brake warning lamp begins to blink after
setting the parking brake, this may indicate
a failure in the parking brake system. Seek
service from an authorized dealer
immediately. Driving extended distances
with the parking brake engaged can cause
brake failure and the risk of personal injury.
Powertrain Malfunction/Reduced
Power/Electronic Throttle Control
(Gasoline Engine Only)
Illuminates in the event of a
powertrain fault. Contact an
authorized dealer as soon as
possible.
Service Engine Soon The service engine soon
indicator light illuminates when
you first switch on the ignition,
before starting the engine, to check the
bulb and to indicate whether the vehicle
is ready for Inspection/Maintenance (I/M)
testing.
If the service engine soon indicator light
stays illuminated after you start the engine,
it indicates that the On-Board Diagnostics
(OBD-II) system has detected a
malfunction of the vehicle emissions
control system. WARNING
Under engine misfire conditions,
excessive exhaust temperatures
could damage the catalytic
converter, the fuel system, interior floor
coverings or other vehicle components,
possibly causing a fire. Have an authorized
dealer service your vehicle immediately. Traction Control (Diesel Engine
Only)
Illuminates and flashes slowly if
you select the Off Road or
Mud/Snow mode. It illuminates
and flashes rapidly during a traction
control event.
Trailer Anti-Lock Brake System
(ABS) Illuminates briefly when you
switch on the ignition, and only
when a PLC trailer or a PLC
diagnostic tool is connected. If the light
fails to illuminate, remains on after you
start the vehicle or continues to flash, have
the system serviced immediately.
Transmission Tow/Haul (If Equipped) Illuminates when you switch on
the tow/haul feature. If the light
flashes steadily, have the system
serviced immediately, damage to the
transmission could occur.
Two Speed Axle The Two Speed Axle indicator
comes on when you switch the
low axle range on.

GENERAL INFORMATION
WARNING
Exceeding these ratings by
overloading can cause component
failure resulting in property damage,
personal injury or death. Fluid Temperature
If the operating temperature exceeds
250°F (121°C), the rate of axle lubrication
oxidation increases and shortens the life
of the lubricant and seals, requiring axle
lubrication changes to become more
frequent to preserve the axle. Do not
consistently run extreme pressure (EP)
lubricants above
250°F (121°C).
Axle Conversions WARNING
When operating a loaded vehicle, the
driver must keep all adjustable axles
on the ground at all times, supporting
their share of the vehicle ’s load. Failure to
do so can overload other axles, tires,
wheels, springs, steering components,
brakes and frames, resulting in early
component failure, loss of vehicle control,
possible property damage and personal
injury. We do not recommend, or approve,
performing axle conversions. However, we
understand that, on occasion, others install
aftermarket add-on axles on the truck
chassis that allow operator control for
weight transfer from other axles (such as
air lift axles). LIMITED SLIP DIFFERENTIAL
(If Equipped) WARNING
If both wheels are not raised off the
ground, the one wheel that is not
raised may pull the vehicle off its
support, possibly resulting in personal
injury. This axle provides added traction on
slippery surfaces, particularly when one
wheel is on a poor traction surface. Under
normal conditions, the limited-slip axle
functions like a standard rear axle. The axle
may exhibit a slight noise or vibration
during tight turns with low vehicle speed.
This is normal behavior and indicates the
axle is working.
Both wheels must be raised off the ground
should it be necessary to operate one
wheel with your vehicle stationary.
ELECTRONIC LOCKING
DIFFERENTIAL
(If Equipped)
Driver-Controlled Locking
Differential
Note: Never use the differential lock at
vehicle speeds above
25 mph (40 km/h).
Some drive axles have a driver-controlled
differential lock. The differential lock can
lock or unlock the differential when your
vehicle is moving or stopped. When extra
traction is required, the differential lock
provides full power to both wheels.
When you lock the differential, your
vehicle ’s turning radius increases
(under-steer).
Take care to avoid sudden accelerations
when both drive wheels are on a slippery
surface.
117
F-650/750 (TBC) , enUSA, First Printing Rear Axle
WARNING
Sudden accelerations on slippery
surfaces could cause the wheels to
spin, the vehicle to turn sideways on
a crowned road surface or in a turn,
possibly resulting in loss of vehicle control
and personal injury. Activating the Locking Differential
You can lock and unlock the differential
when your vehicle is moving at a constant
speed of less than 25 mph (40 km/h) and
while the wheels are not slipping. Do not
lock the differential when your vehicle is
traveling down steep grades and when
traction is minimal.
The differential lock and differential lock
light automatically disengage at speeds
above 25 mph (40 km/h). The differential
lock remains off until either you restart your
vehicle or you turn the differential lock
switch off then back on.
Servicing a Vehicle with a Locking
Differential
Turn the engine off and raise all drive
wheels of the locker differential axle in
order to prevent your vehicle from moving
when servicing the wheels, tires or brakes.
Axles equipped with a driver-controlled
differential deliver power to both wheels
even when only one wheel is on the ground. WARNING
Failure to raise all drive wheels with
this type of differential could cause
the vehicle to move unexpectedly,
resulting in property damage, personal
injury or death. 2-SPEED REAR AXLE
(If Equipped)
WARNING
Never shift a two-speed axle when
descending a steep grade as this
may cause loss of vehicle control and
result in personal injury. Note:
Do not shift between ranges when
the speed control is on.
A two-speed rear axle allows the driver to
select a low range for greater pulling power
and a high range for greater road speed
and fuel economy. You can also use these
ranges to provide extra steps between
transmission shifts when driving on steep
grades or fuel economy may be factors.
Axle Shifting Note:
Do not shift the axle to LOW when
your vehicle is moving. Use LOW when you
drive a fully loaded vehicle on a severe grade
or in congested traffic. Use HIGH for all
normal driving conditions with a lightly
loaded or partially loaded vehicle.
Note: The axle is set to HIGH by default.
To shift the axle between HIGH and LOW
with the vehicle stopped, place the
transmission in position N, then press and
hold the button for two seconds.

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 may happen because
excessive brake applications are depleting
the system air pressure. If this condition
occurs, stop driving your vehicle until the
compressor has fully recharged the air
system.
Select a gear ratio to help slow your vehicle
before descending grades. Supplementing
with brakes, as required, help to safely slow
the vehicle and avoids 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 painted orange indicator is on
the air chamber push rod at the slack
adjuster stroke dimension that requires
service when visible during brake
application.
A qualified service technician should
perform air brake inspection and
adjustment or repairs keeping to the
instructions in the service manual.
Cam Brakes - Automatic Slack
Adjusters WARNING
Do not manually adjust the
automatic slack adjusters to correct
excessive push rod stroke as it may
result in reduced brake effectiveness and
a vehicle crash. Excessive push rod stroke
indicates that a problem exists with the
automatic adjuster, with the installation
of the adjuster, or with foundation brake
components that manual adjustment does
not remedy. Seek service from a qualified
facility for excessive push rod stroke. Standard air brakes (cam) are equipped
with automatic brake adjusters. Automatic
adjustment occurs during brake
applications. Inspect brakes for proper
adjustment at the specified intervals. See
Scheduled Maintenance
(page 316).
Emergency Air Brake WARNING
Do not continue to operate the
vehicle with a failure of one of the
brake systems. Take the vehicle to
your dealer for service immediately. All vehicles are equipped with a dual brake
system. In the unlikely event of a failure of
one system, the second system functions
for emergency stopping. The brake pedal
controls all these systems in the same
manner as for normal stops.
EXHAUST BRAKE
WARNING
The exhaust brake is not
recommended for use on slippery or
low traction road surfaces. Under
these conditions a loss of vehicle control
could occur. 124
F-650/750 (TBC) , enUSA, First Printing BrakesE206772 E210337
PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
Note:
The system does not apply the brakes
when vehicle speed is above 25 mph
(40 km/h).
USING TRACTION CONTROL -
VEHICLES WITH: AIR BRAKES WARNING
Aggressive driving in any road
conditions can cause you to lose
control of your vehicle increasing the
risk of severe personal injury or property
damage. The occurrence of a traction
control event is an indication that at least
some of the tires have exceeded their
ability to grip the road; this may lead to an
increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
If you experience a severe road event,
SLOW DOWN. Use the traction control switch on the
instrument panel to select Off Road or
Mud/Snow traction mode.
This is beneficial when your vehicle is stuck
in snow or on a slippery road surface. This
mode allows excess wheel spin to dig your
vehicle out and allows you to rock your
vehicle.
Press the switch again to select standard
traction control. The system automatically
selects standard traction control at the
next ignition cycle. System Indicator Light
Note:
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 an authorized
dealer for service.
During traction control operation, the
traction control light flashes rapidly and
the engine does not rev-up when you press
further on the accelerator. This is normal
and is no reason for concern.
In Off Road or Mud/Snow mode, the
traction control light illuminates and
flashes slowly. If a traction event occurs in
either mode, the light flashes rapidly.
USING TRACTION CONTROL -
VEHICLES WITH: HYDRAULIC
BRAKES WARNING
Aggressive driving in any road
conditions can cause you to lose
control of your vehicle increasing the
risk of severe personal injury or property
damage. The occurrence of a traction
control event is an indication that at least
some of the tires have exceeded their
ability to grip the road; this may lead to an
increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
If you experience a severe road event,
SLOW DOWN. The system automatically turns on each
time you switch the ignition on.
Use the traction control switch on the
instrument panel to switch the system off
or on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
