ECO mode DODGE DURANGO 2007 2.G Workshop Manual

WARNING!
It is dangerous to shift the selector lever out of “P” or
“N” 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 re-
verse. 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.
“R” Reverse
Use this range only after the vehicle has come to a
complete stop.“N” Neutral
Shift to Neutral when vehicle is standing for prolonged
periods with engine running. Engine may be started in
this range. Set the parking brake if you must leave the
vehicle.
NOTE:Towing the vehicle (except as specified under
Towing A Disabled Vehicle), coasting, or otherwise driv-
ing the vehicle while in N (Neutral) can cause severe
transmission damage
“D” 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 miles per
hour (72 km/h) in this range.
256 STARTING AND OPERATING

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 improveperformance 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” 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 “TOW/HAUL” 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
258 STARTING AND OPERATING

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 Over-
drive and in Drive.
NOTE:The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
[usually 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 transmission
is not shifting into Overdrive when cold. This is normal.
Pressing theTOW/HAULbutton will demonstrate that
the transmission is able to shift into and out of Overdrive.
NOTE:If the vehicle has not been driven in several
days, the first few seconds of operation after shifting the
transmission into gear may seem sluggish. This is due tothe fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds of shifting from Park into
any other gear position.
FOUR-WHEEL DRIVE OPERATION
NV 144 Transfer Case Operating
Information/Precautions
The NV 144 is an electric shift transfer case and is
operated by the Four-Wheel-Drive (4WD) Control
Switch, which is located on the instrument panel.
The NV 144 transfer case provides 2 mode positions:
Four-Wheel Drive (4WD) and 4-Wheel-Drive Lock (4WD
LOCK).
The NV 144 transfer case is designed to be driven in for
4WD for normal street and highway conditions (all road
surfaces roads).

CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.
WARNING!
Attaching a snowplow to this vehicle could ad-
versely affect performance of the airbag system in an
accident. Do not expect that the airbag will perform
as described earlier in this manual
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Recreational Towing 2WD Models
Recreational towing of 2WD models is not allowable.
Towing the vehicle with the transmission in Neutral can
cause severe transmission damage. Removal of the drive-
shaft for towing is not recommended since this allows
transmission fluid to leak out.
Recreational Towing 4WD Models
CAUTION!
Vehicles equipped with an NV 144 Transfer Case
(which has no neutral position) may NOT be used
for recreational towing.

NOTE:Items 1 through 5 are requirements that must be
met prior to depressing the Neutral (N) selection button,
and must continue to be met until 1 second elapses and
the shift has been completed.
If any of these requirements are not met prior to depress-
ing the Neutral (N) button or are no longer met during
the 1 second time, then all of the position indicator lights
will flash continuously until all requirements are met or
until the Neutral (N) button is released.
NOTE:The ignition key must be ON for a shift to take
place and for the position indicator lights to be operable.
If the key is not On, the shift will not take place and no
position indicator lights will be on or flashing.
NOTE:Flashing neutral (N) position indicator light
indicates that shift requirements have not been met.CAUTION!
•Do not use a bumper mounted clamp-on tow bar on
your vehicle. The bumper face bar will be damaged.
•Do not disconnect the rear driveshaft because fluid
will leak from the transfer case and damage internal
parts.
EQUIPMENT IDENTIFICATION PLATE
The equipment Identification Plate is located on the hood
inner surface.
The following information about your vehicle is dis-
played on this plate: Model, Wheelbase, Vehicle Identifi-
cation Number, Truck Order Number, and code numbers
with descriptions of all production and special equip-
ment on the truck as shipped from the factory.
NOTE:Always refer to the equipment identification
plate when ordering parts.

VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Power Distribution Center (PDC). The
I.O.D. cavity includes a snap-in retainer that allows the
fuse to be disconnected, without removing it from the
fuse block.
•The transfer case should be placed in the 4HI mode
and kept in this position to minimize the battery drain.
•As an alternative to the above steps you may discon-
nect the negative cable from the battery.
