lowing functions.
To detect a vehicle in a blind
spot on an adjacent lane or a
vehicle approaching at high
speed while driving the vehi-
cle (Blind Spot Detection)
 To detect a vehicle approach-
ing from the right or left while
reversing the vehicle (Rear
Cross Traffic Alert)
The system uses radar sensors
for the following features.
The BSD/RCTA radar sensor has
been certified by the radio wave
related laws of the U.S. and other
FCC compliant countries and Can-
ada. When drivi ng in other coun-
tries, certification of the country
where the vehicle is driven must be
obtained. For certif ication in the U.S.
and other FCC comp liant countries
and Canada, refer to P.440.
■Blind Spot Detection (BSD)
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 illuminating the
BSD/RCTA approach indica-
tor(s) on the outside mirror(s).
 If the driver operates the turn
signal lever in the direction
where the BSD/RCTA
approach indicator is illumi-
nating, the system warns the
BSD/RCTA*
The BSD/RCTA consists of
rear corner radars with
Blind Spot Detection, Lane
Change Assist and Rear
Cross Traffic Alert.
These functions of
BSD/RCTA are the systems
that detect objects and vehi-
cles to the rear and draw
attention to the driver when
changing a lane or when
driving in reverse.
WARNING
The driver is responsible for driv-
ing 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 limitations, the flash-
ing or illumination of the
BSD/RCTA approach indicator
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 pay-
ing attention to t he rear and side
areas of the vehicle.

Reverse Automatic
Braking (RAB) system*
Reverse Automatic Braking
(RAB) is a system designed
to help avoid collisions or
reduce collision damage
when reversing the vehicle.
If a wall or an obstacle is
detected in the reversing
direction, the system will
notify the driver with a
warning sound and may
activate the vehicle’s brakes
automatically.

enforceable request.
●Data that has been modified so
that the user and vehicle cannot
be identified is provided to a
research institution for statistical
processing or similar purposes.
The Reverse Automatic Braking
(RAB) system will operate the
following 2 functions using 4
sonar sensors.
Sonar Audible Alarm
The Reverse Automatic Braking
(RAB) system detects objects rear-
ward and warns the driver by warn-
ing message on the multimedia
system screen an d warning beeps.
Automatic Braking
The automatic braking detects
objects rearward and if there is a
high risk of a co llision, the system
decelerates the vehicle and con-
trols the braking to reduce damage.

WARNING
●Reverse Automatic Braking
(RAB) is not a system intended
to replace the driver’s responsi-
bility to check their surroundings
for vehicles or obstacles to
avoid a collision.
●The driver is responsible for
driving safely. Before reversing,
be sure to first depress the
brake pedal and visually check
the surroundings.
●There are some cases in which
the vehicle cannot avoid colli-
sion, because the system oper-
ation has limitations. The
warning sound or automatic
braking may be delayed or may
not operate at all even when an
obstacle is present.
●Make sure to set the Automatic
Braking to OFF when the vehi-
cle is on the free roller or on the
chassis dynamometer. Other-
wise, the vehicle may move and
it may cause an accident.
●Make sure to set the Automatic
