Checking and Replacing Fuses

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly 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, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating. The fuse puller is located on the rear compartment fuse block.


  • Before replacing a fuse, turn off the respective switch and the ignition.
  • Never use a fuse of a higher or lower amperage rating than that specified. This could damage the electrical system or cause a fire.
  • Never replace a broken fuse with anything other than a new fuse (such as wire, foil, etc). Use always an intact fuse of the same color.

There are two fuse blocks in your vehicle: one in the engine compartment and one in the trunk.
