Never apply a film or attach any objects to the
windshield that could obstruct the FCW camera’s
field of vision.
Scratches, nicks, and other damage to the windshield
within the FCW 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 withi n 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 FCW
camera is necessary for the system to operate
properly.
Beep The camera is located
behind the rearview mirror.
The beeper sounds and the BRAKE message
appears in the MID until a possible collision is
avoided.
