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.
2 Customized Features P. 115, 325
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.

Driving
The system becomes ready to start sear ching for lane markings 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 vehicle is not accelerating or braking, and the steering wheel is not being
turned.
• The system makes a determination that the driver is not actively accelerating,
braking or steering.
Press the RDM button to turn the system on
and off.u The indicator in the button comes on and
the message appears on the driver
information interface when the system is
on.

The system may not properly detect lane ma rkings 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 lane lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted 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 interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.

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

• 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.

uuHonda Sensing ®u Front Sensor Camera
Continued
Driving
Front Sensor Camera
The camera, used in systems such as LK AS, RDM, ACC with Low Speed Follow, and
CMBSTM, 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.

The radar sensor is in the lower bumper.1Radar Sensor
Avoid strong impacts to the radar sensor cover.
For the CMBS 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 syst em by using the CMBS OFF
button and take your vehicle to a dealer.

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.

Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can manually or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
position the ignition switch
*1 is in.
Pull the electric parking brake switch up gently
and securely. u The indicator in th e switch comes on.
u The parking brake and brake system
indicator (red) comes on.
■To release
The ignition switch must be ON
(w*1 in order
to release the electric parking brake.
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The indicator in th e switch goes off.
u The parking brake and brake system
indicator (red) goes off.
Manually releasing the parking brake using
the switch helps your ve hicle start slowly and
smoothly when facing down hill on steep hills.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
■Parking Brake1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parki ng brake. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or
release the parking br ake. This is normal.
You cannot apply or release the parking brake if the
12-volt battery goes dead. 2 If the Battery Is Dead P. 583
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four wheels
are applied by the VSA
® system until the vehicle
comes to a stop. The electric parking brake then
applies, and the switch should be released.
In the following situations, the parking brake
automatically operates.
•When your vehicle is stopped with the automatic
brake hold system activated for more than 10
minutes.
•When the driver’s seat belt is unfastened while
your vehicle is stopped and the brake hold system
is applied.
•When the engine is turned off while the brake hold
system is applied.
•When there is a problem with the brake hold
system while brake hold is applied.
•When your vehicle is stopped for more than 10
minutes while ACC with Low Speed Follow is
activated.
