On convertible models, you must also remove the trunk access panel. It's at the upper back of the trunk. Turn the two wing fasteners under the trunk edge a quarter turn counterclockwise to 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. 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. To remove the jack and wheel wrench, loosen and remove the bolt and remove the plastic cover. 5-24
