•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 accumulation of dirt or
insects. Clean with a gentle water spray from the front of
the radiator and through the condenser.
Recirculation
In cold weather, use of Recirculation mode may lead to
excessive window fogging. The Recirculation feature may
be unavailable 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.
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.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
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) cool-
ant that meets the requirements of FCA Material Standard
MS.90032 and 50% water is recommended. Refer to “Fluids
And Lubricants” in “Technical Specifications” 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
Any time 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 compressor dam-
age when the system is started again.

Window Fogging
Interior fogging on the windshield can be quickly removed 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 window 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.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
• Use care when washing the inside of the rear win-
dow. 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 heat-
ing elements. Labels can be peeled off after soaking
with warm water.
(Continued)
CAUTION! (Continued)
•Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the win-
dow.
• Keep all objects a safe distance from the window.
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.
A/C Air Filter
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be totally
filtered out. Refer to “Dealer Service” in “Servicing and
Maintenance” for filter replacement instructions.

WARNING!
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
• Do not leave the key fob in or near the vehicle or in
a location accessible to children. A child could oper-
ate power windows, other controls, or move the
vehicle.

The window switches may be equipped with an Auto-
Down feature. Push the window switch for half a second,
release, and the window will go down automatically.
To stop the window from going all the way down during
the auto-down operation, pull up or push down on the
switch briefly.
To open the window part way, lift the window switch to
the detent for less than half a second and release it to stop
the window. NOTE:
The power window switches remain active for up
to three minutes after the ignition switch has been turned
OFF. Opening either of the vehicle’s front doors will cancel
this feature.
Window Bar Grates — If Equipped
This vehicle may be equipped with metal grates over the
side door windows. This feature is a part of the vehicle’s
safety system, and is designed to protect you and your
passengers in the event of an accident.

WARNING!
The metal grates over the sliding door windows are
designed to protect you in the event of an accident.
Modification or removal of the grates could lead to
serious injury or death.
Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the ears.
Your vehicle may exhibit wind buffeting with the windows
down, or the sunroof (if equipped) in certain open or
partially open positions. This is a normal occurrence and
can be minimized. If the buffeting occurs with the rear
windows open, open the front and rear windows together
to minimize the buffeting. If the buffeting occurs with the
sunroof open, adjust the sunroof opening to minimize the
buffeting or open any window.
HOOD
Opening
To open the hood, two latches must be released.1. Open the driver ’s door to gain access to the hood release
lever. Pull the hood release lever located on the side of
the instrument panel.

WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
• Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
(Continued)
CAUTION! (Continued)
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently 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 accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle’s battery.
