To disconnect the cables on the fuse blocks, press the locking slide in the direction of the arrow and disconnect the connectors.
Only disconnect the cables of the fuse blocks and relay bases if these are routed into both the interior and the engine compartment or component compartment. To prevent mix-ups, group disconnected cables together into bundles and mark.
For cables which are routed through the housing of the fuse and relay box without a separation point, determine the best disconnection or separation option outside the fuse and relay box in the engine compartment, component compartment or interior and disconnect cables or connectors. To do this, loosen or remove any cover under the instrument panel and floor covering in the footwell.
