may be delayed or it may not
operate at all even when a vehicle
is present in a neighboring lane or
approaching 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. When driving in other
countries, certification of the country
where the vehicle is driven must be
obtained. For certification in the U.S.,
refer to“Certification for the BSD/
RCTA”F7-55.!Blind Spot Detection (BSD)
1) Operating range
The system warns the driver of dangers as
follows.
.If the system detects vehicles in the
driver’s blind spots, the BSD/RCTA ap-
proach indicator light(s) on the outside
mirror(s) will illuminate.
.If the driver operates the turn signal
lever to the side where the BSD/RCTA
approach indicator light is illuminated, the
corresponding BSD/RCTA approach indi-
cator light will flash.!Lane Change Assist (LCA)
1) Operating range
The system warns the driver of dangers as
follows.
.If the system detects vehicles ap-
proaching at high speeds in the neighbor-
ing lanes, the BSD/RCTA approach in-
dicator light(s) on the outside mirror(s) will
illuminate.
.If the driver operates the turn signal
lever to the side where the BSD/RCTA
approach indicator light is illuminated, the
corresponding BSD/RCTA approach indi-
cator light will flash.

!Rear Cross Traffic Alert (RCTA)
1) Operating range
The system notifies the driver of another
vehicle approaching from either side when
driving in reverse. This feature helps the
driver check the rear and side areas of the
vehicle when moving backward.
If the system detects a vehicle approach-
ing from either side while moving back-
ward, it warns the driver of dangers in the
following way.
.The BSD/RCTA approach indicator
light(s) on the outside mirror(s) flashes.
.A warning buzzer sounds.!Limitations of the detectability of
RCTA
Since the detectability of RCTA is limited,
the RCTA may not operate properly in
parking areas in which the parking spaces
are drawn diagonally to the driving lanes.
Example 1
1) The detection range of the radar sensors
2) Area out of detection range of the radar
sensors
A) Vehicle that may not be detected
B) Parked vehicle
WARNING
An approaching vehicle (A) may not
be detected because the detection
range is limited by the parked
vehicle (B). Always be sure to checkthe surroundings with your eyes
when reversing the vehicle.
Example 2
1) The detection range of the radar sensors
C) Vehicle that may be detected
NOTE
The system may detect that a vehicle
(C) is passing in front of your vehicle.
Always be sure to check the surround-
ings with your eyes when reversing the
vehicle.

indicator”F7-54..In the following cases, the BSD/
RCTA will temporarily stop operating
(or may stop operating) and the BSD/
RCTA warning indicator will appear.
–When the radar sensor becomes
significantly misaligned (If the or-
ientation of the radar sensor is
shifted for any reason, readjust-
ment is required. Have the sensor
adjusted at a SUBARU dealer.)
–When a large amount of snow or
ice sticks to the rear bumper sur-
face around the radar sensors
–When the vehicle is driven on a
snow-covered road or in an envir-
onment in which there are no
objects around (such as in a desert)
for a prolonged period of time
–When the temperature around
the radar sensors increases exces-
sively due to long driving on uphill
grades in the summer, etc.
–When the temperature around
the radar sensors becomes extre-
mely low
–When the vehicle battery voltage
lowers
–When the vehicle voltage ex-
ceeds the battery voltage rating
The BSD/RCTA will resume operation
once these conditions are corrected,and the BSD/RCTA warning indicator
will disappear. However, if the BSD/
RCTA warning indicator appears for a
prolonged period of time, have the
system inspected at a SUBARU dealer
as soon as possible.

neighboring lane from a lane next to
the neighboring lane
–When driving on a steep incline or
on repeated sharp uphill and downhill
grades
–When going beyond a pass
–When both your vehicle and a
vehicle driving on a neighboring lane
are driving on the far side of each lane.–When several narrowly-spaced ve-
hicles are approaching in a row
