Determining Scheduled
Maintenance Intervals
Performing regular maintenance on your Freightliner
vehicle will help ensure that your vehicle delivers
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, over-the-road vehicles operate under con-
ditions that fall within one of the two types of service
described. Before placing your new vehicle in ser-
vice, determine the type of service (Service Schedule
I or II) 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
Operation Table for a list of the maintenance opera-
tions to be performed at that maintenance interval.
Use the maintenance operation reference numbers to
find detailed instructions in the manual on each op-
eration.
Types of Service
Service Schedule I (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 I usage are: operation
primarily in cities and densely populated areas; local
transport with infrequent freeway travel; or high per-
centage of stop-and-go travel.
Service Schedule II (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 II usage are: re-
gional delivery that is mostly freeway 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.
