Clean Idle
To comply with CARB emissions
requirements your vehicle will either have
the Certified Clean Idle label or an Engine
Shutdown System (ESS). Some vehicles,
however, are exempt from these
requirements because of their
configurations (for example: fire truck
service).
Your vehicle may have either of these
labels affixed to the vehicle to identify that
its engine meets the strict low exhaust
emission regulations instituted by the state
of California (and other states that have
chosen to adopt CARB emissions
requirements). Trucks with this type of
engine will not require an Engine
Shutdown System and will be allowed to
idle continuously. It is important that you do
not remove or deface this label. Do not
block it from view. Please contact your
authorized dealership if you need to
replace this label. The dealership will be
able to help you to determine whether or
not your vehicle's engine may be a
candidate for a Certified Clean Idle label if
it did not already have the label.
If you have a PACCAR PX-6 or PX-8
engine, your label will look like the image
below.
