■Automatic cancellation
The beeper sounds and a message appears on the driver information interface when
ACC is automatically canceled. Any of these conditions may cause the ACC to
automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the lower bump er next to the fog light 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.
• When the Maximum Load Limit is exceeded.
• When passing through an enclos ed space, such as tunnel.
• Ignoring shift down indication shown in the tachometer display will cancel the
ACC after about 10 seconds.
• The engine speed goes into the tachometer’s red zone.
• The engine speed goes to below 1,000 rpm.
• You shift into neutral temporarily when shifting into a higher or lower gear.
1Automatic cancellation
Even though ACC has been automatically canceled,
you can still resume the prior set speed. Wait until the
condition that caused ACC to cancel improves, then
press the –/SET button.
When you completely disable VSA® while ACC is
activated, ACC will automatically be canceled.

uuHonda Sensing ®u Lane Keeping Assist System (LKAS)
Continued
Driving
Lane Keeping Assist System (LKAS)
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides tactile and visual al erts if the vehicle is detected drifting out of its lane.1Lane Keeping Assist System (LKAS)
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicl e control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
2 Driver Information Interface Warning and
Information Messages P. 104
Do not place objects on the instrument panel.
Objects may reflect on th e windshield and prevent
correct detection of the traffic lanes.
The LKAS only alerts you when lane drift is detected
without a turn signal in use. The LKAS may not detect
all lane markings or lane departures; accuracy will
vary based on weather, speed, and lane marker
condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly or may work
improperly under the certain conditions:
2 LKAS Conditions and Limitations P. 538
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 546
When you operate the turn signals to chan ge lanes, the system is suspended, and
resumes after the signals are off.
If you make a lane change without operating the turn signals, the LKAS alerts
activate, and torque is applied to the steering.
■Front Sensor
Camera
Monitors the
lane lines■Tactile and visual alerts
Rapid vibrations on the steering wheel
and a warning display alert you that
the vehicle is drifting out of a detected
lane.
■Steering input assist
The system applies torque to the steering to keep the vehicle between the left
and right lane lines. The applied torque becomes stronger as the vehicle gets
closer to either of the lane lines.

uuHonda Sensing ®u Road Departure Mitigation (RDM) System
Continued
Driving
Road Departure Mitigation (RDM) System
Alerts and helps to assist you when the system detects a possibility of your vehicle
unintentionally crossing over detected lane 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 vehicl e 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. 134, 350
As a visual alert, the Lane Departure
message appears on the driver information
interface.
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 with out detecting driver response, the system
beeps to alert you.
■How the System Works
1 Road Departure Mitigation (RDM) System
Important Safety Reminder
Like all assistance systems, the RDM system has
limitations.
Over-reliance on the RDM system may result in a
collision. It is always your responsibility to keep the
vehicle within your driving lane.
The RDM system only alerts you when lane drift is
detected without a turn signal in use. The RDM
system may not detect all la ne markings or lane or
roadway departures; accu racy will vary based on
weather, speed and lane marker condition. It is
always your responsibilit y to safely operate the
vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system.
2 Front Sensor Camera P. 546
The RDM system may not wo rk properly or may work
improperly under the certain conditions: 2 RDM Conditions and Limitations P. 544
There are times when you may not notice RDM
functions due to your opera tion of the vehicle, or
road surface conditions.
1 How the System Works
The RDM system does not function while VSA ® is
completely disabled.

uuHonda Sensing ®u Front Sensor Camera
Driving
Front Sensor Camera
The camera, used in system s such as LKAS, RDM, ACC*, ACC with Low Speed
Follow*, CMBSTM and auto high-beam, is designed to detect an object that triggers
any of the systems to operate its 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.
