MAINTENANCE PROCEDURE LETTER CODES: I = INSPECT,

R = REPLACE, C = CLEAN

 

IMPORTANT NOTE - Time intervals shown are maximum. Actual use and your experience will determine the frequency of required maintenance.

MAINTENANCE PROCEDURE NOTES:

(1) Low evaporative fuel tanks DO NOT require regular maintenance to maintain emission integrity. * All recommendations to replace are based on the finding of damage or wear during inspection.

IMPORTANT

Time intervals are maximum. Actual use and your experience will determine the frequency of required maintenance.

Record dates of monthly and yearly inspections.

EMISSION DATA

EMISSION CONTROL

(EXHAUST and EVAPORATIVE)

EPA 2010 and Later and/or C.A.R.B. TIER III

The emission control system for the engine is EM (engine modifi cation) and, if the second to last character of the Engine Family on the Emission Control Information label (sample below) is "C", "K", or"T", the emission control system is EM and TWC (3-way catalyst). The fuel tank/fuel line emission control system is EVAP (evaporative emissions). Evaporative emissions for California models may only be applicable to fuel tanks.

An Emission Control Label is located on the engine. (This is an example only, information on label varies by engine family).

PRODUCT EMISSION DURABILITY (EMISSION COMPLIANCE PERIOD)

The 300 hours emission compliance period is the time span selected by the manufacturer certifying the engine emissions output meets applicable emissions regulations, provided that approved maintenance procedures are followed as listed in the Maintenance Section of this manual.
