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. | |
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. | |
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. | |

| 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. | ||
| 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. | ||
| Check | ||
