Exhaust Gas
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/liftgate
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.

WARNING! (Continued)
•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.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete 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,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 117

NOTE:•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on
momentarily each time the ignition switch is turned
to ON/RUN.
• Each time the ignition is turned to ON/RUN, the
ESC system will be ON, even if it was turned off
previously.
• The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESC becomes inactive following the
maneuver that caused the ESC activation.
24. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily. The gauge pointer will likely indicate a higher tempera-
ture 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.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.

middle, and red telltales on the left.
EVIC Amber Telltales
This area will show reconfigurable amber caution tell-
tales. These telltales include:
• Low Fuel Telltale
When the fuel level reaches approximately 3.0 gal
(11.0 L) this light will turn on, and remain on until
fuel is added.

MAX A/C
For maximum cooling, when MAX A/C is selected the
A/C is turned on automatically and the air is
recirculated.
NOTE:A/C cannot be deselected when in MAX A/C
position. The LED will blink three times if the A/C
button is pushed. If your air conditioning performance
seems lower than expected, check the front of the A/C
condenser (located in front of the radiator), for an accu-
mulation of dirt or insects. Clean with a gentle water
spray from behind the radiator and through the con-
denser. Fabric front fascia protectors may reduce airflow
to the condenser, reducing air conditioning performance.
Mode Control (Air Direction)
Mode control allows you to choose from
several patterns of air distribution. You
can select either a primary mode, as
identified by the symbols, or a blend of
two of these modes. The closer the con-
trol is to a particular mode, the more air
distribution you receive from that mode.
Panel Mode
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to direct
airflow.

6. Blower Control
Blower control is used to regulate the amount of air
forced through the climate system. There are seven
blower speeds available. Adjusting the blower will cause
automatic mode to switch to manual operation. The
speeds can be selected using either hard-keys or soft-keys
as follows:
Hard-key
The blower speed increases as you turn the control
clockwise from the lowest blower setting. The blower
speed decreases as you turn the knob counter-clockwise.
Soft-key
Use the small blower icon to reduce the blower setting
and the large blower icon to increase the blower setting.
Blower can also be selected by pressing the blower bar
area between the icons.7. Climate Control OFF Button
Press and release this button to turn the Climate Control
ON/OFF.
8. Temperature Control Down Button
Push the button for cooler temperature settings. On the
touch-screen, slide the temperature bar towards the blue
arrow soft-key for cooler temperature settings.
9. Temperature Control Up Button
Push the button for warmer temperature settings. On the
touch-screen, slide the temperature bar towards the blue
arrow soft-key for cooler temperature settings.
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

•The temperature can be displayed in U.S. or Metric
units by selecting the US/M customer-programmable
feature. Refer to the “Uconnect® System Settings” in
this section of the manual.
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.
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.
Recirculation mode should only be used temporarily. The
recirculation LED will illuminate on the soft and hard
keys when either button is selected. Push either soft or hard key 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
feature may be unavailable (soft-key button greyed out)
if conditions exist that could create fogging on the inside
of the windshield. On systems with Manual Climate
Controls, the recirculation mode is not allowed in Defrost
mode to improve window clearing operation. Recircula-
tion will be disabled automatically if this mode is se-
lected. Attempting to use Recirculation while in this
mode will cause the LED in the control button to blink
and then turn off.

Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% ethylene glycol antifreeze coolant and
50% water is recommended. Refer to “Maintenance Pro-
cedures” in “Maintaining Your Vehicle” for proper cool-
ant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
Vacation/Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in
fresh air with the blower setting in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost
on the inside of the glass in very cold 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.
