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.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
