Braking
2447-10. Braking■
Braking Tips
▼
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
descending a grade, if only the foot brake
is used, the brakes may start working
improperly because of brake fluid over-
heating, 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
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 fa il, 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 braki ng 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
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.
WARNING
Do not be overco nfident 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.

ABS (Anti-Lock Brake System)
245
Starting and Operating7
– CONTINUED –
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.
■
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, imme-
diately have your vehicle inspected by the
nearest SUBARU dealer.
7-11. ABS (Anti-Lock Brake System)
CAUTION
When you need to brake suddenly,
continue depressing the brake
pedal strongly to bring the effect of
the brake assist.
700040
WARNING
Always use the utmost care in driv-
ing – overconfidence because you
are driving with an ABS equipped
vehicle could easily lead to a seri-
ous accident.
CAUTION
 The ABS does not always
decrease stopping distance. You
should always maintain a safe
following distance from other
vehicles.When driving on badly surfaced
roads, gravel roads, icy road, or
over newly fallen snow, stopping
distances may be longer for a
vehicle with the ABS than one
without. When driving under
these conditions, therefore,
reduce your speed and leave
ample distance from other vehi-
cles.

Electronic Brake Force Distribution (EBD) System
246The 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.■
ABS Self-Check
You may feel a slight shock in the brake
pedal and hear the operating noise of the
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
being carried out and does not indicate
any abnormal condition.■
ABS Warning Light
Refer to "ABS Warning Light" P140.
7-12. Electronic Brake Force Distribution (EBD) SystemThe 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
function fails, 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.
■
EBD System Malfunctions
If a malfunction occurs in the EBD system,
the system stops working and the
following warning lights illuminate simulta-
neously.
 Brake system warning light
 ABS warning light
 Vehicle Stability Control (VSC)
warning light
If the both warning light remains on even
though the parking brake is released, the
brake fluid level may be low or there could
be a problem with the EBD system. Park
the vehicle in a safe place immediately
and contact an SUBARU dealer.
 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 operation of the
ABS.

Parking Brake
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, pull the
lever up slightly, press the release button,
then 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 "Brake System Warning Light"

P140.
■
Parking Tips
When parking your vehicle, always
perform 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 AT models, put the select lever in
the “P” (Park) position.
Never rely on the mechanical friction of
the transmission alone to hold the vehicle.
WARNING
 Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent oper-
ation of the vehicle. Also, on hot
or sunny days, the temperature in
a closed vehicle could quickly
become high enough to cause
severe or possibly fatal injuries to
people.Do not park the vehicle over flam-
mable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust
system parts.Be sure to stop the engine if you
take a nap in the vehicle. If engine
exhaust gas enters the passenger
compartment, occupants in the
vehicle could die from carbon
monoxide (CO) contained in the
exhaust gas.
CAUTION
Never drive while the parking
brake is set because this will
cause unnecessary wear on the
brake linings. Before starting to
drive, always make sure that the
parking brake has been fully
released.
702782
The braking power of the parking
brake may not be sufficient when
stronger braking power is needed
(e.g., when parking on a steep
slope while towing a trailer).

Hill Start Assist System
258In both these cases, the Hill start assist
system operates under the following
conditions.
 The clutch pedal is depressed while the
brake pedal is also depressed (MT
models).
 The vehicle has stopped with the brake
pedal depressed (AT 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 “OFF” position 
While the Hill start assist indicator light
is illuminated. Refer to "Hill Start Assist
Indicator Light" P150.
When using the Hill start assist system, a
braking effect may be felt even after the
brake pedal has been released. However,
for MT models, this braking effect should
disappear once the clutch pedal is
released.
NOTEA slight jolt may be felt when the vehi-
cle begins to move forward after being
reversed.
701109
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).
