2017 SUBARU LEGACY light

Starting and operating/BSD/RCTA
BSD/RCTA (if equipped)
The BSD/RCTA consists of rear radar 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.
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 by monitoring the rear and
side areas of the vehicle during a
lane change or reversing. However,
you cannot rely on this system
alone in assuring the safety during
a lane change or reversing. Over-
confidence in this system could
result in an accident and lead to
serious injury or death. Since the
system operation has various limita-
tions, the flashing or illumination of
the BSD/RCTA approach indicator
light may be delayed or it may notoperate 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
following features.
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 ”F 7-61. !
Blind Spot Detection (BSD)
1) Operating range
The system notifies the driver of the
presence of vehicles in its blind spot.
.If the system detects a vehicle in its
blind spot, it warns the driver by illuminat-
ing 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 illuminat-
ing, the system warns the driver of
dangers by flashing the BSD/RCTA ap-
proach indicator light.
7-54

!Lane Change Assist (LCA)
1) Operating range
The system notifies the driver of vehicles
approaching at a high speed in the
neighboring lanes.
.If the system detects a vehicle ap-
proaching at a high speed in the neighbor-
ing lanes, it warns the driver of dangers by
illuminating the BSD/RCTA approach in-
dicator 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 illuminat-
ing, the system warns the driver of
dangers by flashing the BSD/RCTA ap-
proach indicator light. !
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.
. An icon appears on the rear view
camera screen (if equipped) !
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 check

the 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.

may have difficulty detecting the fol-
lowing vehicles and objects.
–Small motorcycles, bicycles, pe-
destrians, stationary objects on the
road or road side, etc. –
Vehicles with body shapes that
the radar may not reflect (vehicles
with lower body height such as a
trailer with no cargo and sports
cars)
– Vehicles that are not approach-
ing your vehicle even though they
are in the detection area (either on a
neighboring lane to the rear or
beside your vehicle when rever-
sing) (The system determines the
presence of approaching vehicles
based on data detected by the radar
sensors.)

NOTE
The Reverse Automatic Braking sys-
tem will operate at vehicle speed
between 1 to 9 mph (1.5 to 15 km/h).
However, stopping the vehicle by auto-
matic hard braking is designed to
operate when the vehicle speed is less
than 3 mph (5 km/h).
&Reverse Automatic Braking
System operation
When Reverse Automatic Braking System
is in operation, an audible warning beeps
will sound in 3 levels to warn the driver of
a potential collision.
1) First braking and warning:
When the system detects an object, if the
vehicle is kept reversing, the system
determines a collision with an object may
occur. In this case, short warning beeps
will sound and automatic deceleration will
be activated. Also, a warning message will
be indicated on the audio/navigation
monitor.

models)
Remember that damage done to
your SUBARU while operating it
off-road and not using common
sense precautions such as those
listed above is not eligible for war-
ranty coverage.
Because of the AWD feature and higher
ground clearance, you can drive your
SUBARU on ordinary roads or off-road.
But please keep in mind that an AWD
SUBARU is a passenger car and is
neither a conventional off-road vehicle
nor an all-terrain vehicle. If you do take
your SUBARU off-road, certain common
sense precautions such as those in the
following list should be taken.
! Before driving
. Make certain that you and all of your
passengers are wearing seatbelts.
. Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.
. Secure all cargo carried inside the
vehicle and make certain that it is not
piled higher than the seatbacks. During sudden stops or jolts, unsecured cargo
could be thrown around in the vehicle and
cause injury. Do not pile heavy loads on
the roof. Those loads raise the vehicle’
s
center of gravity and make it more prone
to tip over.
. Never equip your vehicle with tires
larger than those specified in this manual.
! During driving
General precautions:
. Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain.
. Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and
the like.
. Do not drive across steep slopes.
Instead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep.
. Avoid sharp turning maneuvers, espe-
cially at higher speeds.
. Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead,
drive with your fingers and thumbs on
the outside of the rim. .
Do not drive or park over or near
flammable materials such as dry grass or
fallen leaves, as they may burn easily. The
exhaust system is very hot while the
engine is running and right after the
engine stops. This could create a fire
hazard.
Precautions when driving under espe-
cially dangerous situations:
. If driving through water, such as when
crossing shallow streams:
–First, check the depth of the water
and the bottom of the stream bed for
firmness.
– Next, ensure that the bed of the
stream is flat.
– Then, drive slowly and completely
through the stream. The water should
be shallow enough that it does not
reach the vehicle’ s undercarriage.
. Water entering the engine air intake or
the exhaust pipe or water splashing onto
electrical parts may damage your vehicle
and may cause it to stall. Never drive
through rushing water. Regardless of its
depth, it can wash away the ground from
under your tires, resulting in possible loss
of traction and even vehicle rollover.
. If you must rock the vehicle to free it
from sand or mud, depress the accelerator
pedal slightly and move the shift lever/
