Door Ajar
Displays when the ignition is on
and any door is not completely
closed.
Electronic Locking Differential (If
Equipped) Illuminates when using the
electronic locking differential.
Engine Coolant Temperature If it illuminates when your vehicle
is moving, this indicates that the
engine is overheating. Stop your
vehicle as soon as it is safe to do so and
switch the engine off. Have your vehicle
checked as soon as possible. See Engine
Coolant Check
(page 237). idk
Engine Oil Pressure If it illuminates with the engine
running, or when you are driving,
this indicates a malfunction.
Stop your vehicle as soon as it is safe to
do so and switch off the engine. Check the
engine oil level.
Note: Do not resume your journey if it
illuminates despite the level being correct.
Have the system checked as soon as
possible.
Exhaust Brake On
(If Equipped) The exhaust brake indicator light
illuminates when you switch the
exhaust brake on.
Fasten Seatbelt Illuminates and a tone sounds
to remind you to fasten your
seatbelt. High Beam Illuminates when you switch on
the high beam headlamps. It
flashes when you use the
headlamp flasher.
Hydromax If the light illuminates and
remains on when the key is in the
on position or the engine is
running, this indicates inadequate hydraulic
booster pressure or reserve pump system
failure. Stop the vehicle as soon as
possible and have your vehicle checked.
Low Fuel Level Illuminates when the fuel level
is low or the fuel tank is nearly
empty. Refuel as soon as
possible.
Parking Brake Warning Briefly illuminates when you
switch the ignition to the on
position, with the engine off. It
also illuminates when you apply the
parking brake. If the park brake lamp does
not illuminate at these times, seek
immediate service. Vehicles with the power
parking brake option: If the park brake
warning lamp begins to blink after setting
the parking brake, this may indicate a
failure in the parking brake system. Have
the system checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
Parking Lamps Illuminates when you switch the
low beam headlamps or the
parking lamps 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). ELECTRONIC LOCKING
DIFFERENTIAL
(IF EQUIPPED)
Driver-Controlled Electronic
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 you
require extra traction, 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. WARNING:
Sudden acceleration
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 Electronic 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.

2022 F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing Rear Axle

Servicing a Vehicle with an
Electronic Locking Differential
Turn the engine off and raise all drive
wheels of the locker differential axle 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.

inspection and keep to instructions
provided by the service manual.
Hydraulic brake systems are
power-assisted. There is a great
reduction in braking capabilities
without engine assist.
• Proper fluid level. The level should be
at the bottom edge of the ring on each
reservoir fill port. Do not fill the master
cylinder to the top of the reservoir. If
fluid level requires attention to
maintain a proper master cylinder level,
this is an indication of either severe
operation (pad wear) or fluid leakage.
A more frequent and thorough brake
inspection is required.
• Brake lines, hoses and fittings. Repair
or replace brake line tubes, hoses or
fittings as required. Inspect these
components every 4,000 mi
(6,000 km) for the following.
• Lines for kinks, dents, corrosion or
rupture.
• Hoses for abrasions, kinks, soft
spots or rupture, collapse, cracks,
twists or loose frame supports.
When replacing a hose, be sure
there is adequate clearance to the
hose to avoid an abrasion to the
new hose.
• All connections for leaks.
Driveline Parking Brake WARNING: Use wheel chocks and
exercise caution when inspecting under
the vehicle. A vehicle roll-away could
result in property damage, personal injury
or death.
A qualified technician should adjust the
parking brake and keep to the instructions
in the service manual. AXLE INSPECTION
Front Axle
Maintaining the front axle alignment to
specifications is very important. A qualified
technician should check and maintain the
alignment.
Regular inspections should include:
•
Toe-in inspection and adjustment (if
necessary), particularly with radial
tires.
• Checking for proper tightness of axle
mounting U-bolt nuts, attaching or
mounting bolts and nuts.
• Checking the axle for damage, binding,
worn parts and adequate lubrication.
• Checking the kingpins for excessive
wear. Also, perform this check during
other scheduled maintenance, for
example as tire rotation or service,
wheel bearing service and alignment.
See the workshop manual for proper
procedures.
Toe-in
It is essential to maintain correct toe-in
and tire pressure for optimum tire wear.
Inspecting steer axle tires in the first
3,000– 10,000 mi (5,000– 16,000 km)
generally shows if tires are wearing
normally.
Rapid outside shoulder wear on both tires
indicates too much toe-in.
Rapid inside shoulder wear on both tires
indicates too much toe-out.
In P&D-type service, there can be a
left-to-right steer tire tread life differential
up to 40% depending on routes and other
variables.
