1	Check if vehicle is affected by measure.	Affected vehicles: Retrofit rear Blind Spot Assist radar sensors (code: VS2RADSON) For authorized Mercedes-Benz service partners, only the entry in the "Extended VEGA Application" (EVA) system, in the "Current" tab is decisive. There is no need to also check the affected vehicles in the workshop information system (WIS) or vehicle list.	SM54.71-S-0112-01AAA
	Update Vehicle Documentation (VeDoc)
2	Remove special equipment code IX8 (Special control system for Blind Spot Assist) or code WS0 (Plant control code) from VeDoc.	If codes are present in VeDoc. An administrative employee must perform all processing in the VeDoc system.  Codes can only be removed from VeDoc by a user with write permissions. If no one with change authorization is available, contact the "Wholesale" level first, e.g. "Market Performance Center" (MPC), "General Distributor" (GV), "Logistics Center" (LC), "Regional Logistics Center" (RLC) or "European Logistics Center" (ELC). If, for organizational reasons, the "Wholesale" level is unable to provide the assistance mentioned here, you may then, as an alternative, contact the VeDoc Hotline per ticket in the XENTRY Support (XSF) system. It is recommended that a ticket is generated in "XSF" from inside Vehicle Documentation (VeDoc) to rule out any routing errors. In this instance, the ticket must be forwarded in "XSF" from the responsible "Wholesale" level to the VeDoc Hotline.
3	Enter special equipment code JA7 (Blind Spot Assist) in VeDoc.	If code is not present in VeDoc. An administrative employee must perform all processing in the VeDoc system. Codes can only be added to VeDoc by a user with write permissions. If no one with change authorization is available, contact the "Wholesale" level first, e.g. "Market Performance Center" (MPC), "General Distributor" (GV), "Logistics Center" (LC), "Regional Logistics Center" (RLC) or "European Logistics Center" (ELC).
