Determining Scheduled
Maintenance Intervals
Performing regular maintenance will help ensure that
your vehicle delivers safe, reliable service and opti-
mum performance. A proper maintenance program
will also help to minimize downtime and safeguard
warranties.
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.
Most vehicles operate in conditions that fall within
one of the three schedules. Before placing your ve-
hicle in service, determine whether Schedule I, II, or
III applies to your vehicle.
Schedules I-III
Schedule I
(severe service) applies to vehicles that
travel up to 6000 miles (10 000 kilometers) annually
or that operate under severe conditions. Examples of
Schedule I usage are:
•
operation on extremely poor roads or where
there is heavy dust accumulation
•
constant exposure to extreme hot, cold, salt air,
or other extreme climates
•
frequent short-distance travel
•
construction-site operation
•
city operation such as fire truck and garbage
truck.
•
farm operation
Schedule II
(short-haul transport) applies to vehicles
that travel up to 60,000 miles (100 000 kilometers)
annually and operate under normal conditions. Ex-
amples of Schedule II usage are:
•
operation primarily in cities and densely popu-
lated areas
•
local transport with infrequent freeway travel
•
high percentage of stop-and-go travel
Schedule III
(long-haul transport) is for vehicles that
travel more than 60,000 miles (100 000 kilometers)
annually with minimal city or stop-and-go operation.
Examples of Schedule III usage are:
•
regional delivery that is mostly freeway miles
•
interstate transport
•
any road operation with high annual mileage
Maintenance Schedules
After determining the schedule appropriate to your
vehicle, refer to the Maintenance Schedules to deter-
mine when to perform the Initial Maintenance (IM)
and the frequency of performing subsequent mainte-
nance intervals for each schedule.
Maintenance Intervals
Refer to Maintenance Intervals for Schedule I,
Schedule II, and Schedule III to determine which
maintenance interval(s) should be performed when
your vehicle reaches the mileage or hours of opera-
tion listed in these tables.
Maintenance Operations
Groups 01 through 83 in this manual have an index
at the beginning of each Group. The index lists the
Title of Maintenance Operations and the mainte-
nance Operation (MOP) Numbers for that Group.
Follow the instructions under the MOP number to
perform the required maintenance.
In addition to the maintenance operations required
for the maintenance interval, perform all the daily
maintenance procedures in
Chapter 11

spection and Daily Maintenance," in the
