Driving
■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 di rt, 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.
1 Automatic shutoff
To help reduce the likelihood that high interior
temperatures will cause the ca mera 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 cool s down the area around
the FCW camera.
The camera is located
behind the rearview mirror.
Beep
The beeper sounds and the BRAKE
message appears in the multi-
information display until a possible
collision is avoided.

uuWhen Driving uLane Departure Warning (LDW)
Driving
Lane Departure Warning (LDW)
Alerts you when the system detects a possibility of your vehicle unintentionally
crossing over detected 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 multi-information
display, letting you know that you need to
take appropriate action.
The system begins to search for lane mark ings when all the following conditions are
met:
• The vehicle is traveling between 45 and 90 mph (72 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 respons ibility to keep the vehicle within
your driving lane.
LDW only alerts you when lane drift is detected
without a turn signal in us e. LDW may not detect all
lane markings or lane departures; a ccuracy will vary
based on weather, speed and lane marker condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.

Driving
The camera is located behind the rearview
mirror.
■Lane Departure Warning Camera (LDW Camera)1Lane Departure Warning Camera (LDW Camera)
Never apply a film or attach any objects to the
windshield that could obs truct the LDW camera’s
field of vision.
Scratches, nicks, and othe r damage to the windshield
within the LDW camera’s fi eld 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. Prop er calibration of the LDW
camera is necessary for the system to operate
properly.

Driving
Lane Keeping Assist System (LKAS)*
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides tactile and visual alerts if the ve hicle is detected drifting out of its lane.1Lane Keeping Assist System (LKAS)*
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicl e control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and
Information Messages P. 95
Do not place objects on the instrument panel.
Objects may reflect on th e front windshield and
prevent correct detectio n of the traffic lanes.
The LKAS only alerts you when lane drift is detected
without a turn signal in us e. The 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. 391
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
* P. 359
When you operate the turn signals to chan ge lanes, the system is suspended, and
resumes after the signals are off.
() If you make a lane change without operating the turn signals, the LKAS
alerts activate, and torque is applied to the steering.
■LKAS camera
Monitors the lane
lines
■Tactile and visual alerts
Rapid vibrations on the steering wheel and a warning display alert you that the
vehicle is drifting out of a detected lane.
■Steering input assist
The system applies torque to the
steering to keep the vehicle between
the left and right lane lines. The applied
torque becomes stronger as the vehicle
gets closer to either of the lane lines.
