OnStar®

If the vehicle is equipped with an active OnStar system, that system may also record data in crash or near crash-like situations.

The OnStar Terms and Conditions provides information on data collection and use and is available at www.onstar.com (U.S.) or www.onstar.ca (Canada), or by pressing the Navigation System button and speaking to an advisor. See OnStar Overview on page 14‑1.
