CAUTION
If any of the following conditions oc-
curs, immediately stop your vehicle at
a safe place and contact your Toyota
dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
The warning buzzer comes on to-
gether with the warning light.
In either case, this can indicate that
the brakes may not work properly
and your stopping distance will be-
come longer. Depress the brake
pedal firmly and bring the vehicle
to an immediate stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The light may stay on for about 60
seconds after the ignition key is turned
to the “ON” position. It is normal if it
turns off after a while.
Depressing the brake pedal repeatedly
may turn on the warning light and
buzzer. It is normal if the light turns off
and the buzzer stops sounding after a
few seconds.
You may hear a small sound in the
engine compartment after the engine is
started or the brake pedal is depressed
repeatedly. This is a pump pulsating
sound of the brake system, and it is
not a malfunction.
(b) Seat Belt Reminder Light and Buzz- er
This light and buzzer remind you to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON” or
“START”, 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 Engine 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 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

warning light on—even for one block.
It may ruin the engine.
(e) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and

after taking several driving trips.
If the lamp will not go off even after the
several trips, contact your Toyota dealer
as soon as possible.
If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, auto-
matic transmission electrical system or
warning light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
Four −wheel drive models and Pre Runner
with 5VZ −FE engine only—
If the engine speed does not increase with
the accelerator pedal depressed down to
about the middle position, there may be
a problem somewhere in your electronic
throttle control system. At this time, if you depress the accelera-
tor pedal more firmly and slowly, you can
drive your vehicle at low speeds. Have
your vehicle checked by your Toyota deal-
er as soon as possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to “ACC” or
“LOCK” position.CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions Inspection and Maintenance

ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(g) “ABS” Warning Light (without ve-hicle stability control system)
The light comes on when the ignition key
is turned to the “ON” position. If the anti −
lock brake system works properly, the
light turns off after a few seconds. There-
after, if the system malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
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 “ABS” 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. 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 “ON” posi-
tion, or the light remains on.

is turned to the “ON” position. If the anti −
lock brake system and the brake assist
system work properly, the light turns off
after a few seconds. Thereafter, if either
of the systems malfunctions, the light
comes on again. When the “ABS” warning light is on (and
the brake system warning light is off), the
following systems do not operate, but the
brake system still operates conventionally.
Anti
−lock brake system
Brake assist system
Traction control system
“AUTO LSD” system
Vehicle stability control system
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate,
so that the wheels will lock up during a
sudden braking or braking on slippery
road surfaces.
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components 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 “ON” posi-
tion, or remains on.
