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 more information on roof mount
emergency lamp installation, please
visit the GM Upfitter website at
www.gmupfitters.com or contact
your dealer.
If the vehicle has this button, the
vehicle may have the snow plow
prep package. For further

the exterior lamps control.
Push the knob to extend out and

The cargo lamps come on by
turning the instrument panel
brightness control knob to the

lamps.
The cargo lamps can be used if
more light is needed in the cargo
area of the vehicle or in the top-box
storage units.
Dome Lamps
The dome lamps come on when any
door is opened. They turn off after
all the doors are closed.
The dome lamps can also be turned
on by turning the instrument panel
brightness knob, located on the
instrument panel to the left of the
