1. Change petroleum-based lubricants at M2 (including M3, M4, and M5). Change synthetic lubricants at M5 only.
2. For Detroit axles, complete this procedure once a year or at the following applicable interval, whichever comes first: every 5000 miles (8000 km) for Schedule I vehicles; every 25,000 miles (40 000 km) for Schedule II vehicles; or every 100,000 miles (161 000 km) for Schedule III vehicles.
3. If equipped with an oil-coalescing desiccant cartridge, replace the cartridge once a year, regardless of mileage. Otherwise use the M5 maintenance interval.
4. Complete this procedure every 25,000 miles (40 200 km), 3 months, or 500 operating hours, whichever comes first.
5. Replace the HVAC air filter at the recommended interval or every six months.
