INSTRUMENT CLUSTER DESCRIPTION
1. Fuel Gage
The fuel gauge shows level of fuel in tank when
ignition switch is in the ON position.
2. Temperature Gage
The temperature gage indicates engine coolant
temperature. Any reading within the normal
range indicates that the cooling system is operat-
ing satisfactorily. The gage needle in V6 and V8 engines
will likely indicate a high temperature when driving in
hot weather, up mountain grades, in heavy traffic, or
when towing a trailer. If the needle rises to the ªHº mark,
stop the vehicle, shift into N (Neutral) increase engine
speed for 2-3 minutes. If the temperature reading does
not return to normal, seek authorized service immedi-
ately.
CAUTION!
Do not leave your vehicle unattended with the
engine running as you would not be able to react to
the temperature indicator if the engine overheats.
The gage pointer will remain near its last reading when
the engine is turned off. It will return to a true reading
when the engine is restarted.
3. Turn Signal Indicators
When a turn signal is activated, a right-pointing or
left-pointing arrow lights up and flashes to indicate the
direction of the turn. These indicators also indicate
proper operation of the front and rear turn signal lights.
If either indicator flashes at a faster rate than normal,
check for a defective bulb. If either indicator fails to light
up when the lever is moved, check for a defective fuse or
turn signal LED. A single chime is activated when the

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature light is on,
safely pull over and stop the vehicle. Idle the vehicle
in neutral with the air conditioner turned off until
the light turns off. If the if the light remains on, turn
the engine off immediately, and call for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.
9. Speedometer
Shows vehicle speed in miles per hour and kilometers
per hour.
10. Voltage Light
This light monitors the electrical system voltage.
The light should turn on momentarily as the

Front Mode Control
The mode control allows you to
choose from several patterns of air
distribution.
NOTE:To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots and give an even blend of both
modes.
Recirculation Mode (Panel or Bi-Level)
Select either the Panel or Bi-Level
mode positions when the outside air
contains smoke, odors, high humidity,
or if rapid cooling of the interior is
desired. This feature allows for recir-
culation of interior air only. Air flows
through the panel outlets or panel and
floor outlets in these modes.
Panel
Outside air flows through the outlets located in the
instrument panel. These outlets can be adjusted to
direct the airflow.
Bi-Level
Air flows through the outlets located in the instru-
ment panel and those located on the floor.

Manual Control (ATC)
You also may choose to customize your comfort by
selecting the fan speed and mode manually. Pressing the
fan speed button or any mode button places the system
into manual operation.
While in manual operation there are six fan speeds
available and the choice of any mode. The airflow
temperature is adjusted automatically to maintain the
desired comfort level. You can adjust the temperature by
pressing the + or ± TEMP rocker switch.
FAN Control
Use this button to regulate the amount of air deliv-
ered through the system in any mode you select.
Press the + or ± side of the button to increase or decrease
fan speed.
Air Conditioning Operation
Press this button to turn on the air conditioning
compressor. A snow flake symbol in the displayshows that the compressor is on. Compressor operation is
automatic when you press the AUTO button and no
snowflake is shown.
The compressor can operate at any temperature above
32ÉF (0ÉC).
NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes in
engine speed or power may be noticed when the com-
pressor is on. This is a normal occurrence since the
compressor will cycle on and off to maintain comfort and
improve fuel economy.
Recirculate Button
Press this button to recirculate the air inside the
vehicle. Outside air is prevented from entering
the vehicle. Use this mode to temporarily block
out any outside odors, smoke, dust or when
rapid cooling of the interior is required.

and blower speed to maintain comfort. Interior fogging
on the windshield can be quickly removed by selecting
the defrost mode.
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.When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear.
When stopped in heavy traffic, it may be necessary to
shift into NEUTRAL and press the accelerator slightly for
fast idle operation.
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 obstruc-
tions.

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.
Cooling System TipsÐTrailer Towing
To reduce potential for engine and transmission over-
heating, take the following actions:
²City Driving
When stopped for short periods of time, put transmission
in neutral and increase engine idle speed.
4 - Pin Connector
7 - Pin Connector
260 STARTING AND OPERATING

²Highway Driving
Reduce speed.
²Air Conditioning
Turn off temporarily.
²See Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
To reduce potential for automatic transmission overheat-
ing, turn the ªTOW/HAULº feature on when driving in
hilly areas or shift the transmission to Drive position 2 on
more severe grades. Move the shift lever to the next
lower position to eliminate excessive transmission shift-
ing. This action will also reduce the possibility of trans-
mission overheating and provide better engine braking.
SNOWPLOW
Dodge Durango Models
NOTE:Do not use Dodge Durango Models for snow-
plow applications.
WARNING!
Snowplows, winches, and other aftermarket equip-
ment should not be added to the front end or your
vehicle. The airbag crash sensors may be affected by
the change in the front end structure. The airbags
could deploy unexpectedly or could fail to deploy
during a collision resulting in serious injury or
death.

freezing the fluid on the cold windshield. MopartAll
Weather Windshield Washer Solution used with water as
directed on the container, aids cleaning action, reduces
freezing point to avoid line clogging, and is not harmful
to paint or trim.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, fol-
low the preceding safety tips.
Cooling System
Inspection
Coolant protection checks should be made at every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant. Check face of radiator for any accumulation of
