2008 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 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 en-
gine 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
1/16 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 ªbuckle
up.º 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. 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.
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.
194 INSTRUMENT PANEL AND CONTROLS

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.
8. Speedometer
Shows the vehicles speed.
9. 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.10. 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.
11. ABS Warning Light
This light monitors the Anti-Lock Brake System
which is described elsewhere in this manual.
This light will come on when the ignition key is
turned to the ON position and may stay on for
approximately 3 seconds. If this light remains on or
comes on during driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that
service is required. See your authorized dealer immedi-
ately. With the ABS malfunctioning, the BAS and ESP are
also switched off. Both malfunction indicator lights illu-
minate with the engine running. If the charging voltage
falls below 10 volts, the malfunction indicator light

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
Be sure to turn off the engine and remove the key
from the ignition switch if you want to rest or sleep
in your car. Accidents can be caused by inadvertently
moving the gear selection lever or by pressing the
accelerator pedal. This may cause excessive heat in
the exhaust system, resulting in overheating and
vehicle fire which may cause serious or fatal injuries.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Automatic Transmission
Start the engine with the selector lever in NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting
Normal Starting of either a warm or cold engine is
obtained without pumping or depressing the accelerator
pedal.
STARTING AND OPERATING 273

The transmission will downshift from Overdrive to Drive
if the accelerator pedal is fully depressed at vehicle
speeds above approximately 35 mph (56 km/h).
When To Use ªTOW/HAULº Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the ªTOW/HAULº button. This will improveperformance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in ªTOW/HAULº mode, 5th gear (if
equipped) is disabled and 2-3 and 3-4 shift patterns are
modified. Shifts into Overdrive (4th gear) are allowed
during steady cruise (for improved fuel economy) and
automatic closed-throttle downshifts to 3rd gear (for
improved braking) will occur during steady braking.
The ªTOW/HAULº light will illuminate in the instru-
ment cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the ªTOW/HAULº mode is desired,
the button must be pressed each time the engine is
started.
Torque Converter Clutch
A feature designed to improve fuel economy is included
in all automatic transmissions. A clutch within the torque
converter engages automatically at a calibrated speed at

Materials Added To Fuel
All gasolines sold in the United States are required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's performance:
²The use of leaded gas is prohibited by Federal law. Using
leaded gasoline can impair engine performance, damage the
emission control system.
²An 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.
²When 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.
²The 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.
STARTING AND OPERATING 335

If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Towing Tips Ð Automatic Transmission
The ªDº range can be selected when towing. However, if
frequent shifting occurs while in this range, the ªTOW
HAULº feature should be selected.
NOTE:Using the ªTOW HAULº feature while operat-
ing the vehicle under heavy operating conditions will
improve performance and extend transmission life by
reducing excessive shifting and heat build up. This action
will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See the Maintenance
Schedule in section 8 of this manual for transmission
fluid change intervals.NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips Ð Tow/Haul (If Equipped)
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.
Towing Tips Ð Electronic Speed Control (If
Equipped)
þ
Don't use in hilly terrain or with heavy loads.
þWhen 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.
þUse speed control in flat terrain and with light loads to
maximize fuel efficiency.
358 STARTING AND OPERATING

WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
FREEING A STUCK 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.
EMERGENCY TOW HOOKS Ð IF EQUIPPED
Your vehicle may be equipped with emergency tow
hooks.
NOTE:For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of
damage to the vehicle.
