functioning. If this happens, however, you
will have to push the pedal much harder
than normal and the braking distance will
increase.
NOTE
Some sound accompanying operation
of the vacuum pump may be heard from the engine compartment during
driving. This does not indicate a fault. „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.
ABS (Anti-lock Brake Sys-
tem)
700040
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. y
The ABS system does not always
decrease stopping distance. You
should always maintain a safe fol-
lowing distance from other vehi-
cles.
y When driving on badly surfaced
roads, gravel roads, icy road, 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, therefore,
reduce your speed and leave am-
ple distance from other vehicles.

– CONTINUED –
The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road surfac-
es. 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). „
ABS system self-check
You may feel a slight shock in the brake
pedal and hear the operating sound ofABS from the engine compartment just af-
ter the vehicle is started. This is caused by
an automatic functional test of the ABS
system being carried out and does not in-
dicate any abnormal condition. „
ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON” posi-
tion and goes out after approximately twoseconds.
This is an indication that the ABS system
is working properly.
NOTE
If the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal. y The warning light comes on right af-
ter the engine is started but goes out
immediately, remaining off. y The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h). y The warning light comes on during
driving, but it goes out immediately
and remains off.
When driving with an insufficient battery
y
When you feel the ABS system
operating, you should maintain
constant brake pedal pressure.
Do not pump the brake pedal
since doing so may defeat the op-
eration of the ABS system.
If the warning light behaves as fol-
lows, the ABS system may not be
working properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues 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).

ing driving.
If these occur, have the ABS system
repaired at the first available oppor-
tunity by your SUBARU dealer.

voltage such as when the engine is jump started, the ABS warning light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out. 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 system and uses some of the ABS
system’s components to perform its func-
tion of optimizing the distribution of brak- ing 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. „
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 simultaneously during driv-
ing.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are ap-
plied 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
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 inspected.
4. If both warning lights come on again
and stay illuminated 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 in-
spected.
6. If the brake fluid level is below the
“MIN” mark, DO NOT drive the vehicle. In-
stead, have the vehicle towed to the near-
est SUBARU dealer for repair.
Vehicle Dynamics Control
system y
Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
yIf 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.
Always use the utmost care in driv-
ing – overconfidence because you
are driving with a Vehicle Dynamics
Control system equipped vehicle
could easily lead to a serious acci-
dent. yEven if your vehicle is equipped
with Vehicle Dynamics Control,
winter tires or snow chains
should be used when driving on
snow-covered or icy roads; in ad-
dition, vehicle speed should be re-
duced considerably. Simply hav-
ing a Vehicle Dynamics Control
system does not guarantee that
the vehicle will be able to avoid
accidents in any situation.

7-20 Starting and operating
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system ad-
justs the engine’s output and the wheels’
respective braking forces to help maintain
traction and directional control. yTraction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
steady illumination of the Vehicle Dynam-
ics Control operation indicator light. y Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’ tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.
NOTE y Slight twitching of the brake pedal may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or steering wheel shak-
ing may also be noticed in this situa-
tion. These are normal characteristics
of Vehicle Dynamics Control operation
and are no cause for alarm. y
When driving off immediately after
starting the engine, a short-lived oper-
ation noise may be noticed coming
from the engine compartment. This
noise is generated as a result of a
check being performed on the Vehicle
Dynamics Control system and is nor- mal. y Depending on the timing of activa-
tion of the brakes, certain situations
may occur just after driving off where
the brake pedal seems to exhibit a jolt-
ing motion. This too is a consequence
of the Vehicle Dynamics Control opera-
tional check and is normal. y In the circumstances listed in the fol-
lowing, the vehicle may be more unsta-
ble than it feels to the driver. The Vehi-
cle Dynamics Control System may
therefore operate. Such operation does
not indicate a system fault.

y
Activation of the Vehicle Dynam-
ics Control system is an indica-
tion that the road being travelled
on has a slippery surface; since
having Vehicle Dynamics Control
is no guarantee that full vehicle
control will be maintained at all
times and under all conditions, its
activation should be seen as a
sign that the speed of the vehicle
should be reduced considerably.
y Whenever suspension compo-
nents, steering components, or an
axle are removed from a vehicle
equipped with Vehicle Dynamics
Control, have an authorized
SUBARU dealer perform an in-
spection of that system.
y The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Control
system is operating properly:
– All four wheels should be fitted
with tires of the same size, type,
and brand. Furthermore, the
amount of wear should be the
same for all four tires.
– Keep the tire pressure at theproper level as shown on the
vehicle placard attached to the
driver’s side door pillar.
