Nissan Altima: Auto-reverse function
If the control unit detects something caught in the window as it is closing, the window will be immediately lowered.
The auto-reverse function can be activated when the window is closed by automatic operation when the ignition switch is placed in the ON position or for 45 seconds after the ignition switch is placed in the OFF position. Depending on the environment or driving conditions, the auto-reverse function may be activated if an impact or load similar to something being caught in the window occurs.
There are some small distances immediately before the closed position which cannot be detected. Make sure that all passengers have their hands, etc., inside the vehicle before closing the window.
