BSD/RCTA (If Equipped)
2687-20. BSD/RCTA (If Equipped)The BSD/RCTA consists of rear corner
radars with Blind Spot Detection and Rear
Cross Traffic Alert.
These functions of BSD/RCTA are the
systems that detect objects and vehicles
to the rear and draw attention to the driver
when changing a lane or when driving in
reverse.
■ System FeaturesBSD/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

following features.
NOTEThe BSD/RCTA radar sensor has been
certified by the radio wave related laws
of the U.S. and other FCC compliant
countries, Canada and Mexico. When
driving in other countries, certifica-
tion of the country where the vehicle is
driven must be obtained. For certifica-
tion in the U.S. and other FCC compli-
ant countries, Canada and Mexico,
refer to "Certification for the BSD/
RCTA" P274.
▼ Blind Spot Detection (BSD)1) Operating range
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 in changing lanes or
reversing 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.
Overconfidence in this system
could result in an accident and lead
to serious injury or death. Since the
system operation has various lim-
itations, the flashing or illumination
of the BSD/RCTA approach indica-
tor light may be delayed or it may
not operate at all even when a vehi-
cle 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.

– CONTINUED –
The system notifies the driver of the pres-
ence of vehicles in its blind spot.
If the system detects a vehicle in its
blind spot, it warns the driver by illumi-
nating the BSD/RCTA approach indicator
light(s) on the outside mirror(s).
 If the driver operates the turn signal
lever in the direction where the BSD/
RCTA approach indicator light is illumi-
nating, the system warns the driver of
dangers by flashing the BSD/RCTA
approach indicator light.
▽ Lane Change Assist (LCA)1) Operating rangeThe system notifies the driver of vehicles
approaching at a high speed in the neigh-
boring lanes. 
If the system detects a vehicle
approaching at a high speed in the neigh-
boring lanes, it warns the driver of
dangers by illuminating the BSD/RCTA
approach indicator light(s) on the outside
mirror(s).
 If the driver operates the turn signal
lever in the direction where the BSD/
RCTA approach indicator light is illumi-
nating, the system warns the driver of
dangers by flashing the BSD/RCTA
approach indicator light.
▼ Rear Cross Traffic Alert (RCTA)
1) Operating rangeThe 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
approaching from either side while moving
backward, 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.
 An icon appears on the center informa-
tion display.
▽Limitations of the detectability
of RCTA
Since the detectabilit y of RCTA is limited,
the RCTA may not operate properly in
angled parking.

the following conditions are met.
 The ignition switch is in the “ON” posi-
tion.
 The BSD/RCTA warning indicator and
BSD/RCTA OFF indicator are turned off.
 The vehicle is driven at speeds above
7 mph (12 km/h) (except when reversing).
 The shift lever/select lever is in the “R”
position (RCTA only).
The BSD/RCTA will not operate in the
following situations.
 The BSD/RCTA OFF indicator
appears.
 The vehicle speed is below 6 mph (10
km/h) even when the BSD/RCTA OFF
indicator does not appear (except when
reversing).
NOTE In the following cases, the BSD/
RCTA will stop operating and the BSD/
RCTA warning indicator will appear. - When a malfunction occurs in
the system, including the BSD/
RCTA approach indicator light
 If the BSD/RCTA warning indicator
appears, exercise proper caution. For
details, refer to "BSD/RCTA Warning
Indicator" P274.
 In the following cases, the BSD/
RCTA will temporarily stop operating
(or may stop operating) and the BSD/
RCTA OFF indicator will appear. - When the radar sensor becomes
significantly misali gned (If the orien-
tation of the radar sensor is shifted
for any reason, readjustment is
required. Have the sensor adjusted
at a SUBARU dealer.)
- When a large amount of snow or
ice sticks to the rear bumper surface
around the radar sensors
- When the vehicle is driven on a
snow-covered road or in an environ-
ment 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.
WARNING
An approaching vehicle (A) may not
be detected because the detection
range is limited by the parked vehi-
cle (B). Always be sure to check the
surroundings with your eyes when
reversing the vehicle.

▼ Safety tips regarding the BSD/
RCTA approach indicator light/
warning buzzer
 In the following cases, operation of the
BSD/RCTA approach indicator light and
the warning buzzer may be delayed or the
system may fail to issue these warnings.
- When a vehicle moves to the neigh-
boring 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
vehicles are approaching in a row
- In low radius bends (tight bends or
when making turns at an intersection)
- When there is a difference in height
between your lane and the neighboring
lane
- Immediately after the BSD/RCTA is
activated by touching “BSD/RCTA”
- Immediately after the shift lever/
select lever is shifted to the “R” position
- When extremely heavy cargo is
loaded in the trunk
 During reversing, operation of the BSD/
RCTA approach indicator light and the
warning buzzer may be delayed or the
system may fail to issue these warnings
under the following conditions.
- When backing out of an angled
parking space
- When a large-sized vehicle is
parked next to your vehicle (That
vehicle prevents the propagation of
radar waves.)
