Small black "knob" between my fuel gauage and temp gauge
Thanks to everyone for answering my questions about my S. Yes, I have another question.
There is a small black "knob" between my fuel gauage and temp gauge. Turning it does nothing. There is also not mention of it (or its function) in the manual. I thought it would reset the miles traveled back to zero in order to manually calculate the MPGs. What does it do? TIA
So far I've gone about 150 miles (rush hour freeway driving) on a 1/4 tank of gas. My 98 Escort wagaon would be between 1/2 and 3/4 at this point.
