First drive cycle

During the first drive cycle after a cold start, the PCM alerts the driver to check the fuel fill cap by showing a "CHECK FUEL CAP" (2005 model) ("TIGHTEN FUEL CAP" (2006 model)) message in the multi-information display (A), and it stores Temporary DTC P0457 "Evaporative Emission (EVAP) System Leak Detected/ Fuel Fill Cap Loose or Missing". Tightening the fuel cap does not make the message go off immediately.
