Quick Reference Guide There are three drive modes: ECON, NORMAL, and SPORT
Regardless of the drive mode that is acti vated, when the accelerator pedal is depr essed past a certain point, the engine starts . When this
occurs, electrical power generated by the en gine combines with electrical power from th e battery to provide greater driving force. If you
select ECON mode, the threshold for the engine to provide additional power is higher than it is when the vehicle operates under either of
the two sources. Note that if the accelerator pedal is depressed past the point at which you feel a click, the engine will star t in the ECON
mode with the HV indicator off.
2 HV Button (P16)
To maintain fuel efficiency, keep steady pressure on the accelerator pedal and avoid aggressive acceleration and deceleration.

427uu When Driving u Tire Pressure Monitoring System (TPMS) - Required Federal Explanation
Continued
Driving
Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufa cturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a diff erent size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflat ion pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure tell tale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-inf lated tire causes the tire to
overheat and can lead to tire fail ure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability. 18 CLARITY PHEV CSS-31TRW6000.book 427 ページ ２０１７年８月３１日　木曜日　午後２時４９分

452 uu Refueling u How to Refuel
Driving How to Refuel 1. Stop your vehicle with the service station
pump on the left side of the vehicle in the
rear.
2. Put the transmission into ( P
.
3. Turn the power system off.
4. Press the fuel fill door release button.
u Please Wait appears for a few seconds
on the driver information interface.
5. When the message changes to Ready , the
fuel fill door automatically opens.
u You can now unscrew the fuel cap and
start refueling.
6. Remove the fuel fill cap slowly. If you hear a
release of air, wait unt il this stops, then turn
the knob slowly to open the fuel fill cap. 1 How to Refuel
This vehicle has a pressurized fuel system.
When the fuel vapor pressure inside the fuel tank is
high, it takes about 10 seconds for the vehicle to vent
the fuel tank. Once the pressure is vented, the driver
information interface changes from Please Wait to
Ready .
If the filler nozzle keeps tu rning off when the tank is
not full, there may be a problem with the pump's fuel
vapor recovery system. Try fi lling at another pump. If
this does not fix the problem, consult an authorized
Honda Clarity Plug-In Hybrid dealer.
Do not continue to add fuel after the filler nozzle has
automatically stopped. Addi tional fuel can exceed
the full tank capacity.
The filler nozzle automatically stops to leave space in
the fuel tank so that fuel does not overflow as a result
of changes in air temperature.3
WARNING Gasoline is highly flammable and explosive.
You can be burned or seriously injured
when handling fuel.
• Stop the engine, and keep heat, sparks,
and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.Fuel Fill Door

Driving
Fuel Economy and CO 2
EmissionsImproving Fuel Ec onomy and Reducing CO 2

Emissions Achieving fuel economy and reducing CO 2
emissions is dependent on several
factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accord ance with the messages displayed on the
driver information interface.
• Use the recommended viscosit y engine oil, displaying the API Certification Seal.
• Maintain the specified tire pressure.
• Do not load the vehicle with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle's underside
adds weight and increases wind resistance.■ Maintenance and Fuel Economy 1 Improving Fuel Economy and Reducing CO 2
Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test. For more

Maintenance
Checking and Maintaining Tires Checking Tires To safely operate your vehicle, your tire s must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■ Inflation guidelines
Properly inflated tires provid e the best combination of hand ling, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ifications page for the specified pressure.
Underinflated tires wear unev enly, adversely affect handli ng and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, are more pron e to road hazards,
and wear unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
At least once a month or before long trips , use a gauge to measure the pressure in
all tires. Even tires in good condition can lose 1–2 psi (10–20 kPa, 0.1–0.2 kgf/cm 2
)
per month.
■ Inspection guidelines
Every time you check inflation, also examine the tires and valve stems.
Look for:
• Bumps or bulges on the side or in the tr ead. Replace the tire if you find any cuts,
splits, or cracks in the side of the tire . Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have an authorized H onda Clarity Plug-In Hybrid dealer check
the wheel alignment.
• Excessive tread wear. 2 Wear Indicators P. 504
• Cracks or other damage around valve stem. 1 Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1 mile (1.6 km). If
necessary, add or releas e air until the specified
pressure is reached.
If checked when hot, tire pressure can be as much as
4–6 psi (30–40 kPa, 0.3–0.4 kgf/cm 2
) higher than if
checked when cold.
Whenever tire pressure is adjusted, you must
calibrate the TPMS.
2 TPMS Calibration P. 425
Have an authorized Honda Clarity Plug- In Hybrid
dealer check the tires if you feel a consiste nt vibration
while driving. New tires and any that have been
removed and reinstalled sh ould be properly balanced.3
WARNING Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instruction s in this owner’s
manual regarding tire inflation and
maintenance.18 CLARITY PHEV CSS-31TRW6000.book 499 ページ ２０１７年８月３１日　木曜日　午後２時４９分
