Recirculation
In cold weather, use of Recirculation mode may
lead to excessive window fogging. The
Recirculation feature may be unavailable
(button on the touchscreen greyed out) if
conditions exist that could create fogging on the
inside of the windshield.
On systems with Manual Climate Controls, if
equipped, the Recirculation mode is not
allowed in Defrost mode to improve window
clearing operation. Recirculation is disabled
automatically if this mode is selected.
Attempting to use Recirculation while in this
mode causes the LED in the control button to
blink and then turns off.
AUTOMATIC TEMPERATURE CONTROL
(ATC)
Automatic Operation

1. Push the AUTO button on the faceplate, or
the AUTO button on the touchscreen on the
Automatic Temperature Control (ATC)
Panel.
2. Next, adjust the temperature that you would
like the system to maintain by adjusting the
driver and passenger temperature control
buttons. 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 for cold or hot vehicles. The system
automatically adjusts the temperature,
mode, and blower speed to provide comfort
as quickly as possible.
The temperature can be displayed in U.S. or
Metric units by selecting the U.S./Metric
customer-programmable feature. Refer to
the “Uconnect Settings” in “Multimedia” for
further information. 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 blower will increase in speed
and transition into Auto mode.
Manual Operation Override
This system offers a full complement of manual
override features. The AUTO symbol in the front
ATC display will be turned off when the system
is being used in the manual mode.
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. Organic Additive
Technology (OAT) coolant (conforming to
MS.90032) is recommended.

Programming A Non-Rolling Code
For programming garage door openers
manufactured before 1995.

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. Press and hold the HomeLink® button you want to program while you press and hold
the hand-held transmitter button.
4. Continue to hold both buttons and observe the indicator light. The HomeLink®
indicator will flash slowly and then rapidly
after HomeLink® has received the
frequency signal from the hand-held
transmitter. Release both buttons after the
indicator light changes from slow to rapid.
5. Press and hold the programmed HomeLink® button and observe the
indicator light.
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 Home -
Link® buttons, repeat each step for each
remaining button. DO NOT erase the
channels.
Reprogramming A Single HomeLink® Button
(Non-Rolling Code)
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 “Programming A Non-Rolling Code” step 2
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 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.

TOWING TIPS
Before setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission
Select the DRIVE range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control to manually
select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
under heavy loading conditions will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
This action will also provide better engine
braking.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down -
shifts. For example, choose “5” if the desired
speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase
engine idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.
1 — Battery
2 — Backup Lamps
3 — Right Stop/Turn
4 — Electric Brakes
5 — Ground
6 — Left Stop/Turn
7 — Running Lamps

242IN CASE OF EMERGENCY
3. Disconnect the positive (+) end of the
jumper cable from the positive (+) post of
the booster battery.
4. Disconnect the opposite end of the positive (+) jumper cable from the remote positive
(+) post of the vehicle with the discharged
battery.
If frequent jump starting is required to start your
vehicle you should have the battery and
charging system inspected at an authorized
dealer.IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
NOTE:
There are steps that you can take to slow down
an impending overheat condition:
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 supplement to the
radiator and aids in removing heat from the
engine cooling system.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices,
etc.). Eventually, if plugged in long enough
without engine operation, the vehicle’s
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
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), 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.

IN CASE OF EMERGENCY245
(Continued)
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 over -
heating 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).
CAUTION! (Continued)

280SERVICING AND MAINTENANCE
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.
To minimize the possibility of catalytic converter
damage:
Do not shut off the engine or interrupt the
ignition when the transmission is in gear and
the vehicle is in motion.
Do not try to start the engine by pushing or
towing the vehicle.
Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunc
-
tioning operating conditions. NOTE:
The vehicle exhaust system may be equipped
with an Electronic Exhaust Valve (EEV) system,
if the exhaust system is replaced with after
-
market products a Malfunction Indicator Lamp
(MIL) will illuminate.
COOLING SYSTEM
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri -
ously 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 malfunc -
tion, 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.
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
open a cooling system pressure cap when the
radiator or coolant bottle is hot.

Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts automati -
cally and may start at any time, whether the
engine is running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the
ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.
