			=== Limiting opening height ===

			The trunk lid opening height can be limited when transporting goods on a roof rack (e.g. presence of an MB sport luggage container).

			When activated, the trunk lid opens to approximately the height of the roof edge.

			You can activate the limiting opening height of trunk lid using the control system or menu in instrument cluster.

			\|}

			=== Nomalizing opening height ===
			In case trunk fails to open to its full height, normalization of opening height is necessary.

			Trunk opening has a reset procedure using the switch on the driver's door panel. Instead of listening for the click sound, continue to hold the switch for an additional 15 seconds. Do this with the trunk in the fully opened position, and then again from the closed position. Sometimes it is necessary to go through two full open/close cycles to get the trunk opening height to be reset correctly.

			Alternatively, trunk lid opening height can be normalized using appropriate adaptation functionality under PSE module in DAS.

			A common issue with hazard warning triangle is plastic triangle breakage from metal stand.

			Broken triangle can be fixed with super glue and cable ties (fixation with cable ties requires drilling small hole in one side of the plastic triangle).
