New Soft Stop Plus Door Glass Operation
August 21, 2014
The 2015 ATS coupe (Fig. 3) has a new door glass feature called Soft Stop Plus. Designed to improve door closing vibration and sound quality, the Soft Stop Plus feature allows more glass engagement to the belt line seals on door closing.
Soft Stop Plus operation is different than previous door glass operation. Express down and supervised down (holding the window switch) will both stop the glass above the belt line. (Fig. 4) The second express or supervised switch command will lower the glass below the belt line. (Fig. 5) The Comfort Open feature (pressing and holding the Unlock button on the key fob to open all windows from outside the vehicle) will stop the glass above the belt line. The window operation is the same regardless if the door is opened or closed.
TIP: The door glass will go to the full down position below the belt line every 50 cycles of the window switch to recalibrate.
It is important to remember that the door glass stopping above the belt line seals is normal. Do not replace the window regulator or adjust the glass to change this feature. There may be small differences in the glass height above the belt line when comparing the left and right sides of the vehicle. Some variation of the height also is influenced by weather and temperature conditions, which is normal and should not be adjusted.
