The traffic sign recognition system may not operate correctly, such as displaying a
sign that does not follow the actual regulation for the roadway or does not exist at

uuAcuraWatchTMuFront Sensor Camera
Driving
Front Sensor Camera
The camera, used in systems such as LKAS, RDM, ACC with Low Speed Follow,
CMBSTM, Traffic Sign Recognition System, an d Traffic Jam Assist 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.
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.

If the Some Driver Assist Systems Cannot
Operate: Camera Temperature Too High message
appears:
•Use the climate control system to cool down the
interior and, if necessary, also use defroster mode
with the airflow 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:
•Park your vehicle in a sa fe 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.
