I need to reset my settings after changing the oil on my Mercedes 240C. I am not sure how to do that. I would appreciate a some help with this]

 

Easy... With the ignition on but the car not running, use the paging controls on the steering wheel until you get to the service interval reminder (the wrench). Then depress and hold the reset button (to the left of your insrument cluster) until it asks you if you want to reset the service interval. Pressing the button again will reset the light.
