Front Sensor Camera
*
The camera, used in systems such as LDW, FCW with Pedestrian Detection, LKAS,
RDM, ACC with LSF, and CMBS
TM, is designed to detect an object that triggers any
of the systems to operate its functions.
This camera is located behind the rearview
mirror.

temperatures will cause the camera’s sensing

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
1Front Sensor Camera
*
Never apply a film or attach any objects to the
windshield that could obstruct the camera’s field of
vision.
Scratches, nicks, and other damage to the windshield
within the ca mera’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
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 air flow directed towards the camera.•Start driving the vehicle to lower the windshield
temperature, which cools down the area around
the camera.

354Driving
When driving at about 25 mph (40 km/h) or above: Take your foot off the
pedal and press down the RES/+/SET/– switch when you reach the desired speed.
The moment you release the switch, the set speed is fixed, and ACC with LSF begins.
When driving at slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pressing the switch fixes the set speed to
about 25 mph (40 km/h) regardless of cu rrent vehicle speed. If the vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed. When ACC with LSF starts operating, the
vehicle icon, distance bars and set speed
appear on the multi-information display. ■

Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicle control. The system does
not work if you take your hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and
Information Messages P. 113
LKAS only alerts you when lane drift is detected
without a turn signal in use. LKAS may not detect all
lane markings or lane departures; accuracy will vary
based on weather, speed, and lane marker condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly or may work
improperly under the certain conditions: 2 LKAS Conditions and Limitations P. 384
