First Drive Cycle

During the first drive cycle after a cold start, the ECM/PCM stores Temporary DTC P0457 "Evaporative Emission (EVAP) System Leak Detected/Fuel Fill Cap Loose or Missing" if the fuel cap is loose or missing, but no indicator comes on, and no message is shown in the multi-information display (A).
