Checking and Replacing Fuses

Fuses, fusible links, and circuit breakers protect your vehicle’s electrical system from overloading. If any electrical equipment in your vehicle does not operate, the system may have been overloaded and blown a fuse or tripped a circuit breaker. Before you replace or repair any electrical parts, check the appropriate fuses or circuit breakers.

  1. Be sure the ignition switch is pushed to the OFF or LOCK position and the headlight switch is turned to OFF.
  2. Open the fuse box cover.
  3. Remove the fuse with the fuse puller.
  4. To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse.
  5. If a new fuse also opens, have the electrical system checked and repaired by an Infiniti dealer.

Notice

  • Never use a fuse of a higher or lower amperage rating than that specified on the fuse box cover. This could damage the electrical system or cause a fire.
  • Always disconnect the battery before servicing high current fuses.
  • Never replace a broken fuse with anything other than a new fuse. Use always an intact fuse of the same color.
