2013 DODGE DURANGO wheel

Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
some accelerations, the clutch automatically disengages.
NOTE:
•The torque converter clutch will not engage, and the
transmission will not shift into the top overdrive gear,
until the transmission fluid and engine coolant are
warm [usually after 1 to 3 miles (2 to 5 km) of driving].
Because top gear is disabled, and engine speed is
higher when the torque converter clutch is not en-
gaged, it may seem as if the transmission is not shifting
properly when cold. This is normal. Using the Elec-
tronic Range Select (ERS) shift control, when the transmission is sufficiently warm, will demonstrate
that the transmission is able to shift into and out of
Overdrive.
• If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds after starting the
engine.
ALL-WHEEL DRIVE OPERATION
Single-Speed Operating Instructions/Precautions
(3.6L Engine) – If Equipped
This system contains a single-speed (HI range only)
transfer case, which provides convenient full-time all-
wheel drive. No driver interaction is required. The Brake
468 STARTING AND OPERATING

Traction Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE:This system is not appropriate for conditions
where LOW range is recommended. Refer to “Off-Road
Driving Tips” in “Starting and Operating” for further
information.
Electronically Shifted Transfer Case
(Three-Position Switch) (5.7L Engine) – If
Equipped
This is an electronic shift transfer case and it is operated
by the AWD Control Switch, which is located on the
center console. This electronically shifted transfer case provides three
mode positions:
•
All-wheel drive automatic range (AWD AUTO)
• All-wheel drive low range (LOW RANGE)
• Neutral (NEUTRAL)AWD Control Switch (Three-Position)
5
STARTING AND OPERATING 469

This electronically shifted transfer case is designed to be
driven in the AWD AUTO position for normal street and
highway conditions on dry hard surfaced roads.
For variable driving conditions, the AWD AUTO mode
can be used. In this mode, the front axle is engaged, but
the vehicle’s power is sent to the rear wheels. All-wheel
drive will be automatically engaged when the vehicle
senses a loss of traction.
When additional traction is required, the transfer case
LOW RANGE position can be used to lock the front and
rear driveshafts together forcing the front and rear
wheels to rotate at the same speed. This is accomplished
by rotating the AWD Control Switch to the desired
position. Refer to “Shifting Procedure” for specific shift-
ing instructions. The LOW RANGE position is designed
for loose, slippery road surfaces only. Driving in the
LOW RANGE position on dry hard surfaced roads may
cause increased tire wear and damage to the driveline
components.Transfer Case Position Indicator Messages
The Transfer Case Position Indicator messages (AWD
AUTO and LOW RANGE) are located in the EVIC
(Electronic Vehicle Information Center) and indicate the
current and desired transfer case selection. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion. When you select a different transfer case position,
the position indicator lights will do the following:
If All Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until thetransfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON.
470 STARTING AND OPERATING

If One Or More Shift Conditions Are Not Met:
1. The indicator light for the current position will remainON.
2. The newly selected position indicator light will con- tinue to flash.
3. The transfer case will notshift.
NOTE: Before retrying a selection, make certain that all
the necessary requirements for selecting a new transfer
case position have been met. To retry the selection, turn
the control knob back to the current position, wait five
seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedure for your transfer
case, located in this section of the owner’s manual.
The “SERV AWD” Warning Light” monitors the elec-
tronic shift all-wheel drive system. If this light remains on
after engine start up or illuminates during driving, it means that the all-wheel drive system is not functioning
properly and that service is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SERV AWD Warning Light”
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. This could cause
damage to driveline components.
When operating your vehicle in LOW RANGE, the
engine speed is approximately three times that of the
AWD AUTO position at a given road speed. Take care not
to overspeed the engine and do not exceed 25 mph
(40 km/h).

STARTING AND OPERATING 471

Proper operation of all-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 all-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 position without first fully engaging the
parking brake. The transfer case NEUTRAL 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:
AWD AUTO
All-Wheel Drive Auto Range – This range sends power to
the rear wheels. The all-wheel drive system will be
automatically engaged when the vehicle senses a loss of
traction. Additional traction for varying road conditions.
LOW Range
All-Wheel Drive Low Range – This range provides low
speed all-wheel drive. Locks the front and rear drive-
shafts together forcing 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).
472 STARTING AND OPERATING

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 two-wheel drive vehicles any more than
low-slung sports cars are designed to perform satisfacto-
rily in off-road conditions. If at all possible, 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 LOW Range – If Equipped
When off-road driving, shift to LOW for additional
traction. This range should be limited to extreme situa-
tions 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
LOW range.
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
driveshafts. Driving in 4WD-LOW on pavement will
cause driveline binding andcrow-hop; 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.
476 STARTING AND OPERATING

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, be-
cause 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 care-
fully straight down a hill in REVERSE gear. Never
back down a hill in NEUTRAL using only the brake.
478 STARTING AND OPERATING

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 with all four wheels turning against engine compres-
sion 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 transmis-
sion 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.
