When a cigar lighter is pressed in, the cigar lighter heating element is provided a ground path and heats up. When the heating element reaches a predetermined value, the cigar lighter will pop up, thus interrupting the circuit. The auxiliary power outlet is active when an electrical accessory is plugged into the outlet.

Battery positive voltage (B+) is supplied at all times through the CIGAR fuse in the rear fuse block to the cigar relay switch in the rear fuse block. The rear integration module (RIM) controls the cigar relay by grounding the control circuit of the cigar relay. The RIM will activate the cigar relay when the ignition switch is turned to START, ON, or ACC position. The RIM will also keep the cigar relay active for 10 minutes in the retained accessory power state.

When the cigar relay is active, battery positive voltage (B+) is supplied to the C/LTR 1 fuse and C/LTR 2 fuse in the underhood fuse block. Battery positive voltage (B+) is supplied through the C/LTR 1 fuse to the rear cigar lighters. Battery positive voltage (B+) is supplied through the C/LTR 2 fuse to the rear auxiliary outlets and the front cigar lighter. The front cigar lighter and rear auxiliary outlets receive ground from G201. The rear cigar lighters receive ground from G302.
