A published detailed article is not available for this reference yet.
Confirm the exact configuration
Make, model and year alone do not establish applicability. Confirm the VIN, engine, transmission, axle or brake option, market and build date in the manufacturer’s service information.
Choose the applicable service schedule
Use the normal or severe-duty schedule that matches actual operation. Commercial use, idling, towing and dusty conditions can change requirements. Record mileage, engine hours where applicable, dates and completed work; do not substitute generic intervals for the manufacturer’s schedule.
