What does the loose fuel cap warning mean?
If you see the loose fuel cap warning shown in the vehicle information display, it usually means that the gas cap isn’t screwed down all the way. If the gas cap’s seal doesn’t lock in, the system will detect a leak and light up both the Check Engine Light and display a message in the vehicle information window. Here’s how you need to proceed:
Open the fuel door.
Remove the gas cap.
Check the seal for any debris or damage.
Replace the gas cap.
Tighten it completely until you hear it click.
Press the “next” button on the information display. Hold it for about a second.
The gas cap warning should turn out.
If the message appears again, have your car inspected.
