Driving
■ There is no vehicle ahead
Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your ve hicle from traveling at
the set speed, ACC with LSF accelerates your
vehicle to the set speed, and then maintains it.
■ When you depress the accelerator pedal
You can temporarily increase the vehicle speed . In this case, there is no audible or
visual alert even if a vehicl e is in the ACC with LSF range.
ACC with LSF stays on unless you cancel it . Once you release th e accelerator pedal,
the system resumes an appropriate speed fo r keeping the followi ng-interval while a
vehicle ahead is within the ACC with LSF range.
■ A vehicle detected ahead is within ACC with LSF range and slows to a stop
Your vehicle also stops, automatically. The
Stopped message appears on the driver
information interface.
When the vehicle ahead of you starts again,
the vehicle icon on the driver information
interface blinks. If you press the RES/+ or
−/SET button, or depress the accelerator
pedal, ACC with LSF operates again within the
prior set speed. 1 When in Operation
Limitations
You may need to use the brake to maintain a safe
interval when using ACC wi th LSF. Additionally, ACC
with LSF may not work properly under certain
conditions.
2 ACC with LSF Conditions and Limitations
P. 4083
WARNING Exiting a vehicle that has been stopped
while the ACC with LSF system is operating
can result in the ve hicle moving without
operator control.
A vehicle that moves without operator
control can cause a crash, resulting in
serious injury or death.
Never exit a vehicle when the vehicle is
stopped by ACC with LSF.A vehicle icon with dotted-line
contour appears on the driver
information interface
1 When you depress the accelerator pedal
While the accelerator pedal is depressed, the system
does not apply the brakes to keep the following
interval, as well as the BRAKE message on the driver
information interface does not appear.19 CLARITY PHEV-31TRW6100.book 407 ページ ２０１８年１０月２５日　木曜日　午後２時２９分

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. 396
■ Environmental conditions
Driving in bad weather (r ain, fog, snow, etc.).

■ 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 your vehicle or the vehicle ahead of you is driving on one edge of the lane. 1 ACC 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 Plug-In Hybrid dealer:
• The vehicle impacted a bump, curb, chock,
embankment, etc.

Driving Increase or decrease the vehicle speed using the RES/+ or −/SET button on the
steering wheel.
• Each time you press the RES/+ or −/SET button, the vehicle sp eed is increased or
decreased by about 1 mph or 1 km/h accordingly.
• If you press and hold the RES/+ or −/SET button, the vehicle speed increases or
decreases by about 5 mph or 5 km/h accordingly.■ To Adjust the Vehicle Speed 1 To Adjust the Vehicle Speed
If a vehicle detected ahead is going at a speed slower
than your increased set speed, ACC with LSF may not
accelerate your vehicle. This is to maintain the set
interval between your vehi cle and the vehicle ahead.
You can switch the displayed set speed
measurements on the driver information interface
between mph and km/h.
