1How the System Activates
The RDM system may automa tically shut off and the
safety support indicator (a mber) comes and stays on.
2 Indicators P. 78
RDM system function can be impacted when the
vehicle is:
•Not driven within a traffic lane.
•Driven on the inside edge of a curve, or outside of
a lane.
•Driven in a narrow lane.

Driving
When you turn the RDM on and off, do the
following.
1. Press the safety support switch.
2. Roll the left selector wheel to the
symbol and push it.
u The message appears on the driver
information interface when the system
becomes on or off.
The RDM is in the previously selected ON or
OFF setting each time you start the engine.
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 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 interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.
■RDM On and Off1RDM On and Off
When you have selected Warning Only from the

■Roadway conditions
• Driving on a snowy or wet roadway (obscured 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 extremel y 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).

• 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 (wro ng sized, varied size or construction,
improperly inflated, co mpact spare tire, etc.).

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 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, 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 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.

If the system does not detect any traffic signs while you are driving, the image below
may appear.1Traffic Sign Recognition System
To help reduce the likel ihood 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.
If the Some Driver Assist Systems Cannot
Operate: Camera Temperature Too High message
appears, the traffic sign recognition system does not
work, and will be displayed.
•Use the climate control system to cool down the
interior and, if necessary, also use defroster mode
with the air flow directed towards 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, the traffic sign recognition system does not
work, and will be displayed.
Park your vehicle in a safe place, and clean the
windshield. If the message does not disappear after
you have cleaned the winds hield and driven for a
while, have your vehicl e checked by a dealer.

The traffic sign recognition system may not operate correctly, such as displaying a
sign that does not follow the actual regula tion for the roadway or does not exist at
all in the following cases.
u Regarding the speed limit sign, it may display higher or lower speed than the
actual speed limit.

vehicle type, school zone, etc.
• Figures on the sign are hard to read (e lectric sign, numbers on the sign are
blurred).
