Smart Brake Support(SBS)
*
SBS is a system designed to avoid
collisions and reduce damage in the
event of a collision by controlling the
brakes. Sensors and camera equipped
on the vehicle detect objects, and
operate brake control if there is a
possibility of your vehicle colliding with
the object.
One part of the SBS functions when
you are driving forward and the other
part functions when you are driving in
reverse.
Forward drive detection
Forward drive detection has the
following 4 functions.
Forward detection function
*
The forward detection function is
designed to assist the driver in avoiding
collisions with objects (vehicles ahead,
pedestrians, bicycles, and motorcycles)
at the front and to reduce damage in
the event of a collision.
If there is a possibility of your vehicle
colliding with a target object at the
front, you are notified of possible
danger by a screen display and a
warning sound. Furthermore, if the
possibility of a collision increases,
brake control is performed to avoid
collision and reduce damage in the
event of a collision.
In addition, when the driver depresses
the brake pedal, the brakes are applied
firmly and quickly to assist.
Tu r n -A c ro s s Tra ffi c*
The Turn-Across Traffic is designed to
assist the driver in avoiding a collision
with a vehicle approaching in the
opposite direction when making a left
turn at an intersection and to reduce
damage in the event of a collision.
If there is a possibility of your vehicle
colliding with a vehicle approaching in
the opposite direction when you make
a left turn at an intersection, you are
notified of possible danger by a screen
display and a warning sound.
Furthermore, if the possibility of a
collision increases, brake control is
performed to avoid collision and
reduce damage in the event of a
collision.

Front Crossing*
Front Crossing is designed to assist the
driver in avoiding a collision at an
intersection and reduce damage.
If there is a possibility of a collision
with a vehicle at an intersection, brake
control is performed to avoid a
collision or to reduce damage in the
event of a collision.
Intersection accident avoidance assist
function*
Intersection accident avoidance assist
function is designed to avoid collisions
with objects (pedestrians and bicycles)
when making a left or right turn at an
intersection and to reduce damage in
the event of a collision.
If there is a possibility of your vehicle
colliding with a target object when you
make a left or right turn at an
intersection, you are notified of
possible danger by a screen display
and a warning sound. Furthermore, if
the possibility of a collision increases,
brake control is performed to avoid
collision and reduce damage in the
event of a collision.
Reverse drive detection
Reverse drive detection has the
following 2 functions.
Rearward detection function
*
The rearward detection function is
designed to assist the driver in avoiding
collisions with objects at the rear
(obstructions and pedestrians
*) and to
reduce damage in the event of a
collision.
If there is a possibility of your vehicle
colliding with a target object at the
rear, you are notified of possible
danger by a screen display and a
warning sound. Furthermore, if the
possibility of a collision increases,
brake control is performed to avoid
collision and reduce damage in the
event of a collision.

Rear Crossing*
The Rear Crossing is designed to avoid
collision and reduce damage in the
event of a collision with a vehicle
approaching from the rear sides.
If there is a possibility of your vehicle
colliding with a vehicle approaching
from the rear sides, you are notified of
possible danger by a screen display
and a warning sound. Furthermore, if
the possibility of a collision increases,
brake control is performed to avoid
collision and reduce damage in the
event of a collision.
Warnings and Cautions
for Using the Smart Brake Support (SBS)
WARNING
Do not rely completely on the SBS.
The SBS is only designed to reduce
damage in the event of a collision.
Over reliance on the system leading to
the accelerator pedal or brake pedal
being mistakenly operated could result
in an accident.
Heed the following cautions so that
the SBS can operate normally.
Do not modify the suspensions.
 Handle the Forward Sensing Camera
(FSC) appropriately. Otherwise, the
Forward Sensing Camera (FSC) may
not be able to detect target objects,
which could result in an accident.
Refer to Forward Sensing Camera
(FSC) on page 5-127.
 Handle the radar sensors
appropriately. Otherwise, the radar
sensors may not be able to detect
target objects, which could result in
an accident.
Refer to Radar Sensors on page
5-131.
 Handle the ultrasonic sensors
appropriately. Otherwise, the
ultrasonic sensors may not be able to
detect target objects, which could
result in an accident.
Refer to Ultrasonic Sensors on page
5-135.
 Handle the rear camera
appropriately. Otherwise, the rear
camera may not be able to detect
target objects, which could result in
an accident.

Refer to Cameras on page 5-137.
Always check the surrounding area
visually.
The operation of the SBS has certain
limitations. Always confirm the safety
around the vehicle visually when
driving.
CAUTION
 If any of the following conditions is
met, turn the SBS
off to prevent a
mis-operation.
 A trailer is pulled or an accessory
such as a bicycle carrier is installed
to the rear of the vehicle.
 The vehicle is driven on rough
roads such as in areas where there
is grass and foliage or off-road.
 Always use tires of the specified size
and the same manufacturer, brand,
and tread pattern on all 4 wheels. In
addition, do not use tires with
significantly different wear patterns
on the same vehicle. If such
improper tires are used, the SBS may
not operate normally.
How to Use the Smart
Brake Support (SBS)
NOTE
During the SBS brake control, the
brake pedal may move rearward or
become stiff. The brakes are operating,
but continue to depress the brake
pedal.
When the forward detection function
operates*
The forward detection function
operates when all of the following
conditions are met.
(If an object is a vehicle ahead)
The vehicle speed is about 4 km/h
(3 mph) or faster.
(If an object is a bicycle/pedestrian)
The vehicle speed is about 10
km/h to 80 km/h (6.3 mph to 49
mph).
The DSC does not operate.The system determines that there is a
possibility of a collision with an
object ahead.
When the forward detection function
operates, the driver is notified of the
danger by the screen display and
warning sound. Furthermore, if the
possibility of a collision increases,
brake control is performed.
