STATE EMISSION TESTING ADVISORY

After ECM reprogramming, the OBD system's readiness code monitors will set to "incomplete". Normally, the vehicle needs to be driven under a variety of conditions before the readiness code monitors will indicate "complete". (See State I/M Program Advisory Bulletin number 11-72-04, dated 8/4/04 for details.)

SERVICE PROGRAM IDENTIFICATION LABEL

Type or print the necessary information on a Service Program identification label. The completed label should be attached to the vehicle's upper radiator support.

Additional labels are available through the Subaru Claims Helpline at 1-866-782-2782.

CALIFORNIA "VEHICLE EMISSION RECALL - PROOF OF CORRECTION" CERTIFICATE

The California Air Resources Board and the Department of Motor Vehicles Registration/Recall Program requires that all emission related Recall/Campaign or Service Program repairs be completed before a vehicle registration is renewed. Please provide owners of vehicles registered in the state of California a completed "Vehicle Emission Recall - Proof of Correction" certificate. Vehicle owners should be advised to retain this certificate because the California Department of Motor Vehicles may require they provide proof this service program repair has been completed.

OWNER NOTIFICATION LETTER

Service Program WVT-30

Engine Control Module Reprogramming

Dear Subaru Owner:

We would like to thank you for selecting a 2011 Subaru. At Subaru, we take pride in our products and are committed to your continued satisfaction.

Subaru has developed a modification to the Engine Control Module software logic that will improve the performance of your vehicle's emission control system. This software change will not adversely affect fuel economy or performance.

WHAT WE ARE ASKING YOU TO DO PROMPTLY 

We suggest that you schedule an appointment with your Subaru Dealer as soon as possible to have your vehicle's Engine Control Module software reprogrammed. This will take approximately 40 minutes to complete. However, it may be necessary for you to leave your car longer on the day of your appointment to allow your dealer flexibility in scheduling. Your Subaru dealer will perform this modification at no cost to you.

Please present this letter to your Subaru Dealer on the day of your service appointment.

CALIFORNIA REGISTERED OWNERS 

The California Air Resources Board requires that emission related campaigns be completed prior to California's vehicle registration renewal process; without this repair, you will not be able to register your vehicle during your next annual registration. Upon completion of this campaign, your California dealer will complete and provide you a "Proof of Correction Certificate." If required, present the certificate to the California Department of Motor Vehicles (the "DMV") when renewing your California registration as proof of campaign completion. If the DMV does not request the certificate, we recommend that you keep it for your records.

In addition, the State of California requires that every vehicle must pass an emission test (SMOG Check) every two years and before it is sold. Without the free service we are providing, your vehicle may be more likely not to pass this test and require that you make costly repairs.

CHANGED YOUR ADDRESS OR SOLD YOUR SUBARU? 

If you have changed your address, or if you have sold your Subaru, please complete the enclosed prepaid postcard and mail it to us.

Sincerely,

Subaru of America, Inc.
