Dear Prius Customer:

Thank you very much for your patronage of Toyota. We are dedicated to providing vehicles of outstanding quality and value. As part of our continuing efforts to provide superior customer satisfaction, Toyota is announcing a Special Service Campaign Program, which includes your Prius vehicle.

On certain 2004 Model Year Toyota Prius vehicles, the Hybrid Vehicle Electronic Control Unit (HV ECU) and Battery Electronic Control Unit (Battery ECU) may not conform to some portions of the diagnostic tool communication standard due to a programming error. If a repair facility's On-Board Diagnostic (OBD) scantool is used to diagnose a condition where the hybrid system warning light and/or master warning light is illuminated, the OBD scantool may not recognize the system fault.

Before you are inconvenienced by this condition, Toyota would like to reprogram the ECUs in your vehicle. Any Toyota dealer will conduct this service at NO COST to you.

Please contact your authroized Toyota dealer to make an appointment to reprogram the ECUs as soon as possible. The labor time necessary to reprogram the ECUs is approximately one hour. However, depending upon the dealer's work schedule, it may be necessary to make your vehicle available for a longer period of time. The Toyota dealer will make every effort to assure your utmost convenience during this service.

Please present this notice to the Toyota Dealer when you bring the vehicle in for your service appointment.

In order to assure your full protection under the emission warranty provisions, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could be determined as lack of proper maintenance of your vehicle.

If you no longer own the vehicle, please indicate so on the enclosed postage paid form, providing us with the name and address of the new owner.

Your local Toyota dealer would be more than happy to answer any of your questions and set up an appointment to perform the repair. If you require further assistance, you may contact the Toyota Customer Experience Center at 1-888-270-9371 Monday through Friday, 5:00 am to 9:30 pm, Saturday and Sunday 7:00 am through 3:00 pm Pacific Standard Time.

The State of California requires the completion of Special Service Campaigns on emission related parts prior to vehicle registration renewal. In addition, the State requires that every vehicle must pass an emissions test (SMOG check) every two years and before it is sold. Without the completion of this no cost Special Service Campaign, your vehicle may be more likely to fail this test. State of California regulations require Toyota to provide the Department of Motor Vehicles with a record of all vehicles that have not had the Special Service Campaign completed.

Your Toyota dealer will provide you with a Vehicle Emissions Recall Proof of Correction Form after the campaign has been completed. Please ensure you retain this form since the DMV may require that you supply proof that the campaign has been complted during your vehicle registration renewal process.

We have sent this notice in the interest of your continued satisfaction with our products, and we sincerely regret any inconvenience this condition may have caused you.

Thank you for driving the Toyota Prius.

Sincerely,
TOYOTA MOTOR SALES, U.S.A., INC.           [hybrid synergy drive logo]
