System Maintenance
In Winter, the Climate Control system must be turned on at
least once a month for about 10 minutes.
Have the system inspected at an authorized dealer before the
Summer.Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning system.
When the air conditioning system is turned on, cool dehu-
midified air will flow through the outlets into the cabin. For
improved fuel economy, press the A/C button to turn off the
Floor Mode
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 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.
Front Defrost
Use Defrost mode with maximum temperature settings for best windshield and side window
defrosting and defogging. Turn the knob to the Front Defrost position. Air comes from the windshield
and side window demist outlets.

air conditioning and manually adjust the blower and airflow
mode settings. Also, make sure to select only Panel, Bi-Level
or Floor modes.
NOTE:
• For Manual Climate Controls, if the system is in Mix orDefrost Mode, the A/C can be turned off, but the A/C
system shall remain active to prevent fogging of the
windows.
• If fog or mist appears on the windshield or side glass, select Defrost mode, and increase blower speed if needed.
• 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 radi -
ator 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. The recirculation mode is not
allowed in Defrost mode to improve window clearing oper -
ation. 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.
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. Organic
Additive Technology (OAT) coolant (conforming to MS.90032)
is recommended. Refer to “Fluids And Lubricants” in “Tech
-
nical Specifications” for proper coolant selection.

Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration of
coolant is used. Refer to “Fluids And Lubricants” in “Tech -
nical Specifications” for proper coolant selection. Use of the
air recirculation mode during Winter months is not recom -
mended 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 on high. This will ensure adequate system
lubrication to minimize the possibility of compressor
damage when the system is started again. Window Fogging

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 Air Conditioning (A/C)
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 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.

Outside Air Intake
Make sure the air intake, located directly in front of the wind-
shield, 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.
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. Operating Tips Chart

Power Windows — If Equipped
Power Window Switch Panel
The control on the left front door panel has up-down
switches that give you fingertip control of all power
windows. There is a single opening and closing switch on the
front passenger door for passenger window control. If the vehicle is equipped with rear power windows, a single
opening and closing switch on the rear passenger doors for
passenger window control is provided.
NOTE:
The key off power delay feature will allow the power
windows to operate for up to three minutes after the ignition
is turned off. This feature is canceled when either front door
is opened.
The window opening mechanism is fitted with sensors that
can detect the presence of an obstacle while the window is
closing. When this happens, the system activates and the
movement of the glass is immediately reversed.
If the presence of an object is detected and the system is acti
-
vated, it may be necessary to perform the reset procedure by
fully opening the windows.

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.Window Bar Grates
Wind Buffeting
Wind buffeting can be described as the perception of pres -
sure on the ears or a helicopter-type sound in the ears. Your
vehicle may exhibit wind buffeting with the windows down
in certain open or partially open positions. This is a normal
occurrence and can be minimized. If the buffeting occurs
open the front windows together to minimize the buffeting.
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.
