• Attach the documentation to the pre-approval request.
• If approved, submit a ‘based on claim’ for the pre-approval.
• The Dealer is required to reimburse the customer the appropriate amount.

IMPORTANT: OWL must be viewed prior to performing the Field Service campaign to ensure the vehicle is involved and
the campaign has not been previously completed. Also check for a completion sticker prior to beginning work.
U.S. and Canadian dealers, if you have any questions, contact the Warranty Campaigns Department by submitting an
inquiry through the Prism Network Assist (PNA) at DTNAPortal.com/PNA. Export distributors, submit a ticket via the Prism
Network Assist (PNA) at DTNAPortal.com/PNA, or contact your International Service Manager.
U.S. and Canadian Dealers: To return excess kit inventory related to this campaign, U.S. dealers must submit a Parts
Authorization Return (PAR) to the Memphis PDC. Canadian dealers must submit a PAR to their facing PDC. All kits must
be in resalable condition. PAR requests must include the original purchase invoice number. Export Distributors: Excess
inventory is not returnable.
The letter notifying U.S. and Canadian vehicle owners is included for your reference.
Please note that the National Traffic and Motor Vehicle Safety Act, as amended (Title 49, United States Code, Chapter
301), requires the owner’s vehicle(s) be corrected within a reasonable time after parts are available to you. The Act states
that failure to repair a vehicle within 60 days after tender for repair shall be prima facie evidence of an unreasonable time.
However, circumstances of a particular situation may reduce the 60-day period. Failure to repair a vehicle within a
reasonable time can result in either the obligation to (a) replace the vehicle with an identical or reasonably equivalent
vehicle, without charge, or (b) refund the purchase price in full, less a reasonable allowance for depreciation. The Act
further prohibits dealers from selling a vehicle unless all outstanding recalls are performed. Any lessor is required to send
a copy of the recall notification to the lessee within 10 days. Any subsequent stage manufacturer is required to forward
this notice to its distributors and retail outlets within five working days.
