Power steering
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.
The power steering 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. NOTE
Right 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 cause a 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 a dual circuit brake
system. 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 thevehicle. ! 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, result-
ing 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 push the pedal much harder
than normal and the braking distance willincrease.

&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 inspected by
the nearest SUBARU dealer. ABS (Anti-lock Brake Sys- tem)
WARNING
Always use the utmost care in driving –overconfidence because
youaredrivingwithanABS
equipped vehicle could easily lead
to a serious accident.
CAUTION
. The ABS system does not always
decrease stopping distance. You
should always maintain a safe
following distance from othervehicles.
. When driving on badly surfaced
roads, gravel roads, icy road, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS
system than one without. When
driving under these conditions,
therefore, reduce your speed and
leave ample distance from othervehicles.
. 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
operation of the ABS system.
The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road sur-
faces. 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
You may feel a slight shock in the brake
pedal and hear the operating sound of
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
system being carried out and does not
indicate any abnormal condition. Starting and operating

&ABS warning light
Vehicle with SI-DRIVE
Vehicle without SI-DRIVE
The ABS warning light illuminates when
the ignition switch is turned to the “ON ” position and goes out after approximately
2 seconds.
This is an indication that the ABS system
is working properly.
CAUTION
If the warning light behaves as
follows, the ABS system may not
be working properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally. . The warning light does not illu-
minates when the ignition switch
is turned to the “ON ”position.
. The warning light illuminates
when the ignition switch is
turned to the “ON ”position, but
it does not go out even when the
vehicle speed exceeds approxi-
mately 8 mph (12 km/h).
. The warning light illuminates dur-
ing driving.
If these occur, have the ABS system
repaired at the first available oppor-
tunity by your SUBARU dealer. NOTE
If the warning light behavior is as
described in the following, the ABS
system may be considered normal. .
The warning light illuminates right
after the engine is started but goes out
immediately, remaining off.. The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h).. The warning light illuminates during
driving, but it goes out immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may illumi-
nate. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out.

Electronic Brake Force Dis-
tribution (EBD) system
The 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 system and uses some of the ABSsystem ’s components to perform its func-
tion of optimizing the distribution of brak-
ing force. If any of the ABS components
used by the EBD function fails, 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 fails
Vehicle with SI-DRIVE
Vehicle without SI-DRIVE
If 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 faulty if the
brake system warning light and ABS
warning light illuminate simultaneously
during driving.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are
applied harder than usual and the vehi-cle
’s motion may therefore become some-
what 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 place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both
warning lights go out, the EBD system
may be faulty.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
4. If both warning lights illuminate again
and stay illuminated after the engine has
been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.

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.
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 by
steady illumination of the Vehicle Dy-
namics 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. NOTE .
Slight twitching of the brake pedal
may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or steering wheel shak-
ing may also be noticed in this situa-
tion. These are normal characteristics
of Vehicle Dynamics Control operation
and are no cause for alarm.. When driving off immediately after
starting the engine, a short-lived opera-
tion noise may be noticed coming from
the engine compartment. This noise is
generated as a result of a check being
performed on the Vehicle Dynamics
Control system and is normal.. Depending on the timing of activa-
tion of the brakes, the brake pedal may
seem to jolt when you drive off after
starting the engine. This is a conse-
quence of the Vehicle Dynamics Con-
trol operational check and is normal.. In the circumstances shown in the
following list, the vehicle may be more
unstable than it feels to the driver. The
Vehicle Dynamics Control System may
therefore operate. Such operation does
not indicate a system fault.
–on gravel-covered or rutted
roads – on unfinished roads
– when the vehicle is towing a trailer–
when the vehicle is fitted with
snow tires or winter tires
. Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheel to feel slightly
different compared to that for normalconditions. . Even if the vehicle is equipped with
a Vehicle Dynamics Control system, it
is important that winter tires be used
when driving on snow-covered or icy
roads. (All four wheels should be fitted
with tires of the same size and brand.)
Furthermore, if snow chains are to be
used, they should be fitted on the front
wheels. When a vehicle is fitted with
snow chains, however, the effective-
ness of the Vehicle Dynamics Control
system is reduced and this should be
taken into account when driving the
vehicle in such a condition. . It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with
Vehicle Dynamics Control. . All four wheels should be fitted with
tires of the same size, type, and brand;
furthermore, the amount of wear
should be the same for all four tires. If
these precautions are not observed
and non-matching tires are used, it is Starting and operating

quite possible that the Vehicle Dy-
namics Control system will be unable
to operate correctly as intended. . Always turn off the engine before
replacing a tire as failure to do so may
render the Vehicle Dynamics Control
system unable to operate correctly. & Vehicle Dynamics Control

This indicator light flashes during activa-
tion of the skid suppression function and is
illuminated steadily during activation of the
traction control function.
The following two situations could indicate
a malfunction of the Vehicle Dynamics

have an authorized SUBARU dealer carry
out an inspection of that system at the first
available opportunity. . The indicator light does not turn on

This single light has the function of
indicating malfunctions in the Vehicle
Dynamics Control system and the function
of indicating that the Vehicle Dynamics
Control system is not operating. It illumi-
nates in the event of a malfunction in the
system and is illuminated whenever the
system is not operating. !Vehicle Dynamics Control warning
The warning light illuminates when the
ignition switch is turned to the “ON ”
position and goes off several seconds
after engine startup. This lighting pattern
indicates that the Vehicle Dynamics Con-
trol system is operating normally.
The following situations could indicate a
malfunction of the Vehicle Dynamics
Control system; if any should occur, have
an authorized SUBARU dealer carry out
an inspection of the system at the first
available opportunity. . The warning light does not turn on
when the ignition switch is turned to the
ON position. . The warning light turns on while the
vehicle is being driven.. When a malfunction has occurred in
the Vehicle Dynamics Control electrical
system, only the warning light will turn on.
In such an event, the ABS will still be
operating normally. .
The warning light will also turn on when
a problem occurs with the ABS or Vehicle
Dynamics Control electronic control sys-tems.
Because the Vehicle Dynamics Control
system controls each brake through the
ABS, whenever the ABS stops operating
due to a malfunction in that electrical
system, the Vehicle Dynamics Control will
also become unable to control all four
brakes. Thus Vehicle Dynamics Control
system operation halts and the warning
light turns on. Although both the Vehicle
Dynamics Control system and the ABS
will be inoperable in this situation, it will
still be possible to stop the vehicle using
normal braking. The Vehicle Dynamics
Control system and the ABS do not
adversely affect operation of the vehicle
in any way when they are inoperable;
however should such a situation occur,
drive with care and have an authorized
SUBARU dealer carry out an inspection of
those systems at the first available oppor-
tunity. NOTE
When the warning light turns on and off
in the following way, it indicates that
the Vehicle Dynamics Control system
is operating normally. . Although turning on after the engine has been started, the warning light
quickly turns off and stays off..
The warning light turns on when the
vehicle is being driven; it then turns off
and stays off. ! Vehicle Dynamics Control OFF in-
dicator light
This light illuminates to indicate that the
Vehicle Dynamics Control system is in
non-operation mode. This does not con-
stitute failure of the Vehicle Dynamics
Control system. NOTE . The indicator light may stay on for a
while after the engine has been started,
especially in cold weather. This occurs
because the engine has not yet
warmed up and is completely normal.
The light will turn off when the engine
has reached a suitable operating tem-perature.. When an engine problem occurs
and the CHECK ENGINE warning light/
malfunction indicator lamp turns on,
the indicator light will also illuminate.

otherwise slippery surface . extrication of the vehicle when its wheels are stuck in mud or deep snow
When the switch is pressed during engine
operation, the

cle Dynamics Control system will be
deactivated and the vehicle will behave
like a model not equipped with the Vehicle

With the Vehicle Dynamics Control system
deactivated, traction and stability en-
hancement offered by Vehicle Dynamics

you should not deactivate the Vehicle
Dynamics Control system except under
above-mentioned situations. NOTE . When the switch has been pressed
to deactivate the Vehicle Dynamics
Control system, the Vehicle Dynamics
Control system automatically reacti-
vates itself the next time the ignition
switch is turned to the “LOCK ”position
and the engine is restarted.. If the switch is held down for 10
seconds or longer, the indicator light
goes 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“
