1995 CHEVROLET SUBURBAN air condition

If your engine has more than one emissions classification, the classification
is determined by the Gross Vehicle Weight Rating (GVWR) of your vehicle
as shown on the Certification Label. See “Loading Your Vehicle” in the
Index.
Once you’ve determined your engine type and,
if necessary, emissions
classification, you’ll need
to decide which of the two schedules is right for
your vehicle. See Definitions for Maintenance Schedule I and Maintenance
Schedule I1 following.

Emissions
Follow Maintenance Schedule I if any one of these is true for your vehicle:
