when the engine switch is turned to the
ON" 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.
When the hydraulic brake booster
fails...
If the hydraulic booster causes a problem
resulting in poor braking performance, the
warning light comes on and buzzer sounds
continuously. 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 en-
gine switch is in the ON" position.
The light does not come on even if the
engine switch is turned on with the
parking brake released.
A warning light turning on briefly during
operation does not indicate a problem.
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 anti−lock
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 engine switch is
turned to the ON" position. It is nor-
mal 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.

seat belt reminder buzzer be operational
to alert the driver and front passenger that
the seat belts are not fastened.

tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.

the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.

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.

recovered until the engine is stopped and

neous pedal operation.
Emissions inspection and maintenance
