(a) Brake System Warning Light and
Buzzer
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
! When the parking brake is applied...
This light comes on for a few seconds
when the ignition key is turned to the
“ON” position on 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 igni-
tion key is in the “ON” 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 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 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.
