1. Inspect the air filter every 6 months. Replace the air filter every 12 months, or when filter restriction exceeds the value shown in  (if equipped with an air restriction gauge).
2. Replace the organic acid technology (OAT) coolant every 600,000 miles (965 400 km). Supplemental coolant additives (SCAs) are not used with OAT coolant. See the applicable engine operation and maintenance manual for further information. For Cummins engine service literature, refer to the  Cummins Online  website. For Detroit™ engine service literature, refer to the  Detroit Diesel  link on the DTNA TechLit website https://www.dtnatechlit.com/portal-public 
3. For oil and filter change intervals, see the applicable Allison Operator's Manual.
4. For Detroit axles, complete this procedure once a year or at the following applicable interval, whichever comes first: every 5000 miles (8000 km) for Category I vehicles; or every 10,000 miles (16 000 km) for Category II vehicles.
5. For Detroit™ rear axles with petroleum-based oil, change the lubricant every 100,000 miles (161 000 km) or every 12 months, whichever comes first; if synthetic oil is used, change the lubricant every 250,000 miles (402 000 km) or every 36 months, whichever comes first. For Meritor rear axles with petroleum-based oil, change the lubricant at 100,000 miles (161 000 km) or at 12 months of service, whichever comes first, and every 24 months thereafter; if synthetic oil is used, change the lubricant every 250,000 miles (402 000 km) or every 36 months, whichever comes first.
6. IMPORTANT: Lubricate every 6 months or every 18,000 miles (30 000 km), whichever comes first
7. See the Bosch Pin Slide Disc Brakes Service Manual for more information.
8. This operation applies specifically to vehicles used during winter months in areas where corrosive materials are used on the highways.
9. Replace the desiccant and coalescent filter every 18,000 miles (30 000 km) or every 18 months.
10. Complete this procedure every 25,000 miles (40 225 km), 3 months, or 500 operating hours, whichever comes first.
