Honda Sensing®
Honda Sensing® is a driver support system which employs the use of two distinctly
different kinds of sensors: a radar sensor located behind the emblem and a front
sensor camera mounted to the interior side of the windshield, behind the rearview
mirror.
Honda Sensing ® has following functions.
■The functions which do not requir e switch operations to activate
• Collision Mitigation Braking SystemTM (CMBS)TM 2 P. 420
• Road Departure Mitigation (RDM) System 2 P. 454

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 CMBSTM is designed to reduce the severity of an
unavoidable collision. It does not prevent a collision 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 CMBS
TM may not activate or may not detect a
vehicle in front of your vehicle under certain conditions:
2 CMBSTM Conditions and Limitations P. 424
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 461
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 459
1How the system works
Rapid vibrations on the st eering 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 colli sion is not determined.
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. The radar sensor is
behind the emblem.
The CMBS
TM 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. The camera is
located behind the
rearview mirror.

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.

The system may automatically shut off and the CMBSTM indicator will come on under
certain conditions. Some examples of th ese conditions are listed below. Other
conditions may reduce some of the CMBS
TM functions.
2 Front Sensor Camera P. 459
■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 reflected 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 (obscured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on curvy, winding, or undulating roads.
• The road is hilly or the vehicle is approaching the crest of a hill.
■CMBSTM Conditions and Limitations

■Vehicle conditions
• Headlight lenses are dirty or the h eadlights are not properly adjusted.
• The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.
• The inside of the windshield is fogged.
• An abnormal tire or wheel condition (wro ng sized, varied size or construction,
improperly inflated, co mpact spare tire, etc.).
• When tire chains are installed.
• The vehicle is tilted due to a heavy load or suspension modifications.
• The camera temperature gets too high.
• Driving with the parking brake applied.
• When the radar sensor behind the emblem gets dirty.
• The vehicle is towing a trailer.

■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 vehicle 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 vehicle suddenly slows down.

Driving
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 havi ng to keep your foot on the brake or the
accelerator.1 Adaptive Cruise Control (ACC)
ACC can not be activated if Intelligent Traction
Management settin g is snow, sand
* or mud*.
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
■Vehicle speed for adaptive cruise control: Desired speed in a
range above roughly 25 mph (40 km/h) ~
■Gear positions for adapti ve cruise control: In (D or (S
The radar sensor is behind
the emblem.
The camera is located
behind the rearview
mirror.
