Quick Reference Guide
Honda Sensing®
Honda Sensing® is a driver support system
which employs the use of two distinctly
different kinds of sensors, a radar sensor
located behind the emblem and a front
sensor camera mounted to the interior side
of the windshield, behind the rearview
mirror.
The camera is
located behind the
rearview mirror.
Front Sensor
Camera
Radar Sensor
The radar sensor
is behind the
emblem.
Adaptive Cruise Control
(ACC) with Low Speed
Follow
(P 391)
Helps maintain a constant vehicle speed and
a set following-interval behind a vehicle
detected ahead of yours and, if the detected
vehicle comes to a stop, can decelerate and
stop your vehicle, wi thout you having to
keep your foot on the brake or the
accelerator.
Road Departure
Mitigation (RDM) System
(P 387)
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.
Lane Keeping Assist
System (LKAS)
(P 408)
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.
Collision Mitigation
Braking System
TM
(CMBS
TM) (P 435)
Can assist you when there is a possibility of
your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The
CMBS
TM is designed to alert you when a
potential collision is determined, as well as
to reduce your vehicle speed to help
minimize collision severity when a collision is
deemed unavoidable.

Adaptive Cruise Control (ACC) with Low Speed
Follow
Helps maintain a constant vehicle speed a nd a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your ve hicle, without yo u having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follow slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.
1 Adaptive Cruise Control (ACC) with Low Speed Follow
Important Reminder
As with any system, there are limits to ACC with Low
Speed Follow. Use the brake pedal whenever
necessary, and always keep a safe interval between
your vehicle and other vehicles.
Be careful not to severely impact the radar sensor
cover.
3WARNING
Improper use of ACC with Low Speed
Follow can lead to a crash.
Use ACC with Low Spee d Follow only when
driving on expressways or freeways and in
good weather conditions.
3WARNING
ACC with Low Speed Follow has limited
braking capability and may not stop your
vehicle in time to avoid a collision with a
vehicle that quickly sto ps in front of you.
Always be prepared to apply the brake
pedal if the conditions require.
When to use
■Vehicle speed for ACC with Low Speed Follow: Desired speed in a range above
roughly 25 mph (40 km/h) ~ 90 mph (145 km/h).
■Gear position for ACC with Low Speed Follow: In (D.
The radar sensor is

The system may automatically shut off and the ACC indicator will come on under
certain conditions. Some examples of th ese conditions are listed below. Other
conditions may reduce some of the ACC functions.
2 Front Sensor Camera P. 385
■Environmental conditions
Driving in bad weather (r ain, fog, snow, etc.).
■Roadway conditions
Driving on a snowy or wet roadway (obscure d lane marking, vehicle tracks, reflected
lights, road spray, high contrast).
■Vehicle conditions

■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.
• When 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.
• When there are animals in front of your vehicle.
• When 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.
• When driving through a narrow iron bridge.
• When the vehicle ahead of you brakes suddenly.
• When the vehicle ahead of you has a unique shape.
• When your vehicle or the vehicle ahead of you is driving on one edge of the lane.1ACC with Low Speed Follow Conditions and Limitations
Have your vehicle checked by an authorized Honda
Clarity Fuel Cell dealer if you find any unusual
behavior of the system (e.g., the warning message
appears too frequently).
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehicle checked by an authorized
Honda Clarity Fuel Cell dealer:
•The vehicle mounted onto a bump, curb, chock,
embankment, etc.
•You drive the vehicle where the water is deep.
•Your vehicle has a frontal collision.

■Automatic cancellation
The beeper sounds and a message appears on the driver information interface and
the head-up display when ACC with Low Sp eed Follow is automatically canceled.
Any of these conditions may cause the ACC with Low Speed Follow to automatically
cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the front grille gets dirty.
• 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 ACC with Low Speed Follow range is too
close to your vehicle.
• When a detected vehicle goe s out of the ACC with Low Speed Follow range while
your vehicle is stationary.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with Low Speed Follow automatic ca ncellation can be also triggered by the
following causes. In these cases, the pa rking brake will be automatically applied.
• The driver’s seat belt is unfasten ed when the vehicle is stationary.
• The vehicle stops for mo re than 10 minutes.
• The power system is turned off.
1Automatic cancellation
