uuHonda Sensing ®u Lane Keeping Assist System (LKAS)
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 ve hicle 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 an
autonomous driving system and always requires
driver attention and control. The system does not
work if you take your hands off the steering wheel or
fail to steer the vehicle.
The LKAS is convenient when it is used on
expressways or freeways.
Do not place objects on the instrument panel.
Objects may reflect on th e 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.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 396
The LKAS may not work properly or may work
improperly under the certain conditions: 2 LKAS Conditions and Limitations P. 369
When you operate the turn signals to chan ge 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.

uuHonda Sensing ®u Traffic Jam Assist
Continued
Driving
Traffic Jam Assist
The Traffic Jam Assist system uses a camera mounted to the upper portion of the
windshield to detect and monitor left and right white (or yellow) traffic lane lines.
Based on inputs from the camera, the system can apply steering torque to keep your
vehicle in the center of the detected lane.
■How Traffic Jam Assist works
When you are in heavy traffic and Lane Keep ing Assist System (LKAS) is active, the
Traffic Jam Assist system, upon detecting th e traffic lane lines, will apply steering
torque to help keep your vehicle in the center of the lane.
When the driver takes full control of the steering, the steering assist function is
temporarily canceled.
The torque applied to the steering may not be noticeable when the driver has full
control of the steering, or when the surface of the road is rough or uneven.
1 Traffic Jam Assist
Important Safety Reminders
Traffic Jam Assist is for your convenience only. It is
not an autonomous driving system and always
requires driver at tention and control. The system
does not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
Traffic Jam Assist is conven ient when it is used on
expressways or freeways.
You can read about handling information for the

The Traffic Jam Assist only alerts you when lane drift
is detected without a turn signal in use. The Traffic
Jam Assist may not detect all lane markings or lane
departures; accuracy will vary based on weather,

It is always your responsibility to safely operate the
vehicle and avoid collisions.
Traffic Jam Assist may not work properly under
certain conditions: 2 Traffic Jam Assist: Conditions and
Limitations P. 378

When you use the turn signal to indica te a lane change, Traffic Jam Assist is
temporarily deactivated. It is reactivated once the vehicle is traveling in the
center of the lane and the system has detected the traffic lane lines.

uuHonda Sensing ®u Road Departure Mitigation System
Driving
Road Departure Mitigation System
Alerts and helps assist you when the syst em detects a possibility of your vehicle
crossing over detected lane markings, or approaching the outer edge of the
pavement (into grass or gravel border) or a detected oncoming vehicle.
The front sensor camera behind the rearview
mirror monitors left and right lane markings in
white or yellow, the outer edge of the
pavement (bordered by grass or gravel) or a
detected oncoming vehicles.
If your vehicle approaches any detected lane
markings, the outer edge of the pavement
(bordered by grass or gravel) or a detected
oncoming vehicles when the turn signals have
not been engaged, the system activates.u If the system cannot de tect lane markings
(in white or yellow), no assistance will be
provided to avoid approaching oncoming
vehicles. In addition to a visual alert, the
system assists with steering and alerts you
with rapid steering wheel vibrations to
help you remain within the detected lane.
2 Vehicle Settings P. 126
As a visual alert, the Lane departure
message appears on the driver information
interface.
■How the System Works
1 Road Departure Mitigation System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Overreliance on the Road Departure Mitigation
system may result in a collision. It is always your
responsibility to keep the vehicle within your driving
lane.
The Road Departure Mitiga tion system alerts you
when the system detects that you are approaching
the outer edge of the paveme nt (into grass or gravel
border), an oncoming vehicle, or drifting into another
lane without using a turn signal.
The Road Departure Mitigation system may not detect
all lane markings or ever y instance of lane drift.
The Road Departure Miti gation system may not
detect that you are approa ching the outer edge of
the pavement (bordered by grass or gravel) or an
oncoming vehicle.
The Road Departure Mitiga tion system may not be
able to assist you depend ing on weather, speed or
road conditions.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 396

such as the units displayed on the traffic sign as well
as the speed and direction of travel of the vehicle. In
some cases, the system may display false warnings or
other inaccurate information. 2 Traffic Sign Recognition System Conditions

The unit for speed limits (mph or km/h) varies from
country to country. Just after entering a country
whose unit differs to the one of the country from
which you came, the Traffic Sign Recognition system

uuHonda Sensing ®u Front Sensor Camera
Driving
Front Sensor Camera
The camera, used in systems such as La ne Keeping Assist System (LKAS), Road
Departure Mitigation system, Adaptive Cruise Control (ACC) with Low Speed
Follow, Collision Mitigation Braking System
TM (CMBSTM), Traffic Jam Assist, and
Traffic Sign Recognition system is designed to detect an object that triggers any of
the systems to operate their 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 th e front grille that could
obstruct the camera’s fiel d of vision and cause the
system to operate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s fiel d of vision can cause the
system to operate abnormall y. If this occurs, we
recommend that you replac e the windshield with a
genuine Honda replacem ent windshield. Making
even minor repairs within th e camera’s field of vision
or installing an aftermarket replacement windshield
may also cause the system to operate abnormally.
After replacing the winds hield, have a dealer
recalibrate the camera. Pr oper 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.
