Exhibit B

Instructions

	Attribute		Instructions
	Number of Scheduled Payments		In the event the Number of Scheduled Payments in the “PCD_NBR_SCHED_PMTS” field in the Data File did not agree to the Number of Scheduled Payments listed in the respective Retail Installment Sales Contract, subtract the number of payments waived as stated in ALFA from the Number of Scheduled Payments displayed on the Retail Installment Sales Contract. In the event the payment waivers indicated in ALFA included one payment waiver for the first month and one partial payment waiver for the second month, subtract one payment from the Number of Scheduled Payments displayed on the Retail Installment Sales Contract.
	Next Payment Due Date		In the event the Next Payment Due Date in the “PCD_ACT_NEXT_SCHED_PMT_DATE” field in the Data File displayed a payment due date that is greater than the payment due date indicated in ALFA, we were informed by the Company that this was because of a prepayment made by the obligor. For such situation, we were provided by the Company with a screenshot of obligor’s payment history from ALFA to evidence such prepayment.
	FICO Score		Compare the primary buyer’s FICO Score per ACE to the FICO Score in the “PCD_FICO_SCORE” field in the Data File. If the Retail Installment Sales Contract had a co-buyer listed and the primary buyer’s FICO Score in ACE was “NA,” utilize the FICO Score of the co-buyer on the Retail Installment Sales Contract to compare FICO Score in the “PCD_FICO_SCORE” field in the Data File.
	Sold Code Indicator		Consider the Sample Receivable to be in agreement if the “Securitization Pool Number” field in the “Miscellaneous” screen in ALFA was not populated (i.e., blank) and the “PCD_SOLD_CODE” field in the Data File was blank.
	Recovery Indicator		Consider the Sample Receivable to be “Live” if the term “Live Schedule” was next to the account number in ALFA.
	Vehicle Manufacturer		Compare the Vehicle Manufacturer in the Retail Installment Sales Contract to the Vehicle Manufacturer listed in the “PCD_MAKE” field in the Data File. Consider variations due to spelling, abbreviation, or truncation of the full Vehicle Manufacturer to be acceptable, to the extent such variation refers to “Mercedes-Benz.” In the event there was not an acceptable variation of the Vehicle Manufacturer in the Retail Installment Sales Contract, compare the vehicle make listed in the VIPS 2.0 to the Vehicle Manufacturer listed in the “PCD_MAKE” field in the Data File.
	Vehicle Model		In the event the Vehicle Model in the “PCD_MODEL” field stated in the Data File did not agree with the Vehicle Model in the Retail Installment Sales Contract, compare the vehicle model listed in the VIPS2.0 to the Vehicle Model listed in the “PCD_MODEL” field in the Data File.

	Attribute		Instructions
	Original First Payment Date		In the event the Original First Payment Date in the “PCD_SCHED_FIRST_PMT_DATE” field stated in the Data File did not agree to the Original First Payment Date listed in the respective Retail Installment Sales Contract, Modification Letter, or ALFA, add the number of months waived as stated in ALFA to the Original First Payment Date in the Retail Installment Sales Contract or Modification Letter.
	Subvented		Consider the Sample Receivable to be “Subvented” if the (i) “Subsidy Code” field was populated (i.e. not blank) in the “Miscellaneous” screen in ALFA, and (ii) an “Accounting Event – Expense Type” of “Manufact. Subsidy (rate/residual)” listed an amount greater than $0 in the “Other Payments” screen in ALFA.
	Interest Paid through Date		In the event the Interest Paid Through Date in the “PCD_INT_PAID_THRU_DTE” field stated in the Data File did not agree with the Interest Paid through Date listed in the ALFA, compare the date of the last payment before the Cutoff Date in ALFA to the date in “PCD_INT_PAID_THRU_ DTE” field in the Data File.
	Payment to Income Ratio		Recompute using the “Monthly Payment Amount” in the Retail Installment Sales Contract divided by the “Monthly Obligor Income” in ACE. In the event the “Co-obligor Present Indicator,” in ACE, was denoted with a “1,” we were instructed by the Company to sum the monthly income amount from the “Monthly Obligor Income” and “Monthly Co-obligor Income” in ACE.
