The workshop manual of the Carrera 4 also includes that for the Carrera 2. The Carrera 4 acts as the basis for description of the repairs in the manual. "Carrera 4" also appears on every page in the header line.

Deviating descriptions for repairs on the Carrera 2 follow those of the Carrera 4. These repair descriptions for both models are separated by a yellow sheet.

"Carrera 2" appears on all pages in the header line after the separating sheet. The page number starts with 100 as an additional distinction.
