The power supply networks of the vehicle are protected by fuses, circuit breakers or relays; fuse boxes and relay boxes are situated in the engine compartment and at left end of the CID. The engine compartment fuse and relay box is installed on the top left side of the vehicle, beneath the air filters housing and the actual fuses or relays can be located by opening the cover where a guide of the locations is engraved. The under-dash fuse and relay box is located at the left kick panel and it is necessary to pull the kick panel out to get to the fuses. Mini and maxi fuses featuring a blade terminal configuration safeguard a number of circuits, and can be squeezed out and plugged in without the use of additional tools. Every fuse is assigned for particular circuits, and their names are marked at the lid of the fuse board, but if a label is illegible or absent, there is a general list of fuses and relays in the instruction manual. When an electrical component does not work, the first thing to check is the fuse, and the most effective way to do this is to use a test light to probe the end of the exposed tips of each fuse; if power is felt from one and point but not the other, then the fuse is dead, which can be further confirmed by simple observation. The fuses that are broken should be replaced by the ones of corresponding type since although physically one can place different type of fuses in the same slot, they must be of the correct rating to protect the electrical circuit adequately. If the new fitting fuse blinks out as soon as it was installed then it should not be replaced until the core cause which is most of the time a short circuit as the result of a faulty or worn out wire is checked and fixed.

If an electrical component fails, checking the fuse first is essential, using a test light to check for power at the terminal tips; a blown fuse can also be identified visually.

Fusible links are similar to large fuses and are located in the engine compartment fuse/relay box; they can be replaced after disconnecting the negative battery cable.

Each fuse is designated for specific circuits, which are identified on the fuse panel cover. A complete guide to all fuses and relays is available if the cover is difficult to read or missing.

Another auxiliary fuse and relay box is located on the firewall, to the left of the brake master cylinder reservoir.

The vehicle's electrical circuits are protected by a combination of fuses, circuit breakers, and relays.
