Volume Control: You can control the volume of the OnStar System using either the volume knob on the radio or, if equipped, the steering wheel volume controls. (Telltale Light): This light will indicate the status of the system. A solid green light will come on when you start the vehicle to let you know that the system is on and is ready to make or receive calls. If the light blinks green, it means that an incoming or outgoing call is in progress. Press the Communication button if you notice the light blinking and you are not on a call. The light will be red in the event of an OnStar system malfunction. If this occurs press the OnStar Services button to attempt to contact an advisor. If the connection is made, an advisor will assist you with steps to take to make sure that the system is functioning properly. If you cannot contact the advisor, take your vehicle to your dealership as soon as possible for assistance. 2-63
