Pull the switch rearward to reduce the
initial LSD torque. When the lowest posi-
tion of the driver’s control center differen-
tial indicator is displayed, the initial LSD
torque will be minimum.
CAUTION
.Do not operate the control switch
when a wheel slippage occurs.
Wait until the wheelspin has been
brought under control.
.Under any of the following condi-
tions after setting to the manual
mode, pull the center differential
control switch to minimize the
initial LSD torque:
–When a temporary spare tire is
installed–When your vehicle is towed
–When the vehicle is stopped
with the manual mode se-
lected
NOTE.A higher initial LSD torque setting
gives the vehicle greater traction when
driving straight ahead but makes cor-
nering more difficult. Remember this
when adjusting the initial LSD torque.
In general, higher initial LSD torque
settings assist driving on slippery
roads and lower settings for non-slip-
pery roads. When the vehicle is stuck in
snow or mud, setting the initial LSD
torque to the maximum will help to free
the vehicle.
.The setting of the initial LSD torque
will remain even when the auto mode is
selected or the ignition switch is turned
to the“LOCK”/“OFF”position. How-
ever, the initial LSD torque will be
minimized when the battery is discon-
nected and reconnected.
.During cornering or when making
turns (especially when going into the
garage), the rotational difference be-
tween the front and rear wheels may
cause a braking effect accompanied by
vibration and noise. This does notindicate a problem. The phenomenon
will disappear when setting the initial
LSD torque to the minimum.
In the auto mode, it controls the initial
LSD torque automatically. While in the
auto mode, this phenomenon some-
times occurs depending on the driving
condition, however, it does not indicate
a problem.
.Use the center differential indicator
only as a rough indication of the initial
LSD torque.
.If you operate the center differential
control switch while quickly accelerat-
ing or turning a tight corner, you may
feel slight shocks. This is due to
differential action by the center differ-
ential and does not indicate a problem.
&Temporary releaseWhen the driver stops the vehicle and pulls
the parking brake lever after manually
setting the initial LSD torque, the LSD
torque is temporarily minimized. However
the indicator on the combination meter
continues to show the driver’s selected
initial LSD torque. When the driver re-
leases the parking brake lever, the initial
LSD torque set by the driver is restored.

efficiency and smooth driveability without
stress. Power delivery is moderate during
acceleration for maximum fuel efficiency.
This is ideal for around-town driving and
situations that do not require full power
output. It provides better control in difficult
driving conditions, such as slippery roads
or loose surfaces, due to gentler throttle
response.
STI:When the Intelligent (I) mode is selected, a
shift-up indicator“
”on the combination
meter will blink to signal the best time to
shift gears for maximum fuel efficiency.
Except STI:
The linear acceleration characteristic of
the Intelligent (I) mode is ideal for normal
driving.
&Sport (S) mode!For all-around performance drivingThe Sport (S) mode provides the engine
power desired by those who want to make
the driving experience their own personal
adventure.
STI:
The linear acceleration characteristic of
the Sport (S) mode is ideal for normal
driving.
&Sport Sharp (S#) mode!For maximum performance drivingFor sports-minded drivers, the Sport
Sharp (S#) mode offers an exhilarating
level of engine performance and control.
The throttle becomes more responsive
regardless of the engine speed. Delivering
maximum driving enjoyment, this mode is
ideal for driving on twisting roads and for
merging or overtaking other vehicles on
the freeway with confidence.

Electronic Brake Force Dis-
tribution (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
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
malfunctionsBrake and ABS warning lightIf 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
while 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.
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”F11-24.
.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 prop-
erly. If the light remains illumi-
nated, have the brakes inspected
by a SUBARU dealer immedi-
ately.
.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.
Vehicle Dynamics Control
system
WARNING
Always use the utmost care in driv-
ing–overconfidence because you
are driving a vehicle with the Vehicle
Dynamics Control system could ea-
sily lead to a serious accident.
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-
namics Control is no guaranteethat 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.
.Observe the following precau-
tions in order to ensure that the
Vehicle Dynamics Control sys-
tem is operating properly:
–Fit all four wheels 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 the
proper level as shown on the
vehicle placard attached to
the driver’s side door pillar.
–Use only the specified tempor-
ary spare tire to replace a flat
tire. With a temporary spare
tire, the effectiveness of the
Vehicle Dynamics Control
system is reduced and this
