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.

BSD/RCTA (If Equipped)
269
Starting and Operating7
– 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.
