Help: warning sound when headlight is on when you turn off the engine

Hi, I got my new sonata hybrid 3 weeks ago. I somehow remember that the car will give a warning beeping sound if i forget to shut down the headlight when i turn off the engine. But now the car doesnt do that anymore (i specifically left the headlight on and turn off the engine and no sound appears) Did i pop a fuse or anything, I'm not really sure how to investigate this. appreciate any help.

thanks

Eric
