Starting and operating
Disc brake pad wear warning
indicators
The disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, imme-
diately have your vehicle checked by your
SUBARU dealer.
ABS (Anti-lock Brake Sys-
tem)
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
Just after the vehicle is started, you may
feel on the brake pedal a vibration similar
to when the ABS operates, and you may
also hear the sound of the ABS working
from the engine compartment. This is
caused by an automatic functional test of
the ABS system being carried out and

Always use the utmost care in driv-
ing – overconfidence because you
are driving with an ABS equipped
vehicle could easily lead to a seri-
ous accident.
The ABS system does not always
decrease stopping distance. You
should always maintain a safe fol-
lowing distance from other vehi-
cles.
When driving on badly surfaced
roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be longer
for a vehicle with the ABS system
than one without. When driving
under these conditions, therefore,
reduce your speed and leave am-
ple distance from other vehicles.
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.
