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.

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:
The stability and
traction control light illuminates steadily
if the system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead
to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death. Press the TCS Off button on the
instrument panel to enable the
mud/snow mode.
This is beneficial when your vehicle is stuck
in snow or on a slippery road surface. This
mode allows 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 Mud/Snow mode, the TCS OFF light
illuminates on the instrument cluster. If a
traction event occurs in either mode, the
Stability Control and Traction Control 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 traction control
activating 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 turns on each time you switch
the ignition on.

Use the traction control button
on the instrument panel to
switch the system off or on.
If your vehicle is stuck in mud or snow,
switching traction control off is beneficial
as this allows the wheels to spin.
Press the button again to switch the
traction control system on.
System Indicator Light
Note: If the traction control light does not
flash during a traction control event or stays
on, the system is not operating. Have the
system checked as soon as possible.
During a traction control event, the traction
control light rapidly flashes. Pressing
further on the accelerator does not cause
the engine to rev higher. This is normal and
is no reason for concern.
When the system turns the traction control
off, the OFF light illuminates on the
instrument cluster. If a traction event
occurs in either mode, the stability control
and traction control light rapidly flashes.

PRINCIPLE OF OPERATION -
VEHICLES WITH: HYDRAULIC
BRAKES
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It's always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could reduce the operator's ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system turns on each time you switch
the ignition on.
If a fault occurs in either the stability
control or the traction control system, the
following conditions are possible:
• The stability and traction control light
illuminate.
• The stability control and traction
control systems are not maintaining
traction of the wheels.
If a driving condition activates either the
stability control or the traction control
system, the following conditions are
possible:
• The stability and traction control light
flash.
• Your vehicle slows down.
• The system reduces engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal could move as the system
applies higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system assists in preventing skids or
lateral slides by applying the brakes to one
or more of the wheels individually and, if
necessary, decreases engine power.

•
The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes rapidly.
• Your vehicle slows down.
• Reduced engine power.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s motion and the rate at which it
changes by applying the brakes to one or
more wheels individually.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 142). Vehicle without stability control

The set speed does not erase.
Resuming the Set Speed
Press and release the button.
Your vehicle speed returns to the
previously set speed and gap setting. The
set speed displays continuously in the
information display when the system is
active.
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). The
information display indicates low engine
speed, an audible alarm sounds and the
automatic braking releases if the vehicle
drops below this speed.
Automatic cancellation can also occur
when:
• The tires lose traction.
• You apply the parking brake.
Note: If the engine speed drops too low, an
audible warning sounds and a message
appears in the information display.
Automatic braking releases.
Hilly Condition and Trailer Tow
Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep
grades, for example in mountainous areas.
The system needs additional engine
braking in these situations to reduce the
load on the vehicle ’s regular brake system
to prevent it from overheating. Note:
An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
Note: When towing with adaptive cruise
control, switch on Tow/Haul Mode and
Diesel Engine Brake.
Switching Adaptive Cruise Control
Off Press and release the button
when the system is in standby
mode, or switch the ignition off.
Note: You erase the set speed and gap
setting when you switch the system off.
Detection Issues WARNING: On rare occasions,
detection issues can occur due to the
road infrastructures, for example bridges,
tunnels and safety barriers. In these
cases, the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening,
if required. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible.
The radar sensor has a limited field of
view. It may not detect vehicles at all or
detect a vehicle later than expected in
some situations. The lead vehicle graphic
does not illuminate if the system does not
detect a vehicle in front of you.
