Honda Sensing®*
Honda Sensing® is a driver support system which employs the use of two distinctly
different kinds of sensors: a radar sensor lo cated in the front grille and a front sensor
camera mounted to the interior side of the windshield, behind the rearview mirror.
Honda Sensing® has following functions.

Collision Mitigation 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 the
potential for a 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:

TM Conditions and Limitations P. 471
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 504
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 506
1How the system works
Rapid vibrations on the steering wheel alert you
when 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.
When to use
The camera is
located behind
the rearview
mirror.
The radar sensor is
in the front grille.
The system starts monitoring the roadway ahead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you.
The CMBS
TM activates when:●The speed difference between your vehicl e 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 ve hicle or a pedestrian in front of you.

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

The system may automatically shut off and the CMBSTM indicator will come on under
certain conditions. Some examples of thes e conditions are listed below. Other
conditions may reduce some of the CMBS
TM functions.

■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between objects and the background.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Roadway objects or structures are misint erpreted as vehicles and pedestrians.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.
■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving on curvy, winding, or undulating roads.
■CMBSTM Conditions and Limitations1CMBSTM Conditions and Limitations
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).

• The outside of the windshie ld is blocked by dirt, mud, leaves, wet snow, etc.
• The inside of the windshield is fogged.
• An abnormal tire or wheel condition (wrong sized, varied size or construction,
improperly inflated, comp act spare tire, etc.).
• When tire chains are installed.
• The vehicle is tilted due to a heav y load or suspension modifications.
• The camera temperature gets too high.

■Detection limitations
• A vehicle or pedestrian suddenly crosses in front of you.
• The distance between your vehicle and the vehicle or pedestrian ahead of you is
too short.
• A vehicle cuts in front of you at a slow speed, and it brakes suddenly.
• When you accelerate rapidly and approach the vehicl e or pedestrian ahead of you
at high speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved, winding or undulating road that makes it difficult for
the sensor to properly detect a vehicle in front of you.
• The speed difference between your vehicle an d a vehicle or pedestrian in front of
you is significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Another vehicle suddenly comes in front of you at an intersection, etc.
• Your vehicle abruptly crosses over in front of an oncoming vehicle.
• When driving through a narrow iron bridge.
• When the lead vehicl e suddenly slows down.
• 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 shorte r 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 squatting, 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).

Adaptive Cruise Control (ACC)
Helps maintain a constant vehicle speed a nd a set following-interval behind a vehicle
detected ahead of yours, without you having to keep your foot on the brake or the
accelerator.1 Adaptive Cruise Control (ACC)
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when driving on expressways
or freeways and in good weather
conditions.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below 22
mph (35 km/h), ACC will automatically
cancel and no longer will apply your
vehicle’s brakes.
Always be prepared to apply the brake
pedal when conditions require.
When to use
The camera is located
behind the rearview
mirror.
The radar sensor is in the front
grille.
■Vehicle speed for adaptive cruise control: Desired speed in
a range above roughly 25 mph (40 km/h) ~
