If you push the end of the right hand stalk (washer control) it toggles through the three displays shown on your screen The first one is a symbol of a car showing mileage available on fuel left, average miles per gallon and distance to destination if set. Next is 1 showing mileage done since reset- average mpg - average speed. Most people use this between fill ups. You reset this by depressing and holding in the end of the stalk while on this setting. Next is 2 the same as above, I have not touched this since getting my car, so it shows me mileage done - average mpg and average speed since new. Again this can be reset in the same manner. I hope this helps Keith
