Active Sound Control
242NOTEIn the following situations, the driving
mode will automatically change to nor-
mal mode:
 When the engine is turned off after
driving in Sport mode or Snow mode.
 When adaptive cruise control/cruise
control is activated while driving in
Sport mode.
 If a malfunction occurs in the engine
or automatic transmission electrical
control system while Sport mode or
Snow mode is selected.
 When in Sport mode and the idling
speed is high during warm-up or when
the road surface is slippery and stop-
ping/starting off is automatically
performed in second gear.
7-8. Active Sound ControlThe active sound control provides
dynamic engine sounds. When driving
with Sport mode selected, the engine
sounds will be particularly loud.NOTEThe operational/non-operational set-
ting of the Active Sound Control can
be changed by a SUBARU dealer. Con-
tact your SUBARU dealer for details.
When the driving mode is changed,
the sound of the active sound control
will be stopped for approximately 1
second, this is not a malfunction.
7-9. Power SteeringPower steering warning lightThe vehicle is equipped with an electric
power steering system. When the ignition
switch is turned to the “ON” position, the
power steering warning light on the combi-
nation meter illuminates to inform the
driver that the warn ing system is func-
tioning properly. Then, if the engine
started, the warni ng light turns off to
inform the driver that the steering power
assist is operational.

Braking
244▼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 vacuum pump
system to assist brakin g 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.
▼ Supplemental booster function
when vacuum pressure fails
While the ignition switch is turned “ON”
and the engine is running, the supple-
mental booster function operates when
the brake booster performance is
decreased due to insufficient vacuum
boost.
When the brake pedal is depressed while
the supplemental booster function is oper-
ating, an operation sound and brake pedal
vibration may be generated. This is not a
malfunction.
▼ Brake assist system
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-
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.
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.

Vehicle Stability Control (VSC)/TRAC System
249
Starting and Operating7
– CONTINUED –
▼Disabling the TRAC System
If the vehicle gets stuck in mud, dirt or
snow, the TRAC system may reduce
power from the engine to the wheels.
Pressing the Vehicle Stability Control
(VSC) OFF switch to turn the system off
may make it easier for you to rock the
vehicle in order to free it. In this case, the
brake LSD function remains on. To turn
the TRAC system off, quickly press and
release the button. The TRAC OFF indi-
cator light will come on. Press the button
again to turn the system back on.
Creating adequate driving wheel slip by
deactivating the TRAC system may help
to recover from the loss of traction. Use
the Vehicle Stability Control (VSC) 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 ▼
Turning Off both Vehicle Stability
Control (VSC) and TRAC Systems
To turn the Vehicle Stability Control (VSC)
systems and TRAC system off, press and
hold the Vehicle Stability Control (VSC)
OFF switch for more than 3 seconds while
the vehicle is stopped. The TRAC OFF
indicator light and the Vehicle Stability
Control (VSC) OFF indicator light will
come on. However, on vehicles with an
automatic transmissi on, the brake LSD
function will remain on. Press the button
again to turn the systems back on. With
the Vehicle Stability Control (VSC) system
and TRAC system deactivated, traction
and stability enhancement offered by
Vehicle Stability Control (VSC) system
and TRAC system is unavailable. There-
fore you should not deactivate the Vehicle Stability Control (VSC) system and TRAC

system except under above-mentioned
situations.
NOTE When the switch has been pressed
to deactivate the Vehicle Stability
Control (VSC) system and TRAC
system, the Vehicle Stability Control
(VSC) system and TRAC system auto-
matically reactivates itself the next
time the ignition swit ch is turned to the
“OFF” position and the engine is
restarted.
 If the switch is held down for 30
seconds or longer, the indicator light
turns off, the Vehicle Stability Control
(VSC) 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
“OFF” position and restart the engine.
 When the switch is pressed to deac-
tivate the Vehicle Stability Control
(VSC) system and TRAC system, the
vehicle’s running performance is
comparable with that of a vehicle that
does not have a Vehicle Stability
Control (VSC) system and TRAC
system. Do not deac tivate the Vehicle
Stability Control (VSC) system and
TRAC system except when absolutely
necessary.

toring System (TPMS) (If Equipped)Low tire pressure warning lightThe tire pressure monitoring system
provides the driver with a warning
message by sending a signal from a
sensor that is installed in each wheel
when tire pressure is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 25 mph (40 km/h). Also,
this system may not react immediately to
a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).

7-19. Rear View CameraA rear view camera is attached to the
trunk lid. When the ignition switch is in the
“ON” position and the shift lever (MT
models) or select lever (AT models) is set
to “R”, the rear view camera automatically
displays the rear view image behind the
vehicle on the center information display.
WARNING
 Since the rear view camera uses a
wide-angle lens, the image on the
monitor is diffe rent from the
actual view in terms of distance.
702799
 Since the range of the image on
the monitor is limited, always
check the rear view and the
surrounding area with your eyes
and mirrors, and move backward
at a slow speed. Moving back-
ward only by checking the rear
view image from the camera
could cause an accident. Do not disassemble or modify the
camera, switch or wiring. If
smoke comes out or you smell a
strange odor, stop using the rear
view camera immediately.
Contact your SUBARU dealer for
an inspection. Continued use
may result in accident, fire or
electric shock.
CAUTION
 When washing your vehicle with
a high-pressure washer, do not
allow water to touch the camera
directly. Entry of water in the
camera lens may result in
condensation, malfunction, fire
or electric shock. Since the camera is a precision
device, do not subject it to strong
impacts. Otherwise, malfunction,
fire or electric shock may occur.
