This morning when I started my car, there were 26 miles of cruising range stated on the trip computer and the gas gurage was point a mark above E. My officer is 2 miles away and the outside temperature was 10 - 15F. When I was less than a mile away from the office, my cruising range was still around 23. After a stop sign, when i look down, it dropped to 0............and my gas gurage was pointing to E.

I was thinking it is because of the acceleartion which affects the MPG, which then affect the Cruising range calculation. However my light acceleration will not be that effective that can lower my cruising range from 20 to 0.

Any suggestions or comments?

Thanks .
Ian
