 Danger	Risk of death. Death may occur if body parts are drawn into rotating vehicle parts.	Do not insert your hand into rotating parts. Wear closed and snug-fitting work clothes. Secure area of rotating vehicle components against unauthorized access.	AS00.00-Z-0004-01A
 Danger	Risk of death when working on component parts and systems with U >= 30 V alternating voltage (AC) or U >= 60 V direct voltage (DC)	Do not touch damaged or defective live component parts and lines or non-insulated electrical connections and lines.	AS00.00-Z-0035-01A
 Danger	Risk of explosion caused by fuel igniting, risk of poisoning caused by inhaling and swallowing fuel as well as risk of injury to eyes and skin caused by contactwith fuel.	No fires, sparks, open flames or smoking. Pour fuels into suitable and appropriately marked containers only. Wear protective clothing when handling fuel.	AS47.00-Z-0001-01A

	When removing the couplings at the ME-SFI [ME] control unit, first remove the center coupling; during attachment, the center coupling D is the last to be attached.
	Note on measuring equipment/test connection column. The numbers entered in brackets, e.g. in  1.0 (2A) mean:
	A = coupling A in wiring diagram
	2 = socket 2 in wiring diagram
	Ignition OFF
	Connect test wiring harness with socket box to ME-SFI [ME] control unit (N3/10) according to connection scheme.
	Plug with red identification is currently not yet required, as still no function available in ME-SFI [ME] control unit.
