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 Freightliner 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.

I–4Century Class Trucks Maintenance Manual, March 2011
Performing regular maintenance on your Freightliner
will help ensure that your Freightliner delivers safe
reliable service and optimum performance for years
to come. Failure to follow a regular maintenance 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 service or conditions the vehicle will be operating in.
Generally, most vehicles operate under conditions
that fall within one of the four types of service described. Before placing your new vehicle in service,
determine the type of service (Service Schedule I, II,
III, or IV) 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
maintenance schedule table, to determine how often
maintenance 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 operations to be performed at that maintenance interval.
Use the maintenance operation reference numbers to
find detailed instructions in the manual on each operation.
Types of Service
Service Schedule I (severe service) applies to vehicles that annually travel less than 6000 miles (10
000 kilometers) or that operate under severe conditions. Examples of severe service, Schedule I 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 climates; frequent short-distance travel; constructionsite 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 conditions. Examples of Schedule II usage are: operation primarily in cities and densely populated areas;
local transport with infrequent freeway travel; or high
percentage of stop-and-go travel.
Service Schedule III (long-haul transport) is for vehicles that annually travel more than 60,000 miles
(100 000 kilometers) with minimal city or stop-and-go
operation. Examples of Schedule III usage are: regional delivery that is mostly freeway miles; interstate
transport; or any road operation with high annual
mileage.
Service Schedule IV (long haul transport for Optimized Vehicle Configuration) is for vehicles that annually travel over 60,000 miles (100 000 km) and
meet the following qualifications:
• Meritor 15-1/2 inch dampened/ceramic Lite
Pedal LTD clutch with sealed release bearing.
• Synthetic transmission fluid used in transmission.
• Meritor FF–961 or FF–981 front axle (12,000 lb.
capacity) with synthetic lubricant.
• Front suspension with maintenance-free rubber
bushings for 12,000 lb. capacity suspension.
• Meritor RPL series, or Spicer SPL series driveline U-joints.
• Synthetic lubricant used in rear axle.
• Equipped with any Freightliner AirLiner suspen-
sion.
• Equipped with Meritor Q-Plus extended-lube
cam brakes and automatic slack adjusters, front
and rear.
• Standard brake system package including Bendix AD-9 air dryer—mounted on the right-hand
frame rail, located directly behind the front
bumper—with heater, and a Bendix air compressor.
• TRW TAS–65 power steering.
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.

Part 205, Transportation Equipment Noise Emission
Controls, requires the vehicle manufacturer to furnish, with each new vehicle, such written instructions
for the proper maintenance, use, and repair of the
vehicle by the ultimate purchaser to provide reasonable assurance of the elimination or minimization of
noise-emission-control degradation throughout the
life of the vehicle. In compliance with the law, the
noise emission controls maintenance information in
each applicable group of this manual, in conjunction
with the vehicle workshop manual, provides these
instructions to owners.
Recommendations for
Replacement Parts
Replacement parts used for maintenance or repair of
noise emission controls should be genuine Freightliner parts. If other than genuine Freightliner parts
are used for replacement or repair of components
affecting noise emission control, the owner should be
sure that such parts are warranted by their manufacturer to be equivalent to genuine Freightliner parts in
performance and durability.

Among those acts presumed to constitute tampering are the acts listed below:
A. Removal of engine noise-deadening panels.
B. Removal of cab-tunnel or hood noise-
deadening panels.
C. Removal of, or rendering inoperative, the en-
