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.

7. Remove the spout from the DEF container and install the cap back on
the bottle.
8. If the container is empty, discard the empty container and spout, or
recycle if possible. If there is some DEF left in the container, retain it
and the spout for later use. Store the spout to make sure it is kept clean.
9. Wipe away any DEF that has spilled on painted surfaces with water
and a damp cloth.
DEF Filling Station Nozzle Fill
Filling the DEF tank using a nozzle is similar to a normal fuel fill. The
nozzle shuts off automatically when the tank is full. Do not continue to
fill the tank as this may cause spillage and overfill the tank, which can
cause damage.
Filling the DEF Tank in Cold Climates
DEF freezes below 12°F (-11°C). If temperatures are at or below 12°F
(-11°C) for an extended period of time, and the DEF tank is full, and
you are not going to drive the vehicle, there is a risk that the tank could
freeze, causing damage. If low temperature conditions are expected, you
should keep your tank at least 50% full and make sure you add DEF on
level ground to prevent the fluid from freezing on an angle.
Contaminated DEF
SCR systems are sensitive to contamination of the DEF. USE ONLY
CERTIFIED DIESEL EXHAUST FLUID. If the system becomes
contaminated and the vehicle continues to be driven with contaminated
DEF, the following warnings result:

If any of these warnings appear, the contaminated DEF must be purged
and replaced with approved DEF. See an authorized dealer or the
Workshop Manual.
Upon filling the DEF tank after a DEF contaminated warning, normal
operation resumes when the vehicle is restarted.
DEF Guidelines and Information
•DEF is non-flammable, non-toxic, colorless and water-soluble.
•Use only DEF that carries the trademark: AMERICAN PETROLEUM
INSTITUTE CERTIFIED DIESEL EXHAUST FLUID.
•An ammonia odor may be smelled when the cap is removed or during
a refill. Refill the DEF tank in a well-ventilated area.
•Prior to filling the tank, make sure the surrounding area is clean of
debris to prevent contamination.
•Do not dilute DEF with water or any other liquid.
•Do not put DEF in the fuel tank or any other tank on the vehicle.
•Do not re-use the nozzle or the DEF container once it is emptied.
•Do not overfill the DEF tank.
•Avoid spilling DEF on painted surfaces, carpeting or plastic
components. Immediately wipe away any DEF that has spilled on
painted surfaces with a damp cloth and water. If it has already
crystallized, use warm water and a sponge.
•DEF freezes below 12°F (-11°C). Your vehicle is equipped with an
automatic pre-heating system which allows the DEF system to
operate below 12°F (-11°C).
•Do not store the DEF bottle in your vehicle. If it leaks, it could cause
damage to interior components or release an ammonia odor inside the
vehicle.
•Store DEF out of direct sunlight and in temperatures between
23°F–68°F (-5°C–20°C).
NOISE EMISSIONS
In order to comply with the federal exterior noise regulations, your
vehicle may be equipped with noise emission items. Depending on the
vehicle configuration, it may have all or some of the following items:
Air Intake System:Inspect the air cleaner. Do not alter its location. Do
not alter inlet and outlet piping.
Body:Inspect wheel well splash shields, cab shields and underhood
insulation for deterioration, dislocation and orientation.

MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Manual transmission shift patterns are displayed on either the shift lever
knob or the sun visor. Study this information carefully before you drive
the vehicle even though you may be familiar with similar units. Do not
attempt to drive the vehicle without knowing the exact shift pattern of
the transmission. Consult your authorized dealer if any questions exist as
to the shifting instructions posted in your vehicle.
Driving Hints
WARNING:Do not coast the vehicle with the clutch pedal
pressed or with the transmission in neutral. This practice could
result in loss of vehicle control.
The following driving hints are provided as a brief, general guide in
operating the different manual transmissions used in your vehicle.
•When shifting into first gear or reverse with your vehicle standing
still, quickly release and press the clutch pedal (if necessary to
complete gear engagement).
•Always use the lowest (or most appropriate) gear to start the vehicle.
•Always use a gear ratio low enough to allow the engine to operate
above the minimum engine operation speed range.
•Do not lug the engine.
•Do not slam or jerk the gearshift lever into gear.
•When more power is required, shift to a lower gear and accelerate
the engine near the governed speed.
To go forward, press the clutch pedal in and shift into first gear while
the engine is idling. Engage the clutch while pressing the accelerator to
start forward. Operate the clutch and upshift as required by driving
conditions.
To go backward, put the gearshift lever in reverse and engaging the
clutch while pressing lightly on the accelerator.
Shifting with a Synchronized Transmission
With the clutch pedal pressed in, use the second gear synchronizer to
stop the clutch disc rotation; this allows smooth engagement of first gear
or reverse. To complete the gear engagement, it may be necessary to
apply light pressure to the gearshift lever during initial engagement of
the clutch. It takes a second or two to match gear speeds; steady
pressure on the gearshift lever helps the synchronizer perform its job
more quickly. If the gearshift lever is forced into position, this action
defeats the purpose of the synchronizer by causing gear clash.

AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
WARNING:Hold the brake pedal down while you move the
gearshift lever between positions. If you do not hold the brake
pedal down, your vehicle may move unexpectedly and cause property
damage, personal injury or death.
Main transmission, auxiliary transmission, transfer case and power
take-off (PTO) control shift patterns can be found on a placard or decal
on the driver’s sun visor, on the instrument panel or on the shift control
itself.
The main transmission control is used to select the various gear ratios or
speeds of the transmission. Selecting positionDdoes not change the
transmission gear ratio, but is used where the gear ratios in the main
transmission are adequate to handle the vehicle operation.
If the transmission fails to shift properly, check the inline 10A fuse
located in the battery cables above the battery.
Brake-shift Interlock
Vehicles equipped with a gasoline engine have a brake-shift interlock
feature that prevents the gearshift lever from being moved from position
Pwhen the ignition is in the on position and the brake pedal is not
pressed.
If you cannot move the gearshift lever out of positionPwith the ignition
in the on position and the brake pedal pressed, it is possible that a fuse
has blown or the vehicle’s brake lamps are not operating properly. See
theFuseschapter.
WARNING:Do not drive your vehicle until you verify that the
brake lamps are working.
WARNING:When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.

WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
If the fuse is not blown and the brake lamps are working properly, the
following procedure allows you to move the gearshift lever from positionP:
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 the vehicle.
See your 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.

Position 1
•Provides maximum engine braking.
•Allows upshifts by moving gearshift lever.
•The transmission does not downshift into position1at high speeds; it
downshifts to a lower gear and then shifts into position1when the
vehicle reaches slower speeds.
Forced Downshifts
•Allowed in positionD.
•Press the accelerator to the floor.
•Allows transmission to select an appropriate gear.
Allison 2200 with Parking Pawl Feature
Note:Also see the separateAllison Transmission Operator’s Manual.
WARNING:Always set the parking brake fully. Do not use the
gearshift in place of the parking brake.
WARNING: To avoid sudden, unexpected vehicle movement
and possible personal injury or death:
1. Bring the vehicle to a complete stop.
2. Shift the transmission into positionP.Slowly lift your foot from the
brake pedal to engage the transmission parking pawl mechanism.
3. Apply the parking brake and make sure it is holding properly. Do not
rely solely on the parking mechanism of the transmission.
4. Turn the engine off when you leave the vehicle.Never leave the
vehicle unattended when the engine is running.
A parking pawl effectively grounds the transmission’s output shaft
preventing rotation of the driveline. If the vehicle is stationary, selecting
positionPplaces the transmission in neutral and engages the parking
pawl. Always use the parking brake when parking the vehicle.
Note:If positionPis selected when the vehicle is in motion, the parking
pawl mechanism ratchets andDOES NOThold the truck.
