Manual Heating And Air Conditioning
The Manual Temperature Controls consist of a series of
outer rotary dials and inner push knobs.
Blower Control
Rotate this control to regulate the
amount of air forced through the ven-
tilation system in any mode. The
blower speed increases as you move
the control to the right from the “O”
(OFF) position. There are seven blower
speeds.
NOTE: For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the blower control is left in the “O” (Off)
position.

NOTE:The AUTO position performs best for front seat
occupants only.
2. Dial in the temperature you would
like the system to maintain by rotating
the Temperature Control knob. Once
the comfort level is selected, the sys-
tem will maintain that level automati-
cally using the heating system. Should
the desired comfort level require air
conditioning, the system will automatically make the
adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the “O” (OFF) position on the blower control stops the
system completely and closes the outside air intake.
The recommended setting for maximum comfort for the
average person is 72°F (22°C); however, this may vary. NOTE:
•The temperature setting can be adjusted at anytime
without affecting automatic operation.
•Pressing the Air Conditioning Control button while in
AUTO mode will cause the LED in the control button
to flash three times and then turn off. This indicates
that the system is in AUTO mode and requesting the
air conditioning is not necessary.
•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 behind
the radiator and through the condenser. Fabric front
fascia protectors may reduce airflow to the condenser,
reducing air conditioning performance.

•Most 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, Bi-Level 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 solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” 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
conditioning system at idle for about five minutes in the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

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 — If Equipped
The A/C Filter prevents most dust and pollen from
entering the cabin. The filter acts on air coming from
outside the vehicle and recirculated air within the pas-
senger compartment. Refer to “Maintenance Procedures”
in “Maintaining Your Vehicle” for A/C Air Filter service
information or see your authorized dealer for service.
Refer to “Maintenance Schedules” for filter service
intervals.

CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can result
in severe transmission damage. Refer to “Recre-
ational Towing” in “Starting And Operating” and
“Towing A Disabled Vehicle” in What To Do In
Emergencies” for further information.
DRIVE
This range should be used for most city and highway
driving. It provides the best fuel economy. The DRIVE
position provides optimum driving characteristics under
all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the AutoStickmode (if
equipped) to select a lower gear. Under these conditions, using a lower gear will improve performance and extend
transmission life by reducing excessive shifting and heat
buildup.
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transmission oil
may become too hot. If this happens, the transmission
overheat indicator light will come on, and the vehicle will
slow slightly until the transmission cools down enough
to allow a return to the requested speed. This is done to
prevent transmission damage due to overheating. If the
high speed is maintained, the overheating may reoccur,
as before, in a cyclic fashion.
LOW – IF EQUIPPED
This range should be used for engine braking when
descending very steep grades. In this range, the trans-
mission will downshift for maximum engine braking,
and upshifts will occur only to prevent engine overspeed.

STARTING AND OPERATING 305

General Information
•
If a ratio other than first is selected and the vehicle is
brought to a stop, the transmission control logic will
automatically select the first gear ratio.
•If a low range is selected and the engine accelerates to
the rev limit, the transmission will automatically select
the next higher ratio.
•If a downshift would cause the engine to overspeed,
that shift will not occur until it is safe for the engine.
•If the system detects powertrain overheating, the
transmission will revert to the automatic shift mode
and remain in that mode until the powertrain cools off.
•If the system detects a problem, it will disable the
AutoStickmode and the transmission will return to
the automatic mode until the problem is corrected.
FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
This feature provides full time, on-demand, four–wheel
drive (4WD).
Where one or more wheels have wheel spin or if addi-
tional traction is needed in sand, deep snow, or loose

WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:
Safety
WARNING!
•Improperly inflated tires are dangerous and can
cause collisions.
•Under-inflation increases tire flexing and can re-
sult in over-heating and tire failure.
•Over-inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can
cause damage that result in tire failure.
•Over-inflated or under-inflated tires can affect
vehicle handling and can fail suddenly, resulting
in loss of vehicle control.
•Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.(Continued)
336 STARTING AND OPERATING

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Manual Transmission – If Equipped
If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission – If Equipped
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.
Electronic Speed Control – If Equipped

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce the potential for engine and transmission
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL but do not increase engine idle
speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel, below the radio.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
•On the highways — slow down.
•In city traffic — while stopped, place the transmission
in NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition:
•If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
•You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the engine cooling system.
