Database: CHARM
CHARM manuals were retrieved from a set of DVDs released in late 2013. These manuals are usually the most detailed for the years in which they're available, but occasionally have missing or cut-off images.
Database: LEMON
LEMON manuals were retrieved in late 2025, so they have more up to date technical bulletins for example. However, they tend to be less detailed for older vehicles.
