DEALER AUTHORIZATION Date: Mileage: (1) Extremely dusty conditions will require more frequent replacement of your air filter. Check your airfilter at 3,000 miles (5,000 km). If it is dirty replace it and then keep replacing it at the same interval [every3,000 miles (5,000 km)]. If it's not dirty, check it again at 6,000 miles (10,000 km) and again at 9,000 miles(15,000 km) until you determine your unique maintenance interval. Do not go beyond 30,000 miles (50,000km) as described in the chart. If in doubt, see your dealer. 39
