uuHonda Sensing ®u Road Departure Mitigation (RDM) System
Driving
Road Departure Mitigation (RDM) 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. 352
As a visual alert, the Lane Departure
message appears on the driver information
interface.
If the system determines that its steering i nput 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 (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. 506
The RDM system may not wo rk properly or may work
improperly under the certain conditions: 2 RDM Conditions and Limitations P. 498
There are times when you may not notice RDM
functions due to your opera tion of the vehicle, or
road surface conditions.
In the following case, a beeper sounds, a message
related to the ACC with Low Speed Follow appears
on the driver information interface, and the braking
function controlled by the RDM system is canceled.
•The vehicle has repeatedly applied the brakes to
maintain the set speed (for example, you are
descending a long slope).

uuHonda Sensing ®u Traffic Sign Recognition System
Driving
Traffic Sign Recognition System
Reminds you of road sign in formation, such as the current speed limit, your vehicle
has just passed through, showing it on the driver information interface and the
head-up display
*.
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.
The sign icon also may switch to another one or disappear when:
• The 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, no r 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 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.

uuHonda Sensing ®u Front Sensor Camera
Driving
Front Sensor Camera
The camera, used in systems such as LKAS, RDM, ACC with Low Speed Follow,
CMBSTM and traffic sign recognition system, 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.

uuParking Your Vehicle uCross Traffic Monitor*
Continued
Driving
Cross Traffic Monitor*
Monitors the rear corner areas using the radar sensors when reversing, and alerts
you if a vehicle approaching from a rear corner is detected.
The system is convenient when you are backing out of a parking space.1Cross Traffic Monitor*
The parking sensor system’s alerting buzzer overrides
the Cross Traffic Monitor buzzer when the sensors
are detecting obstacles at the closest range.
3CAUTION
Cross Traffic Monitor cannot detect all
approaching vehicles and may not detect
an approaching vehicle at all.
Failure to visually confirm that it is safe to
back up the vehicle before doing so may
result in a collision.
Do not solely rely on the system when
reversing; always also use your mirrors, and
look behind and to the sides of your vehicle
before reversing.

Maintenance
Exterior Care
Dust off the vehicle body after you drive.
Regularly inspect your vehi cle for scratches on painted surfaces. A scratch on a
painted surface can result in body rust. If you find a scratch, promptly repair it.
Wash the vehicle regularly. Wash more frequently when driving in the following
conditions:
• If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
• Make sure to follow the instructions indicated on the automated car wash.
• Fold in the door mirrors.
• For models equipped with automatic inte rmittent wipers, turn the wipers off.
• Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. St anding too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.
■Washing the Vehicle
■Using an Automated Car Wash
■Using High Pressure Cleaners
1 Washing the Vehicle
Do not spray water into the air intake vents. It can
cause a malfunction.
Do not spray water onto the fuel fill door directly. A
high-pressure spray ma y cause it to open.
Do not spray water onto the capless unit when the
fuel fill door is open. It ca n cause damage to the fuel
system or engine.
If you need to lift the wiper arms away from the
windshield, first set the wiper arms to the
maintenance position. 2 Changing the Wiper Blade Rubber P. 574
