GETTING TO KNOW YOUR VEHICLE77
NOTE:
HomeLink® is disabled when the Vehicle Secu -
rity Alarm is active. NOTE:
Only use this transceiver with a garage door
opener that has a “stop and reverse” feature as
required by federal safety standards. This
includes most garage door opener models
manufactured after 1982. Do not use a garage
door opener without these safety features. Call
toll-free 1-800-355-3515 or, on the Internet at
HomeLink.com
for safety information or assis -
tance.
Before You Begin Programming HomeLink®
Be sure that your vehicle is parked outside of
the garage before you begin programming.
For more efficient programming and accurate
transmission of the Radio Frequency (RF) signal
it is recommended that a new battery be placed
in the hand-held transmitter of the device that is
being programmed to the HomeLink® system.
To erase the channels, place the ignition in the
ON/RUN position, and push and hold the two
outside HomeLink® buttons (I and III) for up to
20 seconds or until the orange indicator
flashes. NOTE:
Erasing all channels should only be
performed when programming HomeLink®
for the first time. Do not erase channels when
programming additional buttons.
If you have any problems, or require assis
-
tance, please call toll-free 1-800-355-3515
or, on the Internet at HomeLink.com for infor-
mation or assistance.
Programming A Rolling Code
For programming garage door openers that
were manufactured after 1995. These garage
door openers can be identified by the “LEARN”
or “TRAIN” button located where the hanging
antenna is attached to the garage door opener.
NOTE:
It is NOT the button that is normally used to
open and close the door. The name and color of
the button may vary by manufacturer.
WARNING!
Your motorized door or gate will open and
close while you are programming the
universal transceiver. Do not program the
transceiver if people, pets or other objects
are in the path of the door or gate. Only use
this transceiver with a garage door opener
that has a “stop and reverse” feature as
required by Federal safety standards. This
includes most garage door opener models
manufactured after 1982. Do not use a
garage door opener without these safety
features.
Vehicle exhaust contains carbon monoxide,
a dangerous gas. Do not run your vehicle in
the garage while programming the trans -
ceiver. Exhaust gas can cause serious
injury or death.

GETTING TO KNOW YOUR INSTRUMENT PANEL125
Your vehicle has the ability to alert you to addi-
tional maintenance required on your vehicle or
engine. The following messages may display in
your instrument cluster display:
Perform Service — Your vehicle will require
emissions maintenance at a set interval. To
help remind you when this maintenance is
due, the instrument cluster display will
display “Perform Service”. When the
“Perform Service” message is displayed in
the instrument cluster display it is necessary
to have the emissions maintenance
performed. Emissions maintenance may
include replacing the Closed Crankcase
Ventilation (CCV) filter element. The proce -
dure for clearing and resetting the "Perform
Service" indicator message is located in the
appropriate Service Information.
Exhaust System — Regeneration Required
Now — "Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy" will be displayed
in the instrument cluster display if the
exhaust particulate filter reaches 80% of its
maximum storage capacity. Under conditions
of exclusive short duration and low speed
driving cycles, your Cummins diesel engine
and exhaust after-treatment system may
never reach the conditions required to
remove the trapped Particulate Matter (PM).
If this occurs, the “Exhaust Filter XX% Full
Safely Drive at Highway Speeds to Remedy”
message will be displayed in the instrument
cluster display. If this message is displayed,
you will hear one chime to assist in alerting
you of this condition
By simply driving your vehicle at highway
speeds for as little as 45 minutes, you can
remedy the condition in the particulate filter
system and allow your Cummins diesel
engine and exhaust after-treatment system
to remove the trapped Particulate Matter
(PM) and restore the system to normal oper -
ating condition.Exhaust System — Regeneration In Process
Exhaust Filter XX% Full — Indicates that the
Diesel Particulate Filter (DPF) is self-cleaning.
Maintain your current driving condition until
regeneration is completed.
Exhaust System — Regeneration Completed
— This message indicates that the Diesel
Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed, you
will hear one chime to assist in alerting you of
this condition.
Exhaust Service Required — See Dealer Now
— This message indicates regeneration has
been disabled due to a system malfunction.
At this point the engine Powertrain Control
Module (PCM) will register a fault code, the
instrument panel will display a MIL light.
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.
CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with
continued operation.

SAFETY151
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.
Hill Start Assist (HSA)
The Hill Start Assist (HSA) system 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 pres -
sure 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 park 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 (R) gear).
HSA will work in REVERSE gear and all
forward gears. The system will not activate if
the transmission is in PARK or NEUTRAL (N).
For vehicles equipped with a manual trans
-
mission, if the clutch is pressed, HSA will
remain active.
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.
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.

152SAFETY
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, refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel”
for further information.
If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Multimedia”
for further information.
For vehicles not equipped with an instrument
cluster display, perform the following steps:

1. Center the steering wheel (front wheels pointing straight forward).

2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left. 6. Push the “ESC OFF” button located in the
lower switch bank below the climate control
four times within 20 seconds. The “ESC OFF
Indicator Light” should turn on and turn off
two times.
7. Rotate the steering wheel back to center and then an additional slightly more than
one-half turn to the right.
8. Place the ignition in the OFF mode and then back to ON. If the sequence was completed
properly, the “ESC OFF Indicator Light” will
blink several times to confirm HSA is
disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
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 pres -
sure 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 acti -
vate the trailer brake or apply more vehicle
brake pressure prior to releasing the brake
pedal.
HSA is not a parking brake. Always apply
the parking brake fully when exiting your
vehicle. Also, be certain to place the trans -
mission in PARK.
Failure to follow these warnings can result
in a collision or serious personal injury.
