Maxifuse/Relay Center To check the fuses in this underhood fuse center, turn the two knobs one-quarter turn counterclockwise and loosen the metal wing nut on the passenger side of the cover. Then remove the cover. The inside of the cover has a chartthat explains the features and controls governed by each fuseand relay. If you ever have a problem on the road and don't have a spare fuse, you can "borrow" onethat has the same amperage. Just pick some featureof your vehicle that you can get along without -- like the radio or cigarette lighter -- and use its fuse, if it is the correct amperage. Replace it as soon as you can. There are two fuse blocks in your vehicle: the driver's side and passenger's side fuseblocks. Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combinationof fuses, circuitbreakers and fusiblethermal links. Thisgreatly reduces the chance of damage caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replacethe fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. 6-56
