Traffic Sign Recognition System

Continued

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 rearview 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

Traffic Sign Recognition System

Not all signs may be displayed, 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 for the road conditions.

Never apply a film or attach any objects to the
windshield that could obstruct the camera’s field of
vision and cause the system to operate abnormally.
Scratches, nicks, and other damage to the windshield
within the camera’s field of vision can cause the
system to operate abnormally. If this occurs, we
recommend that you replace the windshield with a
genuine Honda replacement windshield. Making
even minor repairs within the camera’s field of vision
or installing an aftermarket replacement windshield
may also cause the system to operate abnormally.
After replacing the windshield, have a dealer
recalibrate the camera. Proper calibration of the
camera is necessary for the system to operate
properly.

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.

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 cools 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 windshield and driven for a
while, have your vehicle checked by a dealer.

Front Sensor Camera

The camera, used in systems such as LKAS, RDM, ACC with LSF, CMBS

, 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 reflective sun shade, do
not allow it to cover the camera housing.
