An on-board diagnostics system tracks when regular maintenance should b done on the Mercedes Ser Van. The system triggers a "Service Soon" light that appears on the Sers dashboard display when the vehicle needs to be serviced. The great thing about the Mercedes is that you dont need any special tools to reset the warning light. However, you do need to have the Ser serviced or do the work yourself before you can manually reset and turn off the vehicles warning light.
Step 1
Put the key into the ignition and turn it to the "On" position, but dont start the engine. Look for the display between the tachometer and the speedometer on the instrument panel.
Step 2
Press the button on the lower left part of the steering wheel. The display panel will tell you why the vehicle needs servicing.
Step 3
Find and press the reset button on the left side of the instrument panel. Hold this button for three seconds.
Step 4
Press the reset button again and hold it until the display says it has been reset. Turn off the vehicle and wait 60 seconds.
Turn on the engine and verify that the service light has turned off.
Tip
- The display panel lets you know when your next service is due, based on mileage.
