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

Vehicle Dynamics Control OFF switchWhen you press the switch briefly or for
more than approximately 2 seconds during
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 first.
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 Dy-
namics Control system and thus delays
utilizing their functions as a reaction to
vehicle behavior in comparison with the
Vehicle Dynamics Control mode. Use this
mode in driving situations where the
vehicle dynamic performance will improve
without decreasing engine torque control.
When you press the switch 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 you press
the switch 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.
When you press the switch for more than
approximately 2 seconds during engine
operation, the Vehicle Dynamics Control
OFF indicator light on the combination
meter illuminates. When you press the
switch again to reactivate the Vehicle
Dynamics Control system, the Vehicle

Creating an adequate driving wheel slip by
deactivating the Vehicle Dynamics Control
system temporarily may help to escape
from the following situations. Use the
Vehicle Dynamics Control OFF mode as
necessary.
.a standing start on a steeply sloping
road with a snowy, gravel-covered, or
otherwise slippery surface
.extrication of the vehicle when its
wheels are stuck in mud or deep snow
You should not deactivate the Vehicle
Dynamics Control system except under
the above-mentioned situations.NOTE.If you turn the ignition switch 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 you press and hold the switch for
30 seconds or longer, the Vehicle
Dynamics 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 system. Do
not deactivate the Vehicle Dynamics
Control system except when absolutely
necessary.
.Even when the Vehicle Dynamics
Control OFF mode is selected, compo-
nents of the brake control system may
still activate. When the brake control
system is activated, the Vehicle Dy-
namics Control operation indicator
light illuminates.
Tire pressure monitoring
system (TPMS) (U.S.-spec.
models)Low tire pressure warning lightThe tire pressure monitoring system pro-
vides the driver with a warning message by
sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 20 mph (32 km/h). Also, this
system may not react immediately to a
sudden drop in tire pressure (for example,
a blow-out caused by running over a sharp
object).
