with a change in the temperature.

always add a minimum of 1.3 US gal
(5.0 L) of fuel.
9. After filling, replace the fuel fill cap,
tightening it until you hear it click at least
once.

1How to Refuel
If the fuel fill door does not open after you press the
button, even after the display changes to Ready, you
can manually open the door.
2 If You Cannot Unlock the Fuel Fill Door
P. 584
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.
If you repeatedly fill the tank with less than the
specified minimum amount of fuel, the malfunction
indicator lamp may come on. If this happens, have
your vehicle checked by a dealer.
Do not continue to add fuel after the filler nozzle has
automatically stopped. Additional fuel can exceed
the full tank capacity.
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.
