPº button, changing in order from the odometer to trip meter A to
trip meter B, then back to the odometer.

Service reminder indicators
and warning buzzers

52
(a) Master Warning Light
This light warns that another service re-
minder indicator (except seat belt remind-
er light, low fuel level warning light, rear
light failure warning light, SRS airbag
warning light and TRAC OFFº indicator/warning light) is on.
If it comes on while you are driving, check
the other service reminder indicator that is
on with reference to the following descrip-
tion of the indicator.
(b) Brake System Warning LightThis light has the following functions: Parking brake reminder
If this light is on, make sure the parking
brake is fully released. The light should go
off.
Low brake fluid level warning
If this light comes on and stays on while
you are driving, slow down and pull off the
road. Then stop the vehicle carefully. There maybe a problem somewhere in
the brake system. Check the fluid level of
the see-through reservoir.
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.

53
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.)
It is dangerous to continue driving
normally when the brake fluid level
is low. CAUTION
!
If the brake fluid level is correct...
Have the warning system checked by
your Toyota dealer.
(c) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ONº or
STARTº, the reminder light and buzzer
come on if the driver's seat belt is not fas-tened. Unless the driver fastens the belt,
the light stays on and the buzzer stops af-
ter 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 dischar-
ged. Turn off the air conditioning, blower,
radio, etc., and drive directly to the near-
est 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 Fuel gaugeº in Chapter 1-5 for in-structions.)
b. There is a problem somewhere in your
engine or automatic transmission electri- cal system.
If it comes on while you are driving in case
b, have your vehicle checked/repaired 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.
(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 driv-
ing, pull off the road to a safe place and
stop the
engine immediately. Call a Toyota
dealer or qualified repair shop for assis- tance.
The light may occasionally flicker when
the engine is idling or it may come on brief-
ly after a hard stop. There is no cause for concern if it then goes out when the en-
gine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to indi-cate low oil level, and the oil level must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the warning light onÐeven 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 Checking the engine oil
levelº in Chapter 7-2.)
NOTICE
Continued engine operation with low engine oil will damage the
engine.

54(i) ABSº 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 driving,
have your vehicle checked by your T
oyota
dealer as soon as possible.
The light will come on when the ignition key is turned to the ONº position. After
about 3 seconds, the light will go off. When the ABSº warning light is on (and
the brake system warning light is off), thebrake system operates conventionally but
without anti-lock function.
(j) Open Door Warning Light
This light remains on until both side doors
and back door are completely closed.
(k) Rear Light Failure Warning LightIf this light comes on when the headlight
switch is turned on (at the first or second
clickstop), it indicates that one or more ofthe tail lights are burned out.
If it comes on when the brake pedal is de-
pressed, 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 ACCº or ONº
position. After about 6 seconds, the
light will go off. This means the airbag
system is operating properly.
The warning light system monitors the
front airbag sensors, center airbag sensor
assembly, inflators, warning light, inter-
connecting 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. The light does not come on when the
ignition key is turned to the ACCº or
ONº position or remains on.
The light comes on while driving.
(m) TRAC OFFº Indicator/Warning light
This light comes on when the ignition key
is turned to ONº, 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 sec- onds after the ignition switch is turned on.
The light comes on while driving evenif the TRAC 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 ACCº or LOCKº position.
CHECKING SERVICE REMINDER INDI-
CATORS (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 ACCº.
The SRS airbag warning light should
come on. It goes off after about 6 sec-onds.
5. Turn the ignition key to ONº, but do not
start the engine.

55
All the service reminder indicators except the open door warning light and SRS air-
bag warning light should come on. The
ABSº
warning light and TRAC OFFº indi-
cator/warning light go off after about 3seconds.
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 pos-sible.

StartºÐStarter m otor on. The key will
return to the ONº position when re- leased.
For starting tips, see Part 3. ONºÐEngine on and all accessories on. This is the normal driving position.
ACCºÐAccessories such as the ra-
dio operate, but the engine is off.
If you leave the key in the ACCº or
LOCKº position and open the driver's
door, a buzzer will remind you to remove
the key.
LOCKºÐEngine is off and the steer-
ing wheel is locked. The key can be re-
moved only at this position. You must push in the key to turn the key
from ACCº to the LOCKº position. On
vehicles with an automatic transmission,
the selector lever must be put in the Pº
position before pushing the key. When starting the engine, the key may
seem stuck at the LOCKº position. To
free it, first be sure the key is pushed all
the way in, and then rock the steering
wheel slightly
while turning the key gently.For manual transmission: Never remove the key when the ve-
hicle is moving, as this will lock the
steering wheel and result in loss ofsteering control. CAUTION
!
NOTICE
Do not leave the key in the ONº position if the engine is not running.
The battery will discharge and the ignition could be damaged.

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 Cruise controlº i n
this chapter.
