How do you remote start a 2006 Hyundai Elantra?

My 2006 Hyundai Elantra comes with remote start, activated through some (evidently) secret combination of locking and unlocking with the key remote. I have looked in my owner's manual and Googled it, and I can't find the answer; I have only ever remote-started it accidentally, and now that winter is fast approaching and it's cold out, I want to know exactly how it works.|||Elantra came stock with a remote start, I find that hard to believe. If you think it has remote start then simply drive to the dealer and ask them how it works.
