Temperature Control
Rotate this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the dial left
into the blue area of the scale indicates
cooler temperatures, while rotating
right into the red area indicates
warmer temperatures.
NOTE: If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser located in front of the radiator for an accumula-
tion 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.
Mode Control (Air Direction)
Rotate this control to choose from sev-
eral patterns of air distribution. You
can select either a primary mode as
identified by the symbols on the con-
trol, or a blend of two of these modes.
The closer the setting is to a particular
symbol, the more air distribution you
receive from that mode.
Panel Air is directed through the outlets in the instrument
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.
Bi-Level Air is directed through the panel and floor outlets.

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.
Blower Control
For full automatic operation or for
automatic blower operation, turn the
knob to the AUTO position. In manual
mode there are seven blower speeds
that can be individual selected. In off
position the blower will shut off.
Manual Operation
This system offers a full complement of manual override
features, which consist of Blower Preferred Automatic,
Mode Preferred Automatic, or Blower and Mode Pre-
ferred Automatic. This means the operator can override
the blower, the mode, or both. There is a manual blower
range for times when the AUTO setting is not desired.
The blower can be set to any fixed blower speed by
rotating the Blower Control knob (on the left).
NOTE:Please read the Automatic Temperature Control
Operation Chart that follows for details.

soft bottoms the vehicle will sink in, effectively increas-
ing the water level on the vehicle. Be sure to consider this
when determining the depth and the ability to safely
cross.
Crossing Puddles, Pools, Flooded Areas Or Other
Standing Water
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water
holes are where you want to hook up tow straps prior to
entering. This makes for a faster, cleaner and easier
vehicle recovery. If you are able to determine you can
safely cross, than proceed using the low and slow
method.
CAUTION!
Muddy waters can reduce the cooling system effec-
tiveness by depositing debris onto the radiator.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you
can get any problems taken care of right away and have
your vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
•Inspect the radiator for mud and debris and clean as
required.
310 STARTING AND OPERATING

•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
•Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
•After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
•If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.

STARTING AND OPERATING 311

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 ac-
tion.
•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.
380 WHAT TO DO IN EMERGENCIES

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the pointer rises to the H (red) mark,
the instrument cluster will sound a chime. When
safe, pull over and stop the vehicle with the engine at
idle. Turn off the air conditioning and wait until the
pointer drops back into the normal range. If the
pointer remains on the H (red) mark for more than a
minute, turn the engine off immediately and call for
service.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
AUTOMATIC TRANSMISSION OVERHEATING
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 in-
dicator light will come on, and the vehicle will
slow slightly until the automatic transmission
cools down enough to allow a return to the
requested speed. If the high speed is maintained, the
overheating may reoccur, as before, in a cyclic fashion.6
WHAT TO DO IN EMERGENCIES 381

CAUTION!
Do not use a portable battery booster pack or any
other booster source with a system voltage greater
than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
WARNING!
Do not attempt jump-starting if the battery is frozen.
It could rupture or explode and cause personal injury.
Preparations For Jump-Start
The battery in your vehicle is located in the front of the
engine compartment below the air intake duct. To access
the battery remove the air intake duct by turning the two
finger screws, located on the radiator support.

WHAT TO DO IN EMERGENCIES 389

WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be injured by
moving fan blades.
•Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.
•Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift the automatic transmission
into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories.

hood latching components to ensure proper function.
When performing other underhood services, the hood
latch, release mechanism and safety catch should be
cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR
Lock Cylinder Lubricant or equivalent directly into the
lock cylinder.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild, nonabrasive cleaner or use the washer solvent. This
will remove accumulations of salt, waxes or road film
and help reduce streaking and smearing.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt from a dry windshield. Avoid using the wiper blades to
remove frost or ice from the windshield. Make sure that
they are not frozen to the glass before turning them on to
avoid damaging the blade. Keep the blade rubber out of
contact with petroleum products such as engine oil,
gasoline, etc.
NOTE:
Life expectancy of wiper blades varies depend-
ing on geographical area and frequency of use. Poor
performance of blades may be present with chattering,
marks, water lines or wet spots. If any of these conditions
are present, clean the wiper blades or replace as
necessary.
Adding Washer Fluid
The washer fluid reservoir is located in the engine
compartment, and the fluid level should be checked at
regular intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
412 MAINTAINING YOUR VEHICLE

To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
Cooling System
WARNING!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position.
•You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, do not open
the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator is hot.
