How to Set a Clock on a Cadillac Deville

by Leonardo R. Grabkowski

The last model of the Cadillac Deville was produced for the 2005 model-year. For 2006, the Deville was replaced by the Cadillac DTS, a very similar vehicle. If you need to set the clock on your Cadillac Deville, you can do so with the keys in or out of the ignition. You'll need to set the clock for seasonal time changes or if the battery is replaced or disconnected.

Step 1

Locate the "HR" and "MN" buttons on the right side of the radio's interface. "HR" is on top; "MN" is on the bottom.

Step 2

Push either the "HR" or "MN" button once to display the time on the radio screen.

Step 3

Select then depress the "HR" button. You'll notice that the hour begins to advance. Release the "HR" button when the hour is correct.

Push and hold the "MN" button. The minute will begin to advance. Release it when the minutes are correct.


  • You can also synchronize your Cadillac Deville's clock radio with the time broadcast by an FM radio station--if your radio has an "RDS" label in the upper-left corner. To do this, turn your radio on and tune into any station. Press and hold "HR" and "MN" until the interface shows "Time Updated."
