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/
rear doors 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.
100 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Heated Seats — If Equipped
On some models, the front driver and passenger seats
may be equipped with heaters in both the seat cushions
and seatbacks.
There are two heated seat switches that allow the driver
and passenger to operate the seats independently. The
controls for each seat are located on a switch bank near
the bottom center of the instrument panel.
You can choose from HI, LO or OFF heat settings. Amber
indicator lights in each switch indicate the level of heat in
use. Two indicator lights will illuminate for HI, one for
LO and none for OFF.Push the switch once to select HI-level heating.
Push the switch a second time to select LO-
level heating. Push the switch a third time to
shut the heating elements OFF. When the HI-level setting is selected, the heater will
provide a boosted heat level during the initial stages of
operation. Then, the heat output will drop to the normal
HI-level. If the HI-level setting is selected, the system will
automatically switch to LO-level after approximately 30
minutes of continuous operation. At that time, the num-
ber of illuminated LEDs changes from two to one,
indicating the change. The LO-level setting will turn OFF
automatically after approximately 30 minutes.
NOTE:
When a heat setting is selected, heat will be felt
within two to five minutes.
WARNING!
• Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care

When the optional cigar lighter heating element is used
in the power outlet, it heats when pushed in and pops out
automatically when ready for use.To preserve the heat-
ing element, do not hold the lighter in the heating
position. A second power outlet is located inside the center console
and is powered directly from the vehicle battery.
CAUTION!
•
Do not exceed the maximum power of 160 Watts (13
Amps) at 12 Volts. If the 160 Watt (13 Amp) power
rating is exceeded the fuse protecting the system
will need to be replaced.
• Power outlets are designed for accessory plugs
only. Do not insert any other object in the power
outlets as this will damage the outlet and blow the
fuse. Improper use of the power outlet can cause
damage not covered by your New Vehicle Limited
Warranty.

CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to the
heating elements. Labels can be peeled off after
soaking with warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the
window.
• Keep all objects a safe distance from the window.

Coolant Temperature Warning Light
Red TelltaleLight What It Means
Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the light turns on while driving,
safely pull over and stop the vehicle. If the A/C system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle. If the temperature reading does not return
to normal, turn the engine off immediately and call for service.
NOTE:
As the coolant temperature gauge approaches
H,this indicator will illuminate and a single
chime will sound. Further overheating will cause the temperature gauge to pass H.In this
case, a continuous chime will sound until the engine is allowed to cool or the 4 minutes du-
ration is expired, whichever come first.

for help.
CLIMATE CONTROLS
The air conditioning and heating system is designed to
make you comfortable in all types of weather.
Manual Heating And Air Conditioning
The Manual Temperature Controls consist of a series of
outer rotary dials and inner push knobs.
Blower Control
Rotate this control to regulate the
amount of air forced through the ven-
tilation system in any mode. The
blower speed increases as you move
the control to the right from the “O”
(OFF) position. There are seven blower
speeds.
Temperature Control
Rotate this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the dial left
into the blue area of the scale indicates
cooler temperatures, while rotating
right into the red area indicates
warmer temperatures.

•Extended use of recirculation may cause the windows
to fog. If the interior of the windows begins to fog,
push the Recirculation button to return to outside air.
Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper
visibility. For this reason, the system will not allow
recirculation to be selected while in defrost mode.
Attempting to use recirculation while in this mode will
cause the LED in the control button to blink and then
turn off.
• Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
mode by pushing the Recirculation button. However,
under certain conditions, while in Automatic mode,
the system is blowing air out the defrost vents. When
these conditions are present, and the Recirculation
button is pushed, the indicator will flash and then turn
off. This tells you that you are unable to go into
Recirculation mode at this time. If you would like the system to go into Recirculation mode, you must first
move the Mode knob to Panel, Bi-Level, Floor, or Mix
and then push the Recirculation button. This feature
reduces the possibility of window fogging.
Operating Tips
NOTE:
Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
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% OAT (Organic Additive Technology)
coolant that meets the requirements of FCA Material
Standard MS.90032 and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.

Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Anytime 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 the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem, increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
