2006 DODGE DURANGO engine overheat

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 “H” 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

left/right turn signal is left on with the engine RPM
vehicle speed greater than 15 mph (24 km/h) for more
than one mile.
4. Low Fuel Warning Light
This indicator lights when the fuel gauge reads 1/8
of a tank or less.
5. High Beam Indicator
Indicates that headlights are on high beam.
6. Seat Belt Reminder Light
This light comes on for several seconds after the
ignition is turned ON as a reminder to “buckle
up.” This light will remain on as long as the seat
belt remains unbuckled. If this light flashes, it indicates a
fault in the airbag system. Have the system checked by
an authorized dealer.7. Fog Light Indicator — If Equipped
This light shows when the fog lights are ON.
8. Coolant Temperature Light
This light warns of an overheated engine condi-
tion. For a bulb check, this light will come on
momentarily when the ignition is turned On. If the
light turns on while driving, stop the vehicle, shift into N
(Neutral) and increase the engine speed for 2 to 3
minutes. If the temperature reading does not return to
normal, seek authorized service immediately.
184 INSTRUMENT PANEL AND CONTROLS

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 the vehicles speed.
10. Voltage Light
This light monitors the electrical system voltage.
The light should turn on momentarily as the
engine is started. If the light stays on or turns on while
driving, it indicates a problem with the charging system.
Immediate service should be obtained.
11. Liftgate Open
The Gate Open light will illuminate when the liftgate is
not properly closed.
12. Security Light
This light will flash rapidly for approximately 15 seconds
when the vehicle theft alarm is arming. The light will
flash at a slower speed continuously after the alarm is set.
The security light will also come on for about three
seconds when the ignition is first turned on.

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.

ROCKING THE VEHICLE
If vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between FIRST and REVERSE,
while applying slight pressure to the accelerator.
The least amount of accelerator pedal pressure to main-
tain the rocking motion without spinning the wheels or
racing the engine is most effective. Allow the engine to
idle with the transmission selector in NEUTRAL for at
least one minute after every five rocking-motion cycles.
This will minimize overheating and reduce the risk of
transmission failure during prolonged efforts to free a
stuck vehicle.

264 STARTING AND OPERATING

CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system.
WARNING!
•Never allow any lit smoking materials near the
vehicles while removing the cap or filling the
tank.
•Never add fuel to the vehicle when the engine is
running.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s performance:
•The use of leaded gas is prohibited by Federal law. Using
leaded gasoline can impair engine performance, damage the
emission control system.
•An out-of-tune engine, or certain fuel or ignition malfunc-
tions, can cause the catalytic converter to overheat. If you
notice a pungent burning odor or some light smoke, your
engine may be out of tune or malfunctioning and may
require immediate service. Contact your dealer for service
assistance.
•When pulling a heavy load or driving a fully loaded vehicle
when the humidity is low and the temperature is high, use a
premium unleaded fuel to help prevent spark knock. If spark
knock persists, lighten the load, or engine piston damage
may result.
•The use of fuel additives which are now being sold as octane
enhancers is not recommended. Many of these products contain
high concentrations of methanol. Fuel system damage or vehicle
performance problems resulting from the use of such fuels or
additives is not the responsibility of the manufacturer.

CATALYTIC CONVERTER
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device. Under normal
operating conditions, the catalytic converter will not
require maintenance. However, you must keep the en-
gine maintained to assure proper operation and prevent
possible damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
As with any vehicle, do not park or operate this vehicle in
areas where combustible materials such as grass or leaves
can come in contact with a hot exhaust system.
A scorching odor may be detected if you continue to run
a malfunctioning engine. The odor may indicate severe
and abnormal catalyst overheating. If this occurs, the

NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Tow/Haul (If Equipped)
To reduce potential for automatic transmission overheat-
ing, turn the “TOW HAUL OD/OFF” feature ON when
driving in hilly areas or shift the transmission to Drive
position 2 on more severe grades.
Towing Tips — Electronic Speed Control (If
Equipped)

Don’t 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.
Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in neutral and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
