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:

Cooling System:
•Inspect the fan for blade damage. If damage is found, replace with
the recommended parts. Inspect for fan-to-shroud interference and
any damage to shroud, such as cracks and holes.
•Do not change fan ratio or alter fan spacer dimensions and positions.
•Inspect fan clutch for proper operation. Make sure the fan is
disengaged when cooling of the engine is not required.
•Inspect radiator shutters (if equipped) for proper operation. The
shutters should be open during normal operating temperatures.
Engine:Valve covers and block covers are made to damp-out engine
mechanical noise and, if needed, should be replaced with recommended
parts. Check for mechanical isolations.
Transmission Enclosure:Inspect for cracks, holes and tears. Clean any
deposits, such as oil, dirt and stones.
Exhaust System:
•Inspect for leaks at various joint connections and loose clamps.
•Perform a visual inspection for cracks or holes in the muffler and tail
pipe.
•Always use the recommended parts when items need to be replaced.
•Do not change the tail pipe elbow or offset tail pipe orientation from
the standard position as originally received.
•To avoid abnormal changes in vehicle sound levels, it is necessary for
the owner to perform inspections and necessary maintenance at the
intervals shown in theScheduled Maintenancechapter.

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.

Shifting with a Non-Synchronized Transmission
SeeClutch brakeandDouble clutch proceduresin theClutchsection
of this chapter.
Clutch
Do not ride or slip the clutch as this causes unnecessary heat and wear.
Maintain the specified clutch adjustment to prolong its life and regularly
inspect the clutch control linkage for tightness. See theScheduled
Maintenancechapter for other maintenance information. When
adjustment of the clutch is necessary, it is very important that the work
be performed properly or early clutch failure may result and a costly
clutch overhaul may become necessary. Clutch work should only be
performed by a qualified technician.
Note:Continued use of a damaged or worn clutch, prolonged clutch
slippage or downshifting at excessive speeds can result in a failure of the
engine, transmission or clutch components.
Note:To avoid premature clutch wear and failure, do not drive with
your foot resting on the clutch pedal or use it to hold the vehicle at a
standstill on an upgrade as when waiting for a traffic light.
Engaging the Clutch
•Always start in the proper gear.An empty vehicle can start in a
higher gear than a fully-loaded vehicle. Starting in too high a gear can
cause clutch slippage and excessive heat and wear on the clutch. A
gear that starts the vehicle moving at idle speed is the correct gear. If
the engine has to be revved to get the vehicle going, the gear
selection is too high.
•Do not shift until the vehicle has reached the proper speed.
Upshifting before the vehicle has reached the proper speed can cause
clutch slippage and excessive heat and wear on the clutch.
•Never hold a vehicle on a grade with the clutch.This causes the
clutch to slip and can actually burn up the clutch.
•Never coast with the clutch disengaged.The high RPM
(sometimes over 10000) can actually burst the facing material of the
clutch.
•Never engage the clutch while coasting.Re-engaging the clutch
after coasting may not only cause a great shock to the clutch, but the
whole drivetrain. Internal engine damage or clutch and flywheel
failure can result from this.
