**PURSUANT TO GENERAL INSTRUCTION J(2) THE FOLLOWING SUBSTITUTE INFORMATION IS BEING PROVIDED IN THIS REPORT ON FORM 10-K:**

**Item 1112(b) of Regulation AB.  Significant Obligors of Pool Assets - Financial Information.**

Nothing to report. 

**Item 1114(b)(2) of Regulation AB.  Credit Enhancement and Other Support, Except for Certain Derivatives Instruments - Financial Information.**

Nothing to report. 

**Item 1115(b) of Regulation AB.  Certain Derivatives Instruments - Financial Information.**

Nothing to report. 

**Item 1117 of Regulation AB.  Legal Proceedings.**

There are no legal proceedings pending, or any proceedings known to be contemplated by governmental 

authorities, against the Sponsor, the Depositor, U.S. Bank National Association (the "Indenture Trustee"), Wilmington Trust, National Association (the "Owner Trustee"), the Issuing Entity, or any property thereof, that are material to holders of the Asset Backed Notes issued by the Issuing Entity (the "Notes"). 

**Item 1119 of Regulation AB.  Affiliations and Certain Relationships and Related Transactions.**

The Depositor is an affiliate of Mercedes-Benz Financial Services USA LLC ("MBFS"), which acts as 

Sponsor, Servicer and Administrator, in that MBFS is the sole equity member of the Depositor. 

The Sponsor acted as originator (as contemplated by Item 1110 of Regulation AB) of the receivables 

owned by the Issuing Entity and services the receivables. The Sponsor is the sole equity member of the Depositor. The Issuing Entity issued the Mercedes-Benz Auto Receivables Trust 2012-1 asset backed certificates to the Depositor and through this issuance, the Depositor has acquired a 100% ownership interest in the Issuing Entity; therefore, the Issuing Entity is an affiliated party of the Depositor and, indirectly, of the Sponsor. 

There are no significant obligors, external enhancement or support providers, or other material parties 

related to the Notes. 

In addition, there are no business relationships, agreements, arrangements, transactions or understandings 

outside the ordinary course of business or on terms other than would be obtained in an arm's length transaction with an unrelated party, apart from this asset-backed securities transaction involving the issuance of the Notes by the Issuing Entity, between the Sponsor, the Depositor or the Issuing Entity and any of the parties, or affiliates of such parties, mentioned in this Item. 

**Item 1122 of Regulation AB.  Compliance with Applicable Servicing Criteria.**

Each of the Sponsor, in its capacity as Servicer, and the Indenture Trustee (together with the Sponsor in its 

capacity as Servicer, each, a "Servicing Participant") has been identified by the registrant as a party participating in the servicing function during the reporting period with respect to the pool assets held by the Issuing Entity.  Each Servicing Participant has completed a report on an assessment of compliance with the servicing criteria applicable to such Servicing Participant (each, a "Report on Assessment") as of December 31, 2012 and for the reporting period, which Reports on Assessment are attached as Exhibits 33.1 and 33.2 to this report on Form 10-K.  In addition, each Servicing Participant has provided an attestation report (each, an "Attestation Report") by a registered independent public accounting firm on its Report on Assessment.  The Attestation Reports are attached as Exhibits 34.1 and 34.2 to this report on Form 10-K.  Neither the Indenture Trustee's Report on Assessment nor the Indenture Trustee's 

{00039010.DOCX}

3 

Attestation Report has identified any material instance of noncompliance with the servicing criteria applicable to the Indenture Trustee. 

The Servicer complied in all material respects with the servicing criteria applicable to it, except that: 

With respect to servicing criterion 1122(d)(3)(i)(A), certain reports to investors, including those to be filed with the Commission, were not filed in accordance with time frames and other terms set forth in the transaction agreements. 

With respect to servicing criterion 1122 (d)(4)(viii), certain records describing the Servicer's  activities in monitoring delinquent pool assets were not maintained as specified in the transaction agreements. 

MBFS believes that distributions to the security holders were not materially impacted as a result of the material instances of noncompliance noted above. Nevertheless, MBFS is exploring procedural and policy changes to achieve full compliance with these requirements.
