My odometer reads "ERR" and then the miles. What is wrong ?

You'll have to use the tenths on the trip odometer.

Here is an example of miles to kilometers

mi -> kmkm = mi * 1.6093km = 107.098 * 1.6093km = 172.36
or kilometers to miles
km -> mimi = km _______ 1.6093mi = 107.098 ________ 1.6093mi = 66.548

there should be a button on the dash or under the speedometer

Are you looking at the odometer or the tripometer? If it only has 5 digits it does not read the tenths of a mile only whole miles. So just read it as milage like 10 miles not 1.0 miles.

change the whole instrument cluster with one from a wreck.

Problem is in the guage cluster assy.The ODO is mechanical,serviced by replacing guage cluster.

I had the same problem and was about to take the car to the dealership tomorrow, but I decided to try disconnecting the battery and see if it would reset itself. When I reconnected the battery the odometer mileage went back to where it was before I changed the battery. It worked!

Maybe it will work for you. Good luck!

there is a button on the dash, it says ENGLISH/METRIC, push it.

okay,for one,the odometer doesnt read in miles per hr,it reads miles driven, and two i have no idea if its possible to change the odometer to km traveled,if you're talking about the speedometer,its already there,get a european cluster :p
