The initial odometer reading is entered at the time of install, and updates automatically as the vehicle is driven. However, a small amount of drift from the vehicle's odometer reading is to be expected as the system calculates the odometer using GPS information.
1) Navigate to the Admin->Vehicle Admin page and select the Vehicle you wish to update
2) Select the Maintenance Tab at the top
3) On the right side of the screen find 'Vehicle Usage' and click 'Update' for the Reported Odometer
Note: If you do not see the 'Update' button in the Vehicle Table, you might not have high enough privileges to edit vehicle information. You will need to have a user with Admin level access make these changes, or elevate your privileges per this guide
2) Select the Vehicle you wish to update from the Table, and select 'Edit'
