2018 DODGE DURANGO transfer case

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

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equipment
manufacturer ’s instructions. Use of safety chains is man-
datory. Attach a tow bar or other towing device to main
structural members of the vehicle, not to bumpers or
associated brackets. State and local laws regarding vehicles
under tow must be observed. If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Manual Park Release” in this section
for instructions on shifting the transmission out of PARK
for towing or loading onto a flatbed truck.

IN CASE OF EMERGENCY 403

If flatbed equipment is not available, and the transfer case
is operable, vehicleswith a two-speed transfer case may
be towed (in the forward direction, with ALLwheels on the
ground), IFthe transfer case is in NEUTRAL (N) and the
transmission is in PARK. Refer to “Recreational Towing” in
“Starting And Operating” for detailed instructions.
Vehicles equipped with a single-speed transfer case have
no NEUTRAL position, and therefore mustbe towed will
all four wheels OFFthe ground.
CAUTION!
•Front or rear wheel lifts must not be used (if the
remaining wheels are on the ground). Internal dam-
age to the transmission or transfer case will occur if
a front or rear wheel lift is used when towing.
• 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.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced Accident
Response System.
Please refer to “Occupant Restraint Systems” in “Safety”
for further information on the Enhanced Accident Re-
sponse System (EARS) function.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an Event Data Recorder
(EDR). The main purpose of an EDR is to record data that
will assist in understanding how a vehicle’s systems per-
formed under certain crash or near crash-like situations,
such as an air bag deployment or hitting a road obstacle.
Please refer to “Occupant Restraint Systems” in “Safety”
for further information on the Event Data Recorder (EDR).7
