When the fog lamps are turned on, the parking lamps automatically turn on. When the headlamps are changed to high-beam, the fog lamps also go off. When the high-beam headlamps go off, the fog lamps will come on again. Some localities have laws that require the headlamps to be on along with the fog lamps. The emergency roof lamp circuit is fused at 30 amps, so the total current draw of the attached lamps should be less than this value. The attachment points for the roof lamp circuits are two blunt cut wires located above the overhead console, a dark green switched power wire and a black ground wire. For further information on roof mount emergency lamp installation, please visit the GM Upfitter website at www.gmupfitters.com or contact your dealer. If your vehicle has this button, your vehicle may have the snow plow prep package. For further information see Adding a Snow Plow or Similar Equipment on page 4-41. Auxiliary Roof Mounted Lamp If your vehicle has this feature, this button includes wiring provisions for a dealer or a qualified service center to install an auxiliary roof lamp. This button is located on the overhead console. Instrument Panel Brightness D (Instrument Panel Brightness): This feature controls the brightness of the instrument panel lights and is located next to the exterior lamp control. Push the knob to extend out and then it can be turned. Turn the knob clockwise or counterclockwise to brighten or dim the instrument panel lights. Turning the knob to the farthest clockwise position turns on the dome lamps. When the wiring is connected to an auxiliary roof mounted lamp, pressing the bottom of the button will activate the lamp and illuminate an indicator light at the bottom of this button. Pressing the top of the button will turn off the roof mounted lamp and indicator. 3-19
