Official summary
This service information bulletin provides a procedure for customizing the maintenance period settings of the MFD. When accessing the maintenance period information on the SSM4, the maintenance interval default values for mileage and number of months are different from those displayed on the MFD. This procedure describes how to synchronize the MFD and SSM4 values to insure proper customer notification.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
