Starting the engine
WARNING:Operation of a diesel engine near flammable vapors
in the air may cause the engine speed to increase uncontrollably
and over speed. If this situation occurs, mechanical damage, fire,
explosion, personal injury or death could result.Turning off the
ignition key will not slow or stop the engine due to uncontrollable
fueling of the engine through flammable vapors being drawn into
the engine air inlet.Operation of components such as starter,
alternator, electric motors, etc. and static electricity could also ignite
flammable vapors.
Do not operate the truck in the possible presence of flammable vapors
unless both a complete hazard analysis is performed and necessary
additional safety processes and/or equipment such as vapor testing, air
intake shutoff devices, ventilation, etc. are utilized. The operator is
responsible for using those processes and/or equipment to ensure that
the diesel engine and all other components on the truck can be
operated safely under the specific conditions and hazards that may be
encountered.
Note:If equipped with Eaton UltraShift transmission, allow UltraShift to
power up before starting the engine. Engine cranking is delayed until the
transmission power up is complete and the gear display shows a solid N.

WARNING:Do not drive with your foot resting on the brake
pedal. This will result in abnormally high brake temperatures,
excessive lining wear and increased stopping distances.
Before descending a long or steep hill, shift to a lower gear and avoid
continuous application of the brakes. Normally, choose the same gear to
descend the hill that you would use to ascend the hill.
WARNING:Continuous application of the brakes will cause the
brakes to overheat, resulting in a temporary loss of braking.
If brakes do not grip well
•If you have been driving through deep water, gently apply the brakes
several times while the vehicle is moving slowly.
•Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high speed stops.
•Check brake adjustment.
•Check brake linings for excessive wear.
•Check system air pressure. (Air brakes only)
HYDRAULIC BRAKES (IF EQUIPPED)
Full power brake system
The Full Power Brake System incorporates standard braking, Anti-lock
Braking (ABS), and optional Power Park Brake into one fully integrated
hydraulic brake system. With the Full Power Brake System, braking
energy is stored, similar to an air brake system, resulting in faster
response times and shorter stopping distances. This is accomplished
using motor/pump assemblies that pressurized the system by pumping
brake fluid into accumulators. This is similar to the air compressor of an
air brake system pressurizing the air tanks. The system includes a master
cylinder that provides the normal pedal “feel” and transfers the pedal
force, via brake fluid, to the main components of the Full Power Brake
System.
Note:The motor/pumps will run momentarily with the ignition switch in
the on or run positions or the switch is in the off position and the brake
pedal is pressed.

The parking BRAKE warning lamp
in the instrument cluster illuminates
and will remain illuminated (when
the ignition is turned on) until the
parking brake is released.
Push the palm release lever on the
parking brake handle and push
down as far as possible to release
the brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
WARNING:If the parking
brake is fully released but
the parking brake warning lamp
remains illuminated, the brakes
may not be working properly. See
your dealer or a qualified service
technician.
The parking brake is not
recommended to stop a moving vehicle. However, if the normal brakes
fail, the parking brake can be used to stop your vehicle in an emergency.
Since the parking brake only applies retardation to the rear wheels, the
vehicle’s stopping distance will increase greatly and the handling of your
vehicle will be adversely affected.
POWER PARK (PARKING BRAKE) OPTION (IF EQUIPPED)
This feature uses a brake chamber mounted on the chassis to power a
spring-applied, hydraulic-released driveline parking brake. It is controlled
by a yellow, dash-mounted parking brake knob.
The Power Park Brake is controlled by the park brake dash-mounted,
yellow knob-type switch. The switch has three positions: apply (out),

WARNING:Hold the brake pedal down while moving the
gearshift lever from position to position. If the brake pedal is not
held down, the vehicle may move unexpectedly resulting in property
damage, personal injury or death.
Parking brake light illumination due to low air pressure
If at any time during vehicle operation air pressure is too low, the
parking brake may apply and the parking brake light will turn on.
If the parking brake is applied due to low air pressure, immediate service
is required to the parking brake system.
Parking brake warning system
If the parking brake warning light blinks and a chime sounds when
pulling the yellow control knob out, this indicates the parking brake is
not functioning properly; seek service for the parking brake immediately.
With the ignition key not in the run position:
•A chime will sound if the park brake remains released (or in an
unknown state). The chime will extinguish in approximately eight
minutes or until the parking brake is applied. Seek service for the
parking brake immediately.
Parking brake light operation (light only works when the ignition key is
in the run position):
•On - Parking brake applied
•Off - Parking brake released and no faults/malfunctions
•Blink and chime - Parking brake released (or unknown) and
faults/malfunctions exist
Releasing spring manually
WARNING:Do not attempt to disassemble the parking brake
chamber under any circumstances. The high spring load may
cause serious injury.
If hydraulic pressure is released from the spring brake chamber the
power spring applies the brake and, unless hydraulic pressure can be
re-established, the spring brake must be released as follows in order to
move the vehicle.

WARNING:Avoid repeated light application of the brake pedal.
This will deplete air pressure faster and could result in loss of
braking capability.
Periodically check the air pressure
gauge while driving. Pressure should
range between approximately
100–125 psi (690–862 kPa). The air
compressor governor cut-in and
cut-out pressure settings are preset
at the factory and are not
adjustable.
When air pressure is insufficient
(below 60 psi [414 kPa]), a warning
light illuminates and a buzzer
sounds when the ignition is in the
on position.
This condition may be caused by excessive brake applications depleting
the system air pressure. If this condition occurs, stop driving the vehicle
until the compressor has fully recharged the air system.
WARNING:Do not move the vehicle when the air pressure is
insufficient because the brake system may be inoperative.
Select a gear ratio to help slow your vehicle before descending grades.
Supplement with brakes as required to safely slow the vehicle and avoid
overspeeding the engine.
Air chamber stroke indication
Air chamber push rods have orange stroke indicator markers that warn
when the braking system requires adjustment or repair. The orange
stripe is painted on the air chamber push rod at the slack adjuster stroke
dimension which requires service when visible during brake application.
Air brake inspection and adjustment or repairs should be performed by a
qualified service technician in accordance with the instructions in the
service manual.

Parking brake control (knob)
Pull the yellow parking brake knob
out to apply the parking brake. Push
the knob in to release the parking
brake.
WARNING:This control is
used for parking only. Do
not leave the vehicle unattended
after setting the parking brake
without placing the transmission
in R (Reverse) for manual
transmission, N (Neutral) for
automatic transmission (except
Allison 2200 transmission) or P
(Park) (Allison 2200
transmission). Use of wheel
chocks is also recommended in
hilly or off-road usage.
The parking BRAKE warning light in
the instrument cluster illuminates
and remains illuminated (when the
ignition is turned to the on position)
until the parking brake is released.
Releasing spring brake with air pressure
The air system in all vehicles with spring-actuated rear wheel parking
brakes is equipped with a tank valve located on the supply or service air
tank for connection to an outside air supply. The valve permits the
system to be recharged with air from an outside source, releasing the
spring-actuated parking brakes. The vehicle may then be towed in an
emergency.
An outside air source can be used only if the protected system is in
operating condition. If air pressure cannot be restored in the protected
air system, the spring-actuated brakes must be released manually.

ANTI-LOCK BRAKE SYSTEM (ABS)
A noise from the hydraulic pump motor and pulsation in the pedal may
be observed during ABS braking events. Pedal pulsation coupled with
noise while braking under panic conditions or on loose gravel, bumps,
wet or snowy roads is normal and indicates proper functioning of the
vehicle’s ABS. If the vehicle has continuous vibration or shudder in the
steering wheel while braking, the vehicle should be inspected by a
qualified service technician.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensating for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS-equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.
ABS warning light
The
ABSwarning light in the instrument cluster momentarily illuminates
when the ignition is turned on and the engine is off. If the light does not
illuminate momentarily at start up, remains on after the vehicle reaches
5–10 mph (8–16 km/h), or continues to flash, the ABS needs to be
serviced.
With the ABS light on, the anti-lock brake system is disabled and normal
braking is still effective unless the brake warning light also remains
illuminated. (If your parking brake warning light illuminates, have your
vehicle serviced immediately.)
Using ABS
•In an emergency or when maximum efficiency from the ABS is
required, apply continuous full force on the brake. The ABS will be
activated immediately, thus allowing you to retain full steering control
of your vehicle and, providing there is sufficient space, will enable you
to avoid obstacles and bring the vehicle to a controlled stop.
•The ABS does not decrease the time necessary to apply the brakes or
always reduce stopping distance. Always leave enough room between
your vehicle and the vehicle in front of you to stop.

•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
TRACTION CONTROL (IF EQUIPPED)
Your vehicle may be equipped with a traction control system. This
system helps you maintain the stability and steerability of your vehicle,
especially on slippery road surfaces such as snow- or ice-covered roads
and gravel roads, by reducing engine power and/or selectively applying
the rear brakes. The system will allow your vehicle to make better use of
available traction in these conditions.
Note:The traction control system will not apply the brakes when the
vehicle speed is above 25 mph (40 km/h).
During traction control operation,
the traction control light in the
instrument cluster will flash rapidly
and the engine will not “rev-up”
when you press further on the
accelerator. This is normal system
behavior and should be no reason
for concern. If the traction control
light does not flash during a traction control event or stays illuminated,
the system is not functioning properly, take your vehicle to your dealer
for service.
When the traction control switch,
located on the instrument panel, is
activated standard traction control
will change to Off Road or
Mud/Snow traction mode, the
traction control light will be
illuminated and flash slowly. If a
traction event occurs, in either
mode the traction control light will
flash rapidly. The standard traction
control can be selected by pressing
the traction control switch again or will be automatically selected at next
ignition cycle.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching to the Off Road or Mud/Snow traction control
mode. This may allow excess wheel spin to “dig” the vehicle out and
enable a successful “rocking” maneuver.
