Chevrolet Silverado: Exterior Lighting / Auxiliary Roof-Mounted Lamp
If equipped, this button includes wiring provisions for a dealer or a qualified
service center to install an auxiliary roof lamp.

This button is on the overhead console.
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.
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 above the overhead console: a dark
green with blue stripe switched power wire and a black ground wire.
For information on roof-mounted emergency lamp installation, see www.gmupfitter.com
or contact your dealer.
If the vehicle has this button, the vehicle may have the snow plow prep package.

The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check
tire pressure levels. The TPMS sensors monitor the air pressure in your tires and
transmit tire pressure readings to a receiver located in the vehicle.
Each tire, including the spare (if provided), should be checked monthly when
cold and inflated to the inflation pressure recommended by the vehicle manufacturer
on the vehicle placard or tire inflation pressure label...
