Fuel Gauge: Description and Operation
Description
DESCRIPTION
A fuel gauge is standard equipment on all instrument clusters. This gauge is located on the left side of the instrument cluster, just left of the speedometer.
This gauge consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 90 degree gauge scale on the cluster
overlay that reads left-to-right from E (or Empty) to F (or Full).
An International Control and Display Symbol icon for Fuel is located on the cluster overlay, directly above the hub of the gauge needle. An arrowhead
pointed to the left side of the vehicle is imprinted on the cluster overlay next to the Fuel icon on the gauge to provide the driver with a reminder as to the
location of the fuel filler access. On SRT8 vehicles, text that specifies PREMIUM ONLY is located across the fuel gauge below the gauge scale, but
above the Fuel icon.
On all vehicles the fuel gauge graphics are gray and white against a black field except for two red graduations at the low end of the gauge scale.
In all Laredo vehicles, 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 white text and graphics still appear white, the gray graphics still
appear gray and the red graphics still appear red. The red gauge needle has internal optical illumination. Gauge illumination is provided by Light
Emitting Diode (LED) units soldered onto the instrument cluster electronic circuit board.
In all vehicles except Laredo, the gauge graphics are nearly invisible within the instrument cluster in daylight while the ignition switch is in the OFF
position. When the ignition is turned ON the gauge is illuminated from behind at full brightness by the cluster illumination lighting. The white text and
graphics still appear white, the gray graphics still appear gray and the red graphics still appear red. The white gauge needle has internal optical
illumination. With the exterior lamps turned ON, the cluster illumination lighting is panel lamps dimmer controlled. Gauge illumination is provided by
LED units soldered onto the instrument cluster electronic circuit board.
The fuel gauge is serviced as a unit with the instrument cluster.
