Maintenance System

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.

Currently, predictive maintenance information is given for engine oil, transmission oil, and axle oil changes. By taking driving conditions into account, predictive maintenance provides more accurate intervals for fluid changes.

Just before the service interval ends, a message that maintenance is due will appear. See Fig..

When the service interval is reached, a pop-up notice that maintenance is due will appear with every key cycle.

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 Overdue. This cautionary pop-up will continue to appear with every key cycle.

The color of the wrench icon on the maintenance screen will change from white to amber when a maintenance service is overdue.

A service interval countdown can be reset by pressing the reset button which will cause a confirmation pop-up message to appear. If the required maintenance has been carried out, click Yes. Resetting the maintenance system when service is performed creates accurate future service intervals.

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 Detroit Connect portal. Information on the portal is updated every seven days.
