cate any malfunctions, and the brake
assist system is operating properly.
.You might feel that the brake pedal is
applied by lighter force and generates a
greater braking force.
.You might hear an ABS operating
noise from the engine compartment.&Disc brake pad wear warning
indicatorsThe 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 driv-
ing 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 tempera-ture, 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.

heard when depressing the brake pedal
slightly before stopping completely. How-
ever, this does not indicate a malfunction.

ABS (Anti-lock Brake Sys-
tem)The ABS prevents the lock-up of wheels
which may occur during sudden braking or
braking on slippery road surfaces. This
helps prevent the loss of steering control
and directional stability caused by wheel
lock-up.
When the ABS 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 will not operate when the vehicle
speed is below approximately 6 mph (10
km/h).
WARNING
Always use the utmost care in driv-
ing–overconfidence because you
are driving a vehicle with the ABS
could easily lead to a serious acci-
dent.
CAUTION
.The ABS does not always de-
crease stopping distance. You
should always maintain a safe
following distance from other
vehicles.
.When driving on badly surfaced
roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS than
one without. When driving under
these conditions, therefore, re-
duce your speed and leave ample
distance from other vehicles.
.When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do not
pump the brake pedal since
doing so may defeat the opera-
tion of the ABS system.
&ABS self-checkJust 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 being carried out and does not
indicate any abnormal condition.&ABS warning lightRefer to“ABS warning light”F3-20.

Electronic Brake Force Dis-
tribution (EBD) systemThe 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 and uses some of the ABS compo-
nents to perform its function of optimizing
the distribution of braking force. If any of
the ABS components used by the EBD
system malfunction, 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.
&Steps to take if EBD system
malfunctionsBrake and ABS warning lightIf a malfunction occurs in the EBD system,
the system stops working and the brake
system warning light and ABS warning
light illuminate simultaneously.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
while driving.
Even if the EBD system malfunctions, the
conventional braking system will still func-
tion. However, the rear wheels will be more
prone to locking when the brakes are
applied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps.
1. Stop the vehicle in the nearest safe, flat
location.
2. Apply the parking brake and turn off the
engine.
3. Restart the engine.
4. Release the parking brake.
Even if both warning lights turn off:
The EBD system may be malfunctioning.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
If both warning lights illuminate again
and remain illuminated after restarting
the engine:
1. Turn off the engine again.
2. Apply the parking brake.
3. Check the brake fluid level. For details
about checking the brake fluid level, refer
to“Checking the fluid level”F11-24.
.If the brake fluid level is not below the
“MIN”mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
.If the brake fluid level is below the“MIN”
mark, DO NOT drive the vehicle. Instead,
have the vehicle towed to the nearest

should be taken into account
when driving the vehicle in
such a condition.
.If you use non-matching tires, the
Vehicle Dynamics Control sys-
tem may not operate correctly.
.The Vehicle Dynamics Control
system helps prevent unstable
vehicle motion such as skidding
using control of the brakes and
engine power. Do not turn off the
Vehicle Dynamics Control sys-
tem unless it is absolutely neces-
sary. If you must turn off the
Vehicle Dynamics Control sys-
tem, drive very carefully accord-
ing to the road surface condition.
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system
adjusts the engine’s output and the
wheels’respective braking forces to help
maintain traction and directional control.
.Traction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown byflashing the Vehicle Dynamics Control
operation indicator light.
.Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.
Vehicle Dynamics Control operation indi-
cator lightNOTE.The Vehicle Dynamics Control sys-
tem may be considered normal when
the following conditions occur.
–Slight twitching of the brakepedal is felt.
–The vehicle or steering wheel
shakes to a small degree.
–An operating sound from the
engine compartment is heard briefly
when starting the engine and when
driving off after starting the engine.
–The brake pedal seems to jolt
when driving off after starting the
engine.
.In the circumstances shown in the
following list, the vehicle may be less
stable than it feels to the driver. The
Vehicle Dynamics Control System may
therefore operate. Such operation does
not indicate a system malfunction.
–on gravel-covered or rutted roads
–on unfinished roads
–when the vehicle is fitted with
snow tires or winter tires
.Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheelto feel slightly
different compared to that for normal
conditions.
.It is always important to reduce
speed when approaching a corner,
even if your vehicle is equipped with
the Vehicle Dynamics Control system.
.Always turn off the engine before
replacing a tire. Failure to do so may
render the Vehicle Dynamics Control

more than approximately 2 seconds during
engine operation, the mode of the Vehicle
Dynamics Control system will be changed.
!Vehicle Dynamics Control mode
When the ignition switch is on, this mode is
selected first.
This mode enables all controls for ABS,
the Traction Control System, and the
Vehicle Dynamics Control system. Select
this mode for most driving situations.
When this mode is selected, both indicator
lights on the combination meter turn off.!Traction mode
This mode restricts the functions of the
Traction Control System and Vehicle Dy-
namics Control system and thus delays
utilizing their functions as a reaction to
vehicle behavior in comparison with the
Vehicle Dynamics Control mode. Use this
mode in driving situations where the
vehicle dynamic performance will improve
without decreasing engine torque control.
When you press the switch briefly during
engine operation, the traction mode in-
dicator light and the Vehicle Dynamics
Control OFF indicator light on the combi-
nation meter illuminate. When you press
the switch again to reactivate the Vehicle
Dynamics Control system, the traction
mode indicator light and the Vehicle
Dynamics Control OFF indicator light turn
off.
!Vehicle Dynamics Control OFF
mode
This mode allows only the ABS control.
When you press the switch for more than
approximately 2 seconds during engine
operation, the Vehicle Dynamics Control

You should not deactivate the Vehicle
Dynamics Control system except under
the above-mentioned situations.NOTE.If you turn the ignition switch to the
“LOCK”/“OFF”position with the Vehi-
cle Dynamics Control system deacti-
vated, the system will be automatically
reactivated the next time the engine is
started.
.If you press and hold the switch for
30 seconds or longer, the Vehicle
Dynamics Control OFF indicator light
turns off, the Vehicle Dynamics Control
system is activated, and the system
ignores any further pressing of the
switch. To make the switch usable
again, turn the ignition switch to the“LOCK”/“OFF”position and restart the
engine.
.When the Vehicle Dynamics Control
OFF mode is selected, the vehicle’s
running performance is comparable
with that of a vehicle that does not have
a Vehicle Dynamics Control system. Do
not deactivate the Vehicle Dynamics
Control system except when absolutely
necessary.
.Even when the Vehicle Dynamics
Control OFF mode is selected, compo-
nents of the brake control system may
still activate. When the brake control
system is activated, the Vehicle Dy-
namics Control operation indicator
light illuminates.
Tire pressure monitoring
system (TPMS) (U.S.-spec.
models)Low tire pressure warning lightThe tire pressure monitoring system pro-
vides the driver with a warning message by
sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 20 mph (32 km/h). Also, this
system may not react immediately to a
sudden drop in tire pressure (for example,
a blow-out caused by running over a sharp
object).
