Engine Starting (Parking Brake Applied)
Air BrakesVerify operation using the following procedure.
Chock the wheels, if necessary. Push in the
parking brake and, on tractors, push in the
tractor parking brake knob:
1. Verify the air compressor or governor cut-out
pressure is approximately 120 psi (827 kPa).
2. Turn off the engine, then turn the key back to
the on position (without starting the engine).
3. Without the brake pedal applied, note the air
pressure drop for one minute. It should be less
than 2 psi (14 kPa) for single vehicles and 3 psi
(21 kPa) for combination vehicles.
4. Press and hold the brake pedal with 90 psi
(621 kPa) or more. Make sure there is no more
than a 3 psi (21 kPa) per minute leak for single
vehicles and a 4 psi (28 kPa) per minute leak for
combination vehicles.
5. Pump the brake pedal to deplete the system of
air pressure. The warning light and chime should
activate at 57 psi (393 kPa).
6. Pump the brake pedal and make sure the
parking brake and trailer parking brake knobs
pop out at 20 psi (138 kPa) or higher.

Trailer
If you are pulling a trailer, an inspection of the trailer similar to that of
the tractor should be done. The inspection should follow trailer
manufacturer recommendations and should include at a minimum:
general condition, landing gear, doors, sides, lights, reflectors,
suspension, brakes, tires, wheels, cargo placement, stability and
tie-downs.
Transmission
WARNING:If the unit starts in gear and/or the neutral start
switch is not functioning correctly, the vehicle may inadvertently
move which could result in property damage, personal injury or death.
If your vehicle is equipped with an automatic transmission, regularly
inspect the transmission’s neutral start switch. The engine should only
start in positionNorP.
Inspect the transmission fluid level and shift linkage for proper
operation.

Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle should stay in the normal
operating range. If the needle falls below the normal range, stop the
vehicle, turn off the engine and check the engine oil level. Add oil if
needed. If the oil level is correct, have your vehicle checked at your
authorized dealer.

Engine Coolant Temperature Gauge
Indicates engine coolant temperature. At normal operating temperature,
the level indicator is in the normal range. If the engine coolant
temperature exceeds the normal range, stop the vehicle as soon as safely
possible, switch off the engine and let the engine cool.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
Transmission Fluid Temperature Gauge
Indicates transmission fluid temperature. At normal operating
temperature, the level indicator is in the normal range. If the
transmission fluid temperature exceeds the normal range, stop the
vehicle as soon as safely possible and verify the airflow is not restricted,
such as snow or debris blocking airflow through the grill. Also, higher
than normal operating temperature can be caused by special operation
conditions (i.e., snowplowing, towing or off-road use). Operating the
transmission for extended periods of time with the gauge in the higher
than normal area may cause internal transmission damage. Altering the
severity of the driving conditions is recommended to lower the
transmission temperature into the normal range. If the gauge continues
to show high temperatures, see your authorized dealer.
Fuel Gauge
Indicates approximately how much fuel is left in the fuel tank (when the
ignition is on). The fuel gauge may vary slightly when the vehicle is in
motion or on a grade. The fuel icon and arrow indicates which side of
the vehicle the fuel filler door is located.
Information Display
Odometer:Located in the bottom of the information display. Registers
the accumulated distance your vehicle has travelled.

Diesel Exhaust Fluid (diesel engine only)
It illuminates when the diesel exhaust fluid level falls below
0.5 gallons (1.9L) in the five gallon (19.0L) tank or one gallon
(3.8L) in the nine gallon (34.0L) tank. Refill the tank or, at a
minimum, add at least one gallon (3.8L) to the five gallon (19.0L) tank
or two gallons (7.6L) to the nine gallon (34.0L) tank.
Diesel Particulate Filter (diesel engine only)
It illuminates when the soot level in the diesel particulate filter
has reached a point where it requires operator assistance. See
Diesel particulate filterin theMaintenancechapter, and your
engine operator’s manual, for more details.
Do Not Shift (Allison automatic transmission only)
It illuminates while driving if a problem has been detected in
the transmission; shifting may be restricted. Depending on the
severity of the problem, the shifter’s digital read-out may turn
blank.
Operation may continue in order to reach service assistance. The control
unit may not respond to shift selector requests, since operating
limitations are being placed on the transmission (i.e. upshifts and
downshifts may be restricted). Direction changes do not occur.
Direction Indicator
It illuminates when the left or right turn signal or the hazard
warning flasher is switched on. If the indicators stay on or flash
faster, check for a burned out bulb.
Electronic Locking Differential
It illuminates when using the electronic locking differential.
Engine Oil Pressure (gasoline engine only)
It illuminates when engine oil pressure is low.
Fasten Safety belt
It illuminates and a chime sounds to remind you to fasten your
safety belt.

Allison 3000 Series Push-Button Shifter
To shift to Reverse or Drive:
1. Press the brake pedal.
2. Press R or D on the shifter.
3. Release the brake pedal.
To select a higher range when in
Drive, press the up arrow button.
To select a lower range when in
Drive, press the down arrow button.
To place the transmission in Neutral,
press N.
Allison 3000 Prognostics
This transmission is equipped with the Allison Prognostics feature that
can alert the driver to needed transmission maintenance and
transmission fluid and filter life. See the separate Allison transmission
manual for complete details.
POWER TAKE-OFF (PTO) OPERATION (IF EQUIPPED)
A PTO unit allows the transmission to power auxiliary equipment to run
devices such as snowplows, aerial lifts, tow truck lifts, cement mixers or
dump trucks.
Vehicles Equipped with an Allison Automatic Transmission
(Except 3000 Series)
The PTO can be operated while the vehicle is standing or moving.
To engage the PTO, apply the brakes and shift to any gear other than
positionN,then engage the PTO.
If engagement is prevented by the gear teeth not meshing properly,
release the brakes and allow the vehicle to creep slightly or shift the
