present. Recirculation can be used in all modes
except for Defrost. Recirculation may be
unavailable if conditions exist that could create
fogging on the inside of the windshield. The A/C
can be deselected manually without disturbing
the mode control selection. Continuous use of
the Recirculation mode may make the inside air
stuffy and window fogging may occur. Extended
use of this mode is not recommended.
On systems with Manual Climate Controls, if
equipped, the Recirculation mode is not
allowed in Defrost mode to improve window
clearing operation. Recirculation is disabled
automatically if this mode is selected.
Attempting to use Recirculation while in this
mode causes the LED in the control button to
blink and then turns off.
Front Defrost Mode
Turn the mode control knob to the
Front Defrost position. Air comes from
the windshield and side window
demist outlets. When the defrost
button is selected, the blower level may
increase. Use Defrost mode with maximum
temperature settings for best windshield and
side window defrosting and defogging.
Rear Defrost Button
Push and release the Rear Defrost
Control button to turn on the rear
window defroster and the heated
outside mirrors (if equipped). The
Rear Defrost indicator illuminates when the rear
window defroster is ON. The rear window
defroster automatically turns OFF after
20 minutes.
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.

Temperature Control
Temperature Control regulates the temperature
of the air forced through the climate system.
The temperature increases as you
turn the temperature control knob
clockwise.
The temperature decreases as you
turn the temperature control knob
counterclockwise.
Blower Control
Blower Control regulates the amount
of air forced through the climate
system. There are seven blower
speeds available. The blower speed
increases as you turn the blower control knob
clockwise from the lowest blower setting. The
blower speed decreases as you turn the blower
control knob counterclockwise.
NOTE:
Depending on the configuration, your vehicle
may be equipped with four blower speeds.
Mode Control
Turn the mode control knob to change
the airflow distribution mode. The
airflow distribution mode can be
adjusted so air comes from the
instrument panel outlets, floor outlets, defrost
outlets and demist outlets.
Panel Mode
Air comes from the outlets in the
instrument panel. Each of these
outlets can be individually adjusted to
direct the flow of air. The air vanes of
the center outlets and outboard outlets can be
moved up and down or side to side to regulate
airflow direction. There is a shut off wheel
located below the air vents to shut off or adjust
the amount of airflow from these outlets.
Bi-Level Mode

Air comes from the instrument panel
outlets and floor outlets. A slight
amount of air is directed through
the defrost and side window
demister outlets.
NOTE:
Bi-Level mode is designed under comfort condi
-
tions to provide cooler air out of the panel
outlets and warmer air from the floor outlets.
Floor Mode
Air comes from the floor outlets.
A slight amount of air is directed
through the defrost and side window
demister outlets.
Mix Mode
Air is directed through the floor,
defrost, and side window demister
outlets. This setting works best in cold
or snowy conditions that require extra
heat to the windshield. This setting is good for
maintaining comfort while reducing moisture on
the windshield.
Climate Control OFF
To turn the Climate Controls off, turn
the blower control knob to the OFF (O)
position.

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. A solution of 50%
OAT (Organic Additive Technology) coolant that
meets the requirements of FCA Material
Standard MS.90032 and 50% water is
recommended Ú page 268.
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
Úpage 260.
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 leaves. Leaves collected in the air
intake may reduce airflow, 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.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized
dealer to service your cabin air filter, and to
have it replaced when needed.

CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the
vehicle's battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.) will
degrade the battery even more quickly.
Only use these intermittently and with
greater caution.
After the use of high power draw accesso -
ries, or long periods of the vehicle not being
started (with accessories still plugged in),
the vehicle must be driven a sufficient
length of time to allow the generator to
recharge the vehicle's battery.
