2008 DODGE DURANGO 4WD

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
25. Airbag Indicator
The indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned ON. If
the light does not come on when the ignition isfirst turned on, or the light stays on or comes on while
driving, have the airbag system checked by an autho-
rized dealer.
26. 4WD Indicator

272 STARTING AND OPERATING

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.
4WD
Normal Four-Wheel-Drive High Range - Employs inter-
axle differential. Allows front and rear wheels to rotate at
different speeds. All road surfaces.
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 four-wheel-drive (4WD) high range,
four-wheel-drive lock (4WD LOCK), four-wheel-drive
low (4WD LOW) range, and neutral (N).This transfer case is equipped with an inter-axle differ-
ential that allows driving the vehicle in the normal
all-wheel-drive position (4WD) at all times on any given
road surface, including dry hard surfaced roads. The
4WD mode allows the front and rear wheels to rotate at
different speeds. This eliminates driveline binding and
component wear normally associated with driving the
vehicle in the 4WD LOCK 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 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
282 STARTING AND OPERATING

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 (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 Four-Wheel Drive
(4WD) and indicate the current and desired transfer case
selection (4WD,4WD LOCK).The ªSVC 4WDº 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.
WARNING!
Always engage the parking brake when powering
down the vehicle if the(Service 4WD(light is illu-
minated. 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
STARTING AND OPERATING 283

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 4WD LOW, the engine
speed is approximately three times that of the 4WD or
4WD LOCK positions at a given road speed. Take care
not to overspeed 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.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.
284 STARTING AND OPERATING

For additional information on the appropriate use of each
transfer case mode position see the following informa-
tion:
4WD
Normal Four-Wheel-Drive High Range - Employs inter-
axle differential. Allows front and rear wheels to rotate at
different speeds. All road surfaces.
4WD LOCK
Four-Wheel-Drive Lock (4WD 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.4WD LOW
Four-Wheel-Drive Low Range (4WD LOW)- Low speed 4
wheel drive. Locks the transfer case inter-axle differen-
tial. 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.

Shifting Procedure - NV 244 Generation II
Transfer Case
NOTE:The 4x4 system will not allow shifts between
4WD/ 4WD LOCK 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 4WD LOCK position
may be experienced due to uneven tire wear, low tire
pressure, or excessive loading.
NOTE:When shifting into or out of 4WD LOW 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.
286 STARTING AND OPERATING

4WD/4WD LOCK or 2WD Models
ON
This is the normal operating mode for ESP in 4WD LOCK
and in 2WD vehicles. Whenever the vehicle is started or
the transfer case (if equipped) is shifted from 4WD LOW
or neutral back to 4WD LOCK, the ESP system will be in
this mode. This mode should be used for most all driving
situations. ESP should only be turned to ªPartial Offº for
specific reasons as noted below.
This mode is entered by momentarily
depressing the ªESP OFFº Control
Switch. When in ªPartial Offº mode,
the engine management portion of
ESP has been desensitized, the thresh-
olds for ESP activation are raised, and
the ªESP/TCS Indicator Lightº will be
illuminated. This mode is intended to
be used if the vehicle is in deep snow, sand or gravelconditions and more wheel spin than ESP would nor-
mally allow is required to gain traction. TSC (Trailer
Sway Control) is not available when the system is in the
9Partial Off9mode. To turn ESP on again, momentarily
depress the ªESP-Control OFFº Control Switch. This will
restore the normal ªONº mode of operation. ESP always
operates under braking, even with the switch in the
OFF-position.
WARNING!
In the Partial Off mode, the engine torque reduction
and stability features are desensitized. Therefore, the
enhanced vehicle stability offered by ESP is
unavailable.
NOTE:To improve the vehicle's traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the ªPartial Offº
