Four Low Mode Indicator
A four low mode indicator is standard equipment on all instrument clusters. See Fig 1. However, on vehicles not equipped with the optional four-wheel drive system, this indicator is electronically disabled. This indicator is located above the coolant temperature gauge and to the right of the tachometer in the instrument cluster.
The four low mode indicator consists of a stencil-like cutout of the words "4 LO MODE" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not illuminated. An amber Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the "4 LO MODE" text to appear in amber through the translucent outer layer of the overlay when the indicator is illuminated from behind by the LED, which is soldered onto the instrument cluster electronic circuit board.
When the exterior lighting is turned On, the illumination intensity of the four low mode indicator is dimmable, which is adjusted along with the cluster illumination lighting using the panel lamps dimmer control ring on the left control stalk of the multi-function switch. The four low mode indicator is serviced as a unit with the instrument cluster.
