WARNING!
Driving a vehicle with the head restraints removed or
improperly adjusted could cause serious injury or
death in the event of a collision. The head restraints
should always be checked prior to operating the
vehicle and never adjusted while the vehicle is in
motion. Always adjust the head restraints when the
vehicle is in PARK.
Front Heated Seats — If Equipped
The controls for each heater are located near the bottom
center of the instrument panel (below the heater/air
conditioning controls).
After turning the ignition ON, you can choose from High,
Low or Off heat settings. Amber indicator lights in each
switch indicate the level of heat in use. Two indicator
lights will illuminate for High, one for Low and none for
Off.Press the switch once to select High-level heat-
ing. Press the switch a second time to select
Low-level heating. Press the switch a third time
to shut the heating elements Off.
When High-level heating is selected, the heaters provide
a boosted heat level during the first four minutes of
operation after heating is activated. The heat output then
drops to the normal High-level. If High-level heating is
selected, the system will automatically switch to the
Low-level after approximately 30 minutes of continuous
operation. At that time, the number of illuminated LEDs
changes from two to one, indicating the change. Opera-
tion on the Low-level setting also turns Off automatically
after approximately 30 minutes.
NOTE: Once a heat setting is selected, heat will be felt
within two to five minutes.

6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.
NOTE:If you experience difficulty in playing a particu-
lar disc, it may be damaged (i.e., scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have protection encoding. Try a known
good disc before considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being on in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
Manual Heating and Air Conditioning System — If
Equipped
The controls for the heating and air conditioning system
in this vehicle consist of a series of rotary knobs. These
comfort controls can be set to obtain desired interior
conditions.

RecirculationThe recirculation feature can be selected with
the mode control knob. You may choose be-
tween Bi-Level Recirculation and Panel Recir-
culation air outlets while in this mode. Nor-
mally, air enters from outside the vehicle. However, when
in Recirculation mode air inside the vehicle is re-used.
Use this mode to rapidly cool the inside of the vehicle.
The Recirculation mode can also be used to temporarily
block out outside odors, smoke, and dust.
Air Conditioning To turn on the Air Conditioning, set the fan control
at any speed and press the snowflake button
located on the control panel. Conditioned air will
be directed through the outlets selected by the mode
control. A light in the snowflake button shows that the air
conditioning is on. Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is a
normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
Automatic Temperature Control (ATC) — If
Equipped
The Automatic Temperature Control (ATC) system auto-
matically maintains the interior comfort level desired by
the driver and passenger.
226 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:The numbers on the temperature dial represent
a comfort setting when the Mode knob is set to AUTO,
and not the actual air temperature. Turn the mode control (on the right) knob to AUTO, and
place the blower control (on the left) to either LO AUTO
or HI AUTO. The LO AUTO position should be used for
front seat occupants only. The HI AUTO position should
be used when more airflow is desired, or when rear seat
occupants are present. Dial in the comfort setting you
would like the system to maintain by rotating the driver’s
or passenger’s control knob. Once the comfort level is
selected, the system will maintain that level automati-
cally using the heating system. Should the desired com-
fort level require air conditioning, the system will auto-
matically make the adjustment.
Automatic Temperature Controls (ATC)
4
UNDERSTANDING YOUR INSTRUMENT PANEL 227

NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation. How-
ever, if the driver and/or passenger temperature knobs
are set to the full hot or full cold positions, the air
temperature out of the ducts will be full hot or full cold
respectively. With the temperature setting in these posi-
tions, the system does not attempt automatic comfort
control.
Air Conditioning The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause the LED to flash three times and remain off.
This indicates that the system is in AUTO and requesting
the air conditioning is not necessary. Recirculation
The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in Recirculation mode.
This can be used when outside conditions such
as smoke, odors, dust, or high humidity are present. This
will cause the LED to illuminate.
NOTE:
•The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor’s location.
Mud on the windshield may also cause poor operation
of this system.

Bi-LevelAir flows both through the outlets located in the
instrument panel and those located on the floor. Air
flows through the registers in the back of the center
console, and under the front seats to the rear seat
passengers. These registers can be closed to block airflow.
The center console outlets deliver conditioned air while
the floor outlets deliver heated air.
Panel Air flows through the outlets located in the instru-
ment panel. Air flows through the registers in the
back of the center console to the rear seat passengers.
These registers can be closed to block airflow.
Air Conditioning Press this button to turn on and off the air condi-
tioning during manual operation only. Condi-
tioned outside air is then directed through the outlets selected on the mode control dial. The button
includes an LED that illuminates when manual operation
is selected.
NOTE:
To manually control the air conditioning, the
mode selector must be moved out of the AUTO position.
Recirculation This button can be used to block out smoke,
odors, dust, high humidity, or if rapid cooling
is desired. The Recirculation mode should only
be used temporarily. The button includes an
LED that illuminates, which indicates that the Recircula-
tion mode is active. You may use this feature separately.
NOTE: Extended use of recirculation may cause the
windows to fog. If the interior of the windows begins to
fog, press the Recirculation button to return to outside
air. Some temperature/humidity conditions will cause
captured interior air to condense on windows and ham-
per visibility. For this reason, the system will not allow

Rear Temperature Control
The center knob on the Rear Control Panel allows the
third row seat occupants to have control of the rear
temperature as follows:
•When the temperature knob is in the cold (Blue)
position, cold air will be delivered from the outlets. As
the temperature knob is turned towards the hot (Red)
position, the air will get warmer.
Rear Mode Control
FloorAir flows through the floor outlet located on the
right side of the rear floor into the rear seating area.
Bi-Level Air flows through both the outlets located in the
rear quarter trim panels, and the one located on the
floor. The rear quarter trim panel outlets can be closed to
block airflow. Panel
Air flows through the outlets located in the rear
quarter trim panels. These registers can be closed to
block airflow.
Operating Tips
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases,
turning on the air conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder, it may be necessary to
direct air onto the windshield. Adjust the temperature
control and blower speed to maintain comfort. Higher
blower speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by selecting the
defrost mode.4
UNDERSTANDING YOUR INSTRUMENT PANEL 235

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant, during summer, to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration is recommended. Refer to Fluids, Lubri-
cants, and Genuine Parts in Section 7 for the proper
coolant type.
When using the air conditioner in extremely heavy
traffic, in hot weather, especially when towing a trailer,
additional engine cooling may be required. If this situa-
tion is encountered, operate the transmission in a lower
gear to increase engine RPM, coolant flow and fan speed.
When stopped in heavy traffic, it may be necessary toshift into NEUTRAL and press the accelerator slightly for
fast idle operation to increase coolant flow and fan speed.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other
obstructions.
Vacation Storage
Anytime 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 com-
pressor damage when the system is started again.
236 UNDERSTANDING YOUR INSTRUMENT PANEL

Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
SNOW PLOW
Snow plows, winches, and other aftermarket equipment
should notbe added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in the
front end structure. The airbags could deploy unexpect-
edly or could fail to deploy during a collision.
WARNING!
Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing – Two-Wheel Drive Models
Recreational towing is allowed ONLY if the driveshaft
is removed. Towing with the rear wheels on the ground
while the driveshaft is connected can result in severe
transmission damage.
