(a) Brake System Warning Light
This light comes on in the following cases
when the ignition key is in the ªONº posi-
tion.

When the parking brake is applied...
This light comes on for a few seconds
when the ignition key is turned to the
ªONº position even after the parking brake
is released.

When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Toyota dealer in the following cases:

The light does not come on even if the
parking brake is applied when the igni-
tion key is in the ªONº position.

The light does not come on even if the
ignition key is turned on with the park-
ing brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, 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.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.

The brake system warning light re-
mains on together with the ªABSº
warning light.
In this case, not only the anti±lock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver's Seat Belt Reminder Light
and Buzzer
The light and buzzer act as a reminder to
buckle up the driver's seat belt.
Once the ignition key is turned to ªONº or
ªSTARTº, the reminder light flashes and
buzzer come on if the driver's seat belt
is not fastened. Unless the driver fastens
the belt, the light continues flashing and
the buzzer sounds for about 4 to 8 se-
conds.
(c) Front Passenger 's Seat Belt Re-
minder Light
The light acts as a reminder to have the
front passenger buckle up the 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.
If luggage or other load is placed on the
front passenger seat, depending on its

(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 when the ignition
key is turned to the ªONº position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on or the lamp
comes on while driving, first check the
followings.

Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.

Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp does not go off even after
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, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer 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 ªACCº or
ªLOCKº position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions inspection and maintenance
(I/M) programs
We recommend you to contact your
Toyota dealer to check your vehicle's
emission control system and OBD
(On±Board Diagnostics) system before
taking your vehicle for a state emission
inspection.
For details, see ªEmissions Inspection and
Maintenance (I/M) programsº on page 416
in Section 6.

(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) ªABSº Warning Light
The light comes on when the ignition key
is turned to the ªONº 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 ªABSº warning light is on (and
the brake system warning light is off), the
anti±lock brake system, the brake assist
system, the traction control system (two±
wheel drive vehicles), the active traction
control system (four±wheel drive vehicles)
and the vehicle stability control system do
not operate, but the brake system still
operates conventionally.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.
If either of the following conditions
occurs, this indicates a malfunction
somewhere in the components moni-
tored by the warning light system. Con-
tact 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 remains on.

The light comes on while you are dri-
ving.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the ªABSº warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the anti±lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(h) ªVSC TRACº Warning Light
This light warns that there is a problem
somewhere in the vehicle stability control
system and traction control system (two±
wheel drive models) or active traction con-
trol system (four±wheel drive models).
The light will come on when the ignition
key is turned to ªONº and will go off after
a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.

sible and check that the inflation pressure
of all tires (including the spare tire) is as
specified on the tire and loading informa-
tion label. (See ªChecking tire inflation
pressureº on page 429 in Section 7±2.)
The light should go off a few minutes after
the tire pressure is adjusted.

miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to the ªONº
position. If you continue driving without
replacing the engine oil, and if the dis-
tance driven exceeds 8000 km (5000
miles), the light will come on after the
