occurs, release the accelerator pedal and the
brake pedal, wait 10 to 15 seconds, then repeat
the “Normal Starting” procedure. Clearing A Flooded Engine
(Using Fob With Integrated Key)
If the engine fails to start after you have followed
the “Normal Starting” or “Extreme Cold Weather”
procedures, it may be flooded. To clear any
excess fuel:
1. Press the accelerator pedal all the way to the
floor and hold it.
2.
Turn the ignition switch to the START position
and release it as soon as the starter engages.
The starter motor will disengage automatically
in 10 seconds. Once this occurs, release the
accelerator pedal, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to
15 seconds before trying again.
After StartingThe idle speed is controlled automatically and it
will decrease as the engine warms up.
Normal Starting – Diesel EngineObserve the following when the engine is oper-
ating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Low Oil Pressure Light is off.
Cold Weather Precautions
Operation in ambient temperature below
32°F (0°C) may require special considerations.
The following chart suggests these options.
*No. 1 Ultra Low Sulfur Diesel Fuel (ULSD)
should only be used where extended arctic
conditions (-10°F/-23°C) exist.
223

NOTE:
•Use of Climatized ULSD Diesel Fuel or
Number 1 ULSD Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized ULSD Diesel Fuel is a blend of
Number 2 ULSD and Number 1 ULSD
Diesel Fuels, which reduces the tempera-
ture at which wax crystals form in fuel.
NOTE:
This engine requires the use of “Ultra Low
Sulfur Diesel Fuel.” Use of incorrect fuel
could result in exhaust system damage. Re-
fer to “Fuel Requirements – Diesel Engine”
in “Starting and Operating” for further infor-
mation.
Battery Blanket Usage
A battery loses 60% of its cranking power as the
battery temperature decreases to 0°F (-18°C).
For the same decrease in temperature, the en-
gine requires twice as much power to crank at the
same RPM. The use of battery blankets will
greatly increase starting capability at low tem-
peratures. Suitable battery blankets are available
from your authorized MOPAR® dealer.
Engine Starting Procedure
WARNING!
NEVER pour fuel or other flammable liquid
into the air inlet opening in an attempt to start
the vehicle. This could result in a flash fire
causing serious personal injury.
1. The shift lever must be in the NEUTRAL or
PARK position before you can start the engine.
2. With your foot on the brake pedal, press the
ENGINE START/STOP button.
3. Watch the “Wait To Start Light” in the instru-
ment cluster. Refer to “Instrument Cluster” in
“Understanding Your Instrument Panel” for fur-
ther information. It may glow for up to three
seconds, depending on engine temperature.
4. When the “Wait To Start Light” goes out, the
engine will automatically start.
5. After the engine starts, allow it to idle for
approximately 30 seconds before driving. This
allows oil to circulate and lubricate the turbo-
charger. Avoid prolonged idling in ambient temperatures
below 0°F (-18°C). Long periods of idling may
be harmful to your engine because combustion
chamber temperatures can drop so low that the
fuel may not burn completely. Incomplete com-
bustion allows carbon and varnish to form on
piston rings and injector nozzles. Also, the
unburned fuel can enter the crankcase, diluting
the oil and causing rapid wear to the engine.
Engine Warm Up
Avoid full throttle operation when the engine is
cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow the
oil pressure to stabilize as the engine warms up.
NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 RPM during the
warm-up period, especially in cold ambient
temperature conditions.
If temperatures are below 32°F (0°C), operate
the engine at moderate speeds for five minutes
before full loads are applied.
224

Engine Idling – In Cold Weather
Avoid prolonged idling in ambient temperatures
below 0°F (-18°C). Long periods of idling may
be harmful to your engine because combustion
chamber temperatures can drop so low that the
fuel may not burn completely. Incomplete com-
bustion allows carbon and varnish to form on
piston rings and injector nozzles. Also, the
unburned fuel can enter the crankcase, diluting
the oil and causing rapid wear to the engine.
Stopping The Engine
Before turning off your turbo diesel engine,
always allow the engine to return to normal idle
speed and run for several seconds. This as-
sures proper lubrication of the turbocharger.
This is particularly necessary after any period of
hard driving.
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 lubricating
oil and coolant to carry excess heat away from
the combustion chamber, bearings, internal
components, and turbocharger. This is espe-
cially important for turbocharged, charge air
cooled engines.AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
•Shift into PARK only after the vehicle has
come to a complete stop.
• Shift into or out of REVERSE only after the
vehicle has come to a complete stop and
the engine is at idle speed.
• Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
•
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
WARNING!
• Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a ve-
hicle while the engine is running. Before
exiting a vehicle, always apply the parking
brake, shift the transmission into PARK,
turn the engine OFF, and remove the key
fob. When the ignition is in the OFF posi-
tion, the shift lever is locked in PARK,
securing the vehicle against unwanted
movement.
• 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 reverse.
You could lose control of the vehicle and
hit someone or something. Only shift into
gear when the engine is idling normally
and your foot is firmly pressing the brake
pedal.

WARNING!(Continued)
•When leaving the vehicle, always remove
the key fob and lock your vehicle.
• Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Allow-
ing 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 shift
lever.
•
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil-
dren), and do not leave Keyless Enter-N-
Go™ in the ACC or ON/RUN position.
A child could operate power windows, other
controls, or move the vehicle.
Key Ignition Park InterlockThis vehicle is equipped with a Key Ignition Park
Interlock which requires the shift lever to be in
PARK before the ignition switch can be turned
to the OFF position. The key fob can only be
removed from the ignition when the ignition is in
the OFF position, and the shift lever is locked in
PARK whenever the ignition switch is in the
OFF position.
NOTE:
If a malfunction occurs, the system will trap
the key fob in the ignition switch 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 Transmis-
sion Shift Interlock system (BTSI) that holds the
shift lever in PARK unless the brakes are ap-
plied. To shift the transmission out of PARK, the
ignition switch must be turned to the ON/RUN
position (engine running or not) and the brake
pedal must be pressed.
Five-Speed Automatic Transmission
(3.6L and 3.0L Diesel Engine) — If
Equipped
The shift lever position display (located in the
instrument cluster) indicates the transmission
gear range. You must press the brake pedal to
move the shift lever out of PARK (refer to
“Brake/Transmission Shift Interlock System” in
this section). To drive, move the shift lever from
PARK or NEUTRAL to the DRIVE position.
The electronically-controlled transmission pro-
vides a precise shift schedule. The transmission
electronics are self-calibrating; therefore, the
first few shifts on a new vehicle may be some-
what abrupt. This is a normal condition, and
precision shifts will develop within a few hun-
dred 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.
226

The transmission shift lever has only PARK,
REVERSE, NEUTRAL, and DRIVE shift posi-
tions. Manual downshifts can be made using
the Electronic Range Select (ERS) shift control
(refer to “Electronic Range Select (ERS) Opera-
tion” in this section). Moving the shift lever to the
left or right (-/+) while in the DRIVE position will
select the highest available transmission gear,
and will display that gear in the instrument
cluster as 4, 3, 2, 1.Gear RangesDO NOT race the engine 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 espe-
cially important when the engine is cold.
• If there is a need to restart the engine, be
sure to cycle the ignition to the OFF
position before restarting. Transmission
gear engagement may be delayed after
restarting the engine if the key is not
cycled to the OFF position first.
PARK
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 leaving the vehicle in this
range. When parking on a level surface, you may place
the shift lever in PARK first, and then apply the
parking brake.
When parking on a hill, apply the parking brake
before placing the shift lever in PARK, otherwise
the load on the transmission locking mechanism
may make it difficult to move the shift lever out of
PARK. As an added precaution, turn the front
wheels toward the curb on a downhill grade and
away from the curb on an uphill grade.
WARNING!
•
Never use the PARK position as a substi-
tute for the parking brake. Always apply
the parking brake fully when parked to
guard against vehicle movement and pos-
sible injury or damage.
• Your vehicle could move and injure you
and others if it is not completely in PARK.
Check by trying to move the shift lever out
of PARK with the brake pedal released.
Make sure the transmission is in PARK
before leaving the vehicle.

WARNING!(Continued)
•When leaving the vehicle, always remove
the key fob 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 unat-
tended is dangerous for a number of rea-
sons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the shift lever.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to chil-
dren), and do not leave Keyless Enter-N-
Go™ in the ACC or ON/RUN position. A
child could operate power windows, other
controls, or move the vehicle.
CAUTION!
• Before moving the shift lever out of PARK,
you must turn the ignition switch from the
OFF position to the ON/RUN position, and
also press the brake pedal. Otherwise,
damage to the shift lever 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 engaged the shift lever
into the PARK position:
• When shifting into PARK, firmly move the
shift lever all the way forward and to the left
until it stops and is fully seated.
• Look at the shift lever position display and
verify that it indicates the PARK position.
• With brake pedal released, verify that the
shift lever will not move out of PARK.
228

REVERSE
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
NEUTRAL
Use this range when the vehicle is standing for
prolonged periods with the engine running. The
engine may be started in this range. Apply the
parking brake and shift the transmission into
PARK if you must leave 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 Operating” and “Towing A Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through underdrive first, second, and third
gears, direct fourth gear and overdrive fifth
gear. The DRIVE position provides optimum
driving characteristics under all normal operat-
ing conditions. When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the AutoStick® shift control
(refer to “AutoStick®” in this section) to select a
lower gear. Under these conditions, using a
lower gear will improve performance and ex-
tend transmission life by reducing excessive
shifting and heat buildup.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
direct gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an
authorized dealer for service without damaging
the transmission.
229

In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF
position.
4. Wait approximately 10 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 your authorized
dealer at your earliest possible conve-
nience. Your authorized dealer has diagnos-
tic equipment to determine if the problem
could recur. If the transmission cannot be
reset, authorized dealer service is required.Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear when the shift lever is in the DRIVE
position. For example, if you shift the transmis-
sion into 3 (third gear), the transmission will
never shift above third gear, but will shift down
into second and first gears normally.
You can switch between DRIVE and ERS mode
at any vehicle speed. When the shift lever is in
the DRIVE position, the transmission will oper-
ate automatically, shifting between all available
gears. Tapping the shift lever to the left (-) will
downshift the transmission, activate ERS mode,
display the current gear in the instrument clus-
ter, and maintain that gear as the top available
gear. Once in ERS mode, tapping the shift lever
to the left (-) or right (+) will change the top
available gears.
To exit ERS mode, simply press and hold the
shift lever to the right (+) until “D” is once again
displayed in the shift lever position indicator in
the instrument cluster.WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
could lose their grip and the vehicle could
skid, causing a collision or personal injury.
