&Except STIPower steering warning lightThe vehicle is equipped with an electric
power steering system. The power steer-
ing system operates only while the engine
is running. When you turn the ignition
switch to the“ON”position, the power
steering warning light on the combination
meter illuminates to inform the driver that
the warning system is functioning properly.
Then, if the engine started, the warning
light turns off to inform the driver that the
steering power assist is operational.
CAUTION
While the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.NOTEIf you operate the steering wheel in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent the
system components, such as the con-
trol computer and drive motor, from
overheating.
.You operate the steering wheel fre-
quently and turn it sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently turn-
ing the steering wheel during parallel
parking.
.You keep the steering wheel in the
fully turned position for a long period of
time.
At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
force will be restored after the steeringwheel is not operated for a while and
the power steering control system has
an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes power
assist limitation to occur too frequently,
this may result in a malfunction of the
power steering control 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 causea 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 two separate circuit brake
systems. 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, resulting 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 distance will
increase.!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 obtain 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.NOTEWhen you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi-

–If the electronic parking brake is
applied after the ignition switch is
turned OFF.
This is a normal operating sound under
any of these conditions.
!Automatic release function by ac-
celerator pedal
The parking brake will be automatically
released by depressing the accelerator
pedal. However, the automatic release
function does not operate under the
following conditions.
.Any door (other than the trunk lid) is
open.
.The driver’s seatbelt is not fastened.
If the parking brake is automatically
released, the electronic parking brake
indicator light and the indicator light on
the parking brake switch turn off.
!Emergency brake
CAUTION
Use the emergency brake only in
case of an emergency. If the emer-
gency brake is excessively used, the
brake parts will wear down faster or
the brake may not work sufficiently
due to brake overheating.
NOTEWhile using the emergency brake:
.The electronic parking brake indica-
tor light and the indicator light on the
parking brake switch illuminate and a
chirp sounds.
.A sound may be heard from the
engine compartment. This is the oper-
ating sound of the brake that is acti-
vated by the Vehicle Dynamics Control
system, and does not indicate a mal-
function.
If the foot brake has a malfunction, you can
stop the vehicle by pulling the parking
brake switch continuously.
While applying the emergency brake, the
electronic parking brake indicator light and
the indicator light on the parking brake
switch illuminate and a chirp sounds.
!Electronic parking brake system
warning
CAUTION
If the brake system warning light
turns on, the electronic parking
brake system may be malfunction-
ing. Immediately stop your vehicle in
the nearest safe location and con-
tact your SUBARU dealer.If a malfunction occurs in the electronic
parking brake system, the brake system
warning light turns on. Refer to“Electronic
parking brake indicator light (models with
electronic parking brake system)”F3-23.
&Parking tipsWhen parking your vehicle, always per-
form the following items.
.Apply the parking brake firmly.
.For MT models, put the shift lever in the
“1”(1st) for upgrade or“R”(Reverse) for a
downgrade.
.For CVT models, put the select lever in
the“P”(Park) position.
Never rely on the mechanical friction of the
transmission alone to hold the vehicle.When parking on a hill, always turn the

.Do not tow a trailer.
.If used for a purpose other than
sealing a flat tire, the flat tire
repair kit may cause a severe
accident or injury due to the fact
that compressed air can act as an
explosive or propellant.
.Safely park your vehicle on the
roadside so that you do not
obstruct the flow of traffic and
so that you are able to seal the flat
tire without being in danger.
.Apply the parking brake, even if
the vehicle is parked on a level
road, to make sure that the vehi-
cle will not move.
.Stop the engine before sealing
the flat tire.
.Turn on the hazard warning
flasher while sealing the flat tire.
.Do not attempt to remove foreign
objects like nails or screws that
have penetrated the tire. Leave
them as they are.
.Never leave the flat tire repair kit
unattended while in use.
.Only one tire can be repaired with
one bottle of sealant.
.The tires can be repaired when
the ambient temperature is228F(308C) or higher.
CAUTION
.Remember that the flat tire repair
kit only provides temporary mo-
bility. Regulations concerning
tire repair after usage of flat tire
repair kit may differ from country
to country. We recommend that
you consult your SUBARU dealer
or tire dealer for advice.
.Store the flat tire repair kit safely
and secure it in the cargo area.
Storing it anywhere in the pas-
senger compartment is not advi-
sable because it could strike an
occupant in the event of a sudden
stop or collision and cause injury.
.Use the flat tire repair kit with
original vehicle tires only.
.Do not keep the air compressor
operating for more than 10 min-
utes, otherwise there is a risk of
overheating.
.The temperature of the air com-
pressor may become high. Be
careful not to burn yourself.
.When raining, take measures to
prevent the air compressor frombeing exposed directly to the
rain. Exposing to rain may cause
a malfunction.
.Do not use air compressors other
than the one in the repair kit.
Using an air compressor other
than the one in the repair kit may
damage the tires.
.Do not disassemble or modify the
air compressor to enable the use
of a power supply or a battery
other than DC12V.
.If a temporary puncture repair is
performed with the repair kit, the
Tire Pressure Monitoring System
(TPMS) may not operate nor-
mally.

Engine overheating
WARNING
Never attempt to remove the radiator
cap until the engine has been shut
off and has fully cooled down. When
the engine is hot, the coolant is
under pressure. Removing the cap
while the engine is still hot could
release a spray of boiling hot cool-
ant, which could burn you very
seriously.
If the engine overheats, safely pull off the
road and stop the vehicle in a safe
location.&If steam is coming from the
engine compartment.Turn off the engine and get everyone
away from the vehicle until it cools down.
.Contact an authorized SUBARU deal-
er.
&If no steam is coming from the
engine compartment1. Keep the engine running at idling
speed.
2. Open the engine hood to ventilate the
engine compartment. Refer to“Engine
hood”F11-9.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact an authorized
SUBARU dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.Temperature gauge
1) Normal operating rangeIf temperature gauge stays in the over-
heated zone, turn off the engine. Refer to
“Temperature gauge”F3-11.4. After the engine has fully cooled down,
check the coolant level in the reserve tank.
If the coolant level is below the“LOW”
mark, add coolant up to the“FULL”mark.
NOTEFor details about how to check the
coolant level or how to add coolant,
refer to“Engine coolant”F11-17.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank. Then
remove the radiator cap and fill the radiator
with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
