How does my cigarette lighter work

Hi @luistirado

If you mean how does it literally work, here's a link that describes the principle of operation of a car cigarette lighter.

If you mean that it is not working, then the cigarette lighter plugs into a power outlet socket which is powered via a 15A mini fuse #5 (for model years 2007-2009) and a 20A mini fuse #5 (for model years 2010-2013) which is located in the passenger compartment fuse box. Check if the fuse is OK.

If the fuse is OK, it could still be a faulty cigarette lighter. Perhaps try using it in the power socket in another car and check if it works OK.
