The auto-reverse pinch protection function is a mechanism that automatically reverses (opens) the door glass
while it is closing when the power window main switch detects the signal from the power window motor
indicating that an object is obstructing the door glass movement.
The auto-reverse pinch protection function may operate if the sliding resistance of the door glass increases
causing the closing speed to decrease.
If the door glass closing speed has changed, concentrate the inspection on the following locations: (Slip
occurrence)
Improper installation of the acrylic door visor.
Power window motor malfunction
Object caught between the glass run channel and the door glass.
Insufficient tightening of the door glass to the carrier plate.
Glass run channel malfunction.

If the door glass is slipping forward, inspect the front side of the glass guide or glass run
channel.
If the door glass is slipping rearward, inspect the rear side of the glass guide or glass run
channel.
