I just had the battery replaced in my 2016 Mazda CX-5, and now some electrical things aren’t working such as the auto-down feature on the driver’s side window. Any advice on how to restore these functions? Thanks. ---

Two things 1. Look on your menu program for settings 2. You still under warranty . ---

The owners manual explains how to initialize the power window, it is routine after disconnecting the battery. **Power window system initialization** **procedure** If the battery was disconnected during vehicle maintenance, or for other reasons (such as a switch continues to be operated after the window is fully open/closed), the window will not fully open and close automatically. The power window auto function will only resume on the power window that has been reset. 1 Switch the ignition ON. 2 Make sure that the power window lock switch located on the driver’s door is not depressed. 3 Press the switch and fully open the window. 4 Pull up the switch to fully close the window and continue holding the switch for about 2 seconds after the window fully closed.
