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.
• 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 61

3. When the system is set up for your comfort level, it isnot necessary to change the settings. You will experi-
ence 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 US/M customer-programmable
feature. Refer to the “Uconnect™ Access System Set-
tings” 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 humid-
ity, 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
blower control knob 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 Defrost mode to improve window
clearing operation. Recirculation will be disabled auto-
matically if these modes are selected.
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
196 UNDERSTANDING YOUR INSTRUMENT PANEL

against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant 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 ensureadequate 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.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, can cause
odor, and if they enter the plenum they could plug the
water drains. In Winter months make sure the air intake
is clear of ice, slush and snow.

HAZARD WARNING FLASHER
The Hazard Warning flasher switch is located in the
center of the instrument panel above the climate controls.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flasher.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flasher will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flasher
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
• On the highways — Slow down and use the highest
gear possible.
• In city traffic — While stopped, put the transmission
in NEUTRAL, but do not increase engine idle speed.
• In city traffic — While moving, shift into the highest
gear possible to reduce engine RPM.
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.
258 WHAT TO DO IN EMERGENCIES

•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.
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.
TIREFIT KIT
Small punctures up to ¼” (6 mm) in the tire tread can be
sealed with TIREFIT. Foreign objects (e.g., screws or
nails) should not be removed from the tire. TIREFIT can
be used in outside temperatures down to approximately
-4°F (-20°C).
This kit will provide a temporary tire seal, allowing you
to drive your vehicle up to 100 miles (160 km) with a
maximum speed of 55 mph (88 km/hr).
