uuHonda Sensing ®u Adaptive Cruise Control (ACC) with Low Speed Follow
Continued
Driving
■Detection limitations
• A vehicle suddenly crosses in front of you.
• The interval between your vehicle and the vehicle ahead of you is too short.
• A vehicle cuts in front of you at a slow speed, and it brakes suddenly.
• You accelerate rapidly and approach the vehicle ahead of you at high speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter, or other small
vehicle.
• There are animals in front of your vehicle.
• You drive on a curved or winding or undulating road that makes it difficult for the
sensor to properly detect a vehicle in front of you.
• The speed difference between your vehi cle and a vehicle in front of you is
significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Your vehicle abruptly crosses over in front of an oncoming vehicle.

uuHonda Sensing ®u Adaptive Cruise Control (ACC) with Low Speed Follow
Driving
■Automatic cancellation
The beeper sounds and a message appears on the driver information interface when
ACC with Low Speed Follow is automatically canceled. Any of these conditions may
cause the ACC with Low Speed Fo llow to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor at the lower part of the front bumper gets dirty.
• The vehicle ahead of yo u cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the AC C with Low Speed Follow range is too
close to your vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• When the Maximum Load Limit is exceeded.
• When passing through an enclosed space, such as tunnel.
• The vehicle has repeatedly applied the brakes to maintain the set speed (for
example, you are descending a long slope).
The ACC with Low Speed Follow automatic ca ncellation can be also triggered by the
following causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastene d when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The engine is turned off.
1Automatic cancellation
Even though ACC with Low Speed Follow has been
automatically canceled, you can still resume the prior
set speed. Wait until the condition that caused ACC
with Low Speed Follow to cancel improves, then
press the SET/– button.

uuHonda Sensing ®u Road Departure Mitigation (RDM) System
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 steering torque and alerts
you with rapid vibrations on the steering
wheel, to help you remain within the detected
lane.
2 Customized Features P. 352
As a visual alert, the Lane Departure
message appears on the driver information
interface.
If the system determines that its steering i nput 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 (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. 2 Front Sensor Camera P. 506
The RDM system may not wo rk properly or may work
improperly under the certain conditions: 2 RDM Conditions and Limitations P. 498
There are times when you may not notice RDM
functions due to your opera tion of the vehicle, or
road surface conditions.
In the following case, a beeper sounds, a message
related to the ACC with Low Speed Follow 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).
