Check the last few pages of the User Manual. With a little searching I found that P0452 is a fuel tank pressure sensor circuit fault. It's not dangerous, but don't expect your fuel gage to give you an accurate reading.

if you fill your car up and leave it running it will some times give you that code. Also if the gas cap is not tight, or gas cap is bad.
