Fuel System

The IPC provides fuel system messages for the following concerns and status:

• Check fuel fill inlet message (gas) - warns the driver there is a problem with the fuel fill inlet pipe resulting in a significant evaporative emission leak following vehicle refueling
• Fuel door opening (PHEV) - informs the driver to wait approximately 15 seconds while the fuel system depressurizes
• Fuel door open (PHEV) - informs the driver the fuel system has depressurized and it is safe to refuel
• Refuel system status display (PHEV) - displays when the fuel system fails to depressurize or the fuel filler door fails to open
• Fuel maintenance mode display (HEV) - displays when the engine needs to run to maintain fuel freshness
• Check fuel door to avoid check engine light (PHEV) - displays as a reminder to close the fuel door
