8th = 5.0 mph (8 km/h)
9th = 5.6 mph (9 km/h) – If Equipped
NOTE:
During HDC the +/- shifter input is used for HDC
target speed selection, but will not affect the
gear chosen by the transmission. When actively
controlling HDC the transmission will shift
appropriately for the driver-selected set speed
and corresponding driving conditions.
Driver Override
The driver may override HDC activation with
throttle or brake application at any time.
Deactivating HDC
HDC will be deactivated but remain available if
any of the following conditions occur:
Driver overrides HDC set speed with throttle
or brake application.
Vehicle speed exceeds 20 mph (32 km/h)
but remains below 40 mph (64 km/h).

Vehicle is on a downhill grade of insufficient
magnitude, is on level ground, or is on an uphill
grade.

Vehicle is shifted to PARK. Disabling HDC
HDC will be deactivated and disabled if any of
the following conditions occur:
The driver pushes the HDC switch.
The driveline is shifted out of 4WD Low.
The parking brake is applied.
The driver door opens.
The vehicle is driven greater than 20 mph
(32 km/h) for greater than 70 seconds.
The vehicle is driven greater than 40 mph
(64 km/h) (HDC exits immediately).
HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and the
HDC switch has an LED icon, which offers
feedback to the driver about the state HDC is in.
The cluster icon and switch lamp will illumi -
nate and remain on solid when HDC is
enabled or activated. This is the normal oper -
ating condition for HDC.
The cluster icon and switch lamp will flash for
several seconds then extinguish when the
driver pushes the HDC switch but enable
conditions are not met.
The cluster icon and switch lamp will flash for
several seconds then extinguish when HDC
disables due to excess speed.
The cluster icon and switch lamp will flash
when HDC deactivates due to overheated
brakes. The flashing will stop and HDC will
activate again once the brakes have cooled
sufficiently.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to the
driving conditions and is responsible for
maintaining a safe vehicle speed.

(Continued)
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a
complete stop while on an incline. If the driver
releases the brake while stopped on an incline,
HSA will continue to hold the brake pressure for
a short period. If the driver does not apply the
throttle before this time expires, the system will
release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order
for HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver door must be closed.
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in
forward gear; vehicle backing uphill is in
REVERSE gear).

HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans-
mission is in PARK or NEUTRAL. For vehicles
equipped with a manual transmission, if the
clutch is pressed, HSA will remain active.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:

If disabling HSA using your instrument cluster
display, see
Ú
page 90 for further information.

If disabling HSA using Uconnect Settings, see
Úpage 228 for further information.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
WARNING!

There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement.
It is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the
vehicle under all road conditions. Your
complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a
collision or serious personal injury.

WARNING!

If you use a trailer brake controller with your
trailer, the trailer brakes may be activated
and deactivated with the brake switch. If so,
there may not be enough brake pressure to
hold both the vehicle and the trailer on a hill
when the brake pedal is released. In order to
avoid rolling down an incline while resuming
acceleration, manually activate the trailer
brake or apply more vehicle brake pressure
prior to releasing the brake pedal.

SERVICING AND MAINTENANCE379
Use of biodiesel mixture in excess of 20% can
negatively impact the fuel filter's ability to
separate water from the fuel, resulting in
high pressure fuel system corrosion or
damage.
Ethanol blends are not recommended or
approved for use with your Cummins diesel
engine.
In addition, commercially available fuel addi -
tives are not necessary for the proper opera -
tion of your Cummins diesel engine.
INTERVENTION REGENERATION
S
TRATEGY — MESSAGE PROCESS FLOW
The Cummins diesel engine meets all
Environmental Protection Agency (EPA) Heavy
Duty Diesel Engine Emissions Standards,
resulting in one of the lowest emitting diesel
engines ever produced.

To achieve these emissions standards, your
vehicle is equipped with a state-of-the-art engine
and exhaust system. The engine and exhaust
after-treatment system work together to achieve
the EPA Heavy Duty Diesel Engine Emissions
Standards. These systems are seamlessly
integrated into your vehicle and managed by the Cummins Powertrain Control Module (PCM).
The PCM manages engine combustion to allow
the exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input
or interaction on your part.
If the engine is allowed to idle or the truck is
driven on low engine speed drive cycles for more
than two hours, the system will automatically
enter an emissions operating mode that will
increase the engine idle speed to 900 RPM
(1,050 RPM for Chassis Cab). While in this mode,
which is designed to help maintain the Diesel
Particulate Filter, the engine idle speed will return
to normal when the brake pedal is applied.
A small change in engine tone or a slight change
in engine performance while accelerating may
also be noticeable at speeds below 20 mph
(32 km/h). This operating mode may last for up
to an hour of idle time, or around 20 minutes of
driving time.

Additionally, your vehicle has the ability to alert
you to additional maintenance required on your
truck or engine Ú
page 90.
DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) sometimes known
simply by the name of its active component,
UREA—is a key component of Selective Catalytic
Reduction (SCR) systems, which help diesel
vehicles meet stringent emission regulations.
DEF is a liquid reducing agent that reacts with
engine exhaust in the presence of a catalyst to
convert smog-forming nitrogen oxides (NOx)
into harmless nitrogen and water vapor
Úpage 440.
You can receive assistance in locating DEF in
the United States by calling 866-RAM-INFO
(866-726-4636). In Canada call
1–800–465–2001 (English) or
1–800–387–9983 (French)
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.
