With an active OnStarĀ® subscription with personal calling, telephone calls can be made from the vehicle, using the navigation system screen to enter the numbers.

(Place/End Call): Touch to place the phone call. While in a call, this button is red. Touch this button to end the call.

Tone Send: Touch to send touch tone data. This button is available during a phone call. This function is used when numbers in response to an automated phone request need to be entered, such as when checking voice mail or when asked to choose menu items.

Incoming Call: When receiving an incoming call, a pop-up message displays on the screen with two place/end call screen buttons, one green and the other red. Touch the green button to answer the call. Touch the red button to reject the call.

When using the OnStarĀ® system, the audio system mutes. The volume of an OnStarĀ® call can be adjusted by using the steering wheel controls or the volume knob on the navigation system. See "OnStarĀ® System" in the Index of the vehicle's owner manual for more information.
