Service bulletin NCU-2020060021

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

The operator's manual for the above vehicles does not comply with current specifications. "Daimler AG" may be documented as the manufacturer in the operator's manual. The new manufacturer is "Mercedes-Benz AG." We thus ask that you place the supplementary booklet into the vehicle. The work required for this purpose can be found in the attached work description.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
