Front of vehicle
Lights:Make sure all lights illuminate and are clean.
Make sure headlights function on both high
and low beam. Make sure reflectors are clean,
unbroken and of proper color (red on rear,
amber elsewhere). Make sure the running
lights are also clean and unbroken.
Steering gear:Look for missing or loose fasteners, power
steering fluid leaks and damage to power
steering hoses.
Steering linkage:Make sure connecting links, arms and rods are
not worn or cracked; joints, sockets and boot
seals are not worn or loose and that there are
no loose or missing cotter keys, nuts or bolts.
Tow hooks:Front and rear tow hooks should be inspected
for damage or loose mounting. This is
particularly important on vehicles where tow
hooks are frequently used.
Front suspension
Springs:Inspect for missing, broken or shifted leaves or
leaves that are in contact, or nearly contacting
a tire, rim, brake drum, frame or body
component.
Spring mounts:Inspect spring hangers, bolts, bushings, axle
mounting bolts and nuts for cracks, breaks,
wear, damage and tightness.
Shock absorbers:Inspect for cracks, leaks and missing or broken
bolts or bushings.
Note:Never apply grease to spring pads.
WARNING:Do not operate the vehicle if any suspension
conditions listed in theFront suspensionchart are evident.
Loss of steering or suspension could result in property damage,
personal injury or death.

Rear brakes
Drum:Make sure there are no cracks, dents or holes
and no loose or missing bolts. Make sure brake
linings are not worn, dangerously thin or
contaminated by lubricant.
Rear wheels
Spacers:Make sure dual wheels are evenly separated
and that tires are not touching one another.
Rims:Check for damaged or bent rims. Rims should
not have welding repairs and no rust trails that
indicate it is loose on the wheel.
Lug nuts:Make sure all lug nuts are present and not
loose (look for rust trails around the lug nuts).
There should be no cracks radiating from the
lug bolt holes or distortion of the bolt holes.
Trailer
If you are pulling a trailer, an inspection of the trailer similar to that of
the tractor should be done. Such an inspection should follow trailer
manufacturer recommendations and should include at a minimum:
general condition, landing gear, doors, sides, lights, reflectors,
suspension, brakes, tires, wheels, cargo placement, stability and
tie-downs.
Transmission
If your vehicle is equipped with an automatic transmission, regularly
check the transmission’s neutral start switch. The engine should only
start in the N (Neutral) or P (Park) positions.
WARNING:If the unit starts in gear and/or the neutral start
switch is not functioning correctly, the vehicle may inadvertently
move which could result in property damage, personal injury or death.
Check the transmission fluid level and shift linkage for proper operation.

WARNING LIGHTS AND CHIMES
Base instrument cluster with standard measure shown; metric
similar
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Note:Some warning lights are
reconfigurable telltale (RTT)
indicator lights and will illuminate in
the message center. These lights
function the same as the other
warning lights.

disengaged.
Turn signal:Illuminates when the
left or right turn signal or the
hazard lights are turned on. If the
indicators stay on or flash faster, check for a burned out bulb.
High beams:Illuminates when the
high-beam headlamps are turned on.
Key-in-ignition warning chime:Sounds when the key is left in the
ignition in the off or accessory position and the driver’s door is opened.

WARNING:Always remember to turn on your headlamps at
dusk or during inclement weather. The Daytime Running Lamp
(DRL) system does not activate your tail lamps and generally may not
provide adequate lighting during these conditions. Failure to activate
your headlamps under these conditions may result in a collision.
PANEL DIMMER CONTROL
Use to adjust the brightness of the
instrument panel and all applicable
lit components in the vehicle during
headlamp and parking lamp
operation.
•Tap the top or bottom of the
control to brighten/dim all interior
lit components incrementally, or
•Press and hold at the first
position the top or bottom of the
control until the desired lighting level is reached.
AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident the alignment of your headlamps
should be checked by a qualified service technician.
TURN SIGNAL CONTROL
•Push down to activate the left
turn signal.
•Push up to activate the right turn
signal.
If your vehicle is a tractor, the turn signals may not shut off when a turn
is completed; this is normal. Please see your dealer if there are any
questions on the options your vehicle has been equipped with.

STARTING
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 automatic
transmission gearshift lever if
equipped with a P (Park) position
and allows key removal.
3. OFF – shuts off the engine and all
accessories.
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
WARNING: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:If equipped with Eaton UltraShift transmission, allow UltraShift to
power up before starting the engine. Engine cranking is delayed until the
transmission power up is complete and the gear display shows a solid N.

WARNING:Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not
have enough braking power and your chances of having a collision
greatly increase.
Trailer lamps
Trailer lamps are required on most towed vehicles. Your vehicle may be
equipped with one of two possible trailer wiring designs. Make sure all
running lights, brake lights, turn signals and hazard lights are working.
See your dealer or trailer rental agency for proper instructions and
equipment for hooking up trailer lamps.
Driving while you tow
When towing a trailer:
•Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 km) of trailer towing and don’t make full-throttle starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Use a lower gear to eliminate excessive shifting and assist in
transmission cooling.
•Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to theScheduled Maintenance Guide
chapter for more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
