Transmission Range Indicator - Description

DESCRIPTION

An electronic automatic transmission gear selector indicator is standard factory-installed equipment on this vehicle. However, on vehicles not equipped with an optional automatic transmission, this indicator is electronically disabled. The gear selector indicator information is displayed in the upper left corner within the fixed segment Organic Light Emitting Diode (OLED) display unit. This OLED display unit is soldered onto the cluster electronic circuit board, and is visible through a window with a smoked clear lens located on the lower edge of the speedometer dial face of the cluster overlay. The dark lens over the OLED display unit prevents the indicator from being clearly visible when it is not illuminated.

The gear selector indicator displays the following characters from left to right: P, R, N, and a fourth, reconfigurable character. The reconfigurable character can be a letter D or the numbers 1 through 4. Each character appears in a white color and at the same lighting level as the odometer information. Respectively, these characters represent the PARK, REVERSE, NEUTRAL and each of the forward drive gear positions of the transmission gear selector lever on the floor panel transmission tunnel. The indicator also illuminates brackets [ ] on each side of the character that represents the currently selected lever position.

During daylight hours (exterior lamps are OFF) the fixed segment OLED is illuminated at full brightness for clear visibility. At night (exterior lamps are ON), the OLED lighting level is adjusted with the other cluster general illumination lamps using the panel lamps dimmer function of the interior lighting control sleeve on the left multi-function switch control stalk. However, a PARADE mode position of the control sleeve allows the OLED to be illuminated at full brightness if the exterior lamps are turned ON during daylight hours.

The gear selector indicator is serviced as a unit with the fixed segment OLED display unit in the instrument cluster.
