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.

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 Driver Information Interface Warning and

Information Messages P. 108

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. 524

■

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.

Honda Sensing®

Road Departure Mitigation (RDM) System

Continued

Driving

Road Departure Mitigation (RDM) System

Alerts and helps to assist you when the system determines 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. 367, 378

As a visual alert, the Lane Departure
message appears on the driver information
interface.

If the system determines that its steering input is insufficient to keep your vehicle on
the roadway, it may apply braking.

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

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.

2 Front Sensor Camera P. 537

The RDM system may not work properly or may work
improperly under the certain conditions:

2 RDM Conditions and Limitations P. 529

There are times when you may not notice RDM
functions due to your operation of the vehicle, or
road surface conditions.

In the following case, a beeper sounds, a message
related to the ACC with LSF appears on the driver
information interface, and the braking function
controlled by the RDM system is canceled.

•

The vehicle has repeatedly applied the brakes to
maintain the set speed (for example, you are
descending a long slope).
