22. Electronic Vehicle Information Center (EVIC) Red
Telltale Area
This area will display the EVIC reconfigurable red tell-
tales. For further information, refer to “Electronic vehicle
Information Center (EVIC)”.
23. Electronic Stability Control (ESC) OFF Indicator
Light — If EquippedThis light indicates the Electronic Stability Con-
trol (ESC) is off.
24. Vehicle Security Light This light will flash rapidly for approximately
15 seconds when the vehicle theft alarm is
arming. The light will flash at a slower speed
continuously after the alarm is set. The security
light will also come on for about three seconds when the
ignition is first turned on. 25. Temperature Gauge
The temperature gauge shows engine coolant temperature.
Any reading within the normal range indicates that the
engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher temperature
when driving in hot weather, up mountain grades, or when
towing a trailer. It should not be allowed to exceed the
upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“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 the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.

•Brake — If the ACC system predicts that its maximum
braking level is not sufficient to maintain the set
distance, this message will flash and a chime will
sound while ACC continues to apply its maximum
braking capacity. When this occurs, you should imme-
diately apply the brakes as needed to maintain a safe
distance from the vehicle ahead. Refer to “Adaptive
Cruise Control (ACC)” in “Understanding The Fea-
tures Of Your Vehicle” (if equipped).
• Clean Radar Sensor in the Front of Vehicle — If the
ACC system deactivates due to performance limiting
conditions. Refer to “Adaptive Cruise Control (ACC)”

CD/DVD DISC MAINTENANCE
To keep a CD/DVD in good condition, take the following
precautions:
1. Handle the disc by its edge; avoid touching thesurface.
2. If the disc is stained, clean the surface with a soft cloth, wiping from center to edge.
3. Do not apply paper or tape to the disc; avoid scratch- ing the disc.
4. Do not use solvents such as benzene, thinner, cleaners, or anti-static sprays.
5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become too high. NOTE:
If you experience difficulty in playing a particu-
lar disc, it may be damaged (i.e., scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have protection encoding. Try a known
good disc before considering disc player service.
RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being on in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the mobile phone antenna. This condition is
not harmful to the radio. If your radio performance does
not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during mobile phone operation when
not using Uconnect (if equipped).4

CLIMATE CONTROLS
The air conditioning and heating system is designed to
make you comfortable in all types of weather.
Dual-Zone Automatic Temperature Control
(ATC) — If Equipped
•The Automatic Temperature Control (ATC) allows
both driver and front passenger seat occupants to
select individual comfort settings.
• When occupants in the vehicle select an Auto mode
operation, Auto blower operation is set by using a
push button on the control unit and a comfort tem-
perature setting by using the temperature up and
down buttons.
• The system provides set-and-forget operation for op-
timum comfort and convenience.
• The system can be controlled manually, if desired. The ATC system automatically maintains the interior
comfort level desired by the driver and passenger.

Floor ModeAir comes from the floor outlets. A slight amount
of air is directed through the defrost and side
window demister outlets.
Mix Mode
Air comes from the floor, defrost and side window
demist outlets. This mode works best in cold or
snowy conditions. It allows you to stay comfortable
while keeping the windshield clear.
Defrost Mode
Air comes from the windshield and side window
demist outlets. Use Defrost mode with maximum
temperature settings for best windshield and side window
defrosting. When the defrost mode is selected, the blower
will automatically default to medium-high unless the
blower is controlled manually.
NOTE: While operating in the other modes, the system
will not automatically sense the presence of fog, mist or
ice on the windshield. Defrost mode must be manually
selected to clear the windshield and side glass.
Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the operator
to manually activate or deactivate the air conditioning
system. When in A/C mode and the ATC is set to a cool
temperature, dehumidified air flows through the air
outlets. If Economy mode is desired, press the A/C
button to turn off the A/C mode in the ATC display and
deactivate the A/C system. Also, make sure to select only
Panel, Bi-Level or Floor modes.

NOTE:
•If the system is in Mix, Floor or Defrost Mode, the A/C
can be turned off, but the A/C system shall remain
active to prevent fogging of the windows.
• If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed.
Recirculation Control
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the Recirculation control button. Re-
circulation mode should only be used temporarily. The
recirculation LED will illuminate when this button is
selected. Push the button a second time to turn off the
Recirculation mode LED and allow outside air into the
vehicle. NOTE:
In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recirculation
mode is not allowed in the Defrost modes to improve
window clearing operation. Recirculation will be dis-
abled automatically if Defrost is selected.
Operating Tips
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases,
turning the air conditioning (pressing the A/C button) on
will clear the fog. Adjust the temperature control, air
direction, and blower speed to maintain comfort.
As the temperature gets colder, it may be necessary to
direct air onto the windshield. Adjust the temperature
control and blower speed to maintain comfort. Higher

blower speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by selecting the
Defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
NOTE:In some cases during high temperature trailer
tow operation the Air Conditioning system performance
may be reduced. This is to help protect the engine from
overheating during the high load condition.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.4
