Starting and operating
CAUTION
If the warning light behaves as
described below, the ABS system
may not be working properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally.
. The warning light does not illu-
minate when the ignition switch
is turned to the "ON" position.
. The warning light illuminates
when the ignition switch is
turned to the "ON" position, but
it does not turn off even when the
vehicle speed exceeds approxi-
mately 8 mph (12 km/h).
. The warning light illuminates dur-
ing driving.
If these occur, have the ABS system
repaired at the first available oppor-
tunity by your SUBARU dealer.

the engine has been started, but it
turns off when the vehicle speed

Electronic Brake Force Dis-
tribution (EBD) system
The EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of
the braking force. It functions by adjusting
the distribution of braking force to the rear
wheels in accordance with the vehicle's
loading condition and speed.
The EBD system is an integral part of the
ABS system and uses some of the ABS
system's components to perform its func-
tion of optimizing the distribution of brak-
ing force. If any of the ABS components
used by the EBD function fail, the EBD
system also stops working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction.
