Refueling Fuel Information ■ Fuel recommendation
Use of a lower octane gasoline can cause a persistent, heavy metallic knocking noise
that can lead to engine damage.
■ Top tier detergent gasoline
Because the level of detergency and additive s in gasoline vary in the market, Honda
endorses the use of “TOP TIER Detergent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard jo intly established by leading automotive
manufacturers to meet the needs of today’s advanced engines.
Qualifying gasoline retailers will, in most cases, identify their gasoline as having met
“TOP TIER Detergent Gasoline” standards at the retail location. This fuel is
guaranteed to contain the proper level of de tergent additives and be free of metallic
additives. The proper level of detergent ad ditives, and absence of harmful metallic
additives in gasoline, help avoid build-up of deposits in your engine and emission
control system.
For further important fuel-related information for your vehicle, or on information on
gasoline that does not contain MMT, visit www.hondacars.com. In Canada, visit
www.honda.ca for additional information on gaso line. For more information on top
tier gasoline, visit www.toptiergas.com .
■ Fuel tank capacity: 7.0 US gal (26.5 liters)Unleaded gasoline, pump octane number 87 or higher 1 Fuel Information NOTICE
We recommend quality ga soline containing
detergent additives that help prevent fuel system and
engine deposits. In addition, in order to maintain
good performance, fuel economy, and emissions
control, we strongly reco mmend the use of gasoline
that does NOT contain harmful manganese-based
fuel additives such as MMT, if such gasoline is
available.
Use of gasoline with these additives may adversely
affect performance, a nd cause the malfunction
indicator lamp on your inst rument panel to come on.
If this happens, contact an authorized Honda Clarity
Plug-In Hybrid dealer for service.
Some gasoline today is ble nded with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 15% ethanol
by volume. Do not use gaso line containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.18 CLARITY PHEV CSS-31TRW6000.book 451 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

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

P. 562
An internal valve automatically closes after 30
minutes from the moment y ou press the fuel fill door
release button. When it does, do not continue to
refuel as fuel may spill out.
When the fuel fill door auto matically opens, a vent
valve in the fuel system also opens to allow the air
and the vapors being displace d by the fuel to escape.
This valve automatically closes, however, if the
refueling is not completed within 30 minutes. If this
happens, reinstall the fuel cap, close the fuel fill door,
and then follow these steps again to restart the
system. If you decide to a dd fuel after the vent valve
has automatically closed (i .e. after 30 minutes), do so
very slowly. Trying to add fuel too rapidly after the
vent valve has closed will cause fuel vapors to be
pushed out the filler pipe and could cause a small
amount of liquid fuel to be spilled onto the ground.Holder Fuel Fill Cap18 CLARITY PHEV CSS-31TRW6000.book 453 ページ ２０１７年８月３１日　木曜日　午後２時４９分
