When an obstacle has been detected in the window opening as the window is moving upward, the window will automatically reverse direction and move down. This is known as “bounce-back”. If the ignition is turned off (without accessory delay being active) during bounce-back, the window will move down until the bounce-back position is reached.

Security override

To override a bounce-back condition, within two seconds after the window reaches the bounce-back position, pull and hold the switch up and the window will travel up with no bounce-back or pinch protection. If the switch is released before the window is fully closed, the window will stop. For example, this can be used to overcome the resistance of ice on the window or seals.
