Maintenance System
Note: the wrench icon indicates service is needed, not that something needs to be fixed.
Standard messaging is based on the number of miles (km) driven or time passed since the last service.
Predictive maintenance information is calculated based on these factors as well as engine and transmission load and oil temperature for vehicles with a Detroit engine, transmission, and axles.
Currently, predictive maintenance information is given for engine oil, transmission oil, and axle oil changes. By taking driving conditions into account, predictive maintenance can provide more accurate intervals for fluid changes.
When the service interval ends, a message that maintenance is due will appear.
The Maintenance System pop-up notice will appear with every key cycle until the system is reset.
When the service interval is overdue, the color of the wrench icon on the maintenance screen will change from white to amber and the message will change to Maintenance Due Now. See Fig.. This cautionary pop-up will continue to appear with every key cycle.

Each service interval must be reset in the maintenance system when service is performed to provide for accurate future service intervals and to turn off pop-up messaging.
The reset button for maintenance system screens will not appear until the vehicle has been driven 6.2 miles and the engine has run for fifteen minutes.
Maintenance system information and service recommendations can also be viewed in the portal. Information on the portal is updated every seven days.
