2020 DODGE DURANGO engine

196STARTING AND OPERATING
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position (when
pushed forward) it is probably in the MANUAL
(AutoStick, +/-) position (beside the DRIVE posi -
tion). In MANUAL (AutoStick) mode, the trans -
mission gear is displayed in the instrument
cluster (as 1, 2, 3, etc.). Move the gear selector
to the right (into the DRIVE position) for access
to PARK, REVERSE, and NEUTRAL.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running.
Apply the parking brake and shift the
transmission into PARK (P) if you must exit the
vehicle. DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically
upshifts through all forward gears. The DRIVE position provides optimum driving
characteristics under all normal operating
conditions.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain,
traveling into strong head winds, or while towing
a heavy trailer), use the AutoStick shift control
(refer to AutoStick in this section for further
information) to select a lower gear. Under these
conditions, using a lower gear will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
During cold temperatures, transmission
operation may be modified depending on
engine and transmission temperature as well
as vehicle speed. This feature improves warm
up time of the engine and transmission to
achieve maximum efficiency. Engagement of
the torque converter clutch is inhibited until the
transmission fluid is warm. Normal operation
will resume once the transmission temperature
has risen to a suitable level.WARNING!
Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You might
lose control of the vehicle and have a
collision.
CAUTION!
Towing the vehicle, coasting, or driving for any
other reason with the transmission in
NEUTRAL can cause severe transmission
damage.
Refer to “Recreational Towing” in “Starting
And Operating” and “Towing A Disabled
Vehicle” in “In Case Of Emergency” for further
information.

STARTING AND OPERATING197
Manual (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of
transmission shifting (also known as AutoStick
mode; refer to “AutoStick” in this section for
further information). Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL
(AutoStick) position will manually select the
transmission gear, and will display the current
gear in the instrument cluster as 1, 2, 3, etc.
Transmission Limp Home Mode
Transmission function is monitored
electronically for abnormal conditions. If a
condition is detected that could result in
transmission damage, Transmission Limp
Home Mode is activated. In this mode, the
transmission may operate only in certain gears,
or may not shift at all. Vehicle performance may
be severely degraded and the engine may stall.
In some situations, the transmission may not
re-engage if the engine is turned off and
restarted. The Malfunction Indicator Light (MIL)
may be illuminated. A message in the
instrument cluster will inform the driver of the
more serious conditions, and indicate what
actions may be necessary. In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage
after engine shutdown, perform this procedure
only in a desired location (preferably, at an
authorized dealer).

1. Stop the vehicle.

2. Shift the transmission into PARK (P), if
possible. If not, shift the transmission to
NEUTRAL (N).
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the
transmission will return to normal
operation. NOTE:
Even if the transmission can be reset, we
recommend that you visit an authorized dealer
at your earliest possible convenience. An autho
-
rized dealer has diagnostic equipment to
assess the condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
AutoStick
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving
you more control of the vehicle. AutoStick
allows you to maximize engine braking,
eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This
system can also provide you with more control
during passing, city driving, cold slippery
conditions, mountain driving, trailer towing, and
many other situations.

198STARTING AND OPERATING
Operation
To activate AutoStick mode, move the gear
selector into the MANUAL (M) position (beside
the DRIVE (D) position), or tap one of the shift
paddles on the steering wheel (if equipped).
Tapping the (-) shift paddle (if equipped) to
enter AutoStick mode will downshift the
transmission to the next lower gear, while
tapping (+) to enter AutoStick mode will retain
the current gear. The current transmission gear
will be displayed in the instrument cluster. In
AutoStick mode, you can use the gear selector
(in the MANUAL position), or the shift paddles (if
equipped), to manually shift the transmission.
Tapping the gear selector forward (-) while in the
MANUAL (M) position, or tapping the (-) shift
paddle (if equipped), will downshift the
transmission to the next lower gear. Tapping the
selector rearward (+) or tapping the (+) shift
paddle (if equipped) will command an upshift.
NOTE:
The shift paddles (if equipped) may be disabled
(or re-enabled, as desired) using the Uconnect
Personal Settings. In AutoStick mode, the transmission will shift up
or down when (+/-) is manually selected by the
driver, unless an engine lugging or overspeed
condition would result. It will remain in the
selected gear until another upshift or downshift
is chosen, except as described below.
The transmission will automatically down
-
shift as the vehicle slows (to prevent engine
lugging) and will display the current gear.
The transmission will automatically down -
shift to FIRST gear when coming to a stop.
After a stop, the driver should manually
upshift (+) the transmission as the vehicle is
accelerated.
You can start out, from a stop, in FIRST or
SECOND gear. Tapping (+) at a stop will allow
starting in SECOND gear. Starting out in
SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at
too low of a vehicle speed.
Holding the (-) paddle depressed (if
equipped), or holding the gear selector in the
(-) position, will downshift the transmission to
the lowest gear possible at the current
speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift
mode if a fault or overheat condition is
detected.
To disengage AutoStick mode, return the gear
selector to the DRIVE (D) position, or press and
hold the (+) shift paddle (if equipped, and if the
gear selector is already in DRIVE) until "D" is
once again indicated in the instrument cluster.
You can shift in or out of AutoStick mode at any
time without taking your foot off the accelerator
pedal.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the vehicle
could skid, causing a collision or personal
injury.

STARTING AND OPERATING199
SPORT MODE — IF EQUIPPED
Your vehicle is equipped with a Sport Mode
feature. This mode is a configuration set up for
typical enthusiast driving. The engine,
transmission, and steering systems are all set
to their SPORT settings. Sport Mode will provide
improved throttle response and modified
transmission shift points for an enhanced
driving experience, as well as greater amount of
steering feel. This mode may be activated and
deactivated by pushing the Sport button on the
instrument panel switch bank.
ALL-WHEEL DRIVE OPERATION
SINGLE-SPEED OPERATING
I
NSTRUCTIONS/PRECAUTIONS— IF
E
QUIPPED
This system contains a single-speed (HI range
only) transfer case, which provides convenient
full-time All-Wheel Drive (AWD). No driver
interaction is required. The Brake 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
“Driving Tips” in this chapter for further informa-
tion.
ELECTRONICALLY SHIFTED TRANSFER
C
ASE (THREE-POSITION SWITCH) — IF
E
QUIPPED
This is an electronically shifted transfer case
and it is operated by the AWD Control Switch,
which is located on the center console.

AWD Control Switch (Three-Position)
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 instructions.
5

20_WD_OM_EN_USC_t.book Page 199

200STARTING AND OPERATING
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 “Getting To
Know Your Instrument Panel” for further
information. 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 shift conditions are not met, one or more of
the following events may occur:

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 not shift.
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 requirements, refer
to the "Shifting Procedure" for your transfer
case, located in this section.
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. 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.
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.

20_WD_OM_EN_USC_t.book Page 200

202STARTING AND OPERATING
Preferred Procedure

1. With the engine running, slow the vehicle
to 2 to 3 mph (3 to 5 km/h).

2. Shift the transmission into NEUTRAL.
3. While still rolling, rotate the AWD control switch to the desired position.
4. After the desired position indicator light is on (not flashing), shift the transmission
back into gear.
Alternate Procedure

1. Bring the vehicle to complete stop.

2. With the ignition in ON/RUN position and engine running, shift the transmission to
NEUTRAL.
3. Rotate the AWD control switch to the desired position.
4. After the desired position indicator light is on (not flashing), shift the transmission
back into gear. NOTE:
If steps 1 or 2 of either the Preferred or Alter
-
nate Procedure are not satisfied prior to
attempting the shift or if they no longer are
being met while the shift attempt is in
process, the desired position indicator light
will flash continuously while the original posi -
tion indicator light is on, until all require -
ments have been met.
The ignition switch must be in the ON/RUN
position for a shift to take place and for the
position indicator lights to be operable. If the
ignition switch is not in the ON/RUN position,
then the shift will not take place and no posi -
tion indicator lights will be on or flashing.
NEUTRAL Shift Procedure
For information regarding the transfer case
NEUTRAL (N) shift procedure, refer to “Shifting
Into NEUTRAL (N)” in “Recreational Towing” in
this chapter.
FUEL SAVER TECHNOLOGY 5.7L/6.4L ONLY
— IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The
system is automatic with no driver inputs or
additional driving skills required.
NOTE:
This system may take some time to return to full
functionality after a battery disconnect.
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.

20_WD_OM_EN_USC_t.book Page 202

STARTING AND OPERATING203
Alternate electric power steering efforts can be
selected through the Uconnect System. Refer to
”Customer Programmable Features” within
“Uconnect Settings” in “Multimedia” for further
information.
If the Electric Power Steering warning
icon is displayed and the “SERVICE
POWER STEERING” or the “POWER
STEERING ASSIST OFF – SERVICE
SYSTEM” message is displayed within the
instrument cluster display, this indicates the
vehicle needs to be taken to the dealer for
service. Refer to “Warning Lights And
Messages” in “Getting To Know Your
Instrument Panel” for further information. NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer
the vehicle. Under these conditions there will
be a substantial increase in steering effort,
especially at low speeds and during parking
maneuvers.
If the condition persists, see an authorized
dealer for service.
If the Steering icon is displayed and the
“POWER STEERING SYSTEM OVER TEMP”
message is displayed on the instrument cluster
screen, they indicate that extreme steering
maneuvers may have occurred which caused
an over temperature condition in the power
steering system. Once driving conditions are
safe, pull over and let the vehicle idle for a few
moments until the icon and message turn off.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce
fuel consumption. The system will stop the
engine automatically during a vehicle stop if the
required conditions are met. Releasing the
brake pedal or pressing the accelerator pedal
will automatically re-start the engine. This vehicle has been upgraded with a heavy
duty starter, enhanced battery, and other
upgraded engine parts, to handle the additional
engine starts.
AUTOMATIC MODE
The Stop/Start feature is enabled
after every normal customer engine
start. At that time, the system will go
into STOP/START READY and if all
other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
The system must be in STOP/START READY
state. A STOP/START READY message will be
displayed in the instrument cluster display
within the Stop/Start section. Refer to
“Instrument Cluster” in “Getting To Know
Your Instrument Panel” for further informa -
tion.
The vehicle must be completely stopped.
The gear selector must be in a forward gear
and the brake pedal depressed.
WARNING!
Continued operation with reduced assist
could pose a safety risk to yourself and
others. Service should be obtained as soon
as possible.
