CANADIAN/GATE OPERATOR
P
ROGRAMMING
For programming transmitters in Canada/
United States that require the transmitter
signals to “time-out” after several seconds of
transmission.
Canadian radio frequency laws require
transmitter 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.
It may be helpful to unplug the device during the
cycling process to prevent possible overheating
of the garage door or gate motor.

1. Place the ignition in the ON/RUN position.

2. Place the hand-held transmitter 1 to
3 inches (3 to 8 cm) away from the
HomeLink® button you wish to program
while keeping the HomeLink® indicator
light in view.

3. Continue to press and hold the HomeLink® button, while you press and release (cycle)
your hand-held transmitter every two seconds until HomeLink® has
successfully accepted the frequency signal.
The indicator light will flash slowly and then
rapidly when fully trained.
4. Watch for the HomeLink® indicator to change flash rates. When it changes, it is
programmed. It may take up to 30 seconds or
longer in rare cases. The garage door may
open and close while you are programming.

5. Press and hold the programmed HomeLink® button and observe the
indicator light.
NOTE:
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the
HomeLink® button is pressed.

To program the two remaining HomeLink®
buttons, repeat each step for each remaining
button. DO NOT erase the channels.

If you unplugged the garage door opener/
device for programming, plug it back in at this
time. Reprogramming A Single HomeLink® Button
(Canadian/Gate Operator)
To reprogram a channel that has been
previously trained, follow these steps:

1. Place the ignition in the ON/RUN position.

2. Press and hold the desired HomeLink®
button until the indicator light begins to
flash after 20 seconds. Do not release the
button.
3. Without releasing the button, proceed with “Canadian/Gate Operator Programming”
step 2 and follow all remaining steps

RAIN SENSING WIPERS — IF EQUIPPED
This feature senses rain or snowfall on the
windshield and automatically activates the
wipers. Rotate the end of the multifunction
lever to one of five detent positions to activate
this feature.

The sensitivity of the system can be adjusted with
the multifunction lever. Wiper delay position 1 is
the least sensitive, and wiper delay position 5 is
the most sensitive. Position 3 should be used for
normal rain conditions. Positions 1 and 2 can be
used if the driver desires less wiper sensitivity.
Positions 4 and 5 can be used if the driver
desires more sensitivity. Place the wiper switch in
the O (off) position when not using the system.

NOTE:
The Rain Sensing feature will not operate
when the wiper switch is in the low or
high-speed position.
The Rain Sensing feature may not function
properly when ice, or dried salt water is
present on the windshield.

Use of Rain-X or products containing wax or sili -
cone may reduce Rain Sensing performance.
The Rain Sensing feature can be turned on and
off using the Uconnect system
Ú
page 228.

The Rain Sensing system has protection
features for the wiper blades and arms, and will
not operate under the following conditions:
Low Ambient Temperature — When the igni-
tion is first placed in the ON position, the Rain
Sensing system will not operate until the
wiper switch is moved, vehicle speed is
greater than 0 mph (0 km/h), or the outside
temperature is greater than 32°F (0°C).
Transmission In NEUTRAL Position — When
the ignition is ON, and the transmission is in
the NEUTRAL position, the Rain Sensing
system will not operate until the wiper switch
is moved, vehicle speed is greater than
5 mph (8 km/h), or the gear selector is
moved out of the NEUTRAL position.
Remote Start Mode Inhibit — On vehicles
equipped with Remote Starting system, Rain
Sensing wipers are not operational when the
vehicle is in the remote start mode. Once the
operator is in the vehicle and has placed the
ignition switch in the RUN position, Rain
Sensing wiper operation can resume, if it has
been selected, and no other inhibit condi -
tions (mentioned previously) exist.

DIESEL MESSAGES AND WARNINGS
Diesel Particulate Filter (DPF) Messages
The Cummins diesel engine meets all diesel
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. These systems are
seamlessly integrated into your vehicle and
managed by the 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.

NOTE:
The charging system is independent from
load reduction. The charging system
performs a diagnostic on the charging
system continuously.
If the Battery Charge Warning Light is on it
may indicate a problem with the charging
system Úpage 108.
The electrical loads that may be switched off
(if equipped), and vehicle functions which can
be affected by load reduction:
Heated Seats/Vented Seats/Heated Wheel
Rear Defroster And Heated Mirrors
HVAC System
115 Volt AC Power Inverter System
Audio and Telematics System
Loss of the battery charge may indicate one or
more of the following conditions:

The charging system cannot deliver enough
electrical power to the vehicle system because
the electrical loads are larger than the capa -
bility of charging system. The charging system
is still functioning properly.

Turning on all possible vehicle electrical
loads (e.g. HVAC to max settings, exterior
and interior lights, overloaded power outlets
+12 Volts, 115 Volt AC, USB ports) during
certain driving conditions (city driving,
towing, frequent stopping).
Installing options like additional lights,
upfitter electrical accessories, audio
systems, alarms and similar devices.
Unusual driving cycles (short trips separated
by long parking periods).
The vehicle was parked for an extended
period of time (weeks, months).
The battery was recently replaced and was
not charged completely.
The battery was discharged by an electrical
load left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volt portable appli -
ances like vacuum cleaners, game consoles
and similar devices. What to do when an electrical load reduction
action message is present (“Battery Saver On”
or “Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if
possible:

Turn off redundant lights (interior or exterior).

Check what may be plugged in to power
outlets +12 Volts, 115 Volt AC, USB ports.

Check HVAC settings (blower, temperature).

Check the audio settings (volume).
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and
review specifications if any (load and Ignition
Off Draw currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).

The vehicle should have service performed if the
message is still present during consecutive trips
and the evaluation of the vehicle and driving
pattern did not help to identify the cause.
