Insert the key and start the vehicle to power it on. Hold down the CL button for 3 seconds. The first digit of the clock from the left will start flashing. Use the buttons below to adjust the digit (cycling through 0-9) to the desired number. Press the CL button once more, and the second digit will start flashing. Adjust it to the desired number using the digit buttons. Press the CL button again, and the third digit will start flashing. Adjust it to the desired number using the digit buttons. Finally, hold down the CL button for 3 seconds to confirm the settings.
I've been driving the older Mercedes-Benz B-Class for years and adjusting the time is second nature to me. Locate the round button or small knob near the instrument cluster, usually labeled 'Set' or 'Menu', and hold it down for two to three seconds until the menu options appear on the screen. Then use the directional buttons or knob to scroll to the 'Clock Setting' option and select it. Use the plus and minus buttons to adjust the hours and minutes, making sure to confirm the AM/PM setting is correct to avoid confusion. Once done, press the 'OK' button to save. I adjust it every quarter for daylight saving time to prevent navigation issues. Another tip: if the buttons don't respond, it might be a loose fuse in the instrument cluster—check the manual to locate and tighten it. Also, after a battery replacement, the time will reset, so you'll need to adjust it again—no need to panic. For safety, it's easiest to do this when the car is parked and turned off.
As someone who frequently repairs cars, I've dealt with many timing issues on older Mercedes-Benz B-Class models. The crucial first step is ensuring the electronic system is functioning properly: turn the ignition switch to the ON position without starting the engine, then locate the button cluster on the center console. Hold down the Mode button until the menu pops up, and select the time setting option. Use the directional control knob to adjust the numbers, and press confirm once set. If the buttons don't respond, it might be due to a blown fuse or a short circuit; try removing the fuse for 5 minutes and reinserting it to reset. Inaccurate time can sometimes be caused by voltage fluctuations from the alternator, so it's advisable to use a multimeter to check for stable voltage. During operation, avoid rushing the button presses and proceed step by step. After completion, check if the dashboard displays the time synchronously. Regularly adjusting the time can help prevent minor issues with the instrument panel.
