Checking

7

Switch on ignition, completely close Vario roof using Vario roof switch and check position of lock hooks (3) in left and right mount (2)

 The lock hooks (3) should be centered in the opening (arrows C) in the mounts (2) when the catch is locked. The lock hooks (3) should not make contact with the mounts (2) or the window (4) to prevent cracking noises while driving.

Adjust

8

Open Vario roof approx. 10 cm using Vario roof switch and position suitable spacer, e.g. wooden block, between Vario roof front section (12) and crossmember above windshield (13). Then switch off ignition

 The Vario roof closes automatically approx. 7 seconds after ignition is switched off. Thereby, the shim will be pinched
The shim should keep the Vario roof open so that the mounts (2) can be removed.

9

Unscrew nuts (5) from left and right mounts (2) and remove left and right mounts (2) together with spacer (6)

 One or more spacers (6) may be present at the attachment points of the mount (2).

10

Adjust position of lock hook (3) in mount (2) by removing or inserting spacers (6) on inner mount attachment point (7)

 It may be necessary to remove or insert several spacers (6) on the inner attachment point mount (7) to achieve the correct position of the lock hook (3) in the opening (arrows C) of the mount (2).

11

Adjust height offset dimension (a) by removing or inserting spacers (6) on outer attachment point mount (8) on left and right mount (2)

 The number of spacers (6) which can be inserted is limited because, otherwise, the lock hook (3) hits against the upper panel of the mount (2). In this case, additionally remove washer (10) from inner attachment point of lock (9)

12

Position left and right mount (2) on installation location and screw on nuts (5)

 Tighten nuts (5) only to the extent that the mounts (2) still can be moved.

13

Remove and reinstall lock (11) on front lock for adjustment

Only if it is necessary to adjust the height offset dimension (a) on the inner attachment point of lock (9) must be corrected.
