WARRANTY COVERAGE EXTENSION

To enhance the satisfaction of our customers, avoid further costs of litigation and return focus to its core
business, Mercedes-BenzeBay logo USA, LLC (MBUSA) entered into a settlement regarding claims relating to the original
equipment seat heaters in model year 2000-2007 M-Class, 2006-2007 R-Class, and 2007 GL-Class vehicles. As
part of the settlement, MBUSA offers extended warranty coverage for repairs necessitated by wear and tear of
seat heater electrodes in the outer bolster of the front driver’s side seat, which in rare circumstances could sear
a hole in the seat cover. The warranty extension lasts for a period of up to May 16, 2020 or 180,000 miles,
whichever occurs first. Warranty coverage is provided on a sliding-scale based on mileage, as described below.

Which Vehicles:

e Model year 2000-2007 M-Class, 2006-2007 R-Class, and 2007 GL-Class vehicles with original
equipment seat heaters but only if the VIN for the vehicle is eligible for the extended warranty as
indicated in NetStar/VMI (“Eligible Vehicles”). Please check the VIN before performing any repair
under the extended warranty.

What Is Covered: The warranty extension covers repairs or replacements necessitated by resistance heating of
the seat heater electrodes, which may result in a sear hole in the outer bolster of the driver’s side seat bottom
cover or seat back cover — that is, when a hot spot occurs in the seat heater a hole may develop in the seat
cover (“Qualified Repair”).

What Is Not Covered: This warranty extension does not apply to other types of issues that may concern the
seat heater (e.g., inoperable, uneven heating, too warm/not warm enough, etc.). These other types of seat
heater issues that may present should be treated in the ordinary course of business without regard to this
extended warranty.

What are the Terms of the Extended Warranty: Warranty coverage for a Qualified Repair in Eligible Vehicles
will be extended on the following sliding-scale of coverage from the original 4 years / 50,000 miles to May 16,
2020 / 180,000 miles (whichever occurs first commencing from the In Service Date).

e For seat heaters in Eligible Vehicles needing Qualified Repairs before May 16, 2020 and having 40,000
miles or less from the Eligible Vehicle’s original in-service date, MBUSA will cover 75% of the reasonable
repair amount. Note: there is no double recovery under the settlement—so if the vehicle owner has other
coverage for this repair (e.g., third party warranty coverage), MBUSA will provide warranty coverage only
up to an amount ensuring that a total of 75% of the repair is covered. Generally speaking, this means that
the other 25% of your charges must be collected from the customer.
