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

–Use tire stops under the tires
to prevent the vehicle from
moving.
.Never drive with the parking
brake applied. Doing so will
cause unnecessary wear on the
brake linings. Before driving off,
always make sure that the park-
ing brake has been released and
the brake system warning light
has turned off.
Your vehicle is equipped with an electronic
parking brake. You can apply/release the
parking brake by operating the parking
brake switch.
To apply:Depress the brake pedal and
pull up the parking brake switch.
To release:Press the parking brake
switch firmly while the ignition switch is in
the“ON”position and the brake pedal is
depressed.
When the parking brake is applied while
the ignition switch is in the“ON”position,
the electronic parking brake indicator light
and the indicator light on the parking brake
switch illuminate. Refer to“Brake system
warning light”F3-21.
NOTE.If you press the parking brake switch
under the following conditions, the
parking brake will not be released.
–The ignition switch is in the
“ACC”or“LOCK”/“OFF”position.
–You are not depressing the brake
pedal.
.The electronic parking brake system
uses motors to apply the parking brake.
Therefore, operating sounds from the
motors will be heard when applying or
releasing the parking brake. Make sure
that the motor sounds are heard when
applying or releasing the parking
brake.
.If you operate the parking brake
switch under the following conditions,
a chirp will sound and the electronic
parking brake indicator light will flash.
–when the electronic parking
brake system has a malfunction
–when the electronic parking
brake operation is prohibited tem-
porarily
.When you cannot release the park-
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.
.If you cannot release the electronic
parking brake due to the switch mal-
function, refer to the instructions de-
scribed in“Automatic release function
by accelerator pedal”F7-45.
After activating the electronic parking
brake, you may hear a short sound
several minutes after the electronic
parking brake indicator light illumi-
nates as the system confirms proper
engagement. This sound is different
from the apply and release sound.
This can occur:
–If the brakes are extremely hot.
–If the car is parked on a steep
incline.

aligned, a system malfunction
may occur, including the inability
to detect vehicles entering the
detection areas. If any strong
shock is applied to the bumper,
be sure to contact your SUBARU
dealer for inspection.
–Do not disassemble the radar
sensors.
NOTEIf the radar sensors require repair or
replacement, or the bumper area
around the radar sensors requires
repair, paintwork or replacement, con-
tact your SUBARU dealer for assis-
tance.
Reverse Automatic Braking
System (if equipped)Reverse Automatic Braking is a system
designed to help avoid collisions or reduce
collision damage when reversing the
vehicle. If a wall or an obstacle is detected
in the reversing direction, the system will
notify the driver with a warning sound and
may activate the vehicle’s brakes auto-
matically.
WARNING
.Reverse Automatic Braking is not
a system intended to replace the
driver’s responsibility to check
surrounding areas for vehicles or
obstacles to avoid a collision.
.The driver is responsible for driv-
ing safely. Always be sure to
check the surroundings visually
when reversing the vehicle.
.There are some cases in which
the vehicle cannot avoid colli-
sion, because the system opera-
tion has limitations. The warning
sound or automatic braking may
be delayed or may not operate at
all even when an obstacle is
present..The system is not designed to
detect people (including chil-
dren), animals or other moving
objects.
.Depending on the vehicle condi-
tion or the surrounding environ-
ment, the sonar sensor’s ability
to detect objects may become
unstable.
NOTEThe Reverse Automatic Braking Sys-
tem records and stores the following
data when automatic braking operates.
It does not record conversations, per-
sonal information or other audio data.
.Distance from the object
.Vehicle speed
.Accelerator pedal operation status
.Brake pedal operation status
.Select lever position
.Outside temperature

not disclose or provide the acquired
data to any other third party except
under the following conditions.
–The vehicle owner has given his/
her consent.
–The disclosure/provision is
based on a court order or other
legally enforceable request.
–Data that has been modified so
that the user and vehicle cannot be
identified is provided to a research
institution for statistical processing
or similar purposes.
&Reverse Automatic Braking
System overviewThe system detects objects using sonar
sensors installed in the rear bumper. If the
system determines a possible collision
with an object in the reversing direction,
automatic deceleration will be activated.
Also, beeping sounds will activate. If the
vehicle is further reversed, automatic hard
braking will be applied and a continuous
beeping sound will activate.!Detecting range
1) Detecting range (width): Approximately 6
in (15 cm) outside of the vehicle width
2) Range that the system cannot detect:
Approximately 20 in (50 cm) behind the
rear of the vehicle
3) Detecting range (length): Approximately
5 ft (1.5 m) from the rear of the vehicle
WARNING
If your vehicle is trapped on a rail-
road crossing and you are trying to
escape by reversing through the
crossing gate, the system may re-
cognize the crossing gate as an
obstacle and the brakes may acti-
vate. In this case, remain calm and
either continue to depress the accel-
erator pedal or cancel the system. Tocancel the system, refer to“Cancel-
ing the Reverse Automatic Braking
system operation”F7-74.

–When the vehicle has been left
parked during a snowstorm
Check for snow or ice buildup on
the suspension, disc brakes and
brake hoses underneath the ve-
hicle. If there is caked snow or
ice, remove it, being careful not
to damage the disc brakes and
brake hoses and ABS harness.
When parking for long periods in cold
weather, you should observe the following
tips.
1. For MT models, place the shift lever in
the“1”or“R”position. For CVT models,
place the select lever in the“P”position.
2. Use tire stops under the tires to prevent
the vehicle from moving.
!Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an anti-
freeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used for
an extended period, it is best to have thefuel tank filled to capacity.
&Driving on snowy and icy
roadsTo prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle’s braking perfor-
mance on snowy and icy roads. For
information on braking on slippery sur-
faces, refer to“ABS (Anti-lock Brake
System)”F7-35 and“Vehicle Dynamics
Control system”F7-37.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of vehi-
cle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine’sintakesystemandmay
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
!Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blade rubbers are not frozen to
the windshield.
If the wiper blade rubbers are frozen to the
windshield, use the defroster and the
temperature set for maximum warmth until
the wiper blade rubbers are completely
thawed. Refer to“Climate control”F4-1.
If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blade rubbers. Refer to
“Defogger and deicer”F3-84.

Exterior care&Washing
CAUTION
TYPE RA: Do not use automatic car
washes. Doing so may damage the
rear wing or its finish.
CAUTION
.When washing the vehicle, the
brakes may get wet. As a result,
the brake stopping distance will
be longer. To dry the brakes, drive
the vehicle at a safe speed while
lightly depressing the brake ped-
al to heat up the brakes.
.Do not wash the engine compart-
ment and area adjacent to it. If
water enters the engine air intake
or electrical parts, it will cause
engine trouble or a malfunction
of electrical equipment.
.When washing the inner fenders,
underbody, bumpers and pro-
truding objects such as exhaust
pipes and exhaust finishers, be
careful to prevent injuries from
contacting sharp ends..Do not use any organic solvents
when washing the surface of the
bulb assembly cover. However, if
a detergent with organic solvents
is used to wash the cover sur-
face, completely rinse off the
detergent with water. Otherwise,
the cover surface may be da-
maged.
NOTEWhen having your vehicle washed in an
automatic car wash, make sure before-
hand that the car wash is of suitable
type.
The best way to preserve your vehicle’s
beauty is frequent washing. Wash the
vehicle at least once a month to avoid
contamination by road grime.
Wash dirt off with a wet sponge and plenty
of lukewarm or cold water. Do not wash the
vehicle with hot water and in direct sun-
light.
Salt, chemicals, insects, tar, soot, tree sap,
and bird droppings should be washed off
by using a light detergent, as required. If
you use a light detergent, make certain
that it is a neutral detergent. Do not use
strong soap or chemical detergents. All
cleaning agents should be promptly rinsedoff the surface and not allowed to dry there.
Rinse the vehicle thoroughly with plenty of
lukewarm water. Wipe the remaining water
off with a chamois or soft cloth. Wear
rubber gloves and use a hand brush when
washing down underbody, inner fenders
and suspension to effectively remove mud
and dirt off.
!Washing the underbody
Chemicals, salts and gravel used for
deicing road surfaces are extremely cor-
rosive, accelerating the corrosion of un-
derbody components, such as the exhaust
system, fuel and brake lines, brake cables,
floor pan and fenders, and suspension.
Thoroughly flush the underbody and inside
of the fenders with lukewarm or cold water
at frequent intervals to reduce the harmful
effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or on muddy or sandy
roads, wash the mud and sand off the
underbody. Carefully flush the suspension
and axle parts, as they are particularly
prone to mud and sand buildup. Do not use
a sharp-edged tool to remove caked mud.
