PROGRAMMING HOMELINK® TO A
M
ISCELLANEOUS DEVICE
The procedure on how to program HomeLink®
to a miscellaneous device follows the same
procedure as programming to a garage door
opener Úpage 48. Be sure to determine if the
device has a rolling code, or non-rolling code
before beginning the programming process.
NOTE:

Canadian radio frequency laws require trans -
mitter signals to time-out (or quit) after several seconds of transmission, which may not be long
enough for HomeLink® to pick up the signal
during programming. Similar to this Canadian
law, some U.S. gate operators are designed to
time-out in the same manner. The procedure may
need to be performed multiple times to success
-
fully pair the device to your HomeLink® buttons.

REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that
has been previously trained, without erasing
all the channels, follow the procedure below.
Be sure to determine whether the new device
you want to program the HomeLink® button to
has a rolling code, or non-rolling code.

1. Place the ignition in the ON/RUN position,
without starting the engine.

2. Push and hold the desired HomeLink® button until the HomeLink® Indicator light
begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button , proceed with
Step 2 in “Programming HomeLink® To A
Garage Door Opener” Ú page 48, and
follow all remaining steps.
WARNING!
Your motorized door or gate will open and
close while you are programming the
universal transceiver. Do not program the
transceiver if people or pets are in the path
of the door or gate.
Do not run your vehicle in a closed garage
or confined area while programming the
transceiver. Exhaust gas from your vehicle
contains Carbon Monoxide (CO) which is
odorless and colorless. Carbon Monoxide is
poisonous when inhaled and can cause you
and others to be severely injured or killed.

When the vehicle is turned off, be sure to unplug any
equipment as to not drain the battery of the vehicle.
All accessories connected to the outlet(s) should be
removed or turned off when the vehicle is not in use
to protect the battery against discharge.

POWER INVERTER — IF EQUIPPED

If equipped, a 115 Volt (400 Watts Maximum)
inverter may be located inside the center console
towards the right hand side, just under the
Wireless Charging Pad (if equipped). This inverter
can power cellular phones, electronics and
other low power devices requiring power up
to 400 Watts. Certain high-end video game
consoles exceed this power limit, as will most
power tools.
Center Console Power Inverter Outlet

There is also a second 115 Volt (400 Watts
Maximum) power inverter located on the rear of
the center console. This inverter can power
cellular phones, electronics and other low
power devices requiring power up to 400 Watts.
WARNING!
To avoid serious injury or death:

Only devices designed for use in this type of
outlet should be inserted into any 12 Volt outlet.

Do not touch with wet hands.
Close the lid when not in use and while
driving the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the
vehicle's battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
Accessories that draw higher power
(i.e., coolers, vacuum cleaners, lights, etc.),
will discharge the battery even more
quickly. Only use these intermittently and
with greater caution.
After the use of high power draw accesso -
ries, or long periods of the vehicle not being
started (with accessories still plugged in),
the vehicle must be driven a sufficient
length of time to allow the generator to
recharge the vehicle's battery.

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 instru -
ment cluster display it is necessary to have the
emissions maintenance performed. Emissions
maintenance may include replacing the
Closed Crankcase Ventilation (CCV) filter
element. The procedure for clearing and reset -
ting 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 exclu -
sive 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 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 PM and restore the
system to normal operating condition.Exhaust System — Regeneration In Process
Exhaust Filter XX% Full — Indicates that the
DPF is self-cleaning. Maintain your current
driving condition until regeneration is
completed.

Exhaust System — Regeneration Completed —
This message indicates that the 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 malfunc -
tion. 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.
