Summary
In 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 ignition coil on your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 15 years / 150,000 miles (whichever occurs first),and applies to the vehicle regardless of ownership.

Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz dealership. • If your preferred authorized Mercedes-Benz 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.
