GETTING TO KNOW YOUR INSTRUMENT PANEL125
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have OBD II and a connection
port to allow access to information related to the
performance of your emissions controls. Authorized
service technicians may need to access this information to
assist with the diagnosis and service of your vehicle and
emissions system
Úpage 184.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies the
Malfunction Indicator Light (MIL) is functioning
and is not on when the engine is running, and
that the OBD II system is ready for testing.
The OBD II system may not be ready if your vehicle was
recently serviced, recently had a depleted battery or a
battery replacement. If the OBD II system should be
determined not ready for the I/M test, your vehicle may fail
the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following:

1. Cycle the ignition switch to the ON position, but do not crank or start the engine.

NOTE:If you crank or start the engine, you will have to start this
test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the Malfunction Indicator Light
(MIL) symbol come on as part of a normal bulb check. 3. Approximately 15 seconds later, one of two things will
happen:
 The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that
your vehicle's OBD II system is not ready and you
should not proceed to the I/M station.
 The MIL will not flash at all and will remain fully illu -
minated until you place the ignition in the off posi -
tion or start the engine. This means that your
vehicle's OBD II system is ready and you can
proceed to the I/M station.
If your OBD II system is not ready, you should see an
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your vehicle
as you normally would in order for your OBD II system to
update. A recheck with the previously mentioned test
routine may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system is
ready or not, if the MIL is illuminated during normal vehicle
operation you should have your vehicle serviced before
going to the I/M station. The I/M station can fail your
vehicle because the MIL is on with the engine running.
WARNING!
 ONLY an authorized service technician should
connect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.
 If unauthorized equipment is connected to the OBD II
connection port, such as a driver-behavior tracking
device, it may:
 Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
 Access, or allow others to access, information
stored in your vehicle systems, including
personal information.

AUTOPARK
AutoPark is a supplemental feature to assist with 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.
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 conditions are met:

Vehicle is equipped with an 8-speed transmission
 Driver’s door is ajar or if the driver’s door is removed
and the driver is not on the seat (seat pad sensor
detects driver missing)
 Vehicle is not in PARK
 Vehicle speed is 1.2 mph (1.9 km/h) or less
 Ignition is switched from RUN to OFF
NOTE:For Keyless Enter ‘n Go™ equipped vehicles, the engine
will turn off and the ignition switch will change to ACC
position.
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 conditions are met:
Vehicle is equipped with an 8-speed transmission
 Driver’s door is ajar or if the driver’s door is removed
and the driver is not on the seat (seat pad sensor
detects driver missing)
 Vehicle is not in PARK
 Vehicle speed is 1.2 mph (1.9 km/h) or less
 Driver’s seat belt is unbuckled
 Brake pedal is not pressed
The message “ AutoPark Engaged Shift To P Then Shift To
Gear ” will display in the instrument cluster.
NOTE:In some cases the ParkSense graphic will be displayed in
the instrument cluster. In these cases, the gear selector
must be returned to “P” to select desired gear.
If the driver shifts into PARK while moving, the vehicle may
AutoPark.
AutoPark will engage ONLY when 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!
 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
blinking) “P” is indicated in the instrument cluster
display and on the gear selector. 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.

The message “AutoPark Disabled ” will be displayed in the
instrument cluster.
Additional customer warnings will be given when both of
these conditions are met:
 Vehicle is not in PARK
 Driver’s door is ajar
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
on the gear selector. As an added precaution, always apply
the parking brake when exiting the vehicle.
EXTENDED PARK STARTING
NOTE:Extended Park condition occurs when the vehicle has not
been started or driven for at least 30 days.
1. Install a battery charger or jumper cables to the

4. If the engine fails to start after eight attempts, allow the starter to cool for at least 10 minutes, then repeat
the procedure.
IF ENGINE FAILS TO START
If the engine fails to start after following the “Normal
Starting” procedure and the vehicle has not experience an
extended park condition, as previously defined, it may be
flooded. Push the accelerator pedal all the way to the floor
and hold it there. Crank the engine for no more than 10 to
15 seconds. This should clear any excess fuel in case the
engine is flooded. Leave the ignition in the RUN position,
release the accelerator pedal and repeat the “Normal
Starting” procedure.
EXTREME COLD WEATHER
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater
(available from an authorized dealer) is recommended.
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/h). A vehicle left in
the NEUTRAL position can roll. As an added precaution,
always apply the parking brake when exiting the vehicle.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a time. Wait
10 to 15 seconds before trying again.
WARNING!
 Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
 Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans -
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
 If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type of
start can be dangerous if done improperly
Úpage 298.
CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 10 to 15 seconds at a
time. Wait 10 to 15 seconds before trying again.

STARTING AND OPERATING129
(Continued)
AFTER STARTING
The idle speed is controlled automatically and will
decrease as the engine warms up.
STARTING THE ENGINE — DIESEL ENGINE
(IF EQUIPPED)
Before starting your vehicle, adjust your seat, both inside
and outside mirrors, and fasten your seat belts.
The starter is allowed to crank for up to 25-second
intervals. Waiting two minutes between such intervals will
protect the starter from overheating.
NOTE:Engine start up in very low ambient temperature could
result in evident white smoke. This condition will
disappear as the engine warms up.
AUTOMATIC TRANSMISSION
Start the engine with the transmission gear selector in the
PARK (P) position. Apply the brake before shifting to any
driving range.
EXTREME COLD WEATHER
The cartridge block heater clips into the engine block near
the water jacket and transfers heat to the coolant. 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 for two hours prior to start. Its use is required
for cold starts with temperatures under -20°F (-28°C).
NOTE:The engine block heater and heater cord are
factory-installed options. If your vehicle is not equipped,
heater and heater cords are available from an 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 ther -
mostat.
 A Diesel Pre-Heat system both improves engine
starting and reduces the amount of white smoke
generated by a warming engine.
WARNING!
Before exiting a vehicle, always come to a complete
stop, then shift the automatic transmission into
PARK and apply the parking brake.
 Always make sure the ignition is in the OFF position,
key fob is removed from the vehicle and vehicle is
locked.
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children 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.
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 position. A child
could operate power windows, other controls, or
move the vehicle.
 Do not leave children or animals inside parked vehi -
cles in hot weather. Interior heat buildup may cause
serious injury or death.
CAUTION!
 The engine is allowed to crank as long as
25 seconds. If the engine fails to start during this
period, please wait at least two minutes for the
starter to cool before repeating start procedure.
 If the Water in Fuel Indicator Light remains on, DO
NOT START engine before you drain the water from
the fuel filters to avoid engine damage

(Continued)

AUTOMATIC TRANSMISSION — IF EQUIPPED

You must press and hold the brake pedal while shifting out
of PARK.
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 position. 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 position.
NOTE:The transmission is NOT locked in PARK when the ignition
is in the ACC position (even though the engine will be off).
Ensure that the transmission is in PARK, and the ignition
is OFF (not in ACC position) before exiting 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 trans -
mission 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 vehicle
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 position is prop -
erly 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 reverse. You could
lose control of the vehicle and hit someone or some -
thing. Only shift into gear when the 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 position, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.
 When exiting the vehicle, always make sure the igni -
tion is in the OFF position, 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 seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
transmission gear selector.
 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 position. A child
could operate power windows, other controls, or
move the vehicle.
WARNING!CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
 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.

138STARTING AND OPERATING
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI system 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.
8–SPEED AUTOMATIC TRANSMISSION
The transmission gear range (PRNDM) is displayed both
beside the gear selector and in the instrument cluster. To
select a gear range, push 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 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
between these gears.

The transmission gear selector provides PARK, REVERSE,
NEUTRAL, DRIVE and MANUAL (AutoStick) shift positions.
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) will manually select the transmission gear, and will
display the current gear in the instrument cluster


Ú
page 140.
Transmission Gear Selector

NOTE:If the gear selector cannot be moved to the PARK,
REVERSE, or NEUTRAL position (when pushed forward), it
is probably in the AutoStick (+/-) position (beside the
DRIVE position). In AutoStick mode, the transmission gear (1, 2, 3, etc.) is displayed in the instrument cluster.
Move the gear selector to the right (into the DRIVE [D]
position) for access to PARK, REVERSE, and NEUTRAL.
Gear Ranges
Do not press the accelerator pedal when shifting out of
PARK or NEUTRAL.
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.
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.
When parking on a hill, apply the parking brake before
shifting the transmission to 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.
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.
NOTE:On four-wheel drive vehicles, be sure that the transfer
case is in a drive position.

23_JL_OM_EN_USC_t.book Page 138

STARTING AND OPERATING139
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 gear selector all the
way forward until it stops and is fully seated.
 Look at the transmission gear position display and
verify that it indicates the PARK position (P), and is not
blinking.
 With the brake pedal released, verify that the gear
selector will not move out of PARK.
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. 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 should be used for 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 to select a lower gear
Úpage 140. Under these conditions, using a lower gear will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified
depending on engine and transmission temperature as
well as vehicle speed. Normal operation will resume once
the transmission temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE position)
enables full manual control of transmission shifting also
known as AutoStick mode. 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
Úpage 140.
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.
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.
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.
