button, even after the display changes to Ready, you
can manually open the door.
2 When You Cannot Unlock the Fuel Fill Door
P. 648
An internal valve automatically closes after 30
minutes from the moment you 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 automatically opens, a vent
valve in the fuel system also opens to allow the air
and the vapors being displaced 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.
