PHEV interfere with flat lift
The high voltage battery
is laid out under the floor, so the
undercover is greatly extended downward. Therefore, when
trying to use a flat lift, there is a risk of deformation or
breakage at the undercover due to interference with the plate
of the lift.

5. Rear Sensing System Operation State
• Smart Brake Support (SBS) [rear side sensing
function] (if equipped)
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.
1. 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.
Owner's Manual -> Driving -> Smart Brake Support (SBS)
2. Turn-Across Traffic*
The Turn-Across Traffic is designed to assist the driver in
Page 21 of 56
11/06/2023 02:44 PM tlawrenc
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.
3. 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.
4. 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.
Page 22 of 56
11/06/2023 02:44 PM tlawrenc
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.
1. 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.

2. 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.
Secondary Collision Reduction*
The Secondary Collision Reduction reduces secondary
damage by
decelerating the vehicle when it is damaged in a collision to
the extent that the airbags are deployed while driving.
Owner's Manual -> Driving -> Secondary Collision
If a collision occurs to the extent that the airbags are deployed Reduction
while driving, the hazard warning lights flash to
alert surrounding vehicles and the brakes are controlled to
reduce damage in the event of a collision with an
obstruction or other object.
