Foreword
Scheduled maintenance provides a key element for the safe operation of your vehicle. A proper
maintenance program also helps to minimize downtime and to safeguard warranties. This
maintenance manual provides information necessary for years of safe, reliable, and cost-efficient
vehicle operation.
IMPORTANT: The maintenance operations in this manual are not all-inclusive. Also
refer to other component and body manufacturers’ instructions for specific inspection
and maintenance instructions.
Perform the operations in this maintenance manual at scheduled intervals. Perform the pretrip
and post-trip inspections, and daily/weekly/monthly maintenance, as outlined in the vehicle
driver’s manual. Major components, such as engines, transmissions, and rear axles, are covered
in their own maintenance and operation manuals, that are provided with the vehicle. Perform any
maintenance operations listed at the intervals scheduled in those manuals. Your Sterling
Dealership has the qualified technicians and equipment to perform this maintenance for you.
They can also set up a scheduled maintenance program tailored specifically to your needs.
Optionally, they can assist you in learning how to perform these maintenance procedures.

disassembly, assembly, installation, and specifications.

bulletin is usually canceled. The service bulletins manual is available only to
dealers. When doing service work on a vehicle system or part, check for a valid
service bulletin for the latest information on the subject.
