Flat Mat Hook
WARNING: This page is about a different car, the 2012 Subaru Outback and 2012 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.
Apply load to the backrest and check the flat mat hook.
NOTE:
If the backrest does not keep sufficient tension when subject to load, some hooks may be detached. If any hook is deformed and detached, replace it with a new hook.
