WARNING: This page is about a different car, the 2012 Dodge Charger. However, it is still accessible from the selected car via links, so may be relevant.
The HomeLink® transceiver operates on a non-switched source of battery current so the unit will remain functional, regardless of the ignition switch position. For more information on the features, programming procedures and operation of the HomeLink® transceiver, refer to the owner's manual in the vehicle glove box.
