switch is turned 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
When 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.
NOTE
If the steering wheel is operated 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.
. The steering wheel is operated fre-
quently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently turn-
ing the steering wheel during parallel parking.
.
The steering wheel remains 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 steering
wheel 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 fre-
quently, this may result in a malfunc-
tion 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 cause
Starting and operating/Braking

Starting and operating/Braking
a loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe location.
&Brake system
! Two separate circuits
Your vehicle has two separate circuit
brake systems. Each circuit works diag-
onally 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. !
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 bring 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.
NOTE
When 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 an ABS operating
noise from the engine compartment.
& Disc brake pad wear warning
indicators
The disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, im-
mediately have your vehicle checked by
your SUBARU dealer.
7-36

ABS (Anti-lock Brake Sys-
tem)
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).
WARNING
Alwaysusetheutmostcarein
driving–overconfidence because
you are driving a vehicle with the
ABS could easily lead to a serious
accident.
CAUTION
. The ABS does not always de-
crease stopping distance. You
should always maintain a safe following distance from other
vehicles.
. When driving on badly surfaced
roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS than
one without. When driving under
these conditions, therefore, re-
duce your speed and leave ample
distance from other vehicles.
. When tire chains are installed,
stopping distances may be long-
er for a vehicle with the ABS than
one without. Be sure to reduce
your speed and maintain a safe
distance from the vehicle in front.
. When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do not
pump the brake pedal since
doing so may defeat the opera-
tion of the ABS.
& ABS self-check
Just after the vehicle is started, you may
feel on the brake pedal a vibration similar
to when the ABS operates, and you may
also hear the sound of the ABS working
from the engine compartment. This is caused by an automatic functional test of
the ABS being carried out and does not
indicate a malfunction.

Starting and operating/ABS (Anti –lock Brake System)7-37

Starting and operating/Electronic Brake Force Distribution (EBD) system
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
system malfunction, 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
Brake and ABS warning light (type A)
Brake and ABS warning light (type B)
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 malfunctions, the
conventional braking system will still func-
tion. However, the rear wheels will be
more prone to locking when the brakes
are applied harder than usual and the
vehicle
’s motion may therefore become
somewhat harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps.
1. Stop the vehicle in the nearest safe,
flat location.
2. Apply the parking brake and turn off
the engine.
3. Restart the engine.
4. Release the parking brake.
Even if both warning lights turn off:
The EBD system may be malfunctioning.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
If both warning lights illuminate again
and remain illuminated after restarting
the engine:
1. Turn off the engine again.

Starting and operating/Parking your vehicle
21.
CAUTION
Never 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.
&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 is
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.
CAUTION
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), pay attention to blocks

Starting and operating/Hill start assist system
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/ Hill start assist OFF indicator light is
illuminated
When using the Hill start assist system, a
braking effect may be felt even after the
brake pedal has been released. However,
this braking effect should disappear once
the clutch pedal is released.
CAUTION
The braking power of the Hill start
assist system may not be sufficient
when strong braking power is
needed (e.g., when towing a trailer).
NOTE
A slight jolt may be felt when the
vehicle begins to move forward after
being reversed.
&
To activate/deactivate the Hill
start assist system
CAUTION
While the Hill start assist system is
deactivated, when starting on an
uphill grade, braking power is not
maintained if the brake pedal is
released. Start on an uphill grade
by using the parking brake.

&To temporarily cancel the
cruise control
The cruise control can be temporarily
canceled in the following ways.
. Press the “CANCEL”button.
. Press the X-mode switch to activate
the X-mode (models with X-mode).
. Depress the brake pedal.
. Depress the clutch pedal (MT models
only).
WARNING
For CVT models, you can cancel the
cruise control by shifting the select
lever into the “N ” position. However,
do not shift the lever into the “N ”
position while driving except in case
of emergency. If the select lever is shifted into the
“N ” position, the
engine brake will no longer work.
This could result in an accident.
The cruise control set indicator light in the
combination meter turns off when the
cruise control is canceled.
To resume the cruise control after it has
been temporarily canceled and with vehi-
cle speed of approximately 20 mph (30
km/h) or more, press the “RES/SET ”
switch to the “RES ”side to return to the
original cruising speed automatically.
The cruise control set indicator light in the
combination meter will automatically illu-
minate at this time.
& To turn off the cruise control
There are two ways to turn off the cruise
control:
. Press the cruise control main button
again.
. Turn the ignition switch to the “ACC”or
“ LOCK ”/“OFF ”position (but only when the
vehicle is completely stopped).
& To change the cruising speed
! To increase the speed (by the “RES/
SET ”switch)
Press the “RES/SET ”switch to the “RES”
side and hold it until the vehicle reaches
the desired speed. Then, release the
switch. The vehicle speed at that moment
will be memorized and treated as the new
set speed.
