1The various interior trim panels are secured
by a variety of screws and plastic clips.
2Where press-fit plastic fasteners are used,
it is advisable to use a forked tool similar to
that shown to remove them, to avoid damage
to the clips and the trim panel (see
illustration).
3Removal and refitting of most of the trim
panels is self-explanatory but in all cases,
care must be taken, as the panels are easily
damaged by careless handling and the use of
sharp instruments to release clips.
