5. Push down on the screwdriver and move the selec-
tor lever from the “P” to the “N” position.
6. Remove the screwdriver from the hole. Depress
the brake pedal and start the engine.
Take your vehicle to the nearest SUBARU dealer im-
mediately to have the system repaired.
Limited slip differential (LSD) (if
equipped)
The LSD provides optimum distribution of power ac-
cording to the difference in revolutions between the
right and left wheels that may be caused by certain
driving conditions, thereby improving driving stability
on snow-covered, muddy or other slippery roads or
when high speed driving.
NOTE (WRX-STi)
The rear differential may emit a knocking sound
when the vehicle is driven slowly with the steering wheel turned fully to either side. This sound oc-
curs because of the design of the mechanical LSD.
It does not indicate a problem.
y
Never start the engine while a tire on one side
is jacked up, as the vehicle may move. y If one tire is spinning in mud, avoid continued
spinning at high speed as this could adversely
affect the LSD. y If you use a temporary spare tire to replace a
flat tire, be sure to use the original temporary
spare tire stored in the vehicle. Using other siz-

es will adversely affect the LSD.Power steering
The power steering system operates only when the
engine is running.
If you lose power steering assist because the engine
stops or the system fails to function, you can steer but
it will take much more effort.
NOTE
Right after the engine has been started and before
it has warmed up, you may hear a noise coming
from areas adjacent to the power steering pump
which is located at the right-front area of the en-
gine compartment. This noise is normal. It does
not indicate power steering system trouble.
Do not hold the steering wheel at the fully
locked position left or right for more than five
seconds. This may damage the power steering
pump.

Braking „
Braking tips
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.
T When the brakes get wet
When driving in rain or after washing the vehicle, the
brakes may get wet. As a result, brake stopping dis-
tance will be longer. To dry the brakes, drive the vehi-
cle at a safe speed while lightly depressing the brake
pedal to heat up the brakes. T 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 im-
properly because of brake fluid overheating, caused
by overheated brake pads. To help prevent this, shift
into a lower gear to get stronger engine braking. T
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
T 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 vehi- cle. T 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, re-
sulting 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 push the pedal much harder

than normal and the braking distance will increase. „Disc brake pad wear warning indica- tors
The disc brake pad wear warning indicators 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, immediately have your vehicle
checked by your SUBARU dealer.ABS (Anti-lock Brake System)
The ABS system prevents the lock-up of wheels which
may occur during sudden braking or braking on slip-
pery road surfaces. This helps prevent the loss of
steering control and directional stability caused by
wheel lock-up.
When the ABS system 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 system will not operate when the vehicle
speed is below approximately 6 mph (10 km/h).
Always use the utmost care in driving – over-
confidence because you are driving with an
ABS equipped vehicle could easily lead to a se-
rious accident.
y The ABS system does not always decrease
stopping distance. You should always maintain
a safe following distance from other vehicles.

Starting and operating
y
When driving on badly surfaced roads, gravel
roads, icy roads, or over deep newly fallen
snow, stopping distances may be longer for a
vehicle with the ABS system than one without.
When driving under these conditions, there-
fore, reduce your speed and leave ample dis-
tance from other vehicles. y When you feel the ABS system operating,
you should maintain constant brake pedal pres-
sure. Do not pump the brake pedal since doing
so may defeat the operation of the ABS system.
„ ABS system self-check
You may feel a slight shock in the brake pedal and
hear the operating sound of ABS from the engine com-
partment just after the vehicle is started. This is
caused by an automatic functional test of the ABS sys-
tem being carried out and does not indicate any abnor-
mal condition. „
ABS warning light
The ABS warning light comes on when the ignition
switch is turned to the “ON” position and goes out after
about two seconds.
This is an indication that the ABS system is working
properly.
When driving with an insufficient battery voltage such
as when the engine is jump started, the ABS warning
light may come on. This is due to the low battery volt-
age and does not indicate a malfunction. When the
battery becomes fully charged, the light will go out.

If the warning light behaves as follows, the ABS
system may not be working properly.
When the warning light is on, the ABS function
shuts down; however, the conventional brake
system continues to operate normally. yThe warning light does not come on when the
ignition switch is turned to the “ON” position. y The warning light comes on when the ignition
switch is turned to the “ON” position, but it
does not go out even when the vehicle speed
exceeds approximately 8 mph (12 km/h). y The warning light comes on during driving.
If these occur, have the ABS system repaired at
the first available opportunity by your SUBARU
dealer.
NOTE
If the warning light behavior is as described be-
low, the ABS system may be considered normal. y The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off. y The warning light remains on after the engine
has been started, but it goes out when the vehicle speed reaches about 8 mph (12 km/h).y
The warning light comes on during driving, but
it goes out immediately and remains off.

Electronic Brake Force Distribution
(EBD) system
The EBD system maximizes the effectiveness of the
brakes by allowing the rear brakes to supply a greater
proportion of the braking force. It functions by adjust-
ing 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 system
and uses some of the ABS system’s components 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 malfunc- tion.

Steps to take if EBD system fails
If a malfunction occurs in the EBD system, the system
stops working and the brake system warning light and
ABS warning light come on simultaneously.
The EBD system may be faulty if the brake system
warning light and ABS warning light illuminate simulta-
neously during driving.
Even if the EBD system fails, the conventional braking
system will still function. However, the rear wheels will
be more prone to locking when the brakes are applied
harder than usual and the vehicle’s motion may there-
fore 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 place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both warning lights go
out, the EBD system may be faulty. Drive carefully to
the nearest SUBARU dealer and have the system in-
spected.
4. If both warning lights come on again and stay illu-
minated after the engine has been restarted, shut
down the engine again, apply the parking brake, and
check the brake fluid level.
5. If the brake fluid level is not below the “MIN” mark,
the EBD system may be faulty. Drive carefully to the
nearest SUBARU dealer and have the system inspect-
ed.
6. If the brake fluid level is below the “MIN” mark, DO
NOT drive the vehicle. Instead, have the vehicle towed
to the nearest SUBARU dealer for repair.
yDriving with the brake system warning light
on is dangerous. This indicates your brake sys-
tem may not be working properly. If the light re-
mains on, have the brakes inspected by a
SUBARU dealer immediately. y If at all in doubt about whether the brakes are operating properly, do not drive the vehicle.
Have your vehicle towed to the nearest
SUBARU dealer for repair.

Parking your vehicle „
Parking brake
To set the parking brake, press the brake pedal firmly
and hold it down while fully pulling up the parking
brake lever.
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 run-
ning, the parking brake warning light comes on. After
starting the vehicle, be sure that the warning light has
gone out before the vehicle is driven. Refer to the “Warning and indicator lights” section (chapter 3).
Never drive while the parking brake is set be-
cause this will cause unnecessary wear on the
brake linings. Before starting to drive, always
make sure that the parking brake has been fully
released.
„ Parking tips
When parking your vehicle, always set the parking brake firmly and put the shift lever in the “1” (1st) for an
upgrade or “R” (Reverse) for a downgrade for manual
transmission vehicles, or in the “P” (Park) position for
automatic transmission vehicles. Always set the park-
ing brake firmly when parking your vehicle. Never rely
on 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.
y
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. y Do not park the vehicle over flammable mate-
rials such as dry grass, waste paper or rags, as
