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
their surroundings for vehicles
or obstacles to avoid a collision.
. The driver is responsible for
driving 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 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.
NOTE
The 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 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-
tion for statistical processing or similar
purposes.
& Reverse Automatic Braking
System overview
The 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.
