General Maintenance Schedule Information
Performing regular maintenance on your vehicle will help ensure that your vehicle delivers safe reliable service and optimum performance for years to come. Failure to follow a regular maintenance program can result in inefficient operation and unscheduled down time.
When the vehicle reaches the distance given for a maintenance interval, see the Vehicle Maintenance Schedule Table for a list of the maintenance operations to be performed at that maintenance interval. Use the maintenance operation reference numbers to find detailed instructions in the manual for each operation.
Note: Maintenance instructions in this manual are based on average vehicle use and normal operating conditions. Unusual vehicle operating conditions may require service at more frequent intervals.
For specific engine maintenance information, see the Cummins or Mercedes-Benz Operation and Maintenance Manual.
Important: Maintenance operations appearing in italics in the following table are for noise emission control components. Numbers in the table are reference numbers matching those in the text of this manual.
