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.

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

SUBARU dealer for repair.
WARNING
.Driving with the brake system
warning light illuminated is dan-
gerous. This indicates your brake
system may not be working prop-
erly. If the light remains illumi-
nated, have the brakes inspected
by a SUBARU dealer immedi-
ately.
.If at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.
Vehicle Dynamics Control
system
WARNING
Always use the utmost care in driv-
ing–overconfidence because you
are driving a vehicle with the Vehicle
Dynamics Control system could ea-
sily lead to a serious accident.
CAUTION
.Even if your vehicle is equipped
with Vehicle Dynamics Control
system, winter tires should be
used when driving on snow-cov-
ered or icy roads; in addition,
vehicle speed should be reduced
considerably. Simply having a
Vehicle Dynamics Control sys-
tem does not guarantee that the
vehicle will be able to avoid
accidents in any situation.
.Activation of the Vehicle Dy-
namics Control system is an
indication that the road being
travelled on has a slippery sur-
face; since having Vehicle Dy-
namics Control is no guaranteethat full vehicle control will be
maintained at all times and under
all conditions, its activation
should be seen as a sign that
the speed of the vehicle should
be reduced considerably.
.Whenever suspension compo-
nents, steering components, or
an axle are removed from a
vehicle, have an inspection of
that system performed by an
authorized SUBARU dealer.
.Observe the following precau-
tions in order to ensure that the
Vehicle Dynamics Control sys-
tem is operating properly:
–Fit all four wheels with tires of
the same size, type, and
brand. Furthermore, the
amount of wear should be the
same for all four tires.
–Keep the tire pressure at the
proper level as shown on the
vehicle placard attached to
the driver’s side door pillar.
–Use only the specified tempor-
ary spare tire to replace a flat
tire. With a temporary spare
tire, the effectiveness of the
Vehicle Dynamics Control
system is reduced and this

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

Creating an adequate driving wheel slip by
deactivating the Vehicle Dynamics Control
system temporarily may help to escape
from the following situations. Use the
Vehicle Dynamics Control OFF mode as
necessary.

road with a snowy, gravel-covered, or
otherwise slippery surface
.extrication of the vehicle when its
wheels are stuck in mud or deep snow
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).

WARNING
.If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
Otherwise, an accident involving
serious vehicle damage and ser-
ious personal injury could occur.
(1) Keep driving straight ahead
while gradually reducing
speed.
(2) Slowly pull off the road to a
safe place.
(3) Check the pressure for all four
tires and adjust the pressure
to the COLD tire pressure
shown on the vehicle placard
on the door pillar on the
driver’s side.
Even when the vehicle is driven a
very short distance, the tires get
warm and their pressures in-
crease accordingly. Be sure to
let the tires cool thoroughly be-
fore adjusting their pressures to
the standard values shown on the
tire placard. Refer to“Tires and
wheels”F11-30. The tire pres-
sure monitoring system does not
function when the vehicle is sta-tionary. After adjusting the tire
pressures, increase the vehicle
speed to at least 20 mph (32 km/h)
to start the TPMS rechecking of
the tire inflation pressures. If the
tire pressures are now above the
severe low pressure threshold,
the low tire pressure warning
light should turn off a few min-
utes later.
If this light still illuminates while
driving after adjusting the tire
pressure, a tire may have signifi-
cant damage and a fast leak that
causes the tire to lose air rapidly.
If you have a flat tire, refer to“Flat
tires”F9-5.
.When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/trans-
mitter being transferred, the low
tire pressure warning light will
illuminate steadily after blinking
for approximately one minute.
This indicates the TPMS is unable
to monitor all four road wheels.
Contact your SUBARU dealer as
soon as possible for tire and
sensor replacement and/or sys-
tem resetting.
.When a tire is repaired with liquid
sealant, the tire pressure warningvalve and transmitter may not
operate properly. If a liquid sea-
lant is used, contact your nearest
SUBARU dealer or other qualified
service shop as soon as possi-
ble. Make sure to replace the tire
pressure warning valve and
transmitter when replacing the
tire. You may reuse the wheel if
there is no damage to it and if the
sealant residue is properly
cleaned off. Do not inject any tire
liquid or aerosol tire sealant into
the tires, as this may cause a
malfunction of the tire pressure
sensors. If the light illuminates
steadily after blinking for ap-
proximately one minute,
promptly contact a SUBARU
dealer to have the system in-
spected.
CAUTION
Do not place metal film or any metal
parts in the trunk. This may cause
poor reception of the signals from
the tire pressure sensors, and the
tire pressure monitoring system will
not function properly.

headed up the hill, turn the front wheels
away from the curb.When facing downhill, turn the front
wheels into the curb.
WARNING
.Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to people.
.Do not park the vehicle overflammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
.Be sure to stop the engine if you
take a nap in the vehicle. If engine
exhaust gas enters the passen-
ger compartment, occupants in
the vehicle could die from carbon
monoxide (CO) contained in the
exhaust gas.
CAUTION
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), pay attention to blocks
and other obstructions on the
ground when parking. The under-
spoilers could be damaged by con-
tact with them.
Auto Vehicle Hold functionThe Auto Vehicle Hold function will auto-
matically keep the vehicle stopped even
after releasing the brake pedal when the
vehicle is at a complete stop, such as at
traffic signals. The function will be can-
celed by either of the following operations.
.Depressing the accelerator pedal
.Depressing the brake pedal again
WARNING
.Do not use the Auto Vehicle Hold
function on a steep hill or slip-
pery road. The vehicle may move
even when using the Auto Vehicle
Hold function, causing serious
injury or accidents.
.Do not use the Auto Vehicle Hold
function to park the vehicle. The
vehicle may move unexpectedly,
causing serious injury or acci-
dents. Make sure to shift the
