uuHonda Sensing ®u Lane Keeping Assist System (LKAS)
Driving
■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.
• Driving through a sharp curve.
• Driving at a speed in excess of approximately 90 mph (145 km/h).
Once these conditions no longer exis t, the LKAS automatically resumes.
■The LKAS may automatically be canceled when:
• The camera temperature gets extremely high or low.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• The ABS or VSA ® system engages.
The beeper sounds if the LKAS is automatically canceled.

Driving
The system may not detect lane markings and therefore may not keep the vehicle in
the middle of a lane under certain conditions, including the following:
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between lane lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.

■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on a road with temporary lane markings.
• Faint, multiple, or varied lane markings are visible on the roadway due to road
repairs or old lane markings.
• The roadway has merging, split, or crossing lines (e.g., such as at an intersection
or crosswalk).
• The lane markings are extremely narrow, wide, or changing.
• The vehicle in front of you is driving near the lane lines.
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving on rough or unpaved roads, or over bumpy surfaces.

lines (or yellow lines).
• Driving on roads with double lines.
■Vehicle conditions
• Headlight lenses are dirty or the h eadlights are not properly adjusted.
• The outside of the windshield is streaked or blocked by dirt, mud, leaves, wet
snow, etc.
• The inside of the windshield is fogged.
• The camera temperature gets too high.
• An abnormal tire or wheel condition (wrong size, varied size or construction,
improperly inflated, co mpact spare tire, etc.).

uuHonda Sensing ®u Road Departure Mitigation System
Driving
Road Departure Mitigation 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 steering torque and alerts you with
rapid vibrations on the steering wheel, to help
you remain within the detected lane.
2 Customized Features P. 298
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 wh en 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 System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Over-reliance 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 Mitigation system only alerts you
when lane drift is detected without a turn signal in
use. The Road Departure Mitigation system may not
detect all lane markings or lane or roadway
departures; accuracy will vary based on weather,
speed and lane marker condi tion. It is always your
responsibility to sa fely operate the vehicle and avoid
collisions.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 465
The Road Departure Mitigati on system may not work
properly or may work im properly under the certain
conditions: 2 Road Departure Mitigation system
Conditions and Limitations P. 463
There are times when you may not notice Road
Departure Mitigation system functions due to your
operation of the vehicle, or road surface conditions.

The system becomes ready to start sear ching for lane markings when all the
following conditions are met:
• The vehicle is traveling between about 45 and 90 mph (72 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.
• The wipers are not in continuous operation.
• The vehicle is not accelera ting or braking, and the steering wheel is not being
turned.
• The system makes a determination that th e driver is not actively accelerating,
braking or steering.
