Collision Mitigation Braking SystemTM (CMBSTM)
1Collision Mitigation Braking SystemTM (CMBSTM)
The system can assist you when it determines there is a possibility of your vehicle
colliding with a vehicle (including motorcycles) ahead from behind, an oncoming
vehicle in front, a pedestrian, or someone riding a bicycle (moving bicycle). The
CMBSTM 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.
Important Safety Reminder
The CMBSTM is designed to reduce the severity of an
unavoidable collision. It does not prevent collisions
nor stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately according to the driving
conditions.
The CMBSTM may not activate or may not detect a
vehicle in front of your vehicle under certain
conditions:

■ How the system works
When to use
A front sensor camera
is located behind the
rearview mirror.
The radar sensor is behind
the Honda emblem on the
front grille.
The system starts monitoring the roadway ahead when your vehicle speed is about
3 mph (5 km/h) or above and will search for a vehicle, pedestrian, or moving bicycle
in front of you.
The CMBSTM 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.
The CMBSTM will be canceled when your vehicle stops or the system determines
there no longer is the potential for a collision.
The CMBSTM may also be canceled when a driver operates the steering wheel and
the brake or accelerator pedal to avoid a collision.

■ When the system activates
1When the system activates
The camera in the CMBSTM is also designed to detect
pedestrians.
The system provides visual and audible alerts of a possible collision, and stops if the
collision is avoided.
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.
u Take appropriate action to prevent a collision (apply the brakes, change
lanes, etc.).

CMBSTM On and Off
■
You can turn the system on and off using the driver information interface.
2 Safety Support P. 124
The CMBSTM may automatically shut off, and the
safety support indicator (amber) will come and stay
on under certain conditions:
The CMBSTM is turned on every time you start the engine, even if you turned it off
the last time you drove the vehicle.
2 CMBSTM Conditions and Limitations P. 474
When the CMBSTM is activated, it will continue to
operate even if the accelerator pedal is partially
depressed. However, it will be canceled if the
accelerator pedal is fully depressed.
The Vehicle Stability AssistTM (VSA®) system, brake
system (Amber), Adaptive Cruise Control (ACC) with
Low Speed Follow, low tire pressure/TPMS* and
safety support indicators may come on in amber
along with a message in the gauge when you set the
power mode to ON after reconnecting the battery.
Drive a short distance at more than 12 mph (20 km/h).
Each indicator should go off. If any do not, have your
vehicle checked by a dealer.

■ Examples of limitations on the correct detection of the camera due to the
condition of the vehicle ahead of you, oncoming vehicles, pedestrians, or
moving bicycles
• The distance between your vehicle and the vehicle ahead of you, oncoming
vehicle, pedestrian, or moving bicycle ahead of you is too short.
• The vehicle ahead of you, oncoming vehicle, pedestrian, or moving bicycle
suddenly cuts in front of or jumps out in front of you.
Make sure that all the tires are of the same specified
size, type and brand, and that they are evenly worn. If
you use tires of different sizes, types, brands, or degree
of wear, the system may not work properly.
Do not modify the suspension. Altering the height of
the vehicle may prevent the system from working
properly.
• The bicycle is stopped.
• The oncoming vehicle or vehicle ahead of you is sideways or facing diagonally.
• When the vehicle ahead of you, oncoming vehicle, pedestrian, or moving bicycle
blends in with the background, preventing the system from recognizing them.
• When several pedestrians are moving ahead of you in a group.
• When several bicycles are moving ahead of you in a group.
• When a pedestrian or moving bicycle crosses the road too quickly.
• A pedestrian or moving bicycle approaches from the opposite direction.
• The headlights of the vehicle ahead of you or oncoming vehicle are lit on one side
or not lit on either side in a dark place.
• When part of a pedestrian (heads, limbs, etc.) is hidden by load.
• When a pedestrian is bent over or squatting, when their hands are raised, or they
are running.
• When the pedestrian is shorter than about 3.3 feet (1 meter) or taller than about
6.6 feet (2 meters) in height.
• When the pedestrian is pushing a stroller or bicycle.

■ Examples of other limitations on detection or system operation
• When the vehicle ahead of you is a small motorcycle, motorcycle with a sidecar,
wheelchair, 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 vehicle 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 rapidly 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 radar and 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.
• When turning left or right and your turn signal is not activated in the same
