Starting and operating/Parking your vehicle
Parking your vehicle WARNING. Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to them.
. Do not park the vehicle over
flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
. Be sure to stop the engine if you
take a nap in the vehicle. If
engine exhaust gas enters the
passenger compartment, occu-
pants in the vehicle could die
from carbon monoxide (CO) con-
tained in the exhaust gas. & Parking brake (models with-
out electronic parking brake
system) To set the parking brake, depress the
brake pedal firmly and hold it down until
the parking brake lever is fully pulled up.
To release the parking brake, perform the
following procedure.
1. Pull the lever up slightly.
2. Press the release button.
3. Lower the lever while keeping the
button pressed.
When the parking brake is set while the
engine is running, the parking brake
warning light illuminates. After starting
the vehicle, be sure that the warning light
has turned off before the vehicle is driven.
Refer to “ Parking brake indicator (models without electronic parking brake system) ”
F 3-21.
CAUTIONNever drive while the parking brake
is set because this will cause un-
necessary wear on the brake lin-
ings. Before starting to drive, always
make sure that the parking brake
has been fully released.
& Electronic parking brake
(models with electronic
parking brake system)
1) Parking brake switch
2) Indicator light
3) Release the electronic parking brake

WARNING. Before exiting the vehicle, make
sure that you turn off the engine.
Otherwise, the parking brake
may be released and an accident
may occur.
. If the brake system warning light
turns on, the electronic parking
brake system may be malfunc-
tioning. Immediately stop your
vehicle in a safe location, use
tire stops under the tires to
prevent the vehicle from moving
and contact your SUBARU deal-
er.
. If the electronic parking brake is
operated when the brake is over-
heated or the vehicle is on a
steep slope, the electronic park-
ing brake indicator light may
flash. In this case, the vehicle
may start to move and it may lead
to an accident. Always use the
tire stops.
CAUTION
. When the electronic parking
brake system has a malfunction
and the parking brake cannot be applied, contact your SUBARU
dealer immediately for an inspec-
tion. If you have to park your
vehicle in such conditions, per-
form the following procedure.
– Stop your vehicle in a flat
location.
– Shift the select lever in the “ P ”
position. When the select le-
ver cannot be shifted into the
“ P ” position, you must re-
lease shift lock. Refer to “ Shift
lock function ” F 7-27.
– Use tire stops under the tires
to prevent the vehicle from
moving.
. Never drive while the parking
brake is applied because this will
cause unnecessary wear on the
brake linings. Before starting to
drive, always make sure that the
parking 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 ” F 3-21.
NOTE . If the parking brake switch is
pressed with the ignition switch in the
“ ACC ” or “ LOCK ” / “ OFF ” position, the
parking brake is not released.
. If the parking brake switch is
pressed without depressing the brake
pedal, the parking brake is not re-
leased.
. 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.
. When the electronic parking brake
system has a malfunction or the elec-
tronic parking brake operation is pro-
hibited temporarily, if the parking brake Starting and operating/Parking your vehicle
– CONTINUED –7-45

Starting and operating/Parking your vehicle
switch is operated, a chirp sound is
heard and the electronic parking brake
indicator light flashes.
. 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 the operation of the electronic
parking brake switch is stopped mid-
way or performed extremely slowly, the
system may detect an error and turn on
the brake system warning light. How-
ever, this does not indicate a malfunc-
tion 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 the electronic parking brake
switch is malfunctioning and the elec-
tronic parking brake cannot be re-
leased, refer to the instructions de-
scribed in “ Automatic release function
by accelerator pedal ” F 7-46.
After activating the EPB, you may hear a short sound several minutes after the
electronic parking brake indicator light
illuminates 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.
– 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 electronic parking brake system has
an automatic release function. The park-
ing brake will be automatically released by
depressing the accelerator pedal. How-
ever, 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.
NOTE Even if you have applied the parking
brake, the parking brake will be auto-
matically released when the accelera-
tor pedal is depressed.
! Hill Holder function
The electronic parking brake system has a
Hill Holder function. If the Hill Holder
function is activated, the parking brake
will be automatically applied when stop-
ping on an uphill slope with the brake
pedal depressed. In this case, the electro-
nic parking brake indicator light and the
indicator light on the parking brake switch
illuminate.
The Hill Holder function also operates
while driving uphill in reverse.
NOTE . The Hill Holder function may not
activate on a gentle uphill slope. In this
case, manually apply the electronic
parking brake.
. If you do not depress the brake
pedal sufficiently, the Hill Holder func-
tion may not operate properly. How-
ever, this is not a malfunction. When
stopping on an uphill slope, depress
the brake pedal firmly and release it
after the electronic parking brake in-7-46

dicator light illuminates.
. Depending on the condition of the
road surface and braking force, the
brakes operate temporarily and feel
different than usual.
. When the electronic parking brake
system has a malfunction while the Hill
Holder function is activated, a chirp
sound is heard, the Hill Holder indica-
tor light turns off and the brake system
warning light turns on.
. When the hill holder activates on a
slope, the electronic parking brake is
engaged. The electronic parking brake
will release when you accelerate from
the stop. If you manually release the
electronic parking brake while the hill
holder is activated, the hill holder
function is cancelled and will not re-
engage until the vehicle has moved
some distance. In that case, you will
need to manually engage the electronic
parking brake if needed. ! Hill Holder switch
WARNINGWhen stopping on an uphill slope
with the Hill Holder function acti-
vated, release the brake pedal after
the electronic parking brake indica-
tor light has illuminated. Otherwise,

& Parking tips When 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
steering wheel. When the vehicle is7-48

headed up the hill, the front wheels should
be turned away from the curb.
When facing downhill, the front wheels
should be turned into the curb.
WARNING
. Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to people.
. Do not park the vehicle over
flammable materials such as dry grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
. Be sure to stop the engine if you
take a nap in the vehicle. If
engine exhaust gas enters the
passenger compartment, occu-
pants in the vehicle could die
from carbon monoxide (CO) con-
tained in the exhaust gas.
CAUTIONIf your vehicle has a front under-
spoiler and rear underspoiler (both
optional), pay attention to blocks
and other obstructions on the
ground when parking. The under-
spoilers could be damaged by con-
tact with them. Hill start assist system
(models without electronic
parking brake system) 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 (MT models) and
brake pedal (both MT and CVT
models) 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.Starting and operating/Hill start assist system (models without electronic parking brake system)

Starting and operating/Hill start assist system (models without electronic parking brake system)
1) Starting forward facing uphill
2) Starting backward facing downhill
A) Brake pedal (both MT models and CVT
models)
B) Clutch pedal (MT models only)
In both these cases, the Hill start assist
system operates under the following con- ditions.
. when the clutch pedal is depressed
while the brake pedal is also depressed
(MT models)
. when the vehicle has stopped with the
brake pedal depressed (CVT models)
Braking power is maintained temporarily
(for approximately 2 seconds) by the Hill
start assist system after the brake pedal is
released. The driver is therefore able to
start the vehicle in the same way as on a
level grade, just using the clutch pedal
(MT models only) and accelerator pedal
(all models).
If the braking power of the Hill start assist
system is insufficient after the brake pedal
is released, apply more braking power by
depressing the brake pedal again.
The Hill start assist system may not
operate on slight grades. Also, the Hill
start assist system does not operate in the
following cases.
. when starting backward facing uphill
. when starting forward facing downhill
. while the parking brake is applied
. while the ignition switch is in the “ ACC ”
or “ LOCK ” / “ OFF ” position
. while the Hill start assist warning light/7-50
