setting the clock on 05 terraza

hey does anyone know how to change the clock from a 24hr. setting to a 12 hour setting .mine is on the 24hr setting and would like to go with the 12 hour setting .the manual has not been helpful

figured out how to do it .when you press the hour button hold it down until it beeps then it will say do you want to set time . thenyou can change it to 12hr.format or 24hr.format
