Policies And Procedures
New and Used Vehicles in Dealership Inventory (In-Stock Vehicles)
To ensure customer satisfaction, Toyota requests that dealers complete this Special Service Campaign on any
new or used vehicles currently in dealer inventory that are covered by this Special Service Campaign prior to
customer delivery. However, if the campaign cannot be completed (for example, due to remedy parts
availability), delivery of a covered vehicle is acceptable if disclosed to the customer that the vehicle is involved
in a Special Service Campaign.
Toyota expects dealers to visit https://toyota-recall-disclosure.imagespm.info/ and complete a Customer
Contact and Vehicle Disclosure Form. Dealers are expected to provide a copy of the completed form, along
with the most current FAQ, to the vehicle buyer. Toyota and the dealer may use this information to contact the
customer when the remedy becomes available. Keep the completed form on file at the dealership.
NOTE: Dealers can identify if any of their new and used inventory has any open campaigns in the Vehicle
Inventory Summary available in Dealer Daily (Non SET and GST dealers: https://dealerdaily.toyota.com/). The
Vehicle Inventory Summary may take up to 4 hours to populate information for newly launched campaigns.

Toyota Certified Used Vehicle (TCUV)
The TCUV policy prohibits the certification of any vehicle with an outstanding Safety Recall, Special Service
Campaign, or Limited Service Campaign. Thus, no affected units are to be designated, sold, or delivered as
a TCUV until all applicable Safety Recalls, Special Service Campaigns, and Limited Service Campaigns have
been completed on that vehicle.
Claim Filing Accuracy and Correction Requests
It is the dealer’s responsibility to file claims correctly for this Special Service Campaign. This claim filing
information is used by Toyota
for various government reporting activities; therefore, claim filing accuracy is
crucial. If it has been identified that a claim has been filed using an incorrect Op Code or a claim has been
filed for an incorrect VIN, refer to Warranty Procedure Bulletin PRO17-03 to correct the claim.
Parts Recovery Procedures
All parts replaced as part of this Safety Recall must be turned over to the parts department until appropriate
disposition is determined. The parts department must retain these parts until notification via the Parts
Recovery System (PRS) is received indicating whether to ship or scrap the parts. These parts are utilized by
various departments for defect analysis, quality control analysis, product evaluation, as well as other
purposes.
To help minimize dealer storage challenges, Toyota
recommends that dealers:
• File the campaign claim accurately and promptly. The time a dealer is required to hold parts is based on
when the campaign claim is paid by Toyota.
• Monitor the Warranty Parts Recovery Notifications and Part Scrap Report regularly.
Refer to Warranty Policies 9.3 and 9.6 for additional details.
