Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz dealership. This extended
warranty does not cover any other engine or electrical components 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. In the
case of failure of any other engine or electrical system component other than the aforementioned part beyond the vehicle’s original
New Vehicle Limited Warranty of 4 years/50,000 miles, the associated repair will not be covered and will remain your responsibility.
What if I already paid for a repair?
If your vehicle has exceeded the original warranty’s mileage or time period, and you have already paid to have your outside
temperature sensor replaced or ECU software updated due to the above described condition, you may be eligible to receive
reimbursement under this warranty extension. Reimbursement for your replacement costs can be obtained by presenting adequate
documentation to your authorized Mercedes-Benz dealer. Requests for reimbursement may include expenses for Mercedes-Benz
replacement parts, labor, fees, and taxes. Reimbursement may be limited to the amount the repair would have cost if completed by
an authorized Mercedes-Benz dealer. Contact your Mercedes-Benz dealer for more information on obtaining this reimbursement.
Repairs performed by a non-Mercedes-Benz dealership might not be reimbursed.
Please contact your authorized Mercedes-Benz dealership for assistance or additional information (or visit www.mbusa.com). If your

Please apply the enclosed warranty extension addendum to the inside back cover of your vehicle’s Service and Warranty
