Severe-Duty Schedule, Motorhome Vehicles

NOTE: Items for emission control service are shown in bold type.

For items marked with a number in parentheses, see footnotes at the end of this schedule.

NOTE: The Severe-Duty Schedule provides maintenance intervals for replacing air cleaner filter if vehicle is driven in severe dust conditions. However, some driving conditions may require even more frequent air cleaner replacement intervals than those shown.

NOTE: Kilometer intervals are rounded off.
