2012 R350 tailgate opening angle programming
I've tried to follow the menu to program the opening angle of the tailgate by
1. lift the handle, the tailgate start opening
2. press the stop bottom in the tailgate when the angle is reached
3. press and hold the stop bottom try to set the default and expecting a short tone as menu described but nothing happen. (how long do I need to press and hold? I have tried up to 20 sec but not able to make it)
Did I miss anything? I have tried to re-do the 1-3 with engine started, or just the ignition on but nothing seems to be able to get that "short tone" as indication of success?
Thank you so much for the help. Really appreciated.
From max opening of the tailgate to about 2 inches down from the max height, the tailgate cannot be saved at in that range. Any other range from 2 inches down to half (or lower since I didn't try any lower) is saved by stopping the tailgate and holding down the close tailgate button until you hear the chime.
It is unfortunate it was designed this way as max height slightly brushes against my garage door, but the first angle you may save it at doesn't allow me to stand up straight while under the tailgate
