Starting and operating/Braking
cate any malfunctions, and the brake
assist system is operating properly.
. You might feel that the brake pedal
is applied by lighter force and gener-
ates a greater braking force.
. You might hear an ABS operating
noise from the engine compartment.
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, im-
mediately have your vehicle checked by
your SUBARU dealer.
High performance brake sys-
tem (STI)
Your vehicle is equipped with large, high
performance brake pads that provide
optimum braking force under various
driving conditions. The brake pads have
the following characteristics.
Brake noises
The brake pads are made of iron-based
material. Therefore, unusual noise may be
heard when depressing the brake pedal
slightly before stopping completely. How-
ever, this does not indicate a malfunction.
Discoloration
Frequent severe driving, such as repeated
driving on sharp uphill or downhill grades,
can cause discoloration of the paint on the
brake calipers. The discoloration will not
affect the braking performance.
Stuck brake pads
. If the vehicle is left parked for an
extended period of time with the brake
system wet, the iron in the brake pads
may form rust and cause the brake pads
and disc rotors to stick together. This may
result in noise or vibration while driving. If
this occurs, fully depress the brake pedal
several times to free the brake pads.
. If the vehicle is left parked for an
extended period of time in a cold tem-
perature, the brake pads and disc rotors
may be frozen and stuck together. In this
case, it may be difficult to start the vehicle.
Brake dust
Due to the material used for the brake
pads, the wheels may become covered in
brake dust. This is not a malfunction, and
will not affect the brake performance.
