Mode Control (Air Direction)
Push the mode control buttons to choose from
several patterns of air distribution.
PanelAir is directed through the outlets in the
instrument panel. These outlets can be
adjusted to direct airflow.
NOTE:
The center instrument panel outlets can be
aimed so that they are directed toward the
rear seat passengers for maximum airflow
to the rear.
Bi-Level Air is directed through the panel and
floor outlets.
NOTE:
For all settings except full cold or full hot,
there is a difference in temperature between
the upper and lower outlets. The warmer air
flows to the floor outlets. This feature gives
improved comfort during sunny but cool
conditions. Floor
Air is directed through the floor outlets
with a small amount flowing through the
defrost and side window demist outlets.
Mix Air is directed through the floor, defrost,
and side window demist outlets. This
setting works best in cold or snowy
conditions that require extra heat to the
windshield. This setting is good for maintaining
comfort while reducing moisture on the wind-
shield.
Defrost Air is directed through the windshield
and side window demist outlets. Use
this mode with maximum blower and
temperature settings for best windshield and
side window defrosting.
NOTE:
• In Floor, Mix and Defrost modes a small
amount of air will flow through the out-
board panel outlets for occupant comfort.
• The air conditioning compressor oper-
ates in Mix, Defrost, or a blend of these
modes, even if the Air Conditioning (A/C) button is not pressed. This dehumidifies
the air to help dry the windshield. To
improve fuel economy, use these modes
only when necessary.
Recirculation Control Pressing the Recirculation Control
button will put the system in recir-
culation mode. This can be used
when outside conditions such as
smoke, odors, dust, or high humid-
ity are present. Activating recircu-
lation will cause the LED in the control button to
illuminate.
NOTE:
• Continuous use of the recirculation mode
may make the inside air stuffy and win-
dow fogging may occur. Extended use of
this mode is not recommended.
• The use of the recirculation mode in cold
or damp weather could cause windows to
fog on the inside, because of moisture
buildup inside the vehicle. Select the Out-
side Air position for maximum defogging.
• The A/C will engage automatically to pre-
vent fogging when the recirculation but-

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.
