goes out of the ACC with LSF range.
•Bad weather (rain, fog, snow, etc.)
•When the radar sensor in the front grille gets dirty.
•The vehicle ahead of you cannot be detected.
•An abnormal tire condition is detected, or the tires are skidding.

uuWhen DrivinguForward Collision Warning (FCW)

Driving
Forward Collision Warning (FCW)
*
Alerts you when it detects the possibility of your vehicle colliding with the vehicle in
front of yours.
If the system determines a collision is possible, it gives both visual and audible alerts.
uTake appropriate action to prevent a collision (apply the brakes, change lanes,
etc.).■How the system works
The system may give warnings of potential collisions when your vehicle speed is
above 10 mph (15 km/h).
1Forward Collision Warning (FCW)
*
Important Safety Reminder
FCW cannot detect all objects ahead and may not
detect a given object; accuracy of the system will vary
based on weather, speed and other factors. FCW
does not include a braking function. It is always your
responsibility to safely operate the vehicle and avoid
collisions.
You can change the Forward Collision Warning
Distance setting or turn the system on and off.

1Forward Collision Warning (FCW)
*
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 within 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.
BeepThe camera is located
behind the rearview mirror.
The beeper sounds and the BRAKE message
appears in the MID until a possible collision is
avoided.

■Automatic shutoff
FCW may automatically shut itself off and the FCW indicator comes and stays on
when:
•The temperature inside the system is high.
•The windshield is blocked by dirt, mud, leaves, wet snow, etc.
Once the conditions that caused FCW to shut off improve or are addressed (e.g.,
cleaning), the system comes back on.
1Automatic shutoff
To help reduce the likelihood that high interior
temperatures will cause the camera 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 the camera.
If the Can Not Operate: Camera Too Hot message
appears:•Use the climate control system to cool down the
interior and, if necessary, the defroster mode when
windows are fogged.•Start driving the vehicle to lower the windshield
temperature, which cools down the area around
the FCW camera.

FCW may not activate or may not detect a vehicle in front of your vehicle, and may
activate even when you are aware of a vehicle ahead of you, or when there is no
vehicle ahead, under the following conditions.■FCW Limitations
Condition
●The distance between your vehicle and the vehicle ahead of you is too short.●A vehicle cuts in front of you at a slow speed, and it brakes suddenly.●A vehicle suddenly crosses in front of you.●When either your vehicle or the vehicle ahead of you accelerates rapidly.●The vehicle ahead of you is a motorcycle, a small vehicle, or a unique vehicle such as a tractor.●When you drive off-road or on a mountain road, or curved and winding road for an extended period that makes it difficult for the sensor/camera to
properly detect a vehicle in front of you.●When there are pedestrians or animals in front of your vehicle.●When you drive in bad weather (rain, fog, etc.).●A heavy load in the rear or modifications to the suspension tilts your vehicle.●An abnormal tire condition is detected (wrong tire size, flat tire, etc.).●When the windshield is blocked by dirt, mud, leaves, wet snow, etc.●When the temperature inside the system is high.●A sudden change between light and dark such as an entrance or exit of a tunnel.●You drive into the sunlight (e.g. at dawn or dusk).●When the windshield is dirty or cloudy.●When streetlights are perceived as the taillight of a vehicle in front of yours.●When driving at night, the vehicle ahead of you is running with either taillight bulb burned out.●When you drive in the shadows of trees, buildings, etc.●When your vehicle is towing a trailer.

Driving
Lane Departure Warning (LDW)
*
Alerts you when the system detects a possibility of your vehicle unintentionally
crossing over left or right side lane markings.
If your vehicle is getting too close to detected
left or right side lane markings without a turn
signal activated, LDW will give audible and
visual alerts.
The beeper sounds and the Lane Departure
message appears on the MID, letting you
know that you need to take appropriate
action.
The system begins to search for lane markings when all the following conditions are
met:
•The vehicle is traveling between 40 and 90 mph (64 and 145 km/h).
•The vehicle is on a straight or slightly curved road.
•The turn signals are off.
•The brake pedal is not depressed.■How the System Works
1Lane Departure Warning (LDW)
*
Important Safety Reminder
Like all assistance systems, LDW has limitations.
Over-reliance on LDW may result in a collision. It is
always your responsibility to keep the vehicle within
your driving lane.
LDW only alerts you when lane drift is detected
without a turn signal in use. LDW 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.

■LDW Camera
1LDW Camera
Never apply a film or attach any objects to the
windshield that could obstruct the LDW camera’s
field of vision.
Scratches, nicks, and other damage to the windshield
within the LDW 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 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 LDW
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.
To help reduce the likelihood that high interior
temperatures will cause the camera system to shut off,
when parking, find a shady area or face the front of the
vehicle away from the sun. Also, do not use a reflective
sun shade that can concentrate heat on the camera.
