VEHICLE INSPECTION INFORMATION
To be sure your vehicle is ready to operate, conduct a pre-trip inspection
at the beginning of each work period. Follow the steps listed in this
section to ensure a proper vehicle inspection procedure. The pages in
this section may be produced locally and used on a regular basis.
WARNING:Exercise great caution when working on a vehicle
equipped with an automatic fan clutch. The fan starts in motion
only after the engine coolant reaches a predetermined temperature or
the refrigerant pressure (if equipped with air conditioning) reaches a
predetermined setting. The fan starts at this point with no advance
warning. Never reach near, or permit objects to protrude into, the fan
blade radius while the engine is running as this could result in vehicle
damage, personal injury or death.
WARNING:Do not operate the vehicle if any suspension
conditions listed in the following charts are evident. Loss of
steering or suspension could result in property damage, personal injury
or death.
WARNING:If a wheel must be changed, obtain expert tire
service help. Mounting and un-mounting of tires should only be
performed by a qualified technician using necessary safety procedures
and equipment, otherwise the result could be property damage,
personal injury or death.
Note:Always make sure the parking brake is applied before starting the
engine.

WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It takes you longer to stop the vehicle. Have
the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Charging System
It illuminates when the 12–volt battery is not charging properly.
Contact your authorized dealer as soon as possible. This
indicates a problem with the electrical system or a related
component.
Check Fuel Cap (gasoline engine only)
It illuminates when the fuel cap may not be properly installed.
Continued driving with this light on may cause the service
engine soon warning indicator to come on.
Check Suspension
It illuminates when the air suspension dump switch has been
activated.
Check Transmission (Allison automatic transmission only)
It illuminates while driving if a problem has been detected in
the transmission; shifting may be restricted. Depending on the
severity of the problem, the shifter’s digital read-out may turn
blank.
On MD 3000 series transmissions,operation may continue in order to
reach service assistance. The control unit may not respond to shift
selector requests, since operating limitations are being placed on the
transmission (i.e. upshifts and downshifts may be restricted). Direction
changes do not occur.
Cruise Control
It illuminates when you switch this feature on.

Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
•Above normal coolant temperatures could be experienced while
driving in a transmission gear ratio which lugs the engine. To correct
this problem, engine speed should be increased by downshifting into
the next lower gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate the vehicle with the power steering pump fluid level
below the ADD mark on the MAX. COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by your authorized dealer.
•Heavy or uneven steering efforts may be caused by low power
steering pump fluid level. Check for low power steering pump fluid
level before seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX. HOT side of the power steering reservoir dipstick, 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 steering wanders or pulls, check for:
•underinflated tire(s) on any wheel(s)
•uneven vehicle loading
•high crown in center of road
•high crosswinds
•wheels out of alignment
•loose or worn suspension components.

AIR SUSPENSION (IF EQUIPPED)
Note:
The vehicle must not be operated without air in the suspension
springs. Operating the vehicle without air in the suspension springs damages
the suspension, degrades ride performance and may cause property damage.
The air suspension system automatically adjusts to different loads to
maintain a constant frame height, allows for ease of vehicle loading and
provides improved vehicle ride and increased driver comfort.
Air Suspension Dump Switch
Note:The suspension dumps air when the ignition is in the accessory or
on position, but fills only when the ignition is in the on position.
The system is controlled by a switch
located in the overhead switch
pack. It operates only when the
ignition is in the accessory or on
position and the air tanks have
sufficient pressure to fill the air
springs. When the ignition is turned
off, the suspension remains in
whatever state it was last set.
Pressing the lower portion of the switch exhausts air from the air
springs, lowering the frame for loading. Pressing the upper portion of the
switch fills the air springs so the vehicle remains at normal ride height.
System Indicator Light
The air suspension indicator light illuminates when the switch
has been activated to release air pressure in the rear air shocks.
Never drive the vehicle when the warning lamp is illuminated
and there is low (or no) air pressure in the shocks.
Connecting and Disconnecting a Trailer with Air Suspension and
Air Suspension Dump Switch
When connecting to a trailer:
•Press the lower portion of the switch to exhaust air from the air
suspension system.
•Press the upper portion of the switch, then raise the landing gear
after making the connection to the trailer.
When disconnecting the trailer:
•Lower the landing gear, then press the lower portion of the switch.
•Disconnect the brake hoses, trailer-side and rear light connectors,
then pull the release lever on the fifth-wheel.

The upper portion of the switch must be pressed before operating with a
trailer or operating in the bobtail mode.
Suspension Conversions
WARNING:When operating a loaded vehicle, the driver must
keep all adjustable axles on the ground at all times, supporting
their share of the vehicle’s load. Failure to do so can overload other
axles, tires, wheels, springs, steering components, brakes and frames,
resulting in early component failure, loss of vehicle control, possible
property damage and personal injury.
It is not recommended, or approved, that suspension conversions be
performed. However, it is understood that, on occasion, aftermarket
add-on suspensions are installed by others on the truck chassis which
allow operator control for weight transfer from other axles (i.e., air lift
axles).
UPFITTER CONTROLS (IF EQUIPPED)
The upfitter option package
provides four switches, mounted in
the center of the instrument panel.
These switches are always on
whether the engine is running or
not. Make sure you put the switches
in the off position to avoid draining
the battery when the vehicle is not
being used. It is recommended that the engine remain running to
maintain battery charge when using the upfitter switches for extended
duration or higher current draws. (This is even more important for
vehicles with a diesel engine since the glow plugs are also draining
battery power when the ignition key is in the on position.)
Each switch provides 10 amps of electrical battery power for a variety of
personal or commercial uses.
There is also a relay box located on the passenger side end of the
instrument panel. See your authorized dealer for service.
Switch access location is in a connector located in the engine
compartment. More detailed information can be found at

Chassis-mounted Charge Air Cooler
Visually inspect the core assembly for debris and clogging of external fins
with the engine off. Prior to engine operation, remove any debris
blocking the core.
•Turbocharger-to-charge air cooler
•Charge air cooler-to-intake manifold pipe
•Mounting bracket
•Chassis-mounted charge air cooler core
Inspect air intake piping:
•Check for accumulation of salt deposits (where applicable).
If present, disassemble and clean the complete air intake piping
system. If the intake piping is pitted, use Motorcraft® Silicone Gasket
and Sealant TA-30 to seal joints against leakage.
•Check for loose hoses and clamps.
•Check for ruptured or collapsed hoses.
•Check air cleaner housing for cracks.
Suspension 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.
•For proper suspension alignment. This must be maintained at all
times.
•U-bolts. After the chassis has been operating under load for
1000 miles (1600 kilometers) or six months (whichever comes first),
the U-bolt nuts must be re-torqued. The U-bolt nuts must be
re-torqued every 36000 miles (60000 kilometers) thereafter. The
U-bolt and nut threads and seats should be cleaned and lubricated to
make sure a like new condition when re-torquing.
Note:SeeSpring U-bolt checklater in this chapter.
