	Check
1	Check whether vehicle is affected by measure	Model 447 as of 051576 up to 225856	SM82.10-S-0030-01AAA
		Model 639 as of 268055 up to 885167 For authorized Mercedes-Benz service partners, only the entry in the "Extended VEGA Application" (EVA) system, in the "Current" tab is decisive. An additional test of the affected vehicles in the workshop information system (WIS) or vehicle list is thereby not necessary.	SM82.10-S-0030-01AAB
	Document
2	Addition of code L10 (left-hand traffic headlamp) into Vehicle Documentation (VeDoc) in "Codes" screen	The code L10 (left-hand traffic headlamp) can only be entered into the Vehicle Documentation (VeDoc) by a user with write permission. If no-one with change authorization is available, the "Wholesale" level must be contacted first, e.g."Market Performance Center" (MPC), "Logistics Center" (LC) or "European Logistics Center" (ELC). If, for organizational reasons, they are unable to provide assistance, you may then, as an alternative, contact the VeDoc Hotline per ticket in the XENTRY Support (XSF) system. To rule out routing errors it is advisable to generate the Ticket in "XSF" from inside VeDoc. In this instance, the ticket must be forwarded in "XSF" from the responsible "Wholesale" level to the VeDoc Hotline.

Observe the applicable legal requirements and regulations of the country in question with regard to the proper and environmentally-compatible scrapping procedure. During the course of further technical development, the "zero-position adjustment" on model 447 was integrated in XENTRY Diagnostics into the "Lamp unit commissioning" process. Therefore, in XENTRY Diagnostics, the "zero-position adjustment" may no longer be called up separately.	AR82.10-S-4720S

4	Connect battery charger
		Model 447 During the entire work procedure a sufficiently large voltage supply must be provided for the vehicle's on-board electrical system. Otherwise any undervoltage that occurs may damage the control units. Use the charger to ensure that an adequate power supply (min. 12.5 V) is provided for the on-board electrical system battery. Is the charger already connected to the vehicle. ↓ Proceed with step 5.	AR54.10-S-1127E

7	Perform SCN coding of instrument cluster control unit (AAG) (A1/1)
		Model 447	AR54.21-S-0015E
		Model 639 To do so, call up following menu items: Control units view → A1/1 - Instrument cluster (IC) (code: JK5) → Adaptations → Configuration → SCN → Update of SCN coding To do so, call up the following menu items on model 639: Main group → Control units → Information and communication → IC - Instrument cluster → Control unit adaptations → Coding → Run SCN coding.
