This bulletin is being revised to update the model years, models and parts information. Please discard Corporate Bulletin Number 00-08-46-002 (Section 08 -- Body & Accessories).

Replacement parts for the OnStar® system cellular antenna are available as follows:

• | Cellular Antenna Kit -- If the antenna mast or exterior base is damaged or missing or if the antenna base has separated from the exterior glass surface.

• | Cellular Antenna Inner Coupling -- If the antenna coupling on the inside of the glass requires replacement.

Important: If glass replacement is required, both the Cellular Antenna Kit and the Cellular Antenna Inner Coupling are required.

The kits listed contain all the necessary parts and instructions needed to properly install a new cellular antenna exterior base or interior coupling to the glass surface. To obtain maximum adhesion during installation, the instructions included in the kits must be followed carefully and exactly as written.

Important: Do not attempt to reinstall the original cellular antenna exterior base or interior coupling using any type of glue, adhesive tapes, etc. Doing so may eliminate the cellular signal transfer through the glass and reduce the maximum performance of the system that includes air bag deployment notification.

Important: To obtain maximum adhesion between the new cellular exterior base or interior coupling and the glass surface, the base, coupling and glass must be kept dry and above 15° C (60° F) during the installation and for the 24 hours immediately following the installation. Not keeping the vehicle dry and above the temperature listed for 24 hours may result in the new cellular antenna exterior base or interior coupling coming off.
