2. Remove the outer frame from the Head Up
Display unit. To do this, disengage the 6
latches which secure it to the main body of
the Head Up Display (Figure 1). Use a small
offset pick tool to carefully pry the latches
open, while at the same time carefully
applying pressure to lift the frame, to prevent
the latches from re-engaging (Figure 2).

Figure 1. Six latches are shown with red arrows.

Figure 2. Carefully use a small angled pick tool to
delicately disengage the six latches.

3. After all latches are disengaged, carefully remove the frame by gently lifting and pulling it out between
the Head Up Display and instrument panel.
Note:
Use a high level of caution during steps 2 and 3 not to break the retaining clips when disengaging and
when pulling the frame out. The clips are fragile, and the frame is not available as a service part. If
damaged, the complete Head Up Display must be replaced.
4. Trim and apply adhesive felt tape to the
underside of the frame. The eight standoffs
molded into the surface and marked with red
arrows MUST NOT be covered; otherwise,
the retaining clips will not re-engage (Figure
3).

Figure 3. Eight positive standoffs that must not be
covered by the felt tape are shown with red arrows.
5. Reinstall the opposite of removal.
Tip: Use care to ensure all eight of the Head Up Display frames are securely latched. An
audible click sound can be heard once these are properly latched.
