more we drive, the more we are
exposed to “rare” events, even for
good drivers.1in4ofuswillbe

Reasons given... Consider...
“Belts are uncomfortable” We design our safety belts to enhance
comfort. If you are uncomfortable -
try different positions for the safety
belt upper anchorage and seatback
which should be as upright as
possible; this can improve comfort.
“I was in a hurry”Prime time for an accident.
BeltMinder reminds us to take a few
seconds to buckle up.
“Seat belts don’t work”Safety belts,when used properly,
reduce risk of deathto front seat
occupants by45% in cars,and by
60% in light trucks.
“Traffic is light”Nearly 1 of 2 deaths occur in
single-vehicle crashes,many when
no other vehicles are around.
“Belts wrinkle my clothes” Possibly, but a serious crash can do
much more than wrinkle your clothes,
particularly if you are unbelted.
“The people I’m with don’t
wear belts”Set the example, teen deaths occur 4
times more often in vehicles with
TWO or MORE people. Children and
younger brothers/sisters imitate
behavior they see.
“I have an air bag” Air bags offer greater protection when
used with safety belts. Frontal air
bags are not designed to inflate in
rear and side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea.Peoplewho are
ejected are 40 times more likely
to DIE.Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.

8. Confirmation of enabling BeltMinder is provided by:
•The safety belt warning light flashing four times per second for three
seconds.
•Followed by three seconds with the safety belt warning light off.
•Once again, the safety belt warning light will flash four times per
second for three seconds.
9. After receiving confirmation, the deactivation/activation procedure is
complete.
Safety belt extension assembly
If the safety belt is too short when fully extended, there is an eight inch
(20 cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained from your dealer at no cost.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
Do not use extensions to change the fit of the shoulder belt
across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front seat belt buckle

Positions of the ignition
1. ACCESSORY, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
2. LOCK, locks the steering wheel,
automatic transmission gearshift
lever and allows key removal. For
vehicles equipped with a manual
transmission, you must depress the
ignition release lever to release the
key.
3. OFF, shuts off the engine and all accessories without locking the
steering wheel. This position also allows the automatic transmission shift
lever to be moved from the P (Park) position without the brake pedal
being depressed.
4. ON, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
5. START, cranks the engine. Release the key as soon as the engine
starts.
Starting the engine
Operation of a diesel engine near flammable vapors in the air
may cause the engine speed to increase uncontrollably and over
speed. If this situation occurs, mechanical damage, fire, explosion,
personal injury or death could result.Turning off the ignition key
will not slow or stop the engine due to uncontrollable fueling of the
engine through flammable vapors being drawn into the engine air
inlet.Operation of components such as starter, alternator, electric
motors, etc. and static electricity could also ignite flammable vapors.
Do not operate the truck in the possible presence of flammable vapors
unless both a complete hazard analysis is performed and necessary
additional safety processes and/or equipment such as vapor testing, air
intake shutoff devices, ventilation, etc. are utilized. The operator is
responsible for using those processes and/or equipment to ensure that
the diesel engine and all other components on the truck can be
operated safely under the specific conditions and hazards that may be
encountered.

Note:When starting the engine, do not press the accelerator as engine
damage may result.
1. Ensure headlamps and all accessories are turned off, the parking
brake is applied and the transmission is in the neutral position (or P
[Park] for Allison 2200 transmissions).
2. Turn the key to ON, but do not start the engine. In cooler weather,
the air intake heater may activate the WAIT TO START light in the
instrument cluster.
If the WAIT TO START light
illuminates,do notcrank the engine
until the light goes off.
If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could cause an explosion
and result in property damage and/or personal injury.
3. When the WAIT TO START light turns off, turn the key to START;
when the engine starts, release the key.
If the engine does not start after 30 seconds of cranking, allow two
minutes for the starter to cool before trying again. Excessive cranking
may damage the starter.
After the engine starts:
•On some engines, the WAIT TO
START light should illuminate
after the engine starts. Allow the
engine to idle about three
minutes or until the engine
coolant temperature gauge begins to rise. Maintain idle speed until the
WAIT TO START light cycles off to indicate the air intake heater has
shut off (approximately six minutes). Operating the engine at higher
speeds will reduce the effectiveness of the air inlet heater.

a buildup of heavy deposits of carbon and rust on valve stems causing
them to stick which, in turn, can cause valvetrain damage.
The following cold weather idling guidelines must be followed:
•Avoid idling the engine for more than 10 minutes at a time.
•Use a minimum of 45 Cetane Diesel fuel or use Cetane Index
improvers from a reputable manufacturer.
•Maintain a minimum idle of 1250 RPM by using the hand throttle.
Always make sure that the parking brake is applied and the
transmission is in neutral before applying the hand throttle.
•Maintain the engine cooling system properly.
•Do not shut the engine down after an extensive idling period (10
minutes or more). Drive the vehicle under load for several miles at
normal operating temperatures to burn off any accumulated carbon
and varnish.
•Consider using an engine block heater, approved winter fronts and/or
radiator shutters where conditions warrant.
Winter fronts
The use of winter fronts, or other air-restrictive devices mounted in front
of the radiator on vehicles with chassis-mounted charge air coolers, are
not recommended unless extremely cold weather conditions exist. Air
flow restriction can cause high exhaust temperatures, power loss,
excessive fan usage and a reduction in fuel economy. If you must use a
winter front, the device should have a permanent opening of at least 120
sq in. (774 sq. cm) directly in line with the fan hub.
Hot weather operation
•Keep the engine cooling system filled with a clean, permanent coolant
solution to protect 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 in to the
next lower gear to increase engine RPM.
Starting a turbocharged engine with the vehicle on a steep grade
When starting a diesel engine when the loaded vehicle is on a grade, the
engine RPM will start to fall slightly when the clutch is engaged; do not
