Find the plastic screw heads in the trim panel over the
spare tire. (See "Compact Spare Tire" in the Index for
more information about the compact spare.) Use a coin
or a key to turn the screw heads until the slots point
front and back to the unlock position. Gently lift the trim
panel's front forward edge and remove the panel.
If you have speakers in the trim panel, you may have to
disconnect the wire from the speaker. The speaker wire
may be long enough to remove the trim panel without
disconnecting the wire.
To remove the jack and wheel wrench, loosen and
remove the bolt and remove the plastic cover.
