2005 DODGE DURANGO lock

NOTE:Delayed shifting out of 4LOCK may be experi-
enced due to uneven tire wear, low tire pressure, or
excessive vehicle loading.
NOTE:If any of the requirements to select a new
transfer case position have not been met, the transfer case
will not shift.The indicator light will flash and the current
transfer case position will be maintained.To retry a
selection, turn the control knob back to the current
position, wait five (5) seconds, and retry the shift.
NOTE:The 4x4 system will not allow shifts between
AWD/4LOCK if the rear wheels are spinning (no trac-
tion). In this situation the position indicator light will
continue to flash. At this time, reduce speed and stop
spinning the wheels to complete the shift. There may be
a delay up to 13 seconds for the shift to complete after the
wheels have stopped spinning.
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 then the shift will not take place and
no position indicator lights will be on or flashing.
NV 244 Generation II Transfer Case Operating
Information / Precautions
The NV 244 Generation II is an electric shift transfer case
and is operated by the 4WD Control Switch, which is
located on the instrument panel.
The NV 244 Generation II transfer case provides 4 mode
positions - Normal all-wheel-drive high range, four-
wheel-drive LOCK, four-wheel-drive low range, and
neutral.
This transfer case is equipped with an inter-axle differ-
ential that allows driving the vehicle in the normal
all-wheel-drive position (AWD) at all times on any given
road surface, including dry hard surfaced roads. The
AWD mode allows the front and rear wheels to rotate at
different speeds. This eliminates driveline binding and
component wear normally associated with driving the
STARTING AND OPERATING 229

vehicle in the 4LOCK position on dry hard surfaced
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 4LOCK and
4LO 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 4LOCK and
4LO positions are intended for loose, slippery road
surfaces only. Driving in the 4LOCK and 4LO positions
on dry hard surfaced roads may cause increased tire wear
and damage to the driveline components.
The transfer case Neutral (N) 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 (N) position is to be
used for recreational towing only. See Recreational Tow-
ing section for specific procedures on shifting into and
out of Neutral (N).
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 All-Wheel Drive
(AWD) and indicate the current and desired transfer case
selection (4HI⇔4LOCK).
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.
230 STARTING AND OPERATING

WARNING!
Always engage the parking brake when powering
down the vehicle if theService 4WDlight is
illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The NV 244 Generation
II transfer case is not equipped with a synchronizer and
therefore the front and rear driveshaft speeds must be
equal for the shift to take place. Shifting while only the
front or rear wheels are spinning can cause damage to the
transfer case.
When operating your vehicle in 4LO, the engine speed is
approximately three times that of the AWD or 4LOCKpositions at a given road speed. Take care not to over-
speed the engine and do not exceed 40 km/h (25 mph).
Proper operation of four-wheel-drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
STARTING AND OPERATING 231

WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position see the information below:
AW D
Normal All-Wheel-Drive High Range - Employs inter-
axle differential. Allows front and rear wheels to rotate at
different speeds. All road surfaces.4LOCK
Four-Wheel-Drive LOCK - Locks the transfer case inter-
axle differential. Forces front and rear wheels to rotate at
the same speed. Additional traction for loose, slippery
road surfaces only.
4LO
Four-Wheel-Drive Low Range - Low speed 4 wheel
drive. Locks the transfer case inter-axle differential.
Forces the front and rear wheels to rotate at the same
speed. Additional traction and maximum pulling power
for loose, slippery road surfaces only. Do not exceed 25
mph (40 km/h).
N
Neutral - Disengages both the front and rear driveshafts
from the powertrain. To be used for flat towing behind
another vehicle. See Recreational Towing for more infor-
mation.
232 STARTING AND OPERATING

Shifting Procedure - NV 244 Generation II
Transfer Case
NOTE:The 4x4 system will not allow shifts between
AWD/ 4LOCK if the rear wheels are spinning (no
traction). In this situation a position indicator light will
flash and the original position indicator light will remain
ON. At this time, reduce speed and stop spinning thewheels to complete the shift. There may be a delay up to
13 seconds for the shift to complete after the wheels have
stopped spinning.
NOTE:Delayed shifting out of the 4LOCK position may
be experienced due to uneven tire wear, low tire pressure,
or excessive loading.
NOTE:When shifting into or out of 4LO some gear
noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
Shifting can be performed with the vehicle rolling 2 to 3
mph (3 to 5 km/h) or completely stopped. USE EITHER
OF THE FOLLOWING PROCEDURES:
Preferred Procedure
1. With the engine RUNNING, slow vehicle to 2 to 3
mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.

Be sure the parking brake is firmly set when parked and
the gear-shift lever is in PARK position. When parking on
a hill you should apply the Parking Brake before placing
the gear shift lever in PARK; otherwise the load on the
transmission locking mechanism may make it difficult to
move the selector out of PARK.NOTE:The instrument cluster brake warning light
indicates only that the parking brake is applied. You must
be sure the parking brake is fully applied before leaving
the vehicle.
When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should be applied whenever the
driver is not in the vehicle.

WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or vehicle may roll and cause
damage or injury. Also be certain to leave an
automatic transmission in Park. Failure to do so
may cause the vehicle to roll and cause damage or
injury.
•Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
failure and an accident.
•Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector
lever. Don’t leave the key in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
BRAKE SYSTEM
In the event power assist is lost for any reason, (for
example, repeated brake applications with the engine
off), the brakes will still function. The effort required to
brake the vehicle will be significantly increased over that
required with the power system operating.
If either the front or rear hydraulic systems lose normal
capability, the remaining system will still function with
some loss of braking effectiveness. This will be evident by
increased pedal travel during application, greater pedal
force required to slow or stop, and activation of the Brake
Warning Lamp and the ABS Lamp during brake use.
Four-Wheel Anti-Lock Brake System (ABS)
This Anti-Lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lockup and help avoid skidding on slippery surfaces.
236 STARTING AND OPERATING

The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The Anti-Lock Brake system includes an amber (ABS)
warning light. When the light is illuminated, the Anti-
Lock Brake system is not functioning. The system reverts
to standard non-anti-lock brakes. Turning the ignition Off
and On again may reset the Anti-Lock Brake system if the
fault detected was only momentary.WARNING!
Anti-Lock Brake Systems contain sophisticated elec-
tronic equipment. It may be susceptible to interfer-
ence caused by improperly installed or high output
radio transmitting equipment. This interference can
cause possible loss of anti-lock braking capability.
Installation of such equipment should be done by
qualified professionals.
WARNING!
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
