NOTICE
Do not drive the vehicle with the oil
pressure below the normal range untilthe cause is fixedÐit may ruin theengine.
Vo l t m e t e r
The voltmeter tells whether the battery
is charged or discharged. Check it
while the engine is runningÐthe needle
should always indicate as shown above.
If the needle reads below or above the
normal range while the engine is running,
it indicates the charging system needs im-
mediate repair.
However, it is normal for the needle to
drop below the normal range during en-
gine starting.
Tachometer
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 over±revving.
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 causesevere engine damage.

CAUTION
If the light does not turn off even
after the parking brake is released
while the engine is running, immedi-
ately stop your vehicle at a safe
place and contact your Toyota dealer.
In this case, the brakes may not work
properly and your stopping distance
will become longer. Depress the brake
pedal firmly and bring the vehicle to
an immediate stop.
(b) Driver's Seat Belt Reminder Light
and Buzzer
This light and buzzer remind you to
buckle up the driver's seat belt.
Once the ignition key is turned to ªONº or
ªSTARTº, the reminder light flashes and
buzzer sounds 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. (c) Front Passenger 's Seat Belt Re-
minder Light
This light reminds you to buckle up the
front passenger 's seat belt.
Once the ignition key is turned to ªONº or
ªSTARTº, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt. Unless
the front passenger fastens the belt, the
light keeps flashing.
If luggage load is placed on the front
passenger seat, depending on its weight
and how it is placed on the seat, built±in
sensors in the seat cushion may detect
the pressure, causing the reminder light to
keep flashing.
(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) 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.

the brake system warning light is off), the
anti±lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the ªABSº warning light is on (and
the brake system warning light is off), the
anti±lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.

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 ªONº posi-
tion, or the light remains on.

are completely closed.
(j) SRS Warning Light
This light will come on when the igni-
tion key is turned to the ªACCº or
ªONº position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, front seat belt pretensioner assem-
blies, 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.
