uuWhen Driving uLane Departure Warning (LDW)
Continued
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 la ne markings when all the following conditions are met:
• The vehicle is traveling between 40-90 mph (64-145 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.

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 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 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 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.
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 /CAN
NOT OPERATE 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 LDW camera.

*
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. 93
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.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly under the following
conditions:•Your tires are over or under inflated.•Your tires or wheels are of varied size or
construction.•Your vehicle’s suspension has been altered,
changing the height of the vehicle.•Your vehicle has heavy load in the trunk or on the
rear seats.•A compact spare tire
* is mounted.
•Driving on snowy or wet roads.•Roadway lane markers are difficult to see due to
weather (rain, snow, fog, etc.) or road conditions.•Driving on a road with temporary lane markings.•Multiple or varied lane markings are visible on the
pavement due to road repairs or old lane markings.•Roadway objects or structures are misinterpreted
as lane markers.•On non-freeway roadways and on freeways with
many curves.
■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.
■Audible and visual alerts
Beeps and a warning display alert
you that the vehicle is drifting out of
a detected lane.
When you operate the turn signals to change 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.

reliance on BSI may result in a collision.
The system is for your convenience only. Even if an
object is within the alert zone, the following
situations may occur.•The BSI alert indi cator may not come on due to
obstruction (splashes, etc.) even without the Blind
Spot Not Available multi-information display
appearing.•The BSI alert indicator may come on even with the
message appearing.
The BSI alert indicator may not come on under the
following conditions:•A vehicle does not stay in the alert zone for more
than two seconds.•A vehicle is parked in a side lane.•The speed difference between your vehicle and the
vehicle you are passing is greater than 6 mph (10
km/h).•An object not detected by the radar sensors
approaches or passes your vehicle.
