EPA NOISE EMISSION CONTROL INFORMA-
TION LABEL

The EPA noise emission control information label is located on
the passenger side B-pillar (door latch post). The label is re-
quired by the EPA and includes a tamper-proof feature. If the
label is tampered with, a void pattern will appear across the la-
bel. Notify the dealer or the manufacturer if the label is missing
or displays a void pattern (Figure 1-6).

The label contains the name of the manufacturer, the month
and year the vehicle was manufactured, a statement regarding
vehicle conformance to applicable U.S. EPA regulations, and a
description of acts prohibited by the Noise Control Act of
1972.
