STARTING PROCEDURESBefore starting your vehicle, adjust your seat,
adjust the inside and outside mirrors, fasten
your seat belt, and if present, instruct all other
occupants to buckle their seat belts.
WARNING!
Never leave children alone in a vehicle. Leav-
ing unattended children in a vehicle is danger-
ous for a number of reasons. A child or others
could be seriously or fatally injured. Do not
leave the key fob in the ignition switch. A child
could operate power windows, other controls,
or move the vehicle.
Automatic TransmissionThe shift lever must be in the NEUTRAL or
PARK position before you can start the engine.
Apply the brakes before shifting into any driv-
ing gear.
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 from REVERSE, PARK, or
NEUTRAL into any forward gear when the
engine is above idle speed.
• Before shifting into any gear, make sure
your foot is firmly on the brake pedal.
Using Fob With Integrated Key (Tip Start)
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or
pressing the accelerator pedal.
Do not press the accelerator. Use the Fob with
Integrated Key to briefly turn the ignition switch
to the START position and release it as soon as
the starter engages. The starter motor will con-
tinue to run, and it will disengage automatically when the engine is running. If the engine fails to
start, the starter will disengage automatically in
10 seconds. If this occurs, turn the ignition
switch to the LOCK position, wait 10 to 15 sec-
onds, then repeat the “Normal Starting” proce-
dure.
Keyless Enter-N-Go
This feature allows the
driver to operate the ig-
nition switch with the
push of a button, as long
as the ENGINE START/
STOP button is installed
and the Remote Keyless
Entry (RKE) transmitter
is in the passenger com-
partment.
Installing and Removing the ENGINE
START/STOP Button
Installing the Button
1. Remove the key fob from the ignition switch.
2. Insert the ENGINE START/STOP button into
the ignition switch with the lettering facing up
and readable.
200

3. Press firmly on the center of the button to
secure it into position.
Removing the Button
1. The ENGINE START/STOP button can be
removed from the ignition switch for key fob
use.
2. Insert the metal part of the emergency key
under the chrome bezel at the 6 o’clock posi-
tion and gently pry the button loose.
NOTE:
The ENGINE START/STOP button should
only be removed or inserted with the ignition
in the LOCK position (OFF position for Key-
less Enter-N-Go).
Normal Starting
Using the ENGINE START/STOP Button
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or
pressing the accelerator pedal.
To start the engine, the transmission must be in
PARK or NEUTRAL. Press and hold the brakepedal while pressing the ENGINE START/STOP
button once. The system takes over and at-
tempts to start the vehicle. If the vehicle fails to
start, the starter will disengage automatically
after 10 seconds. If you wish to stop the crank-
ing of the engine prior to the engine starting,
press the button again.
To Turn Off the Engine Using ENGINE
START/STOP Button
1. Place the shift lever in PARK, then press and
release the ENGINE START/STOP button.
2. The ignition switch will return to the OFF
position.
3. If the shift lever is not in PARK, the ENGINE
START/STOP button must be held for two sec-
onds and vehicle speed must be above 5 mph
(8 km/h) before the engine will shut off. The
ignition switch position will remain in the ACC
position until the shift lever is in PARK and the
button is pressed twice to the OFF position. If
the shift lever is not in PARK and the ENGINE
START/STOP button is pressed once, the EVIC
(if equipped) 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.
NOTE:
If the ignition switch is left in the ACC or
RUN (engine not running) position and the
transmission is in PARK, the system will
automatically time out after 30 minutes of
inactivity and the ignition will switch to the
OFF position.
Keyless Enter-N-Go Functions – With
Driver’s Foot OFF the Brake Pedal (In
PARK or NEUTRAL Position)
The Keyless Enter-N-Go feature operates simi-
lar to an ignition switch. It has four positions,
OFF, ACC, RUN and START. To change the
ignition switch positions without starting the
vehicle and use the accessories follow these
steps.
•
Starting with the ignition switch in the OFF
position:
• Press the ENGINE START/STOP button once
to change the ignition switch to the ACC
position (EVIC displays “IGNITION MODE
ACCESSORY”),
201

•Press the ENGINE START/STOP button a
second time to change the ignition switch to
the RUN position (EVIC displays “IGNITION
MODE RUN”),
• Press the ENGINE START/STOP button a
third time to return the ignition switch to the
OFF position (EVIC displays “IGNITION
MODE OFF”).
Extreme Cold Weather
(Below 20°F or 29°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from your autho-
rized dealer) is recommended.
If Engine Fails To Start
WARNING!
• Never pour fuel or other flammable liquids
into the throttle body air inlet opening in an
attempt to start the vehicle. This could
result in a flash fire causing serious per-
sonal injury.
(Continued)
WARNING!(Continued)
• Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission 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. Refer
to “Jump Starting” in “What To Do In Emer-
gencies” for further information.
Clearing a Flooded Engine
(Using ENGINE START/STOP Button)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather procedures, it may be flooded. To
clear any excess fuel, press and hold the brake
pedal, push the accelerator pedal all the way to
the floor and hold it, then press and release the
ENGINE START/STOP button once. The starter
motor will engage automatically, run for 10 sec- onds, and then disengage. Once this 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 fol-
lowed the “Normal Starting” or “Extreme Cold
Weather” procedures, it may be flooded. To
clear any excess fuel, push the accelerator
pedal all the way to the floor and hold it. Then,
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.
202

Normal Starting – Diesel EngineObserve the following when the engine is op-
erating.
•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. 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 engine requires twice as much power to
crank at the same RPM. The use of battery
blankets will greatly increase starting capability
at low temperatures. 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. Turn the ignition switch to the ON position.
3. Watch for the “Wait To Start Light” in the
instrument cluster. Refer to “Instrument Cluster”
in “Understanding Your Instrument Panel” for
further information. It will glow for two to ten
seconds or more, depending on engine tem-
perature. When the “Wait To Start Light” goes
out, the engine is ready to start.
4. Tip Start Feature
Do not press the accelerator. Use the Fob with
Integrated Key (FOBIK) to briefly turn the igni-
tion switch to the START position and then
release it. The starter motor will continue to run,
and it will automatically disengage when the
engine is running. If the engine fails to start, the
203

starter will disengage automatically in 20 sec-
onds. The starter can be disengaged by turn-
ing the ignition switch to the OFF position, if
required.
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 tempera-
tures below 0°F (-18°C). Long periods of idling
may be harmful to your engine because com-
bustion chamber temperatures can drop so low
that the fuel may not burn completely. Incom-
plete combustion 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 en-
gine can result in excessive white smoke
and poor engine performance. No-load en-
gine 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.
Engine Idling – In Cold Weather
Avoid prolonged idling in ambient tempera-
tures below 0°F (-18°C). Long periods of idling
may be harmful to your engine because com-
bustion chamber temperatures can drop so low
that the fuel may not burn completely. Incom-
plete combustion 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.
(Continued)
204

CAUTION!(Continued)
• Do not shift from REVERSE, PARK, or
NEUTRAL into any forward gear when the
engine is above idle speed.
• Before shifting into any gear, make sure
your foot is firmly on the brake pedal.
WARNING!
It is dangerous to move the shift lever out of
PARK or NEUTRAL if the engine speed is
higher than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could acceler-
ate 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 when your foot is
firmly on the brake pedal.
Key Ignition Park InterlockThis vehicle is equipped with a Key Ignition
Park Interlock which requires the shift lever to
be placed in PARK prior to turning the ignition
switch to the LOCK position. The key fob can
only be removed from the ignition switch when the ignition switch is in the LOCK position and
once removed the shift lever is locked in PARK.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Transmis-
sion Shift Interlock System (BTSI) that holds the
shift lever in the PARK position when the igni-
tion switch is in the LOCK position. To move the
shift lever out of the PARK position, the ignition
switch must be turned to the ON or START
position (engine running or not) and the brake
pedal must be pressed.
Brake/Transmission Interlock
Manual Override
Your vehicle may be equipped with a shift lock
manual override. The manual override may be
used in the event that the shift lever should fail
to move from PARK with the ignition switch in
the ON position and the brake pedal pressed.
To operate the shift lock manual override, per-
form the following steps:
1. Turn the ignition switch to the ON position
without starting the engine.
2. Firmly set the parking brake.
3. Remove the rubber liner from the cupholder
(located next to the shifter on the center con-
sole).
4. Using a flat-bladed screwdriver, carefully
remove the shift lock manual override cover,
which is located on the bottom of the cup-
holder.
5. Press and maintain firm pressure on the
brake pedal.
6. Using the screwdriver, reach into the manual
override opening. Press and hold the shift lock
lever down.
7. Move the shift lever into the NEUTRAL posi-
tion.
8. The vehicle may then be started in NEU-
TRAL.
Have your vehicle inspected by your local
authorized dealer if the shift lock manual over-
ride has been used.
205

Five-Speed Automatic TransmissionThe electronically-controlled transmission pro-
vides a precise shift schedule. The transmis-
sion 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.
Gear Ranges
NOTE:
After selecting any gear range, wait a mo-
ment to allow the selected gear to engage
before accelerating. This is especially im-
portant when the engine is cold. If there is a
need to restart the engine, be sure to turn
the ignition switch to the LOCK position
before restarting. Transmission gear en-
gagement may be delayed after restarting
the engine if the ignition switch is not turned
to the LOCK position first.
PARK
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never use PARK while the
vehicle is in motion. Apply the parking brakewhen leaving the vehicle in this range. Always
apply the parking brake first, then place the
shift lever into the PARK position.
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 possible
injury or damage.
• It is dangerous to move the shift lever out of
PARK or NEUTRAL if the engine speed is
higher than idle speed. If your foot is not
firmly on 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
when your right foot is firmly on the brake
pedal.
REVERSE
This range is for moving the vehicle backward.
Use only after the vehicle has come to a
complete stop. NEUTRAL
This range is used when vehicle is standing for
prolonged periods with engine running. Engine
may be started in this range. Set the parking
brake if you must leave the vehicle.
NOTE:
Towing the vehicle, coasting, or driving for
any other reason with the shift lever in
NEUTRAL can result in 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 selected only when the
vehicle is at a complete stop and the brakes
are firmly applied. The transmission automati-
cally upshifts through fifth gear. The DRIVE
position provides optimum driving characteris-
tics under all normal operating conditions.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows you to move the shift lever left (-) or right
(+) when the shift lever is in the DRIVE position,
allowing you to limit the highest available gear.
