• In response to an official request by the police, a court of law or a government agency
• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle
owner
● Usage of data collected through Safety Connect / Lexus Enform (U.S. mainland

If your Lexus has Safety Connect or Lexus Enform and if you have subscribed to
those services, please refer to the Safety Connect / Lexus Enform Telematics Sub-
scription Service Agreement for informat ion on data collected and its usage.
