Abs System Self-Check; Abs Warning Light - Subaru A3100BE Owner's Manual

When you feel the ABS system
operating, you should maintain
constant brake pedal pressure.
Do not pump the brake pedal
since doing so may defeat the op-
eration of the ABS system.
The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road surfac-
es. This helps prevent the loss of steering
control and directional stability caused by
wheel lock-up.
When the ABS system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
when the ABS operates.
The ABS system will not operate when the
vehicle speed is below approximately 6
mph (10 km/h).

ABS system self-check

You may feel a slight shock in the brake
pedal and hear the operating sound of
ABS from the engine compartment just af-
ter the vehicle is started. This is caused by
an automatic functional test of the ABS
system being carried out and does not in-
dicate any abnormal condition.

ABS warning light

The ABS warning light comes on when the
ignition switch is turned to the "ON" posi-
tion and goes out after approximately two
seconds.
This is an indication that the ABS system
is working properly.
If the warning light behaves as fol-
lows, 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.
Starting and operating
The warning light does not come
on when the ignition switch is
turned to the "ON" position.
The warning light comes on when
the ignition switch is turned to the
"ON" position, but it does not go
out even when the vehicle speed
exceeds approximately 8 mph (12
km/h).
The warning light comes on dur-
ing driving.
If these occur, have the ABS system
700314
repaired at the first available oppor-
tunity by your SUBARU dealer.
NOTE
If the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal.
The warning light comes on right af-
ter the engine is started but goes out
immediately, remaining off.
The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h).
The warning light comes on during
driving, but it goes out immediately
and remains off.
