Reporting safety defects for U.S. owners

If you believe that your vehicle has a defect which could cause a
crash or could cause injury or death, you should immediately
inform the National Highway Traffic Safety Administration (NHTSA)
in addition to notifying Scion, a marque of Toyota Motor Sales,
U.S.A., Inc. (Toll-free: 1-866-707-2466).

If NHTSA receives similar complaints, it may open an investigation,
and if it finds that a safety defect exists in a group of vehicles, it
may order a recall and remedy campaign. However, NHTSA can-
not become involved in individual problems between you, your
dealer, or Scion, a marque of Toyota Motor Sales, U.S.A., Inc.

To contact NHTSA, you may call the Vehicle Safety Hotline
toll-free at 1-888-327-4236 (TTY: 1-800-424-9153); go to
http://www.safercar.gov; or write to: Administrator, NHTSA,
