■When the system detects a vehicle
Blind spot information System Alert Indicator:
Located near the pillar on both sides.
Comes on when:
•A vehicle enters the alert zone from behind
to overtake you with a speed difference of
no more than 31 mph (50 km/h) from your
vehicle.
• You pass a vehicle with a speed difference
of no more than 12 mph (20 km/h).
Blinks and the beeper sounds when:
You move the turn signal lever in the direction
of the detected vehicle. The beeper sounds
three times.1 Blind spot information System*
The blind spot information system alert indicator may
not come on under the following conditions:
•A vehicle does not stay in the alert zone for more
than two seconds.
•A vehicle is parked in a side lane.•The speed difference betw een your vehicle and the
vehicle you are passing is greater than 6 mph (10
km/h).
•An object not detected by the radar sensors
approaches or passes your vehicle.
•A vehicle running in the adjacent lane is a
motorcycle or other small vehicle.
You can change the setting for the blind spot
information system. 2 Customized Features P. 298
Turn the system off when towing a trailer.
The system may not work properly for the following
reasons:
•The added mass tilts the vehicle and changes the
radar coverage.
•The trailer itself can be detected by the radar
sensors, causing the blind spot information system
alert indicators to come on.

1Blind spot information System*
Blind spot information sy stem may be adversely
affected when:
•Objects (guard rails, poles, trees, etc,.) are
detected.
•An object that does not re flect radio waves well,
such as a motorcycle, is in the alert zone.
•Driving on a curved road.•A vehicle is moving from a far lane to the adjacent
lane.
•The system picks up external electrical interference.•The rear bumper or the sens ors have been improperly
repaired or the rear bu mper has been deformed.
•The orientation of the sensors has been changed.•In bad weather (Heavy rain, snow, and fog).
For a proper blind spot in formation system operation:
•Always keep the rear bumper corner area clean.
•Do not cover the rear bumper corner area with
labels or stickers of any kind.
•Take your vehicle to a deal er if you need the rear
bumper corner area or the radar sensors to be repaired,
or the rear bumper corner area is strongly impacted.

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. 426
• Road Departure Mitigation System 2 P. 460
■The functions wh ich require switch operations to activate
• Adaptive Cruise Control (ACC)

• Lane Keeping Assist System (LKAS) 2 P. 451

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 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 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 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. 430
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 467
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 465
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.
When to use

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.

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
