TO: ALL MERCEDES-BENZ CENTERS

Update Front SAM Parameters

specified values of the backup battery in the front SAM may be set too low. This may lead to fault messages in the instrument cluster. Dealers will
update the front SAM parameters at the next workshop visit.
Prior to performing this Service Campaign:
^ Please check VMI to determine if the vehicle is involved in the Campaign and if it has been previously repaired.
^ Please review the entire Service Campaign bulletin and follow the repair procedure exactly as described.
