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.
.Since the system operation has
various limitations, the warning
sound or automatic braking may
be delayed or may not operate at
all even when an obstacle is
present in the reversing direc-
tion.
.The system is not designed todetect 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 be compro-
mised.
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 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 provide
the acquired data to any other third

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 acti-
vate.
.If the vehicle is further reversed, auto-
matic 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 brake may activate.
In this case, remain calm and either
continue to depress the accelerator
pedal or cancel the system. Tocancel the system, refer to“Cancel-
ing the Reverse Automatic Braking
system operation”F7-67.
