AutoPark — Rotary Shifter and 8-Speed
Trans Only
AutoPark is a supplemental feature to assist
in placing the vehicle in PARK should the
situations on the following pages occur. It is a back up system and should not be relied
upon as the primary method by which the
driver shifts the vehicle into PARK.
The conditions under which AutoPark will
engage are outlined on the following pages.
WARNING!
• Driver inattention could lead to failure to
place the vehicle in PARK. ALWAYS DO
A VISUAL CHECK that your vehicle is in
PARK by verifying that a solid (not blink-
ing) “P” is indicated in the Instrument
Cluster Display and near the gear selec-
tor. If the "P" indicator is blinking, your
vehicle is not in PARK. As an added
precaution, always apply the parking
brake when exiting the vehicle.
• AutoPark is a supplemental feature. It is
not designed to replace the need to shift
your vehicle into PARK. It is a back up
system and should not be relied upon as
the primary method by which the driver
shifts the vehicle into PARK. If the vehicle is not in PARK and the driver turns
off the engine, the vehicle may AutoPark.
AutoPark will engage when all of these con-
ditions are met:
• Vehicle is equipped with a rotary shifter and
an 8-speed transmission
• Vehicle is not in PARK
• Vehicle Speed is 1.2 MPH (1.9 km/h) or less
• Ignition switched from RUN to ACC
NOTE:
For Keyless Go equipped vehicles, The en-
gine will turn off and the ignition switch will
change to ACC mode. After 30 minutes the
ignition switches to OFF automatically, un-
less the driver turns the ignition switch OFF.
If the vehicle is not in PARK and the driver exits
the vehicle with the engine running, the vehicle
may AutoPark.
AutoPark will engage when all of these con-
ditions are met:
• Vehicle is equipped with a rotary shifter and an 8-speed transmission

• Vehicle is not in PARK
• Vehicle speed is 1.2 MPH (1.9 km/h) orless
• Driver’s seat belt is unbuckled
• Driver’s door is ajar
• Brake Pedal is not depressed
The MESSAGE “AutoPark Engaged Shift to P
then Shift to Gear” will display in the instru-
ment cluster.
NOTE:
In some cases the ParkSense graphic will be
displayed in the instrument cluster, causing
the “AutoPark Engaged Shift to P then Shift to
Gear” to not be seen. In these cases, the
shifter must be returned to “P” to select
desired gear.
If the driver shifts into PARK while moving, the
vehicle may AutoPark.
AutoPark will engage ONLYwhen vehicle
speed is 1.2 MPH (1.9 km/h) or less.
The MESSAGE “Vehicle Speed is Too High to
Shift to P”will be displayed in the instrument
cluster if vehicle speed is above 1.2 MPH
(1.9 km/h).WARNING!
If vehicle speed is above 1.2 MPH
(1.9 km/h), the transmission will default to
NEUTRAL until the vehicle speed drops
below 1.2 MPH (1.9 km). A vehicle left in
the NEUTRAL position can roll. As an
added precaution, always apply the park-
ing brake when exiting the vehicle.
4WD LOW — If Equipped
AutoPark will be disabled when operating the
vehicle in 4WD LOW.
The MESSAGE “AutoPark Disabled” will be
displayed in the instrument cluster.
Additional customer warnings will be given
when all of these conditions are met:
• Vehicle is not in PARK
• Driver’s Door is ajar
• Vehicle is in 4WD LOW range
The MESSAGE “AutoPark Not Engaged” will
be displayed in the instrument cluster. A
warning chime will continue until you shift
the vehicle into PARK or the Driver’s Door is
closed. ALWAYS DO A VISUAL CHECK
that your vehicle
is in PARK by looking for the "P" in the
Instrument Cluster Display and near the
shifter. As an added precaution, always apply
the parking brake when exiting the vehicle.
Extreme Cold Weather
The engine block heater is a resistance heater
installed in the water jacket of the engine. It
requires a 110–115 Volt AC electrical outlet
with a grounded, three-wire extension cord.
Its use is recommended for environments
that routinely fall below -10°F (-23°C). It
should be used when the vehicle has not been
running overnight or longer periods and
should be plugged in two hours prior to start.
Its use is required for cold starts with tem-
peratures under -20°F (-28°C).
NOTE:
The engine block heater cord is a factory
installed option. If your vehicle is not
equipped, heater cords are available from
your authorized Mopar dealer.
• A 12 Volt heater built into the fuel filter housing aids in preventing fuel gelling. It is
controlled by a built-in thermostat.

Supplement for more information.
To Turn Off The Engine Using ENGINE START/
STOP Button
1. Place the gear selector in PARK, then push and release the ENGINE START/
STOP button.
2. The ignition will return to the OFF mode.
3. If the gear selector is not in PARK and the ENGINE START/STOP button is pushed
once, the instrument cluster will display a
“Vehicle Not In Park” message and the
engine will remain running. Never leave a
vehicle out of the PARK position, or it
could roll.
4. If the gear selector is in NEUTRAL, and the vehicle speed below 5 mph (8 km/h),
pushing the START/STOP button once will
turn the engine off. The ignition will re-
main in the ACC mode.
5.
If the vehicle speed is above 5 mph (8 km/h),
the ENGINE START/STOP button must be held for two seconds (or three short pushes
in a row) to turn the engine off. The ignition
will remain in the ACC mode (NOT the OFF
mode) if the engine is turned off when the
transmission is not in PARK.
NOTE:
If the ignition is left in the ACC or ON/RUN
(engine not running) mode and the transmis-
sion is in PARK, the system will automatically
time out after 30 minutes of inactivity and
the ignition return to the OFF mode.
ENGINE START/STOP Button Functions — With
Driver’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates
similar to an ignition switch. It has three
positions, OFF, ACC, RUN. To change the
ignition switch positions without starting the
vehicle and use the accessories follow these
steps:
1. Starting with the ignition in the OFF
position:
2. Push the ENGINE START/STOP button once to change the ignition to the ACC
position. 3. Push the ENGINE START/STOP button a
second time to change the ignition to the
RUN position.
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF
position.
Keyless Enter-N-Go Starting Procedure —
Engine Manifold Air Temperature 0° F To
66° F (–18° C to 19° C)
NOTE:
The temperature displayed in the instrument
cluster does not necessarily reflect the en-
gine manifold air temperature. Refer to “In-
strument Cluster Display” in “Getting To
Know Your Instrument Panel” for further in-
formation. When engine temperatures fall
below 66°F (19°C) the “Wait To Start Light”
will remain on indicating the intake manifold
heater system is active.
Follow the steps in the “Normal Starting”
procedure except:
1. Pushing the engine start button with thedriver’s foot on the brake will move the
147

ignition from OFF or ACC to RUN, and will
illuminate the "Wait To Start" telltale. The
engine will not immediately crank, this is
normal operation.
2. The “Wait To Start" telltale will remain on for a period of time that varies depending
on the engine temperature.
3. While the "Wait to Start" telltale is on, the instrument cluster will additionally dis-
play a gauge or bar whose initial length
represents the full "Wait to Start" time
period. Its length will decrease until it
disappears when the "Wait to Start" time
has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
you drain the water from the fuel filters to
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Dealer
Service” under “Servicing And Mainte-
nance” for further information. 4. After the engine “Wait To Start” telltale
goes off, the engine will automatically
crank.
CAUTION!
Do not crank engine for more than 15 sec-
onds at a time or starter motor damage
may result. Turn the ignition switch to the
OFF position and wait at least two minutes
for the starter to cool before repeating start
procedure.
5. After engine start-up, check to see that there is oil pressure.
6. Allow the engine to idle about three min- utes until the manifold heaters have com-
pleted the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically in- crease to 1,000 RPM and engage the Vari-
able Geometry Turbocharger at low coolant
temperatures to improve engine warm-up. • The engine may not automatically crank
after the engine "Wait To Start" telltale goes
off if a door or the hood is ajar.
• If the engine stalls, or if the ignition switch is left ON for more than two minutes after
the “Wait To Start Light” goes out, reset the
grid heaters by turning the ignition switch
to the OFF position for at least five seconds
and then back ON. Repeat steps 1 through
7 of “Keyless Enter-N-Go Starting Proce-
dure – Engine Manifold Air Temperature
Below 66° F (19° C).”
Extreme Cold Weather
The Cummins diesel engine is equipped with
several features designed to assist cold
weather starting and operation:
• The engine block heater is a resistance
heater installed in the water jacket of the
engine just above and behind the oil filter.
It requires a 110–115 Volt AC electrical
outlet with a grounded, three-wire exten-
sion cord.STARTING AND OPERATING
148

to maintain normal system voltage by auto-
matically increasing engine idle speed. You
may notice several consecutive increases in
idle speed, up to a maximum of 1450 RPM,
as the system will attempt to utilize the
smallest increase in idle speed necessary to
maintain normal system voltage. The idle
speed will return to normal when either the
electrical load is removed, or when the brake
pedal is applied.
NOTE:
For instrument cluster display messages re-
lated to the vehicle's exhaust system, refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further in-
formation.
Idle-Up Feature — Automatic Transmission
Only
The driver-controlled high idle speed feature
will help increase cylinder temperatures and
provide additional cab heat, however, exces-
sive idling may still cause the exhaust after-
treatment system to not properly regenerate.
Extended periods of idle time should be
avoided.The Idle-Up feature uses the speed control
switches to increase engine idle speed and
quickly warm the vehicle's interior.
1. With the transmission in PARK, the park-
ing brake applied, and the engine run-
ning, push the speed control switch to the
ON position, then push the SET switch.
2. The engine RPM will go up to 1100 RPM. To increase the RPM, push and hold the
ACCEL/RESUME switch and the idle
speed will increase to approximately
1500 RPM. To decrease the RPM, push
and hold the DECEL switch and the idle
speed will decrease to approximately
1100 RPM.
3. To cancel the Idle–Up feature, either push the CANCEL switch, push the ON/OFF
switch, or press the brake pedal.Stopping The Engine
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricat- ing oil and coolant to carry excess heat away
from the combustion chamber, bearings, in-
ternal components, and turbocharger. This is
especially important for turbocharged,
charge air-cooled engines.
NOTE:
• During engine shut down on vehicles
equipped with manual transmissions, it is
normal for the diesel engine to resonate
heavily for a moment during engine shut
off. When the engine is connected to a
manual transmission, this resonance
causes load gear rattle from the transmis-
sion. This is commonly referred to as “shut
down rattle.” The manufacturer recom-
mends performing engine shut down with
the clutch pedal pushed to the floor (clutch
disengaged). When engine shut down is
performed in this manner the rattle is re-
duced (not eliminated).
• Refer to the following chart for proper en- gine shutdown.
STARTING AND OPERATING
152

NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the LOCK/OFF (key removal) posi-
tion. The key fob can only be removed from
the ignition when the ignition is in the LOCK/
OFF position, and the transmission is locked
in PARK whenever the ignition is in the
LOCK/OFF position.
NOTE:
If a malfunction occurs, the system will trap
the key fob in the ignition to warn you that
this safety feature is inoperable. The engine
can be started and stopped but the key fob
cannot be removed until you obtain service.
Brake/Transmission Shift
Interlock System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock System (BTSI) that
holds the transmission gear selector in PARKunless the brakes are applied. To shift the
transmission out of PARK, the ignition must
be turned to the ON/RUN mode (engine run-
ning, for vehicles with eight-speed transmis-
sion) and the brake pedal must be pressed.
In 8-speed vehicles, 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.
Eight-Speed Automatic
Transmission — If Equipped
The transmission is controlled using a rotary
electronic gear selector located on the instru-
ment panel. The transmission gear range
(PRND) is displayed both above the gear
selector and in the instrument cluster. To
select a gear range, simply rotate the gear
selector. You must press the brake pedal to
shift the transmission out of PARK (or NEU-
TRAL, when the vehicle is stopped or moving
at low speeds). To shift past multiple gear
ranges at once (such as PARK to DRIVE),
simply rotate the gear selector to the appro-
priate detent. 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 con-
tinuously until the selector is returned 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 be-
tween these gears.
The transmission gear selector has only
PARK, REVERSE, NEUTRAL, and DRIVE po-
sitions. Manual downshifts can be made us-
ing the Electronic Range Select (ERS) shiftSTARTING AND OPERATING
156

control. Pressing the GEAR-/GEAR+ switches
(on the steering wheel) while in the DRIVE
position will select the highest available
transmission gear, and will display that gear
limit in the instrument cluster as 1, 2, 3, etc.
Refer to “Electronic Range Select (ERS) Op-
eration” in this section for further informa-
tion. Some models will display both the se-
lected gear limit, and the actual current gear,
while in ERS mode.Transmission Limp Home Mode
Transmission function is monitored electroni-
cally 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 re-
started. 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 for-
ward gears by performing the following steps:
NOTE:
In cases where the instrument cluster mes-
sage indicates the transmission may not re-
engage after engine shutdown, perform this
procedure only in a desired location (prefer-
ably, at your authorized dealer).1. Stop the vehicle.
2. Shift the transmission into PARK, if pos-
sible. If not, shift the transmission to
NEUTRAL.
3. Turn the ignition to the OFF position. On vehicles with Keyless Enter-N-Go, 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 trans-
mission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible convenience.
Your authorized dealer has diagnostic equip-
ment to assess the condition of your trans-
mission.
If the transmission cannot be reset, autho-
rized dealer service is required.
Electronic Transmission Gear Selector
157

Electronic Range Select (ERS) Operation —
Eight-Speed Transmission
The Electronic Range Select (ERS) shift con-
trol allows the driver to limit the highest
available gear when the transmission is in
DRIVE. For example, if you set the transmis-
sion gear limit to 4 (fourth gear), the trans-
mission will not shift above fourth gear (ex-
cept to prevent engine overspeed), but will
shift through the lower gears normally.
You can switch between DRIVE and ERS
mode at any vehicle speed. When the trans-
mission gear selector is in DRIVE, the trans-
mission will operate automatically, shifting
between all available gears. Tapping the
GEAR- switch (on the steering wheel) will
activate ERS mode, display the current gear
in the instrument cluster, and set that gear as
the top available gear. Once in ERS mode,
tapping the GEAR- or GEAR+ switch will
change the top available gear.To exit ERS mode, simply push and hold the
GEAR+ switch until the gear limit display
disappears from the instrument cluster.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the ve-
hicle could skid, causing a collision or
personal injury.
Six-Speed Automatic
Transmission — 1500 Models
Only (If Equipped)
The transmission gear position display (lo-
cated in the instrument cluster) indicates the
transmission gear range. The gear selector is
mounted either on the right side of the steer-
ing column (if equipped) or on the console (if
equipped). You must press the brake pedal to
move the gear selector out of PARK (refer to
“Brake/Transmission Shift Interlock System”
in this section). To drive, move the gear
selector from PARK or NEUTRAL to the
DRIVE position. Pull the gear selector toward
you when shifting into REVERSE or PARK, or
when shifting out of PARK (column shift
only).
The electronically-controlled transmission
provides a precise shift schedule. The trans-
mission 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).
ERS ControlSTARTING AND OPERATING
158

ERS mode, gears 1 though 3 are underdrive
gears, and ERS 4 is direct drive. ERS 5 and 6
(Overdrive gears) are the same as the normal
fourth and fifth gears.
You can switch between DRIVE and ERS
mode at any vehicle speed. When the gear
selector is in the DRIVE position, the trans-
mission will operate automatically, shifting
between all available gears. Tapping the ERS
(-) switch (column shift) or tapping the gear
selector to the left (-) (console shift) will
activate ERS mode, display the current gear
in the instrument cluster, and set that gear as
the top available gear. For example, if you are
in DRIVE and are in third (direct) gear, when
you tap the gear selector/switch one time in
the (-) direction, the display will show 4 (ERS
4 is direct gear). Another tap down (-) will
shift the transmission down to ERS 3 (the
added underdrive gear). Once in ERS mode,
tapping (-) or (+) will change the top available
gear.To exit ERS mode, simply hold the gear
selector to the right (+) (console shift) or
press and hold the ERS (+) switch (column
shift) until the gear limit display disappears
from the instrument cluster.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the ve-
hicle could skid, causing a collision or
personal injury.NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), simply
press and hold the gear selector to the left (-)
(console shift) or the ERS (-) switch down
(column shift). The transmission will shift to
the range from which the vehicle can best be
slowed down.
CAUTION!
When using ERS for engine braking while
descending steep grades, be careful not to
overspeed the engine. Apply the brakes as
needed to prevent engine overspeed.
