system.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 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, 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 depress the pedal much
harder than normal and the braking dis-
tance will increase.

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.

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.

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
switch is turned to the “LOCK ”/“ OFF ”

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.

steering wheel as described here. When
the vehicle is headed up the hill, the front
wheels should be turned away from the
curb.
When facing downhill, the front wheelsshould be turned into the curb.
Hill start assist system (MT
models)
WARNING
.
The Hill start assist system is a
device only for helping the driver
to START the vehicle on an uphill
grade. To prevent accidents
when the vehicle is parked on a
slope, be sure to firmly set the
parking brake. When setting the
parking brake, make sure that the
vehicle remains stationary when
the clutch pedal and brake pedal
are released.
. Do not turn the ignition switch to
the “LOCK ”/“ OFF ”position while
the Hill start assist system is
operating. The Hill start assist
system will be deactivated, caus-
ing an accident.
The Hill start assist system is a device to
make the following vehicle operations
easier.

Remember that damage done to
your SUBARU while operating it
off-road and not using common
sense precautions such as those
listed above is not eligible for war-
ranty coverage.
Because of the AWD feature and higher
ground clearance, you can drive your
SUBARU on ordinary roads or off-road.
But please keep in mind that an AWD
SUBARU is a passenger car and is
neither a conventional off-road vehicle
nor an all-terrain vehicle. If you do take
your SUBARU off-road, certain common
sense precautions such as those in the
following list should be taken.
! Before driving
. Make certain that you and all of your
passengers are wearing seatbelts.
. Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.
. Secure all cargo carried inside the
vehicle and make certain that it is not
piled higher than the seatbacks. During sudden stops or jolts, unsecured cargo
could be thrown around in the vehicle and
cause injury. Do not pile heavy loads on
the roof. Those loads raise the vehicle’
s
center of gravity and make it more prone
to tip over.
. Never equip your vehicle with tires
larger than those specified in this manual.
! During driving
General precautions:
. Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain.
. Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and
the like.
. Do not drive across steep slopes.
Instead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep.
. Avoid sharp turning maneuvers, espe-
cially at higher speeds.
. Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead,
drive with your fingers and thumbs on
the outside of the rim. .
Do not drive or park over or near
flammable materials such as dry grass or
fallen leaves, as they may burn easily. The
exhaust system is very hot while the
engine is running and right after the
engine stops. This could create a fire
hazard.
Precautions when driving under espe-
cially dangerous situations:
. If driving through water, such as when
crossing shallow streams:
–First, check the depth of the water
and the bottom of the stream bed for
firmness.
– Next, ensure that the bed of the
stream is flat.
– Then, drive slowly and completely
through the stream. The water should
be shallow enough that it does not
reach the vehicle’ s undercarriage.
. Water entering the engine air intake or
the exhaust pipe or water splashing onto
electrical parts may damage your vehicle
and may cause it to stall. Never drive
through rushing water. Regardless of its
depth, it can wash away the ground from
under your tires, resulting in possible loss
of traction and even vehicle rollover.
. If you must rock the vehicle to free it
from sand or mud, depress the accelerator
pedal slightly and move the shift lever/

SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the following
table.
Washer Fluid Con-centration Freezing Temperature
30% 10.4 8F( −12 8C)
50% −48F( −20 8C)
100% −49
8F( −45 8C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
thepipingistoolowfortheoutside
temperature, it may freeze and block the
nozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out- side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.
! Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and
driving dangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has
accumulated under the fenders to avoid
making steering difficult. During severe winter driving, stop when and where it is
safe to do so and check under the fenders
periodically.
!
Parking in cold weather
WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the engine
running.
CAUTION
.Do not use the parking brake
when parking for long periods in
cold weather since it could freeze
in that position.
. When the vehicle is parked in
snow or when it snows, raise the
wiper blades off the glass to
prevent damage to them.
. Under either of the following
conditions, icing may develop
on the brake system, which could
cause poor braking action.
– When the vehicle has been left
parked after use on roads
heavily covered with snow

Driving tips/Trailer towing (Outback)
country on hot days.
. When towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent when compared to normal
operation. You should never
drive at excessive speeds but
always employ extra caution
when towing a trailer. You should
also keep the following tips in
mind.
. When parking on a steep slope
with a trailer attached to your
vehicle, the braking power of the
electronic parking brake may not
be sufficient since strong brak-
ing power is needed.
! Before starting out on a trip
. Check the towing regulations for trailer
or caravan vehicles that vary by state/
region. Failure to comply with the proce-
dures set forth will not only compromise
your safety, but will also negate your
insurance coverage and/or may violate
the state road and traffic acts and regula-
tions.
. Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer. .
Check that the vehicle rests horizon-
tally with the trailer attached. If the vehicle
is tipped sharply up at the front and down
at the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution
are acceptable.
. Check that the tire pressures are
correct.
. Check that the vehicle and trailer are
connected properly. Confirm that
–the trailer tongue is connected
properly to the hitch ball.
– the trailer lights connector is con-
nected properly and trailer ’s stop lights
illuminate when the vehicle’ s brake
pedal is pressed, and that the trailer ’s
turn signal lights flash when the
vehicle’ s turn signal lever is operated.
– the safety chains are connected
properly.
– all cargo in the trailer is secured
safely in position.
– the side mirrors provide a good
rearward field of view without a sig-
nificant blind spot.
. Sufficient time should be taken to learn
the “feel ”of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up. !
Driving with a trailer
. You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may
result in skidding or jackknifing and loss of
control.
. Avoid abrupt starts and sudden accel-
erations. For MT models, always start out
in first gear and release the clutch pedal at
moderate engine revolution.
. Avoid uneven steering, sharp turns and
rapid lane changes.
. Slow down before turning. Make a
longer than normal turning radius because
the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. In
a tight turn, the trailer could hit your
vehicle.
. Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and promptly begin
decelerating your vehicle at a gradual
pace.
. When passing other vehicles, consid-
erable distance is required because of the
added weight and length caused by
attaching the trailer to your vehicle.
