Direction Indicator
Illuminates when you switch on
the left or right direction
indicator or when you switch on
the hazard warning flashers. If the
indicators stay on or flash faster, check for
a burned out bulb.
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 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 by an authorized
dealer immediately.
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 Illuminates to indicate normal
hydromax booster reserve
system activation when the
engine is off and the service brake pedal is
applied. This light may also illuminate
momentarily if the engine is running and
the driver turns the steering wheel fully in
one direction while braking. If the light
remains on while the engine is running, this
indicates inadequate hydraulic booster
pressure or reserve pump system failure.
Stop the vehicle as soon as possible and
seek service immediately by your
authorized dealer.
Low Fuel Level
(If Equipped) Illuminates when the fuel level
is low or the fuel tank is nearly
empty. Refuel as soon as
possible.
Parking Brake Warning Illuminates briefly 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 service
immediately. Vehicles equipped with the
power park 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. 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.

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.
120
F650750 (TBC) , enUSA, Edition date: 201804, Second-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.

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.
Follow the tire manufacturer's
recommended cold inflation pressure for
the tire size, load range (ply rating) and
steer axle loading typical for their operation
(each steer axle tire equals ½ steer axle
loading).
Special applications may warrant a setting
based on experience with the type of tire
operating loads and conditions. Radial tires
are more sensitive to toe-in setting than
bias ply tires. Fine tuning school bus
alignment to line-haul truck standards
does not drastically improve tire tread life.
STEERING SYSTEM
INSPECTION WARNING: Failure to maintain the
steering system in proper condition can
cause reduced steering ability resulting
in property damage, personal injury or
death.
Note: Have any steering problems
immediately corrected by a qualified service
technician.
Ask your service technician to examine the
steering mechanism. Only minor
adjustments may be necessary. Regular inspections should include:
•
Checking the tie rod, drag link end
clamp bolts and ball joints for proper
tightness.
• Checking for installation and spread of
cotter pins and tightness of nuts at
both ends of the tie rod and drag link.
• Checking that the pitman arm (steering
arm at steering gear) mounting is tight
and locked. Check system for leaks or
hose chafing. Repair immediately, if
necessary.
• Maintaining proper steering gear and
power steering pump lubricant levels.
• Checking steering column joint bolts
and steering linkage, particularly for
body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check
steering column joint bolt tightness every
60,000 mi (96,000 km) or annually,
whichever occurs first. Do not overtighten
the bolts.
Hydraulic System
Whenever draining and refilling the power
steering's hydraulic system for any reason,
bleed air from the system before returning
the vehicle to service. Failure to bleed the
hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware
of the proper procedures for filling and
bleeding the system.
