Adjusting Cabriolet convertible top







1. Adjusting Cabriolet convertible top
The assembly aids must be recalibrated after removal or after an accident repair in the area of the side section on the inside.

The calibration of the assembly aids represents the basic position for convertible top installation. The required tools include a tape measure and a rule or an aluminium section at least 1600 mm long, which is laid over the rear side sections, front centre, first Roof Transport System fastening hole.

Dimension -A = 135 mm- is measured from the rear side parts to the assembly aid, centre of peg on the rear side section on the inside.


NOTE:
- Dimension -B- is only applicable until model year 2002.
- As of model year 2003 the dimension -B- is omitted, the assembly aid -1- is replaced by assembly aid -2-.
- The new assembly aid -2- is positioned by pressing it in until it engages in the fastening point.

Dimension -B = 118 mm- is measured from the upper fastening point, centre of hole for convertible-top support (rear side part on inside), to the assembly aid.

Dimension -C = 1064 mm- is measured from centre of assembly aid peg to lower edge of convertible-top peg housing on inside.


2. Adjusting convertible-top peg housing

In order to avoid rattling noises, each of the convertible-top peg housings on the left and right must be facing outwards in relation to the centring pins fitted on the convertible top or hardtop when tightening.

NOTE: The convertible top must be closed or the hardtop must be fitted to check the adjustment.

3. Check dimension on convertible top after calibrating the assembly aids

After calibration of the assembly aids and fitting of the convertible top with convertible top closed, the check dimension from the styling edge, roof frame 1, lower edge diagonal to styling edge, roof frame 3, upper edge, rear should be -E = 1024 ± 2 mm-.







4. Adjusting the tension cables on the adjusting piece

The tension put on the tensioning bow by the left and right tension cables braces the convertible-top covering and presses the tension bow seal against the convertible-top compartment lid. If the pressure of the tension bow seal is too great, the convertible-top compartment will project with respect to the lid and the side part.







Adjustment procedure: Raise the convertible-top compartment lid to upper position. Adjust tension of the tension bow at the hexagon-head bolt in the adjusting piece on the roll-over bar (adjustment range approx. 15 mm) according to the lid and side-part contours and the contact pressure on the convertible-top compartment lid.

Checking the adjustment: Clamp a paper strip between the convertible-top compartment lid and tension bow seal; when the convertible top is closed, it should not be possible to pull out the sheet of paper.


NOTE: On vehicles that were operated for an extended period with the convertible top open or with a hardtop, the centring pins of the roof frame and the locking hook might not engage in the windscreen frame the first time the convertible top is closed. It is necessary to provide manual assistance at the hand hold on the convertible-top latch. The folded convertible-top covering must first stretch again.


5. Adjusting the convertible top resting position
With the convertible top open, the corner bow rests on the adjusting piece in the water collection tray. The adjusting piece can be vertically adjusted by approx. 30 mm by screwing the adjusting piece in or out. A corner bow that is set too low can leave pressure marks in the plastic window.

Adjustment procedure: Adjust height at the adjusting piece so that the convertible-top compartment lid can still close freely.
