Diesel Messages
WARNING
When the CLEANING EXHAUST
FILTER message appears in the
information display, do not park near
flammable materials, vapors or structures
until filter cleaning is complete. Action
Message
The coolant additive needs checking.
CHECK COOLANT
ADDITIVE
Your vehicle has entered the cleaning mode. Various engine
actions raise the exhaust temperature in the diesel particulate filter system to burn off the particles (exhaust soot). After
the vehicle burns off the particles, the exhaust temperature returns to normal levels. This message is normal.
CLEANING EXHAUST
FILTER
The diesel particulate filter is full of particles (exhaust soot)
and you are not operating the vehicle in a manner that allows normal cleaning. One of these messages stays on until the
exhaust filter cleaning has begun, at which time the CLEANING EXHAUST FILTER message displays. We recommend you
drive the vehicle above 30 mph (48 km/h) until the CLEANING EXHAUST FILTER message turns off.
EXHAUST OVER-
LOADED DRIVE TO CLEAN
EXHAUST AT LIMIT
DRIVE TO CLEAN NOW
The diesel particulate filter continues to fill with particles
(exhaust soot) if you ignore this message. The service engine soon light illuminates and engine power may be limited, if
cleaning is not permitted. Your vehicle requires dealer service to restore it to full –power operation.
Your vehicle exhaust system temperature exceeds intended operating range. If this warning occurs, a chime sounds,
followed by reduced engine power. The engine shuts down
when your vehicle speed is below 3 mph (5 km/h). Stop the
vehicle as soon as safely possible. Have the system checked by an authorized dealer.
STOP SAFELY NOW
The diluted engine oil needs to be changed.
ENGINE OIL DILUTED
Your vehicle will have reduced engine torque until the engineis warmed sufficiently.
ENGINE WARMING
REDUCED POWER
The powertrain control module intentionally turns the engineoff due to your vehicle being in the final 30 seconds of a
countdown. The diesel engine shutdown for extended idling is an optional feature.

STEERING
To help prevent damage to the power
steering system:
•
Never hold the steering wheel at its
furthest turning points (until it stops)
for more than three to five seconds
when the engine is running.
• Do not operate the vehicle with a low
power steering pump fluid level (below
the MIN mark on the reservoir).
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
(or if the engine is turned off), you can
steer the vehicle manually, but it takes
more effort.
If the power steering system exhibits heavy
or uneven efforts, check for the following
before seeking service from your dealer:
• An improperly inflated tire.
• Overloading of front suspension.
• Uneven vehicle loading.
• Binding suspension components.
If the power steering system wanders or
pulls, check for:
• An improperly inflated tire.
• Uneven vehicle loading.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components. •
Improper vehicle alignment.
• High crosswinds.
If any steering components are serviced or
replaced, install new fasteners (many are
coated with thread adhesive or have
prevailing torque features which may not
be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.

Towing Vehicles Equipped with a
Driver-controlled Differential Lock
Note:
If you have to tow your vehicle to a
service facility with the drive axle wheels on
the ground, it is necessary to remove the
axle shafts before towing your vehicle.
Removing Axle Shafts before Towing
1. Shift the main differential to the unlocked (disengaged) position; the
differential lock light turns off.
2. Remove the cap screws and washers or stud nuts and washers from flanges
of both axle shafts.
3. Loosen the tapered dowels in the flanges of both axle shafts by holding
a 1 ½-inch diameter brass drift or
hammer against the axle shaft center
and hitting it with a five or six pound
hammer.
Note: Do not use a chisel or wedge to
loosen the axle shafts and dowels. Use of
a chisel or wedge can damage the hub, axle
shafts and oil seals.
4. Remove the tapered dowels and both axle shafts from the axle assembly.
5. Assemble a cover over openings of both wheel ends to prevent loss of
lubricant and keep dirt away from the
wheel bearing cavities.
Note: One of the axle shafts has two sets
of splines. One set to engage with the
differential side gear and one set to engage
with the shift collar for the differential lock.
It may be necessary to rotate the shaft
slightly to align the gear spline teeth with
the shift collar teeth in order to remove the
axle shaft.
Installing the Axle Shafts
1. Remove the covers from the wheel ends.
2. Shift the differential lock to the unlocked (disengaged) position. 3. Install the axle shafts as outlined in
Steps 4 through 10.
4. Place the gaskets on the wheel hub studs.
5. Push the right-hand axle shaft and gasket into the wheel end and housing
until the shaft stops against the
differential shift collar.
6. Push down and in on the axle shaft flange and rotate the shaft until the
splines of the shaft and shift collar are
engaged.
7. Push the axle shaft further into the housing until the shaft stops against
the differential side gear.
8. Push down on the axle shaft flange and
rotate the shaft until the splines of the
shaft and side gear engage.
9. Push the axle shaft completely into the
housing until the axle shaft flange and
the gasket are flush against the wheel
hub.
10. Install the left-hand axle shaft and gasket into the wheel end.
11. If tapered dowels are required, install
them at each stud and into the flange
of the axle shaft. Use a punch or drift
and hammer, if needed.
12. Install the fasteners and tighten to correct torque value. See the
Workshop Manual.
FIFTH WHEEL OPERATION WARNINGS
Failure to follow the fifth wheel
manufacturer
’s instructions for
hooking and unhooking as well as
sliding the fifth wheel could result in an
accident, personal injury or death.
144
F650750 (TBC), enUSA, First Printing Towing
Follow the tire manufacturer's
recommended cold inflation pressure for
the tire size, load range (ply rating) and
steer axle loading typical for their operation
(each steer axle tire equals ½ steer axle
loading).
Special applications may warrant a setting
based on experience with the type of tire
operating loads and conditions. Radial tires
are more sensitive to toe-in setting than
bias ply tires. Fine tuning school bus
alignment to line-haul truck standards
does not drastically improve tire tread life.
STEERING SYSTEM
INSPECTION
WARNING
Failure to maintain the steering
system in proper condition can cause
reduced steering ability resulting in
property damage, personal injury or death. Note:
Have any steering problems
immediately corrected by a qualified service
technician.
Ask your service technician to examine the
steering mechanism. Only minor
adjustments may be necessary.
Regular inspections should include:
• Checking the tie rod, drag link end
clamp bolts and ball joints for proper
tightness.
• Checking for installation and spread of
cotter pins and tightness of nuts at
both ends of the tie rod and drag link.
• Checking that the pitman arm (steering
arm at steering gear) mounting is tight
and locked. Check system for leaks or
hose chafing. Repair immediately, if
necessary. •
Maintaining proper steering gear and
power steering pump lubricant levels.
• Checking steering column joint bolts
and steering linkage, particularly for
body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check
steering column joint bolt tightness every
60,000 mi (96,000 km) or annually,
whichever occurs first. Do not overtighten
the bolts.
Hydraulic System
Whenever draining and refilling the power
steering's hydraulic system for any reason,
bleed air from the system before returning
the vehicle to service. Failure to bleed the
hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware
of the proper procedures for filling and
bleeding the system.
SUSPENSION SYSTEM
INSPECTION
Note: Do not adjust air suspension height
to any setting other than the specified
setting. Altering the height setting changes
the driveline angle and may result in
unwarrantable component damage, such
as transmission component damage.
Verify drive axle air suspension height and
height control valve performance at engine
oil change intervals.
Periodically check:
• Condition of spring leaves for evidence
of fatigue, bending or breakage.
• Condition of suspension mounting
brackets and bushings.
• Torque rod mounting fasteners for
tightness.
222
F650750 (TBC), enUSA, First Printing Maintenance
•
For proper suspension alignment.
Maintain proper alignment at all times.
• U-bolts. After the chassis has been
operating under load for 1,000 mi
(1,600 km) or six months (whichever
comes first), the U-bolt nuts must be
re-torqued. Re-torque the U-bolt nuts
every
37,000 mi (60,000 km)
thereafter. Clean and lubricate the
U-bolt and nut threads and seats to
make sure a like new condition when
re-torqueing. See
Spring U-Bolt
Check (page 223).
FRAME AND TOW HOOK
INSPECTION
Your vehicle's chassis is manufactured
with frame rails of either HSLA steel or
heat-treated steel. Handle each in a
specific manner to make sure maximum
service life. Consult the service manual or
an authorized dealer before attempting
frame repair or modification.
It is important, particularly on vehicles that
use tow hooks frequently, to inspect the
front and rear tow hooks for damage or a
loose mounting.
REAR AXLE FLUID CHECK
Your rear axle may have an optional
synthetic lubricant that allows the use of
extended service intervals. A tag on the
filler plug identifies the use of the synthetic
lubricant.
Only use a lubricant that meets
manufacturer specifications. Only use a
lubricant that meets manufacturer
specifications. Use of a non-approved rear
axle lubricant may cause internal axle
component damage. See Capacities and
Specifications
(page 256). Checking the Fluid Level
1. Park your vehicle on level ground.
2. Set the parking brake and shift into
position neutral (N) or park (P). Turn
the engine off.
3. Clean any dirt from around the axle filler plug.
4. Remove the filler plug and inspect the lubricant level. It should be at the
bottom of the filler plug opening.
5. Add lubricant, if necessary, through the
filler plug opening.
6. Clean and install the filler plug securely.
Changing the Fluid
Note: Drain the rear axle while the lubricant
is warm.
1. Park your vehicle on level ground.
2. Set the parking brake and shift into position neutral (N) or park (P). Turn
the engine off.
3. Clean any dirt from around the axle filler and drain plugs.
4. Remove the filler and drain plugs. Drain
the lubricant into a suitable container.
Dispose of all used automotive fluids
in a responsible manner following your
local authorized standards.
5. Clean and install the drain plug securely.
6. Add lubricant through the filler plug opening.
7. Clean and install the filler plug securely.
SPRING U-BOLT CHECK
Check U-bolt nuts and re-torque every
37,000 mi (60,000 km)
after initial
1,000 mi (1,600 km) re-torque. Clean and
lubricate the U-bolt and nut threads and
seats to make sure they are in peak
condition when re-torqued.

U-bolt Checks and Re-torqueing
Procedures
1. Inspect the threads of the U-bolt and nut for rust and debris. Clean the
threads if contaminated.
2. Using a torque wrench, determine if you can turn any nuts with a force
below the specified torque.
3. Using the lowest discovered torqued nut as a starting point, re-tighten the
nuts using the sequence under U-bolt
and U-bolt nut installation.
U-bolt and U-bolt Nut Installation
1. Inspect the threads of the U-bolt and nut for rust and debris. Clean the
threads if contaminated.
2. Install the U-bolts and nuts and torque
the nuts to seat the cap flat which is
about 74 lb.ft (100 Nm) using a
diagonal pattern. Use the same
diagonal pattern for each of the
following U-bolt nut re-torque steps.

2. Loosen each wheel lug nut ½ turn
counterclockwise, but do not remove
them until the wheel is raised off the
ground.
3. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward on all front and inboard rear
wheels. If you are replacing the
outboard wheel, the valve stem must
be facing inward. Reinstall the lug nuts
until the wheel is snug against the hub.
Do not fully tighten the lug nuts until
the wheel has been lowered.
4. Lower the wheel and fully tighten the lug nuts in the order shown below. See
Technical Specifications (page 249).
