Fuses and Circuit Breakers If the vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. The wiring circuits in the vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and don't have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of 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. Instrument Panel Fuse Block The instrument panel fuse block access door is located on the driver side edge of the instrument panel. Pull off the cover to access the fuse block. 6-130
