Checking and Replacing Fuses

A fuse is an element for protecting the electrical system. A fuse will trip (i.e. it will blow) in the event of a failure or improper interventions in the electrical system.

If an electrical device is not working, check whether the respective fuse is blown. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Check those fuses first that protect the failed component, but check all the fuses before deciding that a blown fuse is not the cause. Replace any blown fuses with another with the same amperage (same color) and check the component’s operation.


  • Before changing a fuse, check the ignition key has been removed and that all the other electric devices have been turned off/disabled.
  • Never replace a broken fuse with anything other than a new fuse. Always use a fuse of the same color.
  • Never change a fuse with another amperage. This can cause damage to the electrical system and fire.
  • If the fuse blows again, have the vehicle inspected at a qualified service center.

Passenger Compartment Fuse Box

The interior fuse panel is on the lower instrument panel just to the left of the steering column. A label is stamped on the fuse panel cover to identify each fuse for ease of replacement.

Engine Compartment Fuse Box

Your vehicle is equipped with an electrical power distribution center located in the engine compartment near the battery.

This power center houses plug-in “Cartridge” fuses which replace in-line fusible links. The power center also contains “Mini” fuses and plug-in full and mini ISO relays. A label inside the latching cover of the center identifies each component for ease of replacement, if necessary. “Cartridge” fuses and relays can be obtained from your authorized dealer.
