In 2006 through 2013 Mercedes-Benz S-Class W221, you may be unable to set or synchronize the clock on the dashboard. In this guide, we go over a few different tips and tricks that can help you set the clock.

There are a few different ways to set the clock on a W221 S-Class, even if the clock refuses to change.

Method 1 – Easy & Simple

Press and hold the CD eject button until the system resets.

Once you see the COMAND reboot, you have about 1 minute to change the clock in standard system settings. Go to the vehicle on your screen and see the settings.

Method 2 – Permanent Solution

Perform COMAND software updates. You can update yourself by following this guide (free) or consult the dealership (cost money). Once the update is performed, you can change the clock at any time.

Method 3

Try to set the clock first thing in the morning when you get into the car before starting the engine. (Ignition on, no start)

Method 4

Disconnect the battery in the boot for a short while; then, you could reset it on the command within a minute.

Method 5

Remove one of the battery terminals before midnight and reconnect strictly at noon, midday, or midnight. Whether you do it at noon or midnight, it doesn’t matter.

Method 6

Change the language to German; then, you can set the clock. After you set the clock, change the language back to English.
