(1) Extremely dusty conditions will require more frequent
replacement of your air filter. Check your air filter at
3,000 miles (5,000 km). If it is dirty replace it and then
keep replacing it at the same interval (every 3,000 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 (50,000 km) as described
in the chart. If in doubt, see your dealer.

(3) City delivery vehicles and other unique applications that
require constant turning may need more frequent tire
rotation. You may need to develop your own tire
rotation interval based on your own observations of tire
wear. If in doubt, see your dealer.
