RAM 3500 Truck 4WD L6-6.7L DSL Turbo (2008)
A 4WD indicator is standard equipment on all instrument clusters. However, on vehicles not equipped with an optional four-wheel drive system, this
indicator is electronically disabled. The 4WD indicator is located on the right side of the instrument cluster, to the right of the oil pressure gauge.
The 4WD indicator consists of a stencil-like cutout of the text 4WD 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 indicator to appear in amber through the translucent outer layer of the overlay when it 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 4WD indicator is dimmable, which is adjusted along with the cluster general
illumination lighting using the panel lamps dimmer thumbwheel on the headlamp switch.
The 4WD indicator is serviced as a unit with the instrument cluster.
4 Low Indicator
4 LOW INDICATOR
A 4 low indicator is standard equipment on all instrument clusters. However, on vehicles not equipped with the optional four-wheel drive system and
electronically shifted transfer case, this indicator is electronically disabled. The 4 low indicator is located on the right side of the instrument cluster, to
the right of the coolant temperature gauge.
The 4 low indicator consists of a stencil-like cutout of the text 4 LOW 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 indicator to appear in amber through the translucent outer layer of the overlay when it 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 4 low indicator is dimmable, which is adjusted along with the cluster general
illumination lighting using the panel lamps dimmer thumbwheel on the headlamp switch.
The 4 low indicator is serviced as a unit with the instrument cluster.
