The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

When using the OnStar voice recognition dialing, some numbers and/or commands may not be understood by the system, especially the number two (2).

Recommendation/Instructions:

If the OnStar system properly responds to any command, the hardware is assumed to be good and the customer should be directed to the description and operational characteristics published in Service Information (SI) and the Owners Manual. They may also be directed to contact OnStar and be connected with Onstar customer care for assistance with system operation and tips.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
