Driving
Collision Mitigati on Braking SystemTM (CMBSTM)
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM is designed to alert you when a
potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It do es not prevent a collision
nor stop the vehicle automati cally. It is still your
responsibility to operate the 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. 434
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 385
Be careful not to severely impact the radar sensor
cover.
1 How the system works
Rapid vibrations on the steering wheel alert you
when the your vehicle speed is between 19 and 62
mph (30 and 100 km/h) with an oncoming vehicle
detected in front of you.
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential coll ision is not determined.
The radar sensor is
behind the emblem.
The 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 there is a vehicle in front of you.
When to use
The CMBSTM activates when:●The speed difference between your vehicle and a vehicle or pedestrian detected
in front of you becomes about 3 mph (5 km/h) and over with a chance of a
collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you.

■When the system activates
At system’s earliest collision alert st age, you can change the distance (Long/
Normal /Short ) between vehicles at which alerts will come on through audio/
information screen setting options.
2 Customized Features P. 296
■Vibration alert on the steering wheel
When a potential coll ision to an oncoming detected vehicle is determined, the
system alerts you with rapid vibration on th e steering wheel, in addition to visual and
audible alerts. u Take appropriate action to prevent a col lision (apply the brakes, operate the
steering wheel, etc.).
1 When the system activates
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

The system provides visual, audible and tactile alerts of a possible collision, and
stops if the collision is avoided.

The system has three alert stages for a possible collision. However, depending on circumstances, the CMBSTM may not go through all of
the stages before initiating the last stage.

Press and hold the button until the beeper
sounds to switch the system on or off.
When the CMBS
TM is off:
• The CMBSTM indicator in the instrument
panel comes on.
• A message on the driver information
interface reminds you th at the system is off.
The CMBS

the power system, even if you turned it off the
last time you drove the vehicle.

• When there is a group of people in front of your vehicle walking together side by
side.
• Surrounding conditions or belongings of the pedestrian alter the pedestrian’s
shape, preventing the system from recogn izing that the person is a pedestrian.
• When the pedestrian is shorter than about 3.3 feet (1 meter) or taller than about
6.6 feet (2 meters) in height.
• When a pedestrian blends in with the background.
• When a pedestrian is bent over or squa tting, or when their hands are raised or
they are running.
• When several pedestrians are walking ahead in a group.
• When the camera cannot correctly identify that a pedestrian is present due to an
unusual shape (holding luggage, body position, size).
■Automatic shutoff
The CMBSTM may automatically shut itself off and the CMBSTM indicator comes and
stays on when:
• The temperature inside the system is high.
• You drive off-road or on a mountain road, or curved and wi nding road for an
extended period.
• An abnormal tire condition is detected (wrong tire size, flat tire, etc.).
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
Once the conditions that caused the CMBS
TM to shut off improve or are addressed
(e.g., cleaning), the system comes back on.

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)
Driving
The CMBSTM may activate even when you are aware of a vehicle ahead of you, or
when there is no vehicle ahead. Some examples of this are:
■When Passing
Your vehicle approaches another vehicle ah ead of you and you change lanes to pass.
■At an intersection
Your vehicle approaches or passes another ve hicle that is making a left or right turn.
■On a curve
When driving through curves, your vehicle comes to a point where an oncoming
vehicle is right in front of you.
■Through a low bridge at high speed
You drive under a low or na rrow bridge at high speed.
■Speed bumps, road work sites, train tracks, roadside objects, etc.
You drive over speed bumps, st eel road plates, etc., or your vehicle approaches train
tracks or roadside objects [such as a traffi c sign and guard rail] on a curve or, when
parking, stationary vehicles and walls.
■With Little Chance of a Collision1 Collision Mitigation Braking SystemTM (CMBSTM)
For the CMBS
TM to work properly:
Always keep the radar sensor cover clean.
Never use chemical solvents or polishing powder for
cleaning the sensor cover. Clean it with water or a
mild detergent.
Do not paint, or apply any coverings or paint to radar
sensor area. This can impact CMBS
TM operation.
Have your vehicle checked by an authorized Honda
Clarity Electric dealer if you find any unusual behavior
of the system (e.g., the wa rning message appears too
frequently).
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehicle checked by an authorized
Honda Clarity Electric dealer:
•The vehicle impacted a bump, curb, chock,
embankment, etc.
•You drive the vehicle where the water is deep.
•Your vehicle has a frontal collision.
