Section 126 (Instrument Cluster): Speedometer: Description
A speedometer is standard equipment on all instrument clusters. The speedometer is located next to the tachometer, just to the right of center in the instrument cluster. The speedometer consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 210 degree primary scale on the gauge dial face. For all models except SRT-10 the speedometer reads left-to-right either from "0" to "120" mph, or from "0" to "200" km/h, depending upon the market for which the vehicle is manufactured. On SRT-10 the speedometer reads left-to-right either from "0" to "160" mph, or from "0" to "280" km/h, depending upon the market for which the vehicle is manufactured. Each version also has a secondary inner scale on the gauge dial face that provides the equivalent opposite units from the primary scale.
Text appearing on the cluster overlay just below the hub of the speedometer needle abbreviates the unit of measure for the primary scale (i.e.: MPH or km/h), followed by the unit of measure for the secondary scale (Fig 1 ). The speedometer graphics for all models except SRT-10 are black (primary scale) and blue (secondary scale) against a white field. On SRT-10 the gauge graphics are black (primary scale) and gray (secondary scale) against a silver field and also includes a line of text identifying this as a "Performance Vehicle Operations" product. In either case, the gauge graphics are clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting with the exterior lamps turned On, the black graphics appear blue-green and the blue or gray graphics appear light blue. The gauge needle has internal optical illumination. Gauge illumination is provided by replaceable incandescent bulb and holder units located on the instrument cluster electronic circuit board. The speedometer is serviced as a unit with the instrument cluster.
