OPERATION
The power distribution system for this vehicle is designed to provide safe, reliable, and centralized distribution points for the electrical current required to operate all of the many standard and optional factory-installed electrical and electronic powertrain, chassis, safety, security, comfort and convenience systems. At the same time, the power distribution system was designed to provide ready access to these electrical distribution points for the technician to use when conducting diagnosis and repair of inoperative circuits. The power distribution system can also prove useful for the sourcing of additional electrical circuits that may be required to provide the electrical current needed to operate many accessories that the vehicle owner may choose to have installed.

The majority of electrical system fuses and relays are housed in the two Power Distribution Centers (PDC). One is located in the engine compartment, the Totally Integrated Power Module (TIPM). See Electrical - Wiring/Power Distribution/MODULE, Totally Integrated Power (TIPM) - Description . The PDC is located next to the battery in the rear of the vehicle. The PDC located next to the battery is replaced only as part of the body wiring harness.

Sedans are equipped with two 12-volt electrical outlets. Five-door models are equipped with three 12-volt electrical outlets. The outlets are located in the following locations
- Cargo area right quarter trim panel (Five-door models only).
- Inside the center console.
- Next to the ash receiver in the center stack.
The outlets in the console and quarter trim panel have power at all times, and include tethered covers. The outlet in the ash receiver tray is shipped with power available only when the ignition is in the ON position. This outlet can be changed to provide power at all times by moving a fuse in the fuse block.
