NOTICE Adapt a standard brush (15 mm wide) using workshop equipment (bevel approx. 40º).

A small fine pored sponge is to be used for working with the Krytox special lubricating paste, e.g. a domestic sponge without abrasive surface which has been cut to size.

Check functioning.

• Check panoramic sliding roof for possible damage.
• Check function and noise of panoramic sliding roof.
• Fully open louvred roller blind of the panoramic sliding roof.

Clean the edges of the glass panel:

• Remove residual dirt and grease from the front and side edges of the glass panel with the aid of D 009 401 04 cleaning solution and a lint-free cloth -arrows-.

Clean and grease roof frame seal:

• Remove dirt and residual grease from the roof pillar seal using cleaning solution D 009 401 04 and a lint-free cloth -arrows-.
• Apply a thin film of Krytox G 052 141 A2 special lubricating paste to the seal of the roof pillar using a fine pored sponge -arrows-.

NOTICE After application of the special lubricant past it is to be ensured that no large visible residues remain.

All following operations described are to be repeated on the opposite side of the vehicle.

Clean the guide rails:

• Glass panel completely opened.
• For cleaning and greasing only the headpiece - VAS 6621- is to be used.
• Insert the headpiece - VAS 6621- at the rear of the guide rail -1- and turn through 90º -2-.
• Push the headpiece - VAS 6621- up to the centre of the guide rail in -the direction of arrow 3-.
• Turn the headpiece - VAS 6621- through 90º -4- and remove the tool -5-.
• Remove accumulated residual grease and dirt from the respective guide rail using a lint-free cloth (where necessary remove sand and fine dust from the guide rail using a workshop vacuum cleaner).
• The described procedure can be repeated several times, depending on the degree of soiling.

• Insert the headpiece - VAS 6621- into the front of the guide rail (next to the wind deflector) -1- and turn through 90º -2-.
• Push the headpiece - VAS 6621- up to the centre of the guide rail in -the direction of arrow 3-.
• Turn the headpiece - VAS 6621- through 90º -4- and remove the tool -5-.
• Remove accumulated residual grease and dirt from the respective guide rail using a lint-free cloth (where necessary remove sand and fine dust from the guide rail using a workshop vacuum cleaner).
• The described procedure can be repeated several times, depending on the degree of soiling.
• Repeat the process on the other side of the vehicle.

Grease the guide rail:

• Screw the headpiece - VAS 6621- -1- onto the thread of the G 060 751 A2 grease cartridge -2- in -the direction of arrow- and fit onto the window seal gun - VAG 1628- -3-.

• Fit the window seal gun - VAG 1628- with the headpiece - VAS 6621- to the end of the guide rail on the side -1- and turn through 90º -2-.
• Apply the G 060 751 A2 lubricating paste to the front part of the guide rail in -the direction of arrow 3- whilst at the same time operating the window seal gun - VAG 1628- smoothly.
• Turn the window seal gun - VAG 1628- with the headpiece - VAS 6621- through 90º -4- and remove -5-.
• Remove any excess lubricant from guide rails using a lint-free cloth.
• Repeat the process on the other side of the vehicle.

Clean and grease the sliding guide:

• Glass panel completely opened.
• Residual dirt and grease in the sliding guide is to be removed using a lint-free cloth.
• Operate the sliding sunroof through the cycle of movement and completely open the glass panel again.

NOTICE The lubricating grease is spread onto the guide rails during the operating cycle. Accumulated excess lubricant can be used for greasing the sliding guide.

• Apply G 060 751 A2 lubricating paste to the sliding guide with a brush -arrow-.
• Remove excess grease from the sliding guides and guide rail with a cloth.

Clean and grease ratchets for the sunroof mechanism:

• Place the glass panel in tilt position.
• From the vehicle interior: Free the ratchet of the sliding sunroof mechanism from residual dirt and grease with the aid of a lint-free cloth.
• Apply G 060 751 A2 lubricating paste to the ratchet of the sliding sunroof mechanism using a brush -arrow-.
• Remove excess lubricate with a lint-free cloth.
• Operate the roof system through the complete cycle of movement and check once again that all lubricating points are free of residual grease.

Check water drains for dirt:

• Open glass panel completely.
• Use a beaker -1- to pour water onto the opened glass panel in the guide rail -arrow-.

NOTICE Proceed with care to prevent water running into the vehicle interior.

Proceed so that water flows in both directions and both drains are checked.

• Check that the water runs evenly from the front as well as the rear of the wheel housing at the underside of the vehicle.
• If the water does not drain at the appropriate points, the drains must be cleaned.

Clean wind deflector:

• Check the wind deflector -1- for dirt. Especially check lower part of wind deflector for dirt -arrows-.
• Remove dirt deposits using e.g. a wet-dry vacuum cleaner .

NOTICE To remove insects and particles from the net and wind deflector frame, use a sponge and a soapy solution.

Mixing ratio for soapy solution: 3 drops of washing-up liquid to 1 litre of water.

• Then remove loose insects and particles using a vacuum cleaner with a suitable nozzle.
