Driving
Collision Mitigati on Braking SystemTM (CMBSTM)
The system can assist you when it determine s there is a possibility of your vehicle
colliding with a vehicle ahead from behind, an oncoming vehicle in front, a
pedestrian, or someone riding a bicycle (moving bicycle).
The CMBS
TM is designed to alert you when the potential for a collision is determined,
as well as assist in reducing speed, avoiding collisions, and reducing collision
severity.
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It does not prevent collisions
nor stop the vehicle automati cally. It is still your
responsibility to operate th e brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions:
2 CMBS
TM Conditions and Limitations P. 481
You can read about handling information for the
camera equipped with this system. 2 Front Wide View Camera P. 551
When the CMBS
TM is activated, it will continue to
operate even if the accele rator pedal is partially
depressed. However, it w ill be canceled if the
accelerator pedal is fully depressed.

■How the system works
The CMBS
TM will be canceled when your vehicle stops or the system determines
there no longer is the potential for a collision.
The CMBS
TM may also be canceled when a dr iver operates the steering wheel and
the brake or accelerator pe dal to avoid a collision.
1How the system works
The camera in the CMBS
TM is also designed to detect
pedestrians.
However, this pedestrian detection feature may not
activate or may not detect a pedestrian in front of
your vehicle under certain conditions.
Refer to the ones indicating the pedestrian detection
limitations from the list. 2 CMBS
TM Conditions and Limitations P. 481
A front wide view camera is located
behind the rearview mirror.
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and will search for a vehicl e, pedestrian, or moving bicycle in front
of you.
The CMBS
TM activates when:●The speed difference between your vehicle and a vehicle, pedestrian, or moving
bicycle detected in front of you becomes about 3 mph (5 km/h) and over with a
chance of a collision.
●Your vehicle drives at about 18 mph (30 km/h) or less and there is a chance of in
frontal collision with a detected oncoming vehicle when you turn left at an
intersection.
●Your vehicle speed is about 62 mph (100 km/h) or less and the system determines
there is a chance of a collision with:
- An oncoming or stationary vehicle detected in front of you.
- A pedestrian or moving bicycle detected in front of you.

■Examples of other limitations on detection or system operation
• When the vehicle ahead of you is a motorcycle, wheelch air, or other specially-
shaped vehicle.
• When a vehicle is lower in the rear than the front such as trucks that are not
carrying a load, or a narrow vehicle.
• When the vehicle ahead of you, oncoming vehicle, pedestrian or moving bicycle
is not in front of the vehicle.
• The speed difference between your vehi cle and the vehicle ahead of you,
oncoming vehicle, pedestrian or moving bicycle is significantly large.
• When the vehicle or moving bicycle in front of you slows suddenly.
• When the driver operates the brake pedal and steering wheel to avoid a collision.
• When you approach the vehicle ahead of you, oncoming vehicle, pedestrians or
moving bicycles while accelerating rapidl y or operating the steering wheel (except
when turning left at an intersection etc.)
*1
• When the moving bicycle is a child-sized bicycle, folding bicycle, three-wheeler or
other bicycle with small tires, or a long bicycle like a tandem bicycle.
• When the camera cannot correctly identify the shape of the vehicle ahead of you,
oncoming vehicle, pedestrian, or moving bicycle.
• When the minimum ground clearance of a vehicle ahead of you is extremely high.
*1 : When there is a possibility of a frontal collision with the oncoming vehicle while turning left, the CMBSTM
is activated. However, it may not be acti vated if you suddenly turn the steering wheel.

Conditions for assistive driving power suppression.
• When the accelerator is no longer depressed.
• When the accelerator is depressed for approximately four seconds.
• When the brake pedal is depressed.
• When the steering wheel is tu rned and a collision avoided.
Conditions for assistive braking cancellation.
• A certain amount of time ha s passed since activation.
The system may not operate correct ly in the following conditions:
■Examples of obstacles the sonar sensor cannot detect
• Obstacles that do not refl ect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fences, bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Moving objects or obstacles that suddenly enter the road.
• Obstacles that are not pe rpendicular to the ground.
■Conditions for Cancellation
■Low Speed Braking Control System Conditions and Limitations
1Conditions for Cancellation
After Low Speed Braking Control has activated once,
it will not activate again for the same obstacle.
They can be activated again after driving for a certain
distance after last activation.
Low Speed Braking Control ac tivates separately when
moving forward and reversing. (For example, if it
activates when moving forwar d, it can be activated
again immediately if reversing.)
However, if assistive braking has been activated, in
order to activate assistiv e driving power suppression
again, it is necessary to drive for a certain distance to
reset the system.
