aligned, a system malfunction
may occur, including the inability
to detect vehicles entering the
detection areas. If any strong
shock is applied to the bumper,
be sure to contact your SUBARU
dealer for inspection.
–Do not disassemble the radar
sensors.

tance.
Reverse Automatic Braking
System (if equipped)Reverse Automatic Braking 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 direction, the system will
notify the driver with a warning sound and
may activate the vehicle’s brakes auto-
matically.
WARNING
.Reverse Automatic Braking is not
a system intended to replace the
driver’s responsibility to check
surrounding areas for vehicles or
obstacles to avoid a collision.
.The driver is responsible for driv-
ing safely. Always be sure to
check the surroundings visually
when reversing the vehicle.
.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..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.
NOTEThe Reverse Automatic Braking Sys-
tem records and stores the following
data when automatic braking operates.
It does not record conversations, per-
sonal 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 con-
tracted by SUBARU may acquire
and use the recorded data for the
purpose of vehicle research and
development. SUBARU and third
parties contracted by SUBARU will

not disclose or provide 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
identified is provided to a research
institution for statistical processing
or similar purposes.
&Reverse Automatic Braking
System overviewThe system detects objects using sonar
sensors installed in the rear bumper. If the
system determines a possible collision
with an object in the reversing direction,
automatic deceleration will be activated.
Also, beeping sounds will activate. If the
vehicle is further reversed, automatic hard
braking will be applied and a continuous
beeping sound will activate.!Detecting range
1) Detecting range (width): Approximately 6
in (15 cm) outside of the vehicle width
2) Range that the system cannot detect:
Approximately 20 in (50 cm) behind the
rear of the vehicle
3) Detecting range (length): Approximately
5 ft (1.5 m) from the rear of the vehicle
WARNING
If your vehicle is trapped on a rail-
road crossing and you are trying to
escape by reversing through the
crossing gate, the system may re-
cognize the crossing gate as an
obstacle and the brakes may acti-
vate. In this case, remain calm and
either continue to depress the accel-
erator pedal or cancel the system. Tocancel the system, refer to“Cancel-
ing the Reverse Automatic Braking
system operation”F7-74.

per near the sonar sensor–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 guaran-
tee 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 oper-
ate.
.The system may not be able to detect
the following objects
–Sharp or thin objects such as
poles, fences and ropes which may
not reflect the sound 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.
