²Panel
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to
direct airflow.
NOTE:The center instrument panel outlets can be
aimed so that they are directed toward the rear seat
passengers for maximum airflow to the rear.
²Bi-Level
Air is directed through the panel and floor out-
lets.
NOTE:For all settings except full cold or full hot, there
is a difference in temperature between the upper and
lower outlets. The warmer air flows to the floor outlets.
This feature gives improved comfort during sunny but
cool conditions.
²Floor
Air is directed through the floor outlets with a
small amount flowing through the defrost and
side window demist outlets.
²Mix
Air is directed through the floor, defrost, and
side window demist 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.
²Defrost
Air is directed through the windshield and side
window demist outlets. Use this mode with
maximum blower and temperature settings for best
windshield and side window defrosting.
262 INSTRUMENT PANEL AND CONTROLS

NOTE:The air conditioning compressor operates in Mix
and Defrost, or a blend of these modes, even if the Air
Conditioning Snowflake button is not pressed. This de-
humidifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
²Recirculation Control
Use this button to block the flow of outside
air from coming into the passenger compart-
ment. A light will illuminate when the sys-
tem is in recirculation mode. Only use the
recirculation mode as a temporary means to block out
any outside odors, smoke, or dust, and to cool the
interior rapidly upon initial start up in very hot or
humid weather.
NOTE:
²Continuous use of the recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
²The use of the recirculation mode in cold or damp
weather will cause windows to fog on the inside,
because of moisture build-up inside the vehicle. Select
the Outside Air position for maximum defogging.
²The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or panel / floor.
²The A/C can be deselected manually without disturb-
ing the mode control selection.
Air Conditioning Control
Use this button to engage the Air Conditioning. A
light will illuminate when the Air Conditioning
System is engaged
NOTE:The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.

²Air Conditioner Control
Press this button to turn on the air conditioning
during manual operation only. When the air
conditioning is turned on, cool dehumidified
air will flow through the outlets selected with the
Mode control dial. Press this button a second time to
turn off the air conditioning. An LED in the button
illuminates when manual compressor operation is
selected.
²Recirculation Control
The system will automatically control recir-
culation. However, pressing the Recircula-
tion Control button will temporarily put the
system in recirculation mode (ten minutes).
This can be used when outside conditions such as
smoke, odors, dust, or high humidity are present.
Activating recirculation will cause the LED in the
control button to illuminate. After ten minutes, the
system will return to normal AUTO mode function
and the LED will turn off.NOTE:
²When the ignition switch is turned to the LOCK
position, the recirculation feature will be cancelled.
²In cold weather, use of the Recirculation mode may
lead to excessive window fogging. The Recirculation
mode is not allowed in the floor, defrost, or defrost/
floor mode in order to improve window clearing.
Recirculation will be disabled automatically if these
modes are selected.
²Extended 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 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 floor, defrost, or
defrost/floor mode. Attempting to use the recircula-
tion while in these modes will cause the LED in the
control button to blink and then turn off.

²Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
Mode by pressing 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 pressed, 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, Panel/Floor and then
press 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 in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to ªMaintenance Proceduresº in Section 7 of this manual
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 condi-
tioning system at idle for about five minutes in the fresh
air and high blower settings. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
270 INSTRUMENT PANEL AND CONTROLS

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.
Side Window Demisters
A side window demister outlet is located at each end of
the instrument panel. These non-adjustable outlets direct
air toward the side windows when the system is in the
FLOOR, MIX, or DEFROST mode. The air is directed at
the area of the windows through which you view the
outside mirrors.
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 Ð If Equipped
The A/C Air Filter will reduce, but not eliminate, diesel
and agricultural smells. The filter acts on air coming from
outside the vehicle and recirculated air within the pas-
senger compartment. Refer to ªMaintenance Proceduresº
in Section 7 of this manual for A/C Air Filter service
information or see your authorized dealer for service.
Refer to the ªMaintenance Schedulesº in Section 8 of this
manual for filter service intervals.

WARNING!
²Always apply the parking brake fully when leav-
ing your vehicle or it may roll and cause damage or
injury. Also, be certain to leave an automatic
transmission in ªPº (Park) or a manual transmis-
sion in ªRº (Reverse) or 1st gear. Failure to do so
may allow the vehicle to roll and cause damage or
injury.
²Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be injured. Don't leave the keys in the
ignition. A child could operate power windows,
other controls, or move the vehicle.
²Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
problems due to excessive heating of the rear
brakes.When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should always be applied whenever
the driver is not in the vehicle.
ANTI-LOCK BRAKE SYSTEM
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
310 STARTING AND OPERATING

The matching full size spare wheel and tire assembly (if
equipped) has a tire pressure monitoring sensor. The
matching full size spare can be used in place of any of the
four road tires. The TPMS will only monitor the pressure
in the full size spare when it is used in place of a road tire.
Otherwise, a spare with a pressure below the low-
pressure limit will not cause the Tire Pressure Monitoring
Telltale Light to illuminate or the chime to sound.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or
more of the four active road tires. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle's recommended cold placard pressure
value. Once the system receives the updated tire pres-
sures, the system will automatically update and the Tire
Pressure Monitoring Telltale Light will turn off. Thevehicle may need to be driven for up to 10 minutes above
15 mph (25 km/h) in order for the TPMS to receive this
information.
Check TPMS Warning
When a system fault is detected, the Tire Pressure Moni-
toring Telltale Light will flash on and off for 75 seconds
and then remain on solid. The system fault will also
sound a chime. If the ignition key is cycled, this sequence
will repeat, providing the system fault still exists. The
Tire Pressure Monitoring Telltale Light will turn off when
the fault condition no longer exists. A system fault can
occur due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
