2018 DODGE DURANGO transmission

Recreational Towing — All-Wheel Drive Models
(Two-Speed Transfer Case)
The transfer case must be shifted into NEUTRAL (N) and the
transmission must be in PARK for recreational towing. The
NEUTRAL (N) selection button is adjacent to the transfer case
selector switch. Shifts into and out of transfer case NEUTRAL
(N) can take place with the selector switch in any mode position.
CAUTION!
•DO NOT dolly tow any AWD vehicle. Towing with
only one set of wheels on the ground (front or rear)
will cause severe transmission and/or transfer case
damage. Tow with all four wheels either ON the
ground, or OFF the ground (using a vehicle trailer).
• Tow only in the forward direction. Towing this
vehicle backwards can cause severe damage to the
transfer case.
• The transmission must be in PARK for recreational
towing.
• Before recreational towing, perform the procedure
outlined under “Shifting Into NEUTRAL(N)” to be
certain that the transfer case is fully in NEUTRAL
(N). Otherwise, internal damage will result.
(Continued)
CAUTION! (Continued)
•Towing this vehicle in violation of the above require-
ments can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.
• Do not use a bumper-mounted clamp-on tow bar on
your vehicle. The bumper face bar will be damaged.
Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the NEU-
TRAL (N) position without first fully engaging the
parking brake. The transfer case NEUTRAL (N) posi-
tion disengages both the front and rear driveshafts
from the powertrain and will allow the vehicle to roll,
even if the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.

On-Road Driving Tips
Utility vehicles have higher ground clearance and a nar-
rower track to make them capable of performing in a wide
variety of off-road applications. Specific design character-
istics give them a higher center of gravity than conven-
tional passenger cars.
An advantage of the higher ground clearance is a better view
of the road, allowing you to anticipate problems. They are not
designed for cornering at the same speeds as conventional
passenger cars any more than low-slung sports cars are
designed to perform satisfactorily in off-road conditions.
Avoid sharp turns or abrupt maneuvers. As with other
vehicles of this type, failure to operate this vehicle correctly
may result in loss of control or vehicle rollover.
Off-Road Driving Tips
When To Use 4WD LOW Range — If Equipped
When off-road driving, shift to 4WD LOW for additional
traction. This range should be limited to extreme situations
such as deep snow, mud, or sand where additional low speed
pulling power is needed. Vehicle speeds in excess of 25 mph
(40 km/h) should be avoided when in 4WD LOW range.
6
STARTING AND OPERATING 361

WARNING!
Do not drive in 4WD-LOW Range on dry pavement;
driveline damage may result. 4WD-LOW Range locks
front and rear drivelines together and does not allow
for differential action between the front to rear drive-
shafts. Driving in 4WD-LOW on pavement will cause
driveline binding; use only on wet or slippery surfaces.
Driving Through Water
Although your vehicle is capable of driving through water,
there are a number of precautions that must be considered
before entering the water.
CAUTION!
When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering as
a precaution, and check all fluids afterward. Driving
through water may cause damage that may not be
covered by the New Vehicle Limited Warranty.
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and pre-
vent damage to your vehicle. If you must drive through water, try to determine the depth and the bottom condition
(and location of any obstacles) prior to entering. Proceed
with caution and maintain a steady controlled speed less
than 5 mph (8 km/h) in deep water to minimize wave
effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off),
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing water avoid
depths in excess of 9 inches (23 cm). The flowing water can
erode the streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are downstream
of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 20 inches
(51 cm), and reduce speed appropriately to minimize wave
effects. Maximum speed in 20 inches (51 cm) of water is
less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
362 STARTING AND OPERATING

transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to LOW if necessary. Refer
to “All-Wheel Drive Operation” in “Starting And Operat-
ing” for further information. Do not shift to a lower gear
than necessary to maintain forward motion. Over-revving
the engine can spin the wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads, because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to LOW. Use first gear
and LOW for very steep hills.
If you stall or begin to lose forward motion while climbing
a steep hill, allow your vehicle to come to a stop and immediately apply the brakes. Restart the engine, and shift
into REVERSE. Back slowly down the hill, allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the tires.
WARNING!
If the engine stalls, you lose forward motion, or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and
rolling the vehicle. Always back carefully straight
down a hill in REVERSE gear. Never back down a hill
in NEUTRAL using only the brake.
Remember, never drive diagonally across a hill; always
drive straight up or down.
If the wheels start to slip as you approach the crest of a hill,
ease off the accelerator and maintain forward motion by
turning the front wheels slowly. This may provide a fresh
“bite” into the surface and will usually provide traction to
complete the climb.
Traction Downhill
Shift the transmission into a low gear, and the transfer case
into LOW range. Let the vehicle go slowly down the hill
6
STARTING AND OPERATING 363

with all four wheels turning against engine compression
drag. This will permit you to control the vehicle speed and
direction.
When descending mountains or hills, repeated braking can
cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual. •
Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.
