	Risk of injury caused by fingers being jammed or pinched when removing, installing or aligning hoods, doors, trunk lid/rear-end door or sliding roof.	No parts of the body or limbs should be within the operating area when the components are moving.	AS00.00-Z-0011-01A
	Risk of injury caused by scraping or cutting body parts on sharp vehicle parts	Always wear protective gloves when working on or near sharp and non-deburred vehicle parts. Deburr repair panels.	AS00.00-Z-0017-01A

	Preparation
1	Prepare adhesive cartridge.		AR77.21-P-1000-01A
		Adapter	Fig 5
	Remove
2	Fully open panoramic sliding sunroof.
3	Determine gap dimensions between front stationary element (1) and windshield and note down.	Feeler gauge	Fig 2
4	Release wind deflector (2) from left and right mount.		AR77.21-P-0100GQ
5	Remove terminal strip (3) from front stationary element (1) with a long wedge (4).	Long wedge	Fig 3
6	Cut off weatherstrip (5) with a suitable knife (6).
7	Position shields (7) at left and right on front stationary element (1).	Ensure that outer edges of front stationary element (1) are protected by shields (7) before cutting with cutting wire. Otherwise, front stationary element (1) will be damaged.
		Set of shields	Fig 4
8	Attach cup suction tool to front stationary element (1).
	Risk of injury due to snapping or warming up of cutting wire and due to splinters when cutting out glued panoramic roofs	Wear cut-proof gloves and safety glasses.	AS77.21-Z-0002-01A
9	Cut through adhesive beads (8) of front stationary element (1) with cutting wire and remove front stationary element (1) from the vehicle.	Carefully insert cutting wire. Otherwise the adjacent components can be damaged.
		Ensure that the outer edges of front stationary element (1) are not damaged by the hot cutting wire. Otherwise, front stationary element (1) will be damaged. Helper required. Observe cutting sequence. First cut (A), second cut (B), then third cut (C).
10	Remove shields (7).	Set of shields	Fig 4
	Install
11	Prepare front stationary element (1) for installation.		AR77.21-P-0803-02GQ
		Before starting work, all component parts, materials, and tools must be prepared for the installation of the front stationary element (1). Otherwise it may not be possible to maintain permissible processing and joining times. Only use the repair kit approved by the manufacturer from the replacement part system. Otherwise, the front stationary element (1) and the panorama roof frame will have adhesion problems.
12	Prepare body flange for installation of front stationary element (1).		AR77.21-P-0803-03GQ
		Only use the repair kit approved by the manufacturer from the replacement part system. Otherwise, the front stationary element (1) and the panorama roof frame will have adhesion problems.
13	Apply adhesive material to front stationary element (1).		AR77.21-P-0803-04GQ
		Apply adhesive material as quickly as possible and position front stationary element (1) on the body flange and fix it in place. Otherwise, the strength of the adhesively bonded connection is impaired and the required adhesion of the adhesive material is not guaranteed. Only use the repair kit approved by the manufacturer from the replacement part system. Otherwise, the front stationary element (1) and the panorama roof frame will have adhesion problems.
14	Install front stationary element (1) with a helper.		AR77.21-P-0803-05GQ
		The vehicle must not be driven for at least 3 hours after gluing in the front stationary element (1). Otherwise, the strength of the adhesively bonded connection is impaired and the required adhesion of the adhesive material is not guaranteed. To load front stationary element (1), use weights with large surfaces, e.g. sandbags. Otherwise, front stationary element (1) will be damaged. Observe dimensions noted when aligning.
		Feeler gauge	Fig 2
15	Remove feeler gauges.	Remove feeler gauges only after adhesive material has cured.
		Otherwise, the gap dimensions may change. Feeler gauge	Fig 2
16	Fasten left and right mount of the wind deflector (2).		AR77.21-P-0100GQ
17	Close panoramic sliding sunroof.
18	After the adhesively bonded connection is completely cured, remove weights for weighing down the front stationary element (1).
	Clean
19	Clean working area.
