562 uu Honda 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 recogniz ed 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 1 Traffic 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.Driver information interface Head-up display *

If the system does not detect any traffic signs while you are driving, the image below
may appear. 1 Traffic 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 de froster 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.Driver information interface Head-up display *

Driving Front Sensor Camera The camera, used in system s such as LKAS, RDM, ACC *
, ACC with LSF *
, CMBS TM

and traffic sign recognition system, 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 re flective 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 detect ing lane lines properly.Front Sensor
