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 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.
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.
Overreliance 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.

Driving
The system activates when all the following conditions are met:
• The vehicle is traveling between about 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.
• The system makes a determination that th e driver is not actively accelerating,
braking, or steering.

Driving
The system may not properly detect lane markings and the position of your vehicle
under certain conditions. Some examples of these conditions are listed below.
■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 la ne lines and the roadway surface.
• 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.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interior of the front windshield.
• Driving at night or in a dark condition such as a tunnel.

■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on a road with temporary lane markings.
• Faint, multiple, or varied lane markings are visible on the roadway due to road
repairs or old lane markings.
• The roadway has merging, split, or crossing lines (e.g., such as at an intersection
or crosswalk).
• The lane markings are extremely narrow, wide, or changing.
• The vehicle in front of you is driving near the lane lines.
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving on rough or unpaved roads, or over bumpy surfaces.
• When objects on the road (curb, guard rail, pylons, etc.) are recognized as white
lines (or yellow lines).
• Driving on roads with double lines.
■Vehicle conditions
• Headlight lenses are dirty or the h eadlights are not properly adjusted.
• The outside of the windshield is streaked or blocked by dirt, mud, leaves, wet
snow, etc.
• The inside of the windshield is fogged.
• The camera temperature gets too high.
• An abnormal tire or wheel condition (inco rrect sizes, varied sizes or construction,
improperly inflated, etc.).
• The vehicle is tilted due to a heavy load or suspension modifications.
• When tire chains are installed.

uuHonda Sensing ®u Front Sensor Camera
Driving
Front Sensor Camera
The camera, used in systems; such as RDM, LKAS, ACC with Low Speed Follow 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 the front grille that could
obstruct the camera’s fiel d of vision and cause the
system to operate abnormally.
Scratches, nicks, and other 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 wind shield, have a dealer
recalibrate the camera. Proper 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.
If the Some Driver Assist Systems Cannot
Operate:Camera Temperature Too High :
message appears:
•Use the climate control system to cool down the
interior and, if necessary, also use defroster mode
with the air flow directed toward the camera.
•Start driving the vehicle to lower the windshield
temperature, which cool s down the area around
the camera.
If the Some Driver Assist Systems Cannot
Operate:Clean Front Windshield : message
appears:
•Park your vehicle in a sa fe place, and clean the
windshield. If the message does not disappear after
you have cleaned the windshield and driven for a
while, have your vehicle checked by a dealer.

The radar sensor is in the front grille.1Radar Sensor
Avoid strong impacts to the radar sensor cover.
For the CMBS
TM to work properly:
•Always keep the radar sensor cover clean.•Never use chemical solvents or polishing powder
for cleaning the sensor cove r. Clean it with water
or a mild detergent.
•Do not put a sticker on th e radar sensor cover or
replace the radar sensor cover.
If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the system by using the CMBS
TM
OFF button and take your vehicle to a dealer.
2 CMBS
TM On and Off P. 510
If the vehicle is involved in any of the following
situations, the radar sensor may not work properly.
Have your vehicle checked by a dealer:
•Your vehicle is involved in a frontal collision.•Your vehicle drives th rough deep water or is
submerged in deep water.
•Your vehicle strongly strikes a bump, curb, chock,
or embankment that coul d jar the radar sensor.
