With tachometer
Without tachometer The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, 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
conditioning on in stop- and- go traffic.
Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as thismay cause the engine to overheat.The thermostat is designed to con-
trol the flow of coolant to keep thetemperature of the engine withinthe specified operating range.
Do not continue driving with an overheated engine. See ºIf your ve-hicle overheatsº in Part 4.

(a) Brake System Warning Light
This 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.
Remember that stopping distance and ped-
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.
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.
(b) 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 stays on and the buzzer
sounds for about 4 to 8 seconds.
(c) 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.
(d) 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.

CARING FOR YOUR COMPACT DISC
PLAYER AND DISCS Use only compact discs labeled as
shown.
Extremely high temperatures can keep
your compact disc player from working.
On hot days, use the air conditioning
to cool the vehicle interior before you
listen to a disc.
Bumpy roads or other vibrations may
make your compact disc player skip.
If moisture gets into your compact disc
player, you may not hear any sound
even though your compact disc player
appears to be working. Remove the
disc from the player and wait until it
dries.
Handle compact discs carefully, espe-
cially when you are inserting them.
Hold them on the edge and do not
bend them. Avoid getting fingerprints
on them, particularly on the shiny side.
Dirt, scrapes, warping, pin holes, or
other disc damage could cause the
player to skip or to repeat a section of
a track. (To see a pin hole, hold the
disc up to the light.)
Remove discs from the compact disc
player when you are not listening
to them. Store them in their plastic
cases away from moisture, heat, and
direct sunlight.
To clean a compact disc: Wipe it with a
soft, lint- free cloth that has been damp-
ened with water. Wipe in a straight line
from the center to the edge of the disc
(not in circles). Dry it with another soft,
lint- free cloth. Do not use a conventional
record cleaner or anti- static device.A new disc may have rough edges on
its inner and outer perimeter. Remove
the rough edges by pressing the side
of a ball- point pen or pencil against
the inner and outer perimeter of the
disc as shown.
If you continue to play a disc with rough
edges, flakes will fall on to the signal side
of the disc and cause sound skipping or
other problems.

ÐAir flow selector settings
ÐOperating tips
To cool off your Toyota after it has
been parked in the hot sun, drive with
the windows open for a few minutes.
This vents the hot air, allowing the air
conditioning to cool the interior more
quickly.
Make sure the air intake grilles in front
of the windshield are not blocked (by
leaves or snow, for example).
On humid days, do not blow cold air
on the windshield. The windshield could
fog up because of the difference in air
temperature on the inside and outside
of the windshield.
Keep the area under the front seats
clear to allow air to circulate through-
out the vehicle.
On cold days, move the fan speed to
ºHIº for a minute to help clear the in-
take ducts of snow or moisture. This
can reduce the amount of fogging on
the windows.
