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.

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. 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 (either mph or km/h ), followed by the unit of measure for the secondary scale.

The speedometer graphics are white (primary scale) and gray (secondary scale) against a black field making them clearly visible within the instrument cluster in daylight. When illuminated from behind by the panel lamps dimmer controlled cluster general illumination lighting, the primary scale graphics appear white and the secondary scale graphics appear light gray. The gauge needle has internal optical illumination. Gauge illumination is provided by Light Emitting Diode (LED) units located on the instrument cluster electronic circuit board.
