20 Emission Warranties Required By Law
MBUSA may deny an emission
performance warranty claim if the
failure of a part is the result of:
a. non-compliance with the written
instructions for required maintenance
and use. These written instructions,
including time and mileage intervals
at which maintenance is to be
performed may be found in the
Maintenance Booklet and Operator's
Manual provided with your vehicle.
You are advised to perform all
recommended maintenance or
repairs on your new Mercedes-Benz
vehicle. MBUSA may deny a warranty
claim if your failure to perform the
required maintenance resulted in
the failure of the warranted part
in question. Receipts and service
records covering the performance
of regular maintenance should be
retained in the event questions
arise concerning maintenance. The
receipts and service records should
be transferred to each subsequent
owner of this vehicle.
b. vehicle abuse or maintenance
performed in such a manner that an
emission component was improperly
installed or adjusted substantially
outside the manufacturer's
specifications or which resulted in
removing or rendering inoperative
any component affecting the
vehicle's emissions.
c. using non-EPA certified replacement
parts in the maintenance or repair
of the vehicle which ultimately
proved to be defective in material
or workmanship or not equivalent
from an emission standpoint to the
original equipment part and the
owner is unable to prove otherwise.
