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.
3WARNING
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.

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.

4.Add fuel very slowly.
u The automatic fuel tank vent valve does 
not operate when the fuel fill door is 
opened manually. Trying to add fuel too

cause fuel vapors to be pushed out the 
filler pipe and can cause a small amount 
of liquid fuel to  be spilled onto the 
ground.
