Checking and Replacing Fuses

1. In order to find the fuse panel, you must
first remove the cover from the lower edge
of the instrument panel. You can do this by
pulling on handle to disengage the fasteners.

2. On the fuse panel cover, find the number of
the fuse you want to check. The diagram on
the cover tells you where to locate the fuse
on the panel.
The underside of the cover also contains a
fuse pulling tool in case you need to replace
a blown fuse.
3. Check the fuse to see if it is blown. Look
through the clear side of the fuse to see if
the metal wire inside is separated. If it is,
the fuse is blown and should be replaced.
