Lane Keeping Assist System (LKAS)

Continued

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 vehicle is detected drifting out of its lane.

1

Lane 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.

2 Multi-Information Display Warning and

Information Messages P. 97

Do not place objects on the instrument panel.
Objects may reflect on the windshield and prevent
correct detection 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 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. 476

You can read about handling information for the
camera equipped with this system.

2 Front Sensor Camera P. 483

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.

■

Front Sensor 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.

Road Departure Mitigation (RDM) System

Continued

Driving

Road Departure Mitigation (RDM) System

Alerts and helps to assist you when the system detects a possibility of your vehicle
unintentionally crossing over detected lane 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 steering torque and alerts
you with rapid vibrations on the steering
wheel, to help you remain within the detected
lane.

2 Customized Features P. 332

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.

The system cancels assisting operations when you turn the steering wheel to avoid
crossing over detected lane markings.

If the system operates several times without detecting driver response, the system
beeps to alert you.

How the System Works

1

Road 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 lane markings or lane or
roadway 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.

You can read about handling information for the
camera equipped with this system.

Front Sensor Camera

Continued

Driving

Front Sensor Camera

The camera, used in systems such as LKAS, RDM, ACC with LSF, and CMBS

TM

, is

designed to detect an object that triggers any of the systems to operate its
functions.

This camera is located behind the rearview
mirror.

To help reduce the likelihood that high interior
temperatures will cause the camera’s sensing
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
it.

■

Camera Location and Handling Tips

1

Front Sensor Camera

Never apply a film or attach any objects to the
windshield, the hood, or the front grille that could
obstruct the camera’s field of vision and cause the
system to operate abnormally.
Scratches, nicks, and other damage to the windshield
within the 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
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.
