Driving ■ Automatic cancellation
The beeper sounds and a message appears on the driver information interface when
ACC with LSF is automatically canceled. An y 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 ACC 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 can be also triggered by the following
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfasten ed when the vehicl e is stationary.
• The vehicle stops for mo re than 10 minutes.
• The power system is turned off.
In the following cases, a buzzer sounds, ACC with LSF is deactivated, and the
message Cruise Cancelled: Slope Too Steep. Watch Downhill Speed appears in
the driver information interface.
• While descending a long slope and the vehi cle has repeatedly applied the brakes
to maintain the set speed. 1 Automatic 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.18 CLARITY PHEV CSS-31TRW6000.book 412 ページ ２０１７年８月３１日　木曜日　午後２時４９分

Driving
Lane Keeping Assist System (LKAS) Provides steering input to help keep the vehicle in the middle of a detected lane and
provides tactile and visual al erts if the vehicle is detected drifting out of its lane. 1 Lane Keeping Assist System (LKAS)
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicl e control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
2 Driver Information Interface Warning and
Information Messages P. 119
Do not place objects on the instrument panel.
Objects may reflect on th e front windshield and
prevent correct detectio n of the traffic lanes.
The LKAS only alerts you wh en lane drift is detected
without a turn signal in us e. The LKAS may not detect
all lane markings or lane departures; accuracy will
vary based on weather, speed, and lane marker
condition. It is always your responsibility to safely
operate the vehicle an d avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly or may work
improperly under the certain conditions:

resumes after the signals are off.
() If you make a lane change without operating the turn signals, the LKAS

Monitors the lane
lines
■ Tactile and visual alerts
Rapid vibrations on the steering wheel
and a warning display alert you that
the vehicle is drifting out of a
detected lane.■ Steering input assist
The system applies torque to the steering to keep the vehicle between the left
and right lane lines. The applied torque becomes stronger as the vehicle gets
closer to either of the lane lines.18 CLARITY PHEV CSS-31TRW6000.book 415 ページ ２０１７年８月３１日　木曜日　午後２時４９分

Driving
Collision Mitigation Braking System TM
(CMBS TM
)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.
■ How the system works 1 Collision Mitigation Braking System TM
(CMBS TM
)
Important Safety Reminder
The CMBS TM
is designed to reduce the severity of an
unavoidable collision. It do es not prevent a collision
nor stop the vehicle automati cally. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS TM
may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions:

camera equipped with this system.
2 Front Sensor Camera P. 394
Be careful not to severely impact the radar sensor
cover.
1 How the system works
Rapid vibrations on the steering wheel alert you
when the your vehicle speed is between 19 and 62
mph (30 and 100 km/h) with an oncoming vehicle
detected in front of you.
When the CMBS TM
activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential coll ision is not determined.The radar sensor is
in the front grille.The camera is
located behind
the rearview
mirror.
The system starts monitoring the roadway ah ead when your vehicle speed is about 3
mph (5 km/h) and there is a vehicle in front of you. When to use
The CMBS TM
activates when: ●
The speed difference between your vehicle and a vehicle or pedestrian detected
in front of you becomes about 3 mph (5 km/h) and over with a chance of a
collision. ●
Your vehicle speed is about 62 mph (100 km/h) or less and there is a chance of a
collision with an oncoming detected ve hicle or a pedestrian in front of you.18 CLARITY PHEV CSS-31TRW6000.book 439 ページ ２０１７年８月３１日　木曜日　午後２時４９分

Driving The CMBS TM
may activate even when you are aw are of a vehicle ahead of you, or
when there is no vehicle ahead . Some examples of this are:
■ When Passing
Your vehicle approaches another vehicle ah ead of you and you change lanes to pass.
■ At an intersection
Your vehicle approaches or passes another vehicle that is making a left or right turn.
■ On a curve
When driving through curves, your vehicle comes to a point where an oncoming
vehicle is right in front of you.
■ Through a low bridge at high speed
You drive under a low or narrow bridge at high speed.
■ Speed bumps, road work sites, tr ain tracks, roadside objects, etc.
You drive over speed bumps, st eel road plates, etc., or yo ur vehicle approaches train
tracks or roadside objects [such as a traffi c sign and guard rail] on a curve or, when
parking, stationary vehicles and walls.■ With Little Chance of a Collision 1 Collision Mitigation Braking System TM

For the CMBS TM
to work properly:
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 apply any coverings or paint to the radar
sensor area. Do not put a sticker on the emblem or
replace the emblem.
These can impact CMBS TM
operation.
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
CMBS TM
off button and take your vehicle to an
authorized Honda Clarity Plug-In Hybrid dealer.
Have your vehicle checked by an authorized Honda
Clarity Plug-In Hybrid deal er 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 Plug-In Hybrid 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.18 CLARITY PHEV CSS-31TRW6000.book 446 ページ ２０１７年８月３１日　木曜日　午後２時４９分
