Checking and Replacing Fuses
The wiring circuits in the vehicle are protected from short circuits by fuses. This greatly reduces the chance of damage caused by electrical problems.
To check a fuse, 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.
Fuses of the same amperage can be temporarily borrowed from another fuse location if a fuse goes out. Replace the fuse as soon as possible.
Note
- Before replacing a fuse check that the key has been removed from the ignition and that all the services are switched off and/or disengaged.
- Do not repair fuses and never replace a blown fuse with one that has a higher amp rating. This can cause damage to the electrical system and fire.
- Never replace a broken fuse with anything other than a new fuse. Use always an intact fuse of the same color.
- If a fuse blows again contact a qualified service center.
