2004 Mercedes Benz C230 6 cyl Front Wheel Drive Automatic 70,000 miles
My friend performed the series A tune up but the light did not go off and he's out of town now for a month. Can you please tell me how to turn off the warning light? Thank you so much in advance for your assistance. Kari
Turn the key to position 2 (position right before ignition when all dash lights are on). Now scroll to the A Service screen. Now hold the trip reset button on the left of the instrument cluster until the service reminder resets. This should take no more than 20secs.
