Engine compartment (with engine stopped)
Any leaks:
Check for signs of fluid puddles, dripping fluid
on the ground under the engine or the
underside of the engine.
HVAC air inlet:
Check for debris, leaves, etc. that may have
collected on the HVAC air inlet grille or inside
the exterior module as this may cause reduced
system performance.
Exercise great caution when working on vehicle equipped with
an automatic fan clutch. The fan starts in motion only after the
engine coolant reaches a predetermined temperature or the refrigerant
pressure (if equipped with air conditioning) reaches a predetermined
setting. The fan will start at this point with no advance warning. Never
reach near, or permit objects to protrude into, the fan blade radius
while the engine is running as this could result in vehicle damage,
personal injury or death.
Engine starting (parking brake applied)
Safety/Emergency
equipment:
Prior to entering the cab, verify that the vehicle
is equipped with spare electrical fuses (if
used), three red reflective triangles, a properly
charged and rated fire extinguisher and wheel
chocks. Walk around the vehicle and check that
all steps and grab handles, inside and out as
well as behind, are tight and clean. Use
extreme caution and a three-point stance at all
times. Check door latches for positive closing,
latching and locking.

Never adjust the steering wheel when the vehicle is moving.
AUXILIARY POWER POINT
The auxiliary power point is located
on the instrument panel.
Note:
Do not use the power point
for operating the cigarette lighter
element (if equipped).
Note:
To prevent the fuse from
being blown, do not use the power
point(s) over the vehicle capacity of
12 VDC/180W.
Note:
To prevent the battery from being discharged, do not use the
power point longer than necessary when the engine is not running.
Power points are designed for accessory plugs only. Do not hang
any type of accessory or accessory bracket from the plug.
Improper use of the power point can cause damage not covered
by your warranty.
Do not plug optional electrical accessories into the cigarette
lighter; use the power point.
POWER WINDOWS (IF EQUIPPED)
Do not leave children unattended in the vehicle and do not let
children play with the power windows. They may seriously injure
themselves.
When closing the power windows, you should verify they are free
of obstructions and ensure that children and/or pets are not in
the proximity of the window openings.
Press and hold the rocker switches to open and close windows.

AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
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 D (Direct Drive), does 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.
Hold the brake pedal down while you move the gearshift lever
between positions. If you don’t hold the brake pedal down, your
vehicle may move unexpectedly and cause property damage, personal
injury or death.
Allison 2200 with park pawl feature
Note:
For Allison automatic transmission-equipped vehicles, also refer to
the separate Allison Transmission Operator’s Manual.
A parking pawl effectively grounds the transmission’s output shaft
preventing rotation of the driveline. If the vehicle is stationary, selecting
the P (Park) position places the transmission in neutral and engages the
parking pawl (always use the parking brake, also).
Note:
If the P (Park) position is selected when the vehicle is in motion,
the parking pawl mechanism will ratchet and
NOT
hold the truck.
Always set the parking brake fully. Do not use the gearshift in
place of the parking brake.
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 P (Park). 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.

HAZARD FLASHER
The hazard flasher control is located
on the steering column, just behind
the steering wheel. The hazard
flashers will operate when the
ignition is off.
Push in the flasher control and all
front and rear direction signals will
flash. Press the flasher control again
to turn them off. Use it when your
vehicle is disabled and is creating a
safety hazard for other motorists.
Note:
With extended use, the flasher may run down your battery.
FUSING
If electrical components in the vehicle are not working, a fuse may have
blown. Blown fuses are identified by a broken wire within the fuse.
Check the appropriate fuses before replacing any electrical components.
Note:
Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

Battery tray with cover removed.
Maintenance-free batteries do not normally require adding additional
water.
Make sure the battery cover/shield is reinstalled after the battery
has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the batteries clean
and dry. Also, make certain the battery cables are always tightly fastened
to the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time. This will minimize the discharge of your battery
during storage.
If the engine cranks but does not start, remove the battery box cover
and check the 40A inline fuse located on the battery cable above the
battery.
Batteries normally produce explosive gases which can cause
personal injury. Therefore, do not allow flames, sparks or lighted
substances to come near the battery. When working near the battery,
always shield your face and protect your eyes. Always provide proper
ventilation.
When lifting a plastic-cased battery, excessive pressure on the
end walls could cause acid to flow through the vent caps,
resulting in personal injury and/or damage to the vehicle or battery.
Lift the battery with a battery carrier or with your hands on opposite
corners.
