RE: HVAC Service Warranty Coverage: Various

Models and Model Years (see enclosed list) pate: October 29, 2020

HVAC SERVICE WARRANTY COVERAGE

(Not Effective until December 7, 2020 at the Earliest [see below])

This NCU replaces the prior NCUs issued on May 18, June 25, 2020 and October 1, 2020 and contains
important workshop instructions on how the HVAC Service Warranty repair must be carried out. To enhance the
satisfaction of our customers, avoid further costs of litigation, and return focus to its core businesses,
Mercedes-Benz USA, LLC (MBUSA) has entered into a settlement regarding claims relating to alleged mold and
mildew odors originating from the HVAC system in certain Mercedes-Benz vehicles. As part of the settlement,
MBUSA has agreed to offer sliding-scale warranty coverage for certain vehicles diagnosed as having mold or
mildew odors originating from the HVAC system. Although the settlement has received court approval, warranty
coverage will not take effect until December 7, 2020, when the appeal period for class members will have
expired. If the settlement takes effect, warranty coverage will include cleaning of the evaporator and
replacement of the HVAC filters.

Which Vehicles: The warranty coverage provided by the settlement applies to the following vehicle types and
model years only (“Subject Vehicles”):

204 and 205 C-Class (model years 2008-2019)

X204 GLK-Class (model years 2010-2015)

218 CLS-Class (model years 2012-2017)

207, 238, 212 and 213 E-Class (model years 2010-2019)
156 GLA-Class (model years 2015-2019)

X166 GL-Class (model years 2013-2016)

166 and 292 GLE-Class (model years 2016-2019)

X166 GLS-Class (model years 2017-2019)

166 M-Class (model years 2012-2015)

e 253 GLC-Class (model years 2016-2019)

What Is Covered: The warranty coverage provided by the settlement covers only cleaning the evaporator and

replacing the HVAC filters in Subject Vehicles to address confirmed mold or mildew odors originating in the
Subject Vehicle’s HVAC system (“Qualified Repair”).

What Is Not Covered: The warranty coverage provided by the settlement does not apply to other types of
issues concerning the HVAC system (e.g., inoperable AC system, not hot/cold enough, etc.). Nor does it apply
to odors from the HVAC system not attributable to mold or mildew (e.g., burning or fuel smells, lack of proper
cleaning or maintenance, etc.). These other types of HVAC issues that may present should be treated in the
ordinary course of business without regard to this warranty. Covered repairs are strictly limited to cleaning the
evaporator and replacing the HVAC filters. Thus, by way of example, replacement of the evaporator or HVAC

unit is not covered under the warranty and is not a prescribed remedy for concerns of mold or mildew odors
originating in the HVAC system.

e Goodwill Coverage No Longer Allowed - In light of the significant benefits provided under the
settlement agreement, the Subject Vehicles are no longer eligible for goodwill coverage for repairs
relating to mold or mildew odors emanating for the HVAC system. Coverage for such repairs is strictly
limited to that provided by the extended warranty described in this NCU

When Does Coverage Begin?: The settlement received final approval from the court on September 14, 2020,
but coverage under the extended warranty will not take effect until all rights to appeal have been exhausted.
Assuming there are no appeals, the parties have agreed that class members may begin presenting for
extended warranty coverage on December 7, 2020. Until such time, customers should be advised to visit
the settlement website (www.mercedeshvacsettlement.com) to stay apprised of developments.

What are the Conditions for Coverage: To qualify for coverage of a Qualified Repair, each of the following
requirements must be satisfied with respect to the Subject Vehicle:

e The customer requesting coverage must provide proof that the Subject Vehicle’s currently installed
HVAC filter is a Mercedes-Benz brand or Other Approved Filter.

e Other Approved Filters: Only filters from Behr, Denso, Freudenberg, Mann-Hummel, Valeo will be
accepted as Other Approved Filters. The supplier name must be verified by checking if the supplier
name appears on the side of the filter as shown in the below diagram. No other filter from any other
suppliers will be accepted as an approved alternative filter.

e Other proof that a filter is a Mercedes-Benz brand or Other Approved Filter includes, but is not limited
to, an authorized Mercedes-Benz Service Center (“Service Center”) employee examining the filter and
determining it is a Mercedes-Benz brand or Other Approved Filter, a Service Center invoice indicating
installation of a Mercedes-Benz brand or Other Approved Filter into the Subject Vehicle, or a receipt of
purchase of a Mercedes-Benz brand or Other Approved filter that was self-installed.

e The customer requesting warranty coverage must provide proof that the Subject Vehicle received timely
and proper service in compliance with the Subject Vehicle’s maintenance schedule for the two service
intervals immediately prior to the requested repair. For purposes of this warranty coverage only, such
service is timely if it occurred within three months of the time periods specified in the Subject Vehicle’s

or Independent Service Provider indicating the Subject Vehicle’s maintenance history; information found
in the Service Center’s own service records for the Subject Vehicle; or receipts of parts and materials
used for maintenance performed by the customer.

e A service technician at the Service Center where coverage is requested must verify that the source of
the odor in the Subject Vehicle is mold or mildew odors originating from the HVAC system by inspecting
the Subject Vehicle and excluding all of the following other potential sources for odor:

o Moisture in the vehicle due to: body leaks, condensation hoses, check air intake, sliding roof
drains/leaks, water drains

o Cigarette smell/ashtrays, air fresheners, damping mats/fabrics (e.g. firewall, transmission tunnel),

What are the Terms of the Warranty and Extended Warranty: Coverage for Qualified Repairs will vary
depending on the time period during which the Qualified Repair occurs, as follows:

e Period One is defined as the time period during which the Subject Vehicle has fewer than 4 years or
50,000 miles from the Subject Vehicle’s original in-service date, whichever occurs first, or otherwise has
full coverage for a Qualified Repair under another warranty. Qualified Repairs that occur during Period
One shall be covered for 100% of the cost of the Qualified Repair.

e Period Two is defined as the time period from the end of Period One until the Subject Vehicle has fewer
than 8 years or 100,000 miles from the Subject Vehicle’s original in-service date, whichever occurs first.
Qualified Repairs that occur during Period Two and exceed any warranty/extended warranty coverage
shall be covered for 70% of the cost of the Qualified Repair.

e Period Three is defined as the time period from the end of Period Two until the Subject Vehicle has
fewer than 10 years or 125,000 miles from the Subject Vehicle’s original in-service date, whichever
occurs first. Qualified Repairs that occur during Period Three shall be covered for 50% of the cost of the
Qualified Repair.

e There will be no coverage for Qualified Repairs that occur after the end of Period Three (i.e. more than
10 years or 125,000 miles from the Subject Vehicle’s original in-service date, whichever occurs first).

This warranty and warranty extension applies to covered vehicles regardless of ownership, as long as the Terms
and Conditions of coverage above are satisfied.

The warranty does not cover any components or labor other than cleaning the evaporator and replacing the
HVAC filter (e.g., replacement of the evaporator or HVAC box is not covered). Standard warranty terms and
exclusions apply to all other components.

VMI will display information regarding this warranty in the “Service Packages” section for all affected vehicles
and is detailed below.

The following Damage Code can be claimed for Qualified Repairs performed after the warranty coverage takes
effect: Damage Code 21688 00.

While we regret any inconvenience this may cause, MBUSA is determined to maintain a high level of vehicle
quality and customer satisfaction.
