BSD/RCTA (if equipped)
The BSD/RCTA consists of rear corner
radars with Blind Spot Detection and Rear
Cross Traffic Alert.
These functions enable the system to
detect objects or vehicles to the rear,
drawing attention to the driver when
changing a lane or when driving in reverse.
WARNING
The driver is responsible for driving
safely. Always be sure to check the
surroundings with your eyes when
changing lanes or reversing the
vehicle.
The system is designed to assist the
driver to change lanes or reverse
safely by monitoring the rear and
side areas of the vehicle. However,
you cannot rely on this system alone
in assuring the safety during a lane
change or reversing. Overconfi-
dence in this system could result in
an accident and lead to serious
injury or death. Since the system
operation has various limitations,
the flashing or illumination of the
BSD/RCTA approach indicator light
may be delayed or it may not operate
at all even when a vehicle is present
in a neighboring lane or approach-
ing from either side.
The driver is responsible for paying
attention to the rear and side areas
of the vehicle.
&
System features
BSD/RCTA consists of the following func-
tions.
.
To detect a vehicle in a blind spot on an
adjacent lane or a vehicle approaching at
high speed while driving the vehicle (Blind
Spot Detection)
.
To detect a vehicle approaching from
the right or left while reversing the vehicle
(Rear Cross Traffic Alert)
The system uses radar sensors for the
above functions.
NOTE
The BSD/RCTA radar sensor has been
certified by the radio wave related laws
of the U.S. and Canada. When driving in
other countries, certification of the
country where the vehicle is driven
must be obtained. For certification in
the U.S. and Canada, refer to “Certifica-
tion for the BSD/RCTA”

Reverse Automatic Braking
(RAB) system (if equipped)
Reverse Automatic Braking (RAB) system
is a system designed to help avoid colli-
sions 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 automatically.
WARNING
.
Reverse Automatic Braking
(RAB) system is not a system
intended to replace the driver’s
responsibility to check surround-
ing areas for vehicles or obsta-
cles to avoid a collision.
.
The driver is responsible for driv-
ing 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.
.
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 be compro-
mised.
.
Do not remove the SUBARU gen-
uine navigation and/or audio sys-
tem. If the SUBARU genuine
navigation and/or audio system
is removed, the rear view camera
image and help lines (distance
marker, dynamic guidelines and
vehicle width lines) will no longer
be displayed.
.
Even if the Reverse Automatic
Braking (RAB) system and object
detection warning is ON, the
visible alert of Reverse Auto-
matic Braking (RAB) system will
not be displayed. However, the
audible alert and its function will
operate.

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.
.
Objects the system is not designed
to detect.
– Pedestrians
– Moving objects including moving
vehicles
– Objects which absorb 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
horizontal direction.
– Objects that are not perpendicu-
lar to the ground.
– The surface of the object is
uneven or wavy.
.
The system may not be able to
properly detect objects or may cause
a system malfunction when the follow-
ing 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 nearby.
– 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 rear bumper near the sonar
sensors is exposed to heavy rain or
a significant amount of water.
– Fog, snow or sandstorm, etc.
– Air is moving rapidly such as
when a strong wind is blowing.
