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.

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.

Determining Scheduled
Maintenance Intervals
Performing regular maintenance on your Sterling ve-
hicle will help ensure that your Sterling vehicle deliv-
ers safe reliable service and optimum performance
for years to come. Failure to follow a regular mainte-
nance program can result in inefficient operation and
unscheduled down time.
To determine the correct maintenance intervals for
your vehicle you must first determine the type of ser-
vice or conditions the vehicle will be operating in.
Generally, most vehicles operate under conditions
that fall within one of the three types of service de-
scribed. Before placing your new vehicle in service,
determine the type of service (Service Schedule I, II,
or III) that applies to the intended use of the vehicle.
After determining the vehicle’s type of service, refer
to the service schedule table or the vehicle mainte-
nance schedule table, to determine how often main-
tenance should be performed.
When the vehicle reaches the distance given for a
maintenance interval, see the "Maintenance Interval
Operations Table" for a list of the maintenance op-
erations to be performed at that maintenance inter-
val. Use the maintenance operation reference num-
bers to find detailed instructions in the manual on
each operation.
Types of Service
Service Schedule I (severe service) applies to ve-
hicles that annually travel less than 6000 miles (10
000 kilometers)
or that operate under severe condi-
tions. Examples of Schedule I (severe service) usage
include: operation on extremely poor roads or where
there is heavy dust accumulation; constant exposure
to extreme hot, cold, salt-air, or other extreme cli-
mates; frequent short-distance travel; construction-
site operation; city operation (fire truck); or farm
operation.
Service Schedule II (short-haul transport) applies to
vehicles that annually travel less than 60,000 miles
(100 000 kilometers) and operate under normal con-
ditions. Examples of Schedule II (short-haul trans-
port) usage are: operation primarily in cities and
densely populated areas; local transport with infre-
quent freeway travel; or high percentage of stop-
and-go travel.
Service Schedule III (long-haul transport) is for ve-
hicles that annually travel
more than 60,000 miles
(100 000 kilometers) with minimal city or stop-and-go
operation. Examples of Schedule III (long-haul trans-
port) usage are: regional delivery that is mostly free-
way miles; interstate transport; or any road operation
with high annual mileage.
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 Schedule I (severe service) vehicles equipped with an hourmeter, use maintenance intervals based on hours of operation rather than distance traveled.
†Use Schedule I (severe service) maintenance intervals for vehicles that operate under severe conditions, such as extremely poor roads, heavy dust accumu-
lation, extreme climate, frequent short distance travel, construction-site operation, city operation (garbage truck), or farm operation.
