!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 bring 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.
NOTE
When 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 gener-
ates a greater braking force.
. You might hear the sound of ABS
operating from the engine compart-
ment.
& 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
you are driving with an ABS
equipped vehicle could easily lead
to a serious accident.
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 road, 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
Starting and operating/ABS (Anti –lock Brake System)
–CONTINUED –7-33

Starting and operating/Electronic Brake Force Distribution (EBD) system
pump the brake pedal since
doing so may defeat the opera-
tion of the ABS.
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).
& ABS self-check
You may feel a slight shock in the brake
pedal and hear the operating noise of the
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
being carried out and does not indicate
any abnormal condition.
&ABS warning light
Refer to “ABS warning light ”F 3-19.
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 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
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
malfunctions
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 malfunctioning 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.
7-34

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 ”F 11-20.
. 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 on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
. If at all in doubt about whether
the brakes are operating prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re-
pair.
Vehicle Dynamics Control
system
WARNING
Always use the utmost care in
driving –overconfidence because
you are driving with a Vehicle Dy-
namics Control system equipped
vehicle could easily lead to a ser-
ious 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-

Starting and operating/Vehicle Dynamics Control system
namics Control is no guarantee
that 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 equipped with the Vehicle
Dynamics Control system, have
an inspection of that system
performedbyanauthorized
SUBARU dealer.
. The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Con-
trol system is operating properly.
– All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, 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 tem-
porary spare tire to replace a flat tire. With a temporary
spare tire, the effectiveness
of the Vehicle Dynamics Con-
trol system is reduced and
this should be taken into ac-
count when driving the vehi-
cle in such a condition.
. If non-matching tires are used,
the Vehicle Dynamics Control
system may not operate cor-
rectly.
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 indicated by
flashing of 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 slidesideways during steering operations. Acti-
vation of this function is indicated by
flashing of the Vehicle Dynamics Control
operation indicator light.
NOTE
.
The Vehicle Dynamics Control sys-
tem may be considered normal when
the following conditions occur.
–Slight twitching of the brake
pedal is felt.
– The vehicle or steering wheel
shakes to a small degree.
– An operating noise from the en-
gine 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 following circumstances, 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 towing a
trailer
– when the vehicle is fitted with
7-36

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 normal
conditions.
. It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with
Vehicle Dynamics Control.
. 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
OFF switch
Pressing the Vehicle Dynamics Control
OFF switch deactivates the Vehicle Dy-
namics Control system.
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 switch as
necessary.
. a standing start on a steeply sloping
road with a snowy, gravel-covered, or
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 Vehicle Dynamics Control
OFF indicator light on the combination
meter illuminates. The Vehicle Dynamics
Control system will be deactivated. When
the switch is pressed again to reactivate
the Vehicle Dynamics Control system, the
Vehicle Dynamics Control OFF indicator
light turns off.
You should not deactivate the Vehicle
Dynamics Control system except under
the above-mentioned situations.
CAUTION
The Vehicle Dynamics Control sys-
tem helps prevent unstable vehicle
motion such as skidding using con-
trol of the brakes and engine power.
Do not turn off the Vehicle Dynamics
Control system unless it is abso-
lutely necessary. If you must turn off
the Vehicle Dynamics Control sys-
tem, drive very carefully based on
the road surface condition.
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

els)
WARNING
. Always use the utmost care in
driving –overconfidence be-
cause you are driving a vehicle
with X-mode could easily lead to
a serious accident.
. Always use the utmost care in
driving –overconfidence be-
cause you are driving a vehicle
with hill descent control function
could easily lead to a serious
accident. Be especially careful,
and depress the brake pedal if
necessary when driving on ex-
tremely steep downhill, frozen,
muddy or sandy roads. Failure
to control the vehicle ’sspeed
may cause a loss of control and
result in a serious accident.
CAUTION
. Even if your vehicle is equipped
with X-mode, winter tires should
be used when driving on snow-
covered or icy roads; in addition,
vehicle speed should be reduced considerably. Simply having X-
mode does not guarantee that
the vehicle will be able to avoid
accidents in any situation.
. Activate the X-mode when you
encounter a very slippery surface
at low speed. However, having X-
mode is no guarantee that full
vehicle control will be maintained
at all times and under all condi-
tions. When activating X-mode,
the speed of the vehicle should
be reduced considerably.
. Whenever suspension compo-
nents, steering components, or
an axle are removed from a
vehicle, have the system in-
spected by an authorized
SUBARU dealer.
. Observe the following precau-
tions in order to ensure that the
X-mode is operating properly:
– All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, the amount of wear
should be the same for all
four tires.
– Keep the tire pressure at the
proper level as shown on the
label attached to the vehicle ’s
7-38

door pillar.
– Use only the special tempor-
ary spare tire to replace a flat
tire. With a normal temporary
spare tire, the effectiveness of
the X-mode is reduced and
this should be taken into ac-
count when driving the vehi-
cle in such a condition.
. If the hill descent control function
has operated continuously for a
long time, the temperature of the
brake disc may increase and the
hill descent control function may
be temporarily disabled. In this
case, the hill descent control
indicator will disappear. When
the hill descent control indicator
disappears, the hill descent con-
trol function is disabled.
X-mode is the integrated control system of
the engine, AWD and Vehicle Dynamics
Control system, etc. for driving with bad
road conditions. Using X-mode, you can
drive more comfortably even in slippery
road conditions including uphill and down-
hill. X-mode has the following functions.
.
Hill descent control function:
Using the hill descent control function, you
can keep the vehicle at a consistent speed
driving downhill. If the vehicle speed is
likely to increase, the brake control system
will be activated to adjust the vehicle
speed.
. Driving ability control:
This mode increases the hill-climbing
ability and driving ability as well as
enabling smooth application of torque for
easier control of the steering wheel.

minates.
– The AT OIL TEMP warning light
flashes.
– The ABS warning light illumi-
nates.
– The Vehicle Dynamics Control
warning light illuminates.
. If the engine could overheat be-
cause of a temperature increase of the
engine coolant, it may not be possible
to activate the X-mode. Even while the
X-mode is activated, the X-mode will be
deactivated when the engine coolant
temperature increases.
& Hill descent control function
The hill descent control function will be in
standby mode when the X-mode is acti-
vated and the vehicle speed is less than
approximately 12 mph (20 km/h).
The function will operate when the vehicle
speed is less than approximately 12 mph (20 km/h) and the accelerator ratio is less
than approximately 10%.
The function will turn off when the vehicle
speed is more than approximately 12 mph
(20 km/h) and the accelerator pedal is
depressed.
CAUTION
The braking power of the hill des-
cent control function may not be
sufficient when strong braking
power is needed (e.g., when towing
a trailer (Outback)).
NOTE
.
Even while the hill descent control
function is operating, you can vary the
vehicle speed by using the brake pedal
or accelerator pedal.
. During braking by the hill descent
control function, the hill descent con-
trol indicator will flash.
. The hill descent control function is
operable regardless of the gradient of
the road.
. The hill descent control function
may be considered normal when the
following conditions occur.
–An operating sound is heard
briefly from the engine compart-
ment while the hill descent control function is operating.
–
The sensation of depressing the
brake pedal is different, (harder
than usual etc.) when the brake
pedal is depressed during hill des-
cent control function operation.
! Hill descent control indicator
This indicator appears while the hill
descent control function is in the standby
mode. It flashes while the function is
operating. It will disappear when the
function is in the disabled mode. When
this function is changed from operational
to non-operational, it will disappear when
the vehicle speed reaches more than
approximately 18 mph (30 km/h).
