Electronic Brake Force Distribution (EBD) System
2467-12. Electronic Brake Force Distribution (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 in tegral 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
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.
■ EBD System MalfunctionsIf a malfunction occurs in the EBD system,
the system stops working and the
following warning lights illuminate simulta-
neously.
 Brake system warning light
 ABS warning light
 Vehicle Stability Control (VSC)
warning light
If all the warning lights remain on even
though the parking brake is released, the
brake fluid level may be low or there could
be a problem with the EBD system. Park
the vehicle in a safe place immediately
and contact an SUBARU dealer.

WARNING
 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. 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.

Reverse Automatic Braking (RAB) System (If Equipped)
277
Starting and Operating7
– CONTINUED –
7-21. Reverse Automatic
Braking (RAB) System (If Equipped)Reverse Automatic Braking (RAB) is a
system designed to help avoid collisions
or reduce collision damage when
reversing the vehicle. If a wall or an
obstacle is detected in the reversing direc-
tion, the system will notify the driver with a
warning sound and may activate the
vehicle’s brakes automatically.
NOTEThe Reverse Automatic Braking (RAB)
system records and stores the follow-
ing data when automatic braking oper-
ates. It does not record conversations,
personal information or other audio
data.
 Distance from the object
 Vehicle speed
 Accelerator pedal operation status
 Brake pedal operation status
 Select lever position
 Outside temperature
 The sensitivity setting of the sonar
sensors
SUBARU and third parties contracted
by SUBARU may acquire and use the
recorded data for the purpose of vehi-
cle research and development.
SUBARU and third parties contracted
by SUBARU will not disclose or pro-
vide the acquired data to any other
third party except under the following
conditions.
 The vehicle owner has given his/her
consent.
 The disclosure/provision is based
on a court order or other legally
enforceable request.
 Data that has been modified so that
the user and vehicle cannot be identi-
fied is provided to a research institu-
WARNING
 Reverse Automatic Braking
(RAB) is not a system intended to
replace the driver’s responsibility
to check their surroundings for
vehicles or obstacles to avoid a
collision. The driver is responsible for
driving safely. Before reversing,
be sure to first depress the brake
pedal and visually check the
surroundings.
 There are some cases in which
the vehicle cannot avoid colli-
sion, because the system opera-
tion has limitations. The warning
sound or automatic braking may
be delayed or may not operate at
all even when an obstacle is
present. Make sure to set the Automatic
Braking to OFF when the vehicle
is on the free roller or on the
chassis dynamometer. Other-
wise, the vehicle may move and it
may cause an accident. Make sure to set the Automatic
Braking to OFF when towing the
vehicle. Otherwis e, the vehicle
may move and it may cause an
accident. The system is not designed to
detect people (including chil-
dren), animals or other moving
objects. Depending on the vehicle condi-
tion or the surrounding environ-
ment, the sonar sensor’s ability
to detect objects may become
unstable.

- The rear bumper is exposed to
strong impact, or the rear bumper is
deformed.
 On a steep hill, the system’s auto-
matic braking ability will be reduced.
 The system is designed to avoid
collisions by automatic hard braking
when the vehicle’s reversing speed is
less than approximately 3 mph (5 km/
h). However, the system does not guar-
antee that the vehicle will be able to
avoid collisions in any situation.
 If the vehicle is reversed at an
extremely slow speed, the driver’s
operation may be prioritized. In this
case, automatic braking will not
operate.
 The system may not be able to
detect and apply the brake with the
following objects. - Sharp or thin objects such as
poles, fences and ropes which may
not reflect the s ound wave emitted
from the sonar sensor.
- Objects that are too close to the
rear bumper when the select lever is
set to the “R” position.
- Objects with a surface which
may not reflect the sound wave
emitted from the sonar sensor such
as a chain link fence.
 Objects the system is not designed
to detect and apply brake. -Pedestrians.
- Moving objects including

moving vehicles.
- Objects which absorbs sound
waves such as cloth or snow.
- Objects whose surface has a
diagonal angle.
- Objects that are low to the
ground such as parking blocks.
- Objects that are high above the
ground such as objects hanging
from above.
- Objects that are out of range of
the center of the vehicle in the hori-
zontal direction.
- Objects that are not perpendic-
ular to the ground.
- The surface of the object is
uneven or wavy.
 When reversing the vehicle, the
functions may not be able to work
properly or may cause a system
malfunction if the following conditions
exist.
High frequency sound from other
sources are nearby:
- Horn sound from another
vehicle.
- Engine sound from other vehi-
cles.
- Sound of an air brake.
- Vehicle detection equipment or a
sonar from another vehicle. - A sound wave with a frequency

similar to the vehicle’s system is
transmitted near by.
- A vehicle equipped with the
same system is reversing toward
your reversing direction.
Weather conditions:
- Extremely high or extremely low
temperatures in which the area near
the sonar sensor becomes too hot
or too cold to operate.
- The sonar sensors or the rear
bumper near the sonar sensors are
exposed to heavy rain or a signifi-
cant amount of water.
- Fog, snow or sandstorm, etc.
- Air is moving rapidly such as
when a strong wind is blowing.
Parts attached to the rear bumper
near the sonar sensor:
- Commercial electr onic parts (fog
light, fender pole, radio antenna) or
commercial attachment parts (trailer
hitch, bicycle carrier, bumper guard)
are attached.
- Parts that emit high frequency
sound, such as a horn or speaker,
are attached.
Vehicle conditions:
- Ice, snow or mud is adhered to
the sonar sensors or the rear
bumper near the sonar sensor.
