Schedule Use

Before placing your new vehicle in service, determine the correct maintenance intervals that apply to your intended use of the vehicle. Refer to the Maintenance Schedule Table to determine the distance interval at which each maintenance operation must be performed to comply with your vehicle's schedule. A detailed description of maintenance operations can be found later in this section‪

When the vehicle reaches the actual distance given for an interval, refer to the Maintenance Interval Tables to find the Maintenance Operation Set that applies to that interval. Then perform the maintenance operations listed in the applicable Maintenance Interval Operation Table. ‪

Complete each Maintenance Operation Set at the required interval. For example, when you have completed Maintenance Operation Set M3 under the 16th maintenance number listed in the Maintenance Interval Table, repeat the pattern. For the 17th maintenance, do Maintenance Operation Set M1, under the first maintenance number listed in the Maintenance Interval Table.‪

Note: For Severe Service, the pattern repeats after 15 maintenance numbers, not 16 (as for Short Haul and Long Haul).
