Chevrolet Silverado: Warning Lights, Gauges, and Indicators / Charging System Light

The charging system light comes on briefly when the ignition is turned on, but
the engine is not running, as a check to show the light is working. It should go
out when the engine is started.
If the light stays on, or comes on while driving, there may be a problem with
the electrical charging system. Have it checked by your dealer. Driving while this
light is on could drain the battery.
When this light comes on, or is flashing, the Driver Information Center (DIC)
also displays a message.
If a short distance must be driven with the light on, be sure to turn off all
accessories, such as the radio and air conditioner.
The vehicle has a passenger sensing system. See Passenger Sensing System 0 75
for important safety information. The overhead console has a passenger airbag status
indicator...
This light is part of the vehicle’s emission control on-board diagnostic system.
If this light is on while the engine is running, a malfunction has been detected
and the vehicle may require service...

Warning
Cruise control can be dangerous where you cannot drive safely at a steady
speed. Do not use cruise control on winding roads or in heavy traffic.

changes in tire traction can cause excessive wheel slip, and you could lose control...
If equipped, Active Fuel Management allows the gasoline engine to operate on
either all of its cylinders, or a reduced number of cylinders, depending on the
driving conditions. When less power is required, such as cruising at a constant
vehicle speed, the system will enable reduced cylinder operation, allowing the vehicle
to achieve better fuel economy...
