How do you change the clock on my 1990 Mercury Cougar?

To change the clock on a 1990 Mercury Cougar, first, locate the clock or radio controls on the dashboard. Turn the ignition key to the "On" position without starting the engine. Then, press and hold the "HR" (hour) button to set the hour, and the "MIN" (minute) button to set the minutes until the correct time is displayed. Release the buttons, and the clock will be set.
