The instrument panel fuse block is located behind the left side of the instrument panel. Swing the unit down and remove the access cover to access the fuses within the fuse block; fuses should be identified on the cover. Spare fuses and a fuse puller should always be kept here. The fuse block uses miniaturized fuses, designed for increased circuit protection and greater reliability. Various convenience connectors, which snap-lock into the fuse block, add to the serviceability of this unit. To remove a blown fuse, simply pull it from its terminals. When replacing fuses, only use the correct amperage replacement fuse. Each fuse has a number stamped on the top which indicates the amperage rating. Damage to the electrical system may result if the incorrect fuses are used.

Circuit breakers are used in the electrical system. The breakers are designed to `trip' when an overload is placed on the system. The breaker automatically resets when the overload is removed. The breakers are located in this fuse panel.

The underhood fuse and relay center is located on the firewall under an easily-removable plastic sight shield. Each fuse cluster is in turn protected by its own plastic covering. These units house high-amperage fuses along with additional relays, and a circuit breaker in the left side block. All should be identified on the unit.
