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 time to the rear fuse block CIGAR/AUX relay coil. Battery positive voltage (B+) is supplied at all time through the rear fuse block CIGAR Fuse to the CIGAR/AUX relay switch. The rear integration module (RIM) controls the CIGAR relay by supplying ground to the CIGAR relay coil via CKT 1399 (DK GRN). The RIM will activate the CIGAR relay when the ignition switch is turned to the START, ON, or ACCY position. The RIM will also keep the CIGAR relay active for 10 minutes after the ignition switch is turned from any of the previous positions to the OFF position.

When the CIGAR relay is active, battery positive voltage (B+) is supplied to the underhood fuse block C/LTR Fuse and AUX PWR Fuse via CKT 70 (PNK). Battery positive voltage (B+) is supplied through the C/LTR Fuse to the cigar lighter via CKT 2040 (ORN). Battery positive voltage (B+) is supplied through the AUX PWR Fuse to the auxiliary power front outlet and rear outlet via CKT 3540 (ORN). The cigar lighter receives ground from G201 via CKT 450 (BLK). Both auxiliary power outlets receive ground from G301 via CKT 650 (BLK).
