and plastic key code card.
To remove the trim panel, lift it from the
rear retaining hooks, while pulling it toward

reinstall it, line up the tabs with the grooves
on the panel, drop the panel back into

key code card.
After replacing a fuse, return the key code
card to the original position. To reinstall
the trim panel, lineup the tabs with the
grooves on the panel, drop the panel back
into place, and then push it shut to reinstall
the trim panel.

CHANGING A FUSE
Fuses WARNING
Always replace a fuse with one that
has the specified amperage rating.
Using a fuse with a higher amperage
rating can cause severe wire damage and
could start a fire. If electrical components in the vehicle are
not working, a fuse may have blown. Blown
fuses are identified by a broken wire within
the fuse. Check the appropriate fuses
before replacing any electrical
components.
