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 in the front grille 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

The radar sensor 
is behind the

Adaptive Cruise Control 
(ACC) with Low Speed 
Follow (LSF) 
(P 389)
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, without you having to 
keep your foot on the brake or the 
accelerator.
Road Departure 
Mitigation (RDM) System 
(P 385)
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 404)
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 428)
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 vehi cle speed to help 
minimize collision severity when a collision is 
deemed unavoidable.

1. Remove the center shoulder belt from the 
guide.
2. Pull the release lever in  the trunk to release 
the lock.
3. Fold the seat-back down.
■60/40 Split Folding Down the Rear Seats160/40 Split Folding Down the Rear Seats
The rear seat-back(s) can be folded down to 
accommodate bulkier items in the trunk.
To lock the seat-back upri ght, push it backwards until 
it locks.
When returning a seat-back to its original position, 
push it firmly back. Also, m ake sure all rear shoulder 
belts are positioned in front  of the seat-back, and the 
center shoulder belt is re -positioned in the guide.
Make sure that the folded seat-back does not press 
against the front passenger se at, as this can cause the 
weight sensors in the front  passenger seat to work 
improperly.

Also make sure all items in the trunk or items 
extending through the opening into the rear 
seats are properly secured. Loose items can fly 
forward if you have to brake hard.
The front seat(s) must be  far enough forward so they 
do not interfere with the rear seats as they fold 
down.

Adaptive Cruise Control (ACC) with Low Speed 
Follow (LSF)
Helps maintain a constant vehicle speed an d 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 you having to keep your foot on the brake or the 
accelerator.
When ACC with LSF slows your vehicle by  applying the brakes, your vehicle's brake 
lights will illuminate.
1 Adaptive Cruise Control (ACC)  with Low Speed Follow (LSF)
Important Reminder
As with any system, there are limits to ACC with LSF. 
Use the brake pedal whenever necessary, and always 
keep a safe interval betw een your vehicle and other 
vehicles.
Be careful not to severely  impact the radar sensor 
cover.
3WARNING
Improper use of ACC wi th LSF can lead to a 
crash.
Use ACC with LSF only when driving on 
expressways or freeways and in good 
weather conditions.
3WARNING
ACC with LSF has limite d braking capability 
and may not stop your vehicle in time to 
avoid a collision with a vehicle that quickly 
stops in front of you.
Always be prepared to apply the brake 
pedal if the conditions require.
When to use
■Vehicle speed for ACC with LSF: A vehicle is detected ahead within ACC with LSF 
range – ACC with LSF operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with LSF range – ACC with LSF operates at the 
speed of 25 mph (40 km/h) or above.
■Gear position for ACC with LSF: In ( D. The radar sensor is 
behind the emblem.
The camera is 
located behind 
the rearview 
mirror.

Driving
The system may automatically shut off and the  ACC indicator will come on under 
certain conditions. Some examples of these conditions  are listed below. Other 
conditions may reduce some of the ACC functions.
2 Front Sensor Camera  P. 383
■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 spra y, high contrast).
■Vehicle conditions
• The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.
• An abnormal tire or wheel condition (Wrong sized, varied size or construction, 
improperly inflated tire, etc.).
• The camera temperature gets too high.
• The parking brake is applied.
• When the front grille is dirty.
• The vehicle is tilted due to a heavy load or  suspension modifications.
• When tire chains are installed.
■ACC with LSF Conditions and Limitations1ACC with LSF Conditions and Limitations
The radar sensor for ACC with LSF is shared with the 
collision mitigation braking system
TM (CMBSTM).
2 Collision Mitigation Braking SystemTM 
(CMBSTM)  P. 428
You can read about handling information for the 
camera equipped with this system. 2 Front Sensor Camera  P. 383
Always keep the radar sensor cover clean.
Never use chemical solvents or polishing powder for 
cleaning the sensor cover.  Clean it with water or a 
mild detergent.
Do not put a sticker on the radar sensor cover or 
replace the radar sensor cover.
If you need the radar sensor to be repaired, or 
removed, or the radar se nsor cover is strongly 
impacted, turn off the system by pressing the MAIN  
button and take your vehicl e to an authorized Honda 
Clarity Electric dealer.
Have your vehicle checked  by an authorized Honda 
Clarity Electric dealer if  you find any unusual behavior 
of the system (e.g., the wa rning message appears too 
frequently).

■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 vehicl e 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 LSF Conditions and Limitations
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 Electric 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 ca ncellation
The beeper sounds and a message appears on the driver information interface when 
ACC with LSF is automatically canceled.  Any of these conditions may cause the ACC 
with LSF 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 AC C with LSF range is too close to your 
vehicle.
• The camera behind the rearview mirror, or the area around the camera, including 
the windshield, gets dirty.
The ACC with LSF automatic cancellation ca n 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 power system is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically 
canceled, you can still resu me the prior set speed. 
Wait until the condition that caused ACC with LSF to 
cancel improves, then press the  RES/+ button.
