2018 DODGE DURANGO engine

Ignition Park Interlock
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. This helps the
driver avoid inadvertently leaving the vehicle without
placing the transmission in PARK. This system also locks
the transmission in PARK whenever the ignition is in the
OFF mode.
NOTE:The transmission is NOT locked in PARK when the
ignition is in the ACC mode (even though the engine will
be off). Ensure that the transmission is in PARK, and the
ignition is OFF(not in ACC mode) before exiting the
vehicle.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running and
the brake pedal must be pressed. The brake pedal must
also be pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehicle’s
overall fuel economy during normal driving conditions.
Push the “eco” button in the center stack of the instrument
panel to activate or disable ECO mode. A light on the
button indicates when ECO mode is disabled.
ECO Button
272 STARTING AND OPERATING

When the Fuel Economy (ECO) Mode is enabled, the
vehicle control systems will change the following:
•The transmission will upshift sooner and downshift
later.
• The overall driving performance will be more conserva-
tive.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
Eight-Speed Automatic Transmission
The transmission gear range is displayed both on the gear
selector and in the instrument cluster. To select a gear
range, press the lock button on the gear selector and move
the selector rearward or forward. To shift the transmission
out of PARK, the engine must be running and the brake
pedal must be pressed. You must also press the brake pedal
to shift from NEUTRAL into DRIVE or REVERSE when the
vehicle is stopped or moving at low speeds. Select the
DRIVE range for normal driving. NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission gear (for
example, driver selects PARK while driving), the position
indicator will blink continuously until the selector is re-
turned to the proper position, or the requested shift can be
completed.
The electronically-controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions. The transmission electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles
(kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped. Be
sure to keep your foot on the brake pedal when shifting
between these gears.
The transmission gear selector provides PARK, REVERSE,
NEUTRAL, DRIVE, and MANUAL (AutoStick) shift posi-
tions. Manual shifts can be made using the AutoStick shift
control. Toggling the gear selector forward (-) or rearward
(+) while in the MANUAL (AutoStick) position (beside the
DRIVE position), or tapping the shift paddles (+/-), if
equipped, will manually select the transmission gear, and
6
STARTING AND OPERATING 273

will display the current gear in the instrument cluster.
Refer to “AutoStick” in this section for further information.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 position). In MANUAL (AutoStick)
mode, the transmission gear is displayed in the instrument
cluster (as 1, 2, 3, etc.). Move the gear selector to the right
(into the DRIVE [D] position) for access to PARK, RE-
VERSE, and NEUTRAL.
Gear Ranges
Do not depress the accelerator pedal when shifting from
PARK or NEUTRAL into another gear range.
NOTE: After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating. This
is especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when exiting the vehicle in this
range.
Transmission Gear Selector
1 – Lock Button
2 – Gear Selector 274 STARTING AND OPERATING

When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.
NOTE:On vehicles equipped with the electronically
shifted transfer case, ensure that the transfer case is in
AWD AUTO or LOW RANGE position on the AWD
Control Switch. Ensure that the NEUTRAL position light is
NOT illuminated.
When exiting the vehicle, always:
• Apply the parking brake.
• Shift the transmission into PARK.
• Turn the ignition OFF.
• Remove the key fob from the vehicle.WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
• Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission is
in PARK before exiting the vehicle.
• The transmission may not engage PARK if the ve-
hicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and verify
that the transmission gear position indicator solidly
indicates PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the PARK posi-
tion is properly indicated, before exiting the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the

WARNING!(Continued)
engine is idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF mode, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.
• When exiting the vehicle, always make sure the
ignition is in the OFF mode, remove the key fob from
the vehicle, and lock the 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 trans-
mission gear selector.
(Continued)
WARNING! (Continued)
•Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
•Before moving the transmission gear selector out of
PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
• DO NOT race the engine when shifting from PARK
or NEUTRAL into another gear range, as this can
damage the drivetrain.
The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK
position:
• When shifting into PARK, push the lock button on the
gear selector and firmly move the selector all the way
forward until it stops and is fully seated.
276 STARTING AND OPERATING

•Look at the transmission gear position display and
verify that it indicates the PARK position (P), and is not
blinking.
• With brake pedal released, verify that the gear selector
will not move out of PARK.
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 position). In MANUAL (AutoStick)
mode, the transmission gear is displayed in the instrument
cluster (as 1, 2, 3, etc.). Move the gear selector to the right
(into the DRIVE [D] position) for access to PARK, RE-
VERSE, 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 if you must exit the
vehicle.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 Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.
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.
6
STARTING AND OPERATING 277

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 tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum 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.
Manual (M)
The MANUAL (M, +/-) position (beside the DRIVE posi-
tion) 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 ab-
normal 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 loca-
tion (preferably, at an authorized dealer).
278 STARTING AND OPERATING

1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shiftthe transmission to NEUTRAL.
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 recom-
mend that you visit an authorized dealer at your earliest
possible convenience. An authorized 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 pro-
viding manual shift control, giving you more control of the
vehicle. AutoStick allows you to maximize engine braking, eliminate undesirable upshifts and downshifts, and im-
prove overall vehicle performance. This system can also
provide you with more control during passing, city driv-
ing, cold slippery conditions, mountain driving, trailer
towing, and many other situations.
Operation
To activate AutoStick mode, move the gear selector into the
MANUAL (M) position (beside the DRIVE 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.
