You can use the cigarette lighter when the ignition key is in the "ON" or "ACC" position.
To use the cigarette lighter, push the handle of the cigarette lighter all the way in. When the cigarette lighter heats up, it will automatically return to its original position with a click.
Do not leave the cigarette lighter in the fully recessed position. This may damage the heating element and cause a fire.
If it is necessary to replace the cigarette lighter, use only a genuine Hyundai cigarette lighter or an equivalent one that is approved for installation.
Caution: Do not insert any electrical equipment other than genuine Hyundai equipment into the cigarette lighter socket.
