wheel DODGE DURANGO 2017 3.G Workshop Manual

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)
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 shifting instruc-
tions. 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 instrument
cluster and indicate the current and desired transfer case
selection. Refer to “Instrument Cluster Display” 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 the transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON.
If One Or More Shift Conditions Are Not Met:
1. The indicator light for the current position will remain ON.
2. The newly selected position indicator light will continue to flash.
3. The transfer case will notshift.
396 STARTING AND OPERATING

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 sec-
onds, and retry selection. To find the shift requirements,
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 electronic
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).
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.
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 auto-
matically engaged when the vehicle senses a loss of trac-
tion. 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 driveshafts
together forcing the front and rear wheels to rotate at the

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 satisfactorily
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 trac-
tion. 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 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
(Continued)
WARNING!(Continued)
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
400 STARTING AND OPERATING

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 in (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 in (51 cm),
and reduce speed appropriately to minimize wave effects.
Maximum speed in 20 in (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,
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
5
STARTING AND OPERATING 401

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
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.
402 STARTING AND OPERATING

•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.
ELECTRIC POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
Alternate electric power steering efforts can be selected
through the Uconnect System. Refer to ”Customer Pro-
grammable Features” within “Uconnect Settings” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
If the Electric Power Steering warning icon is
displayed and the “SERVICE POWER STEER-
ING” or the “POWER STEERING ASSIST OFF –
SERVICE SYSTEM” message is displayed within
the instrument cluster, this indicates the vehicle needs to be
taken to the dealer for service. Refer to “Instrument Clus-
ter” in “Understanding Your Instrument Panel” for further
information.
5
STARTING AND OPERATING 403

NOTE:
•When the parking brake is applied and the transmission
is placed in gear, the “Brake” Warning Light will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied.
It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking brake
before placing the gear selector in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.
WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
(Continued)
WARNING! (Continued)
•When leaving the vehicle, always remove the key fob
from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
• When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, remove
the key fob from the vehicle and lock the vehicle.
• Do not leave the key fob in or near the vehicle or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
• Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.

STARTING AND OPERATING 405

WARNING!(Continued)
•Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the “Brake” Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake sys-
tems. If either of the two hydraulic systems loses normal
capability, the remaining system will still function. How-
ever, there will be some loss of overall braking effective-
ness. You may notice increased pedal travel during appli-
cation, greater pedal force required to slow or stop, and
potential activation of the “Brake System Warning Light.” In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the brakes
will still function. However, the effort required to brake the
vehicle will be much greater than that required with the
power system operating.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Electronic Stability
Control (ESC), and Electronic Roll Mitigation (ERM). These
systems work together to enhance both vehicle stability
and control in various driving conditions.
Your vehicle may also be equipped with Trailer Sway
Control (TSC), Ready Alert Braking (RAB), Rain Brake
Support (RBS), and Dynamic Steering Torque (DST).
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the braking
torque between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip of
the rear wheels to avoid vehicle instability, and to prevent
the rear axle from entering ABS before the front axle.
406 STARTING AND OPERATING

Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition switch is turned to the ON position and may
stay on for as long as four seconds.
If the “Brake System Warning Light” remains on or comes
on while driving, it indicates that the brake system is not
functioning properly and that immediate service is re-
quired. If the “Brake System Warning Light” does not come
on when the ignition switch is turned to the ON position,
have the light repaired as soon as possible.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most brak-
ing conditions. The system automatically prevents wheel
lock, and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that the ABS
is working properly each time the vehicle is started and
driven. During this self-check, you may hear a slight
clicking sound as well as some related motor noises.
ABS is activated during braking when the system detects one
or more wheels begins to lock. Road conditions such as ice,
snow, gravel, bumps, railroad tracks, loose debris, or panic
stops may increase the likelihood of ABS activation(s).
You also may experience the following when ABS activates:
•The ABS motor noise (it may continue to run for a short
time after the stop).
• The clicking sound of solenoid valves.
• Brake pedal pulsations.
• A slight drop of the brake pedal at the end of the stop.
These are all normal characteristics of ABS.
WARNING!
• The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference caused
by improperly installed or high output radio trans-
mitting equipment. This interference can cause pos-
sible loss of anti-lock braking capability. Installation
of such equipment should be performed by qualified
professionals.

Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
•
For vehicles equipped with the Instrument Cluster Dis-
play, refer to “Instrument Cluster Display” in “Under-
standing Your Instrument Panel” for further information.
• If disabling HSA using Uconnect Settings, refer to
“Uconnect Settings” in “Understanding Your Instrument
Panel” for further information.
For vehicles not equipped with the instrument cluster
display, perform the following steps:
1.
Center the steering wheel (front wheels pointing straight
forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left. 6. Push the “ESC Off” button located in the lower switch
bank below the climate control four times within twenty
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slighty more than one-half turn to the right.
8. Turn the ignition switch to the OFF position and then back to the ON position. If the sequence was completed
properly, the “ESC Off Indicator Light” will blink sev-
eral times to confirm HSA is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
