uuAcuraWatchTMuTraffic Sign Recognition System
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 multi-information display and the head-up
display
*.
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.
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 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.
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.
