7-20. BSD/RCTA (If

Equipped)

s07bm

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.

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 rever-

sing safely by monitoring the rear

and side areas of the vehicle. How-

ever, you cannot rely on this system

alone in assuring the safety during a

lane change or reversing. Overcon-

fidence in this system could result in

an accident and lead to serious

injury or death. Since the system

operation has various limitations,

the flashing or illumination of the

BSD/RCTA approach indicator light

may be delayed or it may not operate

at all even when a vehicle is present

in a neighboring lane or approach-

ing from either side.

The driver is responsible for paying

attention to the rear and side areas

of the vehicle.

& System Features

s07bm01

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 rear corner radars for the

following features.

NOTE

The BSD/RCTA radar sensor has been

certified by radio wave-related laws

applicable in the U.S. and other FCC-

compliant countries, including Canada.

When driving your vehicle in countries

other than the U.S. and Canada, you

must obtain certification for the coun-

try where you are driving the vehicle.

For more information on certification in

the U.S. and other FCC compliant

countries, including Canada, refer to

“Certification for the BSD/RCTA”

�P413.

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 illuminating, the

system warns the driver of dangers by

flashing the BSD/RCTA approach indica-

tor light.

! Rear Cross Traffic Alert (RCTA)

s07bm0103

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 center informa-

tion display.

! Limitations of the detectability of

RCTA

s07bm010301

Since the detectability of RCTA is limited,

the RCTA may not operate properly in

angled parking.

Example 1

1) The detection range of the rear corner

radars

2) Area out of detection range of the rear

corner radars

A) Vehicle that may not be detected

B) Parked vehicle

7-21. Reverse Automatic

Braking (RAB) System (If

Equipped)

s07bn

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.

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 driv-

ing 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 opera-

tion 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 function to OFF when the

vehicle 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

Braking function to OFF when

towing a trailer. Otherwise, the

vehicle may move and it may

cause an accident.

. The system is not designed to

detect people (including chil-

dren), animals or other moving

objects.

. Depending on the vehicle condi-

tion or the surrounding environ-

ment, the sonar sensor’s ability

to detect objects may become

unstable.

NOTE

The Reverse Automatic Braking (RAB)

system records and stores the follow-

ing data when automatic braking oper-

ates. It does not record conversations,

personal information or other audio
