Driving
Road Departure Mitigation System
Alerts and helps assist you when the syst em detects a possibility of your vehicle
crossing over detected lane markings, or approaching the outer edge of the
pavement (into grass or gravel border) or a detected oncoming vehicle.
The front camera behind the rearview mirror
monitors left and right lane markings in white
or yellow, the outer edge of the pavement
(bordered by grass or gravel) or a detected
oncoming vehicles.
If your vehicle approaches any detected lane
markings, the outer edge of the pavement
(bordered by grass or gravel) or a detected
oncoming vehicles when the turn signals have
not been engaged, the system activates.u If the system cannot de tect lane markings
(in white or yellow), no assistance will be
provided to avoid approaching oncoming
vehicles. In addition to a visual alert, the
system assists with steering and alerts you
with rapid steering wheel vibrations to
help you remain within the detected lane.

■How the System Works
1 Road Departure Mitigation System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Overreliance 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 Mitiga tion system alerts you
when the system detects that you are approaching
the outer edge of the paveme nt (into grass or gravel
border), an oncoming vehicle, or drifting into another
lane without using a turn signal.
The Road Departure Mitigation system may not detect
all lane markings or ever y instance of lane drift.
The Road Departure Miti gation system may not
detect that you are approa ching the outer edge of
the pavement (bordered by grass or gravel) or an
oncoming vehicle.
The Road Departure Mitiga tion system may not be
able to assist you depend ing on weather, speed or
road conditions.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 568

uuHonda Sensing ®u Traffic Sign Recognition System
Driving
Traffic Sign Recognition System
Reminds you of road sign information, such as the current speed limit your vehicle
has just passed through, showing it on the gauge.
When the camera located behind the rear view mirror captures traffic signs while
driving, the system displays the ones that are recognized as designated for your
vehicle. The sign icon will be displayed until the vehicle reaches a predetermined
time and distance.
If the system does not detect any traffic signs while you are driving, the sign icon will
not be displayed.
The sign icon also may switch to another one, or disappear when:
• The end of speed limit or other designated limit is detected.
• You make a turn with a turn signal at an intersection.
■How the System Works
1Traffic Sign Recognition System
Not all signs may be displa yed, but any signs posted
on roadsides should not be ignored. The system does
not work on the designated traffic signs of all the
countries you travel, nor in all situations.
Do not rely too much on the system. Always drive at
speeds appropriate fo r the road conditions.
Never apply a film or attach any objects to the
windshield that could obstruc t the camera’s field of
vision and cause the system to operate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s field of vision can cause the
system to operate abnormally. If this occurs, we
recommend that you replace the windshield with a
genuine Honda replacement windshield. Making even
minor repairs within the ca mera’s field of vision or
installing an aftermarket replacement windshield may
also cause the system to operate abnormally. After
replacing the windshield, have a dealer recalibrate the
camera. Proper calibration of the camera is necessary
for the system to operate properly.
You can read about handling information for the
camera equipped with this system.

Driving
Front Sensor Camera
The camera, used in systems such as La ne Keeping Assist System (LKAS), Road
Departure Mitigation system, Adaptive Cruise Control (ACC) with Low Speed
Follow, Traffic Sign Recognition system, Collision Mitigation Braking System
TM
(CMBSTM), and Traffic Jam Assist, 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.
