uuBefore Driving uDriving Preparation
Driving
• Be sure items placed on the floor behind the front seats cannot roll under the
seats.
u They can interfere with the driver’s ability to operate the pedals, the operation
of the seats, or the operation of the sensors under the seats.
• Everyone in the vehicle must fasten their seat belt.
2Fastening a Seat Belt P. 51
•Make sure that the indicators in the in strument panel come on when you start the
vehicle, and go off soon after.
u Always have an authorized Honda Clarity Fuel Cell dealer check the vehicle if a
problem is indicated.

Driving
Front Sensor Camera
The camera, used in systems such as LK AS, RDM, ACC with Low Speed Follow, and
CMBSTM, is designed to detect an object that triggers any of the systems to operate
its 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, hood, or front grille that could obstruct
the camera’s field 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 th e windshield, have an authorized
Honda Clarity Fuel Cell deal er recalibrate the camera.
Proper calibrat ion of the camera is necessary for the
system to ope rate 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.

If the Some Driver Assist Systems Cannot
Operate: Camera Temperature Too High message
appears:
•Use the climate control system to cool down the
interior and, if necessary, also use defroster mode
with the airflow directed towards the camera.
•Start driving the vehicle to lower the windshield
temperature, which cool s down the area around
the camera.
If the Some Driver Assist Systems Cannot
Operate: Clean Front Windshield message
appears:
•Park your vehicle in a sa fe place, and clean the
windshield. If the message does not disappear after
you have cleaned the winds hield and driven for a
while, have your vehicle checked by an authorized
Honda Clarity Fuel Cell dealer.

uuWhen Driving uRoad Departure Mitigation (RDM) System
Continued
Driving
Road Departure Mitigation (RDM) System
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.
The front camera behind the rearview mirror
monitors left and right lane markings (in white
or yellow). If your vehicl e 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. 300
As a visual alert, the Lane Departure
message appears on the driver information
interface.
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 with out 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. 383
The RDM system may not wo rk properly or may work
improperly under the certain conditions: 2 RDM Conditions and Limitations P. 387
There are times when you may not notice RDM
functions due to your opera tion of the vehicle, or
road surface conditions.

Continued
Driving
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.

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 Fuel Cell dealer.
