REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that has
been previously trained, without erasing all the
channels, proceed as follows. 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 to 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” and follow all remaining
steps.
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 (RF) 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.

NOTE:For vehicles equipped with Keyless Enter ‘n Go™,
place the ignition in the ON/RUN position. Make
sure while programming HomeLink® with the
engine on that your vehicle is outside of your
garage, or that the garage door remains open at all
times.
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 push and hold the HomeLink® button while you push 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. Push 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 pushed.
To program the two remaining HomeLink®
buttons, repeat each step for each
remaining button. DO NOT erase the chan -
nels.
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.

OPERATING TIPS
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide proper
corrosion protection and to protect against engine
overheating. OAT coolant (conforming to
MS.90032) is recommended. For more
information, see Ú page 401.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 392.
Window Fogging
Vehicle windows tend to fog on the inside in mild,
rainy, and/or humid weather. To clear the
windows, select Defrost or Mix mode and increase
the front blower speed. Do not use the
Recirculation mode without A/C for long periods,
as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of
the windshield, is free of obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control system
may automatically adjust airflow to maintain cabin
comfort. Customer settings will be maintained
upon return to an engine running condition.
Windshield Wiper De-Icer — If Equipped
The Windshield Wiper De-Icer is a heating element
located at the base of the windshield.
It operates automatically once the following
conditions are met:
Activation By Front Defrost
The Windshield Wiper De-Icer activates auto -
matically during a cold weather manual start
with full defrost, and when the ambient
temperature is below 33°F (0.6°C) .
CAUTION!
Interior air enters the Rear Automatic
Temperature Control system through an intake
grille, located in the right side trim panel behind
the third row seats. The heater outlets are
located in the right side trim panel, just behind
the rear doors. Do not block or place objects
directly in front of the inlet grille or heater
outlets. The electrical system could overload
causing damage to the blower motor.

The wireless charging pad is equipped with an
anti-slip mat to hold your mobile phone in place,
and an LED indicator light.
LED Indicator Status:
No Light: Charging pad is idle or searching for a
device.
Blue Light: Device is detected and is charging.
Red Light/Flashing: Internal error or foreign
object is detected.
Important Notes Regarding This Vehicle’s Wireless
Charging Pad:
All vehicle doors must be closed for the wireless
charging pad to operate.
If the phone moves on the pad causing the red
light to illuminate, the phone will have to be
picked up and placed back on the charging pad
to resume charging.
Wireless charging is not as fast as when the
phone is connected to a wired charger.
The phone’s protective case must be removed
when placed on the wireless charging pad.
iPhone® 12 (including iPod®) is equipped with
software to protect the device from overheating.
When the software is active, the rate of charge
is slowed down to protect the device.
Phones must always be placed on the wireless
charging pad within the outline shown on the
pad so that its charging parts connect with the charging coils of the system. Movement of the
phone during charging may prevent or slow the
rate of charge.
Having multiple applications open on the phone
while charging will reduce the charging effi
-
ciency, and may even shut down an application
that is actively running (i.e. Apple CarPlay®).
This may also cause the phone to overheat.
Wireless chargers may implement certain
methods to prevent the phone from overheating
during charging such as slowing down the rate
of charge. In certain instances, the device may
shut down for a brief period of time (when the
device reaches a certain temperature). If this
happens, it does not mean there is a fault with
the wireless charing pad. This may just be a
protective measure to prevent damage to the
phone.
WINDOWS
POWER WINDOW CONTROLS
The power window controls, located on the driver's
door trim panel, operate the window movement for
all four power windows.

200STARTING AND OPERATING
OFF-ROAD DRIVING TIPS
Quadra-Lift — If Equipped
When off-roading, it is recommended that the
lowest useable vehicle height that will clear the
current obstacle or terrain be selected. The vehicle
height should then be raised as required by the
changes in terrain.
The Selec-Terrain switch will automatically change
the vehicle to the optimized height based on the
Selec-Terrain switch position. The vehicle height
can be changed from the default height for each
Selec-Terrain mode by normal use of the air
suspension switches Úpage 131.
When To Use 4WD LOW Range —
If Equipped
When off-road driving, shift to 4WD LOW for
additional traction. This range should be limited to
extreme situations such as deep snow, mud, or
sand where additional low speed pulling power is
needed. Vehicle speeds in excess of 25 mph
(40 km/h) should be avoided when in 4WD LOW
range.
Driving Through Water
Although your vehicle is capable of driving through
water, there are a number of precautions that
must be considered before entering the water.
NOTE:Your vehicle is capable of water fording in up to
24 inches (61 cm) with air suspension or
21 inches (53 cm) without air suspension, of water
while crossing small rivers or streams. To maintain
optimal performance of your vehicle's heating and
ventilation system it is recommended to switch the
system into recirculation mode during water
fording. Be sure to avoid lowering the vehicle in
water, ensure that the easy exit entry setting is
turned off in Uconnect settings. Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your vehicle.
If you must drive through water, try to determine
the depth and the bottom condition (and location
of any obstacles) prior to entering. Proceed with
caution and maintain a steady controlled speed
less than 5 mph (8 km/h) in deep water to
minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm
run-off), avoid crossing until the water level
recedes and/or the flow rate is reduced. If you
must cross flowing water avoid depths in excess of
9 inches (23 cm). The flowing water can erode the
streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting.
WARNING!
Do not drive in 4WD LOW range on dry
pavement; driveline damage may result. 4WD
LOW range locks front and rear drivelines
together and does not allow for differential
action between the front to rear driveshafts.
Driving in 4WD LOW on pavement will cause
driveline binding; use only on wet or slippery
surfaces.
CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering as a precaution, and check all
fluids afterward. Driving through water may
cause damage that may not be covered by the
New Vehicle Limited Warranty.

SAFETY305
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.
WARNING!
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
