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
