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.

If the transmission is equipped with a ceramic clutch, you must start the
vehicle moving in first gear and engage the clutch before pressing the
accelerator at idle. Also, do not try to slip the clutch by raising engine
RPM and riding or feathering the clutch pedal since this causes erratic
engagement which can cause engine stalling and potential serious
damage to driveline components.
Clutch Brake (Non-Synchronized Transmissions) - Vehicle
Stationary
A clutch brake is used to stop transmission input shaft rotation so that
the initial first gear or reverse gear selection can be accomplished when
the vehicle is stationary and the engine is at idle speed. Clutch brake
application occurs in the last inch (25 millimeters) of clutch pedal travel.
When using the clutch brake, fully press the clutch pedal and shift the
transmission into first gear or reverse. If the transmission won’t go into
one of these gears, slowly release the clutch pedal while applying light
pressure on the transmission shift lever until it shifts into gear.
Note:After engagement of first gear,do notuse the clutch brake for
upshifting or downshifting. If you do, clutch brake life shortens and gear
selection shift efforts may increase.
Double-Clutch Procedures - Non-Synchronized Transmissions
In order to properly upshift or downshift:
1. Press the clutch pedal to disengage the clutch.
2. Shift the transmission into neutral.
3. Release the clutch pedal.
If upshifting,wait until the engine speed matches the transmission
speed of the gear you are selecting.
If downshifting,accelerate the engine until the engine speed matches
the input speed of the gear you are selecting. Press the clutch pedal
immediately and shift into the desired gear, then release the clutch
pedal.

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.
