Limited slip differential (LSD)
(STI)The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads or when high speed
driving.
CAUTION
.Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
.If one tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
.If you use a temporary spare tire
to replace a flat tire, be sure to
use the original temporary spare
tire stored in the vehicle. Using
other sizes will adversely affect
the LSD.
Power steering&STIThe vehicle is equipped with a hydraulic
power steering system. The power steer-
ing system operates only when the engine
is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take much
more effort.
CAUTION
Do not hold the steering wheel at the
fully locked position left or right for
more than 5 seconds. This may
damage the power steering pump.NOTERight after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble.

Braking&Braking tips
WARNING
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.
!When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing the
brake pedal to heat up the brakes.
!Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To help
prevent this, shift into a lower gear to get
stronger engine braking.
!Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could causea loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe place.
&Brake system!Two separate circuits
Your vehicle has two separate circuit brake
systems. Each circuit works diagonally
across the vehicle. If one circuit of the
brake system should fail, the other half of
the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.
!Brake booster
The brake booster uses engine manifold
vacuum to assist braking force. Do not turn
off the engine while driving because that
will turn off the brake booster, resulting in
poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to depress the pedal much harder
than normal and the braking distance will
increase.!Brake assist system
WARNING
Do not be overconfident about the
brake assist. It is not a system that
brings more braking ability to the
vehicle beyond its braking capabil-
ity. Always use the utmost care
when driving regarding vehicle
speed and safe distance.
CAUTION
When you need to brake suddenly,
continue depressing the brake pedal
strongly to obtain the effect of the
brake assist.
Brake assist is a driver assistance system.
It assists the brake power when the driver
cannot depress the brake pedal strongly
and the brake power is insufficient.
Brake assist generates the brake power
according to the speed at which the driver
depresses the brake pedal.NOTEWhen you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi-

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.
&Red caliper with sports brake
pad (if equipped)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.
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.

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

ing brake due to, for example, a system
malfunction, contact your SUBARU
dealer and have your SUBARU dealer
release the parking brake.
.If you stop operating the electronicparking brake switch midway or oper-
ate extremely slowly, the system may
detect an error and turn on the brake
system warning light. However, this
does not indicate a malfunction if the
brake system warning light turns off
after operating the switch.
.When the electronic parking brake
has not been used for a long period of
time, the electronic parking brake may
operate automatically after the ignition
switch is turned to the“LOCK”/“OFF”
position. This occurs due to checking
the proper operation of the electronic
parking brake and does not indicate a
malfunction.
