Maintenance Indicator: Description

WARNING: This page is about a different car, the 2006 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.

An Active Service System (ASSYST) engine oil maintenance indicator is optional equipment on all instrument clusters. In vehicles so equipped, a second, dedicated ASSYST microprocessor is integral to the cluster electronic circuit board. The ASSYST indications are displayed and can be toggled with the clock indication on the right side of the multi-function indicator Liquid Crystal Display (LCD) located near the lower edge of the instrument cluster, directly below the speedometer. The ASSYST displays include numeric values combined with several icons to indicate actual engine oil level, and reminders in time (days) or distance (miles or kilometers) until the next required engine oil maintenance is anticipated. ASSYST also provides several audible indications using the electronic tone generator on the instrument cluster circuit board to supplement these visual displays.

The indications of the ASSYST engine oil maintenance indicator are not visible when the LCD is not illuminated. When illuminated, the ASSYST indications appear as dark characters and icons silhouetted against an amber field. When the exterior lighting is turned Off, the display is illuminated at maximum brightness. When the exterior lighting is turned On, the display illumination level can be adjusted in concert with the cluster general illumination lighting using the "+" (plus) and "-" (minus) multi-function indicator push buttons. The ASSYST engine oil maintenance indicator is serviced as a unit with the instrument cluster.
