SummaryIn our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA (“MBUSA”) is extending the coverage for the change-over valve on your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 10 years / 120,000 miles (whichever occurs first), and applies to the vehicle regardless of ownership. Why the warranty extension? On certain Model Year 2016-2017 smart vehicles, the change-over valve which is responsible for the operation of the heating shut-off valve within the coolant circuit, could corrode internally due to water intrusion. The internal corrosion might then prevent proper operation of the heating shut-off valve. Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz smart dealership. • If your preferred authorized Mercedes-Benz smart dealership performs a diagnosis and confirms that your vehicle has the issue, the repair will be performed at no cost to you. • This extended warranty does not apply to any other components or conditions beyond the ones mentioned above, and standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet.

SummaryIn our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA, LLC (“MBUSA”) hereby notifies you of additional benefits regarding your vehicle ownership. What is the concern?

Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz dealership. • Your preferred authorized Mercedes-Benz dealer will perform a diagnosis to determine if the secondary air injection system combination valve is malfunctioning. If diagnosis confirms that your vehicle has the issue, the repair will be performed at no cost to you. • This extended warranty does not apply to any other components or conditions beyond the ones mentioned above, and standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet.
