Normalize rear-end door closing control unit - AR72.20-P-7551-01TA

If a new rear-end door closing control unit is installed, it must be normalized after installation.

1. Open rear-end door with aid of rear-end door handle.

   The rear-end door requires approx. 5 s to raise and clear "relaxation" of the rear-end door is visible in the open state. The upper rear-end door is now normalized.

2. Close rear-end door with aid of rear-end door close switch (S62/35).

   The rear-end door closes completely and locks. The lower rear-end door is now normalized

3. Reprogram garage position.

   See owner's manual (opening limiter for rear-end door).
