Section 531 (Instrument Cluster): Speedometer: Description
A speedometer is standard equipment on all instrument clusters. The speedometer is located next to the tachometer, just to the left 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 255 degree primary scale on the gauge dial face that reads left-to-right either from "0" to "120" mph, or from "0" to "240" km/h, depending upon the market for which the vehicle is manufactured.
Most versions also have a secondary inner scale on the gauge dial face that provides the equivalent opposite measurement units from the primary scale. Text appearing on the cluster overlay just above the hub of the speedometer needle abbreviates the unit of measure for the primary scale (i.e.: MPH or km/h), while the text for the unit of measure for the secondary scale (i.e.: MPH or km/h) is located adjacent to the low end of that scale. See Fig 1.
The speedometer primary scale text is white against a black field, while the major and minor primary scale increments are black against a silver field. If equipped, the secondary scale text and increments are light gray against a black field. All text and increments 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, all primary scale text and major increments appear blue-green. The primary scale minor increments and the secondary scale are not illuminated. The red gauge needle is internally illuminated.
Gauge illumination is provided by replaceable incandescent bulb and bulb holder units located on the instrument cluster electronic circuit board. The speedometer is serviced as a unit with the instrument cluster.
