Severe duty schedule Items for Emission Control Service are shown in italics. The Severe Duty Schedule provides maintenance intervals for replacing your air cleaner filter if you drive in severe dust conditions. However, the conditions you drive in may require even more frequent air cleaner replacement intervals than those shown. Check with your dealer. Extremely dusty conditions will require more frequent replacement of your air filter. Check your air filter at 5,000 km (3,000 miles). If it is dirty, replace it and then keep replacing it at the same interval (every 5,000 km [3,000 miles]). If it is not dirty, check it again at 10,000 km (6,000 miles) and again at 15,000 km (9,000 miles) until you determine your unique maintenance interval. Do not go beyond 50,000 km (30,000 miles) as described in the chart. If in doubt, see your dealer. Non-synthetic rear axle lubricants should be replaced every 5,000 km (3,000 miles) or 3 months, whichever occurs first, during extended trailer tow operation above 21°C (70°F) ambient and wide open throttle for extended periods above 72 km/h (45 mph).

These lubricants are not to be checked or changed unless a leak is suspected, service required or the axle has been submerged in water.
