Starting and operating/ABS (Anti – lock Brake System)
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. 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
Always use the utmost care in
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 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 system.
& 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 any abnormal condition.7-36

& ABS warning light Refer to “ ABS warning light ” F 3-20.
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
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.Starting and operating/Electronic Brake Force Distribution (EBD) system

Starting and operating/Vehicle Dynamics Control system
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.
2. Apply the parking brake.
3. Check the brake fluid level. For details
about checking the brake fluid level, refer
to “ Checking the fluid level ” F 11-25.
. If the brake fluid level is not below the
“ MIN ” mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
. 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.
WARNING. Driving with the brake system
warning light illuminated is dan-
gerous. This indicates your brake
system may not be working
properly. If the light remains
illuminated, have the brakes in-
spected by a SUBARU dealer
immediately.
. If at all in doubt about whether
the brakes are operating prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re-
pair. Vehicle Dynamics Control
system WARNINGAlways use the utmost care in
driving – overconfidence because
you are driving a vehicle with the
Vehicle Dynamics Control system
could easily lead to a serious acci-
dent.
CAUTION. Even if your vehicle is equipped
with Vehicle Dynamics Control
system, winter tires should be
used when driving on snow-cov-
ered or icy roads; in addition,
vehicle speed should be reduced
considerably. Simply having a
Vehicle Dynamics Control sys-
tem does not guarantee that the
vehicle will be able to avoid
accidents in any situation.
. Activation of the Vehicle Dy-
namics Control system is an
indication that the road being
travelled on has a slippery sur-
face; since having Vehicle Dy-7-38

namics 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.
. Whenever suspension compo-
nents, steering components, or
an axle are removed from a
vehicle, have an inspection of
that system performed by an
authorized SUBARU dealer.
. The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Con-
trol system is operating properly:
– All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, the amount of wear
should be the same for all
four tires.
– Keep the tire pressure at the
proper level as shown on the
vehicle placard attached to
the driver ’ s side door pillar.
– Use only the specified tem-
porary spare tire to replace a
flat tire. With a temporary
spare tire, the effectiveness of the Vehicle Dynamics Con-
trol system is reduced and
this should be taken into ac-
count when driving the vehi-
cle in such a condition.
. If non-matching tires are used,
the Vehicle Dynamics Control
system may not operate cor-
rectly.
. The Vehicle Dynamics Control
system helps prevent unstable
vehicle motion such as skidding
using control of the brakes and
engine power. Do not turn off the
Vehicle Dynamics Control sys-
tem unless it is absolutely ne-
cessary. If you must turn off the
Vehicle Dynamics Control sys-
tem, drive very carefully accord-
ing to the road surface condition.
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
adjusts the engine ’ s output and the
wheels ’ respective braking forces to help
maintain traction and directional control.
. Traction 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
flashing the Vehicle Dynamics Control
operation indicator light.
. 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.

Vehicle Dynamics Control OFF switch
When the switch is pressed briefly or for
more than approximately 2 seconds dur-
ing engine operation, the mode of the
Vehicle Dynamics Control system will be
changed.
! Vehicle Dynamics Control mode
When the ignition switch is on, this mode
is selected.
This mode enables all controls for ABS,
the Traction Control System, and the
Vehicle Dynamics Control system. Select
this mode for most driving situations.
When this mode is selected, both indicator
lights on the combination meter turn off. ! Traction mode
This mode restricts the functions of the
Traction Control System and Vehicle
Dynamics Control system and thus delays
utilizing their functions as a reaction to
vehicle behavior in comparison with the
Vehicle Dynamics Control mode. This
mode should be used in driving situations
where the vehicle dynamic performance
will improve without decreasing engine
torque control.
When the switch is pressed briefly during
engine operation, the traction mode in-
dicator light and the Vehicle Dynamics
Control OFF indicator light on the combi-
nation meter illuminate. When the switch
is pressed again to reactivate the Vehicle
Dynamics Control system, the traction
mode indicator light and the Vehicle
Dynamics Control OFF indicator light turn
off.
! Vehicle Dynamics Control OFF
mode
This mode allows only the ABS control.
This mode should be used in an emer-
gency situation such as getting out of
snow or mud.
When the switch is pressed for more than
approximately 2 seconds during engine
operation, the Vehicle Dynamics Control
OFF indicator light on the combination meter illuminates. When the switch is
pressed again to reactivate the Vehicle
Dynamics Control system, the Vehicle
Dynamics Control OFF indicator light
turns off.
NOTE . If the ignition switch is turned to the
“ LOCK ” / “ OFF ” position with the Vehi-
cle Dynamics Control system deacti-
vated, the system will be automatically
reactivated the next time the engine is
started.
. If the switch is held down for 30
seconds or longer, the Vehicle Dy-
namics Control OFF indicator light
turns off, the Vehicle Dynamics Control
system is activated, and the system
ignores any further pressing of the
switch. To make the switch usable
again, turn the ignition switch to the
“ LOCK ” / “ OFF ” position and restart the
engine.
. When the Vehicle Dynamics Control
OFF mode is selected, the vehicle ’ s
running performance is comparable
with that of a vehicle that does not
have a Vehicle Dynamics Control sys-
tem. Do not deactivate the Vehicle
Dynamics Control system except when
absolutely necessary.

Driving tips/Winter driving
or ice buildup on the suspension,
disc brakes and brake hoses
underneath the vehicle. If there
is caked snow or ice, remove it,
being careful not to damage the
disc brakes and brake hoses and
ABS harness.
When parking for long periods in cold
weather, you should observe the following
tips.
1. For MT models, place the shift lever in
the “ 1 ” or “ R ” position. For CVT models,
place the select lever in the “ P ” position.
2. Use tire stops under the tires to
prevent the vehicle from moving.
! Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an
antifreeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used
for an extended period, it is best to have
the fuel tank filled to capacity. & Driving on snowy and icy
roads To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle ’ s braking perfor-
mance on snowy and icy roads. For
information on braking on slippery sur-
faces, refer to “ ABS (Anti-lock Brake
System) ” F 7-36 and “ Vehicle Dynamics
Control system ” F 7-38.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control. CAUTIONAvoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’ s intake system and may
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the wiper blades are frozen to the
windshield, use the defroster and the
temperature set for maximum warmth until
the wiper blades are completely thawed.
Refer to “ Climate control ” F 4-1.
If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blades. Refer to “ Defog-
ger and deicer ” F 3-112.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
and the temperature set for maximum
warmth. After the windshield gets warmed
enough to melt the frozen snow on it,
wash it away using the windshield washer.
Refer to “ Windshield washer ” F 3-103.8-8
