2009 DODGE DURANGO engine

release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the normal starting procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15 sec-
onds before trying again.
After Starting
The idle speed is automatically controlled on fuel injected
engines and will decrease as the engine warms up.
ENGINE BLOCK HEATER – IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 volt AC electrical outlet with a
grounded, three wire extension cord.Use the heater when temperatures below 0°F (-18°C) are
expected to last for several days.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.
The engine block heater cord is located:
•3.7L/4.7L Engine — at the front of the engine com-
partment near the radiator cap.
•5.7L Engine — on the left side of the engine compart-
ment and rearward of the power distribution center.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could cause
electrocution.

AUTOMATIC TRANSMISSION
NOTE:Under extreme cold temperatures (-6°F (-21°C)
and when in DRIVE, transmission operation may be
briefly limited to only 2nd gear operation. Normal op-
eration will resume once the transmission temperature
has risen to a suitable level.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
(Continued)
CAUTION! (Continued)
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on the brake pedal,
the vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and when your foot is
firmly on the brake pedal.
292 STARTING AND OPERATING

Brake/Transmission Interlock System
This system prevents you from moving the shift lever out
of PARK and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress thebrake
pedal first,before moving the shift lever out of PARK.
Gear Ranges
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold. If
there is a need to restart the engine, be sure to cycle the
key to the LOCK position before restarting. Transmission
gear engagement may be delayed after restarting the
engine if the key is not cycled to the LOCK position first.
PARK
This gear supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Applythe parking brake when leaving the vehicle in this range.
Always apply the parking brake first, then place the shift
lever into the PARK position.
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly forward
or in reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and when
your right foot is firmly on the brake pedal.

REVERSE
Use this range only after the vehicle has come to a
complete stop.
NEUTRAL
Shift to NEUTRAL when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with the shift lever in NEUTRAL can result
in severe transmission damage. Refer to “Recreational
Towing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.
DRIVE
For most city and highway driving.2 (Second)
For driving slowly in heavy city traffic or on mountain
roads where more precise speed control is desirable. Use
it also when climbing long grades, and for engine brak-
ing when descending moderately steep grades. To pre-
vent excessive engine speed, do not exceed 45 mph
(72 km/h) in this range.
1 (First)
For driving up very steep hills and for engine braking at
low speeds (25 mph {40 km/h} or less) when going
downhill. To prevent excessive engine speed do not
exceed 25 mph (40 km/h) in this range.
294 STARTING AND OPERATING

Overdrive Operation
The automatic transmission contains an electronically
controlled fourth and fifth (if equipped) speed (OVER-
DRIVE). The transmission will automatically shift from
DRIVE to OVERDRIVE if the following conditions are
present:
•the transmission selector is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the TOW/HAUL switch has not been activated;
•transmission has reached normal operating
temperature.NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into OVER-
DRIVE and will automatically select the most desirable
gear for operation at this temperature. Normal operation
will resume when the transmission fluid temperature has
risen to a suitable level. Refer also to the Note under
torque converter clutch, later in this section.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “Transmission
Temperature Indicator Light” may illuminate and the
transmission may downshift out of OVERDRIVE until
the transmission cools down. After cooldown, the trans-
mission will resume normal operation.
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 TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in TOW/HAUL 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 “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the TOW/HAUL mode is desired,
the button must be pressed each time the engine is
started.
TOW/HAUL Button
296 STARTING AND OPERATING

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
light throttle. It engages at higher speeds under heavier
acceleration. This may result in a slightly different feeling
or response during normal operation in high gear. When
the vehicle speed drops below a calibrated speed, or
during acceleration, the clutch automatically and
smoothly disengages. The feature is operational in
OVERDRIVE and in DRIVE.
NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm (usu-
ally after 1-3 miles [1.6 - 4.8 km] of driving). Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into Overdrive when cold. This is
normal. Pressing the TOW/HAUL button, when thetransmission is sufficiently warm, will demonstrate
that the transmission is able to shift into, and out of,
Overdrive. For vehicles with 4.7L or 5.7L engines
(which have two Overdrive gears), the transmission
may not shift into 5th gear until the transmission fluid
and engine coolant are warm.
•If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds of shifting from
PARK into any other gear position.

roads. This feature provides the safety, security, and
convenience of operating in all-wheel drive at all times
regardless of road conditions.
When additional traction is required, the 4WD LOCK
and 4WD LOW positions can be used to lock the front
and rear driveshafts together, through the transfer case
inter-axle differential, and force the front and rear wheels
to rotate at the same speed. This is accomplished by
rotating the 4WD Control Switch to these positions. The
4WD LOCK and 4WD LOW positions are intended for
loose, slippery road surfaces only. Driving in the 4WD
LOCK and 4WD LOW positions on dry, hard-surfaced
roads may cause increased tire wear and damage to the
driveline components.
The transfer case NEUTRAL position is selected by
depressing the recessed button located on the lower left
hand corner of the 4WD Control Switch.NOTE:The transfer case NEUTRAL position is to be
used for recreational towing only. Refer to “Recreational
Towing” in this section for specific procedures on shifting
into and out of NEUTRAL.
Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster. If there are no indicator lights on or
flashing, the transfer case position is four-wheel drive
(4WD) and indicates the current and desired transfer case
selection (4WD⇔4WD LOCK).
The “SVC 4WD Warning Light” monitors the electric
shift 4WD system. If this light remains on after engine
start up or illuminates during driving, it means that the
4WD system is not functioning properly and that service
is required. See your authorized dealer for service.
