(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. Adjust the temperature you would like the syste

m to maintain, by adjusting the driver,
and passenger 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.
The temperature can be displayed in U.S. or
Metric units by selecting the U.S./Metric
customer programmable feature within
Uconnect Settings. To provide you with maximum comfort in the
automa
t

ic 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
knob setting.

ce

Command for Climate may
only be used to adjust the interior temperature of
your vehicle. Voice Command will not 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 Ú page 338.
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

Warning Light — If Equipped
This warning light will indicate when the
ESC system is Active. The ESC Indicator
Light
in the instrument cluster will come
on when the ignition is placed in the ON/
RUN or ACC/ON/RUN position, and when ESC is
activated. It should go out with the engine running.
If the ESC Indicator Light comes on continuously
with the engine running, a malfunction has been
detected in the ESC system. If this warning light
remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers)
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable sys -
tem operation or sensor damage may result
w hen u

sing replacement equipment that is not
of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using after -
market tire sealants may cause the Tire Pres -
sure Monitoring System (TPMS) sensor to
b ecome

inoperable. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have your
sensor function checked.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is
illuminated you could cause the fluid to boil over,
come in contact with hot engine or exhaust
components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission damage
or transmission failure.

STARTING AND OPERATING 89
these conditions, using a lower gear will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal
operat i

ng limits, the transmission controller may
modify the transmission shift schedule, reduce
engine torque, and/or expand the range of torque
converter clutch engagement. This is done to
prevent transmission damage due to overheating.
If the transmission becomes extremely hot, the
Trans m

ission Temperature Warning Light may
illuminate and the transmission may operate
differently until the transmission cools down.
During cold temperatures, transmission operation
may be
modified depending on engine and
transmission temperature as well as vehicle
speed. This feature improves warm up time of the
engine and transmission to achieve maximum
efficiency. Engagement of the torque converter
clutch, and shifts into EIGHTH or NINTH gear, are
inhibited until the transmission fluid is warm.
Normal operation will resume once the
transmission temperature has risen to a suitable
level.
AutoStick
AutoStick is a driver-interactive transmission
f eatu r

e providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall vehicle performance. This system can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing and many other situations.
Operation
When the gear selector is in the AutoStick position
(besi
d

e the DRIVE position), it can be moved
forward and rearward. This allows the driver to
manually select the transmission gear being used.
Moving the gear selector forward (-) triggers a
downshift, and rearward (+) an upshift. The current
gear is displayed in the instrument cluster.
NOTE:
In AutoStick mode, the transmission will only shift
up or d
own when the driver moves the gear
selector rearward (+) or forward (-), except as
described below:
The transmission will automatically upshift
when necessary to prevent engine overspeed.
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST or SECOND gear (depending on model)
when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as
the vehicle is accelerated.
You can start out (from a stop) in FIRST or
SECOND gear. Starting out in SECOND gear can
be helpful in snow or icy conditions. Tap the gear
selector forward or rearward to select the
desired gear after the vehicle is brought to a
stop.
If a requested downshift would cause the
engine to overspeed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Avoid using Cruise Control when AutoStick is
engaged because the transmission will not shift
automatically.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected.
To disengage AutoStick mode, return the gear
select
or to the DRIVE position. You can shift in or
out of the AutoStick position at any time without
taking your foot off the accelerator pedal.
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.

5. Remove funnel from filler pipe, clean off prior
to putting back in the spare tire storage area.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can reduce
the pot
ential for overheating your engine by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, put transmission
in NEUTRAL (N), but do not increase engine idle
speed.
NOTE:
There are steps that you can take to slow down an
impen d
ing 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.
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position, follow
the steps below:
NOTE:
A depleted battery will prevent the Electric Park
Brake
to be applied.

1. Turn the engine OFF.

2. App

ly the Electric Park Brake.
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 Malfunc -
tion 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.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads
“H”, pull over and stop the vehicle. Idle the vehi -
cle with the air conditioner turned off until the
pointe r

drops back into the normal range. If the
pointer remains on the “H” and you hear contin -
uous chimes, turn the engine off immediately
and c a

ll for service.
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 cool -
ant bottle is hot.

IN CASE OF EMERGENCY 283
(Continued)
TOWING A DISABLED VEHICLE
This section describes procedures for towing a
disabled vehicle using a commercial towing
service. Proper towing or lifting equipment is required to
preve
n

t damage to your vehicle. Use only tow bars
and other equipment designed for this purpose,
following equipment manufacturer’s instructions.
Use of safety chains is mandatory. Attach a tow bar
or other towing device to main structural members
of the vehicle, not to fascia/bumpers or associated
brackets. State and local laws regarding vehicles
under tow must be observed.
NOTE:
Vehicles with a discharged battery or total elec -
trical failure when the Electric Park Brake (EPB)
is en g
aged, will need a wheel dolly or jack to
raise the rear wheels off the ground when
moving the vehicle onto a flatbed.
You must ensure that the Auto Park Brake
feature is disabled before towing this vehicle, to
avoid inadvertent Electric Park Brake engage -
ment. The Auto Park Brake feature is enabled or
disab l

ed via the customer programmable
features in the Uconnect Settings.
If you must use the accessories (wipers,
defros t

ers, etc.) while being towed, the ignition
must be in the ON/RUN position, not the ACC
position.
If the vehicle's battery is discharged, instructions
on shif
ting the automatic transmission out of PARK
(P) in order to move the vehicle Ú page 281.
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 sec-
onds c on

tinuously 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 clutch or
transmission failure during prolonged efforts
to free a stuck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE/SECOND gear 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).

SERVICING AND MAINTENANCE 299
(Continued)
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
syste m
s can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfu n

ctioning 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
damag
e

:
Do not interrupt the ignition when the transmis -
sion is in gear and the vehicle is in motion.
Do not try to start the vehicle by pushing or
towing the vehicle.
Do not idle the engine with any ignition compo -
nents disconnected or removed, such as when
diagn os
tic testing, or for prolonged periods
during very rough idle or malfunctioning oper -
ating conditions.
COOLING SYSTEM
Coolant Checks
Check engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather,
where
applicable). If the engine coolant is dirty or
rusty in appearance, the system should be
drained, flushed and refilled with fresh engine
coolant. Check the front of the A/C condenser for
any accumulation of bugs, leaves, etc. If dirty,
clean by gently spraying water from a garden hose
vertically down the face of the condenser.
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 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.

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 radi -
ator 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 automatically 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 igni -
tion to the OFF mode. The fan is temperature
c ontroll

ed and can start at any time the igni -
tion is in the ON mode.
WARNING!

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
stabil
ity 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
resis t

ance resulting in higher fuel consumption. Tread Wear
Improper cold tire inflation pressures can cause
a
bnorm a

l 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 judgment 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.
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.
