Driving
Traffic Sign Recognition System
Reminds you of road sign information of the current speed limit, your vehicle has
just passed through, showing it on the gauge and the head-up display*.
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, 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 field of vision can cause the
system to operate abnormally. If this occurs, we
recommend that you replace the windshield with a
genuine Acura replacement windshield. Making even
minor repairs within the ca mera’s field of vision or
installing an aftermarket replacement windshield may
also cause the system to operate abnormally. After
replacing the windshi eld, 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.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 547

uuAcuraWatchTMuTraffic Sign Recognition System
542
Driving
Shows the current speed limit based on either information compiled through the
navigation system* or speed limit signs captured by the front sensor camera. 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.
If the system does not detect any traffic signs while you are driving, the sign icon will
not be displayed.
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 Works1Traffic Sign Recognition System
You can select whether the source of the speed limit
information is the front sensor camera or the
navigation system.
You can also turn off speed limit information. 2 Customized Features P. 345

road, etc.).
• There are things that look similar to th e color or shape of the recognition object
(similar sign, electric sign, signboard, structure, etc.).

uuAcuraWatchTMuFront Sensor Camera
Continued
Driving
Front Sensor Camera
The camera, used in systems such as LKAS, Road Departure Mitigation, ACC with
Low Speed Follow, CMBSTM, and Traffic Jam Assist is de signed 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 Acura replacement windshield. Making even
minor repairs within the ca mera’s field of vision or
installing an aftermarke t 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.
