ADR 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.

A constant engine speed (ADR) indicator is standard equipment on all instrument clusters, but is only functional on vehicles equipped with the optional ADR switch. The ADR indicator is located near the lower edge of the instrument cluster, to the right of the multi-function indicator display. The ADR indicator consists of the text "ADR" imprinted within a rectangular cutout in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not illuminated. An amber Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the text to appear silhouetted against an amber field through the translucent outer layer of the overlay when the indicator is illuminated from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The ADR indicator is serviced as a unit with the instrument cluster.
