Driving
Road Departure Mitigation (RDM) System
Alerts and helps to assist you when the sy stem detects a possibility of your vehicle
unintentionally crossing over detected la ne markings and/or leaving the roadway
altogether.
The front camera behind the rearview mirror
monitors left and right lane markings (in white
or yellow). If your vehicle is getting too close
to detected lane markings without a turn
signal activated, the system, in addition to a
visual alert, applies st eering torque and alerts
you with rapid vibrations on the steering
wheel, to help you remain within the detected
lane.
2 Customized Features P. 295
As a visual alert, the Lane Departure
message appears on the multi-information
display.
If the system determines that its steering input
is insufficient to keep your vehicle on the
roadway, it may apply braking. u Braking is applied only when the lane
markings are solid continuous lines.
■How the System Works
1Road Departure Mitigation (RDM) System
Important Safety Reminder
Like all assistance systems, the RDM system has
limitations.
Over-reliance on the RDM system may result in a
collision. It is always your responsibility to keep the
vehicle within your driving lane.
The RDM system only alerts you when lane drift is
detected without a turn signal in use. The RDM
system may not detect all la ne markings or lane or
roadway departures; accu racy will vary based on
weather, speed and lane marker condition. It is
always your responsibilit y to safely operate the
vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system.

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 al erts 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 y our hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and
Information Messages P. 94
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 use. 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 an d 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. 426
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 400
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 operat ing the turn signals, the LKAS alerts
activate, and torque is applied to the steering.

■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.

Driving
Provides assistance to keep the vehicle in the center of the lane. When the vehicle
nears a white or yellow line, steering force of the electric power steering will become
stronger.
When the vehicle enters the warning area, the LKAS alerts you with slight steering
wheel vibration as well as a warning display.
■Lane Keep Support Function1 Lane Keeping Assist System (LKAS)
The LKAS may not function as designed while driving
in frequent stop and go traf fic, or on roads with
sharp curves.
When it fails to detect lanes, the system will
temporarily be canceled. When lane is detected,
system will recover automatically.

Driving
Traffic Jam Assist is activated when a ll of the following circumstances exist:
• LKAS is activate.
• ACC with Low Speed Fo llow is active.
• The vehicle speed is between 0 and 45mph (0 and 72km/h) and there is a vehicle
detected traveling ahead.
• The lane in which you are driving has dete ctable lane markers on both sides, and
your vehicle is in the center of the lane.
• You are driving on a straight or slightly curved road.
• The driver is gripping the steering wheel.
Do not use Traffic Jam Assist in any of the following situations:
• You are traveling on a ro ad with sharp curves.
u The system may not allow your vehicle to respond in a manner best suited for
the road conditions.
• You are entering a toll booth, interchange, service area, or parking area.
u If the vehicle ahead disappears from th e travel path of your vehicle, your
vehicle may suddenly accelerate to resume the set speed.
• You are driving in adverse weat her (rain, fog, snow, etc.).
u The system may not be able to correctly determine the interval between your
vehicle and the one ahead.
• The surface of the road is slippery, for ex ample, it is icy or covered with snow.
u The tires may slip, causing you to lose control of the vehicle.
• You are driving in a HOV lane and motorcycles are passing you to the side, or you
are required to keep your vehicle to the right or the left of the lane.
u The system may not be able to co rrectly determine the vehicle ahead.

uuWhen Driving uTraffic Jam Assist
Driving
■When a vehicle is traveling ahead
When a vehicle ahead of yours is detected entering the Traffic Jam Assist detection
area, Traffic Jam Assist adjusts the speed of your vehicle to maintain the selected
interval between your vehicle and the one ah ead. It also applies steering torque to
keep your vehicle in the ce nter of the detected lane.
Keep your vehicle near the center of the lane
while driving.u Traffic Jam Assist will be activated once
the camera has detected the white
(yellow) traffic lane lines on either side of
the lane and the radar sensor and
camera have detected a vehicle driving
ahead.
The dotted outer lines change to solid
ones and a vehicle icon appears on the
multi-information display.
■How Traffic Jam Assist Works1How Traffic Jam Assist Works
If your vehicle veers too far to the right or the left of
the white (yellow) traffic lane lines while Traffic Jam
Assist is active, deactivate Traffic Jam Assist and have
an authorized Acura deal er inspect your vehicle.
In some cases the system cannot properly detect the
traffic lane lines and, as a result, will not provide
steering assistance. 2 Traffic Jam Assist: Conditions and
limitations P. 434
If the driver takes his or her hands off the steering
wheel or does not adequate ly maintain control of
steering, the warning below will appear.
If the driver does not grip the steering wheel after the
warning above has repeatedly appeared, a warning
buzzer will sound and Traffi c Jam Assist will be
canceled.
You can have the head-up display show you the
current state of Traffic Jam Assist. 2 Head-Up Display P. 119

uuWhen Driving uTraffic Jam Assist
Driving
To cancel Traffic Jam Assist, you can do any of the following:
• Press the MAIN button.
• Press the LKAS button.
• When the ACC with Low Speed Follow is deactivated.
■When Traffic Jam Assist may au tomatically be suspended when:
The system is temporarily canceled auto matically under the following circumstances.
• The system fails to detect lane lines.
• The vehicle ahead of yo u cannot be detected.
• The steering wheel is turned quickly.
• You fail to steer the vehicle.
• The vehicle in front of you is driving near the lane lines.
• The wipers are set to high.
• The interval between your vehicle and the one traveling ahead is over 197 feet
(60m).
Once these conditions no longer exist, th e Traffic Jam Assist automatically resumes.
■Canceling Traffic Jam Assist1How Traffic Jam Assist Works
If you are traveling slower than the vehicle detected
ahead or a vehicle that is de tected cutting in front of
you and the interval betw een your vehicle and the
detected vehicle gradually increases, your vehicle will
continue to follow that ve hicle without emitting any
warning, even if the interv al between the vehicle is
minimal.
1 When Traffic Jam Assist may automatically be suspended when:
You are traveling over 45mph (72km/h).
u When the speed of the vehicle reaches 45mph
(72km/h), Traffic Jam Assist is deactivated and LKAS
is activated instead. Once the speed of the vehicle
drops to under 42mph (68km/ h), Traffic Jam Assist
is reactivated.
