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.

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.

Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
•Above normal coolant temperatures could be experienced while
driving in a transmission gear ratio which lugs the engine. To correct
this problem, engine speed should be increased by downshifting into
the next lower gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate the vehicle with the power steering pump fluid level
below the ADD mark on the MAX. COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by your authorized dealer.
•Heavy or uneven steering efforts may be caused by low power
steering pump fluid level. Check for low power steering pump fluid
level before seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX. HOT side of the power steering reservoir dipstick, as
this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•underinflated tire(s) on any wheel(s)
•uneven vehicle loading
•high crown in center of road
•high crosswinds
•wheels out of alignment
•loose or worn suspension components.

TRANSMISSION FLUID CHECK
Allison Automatic Transmissions
See yourAllison Automatic Transmission Operator’s Manualfor
scheduled transmission fluid checks and change intervals. Your
transmission does not consume fluid. However, the fluid level should be
checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 20 miles [30 kilometers]). Verify that the
transmission fluid temperature gauge, located on the instrument cluster,
is within the normal range.
1. Drive the vehicle 20 miles (30 kilometers) or until it reaches normal
operating temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the engine running, parking brake engaged and your foot on the
brake pedal, move the gearshift lever through all of the gear ranges.
Allow sufficient time for each gear to engage.
4. Latch the gearshift lever in positionNorPand leave the engine
running.
5. Remove the dipstick, wiping it clean with a clean, dry, lint-free rag.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be
in the designated area for normal operating temperature or ambient
temperature.
If you must add transmission fluid, see yourAllison Automatic
Transmission Operator’s Manualfor the correct fluid type.Use of a
non-approved automatic transmission fluid may cause internal
transmission component damage.
Fluid levels above the safe range may result in transmission failure. An
overfill condition of transmission fluid may cause shift or engagement
concerns or possible damage.
TorqShift® Automatic Transmission
See theScheduled Maintenancechapter for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.
However, the fluid level should be checked if the transmission is not
working properly, i.e., if the transmission slips or shifts slowly or if you
notice some sign of fluid leakage.

Low Fluid Level
Do not drive the vehicle if there is
no indication of fluid on the dipstick
and the ambient temperature is
above 50°F (10°C).
Correct Fluid Level
The fluid should be checked at
normal operating temperature
196°F-216°F (91°C-102°C) on a
level surface. The normal operating
temperature can be reached after approximately 20 miles (30 kilometers)
of driving.

High Fluid Level
Fluid levels above the safe range
may result in transmission failure.
An overfill condition of transmission
fluid may cause shift or engagement
concerns and possible damage.
High fluid levels can be caused by an overheating condition.
Adjusting Automatic Transmission Fluid Levels
Note:Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick handle and also in the
Capacities and Specificationschapter.
If necessary, add fluid in
1 2pint (250 ml) increments through the filler
tube until the level is correct.
If an overfill occurs, excess fluid
should be removed by a qualified
technician.
Note:An overfill condition of transmission fluid may cause shift or
engagement concerns or possible damage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
Manual Transmissions
Note:Use of a non-approved transmission fluid may cause internal
transmission component damage.
See theScheduled Maintenancechapter for scheduled intervals for
fluid checks and changes.
Your manual transmission may be filled with an optional synthetic fluid
which allows the use of extended service intervals. A tag on the filler
plug identifies the use of the synthetic fluid.
Only use fluid that meets manufacturer specifications. SeeTechnical
specificationsin theCapacities and Specificationschapter.
