uuHonda Sensing ®u Collision Mitigation Braking SystemTM (CMBSTM)
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.

uuHonda Sensing ®u Collision Mitigation Braking SystemTM (CMBSTM)
Driving
■Automatic shutoff
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 ro ad, or curved and winding 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.

uuHonda Sensing ®u Adaptive Cruise Control (ACC)
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 go od road and 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 ACC: Desired speed in a range above
roughly 25 mph (40 km/h) ~

automatically cancel:
• Bad weather (rain, fog, snow, etc.).
• When the radar sensor behind the emblem gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC range is too close to your vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.

uuHonda Sensing ®u Road Departure Mitigation System
Driving
Road Departure Mitigation System
Alerts and helps to assist you when the sy stem detects a possibility of your vehicle
unintentionally crossing over detected la ne markings and/or leaving the roadway
altogether.
The front camera behind the rearview mirror
monitors left and right lane markings (in white or
yellow). If your vehicle is getting too close to
detected lane markings without a turn signal
activated, the system, in addition to a visual
alert, applies steering torque and alerts you with
rapid vibrations on the steering wheel, to help
you remain within the detected lane.
2 Customized Features P. 298
As a visual alert, the Lane Departure message
appears on the multi-information display.
If the system determines that its steering input
is insufficient to keep your vehicle on the
roadway, it may apply braking.
u Braking is applied only when the lane
markings are solid continuous lines.
The system cancels assisting operations wh en you turn the steering wheel to avoid
crossing over detected lane markings.
If the system operates several times without detecting driver response, the system
beeps to alert you.
■How the System Works
1 Road Departure Mitigation System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Over-reliance on the Road Departure Mitigation
system may result in a collision. It is always your
responsibility to keep the vehicle within your driving
lane.
The Road Departure Mitigation system only alerts you
when lane drift is detected without a turn signal in
use. The Road Departure Mitigation system may not
detect all lane markings or lane or roadway
departures; accuracy will vary based on weather,
speed and lane marker condi tion. It is always your
responsibility to sa fely operate the vehicle and avoid
collisions.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 465
The Road Departure Mitigati on system may not work
properly or may work im properly under the certain
conditions: 2 Road Departure Mitigation system
Conditions and Limitations P. 463
There are times when you may not notice Road
Departure Mitigation system functions due to your
operation of the vehicle, or road surface conditions.

uuHonda Sensing ®u Front Sensor Camera
Continued
Driving
Front Sensor Camera
The camera, used in systems such as LKAS , Road Departure Mitigation system, ACC,
and CMBSTM, is designed to detect an object that triggers any of the systems to
operate their functions.
This camera is located behind the rearview
mirror.
To help reduce the likelihood that high interior
temperatures will cause the camera’s sensing
system to shut off, when parking, find a shady
area or face the front of the vehicle away from
the sun. If you use a reflective sun shade, do
not allow it to cover the camera housing.
Covering the camera can concentrate heat on
it.
■Camera Location and Handling Tips
1 Front Sensor Camera
Never apply a film or attach any objects to the
windshield, the hood, or th e front grille that could
obstruct the camera’s fiel d of vision and cause the
system to operate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s fiel d of vision can cause the
system to operate abnormall y. If this occurs, we
recommend that you replac e the windshield with a
genuine Honda replacem ent windshield. Making
even minor repairs within th e camera’s field of vision
or installing an aftermarket replacement windshield
may also cause the system to operate abnormally.
After replacing the winds hield, have a dealer
recalibrate the camera. Pr oper calibration of the
camera is necessary for the system to operate
properly.
Do not place an object on the top of the instrument
panel. It may reflect onto the windshield and prevent
the system from detecting lane lines properly.
