uuWhen DrivinguAdaptive Cruise Control (ACC) with Low Speed Follow (LSF)
*
338Driving
When driving at 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 25 mph (40 km/h): You can set the vehicle speed
only when there is a vehicle detected ahead of you. If the vehicle is moving and the
brake pedal is not depressed, pressing the switch fixes the set speed to 25 mph (40
km/h) regardless of current 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 MID. ■To Set the Vehicle Speed
1Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
*
When the MAIN button is pressed, ACC with LSF and
Lane Keeping Assist System (LKAS) are both turned on
or off.
Do not use ACC with LSF under these conditions:•In poor visibility (e.g., bad weather, such as rain,
fog, and snow).•When you must slow down and speed up
repeatedly.•On winding roads.•When you enter a toll gate, interchange, service
area, parking area, etc. In these areas, there is no
vehicle ahead of you, but ACC with LSF would still
try to accelerate to your set speed.•On a slippery road (for example a road covered
with ice or snow).•When a spare tire
* is installed.
•When going down a steep hill where the engine
braking does not work sufficiently.
When not using ACC with LSF: Turn off adaptive
cruise by pressing the MAIN button. This also will
turn off the Lane Keeping Assist System (LKAS).
1To Set the Vehicle Speed
You can switch the displayed set speed
measurements on the MID between mph and km/h.

uuWhen DrivinguLane Departure Warning (LDW)
*
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.
■How the System Activates
1How the System Activates
LDW may automatically shut off and the LDW
indicator comes and stays on.

Driving
Lane Keeping Assist System (LKAS)
*
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides audible and visual alerts if the vehicle 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 vehicle control. The system does
not work if you take your hands off the steering
wheel or fail to steer the vehicle.
2Multi-Information Display (MID) Warning
and Information Messages P. 96
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.

354Driving
The system can be used when the following conditions are met.
•The lane you are driving in has detectable lane markers on both sides, and your
vehicle is in the center of the lane.
•The vehicle speed is between 45 and 90 mph (72 and 145 km/h).
•You are driving on a straight or slightly curved road.
•The turn signals are off.
•The brake pedal is not depressed.
•The wipers are not in continuous operation.■How to activate the system
1.Press the MAIN button.
uThe LKAS is on in the MID.
The system is ready to use.
2.Press the LKAS button.
uLane outlines appear on the multi-
information display.
The system is activated.■When the System can be Used
1Lane Keeping Assist System (LKAS)
*
•Shadows of adjacent objects are parallel to lane
markings.•The windshield is dirty.•Where the roadway has crossing or other lines
(e.g., such as at an intersection).
1LKAS camera
Never apply a film or attach any objects to the
windshield that could obstruct the LKAS camera’s
field of vision.
Scratches, nicks, and other damage to the windshield
within the LKAS 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 LKAS
camera is necessary for the system to operate properly.
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 LKAS camera.
1When the System can be Used
If the vehicle drifts toward either left or right lane line
due to the system applying torque, turn off the LKAS
and have your vehicle checked by a dealer.

■The system operation is suspended if
you:
•Set the wipers to continuous operation.
uTurning the wipers off resumes the
LKAS.
•Decrease the vehicle speed to 40 mph (64
km/h) or less.
uIncreasing the vehicle speed to 45 mph
(72 km/h) or more resumes the LKAS.
•Depress the brake pedal.
uThe LKAS resumes and starts detecting
the lane lines again once you release the
brake pedal.
■The LKAS may automatically be suspended when:
•The system fails to detect lane lines.
•The steering wheel is quickly turned.
•You fail to steer the vehicle.
•The vehicle is driven on a curved road over the speed limit.
•The camera temperature gets extremely high or low.
Once these conditions no longer exist, the LKAS automatically resumes.When the LKAS is suspended,
the lane lines on the multi-
information display change to
contour lines.
