How do you change the hour on your clock up or down on your 2002 Mazda mpv?

To change the hour on your 2002 Mazda MPV clock, press and hold the "H" button (for hour) until the display starts blinking. Then, use the "H" button to adjust the hour up or down as needed. Once you’ve set the correct hour, press the "H" button again to save the setting and exit the adjustment mode. If your model has a separate minute button, you can adjust the minutes in a similar manner.
