STARTING A DIESEL 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 does 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.
WARNING: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.
Switch the ignition on and wait until the glow plug indicator
goes off.
Note:You can only operate the starter for a maximum of 30 seconds at
a time. Allow two minutes before cranking the starter again.
Note:On some engines, the glow plug indicator illuminates 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 glow plug indicator goes off. Operating the engine at higher
speeds reduces the effectiveness of the air inlet heater.
Note:When starting a cold engine, increase the engine RPM slowly to
make sure adequate lubrication is available to the bearings.

Filling the DEF Tank
WARNING:Make sure that DEF does not come into contact
with eyes, skin or clothing. Should DEF contact your eyes, flush
them with plenty of water and contact a physician. Clean affected skin
with soap and water. If DEF is swallowed, drink plenty of water and
contact a physician immediately.
WARNING:Refill DEF in a well-ventilated area. When opening
the cap on the DEF tank or bottle containing DEF, ammonia
vapors may escape. The vapors can be irritating to skin, eyes and
mucous membranes. Inhaling ammonia vapors can cause burning to the
eyes, throat and nose and cause coughing and watery eyes.

If the fuse is not blown and the brake lamps are working properly, the
following procedure allows you to move the gearshift lever from position
P:
1. Apply the parking brake, and
turn the engine off.
2. Remove the lower finish panel
below the steering column.
3. Turn the key to the on position,
but do not start the engine.
4. Pull back on the solenoid, and
at the same time, shift the
transmission into positionN.
5. Start your vehicle.
See an authorized dealer as soon as
possible if this procedure is used.
Six–speed TorqShift® Transmission
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in position P. Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
WARNING:Do not use the tow/haul feature when driving in icy
or slippery conditions as the increased engine braking can cause
the rear wheels to slide and the vehicle to swing around with the
possible loss of vehicle control.
