Service bulletin 24-BE-001H

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.

Follow the procedure outlined in this bulletin to update the AVN software to resolve this condition.
