Fig. 1, Location of the Main Fuse Box
A sticker inside the lid of the fuse box shows the locations of the fuses and describes the circuit(s) that each fuse protects (see Fig.). See Table. for descriptions of a typical set of fuses. The fuses in the main fuse box are mini blade-type fuses. Battery power fuses, located near the batteries, are bolt-in megafuses.
Because the electrical system is multiplexed, no relays are needed. The multiplexing module performs the functions normally provided by relays.
