INFORMATION
Isuzu diesel engines available in the above affected vehicles meet the California Air
Resource Board’s (CARB) optional idling emissions standard of 30 grams per hour of
oxides of nitrogen (NOx) with no increase in the emission of other regulated pollutants.
As a result these vehicles have been approved as “Certified Clean Idle” and are
“exempt” from the Engine Shutdown System (ESS) requirement pursuant to Section
1956.8 of Title 13, California Code of Regulations. As required by the ESS regulation,
for “Certified Clean Idle” vehicles, Isuzu has introduced a tamper resistance “Certified
Clean Idle” label located on the driver’s side door panel.
It is important that this label remain, permanently, on the vehicle to identify it as
“Certified Clean Idle”. CARB requires this label as evidence that, at the time of
manufacture, the engine installed met the applicable emission standards. Should the
label be found missing or damaged during an inspection, a citation and penalties may
be issued. If the vehicle is operated in California with a damaged or missing clean idle
label, Isuzu recommends vehicle operators follow the 5 minute ESS requirement by
manually turning off the engine. Following this ESS requirement will keep the vehicle
operation compliant until a replacement label can be installed.
“Clean Air Idle” labels are printed with a serial number and registered to an individual
VIN. As a result, a replacement label will also include a new serial number which must
be registered to the vehicle’s VIN by the manufacturer. The below information is
provided to assist in acquiring, replacing and registering a replacement label.

Commercial Truck of America (ICTA) vehicle distribution. Contact vehicle distribution at
