Hello everyone! Today, you will learn how to adjust the time on a 2005 Mercedes C-Class W203 and other Mercedes models sold during the same years. Turn on the instrument cluster but not the engine (it's not necessary), then turn on the onboard computer / radio.

Using the radio, press the "serv" button clearly shown in the video, then click on "system" and "time". Use the arrows located at the bottom and right to adjust the hours and minutes. As you can see, this is a very simple, quick operation that anyone can do. Turn off the cluster and turn it back on for a final check.

Good luck!
