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 54. Be sure
to determine if the device has a rolling code, or non-rolling
code before beginning the programming process.
NOTE:Canadian Radio Frequency (RF) laws require transmitter
signals to time-out (or quit) after several seconds of trans -
mission, 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 successfully 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,
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 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” 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 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.
WARNING!
Your motorized door or gate will open and close while
you are programming the universal transmitter. Do
not program the transmitter 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 transmitter.
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.

temperatures. Once the desired temperature is
displayed, the system will achieve, and automatically
maintain, that comfort level.
3. When the system is set up for your comfort level, it is not necessary to change the settings. You will
experience the greatest efficiency by simply allowing
the system to function automatically.
NOTE:It is not necessary to move the temperature settings. The
system automatically adjusts the temperature, mode, and
fan speed to provide comfort as quickly as possible. To provide you with maximum comfort in the automatic
mode during cold start-ups, the blower fan will remain on
low until the engine warms up. The fan will engage
immediately if the Defrost mode is selected, or by
changing the front blower setting.

everyone comfortable while you keep moving ahead (If
vehicle is equipped with climate control).
Push the VR/Phone button . After the beep, say one of
the following commands:

“Set the driver temperature to 70 degrees”
 “Set the passenger temperature to 70 degrees”
Did You Know: Voice Command for Climate may only be
used to adjust the interior temperature of your vehicle.
Voice Command will not work to adjust the heated seats
or steering wheel if equipped.
OPERATING TIPS
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.
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
Úpage 368.
CAUTION!
Interior air enters the Rear Climate 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.

WIRELESS CHARGING PAD —
I
F EQUIPPED

Wireless Charging Pad

Your vehicle may be equipped with a 15W 3A Qi wireless
charging pad located inside of the storage area below the
climate controls. This charging pad is designed to
wirelessly charge your Qi enabled mobile phone. Qi is a
standard that allows wireless charging of your mobile
phone.
Your mobile phone must be designed for Qi wireless
charging. If the phone is not equipped with Qi wireless
charging functionality, an aftermarket sleeve or a
specialized back plate can be purchased from your mobile
phone provider or a local electronics retailer. Please see
your phone’s owner’s manual for further information.
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, and the ignition in the
ON/RUN position, 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 soft -
ware 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 efficiency, 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 tempera -
ture). 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.
CAUTION!
The key fob should not be placed on the charging pad
or within 6 inches (15 cm) of it. Doing so can cause
excessive heat buildup and damage to the fob. Placing
the fob in close proximity of the charging pad blocks the
fob from being detected by the vehicle and prevents the
vehicle from starting.

STARTING AND OPERATING129
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to limit the highest
available gear when the transmission is in DRIVE and ERS
mode is not active. For example, if you set the
transmission gear limit to FOURTH gear, the transmission
will not shift above FOURTH gear (except to prevent engine
overspeed), but will shift through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the transmission gear selector is in
DRIVE, the transmission will operate automatically,
shifting between all available gears. Tapping the “-” button
(on the steering wheel) will activate ERS mode, display the
current gear in the instrument cluster, and set that gear as
the top available gear. Once in ERS mode, tapping the “-”
or “+” button will change the top available gear.

Electronic Range Select (ERS)

To exit ERS mode, simply push and hold the “+” button
until the gear limit display disappears from the instrument
cluster.
When to Use TOW/HAUL Mode
Select TOW/HAUL mode when driving in conditions such
as: driving in hilly areas, towing a trailer, carrying a heavy
load, etc. This mode will improve performance and reduce
the potential for transmission overheating or failure due to
excessive shifting.

TOW/HAUL Switch

The TOW/HAUL Indicator Light will illuminate in the
instrument cluster to indicate that TOW/HAUL mode has
been activated. Pushing the switch a second time restores
normal operation. Normal operation is always the default
at engine start-up. If TOW/HAUL mode is desired, the
switch must be pushed each time the engine is started.
FOUR-WHEEL DRIVE OPERATION
QUADRA-TRAC I OPERATING
I
NSTRUCTIONS/PRECAUTIONS —
I
F EQUIPPED
The Quadra-Trac I is a single-speed (HI range only) transfer
case, which provides convenient full-time four-wheel drive.
No driver interaction is required. The Brake Traction
Control (BTC) System, which combines standard ABS and
Traction Control, provides resistance to any wheel that is
slipping to allow additional torque transfer to wheels with
traction.
NOTE:The Quadra-Trac I system is not appropriate for conditions
where 4WD LOW range is recommended Úpage 193.
1 — Shift Up “+”
2 — Shift Down “–”
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.
WARNING!
Do not use the “TOW/HAUL” feature when driving in icy
or slippery conditions. The increased engine braking
can cause the rear wheels to slide, and the vehicle to
swing around with the possible loss of vehicle control,
which may cause an accident possibly resulting in
personal injury or death.

IN CASE OF EMERGENCY303
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be serviced by
an authorized dealer.
Potential signs of vehicle overheating can be:
Temperature gauge is at HOT (H)
 Strong smell of coolant
 White smoke coming from engine or exhaust
 Coolant bottle coolant has bubbles present In the event it is observed that the temperature gauge is
moving towards or close to the HOT (H) position, you can
reduce the potential for overheating by taking the
appropriate action.

On the highways — slow down.
 In city traffic — while stopped, place the transmission in
NEUTRAL (N), but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
 If your Air Conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
 You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a supple -
ment to the radiator and aids in removing heat from the
engine cooling system.
MANUAL PARK RELEASE
To move the vehicle in cases where the transmission will
not shift out of PARK (P) (such as a depleted battery), a
Manual Park Release is available.
WARNING!
 Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
 Never add fuel when the engine is running. This is in
violation of most state and federal fire regulations
and may cause the Malfunction Indicator Light to
turn on.
 A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), as
soon as it’s safe, pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until the
pointer drops back into the normal range. If the pointer
remains on HOT (H), and you hear continuous chimes,
turn the engine off immediately and call for service.
WARNING!
You should be seated in the driver’s seat with your foot
firmly placed on the brake pedal to maintain control of
the vehicle before activating the Manual Park Release.
If possible, you should apply the parking brake.
Activating the Manual Park Release will allow your
vehicle to roll away if it is not secured or properly
connected to a tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.

IN CASE OF EMERGENCY305
To Reset The Manual Park Release:

1. Apply firm pressure to the brake pedal while seated
in the driver’s seat.

2. Pull the tether strap out again, then release it.
3. Allow the tether to retract with the lever back to its original position.
4. Verify that the transmission is in PARK (P).
5. Confirm that the tether has retracted fully and reinstall the access cover. If the access cover cannot
be reinstalled, repeat steps 1 through 4.

Tether Reinstalled

NOTE:When the lever is locked in the released position, the
tether will remain outside of the trim panel and the access
cover cannot be reinstalled.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Push and hold the lock button on the gear
selector. Then, shift back and forth between DRIVE (D) and
REVERSE (R) while gently pressing the accelerator.
NOTE:Shifts between DRIVE (D) and REVERSE (R) can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL (N) for
more than two seconds, you must press the brake pedal
to engage DRIVE (D) or REVERSE (R).
Use the least amount of accelerator pedal pressure that
will maintain the rocking motion without spinning the
wheels or racing the engine.
NOTE:Push the ESC OFF button to place the Electronic Stability
Control (ESC) system in “Partial OFF” mode, before rocking
the vehicle
Úpage 242. Once the vehicle has been freed,
push the ESC OFF button again to restore “ESC On” mode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping when you
are stuck and do not let anyone near a spinning wheel,
no matter what the speed.
CAUTION!
 Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL for
at least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of transmission failure during prolonged efforts
to free a stuck vehicle.
 When “rocking” a stuck vehicle by shifting between
DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
 Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).

4. Gently lower the tip of the wiper arm onto the glass.
Installing The Rear Wiper

1. Lift the rear wiper arm fully off the glass.

2. Insert the wiper blade pivot pin into the opening on the end of the wiper arm. Grab the bottom end of the
wiper arm with one hand, and press the wiper blade
flush with the wiper arm until it snaps into place.
3. Lower the wiper blade onto the glass.
EXHAUST SYSTEM
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition, have
the exhaust system inspected each time the vehicle is
raised for lubrication or oil change. Replace as required.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to ensure proper catalyst
operation and prevent possible catalyst damage.
NOTE:Intentional tampering with emissions control systems can
result in civil penalties being assessed against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer's specifications,
should be obtained immediately.
1 — Wiper Arm
2 — Wiper Blade
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
Úpage 287.
 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!
The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective -
ness of the catalyst as an emissions control device
and may seriously reduce engine performance and
cause serious damage to the engine.
 Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly
involving engine misfire or other apparent loss of
performance, have your vehicle serviced promptly.
Continued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
Safety
 Fuel Economy
 Tread Wear
 Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect the stability of
the vehicle and can produce a feeling of sluggish response
or over responsiveness in the steering.
NOTE:

Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
 Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal
wear patterns and reduced tread life, resulting in the need
for earlier tire replacement. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver's side B-pillar or rear edge of the driver's side door.
At least once a month:

Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual judg -
ment when determining proper inflation. Tires may look
properly inflated even when they are under-inflated.
 Inspect tires for signs of tire wear or visible damage.
Inflation pressures specified on the placard are always
“cold tire inflation pressure”. Cold tire inflation pressure is
defined as the tire pressure after the vehicle has not been
driven for at least three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of three hours. The
cold tire inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
WARNING!
Overloading of your tires is dangerous. Overloading can
cause tire failure, affect vehicle handling, and increase
your stopping distance. Use tires of the recommended
load capacity for your vehicle. Never overload them.
WARNING!
 Improperly inflated tires are dangerous and can
cause collisions.
 Underinflation increases tire flexing and can result in
overheating and tire failure.
 Overinflation reduces a tire's ability to cushion shock.
Objects on the road and chuckholes can cause
damage that result in tire failure.
Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
 Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
 Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
 Always drive with each tire inflated to the
recommended cold tire inflation pressure.
WARNING!
CAUTION!
After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the valve stem.
