Air Filtration System – If Equipped
An air filter is included in the optional Security Group.
Filter media includes a particle filtration layer and a
charcoal layer. The filter will reduce, but not eliminate,
diesel and agricultural smells. The filter acts only on air
coming from outside the vehicle; it does not filter air
inside the passenger compartment.. The air filter change
interval coincides with engine oil and filter change
intervals. As with oil changes, the interval is shorter for
heavy duty service or dusty conditions. Refer to "Main-
tenance Schedule" in Section 7. See your authorized
dealer for service.
